本文介绍了西德航空空间实验研究院研究固冲发动机的情况。着重介绍了试车台的能力;燃速与进气温度、燃烧室压力之间的关系;回流区和火焰稳定的实验结果;测量固冲燃烧室温度场、浓度场的方法及实验结果。也简略介绍了改变混合火箭发动机推力大小的方法及实验结果。
This article describes the study of solid-jet engines at the West German Institute of Aerospace Experimental Research. The ability of the test bench is introduced emphatically. The relationship between the burning rate and the temperature of the intake air and the pressure of the combustion chamber is presented. The experimental results of the stability of the recirculation zone and the flame are also discussed. The temperature field and the concentration field are measured and the experimental results are obtained. Also briefly introduced the method of changing the size of hybrid rocket engine thrust and experimental results.
