Patent ID: 7374404

Claim:
A method for assembling a turbine engine to facilitate preventing ice accumulation on the turbine engine during engine operation, the gas turbine engine including a fan assembly, said method comprising: coupling a plurality of fan blades to a fan rotor, wherein each of the plurality of fan blades has a length that extends from an airfoil root radially outwardly to an airfoil tip; and applying a polyurethane material to at least a portion of at least one of the fan blades to facilitate preventing ice accumulation on the at least one fan blade, the polyurethane material having a length selected based on the centrifugal force experienced by the ice accumulated on the at least one fan blade during icing conditions, wherein the polyurethane material is applied to that portion of at least one of the fan blades that extends from a distance aft of a leading edge of the blade towards a trailing edge of the blade.
