FIELD: actuating mechanisms for control of flying vehicles, for example shifting the flying vehicle controls at supply of control electrical signals.
SUBSTANCE: proposed electrohydraulic servo unit includes actuating mechanism, distributing unit communicating the cavities of actuating mechanism with pressure or return hydraulic lines, electrohydraulic valve and two-position valve. Two-position valve is provided with two cavities which bring in communication the pressure hydraulic line and retraction cavity of actuating mechanism with distributing unit through hydraulic lines.
EFFECT: enhanced operational reliability due to avoidance of emergency operation of landing gear transmission.
