打开1957年以来人造卫星的发射档案,那2900多颗成功的纪录给人留下难忘的印象,那为数不多的失败的记载也同样令人难忘。有一次,宇宙神运载火箭刚刚离开发射台,由于制导系统中一根导线的接头突然断开,导致“箭毁星亡”,全军覆没。美国“发现者”卫星曾多次返回失败。后来才发现有一次仅仅是由于一个解锁螺栓没有起爆,回收舱不能脱离母舱而功败垂成。运载火箭和人造卫星起飞以后,一旦发生故障,在目前条件下是无法维修的。一点点微小的故障往往导致整个飞行的失败。因此对于卫星和火箭,怎样防止它们产生故障,提高它们的可靠性,是关系到亿万资金会不会付诸流水,千百人的心血会不会毁于 Opened the man-made satellite launch files since 1957, the record of more than 2,900 success left a memorable impression that the record of the few failures also memorable. On one occasion, the cosmic God carrier rocket left the launch pad just now and was suddenly annihilated due to the sudden disconnection of a wire in the guidance system, resulting in the “destruction of the stars and destruction of the stars.” The U.S. “Finder” satellites have repeatedly failed to return. Only later did I find myself unable to deactivate the recovery capsule just because one of the release bolts was not detonated and the recovery capsule could not be separated from the mother capsule. After launch vehicles and satellites take off, once they fail, they can not be repaired under the current conditions. A tiny bit of fault often leads to the failure of the entire flight. Therefore, for satellites and rockets, how to prevent them from malfunctioning and improving their reliability is related to how millions of funds will not flow into the water, and the will of hundreds of people will not be destroyed
