Aerodynamic characteristics of a wig craft by numerical simulation
A wing-in-ground effect craft (WIG) that has NACA6409 wing section has been numerically simulated for studying aerodynamic characteristics such as lift to drag ratio, lift and drag coefficient etc. These aerodynamic characteristics were calculated with respect to various major aerodynamic parameters...
