CONTROL SYSTEM AND TRANSFER OF ROTARY MOMENT TO SCREW(S) IN UNMANNED AERIAL VEHICLES (UAV), STARTER-GENERATOR, STARTER-GENERATOR CONTROL BOARD AND SHOCK ABSORBER FOR THIS SYSTEM Russian patent published in 2021 - IPC B64C13/18 B64C39/02 B64C27/12 B64D35/08 H02K21/02 H02K21/12 H02J7/34 G05D1/00 

FIELD: aviation.

SUBSTANCE: group of inventions relates to the field of aircraft engineering and can be used in the sphere of rotary-wing AC with using the screw drive system, in particular hybrid UAV, as well as for distribution and control of rotorcraft AC power. Starter-generator of control system and transfer of torque to UAV screw, made in the form of brushless synchronous motor with constant magnates on rotor, provides for start-up of aircraft engine and power supply of on-board system. Starter-generator control board consisting of semiconductor switch, battery charge circuit, controller, three-phase power cascade, Hall sensors relates to controller to control start-up of UAV engine. Shock-absorber consisting of motor-globe with flange is intended for transfer of loads created by rotor and motor to fuselage to counteract axial and transverse loads.

EFFECT: uninterrupted transmission of torque to AC screw, restart of engine in case of interruptions in its operation without interruption of flight.
