| Summary: | Basic concept of aircraft wing design is based on airfoil section. Time flies, evolution in aircraft wing design shows the desire of mankind to improve the speed, agility, maneuverability of an aircraft. It is proven that aircraft with delta or double delta wing design fulfill this desire. Basic concept of delta wing is triangular planform of the wing that same with the Greek symbol (Δ) and double delta wing is delta wing with a ‘kink’ or leading edge extension. This research aims is to obtain aerodynamic characteristic (Cl, Cd) of double delta wing using computational fluid dynamic and compare the result with wind tunnel experiment. In this work, the geometry of the double delta wing used was constructed using 2 x 106unstructed mesh elements. Turbulence model that been used in this research is k-ω turbulence model. The simulation was run at Reynolds Number of 1 x 106 and 2 x 106 and with variation of pitch angle from 0° to 20°. |
