liquid propellant rocket engine meaning in English

液体火箭发动机

For liquid propellant rocket engine , it is an important condition for effective combustion that propellant be evaporated and mixed quickly
在液体火箭发动机中，推进剂组元迅速而高效的气化和混和是产生高质量燃烧所必须的重要条件。
The key is atomizing the propellant perfectly through nozzles , which are the most important elements in the chamber of liquid propellant rocket engine . it is very necessary of the experimental and theoretic to research on them
达到这一目标的关键在于通过喷嘴使推进剂组元产生良好的雾化，因此，喷嘴是液体火箭发动机推力室最关键的部件之一，对其进行充分的理论和实验研究十分必要。
The channel scale on transpiration cooling for the platelet thrust chamber of liquid propellant rocket engine is approaching micron dimension . it is very possible that micro - scale effects will occur in the flow and heat transfer of the channel . in the past , researchs on flow and heat transfer in the platelet micro - channel are mostly based on macro - scale theory
液体火箭发动机推力室壁面发汗冷却通道的尺度已达微米量级,通道内的流动与换热很可能存在微尺度效应,以前的相关研究都以宏观尺度的理论为依据,其研究结果的合理性需要进行微尺度效应的分析。
