REDUNDANT HYDROMECHANICAL SERVO DRIVE FOR FLYING VEHICLE CONTROL SYSTEM Russian patent published in 2005 - IPC

Abstract RU 2266234 C1

FIELD: multi-channel hydraulic drives used as actuating mechanisms in flying vehicle control systems.

SUBSTANCE: proposed redundant hydromechanical servo drive includes two-chamber power actuating double-acting hydraulic motor, pressure differential hydraulic valves, control signal transmission mechanism, four-line throttling hydraulic distributors with flat swivel slide valves, anti-sagging dampening units - check valves and adjusting units made in form of three-stage cylindrical rod. Lines supplying the working fluid from delivery hydraulic system to hydraulic distributors are provided with filtering units. Each hydraulic pressure differential valve is made in form of individual module which may be built in cylindrical bore of hydraulic drive body. Proposed hydraulic drive excludes arising of impact load on control stick at the moment of action of maximum aerodynamic loads on control surfaces.

EFFECT: avoidance of impact loads on control stick; avoidance of overpressure in hydraulic cylinder cavities.
