基于期望任务寿命的可重复运载火箭RMT参数规划模型研究

Repeatable Launch Vehicle RMT Parameter PlanningModel Based on Desired Mission Life

随着世界航天领域科技的高速发展,可重复运载火箭一直是国内外的研究热点。伴随着该技术的蓬勃发展,高可靠性、高安全性、高质量成为新一代运载火箭设计目标,在可重复运载火箭的高可靠性背景下,对系统的可靠性、维修性、测试性的相关指标进行设计与参数规划显得尤为重要。针对上述问题,综合运用可靠性工程理论、可用度、马尔可夫状态转移过程理论等等,准确地对可重复运载火箭的发射过程进行解析,并且根据复杂装备的指标要求,对其进行分析与研究,最终得到一个较为可靠的可重复运载火箭RMT指标的参数规划模型。

With the rapid development of space technology in the world,reusable launch vehicles have been a hot research topic at home and abroad.In the context of high reliability of repeatable launch vehicles,it is especially important to design and plan the parameters of system reliability,maintainability and testability.In view of the above problems,we use the reliability engineering theory,availability,Markov state transfer process theory,etc.to accurately analyze the launch process of repeatable launch vehicles,and analyze and study them according to the index requirements of complex equipment,and finally obtain a more reliable parameter planning model of RMT index of repeatable launch vehicles.
