Summary

The Gurney flap is a simple device that can be easily attached to the pressure surface of an airfoil. The control effects of Gurney flaps on airfoils, wings, and aircraft are introduced, indicating that the Gurney flap can effectively increase the lift coefficient. Thus, it shows significant ability to shorten the takeoff/landing distance of aircraft. In addition, the influence of different parameters is compared and the control mechanism is revealed. Finally, some suggestions for engineering applications are given, as it is expected that Gurney flaps could be actually used in the near future.
