HullThe hull is made of many layers of fiberglass with a foam core.Construction of the hull
The hull was constructed using plywood ribs spaced 6 inches apart to create the general shape of the sub. We chose the foam core construction method because would help create a strong righting point as well as a more robust frame.
Safety and Life Support• Safety
The safety buoy is a positively buoyant cutout of the hull. It has been attached to a spool of cord that will act as a dead-man switch.
The positively buoyant hatch will open when the hatch release is pulled.
• Life Support SCUBA Spare Air
Propulsion • Power unit
Consists of a bicycle drive system mounted upside down and a right angle gear. This unit is mounted to an aluminum plate that is fiberglassed to the hull .
• CW-CW Right Angle Gear Transfers the motion from
the bicycle to the shaft.• Shaft
A universal Joint attached to a steel pipe supported by a Teflon bearing with dual propellers attached to the end of the shaft.
Propulsion (Cont.)
• Impeller The impeller is used to
increase the amount of water that is pushed over the blades of the propeller.
• Propeller We took the idea of a basic
2 bladed boat propeller and modified it to suit our specifications. IE- power, input, RPM,
pitch,
Dual Propeller
Controls and Control Surfaces• Dive Plans
The dive planes are controlled by the movement of a curved piece of steel bolted to the shaft that extends from the planed.
• Rudders The rudders are controlled by
a cable with one end attached to a rudder ring on one end and an actuator.
• Stern Planes They are fixed to counteract
the rotational torque from the propeller.
