Abstract
Wing leading - and trailing-edge flaps are usually deployed13; to improve the lifting ability of wings, especially13; during takeoff and landing. In recent times, however, these13; flaps have been used also during maneuver conditions to im-13; prove the aerodynamic efficiency (LID). Some examples of13; aircraft usingsuch devices are F-4E, F-5E, F-16, F- 18, etc. During a maneuver, the flaps automatica!ly follow a predetermined deflection schedule which is a function of Mach number and angle of attack. The flap deflection schedule is mainly determined through extensive wind-tunnel tests. 13; In this paper, a simple analytical method based on linear theory is developed to determine the optimum flap schedule13; for both leading and trailing edge flaps.
