Abstract
The Defence Research Establishment Pacific (DREP) is studying various methods of remote mine-hunting. These methods involve the use of a drone vessel towing a side-scan sonar. The sonar is housed in a tow-body (towfish) and deployed to a specified depth via a cable and winch. A hydrodynamic depressor or clump weight is required to force the towfish down. The performance envelope of a tow system, primarily depth-to-scope ratio vedrsus speed, is tedious to calculate, but is an essential, and often iterative, part of the design process. This report contains the first non-dimensional analysis of a cable-towfish system. The contour plots presented here allow the performance of two-dimensional steady-state systems to be predicted without further computer modelling.
