Abstract
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 i.e. the ground clearance, the angle of attack, the wing and the endplate type. Pressure field around the craft were studied to find out the nature of vortex under different conditions. Results of the simulation were verified by published experimental results. The dihedral wing and the endplate have a positive influence on the lift-to-drag ratio, also dihedral wing improves the efficiency of WIG craft by increasing lift. Comprehensive numerical simulation results can be very handy to understand the aerodynamic characteristics of a WIG craft which are influenced by different aerodynamic parameters during ground effect. Keywords: Wing-in-ground effect, NACA6409 ,Endplate ,Tip vortex , Lift-to-drag ratio
