摘　　要：通过将NREL Phase VI 5.029 m叶片的翼型积叠线向尾缘方向弯曲造型完成后掠改型,对原型直叶片与改型后掠叶片进行三维CFD数值求解获得其气动参数,对比文献数据提出后掠改型有利于延迟失速的论断,并通过对原型直叶片与改型后掠叶片的边界层流动及其影响因素分析给予确认。To form a aft-swept blade of wind turbine, stacking line of the prototype NREL Phase VI 5.029-meter blade was curved outboard. CFD simulation on the prototype straight blade and modified aft-swept blade was carried out, comparing with results from the literature, a point was put forward that aft-swept formation would benefit the stall delay. After analyzing boundary layer flow field and the influence factors, the point was supported and verified.
