A two-bladed wind turbine is designed using one of the LS-1 family of airfoils. The 13 m long blades for the turbine have the specifications listed previously in Table B.4. Assume that the airfoil's aerodynamic characteristics can be approximated as follows (note, x is in degrees): For x < 21 degrees: C) = 0.42625+0.11628 -0.00063973²-8.712 x 10-5-4.2576x10- For > 21: C₁= 0.95 C₁ = 0.011954+0.00019972x+0.00010332 ² For the midpoint of the outermost section of the blade (r/R=0.95) find the following for operation at a tip speed ratio of 8: (a) angle of attack, z, with and without tip losses (b) angle of relative wind, (c) C) and Ca (d) the local contributions to Cp (e) the tip loss factor, F, and the axial induction factor, a, with and without tip losses. How do tip losses affect aerodynamic operation and the local contribution to Cp at this outermost section? A two-bladed wind turbine is designed using one of the LS-1 family of airfoils.
