airfoil drag coefficient的意思|示意

For pure pitching motion, the results show that average drag coefficient decreases as airfoil thickness is reduced.

在低雷诺数条件下，对于纯俯仰运动，随着翼型厚度的减小，平均阻力系数也变小。

Also the effect of different ice shapes on lift and drag coefficient were assessed. The results indicate that the glaze ice has the most adverse impact on airfoil aerodynamic performance.

另外还计算了不同的冰形对机翼升、阻力的影响，结果表明瘤状冰对机翼气动特性的影响最大。
