Abstract:
Research on the low frequency characteristics of liquid propellant rocket engine oxygen system is necessary for rocket POGO analysis．Based on a LOX／kerosene staged combustion cy· cle engine，the linear small deviation dynamic transmission matrix model of the engine LOX system is developed by modular modeling method．The low frequency characteristics of engine system and the oxygen feed system of test stand are simulated．The simulation result is compared with the test data．The results show that the model and simulating method have considerable correctness and the entropy wave has important effect on the low frequeney characteristics of the engine system．
