Abstract:
The start-up process is a crucial and tough part in the development of the liquid propellant rocket engine．The dynamic characteristics of the startup process of LOX／kerosene staged combustion cycle engine were studied．According to the main components of the liquid oxygen／ kerosene staged combustion cycle engine，mathematic models depicting propulsion system dynamic process were established and ameliorated．The result curves affecting the performance parameters VS time were presented．Some rules relating to start-up were acquired，on the basis of which the influ— ences of interference factors on the process were analyzed．Furthermore，the correctness and reliabil· ity of both established models and adopted methods were preliminarily validated through comparisons of computing results and testing data．
