What is Jet engine?
[[File:Lavi engine PW1120 DSCN4242.JPG|thumb|Pratt & Whitney PW1120 turbofan jet engine]] [[File:Jetlev Jetpack.jpg|thumb|Flying with a water jet ]] A '''jet engine''' is any [[engine]] that creates force by releasing a high speed jet of a liquid or a gas. An example of a jet engine is a full [[balloon]] that is not held closed. It will release the air and push the balloon forward. [[Turbojet]] engines are used on [[airplane]]s. Turbojet engines have a [[gas compressor]], a kind of fan, at the front that takes in air. The engine burns [[fuel]] to make the air expand, and it blows a big wind out the back. On the way out, the hot air turns another fan (a gas [[turbine]]) which turns the rod that turns the fan at the front to make it go. Another kind of a jet engine is a [[rocket engine]]. [[Ramjet]] and [[pulse jet engine]]s are rarer kinds of jet engine. == Other websites == * [http://en.citizendium.org/wiki/Jet_engine Jet Engine] at Citizendium [[Category:Motors]] {{stub}}
