The purpose of most wind turbines is to extract as much energy from the wind as possible, and each component of the turbine has to be optimised for that goal. Optimal blade design is influenced by the mode of operation of the turbine, that is, fixed rotational speed or variable rotational speed and, ideally, the wind distribution at the intended site. In practice engineering compromises are made, but it is still necessary to know what would be the best design.

Optimising a blade design means maximising the power output, and so a suitable solution to BEM Eqs. (3.54 or (3.59) and (3.55)) is necessary.
