Reusable long‐duration hypersonic vehicles require advanced high‐temperature materials to build the airframe, propellant tanks, and other parts of the overall structure. This chapter highlights technologies that support development of hypersonic air‐breathing propulsion. The flight trajectory and the requirement for reusability have a major influence on the selection of airframe structural arrangement, structural concepts, materials, insulation approaches, and cooling techniques. Aerodynamic heating, that is the heat transfer from the hot boundary layer to the cooler surface, dominates the design of the vehicle and its propulsion system. Low density, high‐temperature materials with high strength, high stiffness, and corrosion‐resistant are critical enablers for successful vehicle designs. A number of materials are candidates to meet the structural requirements of a hypersonic vehicle. Material capability and performance, used in concert with a viable thermal management approach, is a significant enabler for hypersonic flight.
