Abstract
A disclosed example self-contained counter rotating turbo prop system includes a power generating system that produces electric power for a de-icing system. A bearing/generator assembly includes a plurality of permanent magnets and coil assemblies separated by an air gap. Relative rotation between first and second parts of the bearing/generator assembly provides for the generation of electric power utilized to drive the heating elements mounted to the propeller blades.
