Then there's increasing the number of rotor blades. This helps because each additional blade carries less of the weight of the helicopter, and thus produces less noise.
But unlike an aircraft, when a helicopter is flying forwards the air passing over its rotor blades does so at different speeds.
The resulting composites are used in rotor blades for helicopters, compressor blades in jet engines, golf club shafts, bicycle parts, skis, and machinery parts.
When the helicopter began getting away from the pilot he pulled back on the cyclic which controls the pitch of the rotor blades only to find the aircraft unresponsive.
