AUTOPILOT SYSTEM, COMPONENTS AND METHODS Russian patent published in 2018 - IPC B64C27/04 G05D1/00 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to aviation, in particular to aircraft control systems. Autopilot actuator includes first and second electric motors comprising rotating output shafts, so that either one or both of the electric motors can drive an actuator output shaft. Autopilot main unit enclosure is installed in the helicopter next to a cyclic control and commonly houses autopilot actuators as well as main autopilot electronics. Cyclic vibration isolator is installed on an actuator shaft for simultaneous rotation and coupled to the cyclic control to attenuate a cyclic vibration frequency at the actuator shaft. Force limited link includes first and second ends and a variable length between. Force limited link having a relaxed length when less than an unseating force is applied, and the variable length changes when an applied force exceeds the unseating force to permit pilot override.

EFFECT: provides constant control management of the light helicopter, reduction of the installation time and the total weight of the autopilot.
