Reaction Engines is a UK-based company formed in to design and develop the technologies needed for a new class of innovative hypersonic propulsion system – the Synergetic Air-Breathing Rocket Engine (SABRE). Reaction Engines has achieved a breakthrough in aerospace engine technology by developing ultra-lightweight heat exchangers. The heat exchangers stop engine components from overheating at high flight speeds. The heat exchanger technology has the potential to revolutionise what can be achieved with thermal management across a range of industries, from aerospace to motorsport, industrial processes, and the energy industry.
