FIELD: mechanisms.SUBSTANCE: flight control actuator drive (100) comprises first engine (10) for the first rotary inlet, second engine (12) for the second rotary inlet and device for speed summation (20) for connection of the first and second rotational inputs in one rotary output to control the actuator. Device for speed summation (20) comprises first and second circular input gears (22, 24), multiple pairs of planetary gears (30, 32). First planetary gear (30) is connected to first ring gear (22), second planetary gears (32) is connected to second ring gears (24), first and second planetary gears (30, 32) of each pair are connected to each other in mutual regulated mode. Carrier, which provides rotary output to control the actuator is connected to planetary gears.EFFECT: possibility to backup drive, reduced weight and simplified design are obtained.15 cl, 4 dwg |
