Reaction Engines Ltd and Rolls-Royce plc have formed a brand new strategic partnership agreement to build up high-speed aircraft propulsion systems and explore applications for Reaction Engines’ thermal management technology within civil and defence aerospace gas turbine engines and hybrid-electric systems.

“We've been working closely with Reaction Engines for the past two years, including exploring the potential of high-Mach systems for defence applications, and I am delighted that we are able to strengthen that relationship,” said Mark Thompson, Director of Global Strategy & Business Development, Rolls-Royce.

“This partnership follows our recent announcements with Boom Supersonic and Virgin Galactic.”

“Reaction Engines’ thermal management skills, added to our suite of existing technologies and capabilities, will further assist us as we explore opportunities in supersonic and hypersonic aviation,” Thompson added.

“Building on our many decades of innovation, we'll also explore the use of Reaction Engines’ technology inside our aerospace gas turbines and its potential application in future hybrid-electric propulsion systems, as we turn to make flying ever more efficient and sustainable.”

Additionally, Rolls-Royce is making a further investment in Reaction Engines included in a wider funding round. The 2 companies have been working together since 2021, including around the first phase of a UK Ministry of Defence contract to undertake design studies, research, development, analysis and experimentation associated with high-Mach advanced propulsion systems.

“This strategic partnership is about developing market ready applications for Reaction Engines’ technology in next-gen engines and is a significant step forward for our technology commercialisation plans,” said Mark Thomas, Chief Executive of Reaction Engines.

“Our proprietary heat exchanger technology delivers incredible heat transfer capabilities at extremely low weight and a compact size. We look forward to expanding our international collaboration with Rolls-Royce, a worldwide leader in power systems, to create to market a range of applications that will transform the performance and efficiency of aircraft engines, enable high-speed – supersonic and hypersonic – flight and offer the drive towards more sustainable aviation through new technologies.”
