In June 2024, Dubai based artificial intelligence engineering company LEAP 71 made history in the aerospace manufacturing industry - its developed large-scale computational engineering model Noyron completed the design of a rocket engine in just two weeks and successfully ignited and tested it. This breakthrough not only demonstrates the enormous potential of AI technology in the field of complex engineering design, but also heralds an efficiency revolution in the aerospace manufacturing industry.
1. Technological breakthroughs and innovation paths of AI design engines
1.1 Noyron: The Intelligent Transition from Physical Laws to Engineering Design
Noyron developed by LEAP 71 is a revolutionary large-scale computational engineering model that encodes physical knowledge such as thermal models and manufacturing process rules into a unified framework. Unlike traditional design methods that rely on human engineer experience, Noyron is able to autonomously generate complete engineering designs, including geometric shapes, manufacturing process parameters, and performance predictions, without the need for manual CAD input throughout the entire process.
During the design process, Noyron demonstrated astonishing efficiency. From parameter settings to generating 3D printable engineering files, it only takes 15 minutes, while completing the entire engine design and manufacturing process only takes two weeks. In contrast, traditional rocket engine design takes months or even years, and each iteration also takes weeks. This efficiency improvement has reached a level of tens of times.
1.2 3D Printing Technology: Seamless Integration from Design to Manufacturing
LEAP 71 has partnered with German metal 3D printing company Aconity3D to directly manufacture AI designed engines using L-PBF technology. This integrated manufacturing method uses high-performance aerospace copper alloy (CuCrZr) to 3D print the engine as a single integral component.
The application of 3D printing technology has brought multiple advantages. Firstly, it is capable of manufacturing complex internal structures that traditional processes cannot achieve, such as Noyron's engine designed with intricate cooling channels that are difficult for humans to manually process. Secondly, 3D printing has shortened manufacturing time by 2-10 times and reduced costs by over 50%. For example, a complex 600mm injector head can be printed in just 4 days.
1.3 Autonomous Learning and Evolution: The Continuous Optimization Capability of AI
Another revolutionary feature of Noyron is its ability for autonomous learning and evolution. After each test, LEAP 71 will provide feedback on the collected data to Noyron for optimizing the design of the next generation engine. The co-founder of LEAP 71 stated that they have
On average, a new engine was ignited and tested every four weeks for 18 months, with differences in design each time, to enrich Noyron's real data feedback.
This kind of '; Design Print Test Learn; The closed-loop mode enables AI to continuously evolve and improve. The goal of LEAP 71 is to have Noyron evolve every three weeks, achieving infinite acceleration in its design. This model has completely changed the traditional engineering design paradigm, transforming the development of rocket engines from; Experience driven "; Turning "; Data+Model Driven;.
2. Revolutionary improvement of production efficiency
2.1 Exponential growth in design efficiency
The efficiency improvement brought by AI technology in the field of rocket engine design is disruptive. According to LEAP 71 data, the entire process from final specification determination to manufacturing completion has been shortened from traditional months or even years to less than two weeks. The iterative design of each new engine only takes a few minutes, while traditional methods require several weeks.
This efficiency improvement has been validated in specific projects. In the simulation calculation of the Blue Arrow rocket engine, the traditional method requires 5000 hours (about 6 months) using 2000 Intel CPUs, while the AI driven DeepFlame method only takes 5000 seconds (about 1.4 hours), increasing efficiency by 3600 times. In the single step simulation, the efficiency was improved by 3600 times from 1 hour to 1 second.
2.2 Significant reduction in manufacturing costs
The combination of AI and 3D printing technology not only improves speed, but also brings significant cost reductions. According to NASA's research, metal additive manufacturing can reduce the cost of rocket engines by over 50%. In specific cases, the manufacturing cost of rocket combustion chambers decreased from the traditional $310000 to $125000, a reduction of 60%.
The case of SpaceX is even more remarkable. The cost of its Raptor engine has dropped from $2 million for the first generation to $250000 for the third generation, a decrease of 87.5%. It is expected that the cost of Raptor 4 will further decrease to $250000, which is only 25% of the first generation. This cost reduction is mainly achieved through AI driven simulation testing, reducing the cost of physical prototype testing by up to 30%.
