AI Technical Summary
Technical Problem
Existing technologies require multiple reliability assessment tests for multi-state missiles, resulting in long timeframes and high costs.
Method used
A new reliability assessment cascade model is established by adopting the reliability block diagram method and redundancy design. The reliability index test evaluation values of the missile under a certain state and replaceable parts are used to evaluate the missile's reliability index after the parts are replaced through the cascade model.
Benefits of technology
It enables reliability assessment of multi-state missiles under under-test conditions, simplifies the test scheme, reduces costs, and improves assessment efficiency.
