Hydrodynamic Towing Stability Evaluation of SSN-688 Class Submarines

Abstract

An experimental evaluation was conducted to investigate the surface towing characteristics of SSN-688 class submarines. A 1/22.5-scale model was towed in the David Taylor Model Basin with variations in displacement, trim, metacentric height (GM), towpoint location and with several stern appendage modifications. The SSN-688 class submarine was towed in a stable configuration at speeds up to 10 kn with the sternplanes set to 25 deg trailing edge up, at a trim between 6.0 and 7.5 ft (1.83 and 2.29 m) down by the stern, at a displacement between 5000 and 5650 LTSW, with a GM between 0.75 and 1.10 ft (0. 23 and 0.34 m), with the lower rudder extended 2.25 ft (0.69 m) and with a lower rudder plate appendage attached.
