The Invictus project is leveraging tech that the now-defunct British company Reaction Engines developed for a huge space plane called Skylon.

Reaction Engine's Synergetic Air-Breathing Rocket Engine (SABRE) is closer to reality with ESA and the UK Space Agency (UKSA) green lighting the preliminary design of the demonstrator engine core.

UK company Reaction Engines conducts a successful test of a key part of its Synergetic Air-Breathing Rocket Engine (SABRE), which could fly in space at Mach 25. CNN values your feedback 1.

U.K. aerospace manufacturer Reaction Engines, ... the Synergetic Air-Breathing Rocket Engine or SABRE. The SABRE is rather unique in that it can switch between two modes ...

The Synergetic Air-Breathing Rocket Engine (SABRE) engine is a hypersonic hybrid design that draws in air like a conventional jet while accelerating to speeds of up to Mach 5 (3,704 mph, 5,961 km ...

SABRE, which stands for Synergetic Air-Breathing Rocket Engine, is an air-breathing engine, which uses ultra-lightweight heat exchangers to cool very hot air streams – such as those encountered ...

In 2019, Reaction Engines reported that it reached a significant milestone in the development of its Synergetic Air Breathing Rocket Engine—known as SABRE—after it validated its precooler ...

Two Synergetic Air-Breathing Rocket Engines (SABRE) will power the Skylon space plane — a privately funded, single-stage-to-orbit concept vehicle that is 276 feet (84 meters) long. At take-off ...

Here is a look at the Synergetic Air-Breathing Rocket Engine (SABRE) developed by Reaction Engines Ltd over the last 20 years which could power a re-usable space plane.

They call it the greatest advance in propulsion since the jet engine; potentially revolutionizing hypersonic flight and dramatically reducing the cost of space access.

The SABRE air-breathing rocket engine is ready for a major round of testing in the next 18 months after passing a preliminary design review by the European Space Agency.
