Short summary

In the paper, rotor stability in slow idling operation is assessed on the basis of nonlinear time domain and linear eigenvalue analyses. A consistent and computationally cost effective modeling environment has been presented for the analysis of parked or idling rotors. The analysis shows that the lowest damped modes of a 10 MW idling rotor are out-of-plane modes (symmetric and asymmetric).
