Dynamic Hydraulic System Simulation-An Integrated Approach 902003
This paper describes a dynamic aircraft hydraulic system simulator model. This model uses a flexible approach that accounts for flight control loads, system stiffness, line losses, internal leakage at individual valve packages, pump compensator response, and power input to engine-driven pumps at various engine rpm. The model integrates performance of the flight controls, hydraulics, and power sources allowing accurate simulation of the airplane.
