Boeing has announced its investment in Reaction Engines Limited, a leader in advanced propulsion systems based in Oxfordshire, UK. Reaction Engines’ technology will contribute to the next generation of hypersonic flight and space access vehicles.

Breathing rockets

Reaction Engines is known for its Synergetic Air-Breathing Rocket Engine (SABRE), a hybrid engine blending jet and rocket technology that is capable of Mach 5 in air-breathing mode and Mach 25 in rocket mode for space flight. As part of the SABRE programme, Reaction Engines developed an ultra-lightweight heat exchanger that stops engine components from overheating at high speeds, thus improving access to hypersonic flight and space.

“As Reaction Engines unlocks advanced propulsion that could change the future of air and space travel, we expect to leverage their revolutionary technology to support Boeing’s pursuit of hypersonic flight,” said Steve Nordlund, vice president of Boeing HorizonX.

Boeing HorizonX invests in new ventures and startups. Its aim is to find unique business opportunities for Boeing’s aerospace technology through assessing aerospace industry disruption.

Reaction Engines

Founded by three propulsion engineers in 1989, Reaction Engines produces technical designs for advanced heat exchangers, air-breathing engines, and the vehicles they could power. These capabilities may lead to high-speed point-to-point transport that is cost-effective and sustainable.

Mark Thomas, CEO of Reaction Engines, said: “Boeing is a world-leader in many fields, bringing invaluable expertise in hypersonic research and space systems. I am thrilled and honoured that Boeing HorizonX has chosen Reaction Engines as its first UK investment. This is a very exciting step that will contribute to our efforts to develop a commercial technology business and accelerate opportunities to further the future of air and space travel through SABRE technology.”

Boeing HorizonX Ventures participated in this £26.5 million Series B funding round alongside Rolls-Royce Plc and BAE Systems.
