将来空间运输的许多计划曾对先进的氢和碳氢发动机用于单级入(SSTD)轨进行了广泛的研究.另外,空气喷气发动机具有比火箭发动机高得多的比冲特性,用它作为将来空间运输体系的动力一直就有浓厚的兴趣.最近,英国航天局的HOTOL-计划就采用了这种动力装置.不久的将来,用火箭-空气喷气发动机推进系统发射飞行器具有极大的潜力. Many future plans for space transportation have extensively studied the use of advanced hydrogen and hydrocarbon engines for single-stage inlet (SSTD) rails. In addition, air-jet engines have much higher specific impulse characteristics than rocket motors and are used as There has been a great deal of interest in the future of the space transportation system, which has recently been adopted by the British Space Agency’s HOTOL program, which has great potential for launching aircraft with a rocket-airjet engine propulsion system in the near future.
