Abstract
An airfoil deicing system includes an airfoil substructure having an apex corresponding to the portion of the airfoil where the radius of curvature of the airfoil is smallest, the airfoil and the apex being bisected by a centerline, a deflectable shell disposed over the airfoil substructure for meeting and breaking an impinging airstream, a deflection means disposed between the airfoil substructure and the deflectable shell at the apex for deflecting the deflectable shell in the area of the apex away from the airfoil substructure and, at least one compressible zones provided beneath the deflectable shell adjacent the apex on either side of the centerline, the compressible zones facilitating deflection of the deflectable shell overlying the compressible zones toward the airfoil substructure when the deflection means deflects the deflectable shell.
