Unseen—for the most part, unless rendered visible by dust or contrails—and always unwelcome, wake turbulence causes flight-path disruption at best, and fatal accidents when encountered at its worst. Pilots do what they can to avoid it, especially when on takeoff or landing, and controllers are tasked with helping us to steer clear. Still, we’re not always successful, and the price is paid in bent metal and lives lost.
Purdue University’s New Turbulence Model Predicts Complex Scenarios
Key Takeaways:
- Wake turbulence is a significant aviation hazard, difficult to avoid due to the complex and computationally intensive models required for its prediction.
- Purdue University researchers have developed a new "Coherent-vorticity-Preserving (CvP) Large-Eddy Simulation (LES)" model.
- This novel model drastically reduces the computing power needed (by 10 to 100 times) to simulate complex vortex collisions, accelerating aircraft design.
- The improved modeling has diverse applications, from designing safer aircraft with reduced wake turbulence to advancing other vehicle and weapons systems.
