WebDrag polar is the name used by aerodynamicists to describe how Cl varies with Cd, whether by a diagram or an equation. Drag polars do not use angles of attack explicitly, though drag curves and lift curves do. This is covered in the opening para. I've reverted the title, since this sort of plot/ equation is the subject of the article. WebNov 5, 2015 · With flaps up, the airplane’s best L/D speed (best glide speed) is found at the bottom of its total drag curve. As you’ll recall from ground school, the total drag curve is the combination of a decreasing parasite drag curve (as airspeed decreases) and an increasing induced drag curve (as airspeed continues to decrease).
