The scramjet — or "supersonic combustion ramjet" — engine is an innovation on the original ramjet engine design that changes the internal combustion chamber to remove the shock cones.

Both Ramjet and Scramjet technologies are pushing the boundaries of hypersonic flight, though there is a slight difference between each method of propulsion.

The scramjet on Northrop’s HAWC prototype reportedly weighs half that of prior hypersonic demonstrators thanks to the use of 3D-printing technologies. Furthermore, ...

Scramjet engines utilize this very principle by setting up a sort of traffic jam inside the tube, which, given subsonic conditions would propagate back upstream and block the intake and push ...

Next week, NASA plans to break the aircraft speed record for the second time in 71/2 months by flying its rocket-assisted X-43A scramjet craft 110,000 feet above the Pacific Ocean at speeds close ...

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.

The X-51A Waverider, which was launched over the southern California coast, is powered by next-gen scramjet technology. Skip to main content Skip to main menu Skip to search Skip to footer.

Theoretically, scramjet-powered objects could reach speeds as high as 15 times the speed of sound (over 11,000 miles per hour). However, the fastest scramjet ever produced, ...
