| Abstract: |
| 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. |
