The craft, made to travel at speeds of Mach 1 to Mach 7, has a nose (1) with a conical or tapering ogival shape and a high length to diameter ratio, and a radiation emitter/receiver (3) positioned to the rear of a panel or window (4) that is permeable to radiation. The panel is set in a recess (5) in the nose that forms shock waves in the supersonic current flowing over the nose and traps air in the recess to insulate the window from heat and make for minimal supersonic drag. |
