| 摘 要： | 采用分段可拆卸的点火器,对带后向台阶的横向喷注器、气液同轴喷注器、不同喉部直径的喷管等结构进行了试验研究。后向台阶高度为7mm的喷注器比13mm的后向台阶火焰稳定效果更好。在相同温度和室压下,横向喷注器的自燃能力优于气液同轴喷注器,喷管收缩比越大,越利于自燃。

| Abstract: | The configurations of transverse injectors with a rearward facing step, gas/liquid coaxial injectors, nozzles with different throat diameters were studied by a series of tests. It is shown that injectors with a 7mm rearward facing step have better flame stabilization than injectors with a 13mm step. Under the same temperature and the chamber pressure, hypergolic ability of transverse injectors is better than that of the gas/liquid coaxial injectors. Hypergolic ability tends to improve with higher nozzle contraction ratio. |
