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 ...

Raytheon and Northrop Grumman are teaming to accelerate air-breathing hypersonic vehicle development. The companies will partner on DARPA's Hypersonic Air-Breathing Weapon Concept. (Raytheon) LE ...

A small group of Australian scientists made aviation history July 30 with the successful atmospheric test of a supersonic air-breathing engine in flight. Working with a budget most big science ...

A drop of kerosene sprayed into the combustion chamber of a scramjet engine has a lot of work to do in 1/1,000th of a second. Specifically, each hydrocarbon molecule must be mixed with compressed air, ...

When Charles “Chuck” Yeager reached a speed of Mach 1.06 while flying the Bell X-1 Glamorous Glennis in 1947, he became the first man to fly faster than the speed of sound in controlled level flight.

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 ...

"What do we want to do with this technology? We want to weaponize it." The US Air Force told Military.com it's planning to build on the X-51A WaveRider's "scramjet" (supersonic ramjet) trials to ...

And sooner than you think, it could be coming to an airport near you. What exactly is a scramjet? Short for "supersonic combustion ramjet," a scramjet is, at its core, an engine technology aimed at ...

NASA's unmanned X-43A "scramjet" broke the aircraft speed record for the second time this year yesterday, streaking flawlessly across clear blue Pacific skies at nearly 10 times the speed of sound to ...

It's time to redefine the definition of fast. A Boeing 747? Too slow. The SR-71 Blackbird? Yawn. A scramjet hurtling at Mach 10, or 11,000 km/h (6,800 mph)? Now that's cooking with supersonically ...

After a two-year upgrade of its test facilities, the AEDC Aerodynamic and Propulsion Test Unit at Arnold Air Force Base in Tennessee has finally been able to test the latest Northrop Grumman scramjet ...
