SABRE - Synergetic Air Breathing Rocket Engine - is a new class of engine for propelling both high speed aircraft and spacecraft. SABRE engines are unique in delivering the fuel efficiency of a jet engine with the power and high speed ability of a rocket.
Unlike jet engines, which are only capable of powering a vehicle up to Mach 3, three times the speed of sound, SABRE engines are capable of Mach 5.4 in air-breathing mode, and Mach 25 in rocket mode for space flight. They are simply going to revolutionise the way we travel around the globe, and into orbit. Like jet engines, SABRE can be scaled in size to provide difference levels of thrust for different applications which is crucial to our success - it's going to enable a whole generation of air and space vehicles.
There are three core building blocks to the SABRE engine, the pre-cooler, the engine core and the thrust chamber. Each of these systems can be developed and validated using ground based demonstrations which saves cost and time relative to flight test, a design feature that benefitted the development of the propeller and jet engine, We plan to demonstrate each of these independently over the next four years, beginning with a high temperature test of the pre cooler in 2017.
We’re about to start building a significant new UK test site to test critical subsystems and aim to test a fully integrated engine core in 2020. This is the crucial step towards a SABRE powered flight test vehicle – a veritable Kitty Hawk moment for the 21st century. We’re already working with partners to lay the groundwork for the first SABRE powered vehicles that will follow the SABRE ground and flight test programme.
We’re developing a suite of aerospace technologies for SABRE. Our core capabilities are in the development, manufacture and testing of ultra-lightweight heat exchangers and propulsion systems. The range of technologies which enable high speed air and space vehicles are also applicable to many other thermal, power and propulsion systems. Our heat exchanger technology has the potential to revolutionise the way we approach thermal management across a range of industries, from aerospace to motorsport, industrial processes, and oil & gas.

SABRE engines are fast – they can be used for air travel at over five times the speed of sound or to power reusable space launch vehicles. SABRE class engines can power aircraft capable of flying from London to Australia in four and half hours or spaceplanes that take off into orbit from a runway before returning to base and doing it all over again. Read on to find out more about the unique capabilities that SABRE unlocks for a wide-variety of exciting vehicles.Read More
