An airfoil blade assembly includes an upper airfoil shell, and a lower airfoil shell and a pair of upper legs protruding from the upper airfoil shell and extending towards the lower airfoil shell. A pair of lower legs protrudes from the lower airfoil shell and extending towards the upper airfoil shell and are formed by bending material of the lower airfoil shell back upon itself. An upper strengthening rib formed is in the upper airfoil shell, and a lower strengthening rib is formed in the lower airfoil shell. The pair of upper legs and the pair of lower legs are abutting when the upper airfoil shell and the lower airfoil shell are selectively fixed to one another.

Airfoil blade and method of assembly

An airfoil blade assembly includes a first shell member having a body having a first lock seam formed at one end thereof and a free distal end opposite the first lock seam, and a second shell member having a body having and a second lock seam formed at one end thereof and an a free distal end opposite the second lock seam. The second shell member is inverted with respect to the first shell member. The free distal end of the first shell member is captured within the second lock seam of the second shell member and the free distal end of the second shell member is captured within the first lock seam of the first shell member to lock the blades to one another.
