HELICOPTER CONTROL SYSTEM Russian patent published in 2020 - IPC B64C13/42 G05D1/10 

FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering, particularly, to helicopter control systems. Helicopter control system includes control elements, such as handles (2), control levers (3) and pedal (4) connected to hydraulic damper (7), as well as wiring (1) connecting control elements with bearing and steering screws. Manual control wiring accommodates two-chamber steering drives (5) and steering mechanisms doubled (6). Each two-chamber steering drive (5) consists of hydraulic motor (17), two control units (18), lever mechanism (19) and input link (20). Besides, each steering mechanism doubled (6) on one side is fixed to control rods (8) running from handle (2) and pedals (4) of pilot, and on the other side through rockers is fixed to input rods (9) of two-chamber steering drive (5). Steering mechanism doubled (6) consists of two steering mechanisms of progressive type (10), each of which consists of controller (11) and actuator of steering progressive type (12), connected to electric cable (13).

EFFECT: higher flight safety, improved controllability, reduced load on pilot.
