Passive Control of a Towed Sonar System with Hydrodynamic Lifting Surfaces

Abstract

This paper describes the experimental methodology used to determine and optimize the performance of lifting surface devices which operate in an ill-defined turbulent flow field. The purpose of these devices is to control the aperture of a multiple line towed array sonar system. In addition to the hydrodynamic performance of the lifting surfaces, the deployment and retrieval of the towed array configuration poses a significant technical problem, which is discussed.
