The Biggest Breakthrough in Propulsion Since the Jet Engine




Reaction Engines Ltd. can announce today the biggest breakthrough in aerospace propulsion technology since the invention of the jet engine. Critical tests have been successfully completed on the key technology for SABRE, an engine which will enable aircraft to reach the opposite side of the world in under 4 hours, or to fly directly into orbit and return in a single stage, taking off and landing on a runway.

SABRE, an air-breathing rocket engine, utilises both jet turbine and rocket technology. Its innovative pre-cooler technology is designed to cool the incoming airstream from over 1,000ËšC to minus 150ËšC in less than 1/100th of a second (six times faster than the blink of an eye) without blocking with frost. The recent tests have proven the cooling technology to be frost-free at the crucial low temperature of -150ËšC.

The European Space Agency (ESA) has evaluated the SABRE engine's pre-cooler heat exchanger on behalf of the UK Space Agency, and has given official validation to the test results:
