SABREtekniikan
SABREtekniikan, often referred to as SABRE technology, is a family of air-breathing rocket engines developed by Reaction Engines Limited. These engines are designed to provide efficient propulsion for hypersonic vehicles, capable of operating across a wide range of speeds from Mach 0 to Mach 5, and potentially higher. The core innovation of SABRE technology lies in its ability to combine the functionalities of a jet engine and a rocket engine within a single, integrated system.
At lower speeds, up to approximately Mach 2.5, the SABRE engine operates in a mode similar to
As the vehicle accelerates beyond Mach 5, or if atmospheric air is unavailable, the engine transitions to
The development of SABREtekniikan is a significant undertaking in aerospace engineering, aiming to enable reusable, single-stage-to-orbit
