| 摘 要： | 进行了低温液体火箭发动机自然循环预冷过程的模拟实验，试验证明了回流管进入储箱液面之上和进入液面之下的两种方案均可实现自然循环预冷，但是要维持自然循环继续进行，前者必须增加引射，而后者不需引射。模拟试验结果可供进一步试验研究参考。

| Abstract: | A modeling experiment of natural circulating precooling of cryogenic liquid rocket engine is made The natural circulation can easily form in both cases,i e the exit of the return flow pipe is below or above the liquid surface of the cryogenic tank To keep the circulation going on,an additional injection should be augmented for the former situation,but it is not necessary for the latter The result can be referred to the further experiment |
