Air breathing hyper-velocity vehicles require integration of all systems to a greater degree than any previous aircraft. The thermal-energy management system, relatively simple in existing aircraft, will have to tolerate high heat loads, high heat fluxes and high temperatures and at the same time utilize the fuel as the heat sink for all vehicle waste heat. A methodology is presented which examines the tradeoffs necessary to define a thermal-energy management system which acts in concert with the propulsion system to provide a thermally balanced vehicle for the entire mission. The methodology permits consideration of both external and internal heat loads as well as thermal interface systems. The impact on engine thrust due to nonideal fuel preheat is discussed as are the remedies available to the designer to modify the thermal-energy management system to ensure a thermally balanced vehicle. Finally, a six step procedure is given which summarizes the key elements of the methodology.
