Team Leaders Ms. Young Town - Rye Position: nuclear engineer at Portsmouth naval shipyard Current interests - hanging out with my children; improving our country's competence in STEM subjects Future goals - put siding on the house before the snow flies and work to make America a great place for my grandchildren to raise their families. Mr. Messa State: Maine School: Engineering Teacher at Seacoast School of Technology Current interests: hiking, building things, engineering and most of all teaching

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

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.

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

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

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 Propeller Design

Buoyancy Control Pieces of Styrofoam were cut to about cubic inches to balance out the propeller 25lbs (1 in 3 / lbs per inch 3 )

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

8 Dives and lessons 2 were with submarine Training

Budget The submarine was borrowed and about $ 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.
