An airfoil (10) comprises an airfoil body (12) with an internal cavity (16) and inner and outer covers (32,34). The airfoil body defines a first major surface of the airfoil, and a rib (18) extends along the internal cavity. The inner cover (32) is bonded to the airfoil body (12) over the internal cavity (16), and includes a coupling element (20) extending along the internal cavity in cooperative engagement with the rib. The outer cover (34) is bonded to the airfoil body (12) over the inner cover (32), and defines a second major surface of the airfoil. |
