A three-bladed rotor of a HAWT with blades of 20 m tip radius is to be designed to work with a constant lift coefficient CL = 1:1 along the length of the span at a tip- speed ratio, J = 5.5. Using Glauert's momentum analysis of the "ideal wind turbine," determine the variation of the chord size along the length of the span for the radius range of 2.8 m to a radius of 19.5 m. Note: It is expected that students attempting this classical problem will need to become familiar with the theory of Glauert outlined in section "rotor optimum design criteria." Also, this problem requires the application of the BEM iterative method of solution. Students are recommended to write a computer program for solving this type of problem, probably saving much time.
