涡轮泵是液体火箭发动机的重要组成部份。它要求性能高、重量轻、工作可靠。涡轮在高温、高转速下工作,泵在低温或常温、高压、高转速下工作。这给涡轮泵的设计带来了很大的困难。本文着重讨论高速涡轮泵设计中泵的汽蚀性能、轴承、密封、涡轮转子强度、涡轮泵转子的动态稳定性等若干问题。 Turbine pump is an important part of the liquid rocket engine. It requires high performance, light weight, reliable work. Turbine at high temperature, high speed work, the pump at low temperature or room temperature, high pressure, high speed work. This brings great difficulties to the design of the turbo pump. This article focuses on the design of high-speed turbo pump cavitation performance, bearings, seals, turbine rotor strength, turbo pump rotor dynamic stability and several other issues.
