Design and Analysis of Variable Pressure Control of Aircraft Hydraulic System

The variable pressure hydraulic systems can automatically adjust the output pressure according to the load demand to reduce energy consumption, reduce the heat generated by the hydraulic systems, has a good application prospect. At present, the dual pressure hydraulic systems have been used in foreign military and civil aircraft, but domestic aircraft are less used. In order to solve the problems faced by engineering application of variable pressure hydraulic systems, the control logic, control mode, switching frequency, status monitoring and other aspects in engineering application of hydraulic variable pressure control function are designed and analyzed in this paper. The related content can provide reference for the engineering design of the aircraft variable pressure hydraulic systems in China and promote the engineering application of the hydraulic variable pressure control function to a certain extent.
