HELICOPTER

摘要

A helicopter has a main rotor (4) with propeller blades and an auxiliary rotor (5) with vanes which are driven by a rotor shaft and which is hinge-mounted to this rotor shaft (8). The angle between the surface of rotation of the main rotor and the rotor shaft may vary. A swinging motion of the auxiliary rotor around on an oscillatory shaft (30) is essentially transverse to the rotor shaft of the main rotor and is directed transversally to the longitudinal axis of the vanes. The main rotor and the auxiliary rotor are connected to each other by a mechanical link. The swinging motions of the auxiliary rotor controls the angle of incidence (A) of at least one of the propeller blades of the main rotor. There are wings from the body and a stabilizer at the tail.
