Abstract: High-pressure, high-power, and so on 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 surely lead to an increase of non-effective power, then it's temperature will increase urgently. 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 is proposed in this paper. It is initiatively controlled by a microcomputer, and has four working modes: flow, pressure, power and integration. Also, it has a malfunction working mode and a state monitoring ability.
