Mathematical formulation of body of revolution applied to AUV's shape

Abstract

This paper summarises the investigation of the mathematical shape formulation that can be applied to the AUV’s hull-form. Firstly, a shape with rounded nose and rounded end is presented. The influence of independent variables towards a meridian shape is discussed. Body shapes of various parameters’ change are addressed. Secondly, the design of a hull shape can be divided into three sections, namely, forebody, midbody and afterboday. This allows to modelling a variety of hull’s shapes. It is a combination of different curves with different constraints. There are four choices of curves: rounded curve, pointed curve, cusped curve and flat face curve. The hull-form shaping by those lines’ equations later can be adopted for optimisation the low-drag hull shapes. This study can give a preliminary idea for the efficient design for AUV
