ICE GENESIS Creating the next generation of 3D simulation means for icing

Summary

Current design methodologies used to characterise ice accretion and its effects on air vehicle components and power plant systems are mainly based on empirical methods, comparative analysis, 2D simulation tools and past experience gained on in-service products. Due to the associated uncertainties, cautious design margins are used, leading to conservative and non-optimised solutions.
As future air vehicle and propulsive system architectures introduce radical design changes, it will no longer be possible to rely on the existing design methodologies, making future development extremely difficult to accomplish efficiently and within short development cycles that are demanded by customers and desired by industry. These difficulties are increased by the recent changes in certification regulations, in particular for Supercooled Large Droplets (SLD), which require manufacturers to certify their products against more stringent requirements. Snow also remains a challenge, especially for turbine engines and APUs. ICE GENESIS will provide the European aeronautical industry with a validated new generation of 3D icing engineering tools (numerical simulation tools and upgraded test capabilities), addressing App C, O and snow conditions, for safe, efficient, right first time, and cost effective design and certification of future regional, business and large aircraft, rotorcraft and engines. ICE GENESIS will permit weather hazards to be more precisely evaluated and properly mitigated thanks to adapted design or optimised protection through either active or passive means. Furthermore, ICE GENESIS will pave the way for 3D digital tools to be used in the future as acceptable means of compliance by the regulation authorities. Overall, ICE GENESIS will contribute to flight safety, reduced certification costs and increased operability.

Original description

Current design methodologies used to characterise ice accretion and its effects on air vehicle
components and power plant systems are mainly based on empirical methods, comparative analysis,
2D simulation tools and past experience gained on in-service products. Due to the associated
uncertainties, cautious design margins are used, leading to conservative and non-optimised solutions.
As future air vehicle and propulsive system architectures introduce radical design changes, it will
no longer be possible to rely on the existing design methodologies, making future development
extremely difficult to accomplish efficiently and within short development cycles that are demanded
by customers and desired by industry. These difficulties are increased by the recent changes
in certification regulations, in particular for Supercooled Large Droplets (SLD), which require
manufacturers to certify their products against more stringent requirements. Snow also remains
a challenge, especially for turbine engines and APUs. ICE GENESIS will provide the European
aeronautical industry with a validated new generation of 3D icing engineering tools (numerical
simulation tools and upgraded test capabilities), addressing App C, O and snow conditions, for safe,
efficient, right first time, and cost effective design and certification of future regional, business and
large aircraft, rotorcraft and engines. ICE GENESIS will permit weather hazards to be more precisely
evaluated and properly mitigated thanks to adapted design or optimised protection through either
active or passive means. Furthermore, ICE GENESIS will pave the way for 3D digital tools to be used
in the future as acceptable means of compliance by the regulation authorities. Overall, ICE GENESIS
will contribute to flight safety, reduced certification costs and increased operability.
