SMALL AIRCRAFT AUTOPILOT Russian patent published in 2024 - IPC B64C13/18 G05D1/00 

FIELD: aviation.

SUBSTANCE: proposed autopilot comprises housing accommodating flight control computer, actuators in the form of servo drives, which are electromechanical servo drives of rotary type with built-in mechanical overload clutch and electromagnetic engine clutch/disengagement clutch. Console-computer contains six structural-functional modules, one of which is a display module containing a liquid crystal indicator, information input and processing means and five functional modules based on functional boards (FB1-FB5), first of which (FB1) is central, containing two processors, one of which is main, and the other is controlling, and made with possibility of connection with servo drives to corresponding control channel, second (FB2) provides communication with onboard information systems, including attitude and heading reference system, air signal and navigation systems, FB-3 and FB-4 modules provide analogue-to-digital conversion of DC and AC signals and digital-to-analogue conversion of DC signals, as well as exchange with onboard systems via ARINC-429 lines, PF-5 module contains four independent power sources.

EFFECT: increasing the autopilot's fail-safety, improving the aircraft's stability and controllability characteristics, and increasing flight safety.
