Test Facility 1 (TF1)

Work commenced in May 2017 to build a significant new UK test site. This facility at Westcott, Buckinghamshire, UK will enable Reaction Engines to test critical subsystems along with the testing of a SABRE™ engine core. This is the crucial step towards a SABRE powered flight test vehicle – a veritable Kitty Hawk moment for the 21st century.

The test facility will consist of a multi-purpose propulsion test stand designed to accommodate various test engine configurations, an assembly building, workshops, offices and control room. 

The test facility is located in the Westcott Venture Park, a location with a strong history of rocket propulsion research, having been used to test various UK rocket projects since 1946, including the Blue Streak and Black Arrow programmes. In 2016 the UK Space Agency selected Westcott as the UK’s National Space Propulsion Test Facility and the site is now home to a number of space propulsion and satellite technology companies.

Reaction Engines and Air Liquide have signed an agreement for the system to supply gases and liquids to the facility at Westcott. You can read more on this here.
