The present work presents the aeroelastic analyses of mistuned blisk forced response employing a surrogate lumped mass model with aerodynamic influence coefficients. Prior to these, the state of the art in mistuning analysis is summarised and the theoretical background of the structural as well as the aerodynamical model employed in this work is illustrated. Consequently, the validation of the aeroelastic methods is presented at the example of the compressor like Standard Configuration 10, a standardised test case of an aerofoil vibrating in a cascade, and the aerodynamical model is validated against bidirectionally coupled fluid structure interaction simulations of a 2D compressor rotor model. Finally, the aeroelastic behaviour of a mistuned blisk is analysed featuring measured mistuning patterns and extensive probabilistic analyses of mistuned blisk forced response.
