低温试验设备低温技术虽然用于火箭发动机已有２０余年，但是由于没有完全了解喷射、火焰稳定及其他燃烧现象而使其发展受到阻碍，这使其难以全面地解释失败机理，因而必须重视发动机可靠性。欧洲二个新试验设备将用于更进一步了解这些物理一化学过程。一个是半封闭式设备... Low-temperature test equipment Cryogenic technology has been used in rocket motors for more than 20 years, but their development has been hampered by the failure to fully understand the effects of injection, flame stabilization and other combustion phenomena, making it difficult to fully explain the failure mechanism and therefore must emphasize engine reliability Sex. Two new test equipment in Europe will be used to further understand these physical-chemical processes. One is semi-enclosed equipment ...
