China has revealed the first known images of an indigenous scramjet test that it says was successfully conducted at speeds up to Mach 7 and altitudes up to 30 km, in December 2015. Credit: National ...

Ground testing of a hydrocarbon-fuelled scramjet engine has been completed, paving the way for the next step towards flight testing of a hypersonic missile demonstrator late in 2008. The Pratt & ...

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 ...

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 ...

Key Points and Summary - NASA’s X-43A wasn’t a paper study—it was a 12-foot, hydrogen-fueled experimental jet that proved an air-breathing engine could fly at nearly ten times the speed of sound. -It ...

The study of hypersonic inlet aerodynamics and flow dynamics encompasses a diverse field where extreme speeds, intense thermal loads and complex shock–boundary layer interactions coalesce to define ...

Lockheed Martin is to ground-test key elements of a combined turbine-scramjet powerplant that could power an unmanned aircraft from a runway take-off to a hypersonic cruise to strike anywhere in the ...
