A coated fan rotor blade and method for coating a fan rotor blade. The coated fan rotor blade includes a fan rotor blade; and a coating disposed on said fan rotor blade. The coating comprises a binder; and a filler made up of a plurality of particles. The filler material is incorporated into the binder material, and the particles in the filler interact to produce vibrational damping. In particular, the coating includes small, dense, flattened particles or plates that are incorporated into a thin layer of visco-elastic material, such as rubber, silicone, fluoro-elastomer, or urethane and bonded to the surface of the rotor blade to provide damping of high frequency excitation.

Vibration damper coating

A method for operating an aircraft engine facilitates preventing ice accumulation on the aircraft engine. The method comprises coupling a semi-permeable membrane to the engine adjacent an outer surface of the engine, coupling a fluid reservoir to the aircraft engine in flow communication with the semi-permeable membrane, and supplying fluid from the fluid reservoir to the semi-permeable membrane to facilitate preventing ice accumulation on the aircraft engine outer surface.
