A deicer comprises a skin heating means immediately subjacent an outer skin overlying an apex of a leading edge, and a skin deflection means immediately subjacent the outer skin chordwise aft of the apex. The skin heating means prevents the formation of ice over the apex and the skin deflection means deflects the outer skin to expulse ice formed chordwise aft of the apex. A controller controls the heating and deflection cycles to minimize power consumption of the deicer.

[ We claim:] [1.]1. A deicer for deicing an outer skin associated with a substructure, the substructure having an apex underlying the area of the outer skin where the radius of curvature is smallest, the deicer comprising:a heater suitable for disposal beneath the outer skin at a first area near the apex of the substructure for heating the outer skin when energized to thereby melt ice accumulated over the first area;at least one skin deflector suitable for disposal beneath the outer skin at a second area for deflecting the outer skin away from the substructure when energized; anda controller configured to energize the heater and the at least one skin deflector, wherein the controller is configured to adjust a control parameter for energizing at least one of the heater and the at least one skin deflector as a function of an outside operating temperature in which the deicer is operating.
