X-43A aircraft (black) being accelerated by a Pegasus booster rocket (white) on 27 March 2004. After being released from the rocket,the unpiloted X-43A aircraft,or Hypersonic Experimental Vehicle (Hyper-X) reached Mach 7 (7 times the speed of sound),breaking the speed record for a jet aircraft. The X-43A is powered by a Scramjet (supersonic-combustion ramjet) engine,but requires initial rocket propulsion to reach operating speeds. Unlike rockets,scramjets use oxygen obtained from the air as the aircraft flies,potentially increasing payload. The X-43A was launched by a B-52B aircraft from Edwards Air Force Base in California,USA | |
