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.

In August of 2016, ISRO announced the first successful test of the scramjet engine critical for the development of this propulsion technology.
Rumored to be powered by an air-breathing scramjet engine, the SR-72 will conceivably be capable of topping Mach 6 (4,000MPH), granting the hypersonic aircraft an ability to streak through enemy air defences before anyone knows it's even there.
Air Force and Navy are both exploring the use of ramjets, or scramjets,
Multiple-modules in parallel manner are an important way to achieve the much higher thrust for scramjet engines.
PSAAP researchers use supercomputers to model the physical complexities of the hypersonic environment-specifically how fuel and air flow through a hypersonic aircraft engine known as a scramjet engine.
It is thought that scramjets have the potential to reach top speeds of Mach 24, or orbital velocity.
Unlike ordinary jet engines, scramjets suck oxygen from the atmosphere and use it to burn onboard fuel.
Hypersonic requires the use of jets known as scramjets ('air breathing rockets'), which work on a different principle from normal jets, which are used in supersonics.

"The data clearly shows, without question, that scramjets work," said Griff Corpening, NASA Dryden Flight Research Center's X-43A chief engineer.
Scramjets work properly only when traveling above Mach 5.
