ABINGDON, England (Reaction Engines PR) — Reaction Engines has successfully tested its innovative precooler at airflow temperature conditions representing Mach 5, or five times the speed of sound, marking a significant milestone in the development of its SABRE™ engine and paving the way for a revolution in hypersonic flight and space access.

The precooler heat exchanger is a vital component of Reaction Engines’ revolutionary SABRE air-breathing rocket engine and is an enabling technology for other precooled propulsion systems and a range of commercial applications.
