Method for restoring airfoil contour on integrally bladed rotors

An integrally bladed rotor includes a central hub and a plurality of airfoils or blades (22). The blades (22) are repaired by rebuilding their surfaces beyond the original shape, such as by adding weld material (26). The contour (32) of the blade is then returned to the desired shape using superabra...

Zusammenfassung:	An integrally bladed rotor includes a central hub and a plurality of airfoils or blades (22). The blades (22) are repaired by rebuilding their surfaces beyond the original shape, such as by adding weld material (26). The contour (32) of the blade is then returned to the desired shape using superabrasive quills (30).
