Structural composite airfoils include a primary structural element, and a secondary structural element defining a trailing edge of the structural composite airfoil. The primary structural element extends from a leading edge region to a trailing edge region, with the leading edge region of the primary structural element forming a leading edge of the structural composite airfoil. The primary structural element includes an upper skin panel, a lower skin panel, and a spar. The spar includes a plurality of upper flanges coupled to the upper skin panel and a plurality of lower flanges coupled to the lower skin panel. The spar extends spanwise across the structural composite airfoil. The spar also extends along a chord length of the structural composite airfoil. The spar may be a unitary, monolithic body, with an elongated span extending between each adjacent upper flange and lower flange.
