Using Wing-In-Ground effects, a WIG craft can achieve high lift/drag ratio. The craft is more flexible and efficient than the traditional ship in business transport or military-supply transport. It offers a new low-fuel-consumption alternative for a country with vast water areas or numerous islands. When the flying wing ship increases the flight altitude, the aerodynamic force center forward motion, causes to gather the torque suddenly to increase, produces gains ground the phenomenon, or the motorized ship when is separated from by the water surface, the resistance suddenly reduces, the speed suddenly increases, the lifting force greatly increases along with it, in order to maintain the fuselage the longitudinal stability, avoids creating the motorized ship supinely to turn out of control This thesis uses numerical methods to study the influence of the Wing on the Horizontal Tail under Ground Effect. This study concentrates on the lift coefficient and lift/drag ratio. The parameters we choose include the flight altitude, the distance of the wing and horizontal tail , the height of the wing and horizontal tail.
