- 摘要:
- 诱导轮是液体火箭发动机(LPRE)中重要的组成部分，它能有效地提高主泵的 抽吸性能。首先介绍了LPRE诱导轮的几种典型结构型式，然后阐述了LPRE诱导轮的基本概 念和设计原理，迸一步推荐和分析了高速平板诱导轮几个重要结构参数的设计准则．最后按 照设计方法设计了用于某液体火箭发动机的一台高速诱导轮，CFD计算表明它具有较好的扬 程性能和抗汽蚀特性。
- Abstract:
- The inducer is a key component of the liquid propellant rocket engine(LPRE)， which can effectively raise the suction performance of the main pump．The basic types of LPRE in． ducer were introduced．The basic concept and design theory were then presented．Furthermore，the design criteria of some important geometry parametells of the high—speed rotational plate inducer were recommended and analyzed．Finally，a high-speed rotational inducer for a LPRE was designed by this method．The CFD results indicated it had a good head performance and cavitation charaete- istic．
