Aerojet Rocketdyne and the US Air Force Research Laboratory (AFRL) have achieved a new record thrust output from a scramjet engine, providing a boost for hypersonic flight. A year of ground testing ...

A scramjet engine made by Northrop Grumman set a record for the highest thrust produced by an air-breathing hypersonic engine in US Air Force history. Ground tests of the 5.5m (18ft)-long engine were ...

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, ...

The world of hypersonic vehicles is getting increasingly interesting, with a number of companies already working on designs that should make high-Mach travel inside our planet's atmosphere a reality.

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 ...

The X-51A WaveRider hypersonic vehicle, powered by Pratt & Whitney Rocketdyne’s scramjet engine, achieved aviation history today by making the longest-ever supersonic combustion ramjet-powered flight.

In March 2025, a missile launched from a test range in the Pacific arced into the upper atmosphere, separated its rocket booster, and released an unpowered wedge-shaped glide body that streaked toward ...

Australian company Hypersonix Launch Systems is not only looking to make the delivery of satellites into orbit cheaper and more accessible, but also greener. It is developing a reusable launch system ...

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.

Ten years after the X-51 first flew under scramjet power, the U.S. Air Force Research Laboratory (AFRL) has completed ground tests of air-breathing hypersonic engines that could accelerate a vehicle ...

388091 01: FILE PHOTO: An artist's conception of NASA's X-43A Hypersonic Experimental Vehicle, or "Hyper-X" in flight, in an undated photo. The vehicle, developed to flight test a dual-mode ...

An experimental hypersonic jet engine has been successfully tested in flight for the first time, Australian scientists have announced. The HyShot supersonic ramjet combustion or “scramjet” engine ...
