ABSTRACT:
A deicer comprises a skin heating device immediately subjacent an outer skin overlying an apex of a leading edge, and a skin deflection device immediately subjacent the outer skin chordwise aft of the apex. The skin heating device prevents the formation of ice over the apex and the skin deflection device 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.
