摘要
利用经验公式、小攻角下翼型气动特性数据建立了翼型在-180°～180°攻角范围内的气动特性估算模型。以NACA0012翼型、NACA0015翼型为例,对翼型全流向范围的升力系数、阻力系数、力矩系数进行了估算,并对风力机翼型DU96-W-180的升力系数、阻力系数进行了估算,将估算结果与实验结果进行比较,验证了估算方法的合理性。
A estimation model was built to predict the aerodynamic characteristics of airfoils through ± 180° angle of attack. The lift coefficients, drag coefficients, moment coefficients of full range section were estimated for NACA0012 airfoil, NACA0015 airfoil and DU96-W-180 airfoil. Comparisons between the model predictions and experiment data showed that the estimation model is reasonable.
