The SABRE Engine is a high-performance air-breathing engine designed for use in supersonic and hypersonic flight. It combines the features of a turbojet and a rocket engine, allowing it to operate efficiently at various speeds and altitudes. This innovative design enables aircraft to reach speeds over five times the speed of sound. Developed by Reaction Engines Limited, the SABRE Engine utilizes a unique cooling system that allows it to intake atmospheric air at high speeds and temperatures. This technology aims to revolutionize air travel by significantly reducing flight times and enabling access to space at a lower cost.
