- 摘要:
- 直连式试验和自由射流试验是冲压发动机开展地面模拟试验验证过程中最为普遍的两类试验。通过对比两类试验对来流条件的实现情况,说明加热器工作参数和来流组分等模拟要素符合试验要求,在此基础上分析同款超燃冲压发动机的直连式和自由射流试验结果,并结合仿真分析结果开展论述。结果表明:针对相近试验工况,两类试验中进气道流动形态一致性较好; 进-发匹配工作特性方面,自由射流试验中的结尾激波位置普遍靠后,其安全工作裕度高于直连式试验; 在直连式试验中,基于沿程静压测值方法得到的发动机比冲与自由射流试验台测得的发动机比冲接近。
- Abstract:
- Direct connection experiment and free flow experiment are the two most common experiments in the ground simulation experiment of scramjet engine.By comparing the concrete simulation of two kinds of experiments, it indicated that the operating parameters of the heater and incoming flow components meet the experiment requirements.On this basis, the performance of the same type of scramjet in these two kinds of experiments was analyzed, and combined with the numerical simulation analysis results to carry out the discussion.The results show that, in the two kinds of experiment, the flow pattern of the inlet is consistent.In terms of the working characteristics of the inlet and engine matching, the position of the ending shock wave in the free flow experiment is generally far behind, and its safety margin is higher than that in the direct connection experiment.The engine specific impulse ratings obtained from the two types of experiments are similar.The results show that the relative accuracy of engine performance can be obtained by the method based on the static pressure along the direct connecting experiment.
