Structural composite airfoils include a front C-channel spar having an upper flange coupled to an upper skin panel, and a lower flange coupled to a lower skin panel. The upper skin panel includes a joggle adjacent an upper leading edge end, with the joggle being positioned forward of the front C-channel spar. A lower skin surface of the upper leading edge end faces an internal volume defined between the upper skin panel and the lower skin panel. An upper skin surface of the upper leading edge end faces an internal surface of the lower leading edge end of the lower skin panel, and the upper leading edge end of the upper skin panel is coupled to the lower leading edge end of the lower skin panel forward of the front C-channel spar. The leading edge has a bullnose shape defined by the lower skin panel.
