摘要：

In order to investigate the resistance performance of an ultra-high-speed aerodynamically alleviated marine vehicle (AAMV), finite volume method (FVM)-based computational fluid dynamics (CFD) software STAR CCM+ is used to simulate the forward motion of this vehicle. The calculated results are validated as they reach good agreement with experimental data. Comparing the motions of models with and without aero-wings, the hybrid aerodynamic and hydrodynamic mechanism of this novel hull is discussed. Study is subsequently performed that how step configuration, spray rail and deadrise angle act on hull behavior and resistance. The results show that models with double steps and spray rail possess better resistance characteristics at high speeds, and planing surface with variable deadrise angle could further improve the overall navigation performance.
