Re: [PSUBS-MAILIST] Diver Lockout.... serious question here!!

Serious DLOs have dive chambers separate from the crew compartment. And as for your thrusters, in my experience AIR transmits heat faster than oil. How deep are you building these things for? HBOI, for instance, runs aluminum cans and PM motors in air to 3000 feet, with no real problems. The commercial units that Nuytco uses ARE oil filled, I believe, but have a higher pressure rating, and no reduction gear.

I've got into some pretty serious questions lately......and I've done a 
little reading about diver lockout (archives), but the archives raised a 
question.

If you have a 1 atm sub, with a diver lockout........how do you lock a diver 
back in?

Are there any 1 atm subs with a lockout?

If there are......if the lockout has been pressurized to the outside 
pressure........what method is used to depressurize it back to 1 atm? 
(these questions are redundant I know)

And  the last....the important one.....is this on the dangerous side? If you 
depressurize to fast......the bends.

I was reading about the nice sub.....(the Krata I think.....please don't 
quote me ....I've had a very long two days)......but I didn't notice if it 
was 1 atm or not.

Some one learn me on this.   :-)

(Hey....at least I know what a VBT is for now.)
