Thrust per weight ratio, wing in surface effect craft, flying boat, and step positionAbstract
The experiment of Wing in Surface Effect craft A2B and A2C B type for (1 - 2) seaters prototype are the background of this research. The aerodynamic, hydrodynamic, thrust and weight data of these prototypes were already investigated. The best ratio of Thrust per Weight is around 0.4 from this experience to fulfill the liftoff condition from the water surface. The step position on the hull as the theoretical prediction of Wing in Surface Effect craft is made (2 to 10)0 from center of gravity, c.g location to the step position. These formulas have been used to designing the Flying Boat remote control model. The whole process to build the remote control model is shown on this paper. The investigation of the outer wing of Flying Boat remote control model had been done to elaborate the aerodynamic and hydrodynamic characteristic. Included the laser photo camera tracking to 3 D model and Computational Fluid Dynamics analysis have been done also. The three dimensions (3 D) figures are evaluated by CATIA software and then these data results were transfer to the input of CFx Computational Fluid Dynamics (CFD) software. The meshing, pressure distribution and forces distributions during hydro planing of outer wing and pontoon of Flying Boat remote control model have been analyzed by CFx Computational Fluid Dynamics software. The Z force on the outer wing and pontoon showed a good result.Â
