Abstract

Abstract

The still water resistance drag test is an important method for evaluating the hydrodynamic performance of amphibious vehicles. However, existing research lacked systematic description and verification of the test process and mechanism. A specific high-speed amphibious vehicle was selected as the research object. Standardized test procedures were developed using professional equipment, based on geometric parameters and predefined test conditions. Hydrodynamic performance was quantitatively measured at varying drag speeds and stern flap installation angles. Test observations and datasets were analyzed to determine the influence of speed and angle variations on sailing resistance characteristics, sinkage motion response, and trim attitude. This provided an experimental basis for hydrodynamic optimization of amphibious vehicles.
