Abstract
An airfoil assembly includes an airfoil body extending between a leading edge, a trailing edge, a suction side, and a pressure side. A first sheath having an outer side and an inner side forms a cavity for receiving at least a portion of the airfoil body and is bonded on the inner side to the leading edge of the airfoil body. The first sheath is formed of a titanium-based metallic material. A second sheath is bonded to the outer side of the first sheath.
Claims20
An airfoil assembly comprising:
- an airfoil body extending between a leading edge, a trailing edge, a suction side, and a pressure side;
- a first sheath having an outer side and an inner side that forms a cavity for receiving at least a portion of the airfoil body, the inner side being bonded to the leading edge of the airfoil body, and the sheath being formed from a titanium-based metallic material;
- and
- a second sheath bonded to the outer side of the first sheath.
