Team Goals

• The team was started in order to bring an
  interest in the STEM areas of education to the
  seacoast of New Hampshire, Maine, and
  Massachusetts
• The team had an aspiration to learn more about
  submarines and engeneering
• Short term goal modify propeller on existing
  submarine
• Long term goal build a complete submarine for
  2013 based on experience and knowledge gained in
  2011

14
Design of Submarine

• The Sub was designed by Wheaton Sub Works. The
  major piece of equipment that we made
  improvements on was the propeller
• The goal of the 2011 race is to get idea for what
  works and implement that on our complete
  submarine in 2013.

15
Safety

• Dead Man Switch
• Made from a bike brake handle
• Quick Release Escape Hatch
• Safety Buoy
• Built in SCUBA

16
Control Surfaces

• The bow, stern plane, and stern rudder
• Are controlled by cable wires and a lever

Propulsion

• Power comes from a cut down bike system
• The sprocket system turns a bevel gear box
• The gear box turns the shaft using a LOVEJOY
  coupling

19
Propeller Design

• The propeller design was based off of the Kappel
  design.
• Testing of the angles were performed in a small
  scale in a basin
• Built by welding students at SST

21
Buoyancy Control

• Pieces of Styrofoam were cut to about 691.2 cubic
  inches to balance out the propeller
• 25lbs (1 in3/ 0.036127 lbs per inch3)

23
Testing

• The propeller design was tested in a small scale
  basin in which we tested the speed at which a
  boat equipped with a specific pitch of blade
  traveled the distance changing the pitch to find
  the best angle to come up with the most effective
  pitch
• There were two test dives in the UNH dive basin

24
Training

• 8 Dives and lessons
• 2 were with submarine

25
Budget

• The submarine was borrowed and about 100.00 was
  spent on miscellaneous parts such as paint,
  handles for the cradle, high performance putty
  compound, etc.
• The propeller was made out of scrap metal donated
  to the team
• Large grant from Portsmouth Naval Shipyard for
  work on base.

More Information on Our Team

• We all came together 6 months ago from different
  schools.
• Nobody knew each other.
• In 6 months we have accomplished many things.
• In part it was due to great leadership and
  initiative from our 2 leaders.
• We are all here because we made the decision to
  do so. Not for just for school credit.
• We worked every Thursday night for the better
  part of 6 months to get to where we are today.
• We have created friendships and gained a great
  deal of knowledge.
