Title: METHODS AND SYSTEMS FOR SELF-LUBRICATING ICEPHOBIC ELASTOMER COATINGS
Abstract:
Methods and systems for providing self-lubricating icephobic elastomer coatings (SLICs) can include forming the coatings from a three-component composition of a silicon elastomer, silicone oil, and a solvent, such as xylene. The coatings can provide ultra-low ice adhesion and high durability levels for a variety of applications operating in harsh icing environments, such as in aviation. In an example, the coatings or SLICs can be used in combination with a localized heating component to provide a Coating Heating Ice Protection (CHIP) system to minimize ice adhesion on the surface of an aircraft component, such as an airfoil or fan blades. Methods and systems for evaluating the ice release performance of the coatings can include high speed impaction of supercooled droplets on rotating fan blades to evaluate the coatings under conditions more representative of in-flight ice conditions, as compared to traditional testing methods.
