A numerical analysis of hydrofoil operation near the water surface and development of a method to calculate the HYSUCAT dynamic performance in the conceptual design phase

Abstract

Present study is to attain a method for predicting hydrodynamic performance of the HYSUCAT crafts at the conceptual design phase. Numerical results were used to validate analytical equations of hydrofoil operation just beneath the water surface. The pressure distribution and forces acting on E654 Eppler foil section were calculated. With composing foil calculations and planning catamarans hull analytical calculations, a performance prediction of the HYSUCAT boat is done in calm water situation. Resistance reduction rate of 30 percent attained for a sample catamaran model "Ghazal".
