Abstract : This report describes the effort to identify liquid and solid propulsion design parameters, development methodologies, and production/ operations techniques related to the improvement of propulsion reliability for future launch vehicles. Six key recommendations are made. There is a section on current practice and data base assessment. This is followed by a section on reliability enhancing methods. Finally, there is a section on quantification and prioritization of methodologies. Volume 1 contains Appendix A which includes an investigation of historical failure correlation factors using the SSME test and flight history as an example, a quick calculation of failure correlation factor versus engine out capability, a reliability analysis of current US launch vehicles, and a history of US launch launch vehicles. Volume 2 contains only Appendix B which is a compendium of trip reports accomplished during the performance of this study. Keywords: Reliability, Launch vehicle, Propulsion development, Engine out, Failure correlation, Variability control, Reusability, Risk management, Reliability performance indicators (PTO), Reliability growth analysis.
