This is draft render of the UCSD Human Powered Submarine team’s hull, control surfaces and propulsion boom/fin used for fluid dynamics testing. The hydrodynamics of the submarie has been improved from the 2016-17 hull in several ways.
The previous hull had trouble with steering because the control surfaces were placed too close to the center of mass. To improve this the hull has been extended out by 18” with a narrow portion at the end. Moving the propulsion system backwards will allow for more effective stability and steering from the control surfaces.
In order to make this extension without adding an excessive amount of mass to the hull the propulsion fin will now be powered via driveshaft. This allows power transmission through a narrow part of the hull. Another reason for the extension is to move the propulsion fin outside of the wake of the submarine which improves efficiency.
