IntroductionThe human power submarine is a very
comprehensive project that involves the use of concepts learned from different courses of the mechanical engineering bachelor’s degree. The project consist in the design and analysis of a human powered submarine. By doing this project the institution will increase its participation in international competitions and also will enhance the engineering education of its students.

Problem StatementDesign and simulate a free flooding (water
filed) marine vehicle that fully encapsulates one occupant, that operates beneath the water and uses a propeller system to generate its thrust underwater. The propulsive power of the marine vehicle will be supplied by the vehicle’s occupant at the time it is used.

Hull Design Goal Statement:
Design the hull of the free flooding marine vehicle so that it produces the least amount of drag possible in the water to reach the desired design speed. The vehicles hull should have enough space to encapsulate one person, and the required internal components.
Simulate the vehicle's hull in the water using Computational Fluid Dynamics (CFD) software to understand the behavior of the fluid around it. 10/24

Hull Design Performance Specification:
The hull’s shape must produce the least amount of resistance underwater.
The hull must remain stable at approxi-mately 10 to 15 ft underwater.
The hull design must meet all the safety features required by the International Submarine Races contestant's manual.

Hull Design Performance Specification:
The hull design must be feasible in terms of manufacturing and cost.
The material’s selected for design must resist the stresses developed by the internal components and the pilot’s internal movements.

ConclusionUp to this phase we have proposed some design ideas ,
for the vehicle’s hull and propulsion mechanism and now we are ready to proceed with the analysis and selection phase. In addition we have define some important parameters needed for the hull’s design that are related to the vehicle’s internal components. Once the selection of this parts are completed we can proceed to analyze in more detail the propeller design.
