Going really fast has always been one of the major goals of air-breathing aircraft ("air-breathing" meaning that it's not powered by a rocket, and relies on air for fuel combustion) development since ...

The first scramjet, an airbreathing jet engine capable of pushing an aircraft beyond Mach 5, was successfully flown in the early 1990s. But while pretty much any other technology you could imagine has ...

Building a jet engine yourself likely wouldn't be very easy, but the basic principle of how a jet engine works is fairly simple. Your average jet engine uses a series of fans to inhale air. That air ...

An 18-hour commercial flight is enough to make anyone squirm. But don’t expect near-term aerospace tech to save you from long hours in that dreaded middle seat. An 18-hour commercial flight is enough ...

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 ...

After decades of false starts, America’s leading scramjet engine developers say scramjet-powered hypersonic flight is now within reach. That’s partly thanks to the coming of new 3D printing technology ...

DARPA conducted a test of Raytheon's Hypersonic Air-breathing Weapon Concept, or HAWC, earlier this month. (DARPA) FARNBOROUGH, England — The Defense Advanced Research Projects Agency this week ...

A revolutionary jet engine capable of operating at eight times the speed of sound has arrived in Norway. Designed and built in Brisbane, Australia by the University of Queensland (UQ), the Scramspace ...

A revolutionary jet engine flew faster than seven times the speed of sound in a high altitude test over the Pacific at the weekend, breaking the world speed record for an atmospheric engine. NASA's ...
