摘要
以最大升力系数下降率为评价指标,针对自主研发的风力机叶片外侧专用翼型CAS-W1-150/180/210进行粗糙敏感性核算和试验分析,并通过调整CAS-W1-210翼型前缘半径、尾缘厚度和上表面厚度以及采用S型后加载下表面尾形的方法,改善了翼型表面的压力分布,有效降低了此翼型的粗糙敏感性,优化得到了粗糙敏感性更低、气动性能更优的新翼型CAS-W2-210。
The roughness sensitivity of dedicated wind turbine airfoils CAS-W1-150/180/210 evaluated with the decrease rate of maximum lift coefficient were checked and analyzed by calculation and experiment. A new CAS-W2-210 which had lower roughness sensitivity and better aerodynamic performance than the original CAS-W1-210 was obtained through changing the leading edge radius, trailing edge thickness and upper surface thickness, as well as using aft-loading lower surface tail with S shape.
