An Investigation of the Hydrodynamic Characteristics of Non-Axisymmetric Bow Shapes for Submarines.

Abstract

This report presents the results of an investigation into the resistance and flow characteristics of a series of unconventional bow forms for a body of revolution submarine. A series of five different bow forms was developed and tested. Three of these bow forms were non-axisymmetric and two were axisymmetric. One non-axisymmetric model served as the baseline and the other two varied in length. The axisymmetric submarine models were designed and tested to provide a control or benchmark shape typical of current practice. The submerged resistance of these two axisymmetric submarines served as a standard against which the resistance of the non-axisymmetric forms were compared. Fluid flow patterns over the non-axisymmetric bow forms were studied qualitatively by observing tufts attached to the models.
