The fan blade includes a first portion, a second portion, a third portion, a leading edge, and a trailing edge. The second portion is positioned on a first side of the first portion. The third portion is positioned on a second side of the first portion. The leading edge defines a leading edge blade angle and the trailing edge defines a trailing edge blade angle. The leading edge blade angle and the trailing edge blade angle are constant within the first portion and the leading edge blade angle and the trailing edge blade angle vary within the second portion and the third portion.
