High lift leading edge devices have been the subject of research and development since as far back as 1917 1. Current leading edge device technologies. ![]() ![]() Thus the optimized NACA2412 three-element airfoil gives good aerodynamic performance. flow control to delay leading edge separation from the airfoil, which in practical terms will allow the removal of the leading edge slat devices. The obtained results have an accuracy of 1.09% for maximum coefficient of lift and 0.4% for landing condition respectively. A two-dimensional CFD (computational Fluid Dynamics) analysis performed on best three element airfoil using SolidWorks Flow Simulation tool with variation in aerodynamic parameters as lift and pitching moment. The optimization is achieved with four defined configurations for each high lift device and then compared their results with each other to find the best configuration here the best performance refers to maximization of section coefficient of lift. This article focuses on the optimization of high lift devices such as leading edge slats and trailing edge flaps. Hence, attention is to be given to the optimization of these devices to increase their efficiency and performance. ![]() The performance of these high lift devices depends on various parameters, among which the geometrical or positional parameters are one of the most important as their influence is very prominent on the aerodynamics of the wing. Currently, various high lift devices are being employed in the general aviation industry.
