AI-designed, Monolithic Aerospike Engine Successfully Hot-fired
Showing how far AI engineering has come, a new aerospike engine burning oxygen and kerosene capable of 1,100 lb (5,000 N) of thrust has successfully been hot-fired for 11 seconds. It was designed from front to back using an advanced Large Computational Engineering Model.
Designing and developing advanced aerospace engines is generally a complicated affair taking years of modeling, testing, revision, prototyping, rinsing and repeating. With their ability to discern patterns, carry out complex analysis, create virtual prototypes, and run models thousands of times, engineering AIs are altering the aerospace industry in some surprising ways – provided, of course, they are properly programmed and trained.
Otherwise, it's garbage in, garbage out, which has been the Golden Rule of computers since they ran on radio valves and electromechanical relays.
the LEAP 71 aerospike in stages of firingLEAP 71
Dubai-based LEAP 71 is demonstrating what modern engineering AI can do by applying it to the problem of one of the more outré rocket engine designs – the aerospike.
Conventional rockets use the familiar bell to direct and expand the hot gases coming from the engine after passing through the Venturi nozzle. This design works very well, but it has one major disadvantage. The curve of the bell has to be custom designed to efficiently operate at a particular altitude, so a rocket that works very well on liftoff will work less well as it rises in the atmosphere and the air pressure decreases. This is why second- and third-stage rocket engines are different from those of the first stage.
Ideally, engineers want an engine that can adjust itself automatically to changes in air pressure. An aerospike does this by shaping the engine into a spike or plug with a curve like that of the inside of a rocket bell. As the combustion gases flow from the engine over the spike, the curve acts as one side of the bell and the surrounding air as the outside curve. As the air pressure changes, so does the shape of the virtual bell.

There have been a number of aerospike engines developed since the 1950s and one has actually gone airborne, but there's still a long way to go when it comes to turning a promising idea into a practical space engine.
LEAP 71's contribution to the effort is to apply its Noyron Large Computational Engineering Model to the problem. It's an AI programmed and trained by aerospace experts to take a given set of input parameters and use them to create a design that meets those parameters by inferring physical interactions of various factors, including thermal behaviors and projected performance.
The results of this are then fed back into the AI model to fine tune it as it presents computed performance parameters, the geometry of the engine, the parameters of the manufacturing process, and other details.

According to the company, Noyron was able to autonomously design the new aerospike in about three weeks. It was then fabricated as a solid block of copper using Selective Laser Melting industrial 3D printing technology before going to the test phase. On December 18th, 2024, it succeeded on the first test firing where it was subjected to gas temperatures of 3.500 °C (6,300 °F).
The exercise was part of a four-engines-in-four-days campaign by LEAP 71 at Airborne Engineering in Aylesbury, England.
"We were able to extend Noyron's physics to deal with the unique complexity of this engine type," said Josefine Lissner, CEO and Co-Founder of LEAP 71. "The spike is cooled by intricate cooling channels flooded by cryogenic oxygen, whereas the outside of the chamber is cooled by the kerosene fuel. I am very encouraged by the results of this test, as virtually everything on the engine was novel and untested. It's a great validation of our physics-driven approach to computational AI."

Machine Learning Predicts Aerospace Pressure Fluctuations
A recent study has examined how machine learning (ML) techniques can be used to predict wall pressure fluctuations on aerospace launchers during atmospheric ascent. These predictions address a critical issue in aerospace engineering: pressure variations that can cause surface vibrations and potentially damage payloads. By improving accuracy and efficiency in these predictions, the research aims to support safer and more effective aerospace vehicle designs.

Image Credit: Thierry Weber/Shutterstock.Com Understanding Pressure Fluctuations in Aerospace During launch, aerospace vehicles experience intense pressure fluctuations as they ascend through the atmosphere. These turbulent flows generate varying pressure loads on the vehicle's surfaces, which can lead to structural fatigue and damage over time. Traditionally, engineers have relied on wind tunnel testing and semi-empirical models to estimate these loads. While effective, these methods are time-consuming and expensive.
Improved predictive methods are essential for ensuring the structural integrity and performance of launch vehicles. Accurate forecasting can minimize risks during the design phase and enhance safety throughout the vehicle's lifecycle.
Research Approach and MethodologyIn this study, the researchers focused on predicting acoustic loads on the European Advanced Generation Vehicle (VEGA) launcher family during atmospheric flight. Their approach utilized data from wind tunnel tests performed on a scaled 1:30 model of the VEGA launcher, with pressure fluctuations recorded using 23 miniature sensors strategically placed on the vehicle's surface. The experiments were conducted in the T1500 transonic wind tunnel at the Swedish Defence Research Agency.
The team applied a variety of supervised ML algorithms to predict sound pressure levels (SPLs). These algorithms included:
The models relied on input parameters such as Mach number, angle of incidence, and sensor position. The dataset contained 36,708 observations recorded at 105 samples per second over 2.2 seconds. These observations spanned Mach numbers from 0.83 to 0.98 and angles of incidence ranging from 0° to 6°.
The performance of each model was evaluated using statistical metrics such as mean squared error (MSE), root mean squared error (RMSE), and correlation coefficient (R-squared). Sensitivity analyses were also conducted to determine how dataset size affected the accuracy of predictions.
Key Findings from the StudyThe study highlighted the effectiveness of ensemble methods, particularly the bagged tree approach, in predicting pressure fluctuations. This model consistently achieved the lowest RMSE values, outperforming other algorithms across all test conditions. Models such as ANNs, GPR, and SVMs exhibited higher error rates, likely due to their sensitivity to data distribution and noise.
Tree-based algorithms proved especially robust. Even when the training dataset size was reduced, RMSE values showed minimal variation, underscoring the stability of the bagged tree method. Importantly, the models demonstrated strong generalization capabilities, successfully predicting outcomes for unseen aerodynamic conditions—a critical requirement for real-world aerospace applications.
The study emphasized that ML-driven models can significantly reduce dependence on costly wind tunnel testing by offering reliable and efficient predictive solutions. This shift can improve safety and optimize the design and testing processes for aerospace vehicles.
Applications and Broader ImpactThe methodologies developed in this research have practical implications for aerospace engineering and beyond. Predictive ML models enable more precise forecasting of acoustic loads and structural responses during flight, reducing the need for extensive wind tunnel testing. These techniques can also extend to various aerospace vehicle designs, adapting to different geometries and flow conditions.
Beyond aerospace, these ML approaches hold promise for industries where pressure fluctuations and acoustic loads are critical. For example, automotive engineering and civil construction could benefit from similar predictive models, leading to stronger, more efficient designs.
Next Steps and Future ResearchThis research demonstrates the effectiveness of machine learning in predicting wall pressure fluctuations on aerospace launchers. The bagged tree algorithm emerged as the most reliable model, offering robust and accurate predictions across a range of test conditions.
Future work should focus on validating these models for diverse geometries and aerodynamic environments, addressing the complexities of turbulent flows. Integrating traditional methods with ML approaches may further enhance prediction accuracy and expand the applicability of these tools. Ultimately, this research provides a framework for safer and more efficient aerospace designs while reducing costs and improving reliability.
