<p>Submarine designs have traditionally been evolutionary, with each new design being more capable than the last. Issues like speed, depth, and combat/weapons systems have dominated the design process because of concerns with the increasing capability of Soviet submarines. Only cursory attention has been paid to affordability. As a result, the SEAWOLF submarine is estimated to cost approximately twice as much as an improved-LOS ANGELES Class submarine (its predecessor).</p> <p> The combination of a reduced Defense Department budget and increased unit costs is projected to result in an Attack Submarine force level of less than 40 ships over time as opposed to current force levels of 90-100 ships. The Navy has on occasion stated that 60 submarines is the minimum needed to meet its mission requirements, which have changed with the decrease in the Soviet threat. Accordingly, the current Navy focus is to explore ways to reduce unit submarine costs to less than half of SEA WOLF.</p> <p> This project will examine the submarine from a Life Cycle Cost perspective starting with the definition of need, mission definition and requirements, trade-off analysis and cost allocation all resulting in a conceptual submarine design that meets the cost target of 50 percent for acquisition and 75 percent for operations and maintenance relative to the SEA WOLF submarine program.</p> / Master of Science

A preliminary design of a local area network for a submarine overhaul facility is developed using System Engineering concepts. SOFLAN, the Submarine Overhaul Facility Local Area Network, is necessary to provide more timely and accurate information to submarine overhaul managers in order to decrease the overhaul time period and become more competitive. The network is a microcomputer based system following the Ethernet and IEEE 802.3 standards with a server .. client architecture. SOFLAN serves thirty five users at various offices and overhaul facilities throughout the shipyard. The network provides a medium to transmit information between and across various organizations. Applications resident on the network include a database management system, file transfer, word processing and electronic mail. SOFLAN replaces the existing manual systems' currently is use at the shipyard. The system life cycle is twelve years from development to phase-out with a cost over the entire life cycle of approximately two million dollars. / Master of Engineering

An investigation of the flow field during eject of a cruise missile from the launch tube was undertaken using a "cold" flow simulation. A facility was developed whereby various design changes in the missile ejection apparatus, denoted the vertical support assembly, could be quickly and easily assessed in terms of the relative effects on the flow field. Flow visualization techniques using fluorescent dye allowed for documentation of flow patterns in the baseline configuration, such as backflow, jetting, and recirculation regions, as well as for the location of several potential hot spots. The mixing of the fuel-rich gas generator effulent and the air in the launch tube was assessed by thermocouple measurements; warm water was used to simulate the exhaust while ambient water represented the air initially contained in the launch tube. The results have shown that air is inefficiently mixed in large portions of the vertical support assembly volume. However, strong flameholding zones are established in the region vacated by the accelerating missile, where it is believed that secondary combustion could occur. The flow field characterization has shown that considerable improvements to system performance should be possible through geometrical changes to promote more efficient mixing. / M.S.

The effect of fin and jet vortex generators on the crossflow separation of a 688 class submarine in a turning maneuver was studied. The vortex generators are located on the top and bottom centerline of the submarine. The intent of the vortex generators is to improve turning performance by changing the hydrodynamic forces incurred from crossflow separation. Performance of the jets and the fins are compared. Oil flow visualization and force and moment measurements were used as the primary diagnostics in determining the effectiveness of various vortex generator configurations. The fins were found to be very effective in delaying cross flow separation, while the jets were less effective. In addition, the oil flows revealed the importance of locating vortex generators near the bow and the critical role the sail plays in the fluid dynamics near the submarine. Overall, the fins were found to be viable as a concept for flow control, while the jets were less attractive. / Master of Science
