| Abstract: | This paper proposed a new high-speed deformable trimaran , and briefly discussed its advantages and applications. Based on DTMB5415, we suggested a conceptual design of high-speed deformable trimaran. This paper proposed eight arrangement plans for this trimaran and computed the hydrodynamic performance with CFD method and analyzed the wave-making interference and resistance performance for eight different arrangements. Based on it, this paper suggested an optimal arrangement plan for this high-speed deformable trimaran, which can decrease the resistance of per unit weight about 32% |
