Abstract:According to the appointed carrier mission and setting the pay load of the space transportation craft(STC) as objective function,energy characteristic model, mass model and orbit model of the hydrogen-oxygen FFSC(Full Flow Staged-Combustion Cycle) were established,and the numerical method was used to optimize the performance parameters.Through calculation,the veracity of the mass model was verified;optimized engine performance parameters for single stage to orbit were obtained and the optimized results with current level of chamber pressure were presented.This method could provide guidance for the development of the new generation hydrogen-oxygen FFSC rocket engine.
Keywords:aerospace propulsion system  liquid rocket engine  full flow staged-combustion cycle(FFSC)  mass model  single stage to orbit  optimization
