AIRA - Aircraft Icing Research Alliance

3-D Ice Accretion Code Workshop 2010

The 2010 3-D Ice Accretion Code Workshop was held on August 4, 2010, as part of the AIAA Atmospheric and Space Environments Conference in Toronto, Ontario, Canada.

This workshop was organized for the following reasons:

  • Review current issues for acceptance of 3-D ice accretion simulation tools by regulatory authorities for aircraft icing certification.
  • Discuss current status and needs for standards, guidance, and acceptable practices for 3-D ice accretion simulation tools for aircraft icing design and certification
  • Develop validation strategies for a publicly available swept wing ice shape and aero-performance database for code verification and performance studies
  • Examine approaches for 3-D code inter-comparison studies to help identify paths to improve tools
  • Provide a forum for establishing a working group to continue developing the principles of this workshop
