Abstract
An aircraft propeller de-icing system comprises at least one propeller blade coupled to a rotatable prop assembly. The prop assembly is configured to rotate in response to rotatably driving a propeller shaft. At least one resistive-inductive heating unit is coupled to the at least one propeller blade. The resistive-inductive heating unit is configured to generate eddy currents that induce inductive heat in response to an electric current. A contactless power transfer system generates the electrical current in response to transferring power across an air gap separating the propeller shaft from the contactless power transfer system.
