Experimental Determination of the Hydrodynamic Loading Functions for the T-5 Trailing Fairing.
Abstract
The Naval Ship Research and Development Center (NSRDC) established a broad research project under the Variable Depth Sonar Exploratory Development Program directed toward the development of improved experimental and analytical techniques for predicting the steady-state characteristics of cable-towed systems. The project, to be completed in two phases, consists of (a) basin tests to acertain the hydrodynamic loading functions of a faired cable and (b) sea tests to verify and to correlate basin test data and theoretical predictions with sea test data. This report is the subject of the first phase of the project dealing with the basin tests to determine the loading functions. The report describes the faired-cable model, the towing dynamometer, and the test procedures; give sample curves of normal and tangential forces versus submergence for various speeds; presents tabulated loading functions; gives plots of the normal and tangential loading functions versus cable angle and a plot of drag coefficient versus Reynolds number; and provides the mathematical expressions derived for the loading functions.
