Abstract

A method for developing a mistuning model to facilitate dispositions of potential repair blend profiles on damaged blades of a bladed rotor can include collecting a vibration data, the vibration data comprising blade-alone frequency for each of a plurality of blades in the bladed rotor on a gas-turbine engine; compiling the vibration data with vibration data sets across a fleet of gas-turbine engines to generate a vibration fleet data; calculating a system vibration amplitude as a function of frequency shift for each of a plurality of system modes based on the vibration fleet data to generate a frequency shift impact on the system vibration amplitude; and developing, based on the frequency shift impact, the mistuning model, the mistuning model configured to receive a blade-alone frequency parameter as an input perturbation. The developed mistuning model can be used for potential repair blend dispositions.
