The UK aerospace company Reaction Engine Limited was founded in 1989 for the express purpose of creating engines that would lead to spaceplanes capable of horizontal take-off and landing (HOTOL). With support from the ESA, these efforts have resulted in the Synergetic Air-Breathing Rocket Engine (SABRE). Once complete, this system will combine elements of jet and rocket propulsion to achieve hypersonic speeds (Mach 5 to Mach 25).
Recently, Reaction Engines passed a major milestone with the development of their SABRE engine. As the company announced earlier this week (on Tues. Oct. 22nd), their engineers conducted a successful test of a vital component – the engine’s heat exchange element (aka. precooler). What’s more, the test involved airflow temperatures equivalent to speeds of Mach 5, which is in the hypersonic range.Continue reading “Skylon’s SABRE Engine Passes a Big Test”
