Boeing invests in UK-based hypersonic propulsion tech developer Reaction Engines via HorizonX

Boeing has invested in Reaction Engines through its ventures arm to assist the U.K.-based company in its efforts to develop a hypersonic propulsion technology.

Reaction Engines has developed a heat exchanger that works to prevent overheating of engine components at high speeds as part of its Synergetic Air-Breathing Rocket Engine technology program, Boeing said Wednesday.

Boeing HorizonX Ventures joined BAE Systems and Rolls-Royce in the Series B funding round that raised $37.3 million for Reaction Engines.

Steve Nordlund, vice president of Boeing HorizonX, said the company will leverage Reaction Engines’ technology to back its hypersonic flight pursuit.

“I am thrilled and honored that Boeing HorizonX has chosen Reaction Engines as its first U.K. 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,” said Mark Thomas, CEO of Reaction Engines.
