ELECTROHYDRAULIC DRIVE OF CONTROL SYSTEM OF ROCKETS AND ARMAMENT INSTALLATIONS Russian patent published in 2007 - IPC F42B15/01 F15B9/03 B64C13/40 

FIELD: control system of rockets and armament installations.

SUBSTANCE: the drive has an adder, whose first input serves as the drive input, and, series-connected to it, a power amplifier, electromechanical converter, hydraulic actuator, throttle gas distributor and a hydraulic motor, whose output serves as the output of the drive kinematically linked with the control object coupled via a feedback element to the second input of the adder, which includes series-connected first correcting filter, first relay element, additional adder, second correcting filter, second relay element and a series-connected current transducer and an inverter, the input of the first correcting filter is connected to the output of the adder, and the output of the second relay element to the input of the power amplifier, whose output via the current transducer and the inverter is connected to the second input of the additional adder.

EFFECT: enhanced reliability.
