i might have just cylinders. so may just slap some triangles together into
half of a '12 sided dice' like in roleplaying games. flat surface has
advantage that easy to place small, strong windows centred on trianglular
plates. Ryan's trying to put windows onto rounded surface, seems like alotta
trouble to me. Soon as I help him build his, the skill and parts will lead
to my 'mark1 superheavy torpedo' sub. going for 10' baby TO START- mark2
will be 20'-21' long, 25.5"OD later. Carsten, sir, how is 'world's smallest
sub' measured? weight, displacement, length etc?
Building modular like mk48 torpedo - see tpub.com. Can swap motor
components, frame so cheap, just leave anchored to frame.
The modules will need endcaps made, just making 'geodesic dome hemispheres
from metal plate. May have heavy wall front/passenger, light wall/lotsa
all-the-way-thru-centre support struts, with holes to serve as frame to hold
battery/motor. Mix 'n match with a bolt-on band around 2 touching 'end caps'
- really mid caps, cuz everything but control line is isolated.
May use stubby 'cruise missile' wings so bobs to surface if stops, always
push down.
Any reason wet-cell 'seawater' battery wouldn't work in a lake?
Haven't figured out if want a 'coffin hinge' on cylinder, or have the
see-thru dome window as entryway. Will dictate what hangs low - horizontal
(lying) or vertical (standing) in water. Figured I'd just jettison
engine/battery in pinch, ensure passenger part will go up.
It's a coffin, that makes me kinda nervous...
Figured out the 'pie in sky' mini not micro - using thru-centre of all
cylindrical hull components, jetski style, may try out vectored thrust so
fins rigid, just for stability.
