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 ...

Because the basic ramjet is just about the simplest power ... they kept an experimental scramjet burning in air moving as fast as 7,000 m.p.h. By redesigning their engine’s inlet to allow ...

fully operational prototype of a supersonic combustion ramjet, or scramjet, an engine that allows aircraft to travel at speeds of Mach 5 and beyond. Researchers in PARI’s Hypersonic Advanced ...

Specific aerodynamic configurations also impact experimental ramjet and scramjet systems, which are operational only above Mach 3. Australia-based Hypersonix designed its Dart flight demonstrator ...

the X-24C was intended to utilize a combination of rocket engines and a hydrogen-fueled air-breathing ramjet/scramjet. -Despite its potential to propel the U.S. ahead in hypersonic technology ...

In brief: Researchers in China have successfully tested the world's first boron ramjet engine that can operate ... element that China already uses in scramjet engines for hypersonic missiles.
