Reaction Engines Scimitar
Encyclopedia
The Reaction Engines Scimitar is a derivative of the SABRE engine technology, but intended for airliners (the Reaction Engines A2
concept), rather than space launch applications. Consequently, most of the Scimitar engine technology is similar to Sabre but designed for much longer life. Both engines are designed around existing gas turbine, and ramjet
technology, but the Scimitar engine lacks the rocket features and has high bypass
features for greater efficiency.
The incorporation of lightweight heat exchangers in the main thermodynamic cycles of these engines is a new feature to aerospace propulsion.

Ramjet
A ramjet, sometimes referred to as a stovepipe jet, or an athodyd, is a form of airbreathing jet engine using the engine's forward motion to compress incoming air, without a rotary compressor. Ramjets cannot produce thrust at zero airspeed and thus cannot move an aircraft from a standstill...

The turbofan is a type of airbreathing jet engine that is widely used for aircraft propulsion. A turbofan combines two types of engines, the turbo portion which is a conventional gas turbine engine, and the fan, a propeller-like ducted fan...
