Submarine Project

I nearly fell off my chair when I first saw this thread, I have been watching it with amusement. When the forum started to talk about 40 foot opening doors I thought Oh this is ridiculous no one will answer further to this, well I was wrong. It is only now that I wanted to have my say as Mr Kc started to back off, I Presume he has obtained sufficient information to proceed on his own.
The smartest thing some one said was how will you be able to inform people that you are just a friendly submarine. I think this is a valid point, I mean there are no friendly submarines, all are military, ( ok some will site one that isnt) but most are very threatening. You expect to just cruise into New york Harbour with it. What with the threat of terrorism how far do you think you will get. Or just sail by the USS Nimitz? Jeesus they went nuts when I went past it on a jet Ski, and that was years ago. Have you got a death wish? It seems a very expensive way to go.
Im sure Pearl Harbour would give you a warm welcome.

 

Ha.....Ha...... That right, I was wondering about friendly destroyer class ship saying friendly hello to surposely friendly techno build advance friendly Family crusing Submarine?

He can build it but would find the world lonest place to cruise. Dont think Asia would ask for your VISA permit before dropping the barrel.

Good Luck

Ultraistic? I'm just wondering what advancement of Man Kind can be made by a Expedition Sub? I'd understand a Research Sub or a Cargo Sub. Submarines are the most Fuel Efficient Vessel when thay are traveling underwater I believe, But there wouldn't be much for the occupants to see. 100 meters operating depth is close to the limits of most the words Naval Submarines Do you really need it? From a design point of view What is the Design Brief 40mtr-50mtr LOA Beam ? Powered by ? Able to load of ( cargo 13mtrs long width ? weight ? ). Its intended Use and Sphere of operation.

 

KC, why don't you take a page out of Bill G's book and give your excess spoils away to a decent cause instead of wasting them on such an ill conceived fantasy? Lot more satisfaction than being depth charged by your own country.
Or, being sunk by an amorous whaleshark trying to mount your heliport!
Explain that to your Missus.(In your underwater tomb) Your face would be as red as your neck.

oh! I forgot,you are french.
French-American.......from Kansas..?

You will be doing yourself,your family and the world, a great service by building your submarine.

 

submarine yacht did a project

Hello DREW,

I did a submarine yacht project in 1996 i found that building and maintainance cost of a small submarine yacht are very similar to a small sailing yacht - see project at www.tolimared.com/submarine
US subs is going for a ultra luxury segment that must be very small.
Let me hear your thoughts...

 

i built a personal submarine yacht 9m 20 tons see: www.tolimared.com/submarine
just a few thoughts...submarine is like airplanes you can do it extremly expensive design team or just take a couple of alu tubes and nylon fabrics and fly. I insist a submarine must not be more expensive than a yacht of similar size - all depends on the concept...

 

Haha. This thread is fun!

 

Storing a helicopter in a submarine - but without using a 40foot opening for the helicopter hanger.

I have just read how the the Japanese during ww2 developed 'aircraft carier submarines' - the Sen Toku I-400 class. (There was also the earlier B1 type - carrying a seaplane).

Note the photos attached below - the aircraft hanger is attached to the top of the submarine - perhaps part of the sail/tower. The hanger-door is a cone perhaps 5 meters wide.

I cant see why this wouldnt work for a helicopter. You could even use a folding landing-pad. Fold the blades of the 'chopper' up, perhaps lower the landing frame and roll it into the hanger. Or use one of those tiny one seater or two seaters made in Tirol? with the Rotax motors?

Anyway the hanger-door as a cone makes more sense.

It is amazing that nothing is new in this world. The French had 2 seaplanes in their sub 'Surcouf' (spelling?), the english had HMS M2, Italy had one. But the Japanese really made the deal work.

 

Here you have a weird one, built at my hometown, Vigo, in 1898:
http://www.funditesa.com/esp/historia2.htm (Pages in spanish)
It was built and tested, mercifully not at war! (The explosion of the charge at the end of the perch, supposed to sink an enemy's ship, would have destroyed the submarine as well!)

 

Commersial sub.

Yellow sub marine..No helicopter hangar..no aeroplane..no guns. Thailand and some other tourist resort .If you would like to experience a yellow submarine tour..welcome !

submarine mega yacht - a different aproach

Hi i really would like to work on a project like this...

I understand the question of viewports - they are expensive - you have to change them after 10000 dive cycles they are hardly to integrate in a streamline shape. just get a couple of camaras and a wall of plasma screens and you will see a lot more around your sub as you would see trough viewports. Carsten made this point clear latley in psubs.org.

A couple of months ago i discussed with carsten (merlinsub) the idea of a sub made of a series of concrete spheres as pressure hull and outer streamline hull without viewports this boat could go VERY deep - carry a big ROV for salvatage - and you could cut one of the spheres in half without weakening the hull opening it on surface as a helicopter hangar...

My proyect : Concrete Submarine Yachts


you could build that kind of sub in floating status similar to bridge foundations of golf of corinth...no shipyard needed...

You could build it VERY big... see platform leg below ...




Iimage1
Statoil's massive concrete based Heidrun platform. The legs of this platform reach over 100m down.
down into the sea.

Image2
Inside the concrete leg of a drilling platform. Those engineers at the moment of the photo are tecnically "dived at 150 m protected from water pressure by a submarine concrete hull" of collosal dimension that stands vertically instead of horizontally.
- just flip that platformleg (in your mind) 90 degrees and add a propeller - you have a giant submarine. This is not a new horizon tecnically speaking - it is just to see things from a slightly different angle.

Image3
Grande Dixence, on the river Dixence in Switzerland, concrete dam. It was built between 1953 and 1961 to a height of 285 m (935 ft). Concrete at the foot of this dam holds a watercolumn of 285m - equivalent of 285m dive depth in a submarine.

Image4
HIBERNIA CANADA, drilling platfrom 105.5m deep diving concrete submarine hull...

Image5
Golf of Corinth Greece, the legs of this bridge go 70m down to the ocean floor. They where built at sea in floating status and do rest on ocean floor with very little force to enable the bridge to move in case of earthquakes - so this bridge is founded on 70m deep dived submarine concrete hulls.

Image6
Seikan Tunnel - This train emerges from the depth of 240 m below the sea of japan where ist was protected during his passage by nothing else than a submarine concrete hull - horizontally in this case...

Not a bad idea at all... I seem to recall that back when Boeing was all high on Sonic Cruiser hype, they were talking about replacing the cockpit windows with a set of big flatscreens, that the pilots could switch between different cameras. Makes a lot of sense there, you can't fly a fast plane like that VFR anyways even if you wanted to. And it would have let them streamline the nose a lot better, without the Concorde's mechanically nasty hinge mechanism. The same principles should apply to a sub, I would think.

 

replace viewports with camera

On a big sub you also might get better view in infrared or by this new development of acoustic camara that gives you a image made from sound reflections. You also might need to send out a ROV to cut your propeller free which is not in sight of any viewport. It is like starship enterprise - put it on main screen...in near future you also might opt to navigate with a simulated landscape - based on boat position and geo-databases like in a flight simulator.
You also might do a couple of hundreds of detail shots with the ROV on a shipwrack and then mount the photos together to a clear overview on your screen just as if poor visibility would not exist - we have seen that from Titanic... A well mounted camara system gives you a picture you could never get trough a viewport - especially on a big sub.

Kindest Regards

Hi,
very exciting thread indeed..

1/ About the japanese&french airplane/heli silos at the top of the submarine get higher res pictures here:

Yes similarly, very interesting project doucumenting the outside hydrodynamic body and the bare presure hull is here
(this is basically a first demo project-version of the US Submarines Discovery model):

3/ "It is like starship enterprise - put it on main screen...in near future you also might opt to navigate with a simulated landscape - based on boat position and geo-databases like in a flight simulator."

Exactly, you can utilize hybrid-synthetic picture which is combination of computer data, here in case of submarine preferably by some public available GIS-NASA world ocean relief data with the live camera/gauges/diagnostics pasted over the image..

Some examples and tutorials how to do it here:
