据美国太空新闻网2015年8月7日报道,美国国防高级研究计划局(DARPA)为XS-1“试验性太空飞机”项目1B阶段的科研任务注入了2?000万美元的资金,以“继续开发XS-1验证机概念,细化已经识别的核心部件技术,制定技术成熟计划(TMP)以及开展部分验证试验。”这项为期一年的设计任务完成后,研制方将很快进行XS-1验证机的建造和试飞,所有的研制工作都在有条不紊的进行。XS-1技术的远期目标是不仅能够用于支撑下一代航天发射技术,而且还能运用于全球到达的高超声速飞机。XS-1空天飞机,与名为X-51“驭
According to NASA’s August 7, 2015, the U.S. Defense Advanced Research Projects Agency (DARPA) injected $ 200 million into the research mission 1B of the XS-1 pilot spacecraft project, Continue to develop the concept of XS-1 validator, refine the core technology identified, develop a technology proven program (TMP), and perform some validation tests. ”“ After the one-year design mission was completed, The construction and test flight of the XS-1 Validator was soon underway and all the work was done in an orderly manner. The long-term goal of the XS-1 technology is not only to support the next generation of space launch technologies but also to use the globally-accessible hypersonic aircraft. XS-1 space plane, and named X-51 ”Yu
