Nomenclature

L = lift

D = drag

= angle of attack

= twist t = spar cap thickness c = chord

= tip speed ratio d = rotor diameter Cp = centre of pressure

Table 1: Modern and historical rotor design

The design of the airfoils is critical as this can increase the overall efficiency of wind turbines. Every aero

dynamic surface must undergo an expensive process of testing of its performance in a wind channel. One way to
