Re: [PSUBS-MAILIST] hull test
Silky,
A sub hull is a lot of money and work to loose if you lower it to the bottom
for a test on a line, with no person in it, but it's the safest way to test
a personal sub. Of course testing in a pressure chamber would be even
better but most small sub builders don't have or can't afford this luxury.
Even with the risk of loosing the sub because of a simple line malfunction,
a deep water test of the hull should be done unmanned. After all, it's a
test to see if you'll be safe diving in it.
A sub the size of Carsten's is not in this category. I can only imagine the
feeling in Carstan's gut when he does his tests, manning it himself. I have
a lot of faith is the calculating skills of a man that can design and build
such a project and I'm sure he's pretty confident he will have no problems
he can't solve as he goes, but we all know there is considerable risk
involved.
P-subs should only be test proven unmanned!

Subject: [PSUBS-MAILIST] hull test
hey,
iv been following this thread thinking, guys if your gona do a physical
test then its a good idea to stick to the rule of doing a fair test if u
havent done your calculations correcty then it would b better to have your
hull implode without u in it. also if someone sends me a link to some hull
calculations stress spread sheets thn ill try making u a program to aid
you in hull design / calculations, that would be a good exersise for me
and may also help someone getting a ruff idea of what hull design
involves.
easy...
silky
