Reaction Engines

Reaction Engines is a UK-based company formed in 1989 to design and develop the technologies needed for a new class of innovative hypersonic propulsion system – the Synergetic Air-Breathing Rocket Engine (SABRE).

The company has achieved a breakthrough in aerospace engine technology by developing ultra-lightweight heat exchangers. Developed for its high-speed SABRE engines, the heat exchangers stop engine components from overheating at high flight speeds.

SABRE class engines will enable aircraft to fly over five times the speed of sound in the atmosphere and allow space launch vehicles to be built that will radically improve the affordability and responsiveness of access to space.

Reaction Engines' heat exchanger technology has the potential to revolutionise what can be achieved with thermal management across a range of industries, from aerospace to motorsport, industrial processes, and the energy industry.

In addition to the SABRE development programme, Reaction Engines offers a unique and extensive range of capabilities, from propulsion systems and advanced heat exchanger design and development, through to advanced manufacturing and precision machining.

The company has begun partnering with aerospace suppliers to deliver a ground-based SABRE demonstrator engine. There’s never been a better time to join Reaction Engines on the journey.
