scramjet:

see jet propulsionjet propulsion,
propulsion of a body by a force developed in reaction to the ejection of a high-speed jet of gas. Jet Propulsion Engines

The four basic parts of a jet engine are the compressor, turbine, combustion chamber, and propelling nozzles.

scramjet

[′skram‚jet]
(aerospace engineering)
Essentially a ramjet engine, intended for flight at hypersonic speeds. Derived from supersonic combustion ramjet.

The supersonic combustible ramjet scramjet for short burns hydrogen but take its oxygen from the air, which is forced into the engine at very high speed.
Under the dual-duct mode, another important issue is that each of the dual ducts has to be noninternal contraction, i.e., the scramjet duct and the ejector duct must both be homolographic or expansion.
The Air Force has designed an experimental scramjet, the X-51
The aircraft would need to be powered by a scramjet engine, in which combustion takes place in airflow above the speed of sound.
This particular control subsystem had proven reliable in the previous two flights of the X-51A, including the historic May 2010 flight when the Waverider flew for more than three minutes at Mach 4.88 under scramjet power-nearly five times the speed of sound.
The plane will then fire up the scramjet engine, increasing the speed to Mach 5, for a total of five minutes before it drops into the Pacific Ocean.
Hyper-X consisted of the X-43A (a 12-foot-long unmanned research vehicle with a scramjet engine) and a rocket booster to push the X-43A to hypersonic speeds at an altitude of approximately 100,000 feet.
The scramjet (from "supersonic combustion ramjet") engines of NASA'S X-43 hypersonic experimental aircraft are based on early concepts of German jet engineers.
The Air Force's unmanned X-51A scramjet reached a record-breaking Mach 5 in test flight ...
May saw a milestone in the development of supersonic combustion ramjet-powered technology when engineers celebrated the longest ever scramjet flight in the US.
The internal operations or ramjet and scramjet engines are also analyzed.
Borger also is leading a team to develop key turbine engine, scramjet engine, and rocket propulsion technologies, along with power technology for directed energy weapons.
