Podgorny Institute of Mechanical Engineering Problems of the National Academy of Sciences of Ukraine popup.description2  The formulation of the problem and a comparative analysis of the existing mathematical models of damage to the rotor blades of the fan at the impact of a bird are carried out. A mathematical model of a drummer bird has been built. The model was verified based on the results obtained when a bird collided with a rigid slab. Conducted research of elastic and elastoplastic deformation of an individual blade under the action of forces equivalent to impact. A model of a full impeller is constructed for adequate modeling of the elastic-plastic dynamic response of the blades due to the action of the shock load.
