This chapter starts by explaining how aerodynamic loads are created from the flow past the rotating blades and why these can be used to extract power from the wind. Next, it is shown how these loads for a given geometry, wind speed, and angular velocity can be quantified using a Blade Element Model or by solving directly the Navier–Stokes equations for the flow past the blades. Also, the unsteady nature of the loads is addressed and a typical design process is sketched.
