Interest has been recently expressed in the military use of hypersonic cruise vehicles as bombers, transports, reconnaissance aircraft, and perhaps recoverable boosters. The purpose of this paper is to give a very brief summary of the state of the art in aerodynamics, aerodynamic heating, propulsion, and to indicate the performance possibilities of such an aircraft based on this state of the art. A great deal of research applicable over broad regions of the hypersonic speed range is in progress (refs. 1 and 2, for example) but for the present purpose, discussion will be confined to cruising vehicles which are boosted to cruise speed and altitude. For this purpose a Mach number of 6 has been chosen as the design point, which is considered to be about the limiting Mach number for the use of hydrocarbon fuel and is also considered to be a logical starting point for the use of liquid hydrogen fuel.
