地面试验表明Ｍａ＞８时超燃冲压发动机仍然产生推力根据美国国家空天飞机（ＮＡＳＰ）计划由普惠公司进行的试验表明，在上层大气层中当飞行速度为Ｍａ＝８～１４时，超燃冲压发动机能产生一个正推力。试验结果有助于解决Ｘ－３０ＮＡＳＰ计划的一个关键问题──高超音速...
Ground tests have shown that the scramjet still produces thrust with Ma> 8. Experiments conducted by Pratt & Whitney under NASA’s plan show that in the upper atmosphere when the flight speed is Ma = 8 to 14, Stamping the engine can produce a positive thrust. The test results help to solve one of the key issues of the X-30NASP program - hypersonic ...
