REACTION ENGINES & Rolls Royce team up

I am thrilled beyond words that they have been taken into the RR fold and getting the time and attention that their (already legendary) precooler & engine technology deserves.

This will give them an immense avenue of potential outside of the classified military realm. Who knows? Maybe they will be the defacto team to have aboard for all high speed assets developed over the next 10 years. I certainly can see it happening. Fingers crossed.

Reaction Engines is the company responsible for SABRE (Synergetic Air-Breathing Rocket Engine) which they describe as a new class of aerospace propulsion with the potential to provide air-breathing thrust from standstill on the runway to speeds above Mach 5 in the atmosphere. The scalability of SABRE allows for multiple applications whilst delivering the fuel efficiency of a jet engine with the high-speed capability of a rocket.

Reaction Engines’ proprietary pre-cooler technology is key to SABRE. As previously reported in The Engineer, the pre-cooler heat exchanger consists of thousands of thin-walled tubes through which coolant is passed, giving a high surface-to-weight ratio that quenches extreme airflow temperatures in a fraction of a second. This means that SABRE’s actual jet engine element receives the cool ambient air it needs to function efficiently.
