Integrated Ducted Propulsor Concept

Abstract

The Integrated Ducted Propulsor (IDP) is a new concept in marine propulsor design that proposes to integrate the propulsor with the ship's stem. This concept is different from conventional design in which the propeller is designed as an add on device to a specified hull. The principal purpose of this paper is to present the IDP concept by describing a proposed design procedure. The results of calculations of power requirements and cavitation performance are presented to illustrate the feasibility of the IDP concept. The IDP is presented as a challenge to the marine propulsor design community to advance significantly existing design technology.
