This rocket engine wasn’t sketched, tuned, or optimized by human hands. It was designed entirely by AI, starting from the raw laws of physics. What you’re looking at is LEAP 71’s NEURON 20 kN aerospike rocket engine, featured by YouTuber Intezga — and it represents a massive shift in how propulsion systems are built. Instead of engineers drawing CAD models, LEAP 71 uses a computational AI system that encodes: • thermodynamics • fluid dynamics • combustion physics • material limits • manufacturing constraints You give the AI a performance target — and it generates a complete engine geometry on its own. The entire engine is 3D-printed as a single copper piece, enabling insanely complex internal cooling channels that traditional machining simply can’t make. Inside the chamber, temperatures exceed 3,000°C, while liquid oxygen at −183°C flows through the walls for regenerative cooling — so cold that frost forms on the outside while the engine is firing. That green flame during testin...
