Zusammenfassung:Structural composite airfoils include a primary structural element, a secondary structural element defining the trailing edge of the structural composite airfoil, and a leading edge skin panel defining the leading edge of the structural composite airfoil. The primary structural element includes an upper skin panel, a lower skin panel, and a front C-channel spar. A first channel of the front C-channel spar faces the leading edge of the structural composite airfoil, and an upper flange of the front C-channel spar forms an acute angle with an elongated span of the front C-channel spar. The leading edge skin panel is positioned adjacent the leading edge region of the primary structural element, with a first end region of the leading edge skin panel being coupled to the upper flange of the front C-channel spar, and a second end region being coupled to the lower flange of the front C-channel spar.
