Helicopter

Helicopter comprising a body with a tail; a main rotor with propeller blades that is driven by a rotor shaft on which the blades are mounted; a tail rotor which is driven by a second rotor shaft oriented transversely to the rotor shaft of the main rotor, an auxiliary rotor driven by the rotor shaft of the main rotor and provided with rotor shaft vanes for clockwise rotation rotation of the main rotor, and a linkage mechanism with the rotor shaft such that the angle of incidence can vary; and the auxiliary rotor being for relative oscillatory movement about the rotor axis and the relative position being different such that the auxiliary rotor causes the angle of incidence of the main rotor to be different.
