摘　　要：文章归纳了不同叶片气动设计理论中的诱导速度处理形式,评价了诱导速度的求解过程与应用前景。结果显示,现有叶片设计方法中的诱导速度处理方式单一,采用基于粘性流的计算流体力学(CFD)理论与自由涡理论是提升风力机叶片优化设计的主要策略。The treatment manners of induced velocity on vane are concluded in different design theo- ries, and solution process and application foreground of induced velocity are also appraised. The investigation results show that the existing treatment manner of induced velocity is rather too simple in every vane design methods. The main strategy of improvement of aerodynamics optimization design should include computa-tional fluid dynamics theory based on viscidity and free eddy theory.
