Aero-engines certification process requires well-defined constraints on the maximum allowable stresses for all the components, based on the expected use of the turbomachinery, this is why aeromechanical analysis are needed to predict and avoid vibration issues caused by the interaction between the engine parts and fluid flow. One of the two principal aeroelastic phenomena are forced response, vibrations caused by external forces with a defined amplitude. For the case of bladed disks, of which the stages of the axial compressor and turbine are composed in a modern aeronautical engine, forced response stems primarily from the spatial un-steady pressure field that encounters the blade.
