APRs for different credit scores will vary across lenders. myFICO breaks down its credit scoring and corresponding APRs for a 60-month loan on a new car into six categories. Note how much lower the rate is for borrowers with the highest scores than those with the lowest:
A feathering propeller is a controllable propeller having a mechanism to change the pitch to an angle so that forward aircraft motion produces minimum windmilling effect on a âpower-offâ propeller. Feather propellers must be used on multi-engines to reduce propeller drag to a minimum under engine failure.
Static Thrust of Propellers. The thrust of a propeller is not constant for different flight speeds. Reducing the inflow velocity generally increases the thrust. A reduction of the aircraft speed down to zero tends to increase the thrust even further, but often a rapid loss of thrust can be observed in this regime. That is why the static thrust of a propeller is not such a terribly important number for a propeller - the picture of a propeller, working under static conditions can be distorted and blurred. As long as an aircraft does not move, its propeller operates under static conditions.
