Boeing and Rolls-Royce Invest in a New Hybrid Rocket Engine

The best features of a jet engine and rocket engine combined into one design.

The U.K. could soon get its own next-gen rocket engine, thanks to a partnership between Boeing and Rolls-Royce. The two companies are investing in a new type of jet engine/rocket engine hybrid that could take payloads to space much more efficiently than any current rocket.

The rocket engine in question is being developed by British company Reaction Engines Limited. Boeing and Rolls-Royce have invested a total of nearly $38 million in this company.

REL seeks to build a type of rocket engine that also functions as a hypersonic jet engine. The goal is that the jet engine could reach Mach 5.5 before switching to rocket fuel for the remaining journey into space.

This hybrid engine design offers numerous hypothetical advantages, but the biggest one is fuel efficiency. Using its jet capabilities while in the atmosphere ultimately means the whole trip requires less rocket fuel. It's the same general idea behind the enormous Stratolaunch aircraft that would use a huge plane to carry rockets into the sky and launch them from on high, except all built into a single engine.

I read about this in Aviation Week a while back. It is tech that has been in development for a very long time but maybe now we are getting to the point we can actually build it.

I would share the Aviation Week article but they are stingy and have pay walls lol.
