Tests and Investigations of a High Speed Towed Sonar Cable

摘要

A program involving mechanical tests and technical evaluations has been performed on a series of high speed faired towing cables and cable components. The mechanical tests involved torsion tests to determine centers of rotation and torsional rigidity (JG), tension tests to ascertain centers of tension, and a simulated drum winding test of a partially segmented faired cable which has been successfully towed at high speed in Lake Washington. Construction of hydrodynamic models was performed to permit future conduct of lift-drag tests to be sponsored by the U. S. Navy Electronics Laboratory. A study conducted upon the direct analogy-analog computer (passive analog) was to examine the static and dynamic stability of faired cables and to attempt to provide guidance for future cable designs.
