Method for reshaping a turbomachine blade that has at least one zone that has become deformed using peening

A method to reshape a turbine engine blade which includes at least one deformed zone, the method comprising:

• acquiring a profile of the blade;
• comparing the profile with a reference profile so as to deduce therefrom at least one deformed zone of the blade;
• dividing the deformed zone into a plurality of non-overlappingly divided deformed zones:
• comparing the divided deformed zone with a deformation database including a plurality of divided deformed zones associated respectively with a plurality of parameterizations of a peening device;
• determining the parameterization associated with the divided deformed zones;
• peening by ultrasonic peening each of the divided deformed zones of the blade individually so as to not significantly raise a temperature of the blade using the peening device as a function of the determined parameterization so as to restore a shape of the deformed zone,
• wherein the blade includes two faces opposite one another, and when one of the divided deformed zones is situated on one of the two faces, a surface situated on the other of the two faces opposite the one of the divided deformed zones is free to deform during the peening of the one of the divided deformed zones.
