Hatch, C., Gent, R., and Moser, R., "Initial Results from a Hybrid Electro-Thermal Electro-Mechanical Simulation Tool (HETEMS)," SAE Technical Paper 2015-01-2142, 2015, doi:10.4271/2015-01-2142.
Low power ice protection systems are an important research area that is highlighted in the EU Clean Sky programme.In this paper an icing wind tunnel test of a full-scale wing incorporating both an electro-thermal and a hybrid electro-thermal electro-mechanical system is described. A description of a software tool to analyse both systems as full 3D models is also given. Preliminary comparisons of test data and prediction are shown both for the electro-thermal system and the hybrid system.Initial comparisons show a reasonable correlation in the main with recommendations for a structure tear-down to identify exact internal transducer locations. Recommendations are also made with regard to undertaking tests to determine a more consistent set of mechanical failure properties of ice. Future work in the development of the tool is also discussed.
