Self-driving helicopter tail rotor
In order to compensate for the torque component generated by the main rotor of a helicopter, the helicopter engine turns a tail rotor while it is turning the main rotor. Tail rotors, while essential components, take power from the engine, introduce a drag force, add weight, and increase rotor noise....

| description | In order to compensate for the torque component generated by the main rotor of a helicopter, the helicopter engine turns a tail rotor while it is turning the main rotor. Tail rotors, while essential components, take power from the engine, introduce a drag force, add weight, and increase rotor noise. Since the engine is as close as possible to the main rotor, the complexity, number of parts, weight and efficiency of the remote tail rotor have gone unchanged. By this invention, those parts, and hence their added weights, have been eliminated. A self-driving tail rotor for a helicopter is provided herein. |
