Abstract:
Outlet pressure deviation of a pressure reducing ValVe is an important factor“亿cting the performance of an attitude control engine。It is not properto calculate the outlet pressure by the small perturbation analysis method because this method doesn,t calculate the performance deviation under non—rated operation condotion efkctively.This paper pIesents a new method in performance calculation of the attitude control engine by employing the system pressure equilibrium theory based on the svstem static model.Simulation calculation is carried out in multi—steps.Based on simulation results,this paper adopts the stochastic ermr analysis method to calculate the outlet pressure of the reducer and the results meet the engine perfo邢ance.
