A three-bladed HAWT of 50 m diameter, has a constant blade chord of 2 m. and operates with a tip- speed ratio, J 5 4.5. Using an iterative method of calculation determine the values of the axial and tangential induction factors (a and a´) at a radius ratio of 0.95 and the value of the lift coefficient. Assume the drag coefficient is negligible (and can be ignored) compared with the lift coefficient and that the pitch angle of the blades β = 3°.

Note: This problem requires the application of the BEM iterative method. Students are recommended to write computer programs for solving problems of this type. (Stop the calculation after three iterations if solving manually.)
