Yes our design is essentially that of a torpedo. The original design was self-levelling and had other eccentricities but given the short build period we have to keep it simple.

1) The project is for a miniature sub: it won't be scaled up. 2) There are no electronic control systems in it seeing as we only have 8 hours to build the thing, so we are planning to design it to have neutral buoyancy and steering-wise we've got an impeller-style design like a torpedo so...

Hey again, good to see so many of you helping us out. In response to Entropy's post (#21) we assume the craft must be underwater throughout the run but in terms of steering the craft is allowed to bump its way along the sides. In response to the "rocket" fans out there: the...

Thanks for the rapid responses. I should have included more specs in my question- my bad 16 gram cylinder of liquid CO2- energy source The purpose of the craft is to beat all rivals in a 10 metre sprint in a shallow tank: economy only needs to be considered in the sense that we shouldn't run out...

Hi all, I'm in a group of undergrad engineering students who've been given the task of designing and building a 345mm length submarine which runs on a CO2 canister. We have chosen an oscillating CO2 engine as the power-plant and it runs to a prop. We've modeled the initial designs on 3D...
