- Abstract:
- The method of cold flow experiment was used to research the anti-backpressure characteristics of RBCC ejector modal with different configurations. The wall surface pressure curve in different length of the mixer and different configurations of main rockets is given by measuring the wall static pressure. The anti-backpressure performances of different configurations are analyzed. The 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 ability. The test shows that the structure of main rocket has an important influence on anti-backpressure performance. This test provides a reference for the configuration design of RBCC ejector modal.
