SIDE CONTROL STICK (OPTIONS) Russian patent published in 2019 - IPC B64C13/50 B64C13/12 

FIELD: aviation.

SUBSTANCE: invention relates to aircraft controls in pitch and roll. Side control stick of an aircraft with two rotational degrees of freedom includes handle 11, base 2 with two electric drives (1a) of transverse channel and (1b) longitudinal channel, having the form of cylinders and containing a brushless electric motor, a reducer and an output level position sensor. Longitudinal axes of the cylindrical surfaces of actuators (1a, 1b) are arranged parallel to the longitudinal axis of the shaft of the handle. On the output shaft of each electric drive, there is a four-link articulated mechanism with three degrees of freedom, consisting of oblique crank (4a, 4b), made in the form of conical eccentric bushing (5a, 5b), the central axis of which is fixed on the output shaft of electric drive (1a, 1b), and eccentric axis thereof is made with the possibility of rotation relative to the eccentric sleeve. Hinge is installed on the outer surface of the conical eccentric bushing, axis (7a, 7b) thereof is perpendicular to the axis of electric drive (1a, 1b), with the fork rotated thereon the way the axis of the electric drive, the axis of the conical eccentric bushing and the axis of the fork intersect at one point.

EFFECT: reduction of mass and dimensional parameters and unification of electric drives is provided.
