ANSYS Case Study

Aircraft Takeoffs Get a Big Lift

Predicting complex high-lift aerodynamics

For an airline, one of the most costly parts of its business is takeoff. That's because next to labor, airlines spend the most on jet fuel. Planes use the most fuel — and, consequently, emit the most harmful emissions — during takeoff.

An aircraft design component called a "high-lift device" can help make planes more fuel efficient. But modeling the air flow critical to the design of a high-lift design isn’t simple, and the simulation process is computationally intensive. It requires robust and accurate software to model the complex physics.

Cray and ANSYS tackled the challenge, working together to accurately predict high-lift aerodynamics in two test cases. The results will allow airlines to conserve fuel and cut back on environmentally harmful emissions.

Here’s what they used:

ANSYS® Fluent® CFD XE software took advantage of multiple cores

Cray’s XC™ series supercomputer maximized performance

The XC system’s Aries™ network enabled effective scaling


The results were validated with experimental results from JAXA’s Low Speed Wind Tunnel.
