Titanium sheath and airfoil assembly

摘要

An airfoil assembly (20) includes an airfoil body (22) extending between a leading edge (24), a trailing edge (26), a suction side (28), and a pressure side (30). A first sheath (34) having an outer side (36) and an inner side (38) forms a cavity (40) for receiving at least a portion of the airfoil body (20) and is bonded on the inner side (38) to the leading edge (24) of the airfoil body (22). The first sheath (34) is formed of a titanium-based metallic material. A second sheath (60) is bonded to the outer side (36) of the first sheath (34).
