NON-SYMMETRIC FAN BLADE TIP CLADDING

Abstract:

Fan blade includes airfoil with leading and trailing edges, pressure and suction sides extending outwardly from airfoil base to airfoil tip, and tip cladding with non-symmetric pressure and suction side cladding flanks bonded to airfoil tip along pressure and suction sides respectively. Pressure and suction side cladding flanks may include non-symmetric or different pressure and suction side cladding radial heights and/or different pressure and suction side cladding radial locations of pressure and suction side cladding flank portions of pressure and suction side cladding flanks in tip cladding portion of tip cladding. One cladding radial heights may be variable in tip cladding portion. Chordwise extending seam may be in pressure side cladding flank portion and/or chordwise extending slot may be in suction side cladding flank portion. Cladding flanks may be stronger, more ductile, or less brittle than composite material of composite core of airfoil.
