ABSTRACT:
A deicer pad for use on an aircraft wing wherein the deicer pad is constructed to have an intermediate portion and two spaced apart portions. The pad is a composite member of at least two plies of materials stitched along the intermediate portion to provide two spanwise passageways, and stitched in a zig-zag pattern along the spaced apart portions to form chordwise passageways. Alternate chordwise passageways communicate directly with the spanwise passageways while the remaining chordwise passageways communicate with the adjacent spanwise passageways around the stitching. The remaining chordwise passageways also communicate with the adjacent alternate chordwise passageways around the stitching which stitching forms the separation between alternate chordwise passageways.
