چکیده

In this paper, after studying different Drag reduction technologies and HYSUCAT development necessity, a research has been done to attain a method for predicting hydrodynamic performance of the HYSUCAT crafts at the conceptual design phase. On the other hand, as the first step, 4 hydrofoil sections were chosen to be calculated by numerical calculation software called Autowing2.31 . Then, 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 foilsection were calculated. Finally, with composing foil calculations and planing catamarans hull analytical calculations, a performance prediction of the HYSUCAT boat is done in calm water situation. As a result, Resistance reduction rate of 30 percent attained for a sample catamaran model Ghazal .
