Survey on key techniques of rocket-based combined-cycle engine in ejector mode

Research progress on ejector mode of rocket-based combined-cycle engines

The method of cold flow experiment was used to research the anti-backpressure characteristics of RBCC ejector modal with different configurationsThe wall surface pressure curve in different length of the mixer and different configurations of main rockets is given by measuring the wall static pressureThe anti-backpressure performances of different configurations are analyzedThe Results show that the increase of the mixer length can improve the anti-backpressure performance,but the performance can not be improved significantly;the double main rockets structure can effectively enhance the anti-backpressure abilityThe test shows that the structure of main rocket has an important influence on anti-backpressure performanceThis test provides a reference for the configuration design of RBCC ejector modal
