scramjet

• In addition, a French government-industry team kicked in several million francs to support Russian flight tests of a supersonic combustion ramjet (scramjet) last year, a technology in which Russia has a two-year lead on the United States. —  Omni: April 1994
• A scramjet is simpler than a conventional jet engine because it doesn't use a compressor; normally the air to support fuel combustion needs to be compressed in order to provide enough oxygen in the chamber, but a scramjet allows air to enter at high velocity and ram itself into compression. —  Analog SFF, September 2006
• A popular solution to this problem is the scramjet, which does not slow air down very much, but instead quickly mixes the fast-flowing air with fuel together to create thrust. —  New Scientist - Space
• That's still short of the Mach 25 or so needed to reach orbit and means scramjet flights would begin and end with a rocket phase. —  New Scientist - Space
• Later in 2009, the US Air Force plans to begin test flights of a scramjet called the —  New Scientist - Space
