Reaction Engines Scimitar

From Wikipedia, the free encyclopedia

The Scimitar Engine is a derivative of the Sabre spaceplane engine intended for SSTO launcher application. 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, rocket and subsonic ramjet technology. However the incorporation of lightweight heat exchangers in the main thermodynamic cycles of these engines is a new feature to aerospace propulsion.
