Darrieus windmill blade design end attachment detail.

Detail of airfoil blade end attachment intended for a Darrieus Windmill design.  Fasteners are also aluminum, to prevent long term issues with corrosion.  Flats were machined on both sides of the blade to create a stable mounting surface.

Standard Windmill Blade build using airfoil extrusion.

Standard windmill blade built using NACA aluminum airfoil shape.

Homebrew version of a standard windmill blade fabricated using the extruded airfoil shape and simple steel strapping. Corrosion is minimized by sandwiching a thin layer of neoprene between the steel and aluminum.  This particular blade design was attached directly to an automotive alternator's shaft.
