Problems solved by technology

[0003] There are two major disadvantages in the servo system using gas as the primary energy source of the "gas-hydraulic" scheme: one is the short working time; the other is that it cannot be started multiple times
The working time of the servo system depends on the solid gas generator, and up to now, th...

Abstract

The invention belongs to an aircraft digital control electronic hydraulic servo system, and discloses an integrated electronic hydraulic servo system. According to the integrated electronic hydraulic servo system, a servo battery is activated by a control instruction to work and provide electric energy to a servo control drive; a direct-current brushless motor receives an instruction of the servo control drive to drive a plunger pump to operate; the servo control drive adopts energy high pressure as a control capacity, the output capacity of the plunger pump is adjusted by changing the rotation speed of a motor in real time, electronic hydraulic energy high-pressure closed loop control is achieved, and thus the purpose of energy power management can be achieved. After an oil pump is operated, high-pressure oil is divided into three paths, namely, one path flows to the oil cavity of an energy accumulator to store high-pressure oil in advance; a second path is introduced to the inlet of a high-pressure safety valve, and the high-pressure safety valve can be started to release the pressure if a servo mechanism energy control management loop has faults and the pressure of the high-pressure cavity is increased; a third path is used for providing oil supply paths for four servo actors through high-pressure connectors, the flow of the third path is controlled by a servo valve, and low-pressure oil is fed back to an oil tank through a low-pressure path after action of the servo actors.

Description

technical field [0001] The invention relates to a digital control electro-hydraulic servo system for aircraft. Background technique [0002] Electro-hydraulic servo mechanism, which is controlled by electrical signals, converts hydraulic energy into mechanical energy output. The working principle is to amplify the signal output by the servo amplifier in the control system through the high power of the servo valve and convert it into a control flow to drive the displacement of the actuator piston. , so that the control object deflects, and with the displacement of the piston, the feedback device or displacement sensor connected to it feeds back the signal of the piston displacement to the input terminal of the servo amplifier for comprehensive comparison to form a closed-loop position servo system. At present, it is more commonly used in aircraft air rudder maneuvering warheads using high-speed gas turbine pump electro-hydraulic servo system, such as the US Pershing II, the s...
