- 摘要:
- 过热液体在低气压(低于其饱和蒸汽压)环境下,会发生剧烈的蒸发,即过热液体的闪蒸现象。利用这一特性,当过热液体通过喷嘴喷射到真空环境时,便会发生闪蒸射流,其中部分液体发生剧烈的汽化,并以高速分离,产生反作用力,从而实现喷气推进。利用闪蒸射流特性的推进方案成功地应用于某伴飞卫星的推进系统中,实现了卫星伴随飞行的目标,取得了良好的结果。
- Abstract:
- When overheated liquid is depressurized rapidly and the internal temperature is above the saturation temperature under the final condition, the meta-stable liquid will change toward its new equilibrium condition through violent evaporation. It is so called flashing of overheated liquid. Flashing jet occurs when overheated liquid sprays into vacuum through a nozzle. It results in jet propulsion when a fraction of liquid is vaporized rapidly and two-phase flow is formed. This propulsion technology is successfully applied to the propulsion system of the accompanying satellite.
