You've probably all seen these pictures of "The smallest Russian
Submarine"
Got me thinking, he's got some sort of knob on the top of his dome, for
what purpose I don't know. With a blown dome where the apex is half the diameter
of the
base & is the weakest point, (provided the inner flange bend is
reinforced) could it be strengthened by either building up with a methyl
methacrylate monomer (liquid acrylic) & fiberglass or carbon fibre, or
tipping the dome upside down into a mold of liquid acrylic.
The bond should be 100% & it's under compression so won't tear apart. (
would need annealing)
The blown dome I'm having made is 25mm thick, so at the apex should be
12.5mm thick.
At 25mm it has a crush depth of 3,300ft at 12.5 it has a crush depth of
1,051ft. I'm not sure wether it gets thinner in a linear progression
from base to apex, but if it
did & was reinforced half way down to the 18.75mm thickness it would
increase the crush depth to 2,425ft.
I'm not considering going down deeper but just increasing my margin of
safety, & others after me that can't afford a cast dome.
Any thoughts on this one?
Alan
