Where are bolts used in a wind turbine?

Wind turbines, like helicopters, are fatigue machines—always vibrating and working to loosen their fasteners. More vibration will come as engineers develop longer blades to capture more wind energy and towers reach higher to accommodate them. These increased vibration levels may loosen some tower fasteners. To prevent this, engineers are looking for better ways to measure…

Propeller (aeronautics) - Wikipedia

In aeronautics, a propeller, also called an airscrew, converts rotary motion from an engine or other power source into a swirling slipstream which pushes the propeller forwards or backwards. It comprises a rotating power-driven hub, to which are attached several radial airfoil-section blades such that the whole assembly rotates about a longitudinal axis.
