Abstract: A method of repairing an integrally bladed rotor (IBR) may comprise: performing a vibratory analysis of a rotor module including a first inspected IBR with a potential repair shape for the IBR; determining an undesirable vibratory characteristic of a second inspected IBR in the rotor module; iterating the potential repair shape for the first IBR to eliminate the undesirable vibratory characteristic of the second inspected IBR; and repairing the first IBR with a selected repair shape based on determining the potential repair shape eliminates the undesirable vibratory characteristic.

Abstract: A method is providing comprising receiving, via a processor, a digital representation of a potentially repaired blade from an inspection system, the digital representation including a repair blend profile, the digital representation based on an inspected blade of an inspected bladed rotor; generating, via the processor, an airfoil definition file corresponding to the digital representation, inputting, via the processor, the airfoil definition file into an aerodynamic simulator, receiving, via the processor, simulation results from the aerodynamic simulator of the potentially repaired blade; analyzing, via the processor, an overall engine impact of the potentially repaired blade based on the simulation results, inputting, via the processor, a plurality of simulation results into an aerodynamic effect translator, and receiving, via the processor, a translated impact for local effect of a repaired bladed rotor with the potentially repaired blade.
