Question:
A two-bladed wind turbine is operated with the following characteristics: Upstream velocity: 7.3 m/s, Axial induction factor: 0.33, Blade flow angle: 9.1 degrees, Angle of attack: 7.9 degrees, Width of blade section (dr): 2.7 m, Chord: 1.15 m, Radius of blade section: 8.2 m and assume the density of air is 1.225 kg/m^3. Use the following equations to approximate values for CL and CD as a function of the angle of attack for this assessment.
CL=0.426+0.1160.0006428.7x10534.26x1064
CD=0.012+0.0002+0.00012
Find the Power in Watts generated by the blade segment (round to 2 decimal places).Do NOT multiply by the number of blades.
