SpletTrailing-Edge High-Lift System. Plain flap - Plain flaps are formed as the pivoted rear section of an airfoil. The principle used in a plain flap is the increase in airfoil camber. Flap length equals around 30% of the chord. Split flap - Split flaps increase the lift as same as plain flaps. However, they are not used, as they produce drag.

The article linked in your other answer says that the thicker flap has a larger leading edge radius which will delay separation, allowing more lift. Also, it offers more torsional stiffness, which keeps the number of flap tracks low. – Peter Kämpf. Jan 27, 2024 at 22:17. Splet15. mar. 2024 · The trailing edge flap used in this study is stationary, i.e., sealed gap flap. Since XFOIL does not assume any gap between the flap and the airfoil, the flap is only accounted for the modified lift and drag coefficient tables that result from the XFOIL …
