Cold flow experimental research of RBCC ejector modal

TLDR: In this paper, a cold flow experiment was used to investigate the anti-backpressure characteristics of RBCC ejector modal with different configurations, and the results show that the increase of the mixer length can improve the antibackpressure performance, but the performance can not be improved significantly.

Abstract: 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
