Abstract
In order to obtain high efficiency aircraft wings and to improve the energy efficiency in the fields of eco-friendly transportation, the flow characteristics of the aircraft wing were studied with the change of lift-to-drag ratio(L/D) through the CFD analysis. The design process was focused on generating the high lift force and low drag force as the lift-to-drag ratio was increased. In this paper, various dimple patterns, in this case circular-shaped dimple pattern, circular-shaped dimple pattern having embossed conical structure in it, and the dimple pattern having the satellite dimple ahead of it, were numerically designed. Each dimple distance and its position were changed as the artificial conditions. The numerical analyses were conducted by using a commercial code, ANSYS CFX. Numerical result depending on the lift-to-drag ratio distribution was graphically depicted for various dimple patterns.
