Its major focus was the development of SABRE (Synergetic Air Breathing Rocket Engine), said to combine the fuel efficiency of a jet engine with the power and high speed offered by rockets.

Powered by the hypersonic SABRE engine it operates like a jet engine at low altitude and more like a conventional rocket at ...

The dream of flying at five times the speed of sound still faces huge obstacles, ranging from technical to environmental to ...

The Company is a privately-owned aerospace engineering research company, founded in 1989. It has been focused on the development of the SABRE rocket engine for over 30 years, alongside contributing to ...

An Oxford University spin-out, Reaction has been developing its pioneering hypersonic synergetic air-breathing rocket engine (SABRE) for the last 35 years. It foresaw widespread applications for ...

The Sabre air-breathing rocket engine is designed to drive space planes to orbit and take airliners around the world in just a few hours. To work, it needs to manage very high temperature airflows ...

Founded in 1989, Reaction’s Sabre technology — short for Synergetic Air Breathing Rocket Engine — was designed to combine the fuel efficiency of a jet engine with the power of a rocket.

The Sabre engine is part jet, part rocket, and relies on a novel pre-cooler heat-exchanger technology. This pre-cooler system will begin a new phase of testing in the next month or so in Colorado ...
