The majority of the airfoils in use on horizontal-axis wind turbines today were originally developed for aircraft but it has been begun to design airfoil especially for wind turbine for 20 years. Thus the blade needs to be turned further at the tips than at the root, in other words it must be built with a twist along its length. [24] studied the effects of injection angles at 30°, 45° and 60° on leading-edge film cooling for rotating twisted turbine blades at an inlet velocity and temperature of 13 m/s and 315 K, respectively, and found that an injection angle of 30° at the leading edge showerhead holes obtained the optimal film cooling effectiveness. The opposite ends of each sail ( 8 ) are longitudinally twisted to have a pitch angle of approximately 90 degrees. This leads to turbine efficiency decrease and limited capacity. One of the common failure modes of the diesel-engine turbochargers is the high-cycle fatigue (HCF) of the turbine-wheel blades. Each blade is "twisted" so that its lower attachment point is displaced angularly relative to its upper attachment point.
