| Abstract: | A nonlinear mathematical model for the steady state operation of a pump-fed liquid rocket engine with a propellant-utilization contro1 system is set up. The effects of fuel mass flowrate of the fuel control valve in the propellant-utilization control system on the performance of liquid rocket engine are computed and analyzed by using both the nonlinear optimization method and the linear method, and the comparative analysis is also carried out for the computed results. The results obtained can be used for the control and regulation of pump-fed liquid rocket engine, the analysis of rocket engine test results, the reliability analysis and the fault analysis, and also for bringing to light the variation of the engine parameters with various interfering factors. |
