Abstract:
The purpose of this study is design and simulation of morphing flap for a slotted airfoil to reduce drag and increase lift. Increasing lift results in a smaller flap for the same lift, resulting in less weight and less drag. Drag reduction due to morphing nature causes growth in aerodynamic efficiency. In this work, a flap designed for 0.2 and 4,700,000 Mach and Reynold numbers, respectively. Our simulation was performed using ANSYS FLUENT flow solver and POINTWISE for grid generation. Here, morphing has been applied by changing the flap mean camber line and slots, so that they have minimum interferences with the flow. For this purpose, the flap mean camber line was discretized and various flap geometries were produced. In this way, compared to common flaps, lift coefficient is increased, drag coefficient is reduced (three times), and aerodynamic efficiency is improved (five times).
