A two wind turbine is operated at a tip speed ration of 9 at a wind speed of 8.94 m/s one of the blade sections has an angle of attack of 7.19 degrees. This particular section is 1.22 m long, has a cord length of 0.811 m and has a center radius of 5.4 m. the operating condition are such that the flow angle is 8.44 degrees and the axial interference factor is o.390 the lift and drag coefficients for this angle of attack are Clift 1.186 and Carag 0.019. the density of air is 1.23 kg/m, Calculate the wind velocity at the hub a) Calculate the relative wind velocity b) Calculate the Lift and Drag forces c) Calculate the THRUST and turn forces d) Calculate the fractional contribution of the lifting and drag forces to the thrust and turn forces
