Fracture Analysis of Generator Fan Blades
Three kinds of blades were found in the turbine casing after the accident: fractured blades, cracked blades and un-cracked blades. The failure was at the turbine side of the generator and according to

Fracture Analysis of Generator Fan Blades
Visual inspections were taken on the generator parts especially on the fan blades and the effect of accident on them was studied. Three kinds of blades were found in the turbine casing after the accident: fractured

Generator rotor blade deformation correction
In addition to the verification of critical deformation, i.e. the tower clearance between blade tip and tower surface in particular, verification must be provided that the resonance frequencies of the rotor blade are not excited

Effects of Blade Deformation on the Performance of
Blade deformation in axial fans The blade sections are normally stacked along the centre of gravity The higher stagger angle at the blade tip results in positive lean
