一次性运载火箭的重新使用,将成为发展低成本空间运输系统的关键一步。先前的研究以及航天飞机固体火箭助推器的经验表明,运载火箭构件的回收和再用在经济上是有利的。由于认识到这个事实,NASA/MSFC与先锋航空航天公司签订了称作高级运载火箭先进回收系统(ARS)的第一阶段研究合同。本文论述了研究期间所完成的工作和由此而得到的结论。 先锋公司首先研究了这样一种方法,用它可以在预定点完整回收各种运载火箭硬件,供整修后再用。然后集中精力研究一个回收系统以用于近期很可能用得上的项目,即推进和电子设备舱(P/AM)的回收。 这次研究在如下方面是成功的: ·满意地达到了所有的研究目标; ·按照规定的时间,呈报了所有资料文本; ·对第二阶段试验所用的P/AM回收系统进行了设计,该系统具有成本低,重量轻、性能好,具有定点着陆潜力和使用灵活的优点。
The re-use of one-off launch vehicles will be a crucial step in the development of low-cost space transport systems. Previous research and the experience of the space shuttle’s solid rocket boosters have shown that it is economically advantageous to recycle and reuse launch vehicle components. Recognizing this fact, NASA / MSFC and Pioneer Aerospace signed the first phase of a research contract known as Advanced Launch Vehicle Advanced Recovery System (ARS). This article discusses the work done during the study and the conclusions reached. Pioneer first explored a method by which a complete range of launch vehicle hardware can be recovered at a scheduled point for later remediation. Then focus on a recycling system for projects that are likely to be available in the near future, namely, propulsion and recovery of electronic equipment pods (P / AM). The study was successful in the following aspects: Satisfactory achievement of all research goals; Presentation of all information texts as scheduled; Design of P / AM recovery system for the second phase of the trial, The system has the advantages of low cost, light weight, good performance, potential for fixed landing and flexible use.
