Unlocking the future of space access and hypersonic flight.

Making beyond possible.

Flying faster. Going further. Making giant leaps in understanding.

The development of our innovative SABRE engine is enabling us to go beyond the limits of flight both within and outside the atmosphere. Every breakthrough is making space and hypersonic travel more efficient, more accessible, more possible.

But that’s only the beginning. We’re also creating pioneering applied technologies that have the potential to change the face of a wide range of commercial industries – from aerospace and automotive to energy.

Our innovative approach brings together brilliantly curious minds, leading edge technology and a passion to reimagine what’s possible.

Join us on our journey to the future.

Making beyond possible.

The sky’s no longer the limit. A truly versatile propulsion system – SABRE is an air-breathing rocket engine that can propel an aircraft from zero to five times the speed of sound in the atmosphere and 25 times the speed of sound for space access. Highly scalable, this pioneering breakthrough boasts a huge range of operation with the potential to redefine the world of powered flight.

Main Nozzle

Operates in both the atmosphere and in space, reducing weight and complexity

Rocket Engine

Provides thrust to power the engine for space access during rocket mode

Ramjet System

Improves overall engine efficiency by using surplus air to generate extra thrust

Air Compressor

Driven by the energy absorbed in the precooler, enabling runway start and takeoff

Supersonic Intake

Captures and slows the incoming air into the engine and can operate at speeds in excess of Mach 5 before closing for rocket mode

Precooler

Rapidly cools the incoming air (1,000°C to ambient) enabling SABRE to operate at higher speeds than existing engines

Engine Core

Powers SABRE during air-breathing flight. Heat absorbed by the precooler is recycled to power the engine, significantly reducing fuel consumption

Nacelle

Advanced materials designed to withstand extreme temperature conditions

SABRE technology can operate in both air-breathing and rocket modes

Precooler validated at hypersonic heat conditions

Mach 5 for hypersonic flight

Mach 25 for space access

Scalable for multiple applications

SABRE The engine that changes everything.

A key component in the development of our ground-breaking SABRE engine – our precooler technology is already transforming what’s possible in the world of heat management.

Combining thousands of thin-walled tubes to provide optimum surface-area-to-weight ratio, each tube is joined to an inlet and outlet manifold to allow coolant to be injected and removed for an extremely efficient and effective cooling process. We are world-leading experts in the development of heat exchanger manufacturing, bonding thousands of joints in a single operation, with zero leakage.

From over 1,000 degrees Celsius to ambient. In the blink of an eye.

Precooler technology proven at Mach 5 speeds

In October 2019, our HTX test programme carried out a ground-level demonstration of the precooler at Mach 5 airflow temperatures. Proving the potential of this innovation at five times the speed of sound marks a significant milestone in the development of SABRE – paving the way for a revolution in hypersonic flight, space access and a wide-array of applied technologies.

How it all works.

Powerful Injection

Coolant is injected and removed via inlet and outlet manifolds connected to each cooling tube.

Seamless Bonding

In a world first – our expertise allows us to bond thousands of joints in a single operation. With zero leakage.

Cylindrical Cooling

By bringing together thousands of thin-walled tubes in a cylindrical formation, we create optimum surface-area-to-weight ratio.

There’s really never been a better time to join us on the journey. Reaction Engines’ innovative technology has the backing of some of the most influential names in aerospace and finance. We’re supported by the UK Government, UK Space Agency and European Space Agency and our US team are working with US Government and industry partners.

Recent investment is supporting key elements of SABRE and the continuation of the ground test development programme – allowing us to accelerate our commercialisation plans for heat exchange technologies.
