A wind turbine generates electricity by using the kinetic energy of wind to spin its blades, which are connected to a rotor. The generator then converts this mechanical energy into electrical energy.

The structure at North Dakota's Garrison Dam houses five turbines – 'Francis' turbines that turn at a rate of 90 revolutions per minute (rpm). The water takes on energy as it flows down the penstock and is carried with force to the turbine.

Blade manufacturing is the process of designing, fabricating, and assembling the blades used in wind turbines. These blades are crucial components of the turbine system as they capture the energy from the wind and convert it into rotational motion to generate electricity.

This leads to windage, where rotating components overheat due to friction with residual air or steam. As temperatures rise, thermal expansion can cause blade-to-casing contact, resulting in severe rubbing, blade liberation, and extensive damage to shaft line components.
