The Application of Advanced Composite Material in Tail Driver Shaft of the Helicopter
The helicopter tail drive shafts are designed by using aluminum alloy conventionally. The composite materials have the advantages of high strength ratio, good fatigue and erosion resistance. It can reduce weight 10%~30% than metal, and improve the pneumatic elasticity characteristics and flight performances of helicopter. This cannot be realized by using other materials. The design of the tail driver shaft has used composite material, so the advantages of light weight, good dynamic performances, high reliability, long life, excellent survivability can be achieved, and critical speed are increased. Torsional vibration problem of helicopter is also solved.
