摘　　要：为了提高风力机叶片性能,基于家燕翅膀翼型良好的气动特性进行了风力机叶片的仿生设计。采用计算流体动力学,对仿家燕翼型和标准叶片翼型的性能进行模拟和对比,结果表明,仿家燕翼型具有较高升力系数和升阻比。基于家燕翼型进行100 W风力机叶片的仿生设计,并对标准100 W风力机叶片和仿生设计叶片进行数值模拟和风力机效率实验。结果表明:相比于标准叶片,仿家燕风力机叶片展向位置翼型上下表面压力差有较大提高,能有效提高风力机叶片效率,效率比标准叶片提高25%以上。In order to improve the performance of wind turbine blades,a bionic design method was proposed based on the good aerodynamic characteristics of the swallow wing.The performance of the airfoil imitating the swallow wing was simulated and compared with the standard wind turbine airfoil using computational fluid dynamics technique.The results show that the bionic airfoil has higher lift coefficient and lift-drag ratio than the standard airfoil.The bionic blade was designed using the airfoil of the swallow.Numerical simulation and experiment for the wind turbine blade were carried out.Results show that the airfoil of the bionic blade has bigger pressure difference between the upper and lower surfaces,which can provide stronger lift.The efficiency of the bionic blade increases by 25%compared with that of the standard blade.
