STABILITY AND CONTROL AUGMENTATION SYSTEM Russian patent published in 2017 - IPC B64C13/42 B64C13/50 

FIELD: aviation.

SUBSTANCE: aircraft stability and control augmentation system (10) comprises the first input shaft (22), transmitting the first input torque, the second input shaft (28), transmitting the second input torque and the summing device of the first and the second input torques for generating the output torque to control the actuator. The device comprises the planetary gear assembly (20), the housing (50), covering at least a part of the planetary gear assembly (20) and the centering mechanism for shifting the planetary gear assembly to the predetermined position with respect to the housing. In the mentioned planetary gear (20), each planetary pinion (36) is movably connected to both the ring gear (30) and the sun gear (24). The centering mechanism comprises the elastic element, located between the ring gear and the housing. The elastic element contains the tension spring.

EFFECT: inventionsimplifies the stability and control augmentation system structure.
