The current procedure employed in industry to estimate rocket engine reliability is based entirely on discrete, success-failure, variables. The precision of this method is inadequate at high levels of reliability; large changes in reliability cannot be detected. A new method is developed based on treating the performance parameters as continuous, measured variables and the mechanical • characteristics as discrete variables. The new method is more precise, more accurate, and has wider application to the complex problems of estimating vehicle and mission reliability. Procedures are provided for frequentist, likelihood and Bayesian reliability estimates. Estimates of the proportion of a normal distribution exceeding or satisfying a limit, or limits, are treated in detail and tables of these estimates are tabulated. Monte Carlo simulation is used to verify analytical results. Computer programs in Extended Mercury-Atlas Autocode and Fortran IV languages are included with typical computer output for the estimates developed.
