Submersible Maneuvering

Abstract

The wake steering shroud is a method of steering marine vessels which uses a shroud surrounding a propeller to accelerate the fluid and cause a low pressure region inside the shroud downstream from the propeller. The shroud shape is such that the wake is attached to the inside of a shroud under these conditions. Control ports are provided in the side of the outside and this causes separation of the wake from the inside of the shroud downstream of the propeller. The resulting separation causes an asymmetrical pressure distribution inside the shroud and provides a radial steering force. The concern of the report is to gain a better understanding of this phenomena and develop the concept to the point where it can be applied to marine vessels for steering and propulsion.
