Predictions of the Steady State Behaviour of an Underwater Towed Sound Generator

Abstract

An underwater towed sound generator, used in sonar research work, was found to be unstable when under tow. Wind tunnel tests were therefore carried out on a model of the vehicle to assess the effectiveness of various modifications designed to improve its stability. Fluid dynamic data from these tests has been incorporated into a computer model of the towed vehicle and cable. This document describes and presents predictions obtained from the computer model for a range of configurational and operational variables.
