WebAug 19, 2024 · Aerodynamic performance is highly dependent on the type of airfoil and the equipment attached to the wing. The effect of the equipment, of course, affects the formation of the lift coefficient, drag coefficient, and lift to drag ratio. Figure 3 shows the ratio of drag coefficient of plain wing, flap δ T = 0°, and flap δ T = 15 WebThe values of lift and drag coefficients of airfoil which is formed by Wing NACA0015 can be obtained through numerical approach, for example by using CFX. The objectives of this study are to simulate and to get the optimum angle of deflection flap

WebThe plot at the right of the figure shows how the lift varies with angle of attack for a typical airfoil. At low angles, the lift is nearly linear. Notice on this plot that at zero angle a small amount of lift is generated because of the airfoil shape. If the airfoil had been symmetric, the lift would be zero at zero angle of attack.
