Highlight

The ICE GENESIS project will create the next generation of 3D simulation means for icing. It will allow weather hazards to be more precisely evaluated and properly mitigated thanks to adapted design or optimised protection through either active or passive means.
ICE GENESIS will also 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. The project counts on the international participation of Canada and Japan. The aviation authorities FAA and EASA are members of the Advisory Board.

Launched in January 2019, ICE GENESIS has a total budget of 21 million euros of which 11,9 million funding from European Union’s Horizon 2020 research and innovation programme under grant agreement N° 824310.

The project duration is 60 months.

 

Abstract

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.

The ICE GENESIS consortium brings together 30 partners from 9 countries (France, Austria, Italy, UK, Germany, Belgium, Switzerland, Canada and Japan).

 

Objectives

The top-level objective of the ICE GENESIS project is to provide the European aeronautical industry with a validated new generation of

3D icing engineering tools
(numerical simulation and test capabilities)

addressing App C, App O and Snow conditions, for safe, efficient and cost-effective design and certification of future aircraft and rotorcraft.

 

  • Obj#1: Improve and validate existing 3D numerical tools to predict ice accretion in App C, App O and Snow conditions.

 

  • Obj#2: Upgrade and calibrate icing wind tunnels to allow reproduction of:
    • Supercooled Large Droplets (SLD) in FZDZ (Freezing drizzle) conditions.
    • Snow icing conditions
    • Additionally, to assess the potential of current icing wind tunnels to represent SLD in FZRA (Freezing rain) conditions.

 

  • Obj#3: Build a large-scale experimental database on representative 3D configurations to be used as a solid reference (“ground truth”) for future numerical tools validation.

As a result of the above objectives, the icing community will obtain a set of engineering tools (3D numerical tools and test facilities) to support design and certification of future products.
