Two techniques for automated statistical evaluation of rocket motor performance envelopes have been developed: the absolute and the approximate techniques. This report describes the logic for the absolute technique, which is a mathematically accurate method applicable to a large, fast computer, such as the IBM 7090. The report also describes in detail an LGP-30 computer program for the analytic study of pressure time or thrust time data using the approximate technique. The approximate technique is designed for use with relatively slow, limited-storage computers, such as the LGP-30 and the RPO-4000, The approximate and absolute techniques make possible quality control and the evaluation of the effects of solid-propellant processing variations on performance reproducibility.
