For pure pitching motion, the results show that average drag coefficient decreases as airfoilthickness 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。

As airfoilthickness is increased, the average pressure drag, affected by leading edge vortex is reduced even to be negative, and meanwhile friction has little increase.
由于前缘涡的影响,翼型厚度增加,平均压差阻力系数变小,甚至会出现负值。

According to the characteristics and aerodynamic properties of oblique flying wing, selected two different kinds of te airfoil with relative camber, relative thickness of parameters.
