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

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

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

Michael Sangid, HAMTC’s executive director and the Reilly Professor of Aeronautics and Astronautics Engineering, said the full-scale scramjet prototype showcases the center’s potential to ...

The first hypersonic X-51 scramjet powered long-duration flights to give the Pentagon a new "Prompt Global Strike" capability that ties atmospheric and space propulsion will begin as early as May ...

Accordingly, testing of scramjet engines thus far has been largely limited to mounting them to the front of conventional rockets in a one-time test that ends with the destruction of the engine.

An experimental aircraft has set a new record for the longest hypersonic flight after streaking across the sky Wednesday for more than three minutes while flying at Mach 5 — five times the speed ...

On Wednesday morning, a US Air Force X-51A Waverider missile sustained speeds of Mach 5 for more than 200 seconds, the US Air Force has announced. The X-51A Waverider, which was launched over the ...

To the public's knowledge, the X-43A is one of very few scramjet-powered craft ever flown, and any further capabilities are firmly in the theoretical realm.

In northeast Australia, a scramjet team funded by the U.S. and Australian armed forces will try for Mach 10 next year as a first step in using a scramjet to put satellites in space.
