Abstract
The probability of fan blade destruction is extremely small but not equal to zero. The consequences of fan blade-out (FBO) can be catastrophic. The absence of dangerous consequences during FBO event should be confirmed by expensive tests. This causes urgency of developing accurate computational techniques for engine structural frame vibrations analysis. In this paper, we propose an approach to determining rotor-casing system dynamic response to unbalance associated with FBO. The problem is solved in a nonlinear non-stationary formulation. Rotor-casing contact interaction, blades crown stiffness and changes in rotational speed are taken into account.
