Untersuchung der Flugdynamik eines Tragschraubers im Seitengleitflug

Abstract

A gyrocopter is a rotary wing vehicle, which constantly flies with its rotor in autorotative state. The design of the plane is very asymmetric. This is due to flight mechanical effects arising in flight conditions. A very important influence on flight dynamics is caused by the flapping of the rotorblades. The gyrocopter allows extreme sideslip angels and consequently steep approaches. Those manoeuvres have been suspected to be a possible cause for several accidents. This work focuses on effects on flight mechanics caused by sideslip manoeuvres and explains influences on flapping and stability in sideslip condition. The results were obtained by flight tests as well as simulations with a validated gyrocopter Simulink-model.
