Aerodynamic Configuration Conceptual Design of Wing-in-Ground Effect Vehicles Based on Box Wing

Firstly, the simplified principles of box wing configuration design are presented based on aspect ratio, taper ratio and relative flying height of wing above the water surface, as well as characteristics and similarity criterions of ground effect. Secondly, the simplified design method of longitudinal stations of box wing is proposed considering the focus of flying height of wing-in-ground effect vehicle (WIG) and principles above. Thirdly, the optimization scheme on engine propulsion type and power deploying is given according to the lift-drag characteristics during the taking-off mission of WIG. Finally, fuselage and tail design of WIG are briefly described, taking its flight characteristics into consideration. Therefore, the analysis above can be taken as the basis during the aerodynamic configuration conceptual design of WIG based on box wing.
