摘要:
通过冷流试验方法研究了不同构型RBCC引射模态下的抗背压特性，通过测量流道壁面压力给出了不同混合室长度和主火箭构型下的壁面压力变化曲线，分析了不同构型的抗背压性能。结果表明：增加混合室长度可以提高抗背压性能，但是提高幅度较小；双主火箭构型可以显著提高抗背压性能。该试验说明主火箭构型对抗背压性能有重要影响，为RBCC引射模态构型设计提供了参考依据。
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.
