Abstract

This paper presents a computer aided approach to Marine Screw Propeller design and its application in combination with "Stator" device based upon a "rational" lifting line methodology for a deeply submerged axisymmetric body. In accordance with the lifting line methodology, the design procedure presented in this paper involves the realistic representation of the slipstream deformation. The slipstream shape is allowed to deform and to align with the direction of local velocity which is the sum of the inflow wake velocity and induced velocity. The calculation of local wake velocities is based on three dimensional flow around the body. As the slipstream deformation is the key parameter in the design of performance improvement devices, therefore the propeller design methodology is combined wi
