drag turbine的意思|示意

Increasing the lift drag ratio of turbine blade is an effective way for improving turbines aerodynamic characteristics.

提高叶轮机械叶片的升阻比，是改进叶轮机械气动性能的重要途径。

Then kinematics and dynamics of lift-drag-type vertical axis wind turbine of living leaves is analyzed and mathematical model is established.

然后对升阻型垂直轴活叶风力机进行运动学分析和动力学分析，建立了数学模型。
