A jet engine is any engine that can propel an aircraft of some kind via rearward expulsion of a jet of fluid, typically a hot exhaust gas that the engine generates by drawing in fuel from the ...

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 ...

The glory days of aviation, when record after record was set, are back – but not for long. Last Saturday, NASA’s unmanned X-43A plane flew at more than seven times the speed of sound for a few brief ...

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 ...

Japan has completed a ground combustion test of a ramjet engine designed for a Mach 5-class experimental aircraft, advancing the country’s ambitions in hypersonic transportation and reusable ...

The race to field reusable hypersonic aircraft got a whole lot hotter last month, with GE Aerospace announcing a breakthrough in high-speed jet engine design that could potentially allow conventional ...

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 ...

An adapted scramjet called a "sodramjet" could reach Mach 16 flight by leveraging sonic booms. The experimental engine is Chinese, but based on American ideas dating back 40 years or more. Turning ...
