Aerodynamic Design of Wing in Ground Effect Vehicle for High Flight Stability

Abstract

In recent years, ground effect vehicles are focused again for solving environmental problems and high-speed maritime transportation. Therefore, we have been researching the design of the small air vehicle with high Lift-Drag ratio in ground effect. In this paper, the effects of the wing section shape and dihedral angle on the aerodynamic performance of the ground effect vehicle are discussed. In addition, the effect of the position of the center of gravity on the pitching stability is discussed.
