An Investigation into the Performance of Non-Body-of-Revolution Submarines-DTMB Series 66

摘要

For more than fifty years US Navy submarines have used a body-of-revolution (BOR) hull design. Even the ballistic missile submarines have used a BOR hull design with the addition of a deck to cover the missile hatches. With the CNO's recent emphases on improving the ocean interface, and developing modularity for the submarine's payload (OPNAV N875, 2000), the possibility of using a non-body-of-revolution (NBOR) has been suggested. With this type of hull a submarine could be developed that would allow dockside payload module changes including, but not limited to: ballistic missile modules, conventional missile modules, ASDS vehicle modules, SDV modules, and mine modules. The navy has very little experimental data on non-body-of-revolution hull forms and the little that is available has no systematic variation. The Maneuvering and Control Division of the David Taylor Model Basin, Naval Surface Warfare Center (NSWC) is developing improved techniques for quantifying and predicting the maneuvering characteristics for NBOR submersibles. Two distinct areas of work are described in this paper: 1-Parametric captive model experiments to determine the effects on stability and control due to geometric changes; and, 2-A study to determine the effects of L/D on the BOR series of models.
