Afficher plus [+] Moins [-]Non-Pressurized Manned Submersibles (NPMS) have proven their utility in warfare for centuries, demonstrating an unmatched combination of simplicity and versatility in both declared conflicts and undeclared, covert operations. Today, the SEAL Delivery Vehicle (SDV) Mk8 Mod1 remains the United States military's most reliable and clandestine method for deploying special operations forces (SOF) to and from the maritime environment. However, the undersea missions of tomorrow are of increased duration, difficulty, and complexity. In their existing configurations, many current NPMS are unable to meet these growing demands, and leaders are forced to seek alternatives which close the gap between current capabilities and future requirements. This thesis is strictly an academic effort intended to demonstrate that through deliberate, cost-effective modifications and a systematic reorganization within their existing hull form, NPMS of today can meet the mission criteria of tomorrow. Moreover, performance objectives such as increased payload, combat radius, and enhanced mission scope can not only be achieved, but in a timely manner and at a reasonable price. To best illustrate the effectiveness of this approach, this document follows the methodology and final results of a thirteen month "optimization" study of the SDV Mk8 Mod1, and will offer a comprehensive analysis and comparison of nondimensional design parameters between the final product and her predecessor.
