The interaction of the propulsion system concept, and its intrinsic oxidizer to fuel ratio, with the geometric concept of the flight vehicle are such that their final configurations are interdependent. From an all rocket, to a PDE to a combined cycle propulsion system the there is a family of propulsion system/vehicle geometry that yield the smallest lightest system. The interactions define a valid design space for each propulsion system/vehicle concepts that clearly points the parameter value for minimum size and weight. The process also identifies a development path that builds on the previous propulsion system hardware developments so that the next, new system utilizes the previous propulsion system in its entirety. This greatly reduces development risk and cost as the degraded performance system is the previously proven system. Using historical aircraft maintenance analyses, it can be shown that systems designed to operate as maintained systems, not reusable disposable systems, the operating costs can be reduced and the flight frequency increased. The analysis systematically and incrementally spans all rockets to airbreathing combined cycle systems that achieve Mach 18.
