Analysis and Research on Hydrodynamic Characteristics of An Ultra High Speed Amphibious Vehicle
Taking the M-shaped body of an ultra high speed amphibious vehicle as the research object, the hydrodynamic characteristics of its high-speed gliding state on water were analyzed and studied using computational fluid dynamics ( CFD) . The focus of this study is on the flow field, resistance, heaving, pitching and its torque. The results show that the resistance of the vehicle reaches its peak at a speed of around 35 km/h, and it is completely in a coasting state at a speed of 50 km/h; And its heaving and pitching characteristics indicate that the vehicle can navigate steadily at various speeds.
