This 20,000HP AI-generated rocket engine took just two weeks to design and looks like HR Giger's first attempt at designing a trumpet

I've never looked at a rocket engine and thought «well that's dull», but this design makes all the others look positively pedestrian. That's because, rather than the traditional process of countless engineers spending months, even years manually engineering a model in programs like CAD, this one was designed in two weeks—thanks largely to AI.

Leap 71, a Dubai-based AI engineering company, says it created the design with Noyron, its Large Computational Engineering Model. The company says it was designed autonomously «without human intervention», before being 3D-printed in copper by German metal 3D-printing company AMCM, post-processed at the University of Sheffield, and then test fired.

Each new engine iteration generated by the AI model is said to take minutes, compared to the months of work put into a conventional rocket engine design. The engine uses cryogenic liquid oxygen (LOX) and kerosene as propellents, and the injector head features a «state-of-the-art coaxial swirler» to mix them.

Yep, that's the sort of description Wallace, of Wallace and Gromit fame, would use to describe his latest rocket design. A «coaxial swirler». What a time to be alive.

The engine is designed to produce 5 kN of thrust (equivalent to 500 kg/1120 lbs of lift mass or 20,000 horsepower), and Leap 71 says it would be suitable for the final «kick stage» of an orbital rocket.

The test firing took place at Airborne Engineering's facilities in Wescott, UK, and if you're the sort of person that likes to watch a rocket go off for giggles, boy do I have a video for you: 

Air-punching stuff, isn't it? Copper seems initially like an odd choice for a rocket engine given its low melting point, but apparently it enables «compact high-performance engines» when actively cooled. For reasons that, to my admittedly dull mind, remain unclear. Still, the more you know.
