“rotor blade”造句，怎麼用rotor blade造句

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.

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.
