Abstract:

An experiment of electro-thermal anti-icing on a composite assembly is presented. The experiment is run in a small open-circuit icing research tunnel based on a refrigerant system composed of a freon refrigerator and air turbines, and a spray system consisting of air/fluid nozzles. Temperature distribution is provided for different anti-icing methods by altering air speeds, icing conditions and electro-heating powers. The results show that anti-icing electro-heating power increases with air speed, and air temperature and the liquid water content have a coupled effect on the power needed. Temperature and its gradients in the assembly is in proportion to electro-heating power. Multi-zone heating methods lead to reasonable temperature distribution of the assembly under the same anti-icing thermal loads.
