A shell of a stator for a module of an aircraft turbo-engine including a plurality of through openings each configured to house a stator blade, each opening forming a skeleton extending between a first end configured to house the trailing edge of the blade and a second end configured to house the leading edge of the blade. At least one of the openings is associated with a mechanical load transfer slit passing through the shell, and arranged facing and at a distance from the first end of the opening along the direction of the skeleton.

Shell for aircraft turbo-engine stator with mechanical blade load transfer slits

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.
