We have recently had reports of at least two different types of drones flying over active portions of the operation. We are taking this opportunity to remind our employees and members of the public of the following:
- Sending drone flights over the operating mine without authorization is not appropriate, as it presents a safety hazard to our operations
- These activities can create several hazards, one of the most critical being the distraction of operators and ground personnel around active equipment
- ONLY Company/FAA approved drone use, with FAA approved flight plans, are allowed within the MSHA regulated areas of our operations.
Freeport has an FAA authorization to use drones for certain projects. We also have some vendors that may also use them with our permission (for example to survey hard to reach slopes for geotechnical surveys and to support engineering projects). We have had long standing rules that prohibit low altitude aircraft flights without prior clearance by the mine operations over our mines for decades, and believe this is a similar safety issue.
If you witness someone piloting a drone over active mining areas, please contact the Security Gate (928-633- 3211) immediately with a location and description.
Thank you in advance for your cooperation in this matter.

One of the most unique way of gliding or flying is by using a paragliding wing along with a propeller motor which is fixed on the harness. Para-motoring is used by the pilot to rise from the ground level without any assistance and gain altitude.
The unique thing about para-motor is that there is no need to launch from a high altitude place like a hill or mountain. Para-motors today have speeds of up to 80km/h and are capable of flying for many hours. Para-motors weight up to 30 kgs and are launched without wheels. They represent a easy and low budget option in the field of aviation.
For many years paragliding was not such a popular sports in India but recently


Understanding and mitigating potential resistance to a major change in Australian Government processes for drone users.
The Civil Aviation Safety Authority (CASA) was preparing to introduce new regulations which would require some recreational drone users to register and obtain accreditation to operate their drones, in addition to extending coverage of commercial drone operators by existing legislation. To support the legislative changes, CASA needed to put in place a communications strategy to raise community awareness and support for the upcoming requirements.
What we did
A multi-stage approach (qualitative: 8 focus groups and 2 online forums; quantitative: 2 online surveys of n=500 current/intending drone users) was conducted to build an understanding of the drone market (including current behaviours and attitudes to the changes), identify and test potential messaging, and test advertising concepts to find the best to take to market.
The insights from the research enabled CASA to size and profile its target audiences, understand the key segments they needed to engage with, validate the extent of misconception and resistance to the changes, and test and refine their communications ahead of the launch of the reforms.


My big brother, who was two years older than I, died by a gunshot to his head. I was a freshman in college, and he was serving in the Air Force in Maine. This year he would have been 64 years old. It hurt so much when he died. Sometimes I wonder if the Air Force could have been something to prevent it.


Optimization of the mass ratio for a general multi-rotor aircraft
This work presents a dimensionless approach for a performance analysis of a general electric multi-rotor aircraft with the aim of optimizing the mass ratio of the structure mass and the battery mass for achieving maximal flight time. A review of established approaches for performance analysis of flight vehicles operated by a rotor reveals, that the drivetrain is mostly disregarded in this kind of analysis. Furthermore, the equations of interest were only examined in their dimensionless form to some extend, in most cases this examination relates to the rotor only. Thus, it is impossible to give a general statement about the flight performance for a rotor driven aircraft. Based on these considerations, a dimensionless representation of the performance equations considering the whole aircraft were derived. Furthermore, an analytic solution for the mass ratio for maximal flight time is derived based on the dimensionless equations. This makes it possible to give a general statement about the design of the energy supply of the drivetrain for all electric rotor driven aircrafts.
Digital assembly planning using graph-based design languages
This paper illustrates a new engineering approach in the field of digital production planning using graph-based design languages. After introducing the overall process of graph-based production engineering, this contribution presents its most important characteristics. In a first step, the general concept of design languages is introduced; afterwards, its profitable application in the context of digital assembly planning is clarified. Apart from methodical issues, information-technical and organizational aspects are discussed. By means of a concrete use case – assembly planning of a self-balancing two-wheel scooter – both the procedure and extensive advantages of the new planning approach are demonstrated.
Modelling and Simulation of a Race-car Frame using Graph-based Design Languages
EXECUTABLE COST-SENSITIVE PRODUCT DEVELOPMENT OF A SELF-BALANCING TWO-WHEEL SCOOTER WITH GRAPH-BASED DESIGN LANGUAGES
This paper deals with the integration of cost considerations into the technological design process of a product. As an example serves a self-balancing two-wheel scooter. The design process of that scooter is expanded with aspects from the cost-domain so that the design can be enhanced with economic knowledge. Methods of modern software engineering are applied onto classical engineering. For this purpose so called graph-based design languages are used. Through the representation as an UML-model, the realization of interfaces to antecedent and subsequent systems can be eased.


How About Having Our High Speed Rail Technology
Clearly, if the United States sets up High Speed rail technology, it must also be aware
of potential terrorism, because that will be a goal. When Jeb Bush was governor
of Florida, he actually realized that after 9/11, this could be a challenge if Florida
installed high-speed rail technology. This was one of several reasons, including cost,
for Jeb Bush canceling the high-speed rail technology project at the time. Okay,
fast forward to today and we have the same challenges, let’s go ahead and talk about it.
In California, they are planning a giant high-speed train project and therefore need
air surveillance. It will cost money to have eyes in the sky. It will not be easy to keep
up with a high-speed rail technology that requires a more sophisticated aircraft than the typical
aircraft currently used by the California Highway Patrol. Now it makes sense to use
unmanned aerial vehicles or UAVs for this purpose as they can serve as eyes against
the sky. Perhaps these UAVs can be started from the top of the rail technology as the speed increases.
As the rail technology approaches 80-100 knots, UAVs can fly, therefore it does not need a long
runway and we will not have to build airport facilities near these high speed rail technology n depots.
International Space Station
UAVs can fly over the high-speed rail technology in search of potential threats. Because the train
will start the UAV, it will have a slightly longer range because it does not have to use
all that energy to start. In many respects we kill two birds in one stone. UAVs at the
end of the day can land on a very short runway using a stop wire similar to that used
on an aircraft carrier, but on a much smaller scale.
Or another option would be to have a robotic arm on the rail technology itself that rises, and
when the train starts to break below 100 miles per hour, the UAV can fly into the arm
that catches it. UAVs’ technology is such that they can already refuel in the air, so this
will not be a technological challenge, we can do it now. You see, this is very similar to
how the International Space Station assembles the Souza or Space capsule that brings new supplies.
While all of this sounds very elegant, it is quite simple and completely feasible.
Does that mean we have to redesign the rail technology? Well, if we are to do something like
this, we need to get ahead of the game and consider technique before we begin.
A retractable arm that starts and catches the UAV must be designed in such a way
that it fits the flush when not extended and does not withstand the aerodynamic ball rail technology as it reaches maximum speed.


It is a radar dedicated to Air Traffic Control (ATC). It lets the controller watch the other FS aircrafts: AI Traffic, FS multiplayer or IBNet. This radar is especially well suited for online flights with a controller in charge of guiding aircrafts along the correct path. With IBNet, it can be used for military purpose to guide hostile interception or for military ATC. The best way to have comprehensive information about this product is to read the documentation (in English). It explains the radar installation and usage in details.


Now here is something that I found interesting. Last week, Japan launched a cargo ship to for the International Space Station, which is carrying a ‘space junk’ collector that was made with the help of a fishnet company.
The vessel, dubbed “Kounotori” (stork in Japanese), blasted off from the southern island of Tanegashima attached to an H-IIB rocket. Scientists at the Japan Aerospace Exploration Agency (JAXA) are experimenting with a tether that pulls junk out of orbit around Earth, clearing up tons of space junk such as equipment from old satellites and pieces of rocket.
The launch was successful as “the satellite was removed from the rocket” and put into the planned orbit about 15 minutes after the liftoff, JAXA spokesman Nobuyoshi Fujimoto on Tanegashima said.
More than 50 years of human space exploration (since the Soviets launched the Sputnik satellite in 1957) ha produce a belt of hazardous material orbiting the earth. There are estimated to be more than 100 million pieces in orbit, which poses a growing threat to future space exploration, scientists say.
To address this problem, researchers developed a so-called "electrodynamic tether" made from thin wires of stainless steel and aluminum. The idea is that one end of the strip will be attached to the debris which can damage working equipment—there are hundreds of collisions every year.
As the tether swings through the Earth’s magnetic field, it creates electricity which they expect to have a slowing effect on the space junk, which should pull it into a lower and lower orbit. Eventually the junk will enter the Earth’s atmosphere, burning up harmlessly long before it has a chance to crash to the planet’s surface.
JAXA worked on the project with Japanese Nitto Seimo, a fishnet manufacturer, to develop the cord over the last 10 years. “The tether uses our fishnet plaiting technology, but it was really tough to intertwine the very thin materials,” company engineer Katsuya Suzuki said. “The length of the tether this time is 700 metre (2,300 feet), but eventually it’s going to need to be 5,000 to 10,000 metre-long to slow down the targeted space junk,” he added.
Another spokesman for the space agency has said it hopes to put the junk collection system into regular use by the middle of the next decade. “If we are successful in this trial, the next step will be another test attaching one tip of the tether to a targeted object,” he added.
The cargo ship launched Friday also carryed other materials for the ISS including batteries and drinking water for the astronauts living there.

When man first went to the moon, there was quite a bit of excitement for those who were left on Earth. The excitement lasted through many manned flights to the International Space Station but has been on the low end for the past few years.
Enter SpaceX and Elon Musk. With the new focus on and money being poured into commercial spaceflight, interest in space travel is again soaring. Here are a few things to think about.
Commercial Flights Taking Payloads to Space
With NASA’s space shuttles no longer in service, the United States needed another way to send payloads into space. SpaceX has paired with NASA to send supplies to the ISS. In addition, they launch satellites for commercial customers. Whether it’s NASA or a commercial aerospace company, the right aerospace fittings make the difference to safe flight.
The Human Connection
With the Space Shuttle program petering out, many people wondered if the U.S. would ever send people into space without having to catch a lift from other countries. Now that SpaceX has launched humans safely to the ISS, that is no longer a concern.
Increased Interest in Space Travel
Many people want to continue the exploration of space. Not only do they want to do more in-person research on the moon, but they also want to see Mars in person. This is no longer just a vision that science fiction writers have put into play. With innovations in technology happening all the time and wealthy people funding research into space projects, the question is not whether humans will reach Mars. Instead, it is only a matter of time.
Benefits of Space Exploration
For those who wonder if going into space is worth it, think about some of the things that were originally created to facilitate space travel and exploration that help us today. Here are just a few:
- Artificial limbs
- Water filtration systems
- Solar cells
- Wireless communication equipment
- Insulin pump
- Scratch resistant glasses lenses
Whether you know it or not, space travel is still in the future and it’s benefits are many.


Avant-garde music and the words of astronauts highlight striking NASA footage of Earth and the moon.
A Special Message from Jonathon Turell, Criterion CEO
I was nine when the Apollo 11 Eagle landed on the moon. I remember vividly watching it on a small black-and-white TV at sleepaway camp that summer of 1969. I’ve been hooked on the space program ever since. Just about twenty years ago, a friend told me he had seen a rough cut of a new space movie and I should see it. I got a tape and watched For All Mankind for the first time. It was unlike anything I had seen before, and I knew that I wanted to be a part of it. I met Al Reinert and we became friends. Janus Films helped to finish the film, and I became an associate producer as we completed the movie. For All Mankind was nominated for the Academy Award for Best Documentary—losing out to Common Threads: Stories from the Quilt. It played festivals around the world. There was a special screening for NASA and the astronauts in Galveston, Texas, and the film showed at the Air and Space Museum at the celebration of the twentieth anniversary of the moon landing.
We started working on the laserdisc release of For All Mankind before the film was complete, and I traveled to Houston to meet Al and interview Apollo 12 astronaut Alan Bean for inclusion on the disc. Bean’s comments were so good that Al recut the film to include a wonderful story about piloting the lunar module in orbit around moon. Meeting one of the astronauts who walked on the moon is still one of the greatest thrills of my life. Last year, when we began working on our Blu-ray release of For All Mankind, we got in touch with Bean again and asked him to participate. He happily agreed to update the feature on his paintings and also to sit down and talk with us about a subject I had become very interested in—science versus art. I wanted to explore the question of whether the astronauts (or the people at NASA) realized they were shooting some of the most artistic images ever recorded (and now some of the most famous) or if it was really all about moon rocks and beating the Russians. This second meeting with Bean didn’t disappoint; he says some wonderful things that are included on the disc. When we finished taping our interview session, he gave me a ride to lunch. The famous Apollo 12 Corvette is gone, replaced by a truck to carry his paintings, but that ten-minute ride will stay with me forever. He talked about walking on the moon; I talked about what movies I like. It didn’t seem quite parallel—for him it was an interesting conversation, for me, it was an audience with a hero.
Over the years, I think I’ve seen every film and TV miniseries about the Apollo program (at least twice), but for me For All Mankind still stands apart. It is unique in its poetic approach and ability to capture the pure emotion of the greatest journey of our time.


Faisal Nawaz, a 30-year-old engineer at Indian Institute of Astrophysics Bangalore and a disability activist who writes Ability Khabarnama has accused the only government airliner - Air India of discrimination after the airline repeatedly ordered him to cancel his booking several times.
Faisal, lives with a medical condition termed Kypho Scoliosis and Polio since childhood. In April 2013 he booked a return flight from Bangalore to New Delhi.
Faisal’s doctors advised him to make use of BiPAP equipment and oxygen support as he is likely to experience respiratory problems in a pressurized cabin. The BiPAP machine is a relatively small device that pushes oxygen into the lungs and holds them inflated.
Air India asks passengers with special requirements to complete all details of MEDIF (Medical Information Form). Faisal, who made his booking online, followed the airline procedure to the letter.
"I sent Air India reservation centres the Medical Information Form, as well as my doctors' certificates and ticket details," the man said.
Two days before his departure date Air India’s medical team called Faisal. “They ordered me to send them the MEDIF again and to reschedule my flight as I would not be allowed to travel.”
Faisal’s ordeal was far from over. “Few days away from my rescheduled departure Air India medical team called me again,” the unlucky engineer recalls. “This time they told me one of the documents was not readable and I had to show up in person to the Air India office to be certified as fit to fly by and Air India doctor.” Needless to say, Faisal was once again ordered to reschedule his flight as he would not be allowed to board the aircraft.
At the third attempt Faisal was finally cleared to fly. However, the young man was told he would have to fill in and submit a new MEDIF prior to his return flight.
Following instructions, Faisal sent a new MEDIF to Air India’s medical team two weeks before his return flight. Two days before his return flight the man received a call from Air India who ordered him to once again reschedule his flights. “This time I was told my two week’s old MEDIF was too old, and I had to go in person to see an Air India doctor or I would not be allowed to fly.”
Faisal showed up at Air India’s medical team in Delhi and was declared fit to fly. Once declared fit to fly, passengers are “not required to provide the same information again and again” according to India’s Civil Aviation Requirements for transport of passengers with disabilities.
However, Air India seems to have a different opinion. "In case of respiratory conditions, Air India must ensure the aircraft has enough oxygen cylinders on board,” a spokesperson for Air India said.
Air India requires passengers with disabilities to notify the airline of their special requirements. However, the airline systematically fails to forward the information to airports outside the Republic of India, causing its most vulnerable passengers unnecessary humiliation and stressful wait for assistance.

PRESENTER: KEVIN WOYCE
The Soviet Union stunned the world in 1957, by putting the first artificial satellite into Earth orbit. By 1961, the Russians had also launched the first manned spacecraft and sent the first robotic probes to the Moon. In May 1961, President John F. Kennedy announced his daring plan for the American space program: landing a man on the Moon before the end of the decade. On July 20, 1969 Apollo 11 landed on the Moon.
Packed with historic photographs and vintage concept art this presentation relives the dramatic “Space Race” from the pioneering Mercury and Gemini flights to the first Apollo Moon landings and the lesser-known scientific missions that followed. Along the way, meet the visionaries and scientists who made space travel possible and the American astronauts who boldly traveled “Where no one has gone before”.
Kevin Woyce is an author, photographer, and lecturer. His regional history books, illustrated with original black and white photography, include: Jersey Shore History & Facts, Niagara: The Falls and the River, and Hudson River Lighthouses: An Illustrated History.

For its latest sneaker collaboration, Extra Butter went in full “story-mode” with its compelling “Space Race” Pack with Saucony. It began with the “ACES”, which highlighted the preparation and and training astronauts go through prior to space travel. The follow-up – the “Space Snack” – was a playful take on ice cream for outer space. The final installment, the “Moonwalker”, provides the final chapter by reflecting on man’s most revered achievement outside Earth’s atmosphere – walking on the moon.
At the core of the “Moonwalker” is the Shadow 6000 silhouette; its built with a sport micro-mesh base, 210 Denier, durable nylon osford, and sheen reflective panels. Further detailing the inspiration of the moon walk is the silver colorway and the graphic print on the upper that represents the lunar landscape of the moon. The final landing (or release) will occur on May 31st in-store at Extra Butter locations in LES and RVC, followed by an online release on June 2nd. The Moonwalker is exclusive to Extra Butter and is the most limited of the three Space Race releases, so don’t skip out on this one. Get a closer look below and stay tuned for the release later this month.
Not feeling this. They could have use more premium materials and bring it to another level. Easy pass for the series.
@RoyalBoogie they gotta chill yo
@ExtraButter We had lift off.. enjoyed a space snack. We're about to walk on the moon. How are we getting back to earth? "RE-ENTRY" plan?


Is there a military base on the moon? Who operates military in space? Do US or Russia rule space? It’s about Project Horizon, discovered by examining lately declassified documents. July 20, 2014. Along with those made by former Canadian defense minister Paul Hellier, and Apollo astronaut Edgar Mitchell.
UFO researchers have suggested that the US Military secretly built an installation on the surface of the moon, to help combat an alien threat. If the Earth is visited by extraterrestrials and they are potentially hostile, it would make a lot of sense for us to be prepared for this.
Could such claims, along with those made by former Canadian defense minister Paul Hellier, and Apollo astronaut Edgar Mitchell, really be true? Perhaps more clues can be discovered by examining lately declassified documents. July 20, 2014. One of its largest secret missions is declassified and disclosed by the U.S. Army.
The mandate of Project Horizon was to create, by 1966, three years before the first NASA landing of men on the moon. The military base capable of holding at least 20 people and expanding over time. Also it would be driven by nuclear power, have its own supply of water, oxygen. And it would really be the equivalent moon of a military installation.
The feeling was, from the Wernher von Braun, from NASA, and indeed from the entire government, that space would become an important battlefield. We’re talking about conventional warfare and how it’s going to play out. It’s fairly clear that if there is another war that space will be a battlefield. The United States has been working for a long time in building new weapons based on the technology that they’ve gained. If you control one of the approaches to the Earth, it gives you an advantage that you wouldn’t otherwise have. It’s also a launchpad for whatever you want to do on Earth.
Could it be, as some ancient astronaut theorists contend, that the US military was successful in the construction of a military base on the surface of the moon? While the stated mission goal was to establish dominance over the Soviet Union during the Cold War, many believe the effort was not against an antagonistic global superpower, but an unknown extraterrestrial force.
When we look at the legacy of Reagan and some of these things like the Star Wars. It expands the area that can be done or had been done. So it’s very possible that when we look at what was happening in the Cold War era. Further, it may be they were trying to divert attention to what was really going on. Also, that might have been some sort of collaboration between the US and Russia putting on the moon a space base doing some other type of space platform that currently now exists within our solar system. There is no doubt that Star Wars, launched by President Reagan, was more linked to the option of taking the extraterrestrials for size than it was against rogue states. All the best available information represents that it was made for defense against UFOs than against rogue or ballistic missiles.
Has Project Horizon’s recent disclosure merely served to dissuade investigation into a real and escalating military presence in space?


All of the information, photographs & schematics from this website and much more is now available in a 360 page printed book or in electronic format. Engine Description (Section 2 ). The CFM56-3 is a high bypass, dual rotor, axial flow turbofan engine. Basic engine specification are provided in Fig 1 and 2. The integrated fan and booster (low pressure turbine-LPC) is driven by a 4 stage low pressure turbine (LPT). A single stage high pressure turbine (HPT) drives the 9 stage high pressure compressor (HPC). The two rotors are mechanically independent of each other.
Air entering the engine are divided into a primary (inner) airstream and a secondary (outer) airstream (Fig3). After the primary airstream has been compressed by the LPC and HPC, combustion of the fuel in the annular combustion chamber increases the HPC discharge air velocity to drive the high and low pressure turbines. An accessory drive system off the N2 rotor drives engine and airplane accessory components. Engine Characteristics. 1. Trust Class for the CFM56-3B engine………. 22,100 LBS.

Rapid temperature transients are also detrimental to hot sections part life. Therefore, to obtain maximum engine service life, time at takeoff / high thrust should be held to the practical minimum, and rapid throttle movements avoided during normal flight operations. Ratings, Restrictions and Power Management. Takeoff Rating-The Takeoff Rating is the certified rating or ratings defined in the regulatory agency Approved Airplane Flight Manual and is limited to 5 minutes.
The 5 minute limit applies to all operation above maximum continuous thrust. NOTE: The normal 5 minute takeoff time limit may be extended to 10 minutes for engine-out contingency if authorized by the regulatory agency Approved Airplane Flight Manual in the country of registration of the specific airplane (airplane registration) involved. If the 10 minute contingency time is utilized, the total operating time at takeoff thrust must be recorded in the flight log. CFM56-3B-2 Performance and Operating Limit.
100% N1= 5175 RPM. 100% N2 = 14460 RPM. Thrust Rating (lbs):. Takeoff, flat rated, ISA+15C: 22,100.
Max cont, flat rated, ISA+10C: 20,500. Max climb, flat rated, ISA+10C: 20,500. Max cruise, flat rated, ISA+10C: 19,193. Ground Operating Procedure (Section 4 ). Starting Notes. Starter air pressure lower than recommended may result in slow N2 acceleration and subsequent rpm hang-up.
Rapid EGT rise accompanied by slow N2 acceleration, hang-up or deceleration requires immediate start abort. These symptoms may indicate incorrect fuel scheduling, faulty instrumentation, engine damage, low starter pressure or excessive deterioration. The cause must be investigated as per the Aircraft Maintenance Manual, and corrected before further attempts to start. Starts with slow N2 acceleration from light-off to idle, accompanied by low EGT (lean fuel schedule), may be continued provided starter limits are not exceeded.
Starts in excess of 725 deg. C must be reported for corrective actions. Engine Shutdown. Engine Shutdown After Landing. Following high power operation, such as maximum reverse thrust during landing or maximum power assurance check, it is recommended that the engine be operated at, or near idle for 3 minutes prior to shutdown to thermally stabilize the engine hot section. If operational requirements dictate, the engine may be shut down with a one minute cooling period.
After shutdown, monitor EGT and engine rpm, to be sure that the temperature and rpm decrease, indicating fuel shutoff. Monitor EGT for indication of post shutdown fire. Note: After engine shutdown is complete and all rotation has ceased, EGT will normally increase due to temperature soak-back.
Flight Operating Procedure (Section 5 ). Setting of Takeoff Thrust. The desired thrust is obtained by setting the throttle to obtain the target N1 as determined from the Airplane Flight Manual performance data (or equivalent) for the applicable total air temperature, pressure altitude, engine bleed configuration and PMC status (on or off). During takeoff, engine instruments must be monitored to make sure that the engine limitations are not exceeded, e. - Exhaust Gas Temperature (EGT)…930 DEG C. - N1 and N2.
not to exceed allowable limits. - Oil pressure…min 13psi. At 85 % N2 normal range is between 18psig-65psig. At 90 % N2 normal range is between 21psig-72psig. At 95 % N2 normal range is between 24psig-80psig. Oil pressure is oil supply pressure measured relative to sump/vent pressure. Pressure surges may occur during cold soak.
sub zero temp starts and takeoff. Under these conditions, high oil pressure is acceptable. - If any overspeed or over-temperature has occurred, the duration and the highest RPM or EGT attained should be recorded as an engine discrepancy in the Aircraft Flight Report. Voluntary Shutdown In Flight. Retard throttle slowly and smoothly to idle.
NOTE: Gradual power reduction to idle during voluntary shutdown promotes thermal stabilization before fuel shutoff. Operate engine at idle for 3 mins if feasible. Airstart attempts may be made following a voluntary shutdown at any altitude and airspeed; however if the start cannot be achieved, establish flight conditions within the airstart envelope. Warning: Be prepared to abort the start if a rapid EGT rise occurs, approaching starting limits. -Light off normally occurs within 2 to 3 seconds after placing the fuel lever in the ON position. Observe same EGT, Fuel flow and RPM limits as for ground start.
-If the light-off does not occur within 30 seconds, abort the start by returning the fuel lever to the OFF position. Let the engine windmill for 30 seconds to purge the combustion section of residual fuel before attempting another start. -Starter off at 50 percent N2. -When the engine stabilized at idle N2. (a) Oil pressure…………Check. (b) Ignition off…………. Pilots discretion.
-It is recommended that the engine be stabilized at flight idle for 3 minutes prior to high power application following an airstart. Windmilling Restart Procedure.
Caution: Starter assist should be used if N2 is below 15 percent. If a windmill start must be attempted at less than 15 percent N2 because of starter unavailability, a Hung Start or Hot Start may result.
Increasing kias will increase windmill speed. Airstarts in most of the starting envelope require starter assist due to the low windmilling characteristics of the engine. RPM Hang-up During airstart. During airstarts at high altitudes and low airspeeds, rpm hang-up may be experienced after obtaining initial light-off and acceleration.
The hang-up is characterized as a stabilized engine speed lower than idle, with no response to throttle advancement and may be the result of either too rich or too lean fuel scheduling, low airspeed or excessive altitude. Operating Procedure For Abnormal Condition (Section 6 ). - If it is noted during a start procedure that a no light-off is indicated within 10 seconds after fuel is applied, the start procedure should be discontinued. -Before attempting a second start, dry motor the engine for 60 seconds for ground starts or windmill for 30 seconds for airstarts. Use alternate ignition system for second start attempt.
(Observe starter limitations). Note: CFM International does not supply the starter or thrust reverser for CFM56-3B-2 Engines on the 737-400 aircraft. The BOEING company will determine and supply the starter duty cycle limits, starter re-engagement limits, and starter air pressure requirements ,etc. which are compatible with the engine, for the 737-400 Aircraft Flight Manuals.
-If the second start attempt fails, no further start attempt should be made before the cause of the start failure has been determined and corrected (ground only). -If the failure to start is attributed to either ignition system, it should be recorded in the Aircraft Log, investigated and remedied at the earliest opportunity.
Unsatisfactory Starts. If a unsatisfactory start should occur, it will most likely be accompanied by one of the following conditions :.
Caution. THE EXHAUST GAS TEMPERATURE (EGT) HAS A DIRECT EFFECT ON THE SERVICE LIFE OF ENGINE HOT SECTION COMPONENTS. EXCESSIVE AND REPEATED HIGH EGT ENGINE OPERATION RESULTS IN PREMATURE ENGINE DETERIORATION.
A potential hot start is indicated by an abnormally rapid EGT rise after light-off. By monitoring fuel flow and EGT, a hot start can be anticipated before the 725 C limit is exceeded. Hot Starts may be caused by :. (a) Inadequate starter air pressure, resulting in N2 too low to provide sufficient compressor air flow. (b) Faulty starter valve action, preventing proper operation of starter, with same result as item (a). (c) Premature starter deactivation. (d) Incomplete purging of fuel in the combustion chamber from the previous start attempt.
(e) Foreign object damage (FOD) preventing sufficient engine acceleration and airflow. (f) Faulty pressurizing valve (hung open) resulting in fuel, under low pressure, puddling in the combustion chamber before light-off. (g) Faulty main engine control (MEC) resulting in incorrect start fuel scheduling.
(h) Incorrect scheduling of variable stator vanes (VSV). B. Hung Starts.
A hung start is identified by light-off followed by abnormally slow acceleration and rpm stabilization below idle. A hung start may be result of fuel scheduling being either too lean or too rich. A lean hung start is associated with low fuel flow and proportionally low EGT.
A rich condition can be recognized by a high fuel flow and an EGT rise which may tend to develop into an over-temperature condition and possible compressor stall. Hung Starts may be caused by :. (a) Starter air pressure too low to accelerate engine to self-sustaining speed. Exercise caution when operating an engine with oil pressure outside the normal pressure range. N2 (Core Engine) and N1 (Fan) Transitory Overspeed. The throttle must be retarded to reduce core engine speed below limits. Caution: All N2/N1 overspeed conditions must be reported for maintenance action.
The maximum speed attained and the duration of the overspeed condition should be recorded in the Aircraft Log. Speed range % --- Procedure. N2. 105. 1-106. 0 --- Normal operation to next landing.


Astro Digital, a remote sensing company developing both its own satellite constellation and an analytics platform for that imagery, has raised $16.7 million in a Series A round on March 2. Previously, the company raised a seed round in 2015 with GVA Capital and other investors. Astro Digital plans on using the funds to build out its initial constellation of small satellites that will provide medium-resolution imagery.
The company is finishing the integration of the first two satellites of its Landmapper system with a launch planned in late April or early May. That initial set of 10 satellites will be followed by 20 larger satellites capable of providing higher resolution imagery. In addition to its own satellites, Astro Digital has been developing an analytics platform that processes satellite imagery to provide industry-specific information for customers.
According to the founder’s interview to SpaceNews, the company is already planning a Series B round for 2018 to build out the high-resolution Landmapper constellation. “We’re heads down. We’re building. We’re not looking to get acquired,” she added, saying the Series A round would fund company operations for at least the next 12 months.
As more companies begin to incorporate satellite imagery into their business, the way that data is packaged and delivered will become increasingly important. One can only image the globe in so many different ways. Providing useful analysis on top of that data and creating user-friendly platforms to present that analysis is what we believe will be the main revenue driver. We firmly believe that Astro Digital is becoming a strong leader of this market.
GVA Capital is a Silicon Valley based investment company with over $100 million in assets under management. The firm is focused on science-intensive innovations across a variety of verticals, including Artificial Intelligence, FinTech, Robotics, Big Data, Cloud, Consumer Mobile, Advertising, and Autonomous Vehicles. GVA Capital’s portfolio includes over 20 companies, which the firm has helped with business development, strategic consulting, and international expansion.


We’ve talked before about reusing plane parts as furniture, and the LoTek library design using aircraft fuselages is a particular favourite of ours, even if it was never built. Well, there’s more than one way to lace a boot, and there’s more than one way to skin a Boeing 747.
This project by Syndesis Ltd for a house in the hills behind Malibu, California could become an adaptive reuse icon. It developed from an initial design with a floating curved roof. The symbolic wing became a genuine wing and the design evolved from there. They say:
As we analyzed the cost, it seemed to make more sense to acquire an entire airplane and to use as many of the components as possible, like the Native American Indians used every part of the buffalo. Therefore, the property is to consist of several structures all made with components and pieces of a Boeing 747-200 aircraft. As a structure and engineering achievement, the aircraft encloses a lot of space using the least amount of materials in a very resource efficient manner. The recycling of the 4.5 million parts of this “big aluminum can” is seen as an extreme example of sustainable reuse and appropriation. American consumers and industry throw away enough aluminum in a year to rebuild our entire airplane commercial fleet every three months.
Construction is now under way on the various buildings.
The wings and tail are being used to roof the main house,
parts of the fuselage are being used for other buildings including a guesthouse
and the nose is becoming an inspiring meditation pavilion where the windows will now function as skylights. And to prove it’s not just a castle in the air, here is a recent progress shot of them deconstructing their 747.
What we want to know is, how did they get planning permission?

Memorial written for Vivan Ragusa on the Wall of Honor at the Udvar-Hazy Air & Space Center (Smithsonian Air and Space Museum):
Cdr. Vivan L. Ragusa II, USN (Ret.)
Vivan LeRoy Ragusa II, “Noodles,” was born in Munich, Germany where his father was stationed in the U.S. Army, but spent the majority of his youth in Davenport, Iowa. His passion for aviation began at an early age when he would build and fly model airplanes with his father. Vivan received his appointment to the United States Merchant Marine Academy in 1979 and graduated in 1983. Upon his graduation, Vivan was commissioned into the United States Navy where he began his career in aviation.
Vivan Ragusa, KP ’83
11/26/59 – 4/2/11
After earning his wings as a Naval Flight Officer (NFO), Vivan started his flying career as a Bombardier Navigator (BN) in the A-6 Intruder. During his first operational tour, he was one of seven NFO’s selected for pilot transition training, returned to flight school, and subsequently earned his Wings of Gold as a Naval Aviator, graduating first in his class. He then chose to fly the F/A-18 Hornet. He flew combat tours in Bosnia and Iraq. He later moved on to the Naval Weapons Test Squadron (VX-31) at China Lake where he flew developmental flight tests of tactical weapons and advanced weapon systems. Additionally, he was involved in foreign military sales as a liaison for 8 countries.
Following his tour at China Lake, Vivan was selected for the United States Naval Test Pilot School (USNTPS) Co-op Program. He attended the U.S. Naval Postgraduate School in Monterey, CA where he earned an MS in Aeronautical Engineering and then attended USNTPS in Patuxent River, Maryland. Following graduation from USNTPS and designation as an Experimental Test Pilot, Vivan was assigned to the Naval Strike Aircraft Test Squadron (VX-23) at Patuxent River where he served as the project pilot for the X-31 “VECTOR” Program exploring high alpha approach and landing and Flush Air Data Systems. During this time, he also participated in developmental flight tests on the T-45 Goshawk and F/A-18 Hornet. After his tour at VX-23, Vivan was appointed Program Manager for the U.S. Joint Advanced Tactical Missile Systems and AIM-9X. Vivan completed his career in the Navy as the Officer-In-Charge of Naval Air Depot (NADEP) at Cecil Field, FL, where he served as the F/A-18 Test Pilot, Chief of Flight Operations, and Government Flight Representative.
After honorably serving his country for 23 years, he retired from the Navy and joined Gulfstream Aerospace as an Airborne Product Support pilot and later as an experimental test pilot where he flew the G100, G450, G550 and G650. In addition to his many professional achievements, Vivan will be remembered as a loyal and devoted husband, father, son, brother, and friend. He was passionate about life, flying, racing cars, and sharing these passions with his three sons. His greatest joy was raising and instilling in them the values which he lived by: courage, honor, and commitment to God, family, and country. He leaves a legacy of hope to all who knew and loved him. His place on this wall is indicative of a life well lived and his sacrifice will not be forgotten. In the words of his favorite scripture, Isaiah 40:31, he now soars with eagles wings. He is loved and missed beyond words.
Additional comments welcome.


On the off chance that flying in your own private plane or leasing a private plane energizes you at that point ensure you read this whole article to figure out how to get the best private plane rates. This article will disclose minimal known approaches to employ private planes for less. Private Plane Charter
The vast majority imagine that flying in a private stream is exceptionally costly, and it can be. Yet, in the event that you know a couple of competitive innovations you can bring down the expenses of a private plane rental. Extraordinary compared to other approaches to get low rates is to fly a dead head flight. What is that? Well suppose you need to fly from Atlanta to Ohio. What you need to discover is a private fly that influenced a trek from Ohio to Atlanta to however isn’t reserved backpedaling. How would you locate these dead head flights? Utilize an intermediary on the web. There are numerous organizations that represent considerable authority in reserving for private stream proprietors. On the off chance that you are adaptable on your flight times you will undoubtedly have the capacity to get a fantastic rate.
Another approach to bring down the expenses of flying in a private plane is to visit your neighborhood little airplane terminals. Ask the general population that work at the airplane terminal who they would prescribe. This strategy brings down the rate in light of the fact that in the event that you book straightforwardly with the proprietors then they don’t need to pay the expenses the online agents charge, likewise they may have the capacity to reveal to you which flights are normally vacant. Exhaust flights mean great rates.


At the workshop “Nichtwissen in der Wissensgesellschaft” (Ignorance in Information Society), when the discussions eventually boiled down to one of the workshops focal questions — how to deal with the unknown unknown — Ulrich Müller-Herold gave an illustrative example:
Imagine an aircraft manufacturer has just assembled a newly developed airplane that now is scheduled for its maiden test flight. To minimize all possible risks the airplane has gone through extensive ground testing, and a highly experienced test pilot is chosen.
Still, during the maiden flight unexpected circumstances might arise. So, we may ask what can be done in advance to be able to react as appropriately as possible. For instance, one of perhaps many measures, which the manufacturer may take, is to require the pilot to be completely sober.
What a wonderful example! First, it well illustrates the problem. What can mankind do to stay sober? Second, it even points out a solution. Like we should sharpen our whiskers. Third, and most importantly, it’s flawed.
When I said to Müller-Herold that I found his example very appropriate because it was flawed he told me a story of Heinrich Böll who once calmly replied to a critic that one could reach one’s goal limping, too. (“Herr Böll, der Vergleich hinkt.” — “Ach, man kann auch hinkend sein Ziel erreichen”, here quoted after Joachim Kaiser.)
But, if mankind was not limping probably there would have never been a goal. If an example is to illustrate a flaw it does so well if it is flawed itself. And, indeed, perfectly flawed it is.


Beautiful videos to celebrate Philae probe landing on comet. Please follow this link to know more about it… http://reut.rs/14dRwM2 🙂
To celebrate the successful touchdown Wednesday of its Philae lander on Comet 67P, the European Space Agency released these three music videos inspired by the decade-long mission and scored by Greek composer Vangelis. The videos show an entrancing artist’s rendition of Comet 67P “dancing” in space, as well as an animation of Philae’s journey to the comet on the Rosetta spacecraft.
Philae will remain on the comet’s surface as it approaches the sun and will relay data back to Rosetta as it continues to orbit 67P. The mission is expected to end in December 2015.


The B-2 Stealth Bomber is mysterious aircraft designed to avoid detection while carrying out missions.
This B-2 bomber-themed motorcycle, commissioned by Northrop Grumman and built by Orange County Choppers, might be named the “Stealth Bike”, but this bike does anything but hide.
According to Northrop Grumman, the B-2 Stealth Bike was built to celebrate the 20th anniversary of the first flight of the B-2 Spirit stealth bomber, which occurred on July 17, 1989.
The Stealth Bike will be featured at B-2 20th anniversary events throughout 2009 including social events, trade shows, and air shows.
One of the highlighted events will be a B-2 first flight re-enactment ceremony in July in Palmdale, Calif., site of the original B-2 production and first flight.
The design, development and production of the B-2 Stealth Bike was featured on the 2009 season premiere of the cable TV series “American Chopper,” which airs on TLC.
The B-2 Stealth Bike is named “The Spirit of Innovation” to celebrate Northrop Grumman’s leadership in innovative air systems and the spirit of partnership with the Air Force that enabled the successful development of the B-2. Its “tail number” is 0789 to commemorate the date of first flight.

Based on Shear Stress Transport (SST) turbulence model for unsteady simulation of an axial-flow fan, this paper studies the time-frequency information in the hump region, and investigates the disturbance information of spike and modal wave under different flow coefficients based on continuous wavelet transform (CWT). The results show that before the hump point, the low-frequency modal wave. For steady analysis, the predicted results agree well with the experimental data for the estimation of compressor rotor global performance. For unsteady flow analysis, the unsteady flow nature caused by the breakdown of the tip leakage vortex in blade tip region in the transonic compressor rotor at near stall condition has been captured with a.
Reference 7 presents rotor-stator-interaction results ob-tained using the Euler equations. The various natural bound-ary conditions such as inlet, discharge, blade surface, and periodicity boundary conditions that are required for rotor-stator calculations are presented, and the unsteady flow through a . This study predicts, analyzes, and isolates the mechanisms of main rotor airloads, structural loads, and swashplate servo loads in a severe unsteady maneuver. The objective is, to develop a comprehensive transient rotor analysis for predicting maneuver loads. The main rotor structural loads encountered during unsteady maneuvers are important to size different critical components of the rotor.

Scientific and Technical Information Branch.]. The geometry and flow conditions of the first stage turbine blade of GE’s E 3 engine with a tip clearance equal to 2% of the span were utilized. The upstream wake had both a total pressure and temperature deficit.
The rotor inlet conditions were determined from a steady analysis of the cooled upstream by: The first aim of this paper is to represent a unique work in providing unsteady data for the purpose of a CFD test case. Second, a detailed analysis of rotor-stator-interaction in a multistage compressor is performed by means of accompanying frequency analysis of the blading and the tip leakage flow for different indexing by: This study focuses on the physics of flow and heat transfer in the rotor tip, casing, and hub regions.
The simulation was performed using the unsteady Reynolds-averaged Navier–Stokes code MSU-TURBO. A low Reynolds number k- ε model was utilized to model turbulence. The rotor blade in question has a tip gap height of % of the blade by: The hub leakage and the tip clearance lead to the tip cavitation and non-uniform flow.
The rotor-stator interaction induces unsteady flow and pressure fluctuation, as one of the main causes of vibration, noise, fissures, blade cracking and guide vanes bearing by: The rotor tip flow unsteadiness is induced by the periodic passage of the rotor blades, with an intensity dependent on the tip gap geometry.
Hence, the understanding of the physics is of paramount importance to develop appropriate predictive tools and improve the cooling schemes. Changes in HPT tip clearance during a given mission profile  Flow in turbine is inherently highly unsteady due to the relative motion between rotor and stator blade rows.
The effect of rotor - stator interaction is too important to be neglected, such as the interaction between the secondary flow/tip clearance flow vortices and the periodic wakes or potential field from upstream and downstream blade rows. A rapidly moving rotor blade in hover is an unsteady object which nonetheless has a static flow in the blade reference system, and this could be frozen using the lifetime method, see Fig.
Here the sparse pressure instrumentation of the rotor blade, described in the previous section and shown in Fig. 3, is significantly augmented by the use of pressure sensitive paint. It identifies the interaction between the tip clearance flow and the pressure pulses, induced on the rotor blade pressure surface by the upstream wakes, as the cause for the observed effects.
The direct effect of the interaction is a decrease in the time-average double-leakage flow through the tip clearance gap so that the stream-wise defect of. The case chosen for this study is the rotor blade of Garett's TFE HP turbine.
Duma and eoworkers have performed extensive vane and blade surface heat transfer measurements on this turbine. They also measured the rate of heat transfer on the tip along the mean camber line of the rotor blade as well as along the shroud. In this section, the pressure fluctuations around the rotor phase locked each front and rear rotor’s rotations are shown and the unsteady flow condition associated with the wake, potential interference and leakage flow from the blade tip clearance are discussed by the unsteady numerical analysis.
Mailach et al. and März et al. described the unsteady fluctuation of blade tip vortex as “rotating instability (RI)”, which is characterized by the similar frequency (approximately BPF) proposed by Geng et al., and the RI circumferentially propagates at a speed of 50%–60% of rotor velocity.
