摘要
研究NPU-WA风力机专用翼型族4个厚翼型(相对厚度25%、30%、35%和40%)的粗糙敏感度,并与相同厚度的经典风力机翼型进行比较。结果表明NPU-WA厚翼型满足气动设计要求,前缘粗糙度对NPU-WA翼型的影响和DU系列相同厚度翼型的影响非常类似,但翼型总体性能要优于后者。
Due to the very strong reduction of roughness sensitivity, the design of inboard airfoils can be focus on high lift and structural demands. The roughness sensitivities of 4 thick NPU-WA airfoils (relative thickness t/c = 0. 25, 0. 30, 0. 35 and 0. 40) for wind turbine application were studied, and compared with classic airfoils with the same thickness. The results show that NPU-WA thick airfoils meet the aerodynamic requirements, and the roughness sensitivities of NPU-WA airfoils are very similar to DU-airfoils, but the overall performances are better than later.
