I have a little
challenge here that is a volunteer opportunity if anyone would like to design a
cool part that's a little beyond my present capabilities.
Background
info:
My project is a
1 atmosphere "flyer" with a collapse depth of 3K feet, roughly a la Deep
Flight for those of you familiar with that sub (although on a very different
budget and very low tech). This is a design in which hydrodynamics are
important. Basically its somewhat like an aircraft, with wings amidships, V tail
"ruddervators", and two thrusters astern. The thrusters are tucked in
behind the hull, and will need intakes. I've completed the pressure hull.
The wings, ruddervators, and thrusters are all on, and I'm just awaiting
some custom connectors to finish the external wiring and
tubing.
Here's the
challenge:
I need to design a
fiberglass fairing for the stern. I think this really has to be a 3D CAD effort,
because compound curves, intakes, etc. make it simply too hard to visualize
in 2 dimensions. If any CAD guru out there would care to take this on just for
fun, I can provide 2D CAD diagrams of the underlying structure to be faired, as
well as pictures of the actual built project. For inspiration I can provide
detailed close-ups of Deep Flight's stern, although this design will be
substantially different. Anyone who does this gets credit on the eventual sub
homepage, but I'm afraid I can't really pay for the job. Incidentally, I do
plan to eventually put all CAD diagrams, bills of materials, etc. up on a page
for free... but only once the sub is known to work.
Any
takers?
