DNS of the several stages of the ice accretion: Figures 1-3: Cooling of the hot substrate and forming of a liquid film due to accretion of droplets and evaporation of such and Figures 4-6: Impact and adhesion of ice particles to that liquid film and freezing of the water layer which leads to a mechanical connection between the ice and the substrate. The figures show the temperature distribution in the substrate, the liquid water (blue surface) and the ice (white surface).
HAIC (High Altitude Ice Crystals) is a large-scale integrated project which aims at enhancing aircraft safety when flying in mixed phase and glaciated icing conditions.
In anticipation of regulation changes according to these particular icing conditions, the HAIC project will provide the necessary Acceptable Means of Compliance (numerical and test capabilities) and appropriate ice particle detection and awareness technologies to the European Aeronautics industry for use on-board commercial aircraft.
Coordinated by AIRBUS, the HAIC Consortium brings together 34 partners from 11 European countries and 5 International partners from Australia, Canada and the United States.
The total budget of the project is 22.8 M€, partially funded by the European Commission under FP7-AAT-2012-3.5.1-1.
Starting from August 2012, the project is expected to be completed by January 2017.
