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 program, 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.
Steve Nordlund, vice president of Boeing HorizonX, said:
“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.”
