Re: [PSUBS-MAILIST] Typhoon dry ambient



Hi, Bill . . .

Since your design is ambient, will you be completely dry all the time with the water level always below you?
 
Completely dry.  The water will neither enter nor be exposed to the interior in any way.  The cockpit will be built up somewhat  [glass over ply] to compensate for at least some pressure differentials, mostly from large wave action at the surface.  Twelve foot seas will pop your ears somewhat, but, I'd rather not see my cabin walls oil-canning.  Momentary deltas need to be accounted for.  Other than that, it's thin walled all the way and bone dry. 
 
The only machinery will be dehumidifiers, not CO2 scrubbers.  Life support will be oral/nasal masks exhausting externally.  At this point  [I reserve the right to change my mind] I will be keeping things simple.  O2 flow rates & monitors, CO2 scrubbing, Baralyme, etc. do not appeal to me.   Right now I'm viewing my boat as more of a vehicle than a life support pod.
 
Am I correct in assuming you will enter from the top somehow in order to stay dry, as opposed to entering from swimming in thru the bottom like some ambient subs require.
 
The cockpit will open via canopy like an aircraft.  If it was a pontoon boat the canopy wiould merely slide on rails.  Freeboard dictates that, in my Typhoon sub anyway, the canopy open at the top much like a hatch.
 
I saw your pics at the link you provided. I saw the bow and hull shape and stern shape. What kind of sail, bubble, or upper superstructure will it have?
 
An aircraft style, for example, a Chipmunk or fighter jet.  I may just make it a simple curve much like the windshields seen on catamaran hydrofoil boats (racing).
 
The IMAX Experience is paramount in my sub.  I want the feeling of being THERE, surrounded by water, waves and fishies.  Small portholes [a] do not permit this experience  [b] make diagnosing an entrapment almost impossible.  My thoughts are that the bubble canopy allows the underwater world to be felt, not just seen through a TV screen.  If small portholes deny the viewer, then
the technology is getting in the way.  The instrument should be incidental, not the goal [unless you're an engineer].
 
Needless to say, any design is mission specific.  Deep dives require a different set of parameters than the "IMAX Experience".  Portholes are specifically called for as canopies would be prohibitive both in cost and design evaluation.

Hi, Bill, et al . . .
 
In my continued search for meaning in life, I have decided to use the Russian Typhoon as the defacto choice for my first boat.  Why?
 
Mainly because the majority of the hull allows for simple curves that can be derived using sheet material.  Fast and easy to build.  Exceptions, of course, are the bow cone and parts of the stern and canopy support structure.  These will have to be faired accordingly.
 
If you take a look at the Typhoon pics I submitted to the list back in 2000, you'll see what I mean:   http://www.psubs.org/pic/typhoon.html
 
This design also allows me to cruise long distances and it avoids having to have surface support.  Our waters are surrounded by boats (Strait of Georgia, B.C., Canada - the Left Coast).  VHF radio, cell phones and EPIRBS will all summon help quickly.  If I'll be going far from shore (transiting) I'll wear my Viking (dry) suit.  If I'm staying close to shore - like sailing over to my local latte provider by the water's edge - I'll just wear my tux  ;-)

I would like to know more about your typhoon dry ambient boat. Do you have pics online anywhere?  Why is it called a "Typhoon" after a
 
Soviet class of sub? Is it's hull shape styled after the Russian boat?
 
Bill.

I'm still dedicated to building my Typhoon dry ambient boat.
