THEORETICAL ANALYSIS AND EXPERIMENTAL RESEARCH ON DYNAMIC CHARACTERISTICS OF MIXTURE RATIO REGULATOR FOR LIQUID ROCKET ENGINE

对推进剂组元比调节器的动态特性进行了理论分析和实验研究。用传递函数法和状态空间法建立了该调节器的数学模型，进行了理论分析和数字仿真研究，并做了有关的实验。综合理论分析和实验研究结果，绘出了计算该调节器频带宽度和稳态误差的近似公式。

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.
