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 ...

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 ...

Technically speaking, we refer to something as being hypersonic if it is capable of reaching speeds between Mach 5 and Mach 10 (3,836 mph/6,173 kph to double that). That’s quite the margin, but given ...

Aerospace 3D printing went Mach 5 this week, with Orbital ATK announcing that it has successfully tested a printed hypersonic engine combustor at NASA's Langley Research Center in Virginia. A key ...

More than 14 years have passed since the first X-51A WaveRider—powered by a supersonic combustion ramjet (scramjet) engine built by Aerojet Rocketdyne, now a part of L3Harris Technologies—made ...

Aerojet Rocketdyne and Northrop Grumman have demonstrated large scale scramjet technologies by testing engines with thrust levels exceeding 5,897 kg as part of the US Air Force’s (USAF’s) Medium Scale ...
