Abstract : A wing in ground effect (WIG) vehicle, the body of which is a low aspect ratio airfoil. Soft end plates allow for proper sealing of pressure below the wing while preventing the transmittal of wave action forces to the vehicle. Fin rudders and a dorsal fin provide turning control. Efflux from the propulsor engines can be split to flow both over and under the wing so that the vehicle will be capable of both rapid movement and hover over both land and water. Two designs are disclosed providing this vehicle with the ability to jump out of ground effect mode to avoid obstacles appearing in its flight path. (Author)
