摘　　要：基于叶素动量理论分析了小型风力机的气动性能分析模型,并提出了叶片的气动优化设计方法。结合叶片制造和应用中的实际要求,设计了10 kW小型变桨距风力机叶片的气动外形。计算结果表明,设计叶片具有良好的气动性能,验证了该设计方法有效实用。Based on the blade element-momentum theory, this paper studied the aerodynamic performance prediction model for small wind turbines. Accordingly, the optimal aerodynamic design method for wind turbine blades was presented. Applying the proposed method, considering the requirements of blade manufacture and application, the aerodynamic shape of blades of a 10kW small pitch regulated wind turbine was designed. The aerodynamic performance calculation results of the designed wind turbine indicated that the designed blade has high performance, which verifies the effectiveness and functionalities of the proposed method.
