How a Wind Turbine Works - Text Version | Department of Energy
A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.

Large size bearing test centre for wind | SKF | SKF
Large bearings are difficult to test because it is almost impossible to mimic actual running conditions at such a scale. For this reason, large bearings, such as those used in wind turbines, are usually assessed using only simulation software. While modelling plays an important role, it cannot provide the insight of ‘real’ testing.
Wind Energy Bearings - AEC
These conditions can limit turbine performance and reliability, especially due to bearing-related issues. As the requirement for power generation continuously increases, the turbines grow increasingly large and move to remote loions. This, coined with the operating conditions, makes it very costly to maintain or repair the wind turbines.
