Abstract

Abstract

The still water resistance towing test is an important method for evaluating the hydrodynamic performance of amphibious unmanned vehicles. Currently, there is a lack of systematic research on the still water towing test procedure and the underlying mechanisms of sailing resistance for amphibious vehicles. In this paper, a certain type of amphibious unmanned vehicle was taken as the test object. Based on its geometric parameters and the defined test conditions, a standardized test procedure was established using a ship model towing tank facility, and the hydrodynamic performance under different towing speeds and different stern flap installation angles was quantitatively characterized. Based on the observed experimental phenomena and the dataset, the effects of variations in speed and stern flap installation angle on sailing resistance characteristics, heave motion response, and trim attitude were analyzed in detail, providing experimental evidence and engineering reference for the hydrodynamic performance optimization of amphibious unmanned vehicles.
