Abstract
nAn Underwater Vehicle (UV) is designed to function underwater and range from an Autonomous UV to a submarine. The main difficulty that UV designers face is minimizing the weight of the pressure hull to maximize payload and propulsion velocity while reducing construction cost and time by employing appropriate material and design approaches. Herein, we examine applications geared toward submarines as well as the creation and development of an analytical model for the preliminary structural design of hull of underwater vehicles focusing more on submarines. Our implementations have been with an objective to make initial design easy, reuse-able and robust incorporating best design parameters and buckling theory which acts as moonlight for advanced research. Our approach is modular, where in module 1 user can input the desired design parameters of submarine and module 3 gives the required output with proper validations and module 2 hosts the analytical simulation. Presented approach is simple and it can be easily implemented in any of the existing commercial software solution systems, e.g. Matlab*TM.
