Hydrodynamic Design and Analysis of a Towed Environmental Sensor Vehicle

Abstract

A hydrodynamic vehicle design analysis of a towed environmental sensing system was conducted. The primary thrust of the analysis was to determine the towed vehicle geometry and mass characteristics which best meet the depth-keeping and stability requirements. The effects of the tow cable, depressor, and tow ship were also examined. The design requirements, initial vehicle geometry, the effects of geometry modifications, and the final vehicle geometry are presented. Longitudinal and lateral stability are presented as a function of geometry. Towed vehicle response is predicted for typical seaway and ship motion forcing functions, and the system tow performance is presented as a function of speed and depth. (Author)
