Key Takeaways:

NASA researchers are using the Pleiades supercomputer to model turbofan engine aerodynamics and acoustics, aiming to make airplane engines quieter.
The project seeks to develop faster and cheaper simulation software for designing more fuel-efficient, lower-emission engines without increasing noise levels.
This research utilizes advanced techniques, such as a "sliding mesh," to reduce the high computational cost and complexity of detailed engine noise simulations.

In the ongoing quest to make airplane engines quieter, a team of NASA researchers is turning to Pleiades, one of the world’s most powerful supercomputers.

Engineers and researchers at NASA’s Ames Research Center at Moffett Field (KNUQ) in California are modeling aerodynamic and acoustic fields around turbofan engines in order to develop software that can model engine configurations faster and cheaper. Project results will be compared to data collected at the Low Speed Anechoic Wind Tunnel at NASA’s Glenn Research Center in Cleveland to determine how the simulation techniques work with the software framework.
