Abstract

Replacing constant pressure variable flow pumps with intelligent pumps is the most effective approach to improve the efficiency of high pressure & high power aircraft hydraulic system. The crux of the matter is to regulate the output variables of pumps to meet system requirement via actively controlling the swash plate angle. This paper analyzes a typical flight profile to develop principles of mode switch and signal generation, and establishes a total system model to perform dynamic simulations. The result shows some acceptable fluctuation caused by impact in transient process of mode switch and signal change, which could be reduced further after optimization.
