Rotorblade airfoil design method of wind power generator using genetic algorithm and airfoil designed accordingly

摘要

PURPOSE: A rotor blade airfoil design method for a wind turbine using genetic algorithm and an airfoil by the same are provided to optimize the airfoil profile of a rotor blade, thereby ensuring good blade efficiency. CONSTITUTION: A rotor blade airfoil design method for a wind turbine using genetic algorithm comprises the steps of: creating an airfoil profile using an optimization method(S2), calculating an objective function(S5), applying genetic algorithm(S6), drawing a candidate airfoil profile group optimized through the genetic algorithm(S7), and selecting the optimum profile from the candidate group(S8).
