U.S. Air Force to Evaluate British Firm’s Spaceship Engine
Technology May Offer Unique Performance and Vehicle Integration Advantages
LONDON, U.K. — Reaction Engines Ltd has announced that it has entered into a Cooperative Research and Development Agreement (‘CRADA’) with the Air Force Research Laboratory’s Aerospace Systems Directorate (AFRL/RQ).
The CRADA provides a framework to assess the performance, applications and development paths for REL’s SABRE air-breathing rocket engine, a new class of aerospace engine designed for low cost, responsive space access and high speed atmospheric flight. This CRADA is the first U.S. government formal relationship with Reaction Engines Ltd and will be used to inform U.S. government stakeholders about the SABRE engine’s potential for hypersonic vehicle applications.

Reaction Engines has developed ultra-lightweight air heat exchanger technology that can transfer the same amount of heat generated by an electricity power station (450MW) using equipment that weighs less than a standard car and can cool air from 1,000°C (1832°F) to minus 150°C (-238°F) in 1/100th second whilst preventing the formation of ice at sub-zero temperatures.
Combined with unique thermodynamic cycles, Reaction Engines’ heat exchangers enable a new aerospace engine called SABRE that can fly at Mach 5.5 in the atmosphere (twice as fast as a jet engine) and then subtly transition to a rocket mode of operation allowing spaceflight at up to orbital velocity, or Mach 25 (7.5 kilometres per second). The viability of the SABRE engine has been independently validated by the European Space Agency during a review undertaken at the request of the UK government.
