    Abstract: An airfoil for a turbofan engine includes a first contoured sidewall, a second contoured sidewall, a leading edge, and a trailing edge with each extending in a spanwise direction defined between a root and a tip portion of the airfoil. The first contoured sidewall and the second contoured sidewall define an outer surface of the airfoil. The airfoil further includes a plurality of protrusions where each protrusion of the plurality of protrusions has a curvilinear shape and extends outwardly from the outer surface along at least one of the first contoured sidewall or the second contoured sidewall. The plurality of protrusions is defined downstream from a mid-point of a chord length of the airfoil and terminates upstream of the trailing edge.

    Abstract: A composite airfoil assembly for a turbine engine. The composite airfoil assembly has an airfoil outer surface defining opposing pressure and suction sides, which extend between a leading edge and a trailing edge. The composite airfoil assembly includes a composite airfoil having a woven core and a skin applied to at least a portion of a core exterior. The composite airfoil assembly also includes a cladding coupled to a skin outer surface where at least one edge or portion of the cladding is located adjacent at least one of the trailing edge, a root, or a tip, wherein the cladding includes a tapered portion.
