CABLE-TOWED UNDERWATER BODY DESIGN

Abstract

A general design procedure was originated for towed underwater bodies, based on the longitudinal and lateral dynamics. A practical design was worked out for a specific body to be towed at 45 knots. Characteristics that have a major influence on towed underwater body design are the hydrodynamic coefficients, the damping coefficients, the body drag, the cable tension, and the cable tow-point. The attainable depth and required horsepower depend primarily on the cable, which should be of small-cross-section, laminar-flow streamlined type. Automatic longitudinal and lateral control systems are desirable.
