ABSTRACT
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.
