A set of optimal numerical model for the aerodynamic design of windmill rotor wasdiscussed in this paper. All the parameters about rotor sizes, rotor structures, and workingconditions of wind turbine were optimized through the shaft power calculations of windrotor. This set of numerical model realizes that all the parameters of wind rotor are fullyoptimized through rotor designing procedure. With the numerical model, it is possible to getthe optimal wind rotor. The aerodynamic design for the wind rotor becomes more simpleand reliable.
