The failed fan consisting of 11 blades was mounted on the generator-rotor at the turbine end, and had a total service life of about 41000 hours prior to the failure. The fan rotational speed
you can order up a diagnostic manual for your unit that has nice pics and description how to do it. after new fan is installed the rotor bolt needs to be tightened to 30 Ft Lbs.
The potential failure of generator rotor fan vanes and blower blades has been identified as an area for detailed risk assessment in the electric power generation industry.
The mechanical analysis capable of predicating stress and dynamic characteristics of turbo generator fan blades is needed to decrease blade failures. The experimental method and FEM
Fracture surfaces of two sets of rotor blades failed after strong testing procedures of aircraft engines in the test-stand are investigated by means of SEM. While the process of fatigue fracture in

short circuit between rotor and stator and consequently generator explosion and lots of financial loss. Cooling system equipments were supplied by GEC-ALSTHOM Belford under the following
The potential failure of generator rotor fan vanes and blower blades
In order to study the imposed stresses of the fan blades due to operation, fan should be simulated. To do this, Computational Fluid Dynamic (CFD) code and Finite Element Method (FEM) were deployed
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
Gas turbine blade failures can occur due to various reasons such as fan blade off, bird strike, icing, and containment issues. Understanding these failure scenarios is crucial for ensuring
