DESIGN AND CONSTRUCTION OF A SUBMARINE HULL. A RESEARCH PROJECT MATERIAL ON MECHANICAL ENGINEERING
This project entails the systematic approach used by the authors to design and construct a submarine hull which is watertight to at least a depth of one meter. A NACA 6- series airfoil shape was used because of its emphasis on maximizing laminar flow, owing to the fact that resistance can be reduced by maintaining a laminar boundary layer. Included is detailed literature research acting as a basis of the design, results from resistance test and other relevant information. Results obtained from final calculation showed L: D ratio as 5.0 and the drag at 2.57m/s to be 354.022N. The results were conclusive as it confirmed the hull to have a good hydrodynamic performance with respect to the propulsive power. This project has allowed the team to gain a better understanding into the application of fluid mechanic principles in a real-world environment.
