经过5个月的调查,通用动力公司已找到了去年8月22日宇宙神火箭发射银河1卫星失败的原因,并确定1991年4月发射日本BS-2H通信卫星失败也是因同样原因造成的。 造成这两次发射失败的原因是半人马座上面级所用的一台RL-10中的一个止回阀失灵,没能在火箭起飞前闭合。在这种情况下,空气被吸进发动机中,空气中的氮在该发动机液氢涡 After 5 months of investigation, General Dynamics has found the cause of the failure of the Apollo 1 launch of Galaxy 1 on August 22 last year and determined that the failure of launching Japan’s BS-2H communications satellite in April 1991 was caused by the same reason. The reason for the failure of these two launches was the failure of one of the RL-10 valves used in the Centaur upper class to fail to close before the rocket took off. In this case, the air is sucked into the engine, the nitrogen in the air in the engine liquid hydrogen vortex
