Claim Text:
1. A horizontal axis wind generator hub assembly, comprising: a. a hub assembly that rotates around a horizontal axis with at least three spatially aligned blade mounting surfaces; and, b. a lightweight hybrid airfoil/sail blade attached to each said mounting surface, each said blade including an internal frame with a leading edge support member and a trailing edge support member, each said leading edge support member and said trailing edge support member includes a proximal end and a distal end, attached to said proximal ends of said leading edge support member and said trailing edge support member is a hub mounting plate that attaches to said mounting surface on said hub assembly, attached to said distal ends of said leading edge support member and said trailing edge support member is an end plate, attached to said leading edge support member and extending over said trailing edge support member and extending on one side of said blade is an outer skin layer, said outer skin layer has an inside surface and an airfoil profile forming a leading edge and trailing edge on said blade, said blades being oriented on said hub assembly so that when said hub assembly is turned into the wind, the wind flow against said inside surface of outer skin layer and partially directed by said end plate over said trailing edge.
