>Air-breathing engine precooler achieves record-breaking Mach 5 performance
>UK company Reaction Engines has tested its innovative precooler at airflow temperature conditions equivalent to Mach 5, or five times the speed of sound. This achievement marks a significant milestone in its ESA-supported development of the air-breathing SABRE engine, paving the way for a revolution in space access and hypersonic flight.
>This ground-based test achieved the highest temperature objective of the company’s ‘HTX’ hot heat exchanger test programme: it successfully quenched airflow temperatures in excess of 1000 °C in less than 1/20th of a second.
