Abstract
A method for repairing a compressor blade of a turbine engine, the blade including a cat's tongue at the radial end thereof, the radial extension of which is less than a predefined nominal radial extension. The method includes elongating the cat's tongue via a cold-compacting operation applied to the walls of said tongue, such that the radial elongation thereof becomes greater than the nominal extension. The compacting operation is a rollerburnishing operation carried out by moving the end of the blade between two rollers having rectilinear generatrices and spaced apart by a distance smaller than the thickness of the cat's tongue, along the chord connecting the leading edge with the trailing edge thereof.
