The world of aviation is on the cusp of a revolutionary transformation, driven by the power of supercomputing and artificial intelligence (AI). At the forefront of this change is the Aurora supercomputer, housed at the Argonne National Laboratory. As one of the world’s first exascale supercomputers, Aurora is capable of performing over a quintillion calculations per second, providing unprecedented computational power to researchers. This cutting-edge technology is being harnessed to refine the design of next-generation airplanes, promising significant improvements in efficiency and performance.
The Role of Aurora in Airplane Design
The Argonne National Laboratory, part of the U.S. Department of Energy, is leveraging Aurora’s capabilities to explore novel approaches to airplane design. A team from the University of Colorado Boulder is utilizing Aurora’s exascale power to analyze the airflow around commercial aircraft. The goal is to derive insights that will inform the design of more efficient airplanes. According to Kenneth Jansen, a professor of aerospace engineering, the team can now run larger and more complex simulations than ever before. These simulations improve predictive models by capturing the intricate flow physics around critical aircraft components like the vertical tail and rudder assembly.
By understanding and optimizing these flow dynamics, researchers aim to reduce drag, improve fuel efficiency, and lower emissions. The ability to perform such detailed simulations marks a significant advancement in aerospace engineering, potentially leading to smaller, more efficient aircraft designs.
Why Airflow Matters
Airplanes are often designed with larger vertical tails than necessary to handle worst-case scenarios such as taking off in a crosswind with only one engine operational. The research team believes that by studying airflow physics more thoroughly, they can design smaller tails that remain effective under such conditions. To achieve this, they employ a tool known as HONEE to conduct detailed airflow simulations. These simulations model the complex and chaotic behavior of turbulent air. The resulting high-quality data trains AI models called subgrid stress (SGS) models.
SGS models are crucial because they predict the impacts of tiny turbulent air movements that are not visible in lower-resolution simulations. This precision is essential for accurate airflow predictions and, ultimately, for optimizing aircraft design.
Understanding Turbulence
Traditional methods of studying turbulence rely heavily on extensive datasets and slow offline analysis. However, the team’s innovative approach integrates machine learning directly with simulation processes. This method, known as “online machine learning,” eliminates the need for storing vast amounts of data. Instead, simulations generate training data concurrently with the training process itself. This real-time analysis enables researchers to scrutinize simulation fields dynamically and extract valuable insights as they emerge.
By employing machine learning, scientists can enhance and extend existing turbulence models, uncovering new modeling behaviors. This capability allows for the development of predictive models that identify the behavior of turbulent air, facilitating the testing of new concepts for real-time flow control and evaluating how smaller tail designs perform under extreme conditions.
Leveraging Advanced Tools
The research team combines Aurora’s exascale power with advanced tools to accelerate aircraft design. Key tools include SmartSim for real-time data streaming and in-node training, along with PETSc for scalable numerical calculations. This integrated approach streamlines the design process, combining simulation and machine learning to reduce the need for costly physical testing. By uniting these powerful tools, researchers can achieve faster, more efficient aircraft designs, paving the way for a new era of aviation technology.
This technological synergy highlights the potential for supercomputing and AI to revolutionize industries beyond aerospace. As these tools continue to evolve, they promise to bring about transformative changes across various fields, pushing the boundaries of what’s possible.
As we stand on the brink of this exciting transformation in aviation, the potential for innovation seems limitless. The integration of supercomputing and AI in aircraft design not only promises to enhance efficiency but also to redefine safety and performance standards. With such rapid advancements, the question arises: How will these technologies reshape the future of air travel and beyond?
