    Blade loss The article gives results of modeling of dynamics characteristics of the turbofan engine during and after a fan blade loss. To solve the task, the nonlinear non-stationary model was created. It includes the LP rotor, the HP rotor, the cases, the nacelle with the thrust reverser, the engine mount to the pylon, the pylon, the aircraft hanger to the wing. The rotor system model also embraces the rolling bearings, whose stiffness was calculated for the engine work at different regimes, the nonlinear hydrodynamic dampers and the elastic elements (“squirrel cages”).
