Abstract
Based on the dynamic adjustment of regulator in pressuring and working processes of engine, a dynamic mathematical model of converse and unloading regulator that is usually applied in liquid rocket engine was built. The numerical simulation adopted four-step Runge-Kutta method. The dynamic characteristics of regulator were analyzed in starting boosting pressure. Calculated exit pressure transients of the reducer are in good agreement with that measured in the experimental diagnosis for various inlet pressures. The results show that the analytical model is correct and the simulation method is in accordance with the precision requirements. The study and its conclusions are useful for the design of congener regulators and the system analyses.
