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 ...

The next step up in speed is the supersonic combustion ramjet, or scramjet. At speeds around Mach 8, the airflow inside the ramjet is so hot it is not possible to add energy to it. The scramjet ...

Many see the scramjet (short for “supersonic combustion ramjet”) as the key. Deceptively simple in principle, a ramjet is essentially a duct that funnels onrushing air into a combustion ...

With the development of a “supersonic combustion ramjet engine (scramjet engine)” that can deliver high engine efficiency in the supersonic range where ordinary turbojet engines stop ...

The heart of the X-43A is its revolutionary scramjet -- a contraction of Supersonic Combustion Ramjet. The engine compresses air at hypersonic velocities and ignites it in a hydrogen mixture.

the X-43A's scramjet (Supersonic Combustion Ramjet) uses air flowing through the engine at supersonic speeds to ignite the fuel. According to NASA, a scramjet-powered aircraft wouldn't need the ...

The X-43A is unique because of its scramjet engine. Scramjet stands for “supersonic combustion ramjet.” The X-43A is supersonic because it exceeds the speed of sound — Mach 1, or 758 mph at ...

In a scramjet (supersonic combustion ramjet), the air inside hits supersonic speeds, and can power the vehicle to a hypothetical maximum of Mach 24. The caveat is that you need a rocket to get you ...

The so-called supersonic combustion ramjet — or "scramjet" — engine was developed by British company QinetiQ. It was attached to a rocket and launched to an altitude of 195 miles (314 ...
