WebConsider the lift curve slope of an airfoil used for a lifting surface (a wing, HT, or VT). As shown in Figure 9-97, the downwash behind the wing and corresponding upwash in front of it “tilt” the undisturbed air, reducing the geometric angle-of-attack, α, by amount α i (called induced α). The resulting angle-of-attack is called the effective α (α e). Web28 jul. 2024 · The induced drag coefficient Cdi is equal to the square of the lift coefficient Cl divided by the quantity: pi (3.14159) times the aspect ratio AR times an efficiency factor e.
