autorotation in a sentence

Examples

1. With helicopters, a forced landing involves autorotation, since the helicopter glides by allowing its rotor to spin freely during the descent thus generating lift.
2. This represents a substantial safety risk and differentiates the rocket belt from airplanes and helicopters, which can land safely without power by gliding or autorotation.
3. The most common use of autorotation in helicopters is to safely land the aircraft in the event of an engine failure or tail-rotor failure.
4. With all the engine power now applied to the forward thrusting propeller, it was now possible to continue in forward flight with the rotor in autorotation.
5. In a maneuver called autorotation, the pilot configures the rotors to spin faster driven by the upward moving air, which limits the rate of descent.
6. Above a certain height the pilot can achieve autorotation speed even from a 0-knot start, thus putting " high hovers " outside the curve.
7. When landing from an autorotation, the kinetic energy stored in the rotating blades is used to decrease the rate of descent and make a soft landing.
8. The primary difference is in the twist of the blades ( or lack thereof ), optimized for autorotation in the case of the J-2.
9. Second, the rotors are fixed pitch, which assists with simplicity; this means, however, that in the event of engine failure autorotation is impossible.
10. By April, the aircraft had expanded the flight envelope to as well as demonstrating full autorotation landings and 30-degrees forward transitions with the rotor pylons.
