Modeling of water-jet propeller for underwater vehicles

摘要

Propeller is the most important part in a underwater vehicle system. An accurate modeling of the propulsion system is necessary. In this paper, we discuss about the modeling of water-jet propeller which will be used on a spherical underwater vehicle. By considering the ambient flow velocity and the incoming angle of the flow, we designed an experiment, and obtained the dynamic model of the water-jet propeller.
