Hydrodynamic Towing Evaluation of SSN-637 Class Short-Hull and Long-Hull Submarines with Modified Bows

Abstract

An experimental evaluation was conducted to investigate the surface towing characteristics of short-hull and long-hull SSN-637 Class submarines with modified bows. A 1/16.667-scale model was towed in the DTRC shallow-water towing basin, varying towpoint location, metacentric height (GM), displacement, trim and sternplane/rudder plate configuration. The short-hull and long-hull SSN-637 Class submarine with modified bow was towed in a stable configuration at speeds up to 10 knots (5.14 m/s) full-scale with the sternplanes set to 25 deg trailing edge up, at a trim of 6 ft (1.83 m) down by the stern, at either displacement, at either GM, with either towpoint, with a lower-rudder plate appendage attached.
