Air-breathing rocket engines: the future of space flight

Reusable vehicles are vital to make access to space more affordable, but conventional rocket engines have their limits, Oliver Nailard writes for Physics World.

OXFORDSHIRE, U.K. - The pursuit, exploration and utilization of the space environment can be misinterpreted as a luxury. History portrays space as an exclusive domain for global powers looking to demonstrate their prowess through technological marvels, or the stage for far-off exploration and scientific endeavour with little impact on daily life. However, the benefits of space are already woven into our everyday routines and provide utilities and resources on which the society has grown dependent. If these were suddenly to disappear and the world were to experience just “a day without space”, the consequences would be evident to all, Oliver Nailard writes for Physics WorldContinue reading original article.

The Intelligent Aerospace take:

October 16, 2020 -Last October, Reaction Engines successfully tested its precooler at airflow temperature conditions representing Mach 5, or five times the speed of sound, marking a significant milestone in the development of its Synergetic Air Breathing Rocket Engine (SABRE) and paving the way faster hypersonic flight as well as space access. The SABRE engine, Reaction Engines says, is capable of Mach 5 in the atmosphere and Mach 25 to access space.
