Development of an Interface System for the Design of Submersible Internal Arrangements and Hull Forms.

摘要

This report presents the results of an investigation into the development of an interface system for the design of submersible internal arrangements and hull forms. The research and development were conducted as a Trident Scholar project at the United States Naval Academy. The design process was founded on what is being called concurrent design methodology. The development of the process involved the interfacing of commercially available geometric modeling and CAD tools with analytical parametric methods of marine vehicle drag analysis. The interfaced design tools were then employed to design a human powered submersible in order to validate the efficiency of the particular concurrent design processes used in this project. The submersible vehicle's design requirement were established by the Biannual Human Powered Submarine Race committee. To provide a basis for relative performance comparisons, previously constructed and raced submersibles were remodeled using the system's CAD tools in order to be evaluated and compared to the new design generated by this project. The methods of design and analysis are detailed in this report. The report also contains a new program that was created to extract vehicle hull form characteristics from geometric data. The results of this project have shown probable reductions in vehicle drag over existing human powered submersibles.
