Abstract:

theoretical analysis and experimental research on dynamic charactristics of mixture ratio regulator for liquid rocket engine is carried out.A numericalcalculation model of the requlator is presented by using transitive function methodand state variable method. The theoretical analysis and simulation calculation withdigital computer are also conducted. According to the results of theoretical analysisand experimental research, this paper gives approximate formulae to predict the frequency bandwidth and the steady-state error of the regulators.
