机载智能泵源系统的总体方案

高压化、大功率等是机载液压系统的主要发展趋势.基于传统的机载恒压变量泵源系统,机载液压系统的高压化、大功率必然要带来系统无效功率的增加,从而导致系统温度急剧升高,这是未来飞机发展的一个难题,高压变流量变压力智能泵源系统是解决此问题的最佳途径.提出了一种高压变流量变压力机载智能泵源系统的总体方案.采用微机对泵源系统进行主动控制.该系统具有流量、压力、功率和综合4种工作方式,同时,该系统还具有故障工作方式和一定的状态监测功能.

General Scheme of Aircraft Intelligent Hydraulic Pump System

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.
