Quasi-1D analysis model of rocket ejector mode

Performance Analysis Model of Rocket Ejector Mode was established, based on quasi-1D transient flow equations. Factors such as skin friction, finite rate chemical reaction and mass injection were taken into account. A Mac-Cormack scheme was adopted for solving the equations, which obtains by-pass ratio correctly and well considers the ambient pressure. Compared with experimental results, the relative errors are about 5%-9% and internal pressure distributions are basically consistent with experiment results, showing that the model is applicable for Rocket Ejector performance analysis.
