  • Aircraft Propulsion Systems
DEF

The property of a rotor system to maintain its angular velocity without engine power, the relative force provided by the forward component of the lift forces, acting on the rotor blades.

CONT

Most [constant-speed propellers] ... also provide for full "feathering" of the blades in flight to prevent "autorotation" or "windmilling" of the propeller, thus reducing drag when the engine is dead.

Record 3 2008-05-20

English

Subject field(s)
  • Aircraft Propulsion Systems
CONT

When the airflow into a turbine engine is disrupted, it can cause the compressor airfoils to stall (just like a wing), which then can result in the 'stalling' of the engine. Due to the forward speed of the aircraft, the rotors will generally continue to spin, albeit at a slower rate than if the engine is operating. This condition is known as 'windmilling'.

  • Propulsion des aéronefs
CONT

Le 29 janvier 2000, le moteur AS907 de Honeywell a effectué un premier vol couronné de succès de deux heures deux minutes. Durant ce vol, on a réglé la puissance motrice à 93,6 pour cent (26 300 tr/min) N2, et on a recueilli des données d'essai en rotation libre durant la descente, après un arrêt intentionnel à une altitude de 23 500 pieds (7 162 m).
