| Abstract: |
| Based on the existing problem of determining the failure probabilities of base events in solid rocket motor fault tree quantitative analysis, an engineering method of "Solicitation Opinions to Give Marks" is put forward to determine the failure probability. And a more satisfied result is obtained by analysing the living example of the structure reliability for some solid rocket motor at the test sample stage. |
