Rotordynamic analysis of asymmetric turbofan rotor due to fan blade-loss event with contact-impact rub loads

Loss of a blade from a running turbofan rotor introduces not only huge imbalance into the dynamical system rather it makes the entire rotor asymmetric as well. In a nonsymmetric rotor, the various terms of mass, gyroscopic and stiffness matrices also become time-dependent. In this paper, all the dyn...
