In the first part of the program the optimum rotor configuration for twist and chord is determined using the momentum and blade element theories for a rotor without coning or tilting and assuming zero drag average wind velocity. Then coning angle and mass distribution are determined from an iterative procedure considering the effect of drag. The equations have further been extended to include the influence of tilting angles and several wind conditions, such as wind gradient, tower shadow and wind shifts. Numerical results obtained with the present method agree well experimental and other numerical data. %U https://www.ije.ir/article_71084_d03e6028c636f4d846c7cc43e05de470.pdf
