A leading edge structure for an aerodynamic surface includes a support structure made of fiber-reinforced synthetic material and a skin structure made of metal mounted on the support structure. The support structure includes an inner laminate, an outer laminate, and longitudinally extending tubes and channels arranged between the inner and outer laminates, as well as a synthetic foam filler material in the spaces between the tubes, channels, and laminates. The skin structure includes an outer skin having perforations, especially in the form of suction holes, an inner skin, and spacer members interconnected therebetween so as to form a substantially form-stable metal skin structure. Respective holes pass through the inner skin, the outer laminate, and the walls of the tubes and channels in order to communicate the suction hole perforations of the outer skin with the interior spaces within the tubes and channels. The skin structure is adhesively bonded to the support structure. In a method for making the leading edge structure, the prefabricated components of the support structure are laid up, molded and cured in a positive mold, the prefabricated components of the skin structure are formed and soldered together on a positive mold, and then the skin structure is adhesively bonded onto the support structure.

[ What is claimed is:] [1.] A leading edge structure for an aerodynamic surface, comprising a support structure, a skin structure arranged on said support structure, and an adhesive that bonds said skin structure onto said support structure, wherein:said support structure comprises an inner laminate, an outer laminate spaced from said inner laminate, and channel members interposed between said outer and inner laminates, and said support structure essentially consists of at least one fiber-reinforced synthetic composite material;said skin structure comprises an inner skin surfacially bonded to said outer laminate by said adhesive interposed therebetween, a perforated outer skin that has first holes therein and that is spaced from said inner skin, and spacer members interposed between said outer and inner skins, and said skin structure essentially consists of at least one metal; andsaid first holes in said outer skin pass through said outer skin and into respective hollow spaces formed between said outer and inner skins, and said outer laminate and said inner skin mutually have a plurality of second holes therethrough that communicate said hollow spaces with hollow channels formed within said channel members.
