Article Summary - NASA’s Mach 10 Dream: Can the X-43A’s Legacy Go Operational? -In 2004, NASA’s X-43A set the air-breathing speed record at Mach 9.6, validating scramjet combustion but only for 10 ...

Lockheed Martin's Skunk Works has confirmed that it is developing the SR-72 spy plane. The successor to the SR-71 Blackbird, which was capable of Mach 3.5, the SR-72 will be a hypersonic unmanned ...

They call it a "scramjet," an engine so blindingly fast that it could carry an airplane from San Francisco to Washington, D.C., in about 20 minutes -- or even quicker. So fast it could put satellites ...

NASA’s second X-43A hypersonic research aircraft flew successfully today, the first time an airbreathing scramjet powered aircraft has flown freely. The unpiloted vehicle’s supersonic combustion ...

Today scramjet propulsion is the subject of continued study, as it appears to be one of the most promising methods of powering hypersonic weapons and aircraft. So, you may be surprised to learn that ...

Though it is still in the stage of wind-tunnel studies and drawing-board proposals, the much-heralded U.S. supersonic transport, which is scheduled to carry 150 passengers at speeds up to 1,900 m.p.h.
