Figure 9


Fig. 9. (A) Coefficient of lift, coefficient of drag and lift-to-drag ratio vs angle of attack. Lift coefficient (y=0.0617x+4.7421) and lift-to-drag ratio (y=-0.107x+6.8044) have a significant negative correlation with angle of attack, whereas drag is positively correlated with angle of attack (y=0.0209x+0.0925). (B) Coefficient of lift, coefficient of drag and lift-to-drag ratio vs relative camber. Only lift coefficient (y=11.391x+0.4127) and lift-to-drag ratio (y=20.279x-0.5755) have a significant correlation with relative camber.
