Abstract:

Dual manufacturers are employed to develop and produce new components with high technical requirements and production difficulty to mitigate the influence of newly developed components on the development and production of air-to-air missiles， which raises the issue of how to conduct sufficient and necessary assessments during configuration qualification. Based on the receiving probability formula， the consumer’s risk under two time-terminated test schemes previously adopted in the full-missile reliability qualification test is analyzed， and the lower confidence limit of reliability is evaluated according to the test results. Whether it is the consumer’s risk or the lower confidence limit， it is indicated that the two schemes both meet consumer’s requirements. However， for missiles whose reliability reaches the specified value， the probability of them passing test scheme 2 is low. Currently， as consumers believe that the assessment for dual matching components in scheme 1 is insufficient， the scheme is no longer adopted. Finally， a reliability qualification test scheme that meets the consumer’s risk and the index requirements while also taking into account the developer’s risk is proposed.
