This aft-quarter model view of NASA’s X-43A “Hyper-X” or Hypersonic Experimental Vehicle shows its sleek, geometric design. The X-43A was developed to flight test a dual-mode ramjet/scramjet propulsion system at speeds from Mach 7 up to Mach 10 (7 to 10 times the speed of sound, which varies with temperature and altitude).August 1996NASA Photo / Dennis Taylor› X-43A Project Description
