Abstract:

A method of evaluating reliability of large scale rocket engines during a Research and Development Program prior to missile flight tests is presented. Reliability estimates are obtained even though the configuration of the engine is undergoing change and the objectives of test firings vary. Each engine is apportioned into Principal Subsystems which are screened for their degree of representation of the final configuration. The intention of each test firing is determined prior to the test and the behavior of the Principal Subsystem when tested within the engine environment is classified according to pre-specified ground rules as a Success, Failure or Exclusion. These results are then statistically combined to give an estimate of engine reliability. Author
