... the subsequent damages at the high speed of rotation. In rotor A, the maximum secondary damage is seen in the second and fifth stages, which are adjacent to the third and fourth stages in which the blades are completely sheared. In this rotor, it is reasonable to suspect that a dovetail mounting...
