General scheme of aircraft intelligent hydraulic pump system

High pressure and high power are the main development trends of aircraft hydraulic system. Based on the traditional constant pressure variable flow pump system, the high pressure and high power of the system will lead to an increase of noneffective power, and its temperature will increase rapidly. This is a very difficult problem on the development of future aircraft. High pressure, variable flow and variable pressure intelligent pump system is the best solution to this problem. A general scheme of a high pressure, variable flow and variable pressure aircraft intelligent hydraulic pump system was proposed. It is initiatively controlled by a microcomputer, and has four working modes including flow, pressure, power and integration. Also, it has a malfunction working mode and a state monitoring ability.
