Innovative gearbox design
Propeller designed 900 rpm is reachable
Lower drag coefficient with the use of a shroud
Less power loss due to turbulence

Unefficient fin designFins were too fragile
and broke easily
![Page 9: Archimede V](https://reader036.fdocuments.net/reader036/viewer/2022062519/56814c54550346895db96bf7/html5/thumbnails/9.jpg)
Hull design verified using finite element methods. The hull not being symmetrical ameliorations are possible.

Fin designSubmarine overall shapeSubmarine total frontal area due to previous pilot size (6’2” – 100 kg)

Stronger fins, less breakable
Bigger bonding area to the submarine
Longer fins on submarine total length positively affecting submarine stability because of the fixed front part

13
Smaller directional fins to increase control and steering of the submarine
More efficient movement of the fin directly affecting submarine stability in water

2007 nose was entirely fiberglass and very fragile
![Page 16: Archimede V](https://reader036.fdocuments.net/reader036/viewer/2022062519/56814c54550346895db96bf7/html5/thumbnails/16.jpg)

2009 nose design has not changed
Nose failure in previous competitions encouraged us to reinforce it
Kevlar coated for 2009 which increases total mechanical resistance

Hull made out of a layer of corecell between two layers of fiberglass
Hull counterpart made out of foam
Mold then made out of that counterpart

Shroud made of fiberglass
Designed in accordance with the propeller and submarine
Gives better and more concentrated flow of water

Propeller – Designed by specialists (Nautican) Machined at École Polytechnique de Montréal
Optimized for 900 rpm in accordance to 1:8 gearbox ratio

Gearbox made out of aluminium plates
Gears from Boston gears made of steel
Ratio of 1:8 connected to bicycled pedals with clips
