DESIGN STUDY AND EXPERIMENTAL PROGRAM FOR A HELICOPTER-TOWED SONAR SYSTEM

Abstract

Towed sonar systems in the past have been flow noise limited at speeds above 20 to 25 knots, resulting in low search and limited attack capabilities. This report reviews recent developments in the field of hydroacoustics and hydrodynamics associated with a helicopter-towed sonar system that points to major improvements in flow noise control as well as stabilized highspeed towing at speeds as high as 60 knots. These innovations, when incorporated into a complete HSS-2 helicopter towed system, will present an effective search and attack capability against the high-speed submarine. (Author)
