Honeywell, Reaction Engines to Collaborate on Sustainable Thermal Management Technologies

Honeywell, Reaction Engines to Collaborate on Sustainable Thermal Management Technologies

  • Advanced thermal management technologies will lower fuel consumption and reduce aircraft emissions for all fuel types 

PHOENIX, July 24, 2022 — Honeywell (NASDAQ: HON) and Reaction Engines Limited, a British aerospace company, have signed a memorandum of understanding to collaborate on the development of thermal management technologies as a critical enabler to reduce aircraft emissions, regardless of the fuel type used in the aircraft. 

Honeywell and Reaction Engines will adapt the unique microtube heat exchanger technology from Reaction Engines and apply it across a broad range of Honeywell systems for sustainable aviation thermal management solutions. Benefits of this collaboration are immediately apparent: Reaction Engines develops unique heat exchange technology that can reduce weight by more than 30%, which translates to less fuel consumption and longer range or higher capacity of aircraft.  

The potential for this technology is wide-ranging across all segments of the aerospace industry. Heat exchangers are important components of many of the aircraft mechanical systems that Honeywell manufactures. Today, Honeywell heat exchangers are being used on various platforms, from extremely compact spacecrafts to large, wide-body airliners. They are critical in assisting aerospace heating and cooling and have a direct impact on aircraft fuel efficiency. Future generations of aircraft powered by sustainable fuels will require much more efficient and lightweight thermal management than what is available today. Advancements of this technology will help aircraft manufacturers deliver on sustainability commitments and meet government sustainability regulations while increasing operational efficiencies.  

“Our transformative thermal management technology provides a step change in performance, efficiency and sustainability and is a genuine enabler of zero-emissions aerospace. Decarbonizing the aerospace industry is one of the most significant challenges facing humankind today, and we are committed to creating solutions that promote sustainability and clean aviation. We are delighted to collaborate with Honeywell on groundbreaking projects that will accelerate the road map to net-zero aviation,” said Tom Burvill, director, Applied Technologies, Reaction Engines.

“At Honeywell, we are proud to work on projects that have the potential to improve the future of aviation,” said Michelle Drage, vice president, Air and Thermal Systems, Honeywell Aerospace. “Building on our relationship with Reaction Engines provides an exciting opportunity to apply our combined expertise on new thermal management and heat exchange technology to provide increased efficiency for our customers and to make an impact on global sustainability goals.” 

Thermal management is instrumental to the development of aircraft with minimal carbon emissions. It plays a significant role in research activity that Honeywell has committed to through the Clean Aviation Joint Undertaking, the European Union’s leading research and innovation program for transforming aviation toward a sustainable and climate-neutral future.

About Reaction Engines

Reaction Engines is a privately held technology company pioneering space access and sustainable technologies.  The Company is based in Culham, Oxfordshire, U.K. and Denver, Colorado, U.S. and employs over 200 staff across its sites.

Reaction Engines has been at the forefront of engineering innovation for over 30 years, principally developing SABRE, a revolutionary new class of aerospace propulsion. SABRE enables us to go beyond the limits of flight both within and outside the atmosphere. Making space and high-speed travel more efficient, more accessible, more possible. 

The Company is supported by the U.K. Space Agency and European Space Agency, and the U.S. team is working with DARPA, U.S. Air Force and leading Industry Partners. In addition to private capital funding, in recent years Reaction Engines has received investment from BAE Systems, Rolls-Royce and Boeing HorizonX.

Developed for SABRE, our proprietary precooler technology is truly transformational, delivering world-leading heat transfer capabilities across diverse industries to improve performance in motorsport, convert waste heat into renewable electricity and support more sustainable aviation.

Our revolutionary thermal management solutions have the potential to elevate life on Earth.
