ABSTRACT:
A deicer pad for use on an airfoil wherein the airfoil has a leading edge and a stagnation line. The deicer pad is constructed to have an intermediate portion or region and two spaced apart portions or regions and with inflatable passageways only located on or within the two spaced apart portions. The pad is mounted on the airfoil so that the intermediate portion which is non-extensible or non-stretchable overlies the leading edge and the stagnation line of the airfoil. The stagnation line is generally parallel to the leading edge of the airfoil. The passageways in the two spaced apart portions of the deicer are inflatable either simultaneously or in seriatim order and effect the breaking up of the ice over the entire deicer. The inflatable passageways are the sole means for deicing.
