Simulating Aircraft Icing

Icing on aircraft surfaces, appendages, and sensors, as well as the impact of icing on aircraft engines, are safety-critical aspects of aircraft design that impact the whole supply chain. Achieving regulatory certification is a complex and time-consuming process involving simulation models, icing tunnels and flight testing. Recent regulatory changes and industry focus around high altitude ice crystals and supercooled large droplets (SLD) have further challenged the design process and the time to market for new aircraft and technology.

ANSYS provides a unique combination of advanced computational fluid dynamics and icing simulation expertise in a common working environment. The solution is 3-D, so it captures real-world behavior, provides the most efficient simulation workflow available and has an extensive database of industry validation. In addition, the simulation outputs are designed to comply with the FAA’s Appendices C, D and O.

ANSYS icing simulation enables companies and engineers to develop products faster, test designs earlier in the development cycle, reduce the number of physical prototypes and produce a better solution than would be possible using traditional design methods.
