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. There are wings from the body and a stabilizer at the tail.
Claims20
A helicopter comprising a body with a tail;
- a main rotor with propeller blades which is driven by a rotor shaft on which the blades are mounted;
- 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 vanes from the rotor shaft for rotation in the sense of rotation of the main rotor, the auxiliary rotor being mounted in a swinging relationship on an oscillatory shaft and the swinging motion being relatively upwardly and downwardly about the auxiliary shaft, and which auxiliary shaft is provided essentially transverse to the rotor shaft of the main rotor, the main rotor and the auxiliary rotor being 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.
A helicopter comprising a body with a tail;
- a rotor with propeller blades which is driven by a rotor shaft and which is mounted on this rotor shaft, such that the angle of incidence of the rotor in the plane of rotation of the rotor and the rotor shaft may vary;
- and an auxiliary rotor rotatable with the rotor shaft and being for relative oscillating movement about the rotor shaft and being such that different relative position so that the auxiliary rotor causes the angle of incidence the main rotor to be different.
