METHOD FOR REPAIRING A BLADE

摘要

A method for repairing a blade in a gas turbine engine comprises the steps of: isolating the damage on the airfoil of the blade; forming a cut back in the shape of elongated "D" shaped recess with a pair of fillets, a depth and a longitudinal axis of the "D" shaped recess having a length along the leading or trailing edge of the airfoil; and the fillets having a respective radius.
