An inverse method for the aerodynamic design of horizontal axis wind turbines has been developed, and a computer program (PROPID) has been written based on the approach. To illustrate the inverse design method, a new 10.5 m blade for use on the stall-regulated three-bladed Micon 108 and Bonus 120 wind turbine generators has been designed to replace the aging AeroStar 9.06 m blade currently in widespread use on thousands of machines. The design effort is focused improving the blade performance for the Micon 108 machines since they are more numerous that the Bonus 120's. As compared with the AeroStar 9.06 blade, the improvement in annual energy of the new blade is 13-25% over the average wind speed range 4.47-8.94 m/s for the Micon 108. When dirty, the new blade produces 28-53% more annual energy than the AeroStar blade.
