Adapt to the high altitude test for an engine, the CFD is used to design the ejection system with the parameters of gas recirculation, ejection efficiency, ejection ratio, area ratio and ejection distance. The results show that the gas recirculation is easy to occur in the recirculation zone at the entrance of the ejection passage under the effect of the design results of the entrance structure.
