An airfoil box and associated method are provided. The airfoil box (10) includes two or more half-shell structures (30, 50). Each half-shell structure (30, 50) is an integral or unitary member that includes at least a portion of the outer skin (16) of the airfoil as well as stiffener members (34, 54) and connection members (38, 58). For example, the half-shell structures (30, 50) can be integrally formed of composite materials. The half-shell structures (30, 50) can be assembled by connecting the connection members (38, 58) with fasteners (70) such as rivets to form the airfoil box (10). |
