Computational Fluid Analysis for High Lift on Multi-Element Airfoil Used in Civilian Aircraft

The choice of high-lift system is crucial in the preliminary design process of a subsonic civil transport aircraft. Even a small increase in high-lift system performance can make a big difference in the profitability of the aircraft. A better understanding of high lift flows is needed to continue increasing the performance of high-lift systems while decreasing their complexity. The present work involves the design and aerodynamic analysis USING ANSYS CFX 14.5 of an multi-element airfoil with leading edge slat and trailing edge flap mostly used in transport aircrafts. Airfoil designed in 2D and 3D and analyzed in 3D for lift and drag coefficients at three different flap angles enhancing for the high lift.
