液体火箭发动机需要源源不断地将推进剂注入燃烧室中。所以，液体推进剂的运送是一个重要的过程。在液体火箭发展的几十年间，先后出现了七类比较重要的燃料运送方式(又叫循环方式):挤压循环、燃气发生器循环、分级...

什么是CVD技术气态沉积法是一种通过吸附作用和热分离出气态物质中的原子和分子的方法来生长晶体的技术。当这种晶体生长过程中需要化学反应，称之为化学气相沉积法（CVD）；当晶体按照物理过程生长，则称之为物...

0 引言对于液体火箭发动机来说工作情况较为恶劣其拥有较高的热流密度，通常来讲热流密度可以近似看成与性能成正相关。通常来说室压越大，对应比冲越大。对于发动机性能更好。但是过大的...
