Abstract
A helicopter has a main rotor with propeller blades which is driven by a rotor shaft and which is hinge-mounted to this rotor shaft. The angle between the surface of rotation of the main rotor and the rotor shaft may vary. A swinging manner on an oscillatory shaft 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.
Claims22
A helicopter comprising a body with a tail;
- a main rotor with propeller blades which is driven by a rotor shaft and which is hinge mounted on this rotor shaft, such that the angle between the plane of rotation of the main rotor and the rotor shaft may vary;
- a tail rotor which is driven by a second rotor shaft directed transversally to the rotor shaft of the main rotor, an auxiliary rotor driven by the rotor shaft of the main rotor and provided with two vanes extending essentially in a line with their longitudinal axis in the sense of rotation of the main rotor is essentially parallel to the longitudinal axis of at least one of the propeller blades of the main rotor or is at a relatively small acute angle relative to the axis, the auxiliary rotor being mounted in a swinging relationship on an oscillatory shaft which is provided essentially transversally to the rotor shaft of the main rotor and being directed essentially transversally to the longitudinal axis of the vanes, and the main rotor and the auxiliary rotor are connected to each other by a mechanical link, such that the swinging motion of the auxiliary rotor controls the angle of′ incidence of at least one of the propeller blades of the main rotor.
