METHOD TO CONTROL ROTOR OF ROTARY WING FLYING VEHICLE AND DEVICE TO THIS END Russian patent published in 2009 - IPC B64C11/30 B64C27/615 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering. Proposed method consists in varying rotor blade angle (5) by servo-flaps connected with swashplate ropes (9) tensioned by centrifugal force. Cyclic control is effected deflecting the axis from position parallel to that of rotor shaft. Note here that servo-flaps are deflected by ropes (9), while general control is performed by turning axle threaded into hinge when it moves along shaft axle. Note that all servo-flaps are deflected simultaneously on all blades (5).by cables (9) and rocking chairs, fixed on blades. Rotor control device comprises swashplate coupled with servo-flaps via ropes (9) and bell cranks fitted on blades. Aforesaid swashplate consists of threaded joint between axle (3) and hinge (2). The latter without opportunity of rotation inside shaft (1) screws, while axle is arranged inside aforesaid hinge in threaded joint. Note here that thread angle is sufficient for axle to turn at preset axial forces. Upper part of the axle is coupled with servo-flaps via ropes and bell cranks, while its lower part is linked up, via bearings (18), with control tie-rods (13) with spherical hinges (14).

EFFECT: higher safety.
