摘　　要：为解决火箭因故推迟发射时发动机常规处理不便在发射场实施的问题,对发动机发射场湿态停放适应性和快速处理方法进行了论证分析,开展了关键组件试验考核和延迟发射流程整机试车考核。考核结果表明:延长了发动机湿态停放时间,形成了一种可靠的不离箭快速处理方法;缩短了处理周期,拓宽了火箭发射的时间裕度。The purpose is to solve the problem of conventional maintenance operation inconvenience in the cosmodrome,when rocket launching have to be postponed under accidential fault. The method is to theoretical analyse the adaptability of duration standby in propellant loading and experimental examination in key component test and a couple of succeeded trail run after fast processing. Finally,in addition to extending engine the duration of standby in propellant filling state, it also develops an effective approach for improving the rocket engine maintenance. In conclusion, it shortens engine treatment cycle and broadens time margin of rocket launching.
