TL;DW: Leap71, founded by software engineer Lean and aerospace engineer Josephine, has developed the Neuron algorithm that autonomously designs functional rocket engines. Unlike traditional AI, Neuron derives designs from fundamental physics principles, such as combustion and heat transfer, enabling it to create complex structures like monolithic aerospike engines without human iteration. The company tested a 20kN aerospike engine using liquid oxygen and kerosene propellants, featuring regenerative cooling with both oxidizer and fuel flowing through engine walls to withstand over 3,000°C combustion temperatures.
The engine, 3D-printed in copper by Econity 3D as a single part, demonstrates advanced manufacturing techniques that eliminate assembly risks seen in historical designs like the Saturn V's F-1 engine. Tests revealed efficient combustion but minor cooling issues in the spike, causing copper erosion and green flames; data from these trials will refine future iterations. Leap71's approach evolves designs organically by incorporating test data, accelerating rocket technology development and potentially transforming the industry with scalable, high-performance engines.
This innovation highlights the shift toward algorithmic engineering, reducing design time and costs while enabling exotic configurations like aerospikes that adapt to varying atmospheric pressures. By focusing on physics-based rules rather than pattern-matching, Neuron promises broader applications beyond rocketry, from automotive to aerospace components.
Key Takeaways:
• Leap71's Neuron algorithm designs rocket engines from physics principles, not example-based learning.
• The tested 20kN aerospike engine uses liquid oxygen and kerosene with dual regenerative cooling.
• Engine is 3D-printed in copper as one monolithic part, minimizing assembly failures.
• Tests showed successful ignition and thrust, but minor cooling issues led to copper erosion.
• Data from tests feeds back into Neuron to improve subsequent designs organically.
• Aerospike design adapts to pressure changes, outperforming traditional bell nozzles in versatility.
• Propellant choice balances cryogenic challenges with kerosene's thermal stability for cooling.
