Another torpedo thread?

Libor,
I am glad you

Libor,
I am glad you are enjoying this thread. And thank you for posting those pictures. What a great way to start talking about working doors for the torpedoe tubes.

In Libor's picture the outer torpedo door has to open about 20 degrees. It seems relatively easy to implement this.

Kevin's Oscar and my Sierra (all the modern cigar shaped hulls) will need to rotate the doors a full 90deg to get them out of the way. And the mechanism will be in a pretty confined location. I suppose we could attempt to slide them away too but that's just not the way they work....

Has anyone done something like this?

well you could make it

well you could make it a shutter style door with an alignment springs and fly by wire style control system. that would take less space then a hinged system. Depends on how authentic you want to go chris?

[cstranc]

How authentic... I want it

How authentic... I want it to work, and be in the water in time for the SubRegatta at Carmel (this year). Other things are negotiable.

Even funtioning is negotiable. I am thinking of just going with open tubes for now...

Your going to the regatta

Your going to the regatta huh? Well hopefully I will meet you there. I doubt my other akula will be ready in time though because i am deploying shortly.

Have you thought aabout cutting the top of the cone off and attaching it to the bottom so you wont have to worry about removing it with the top.
For what im thinking of for a shutter style torpedo door wouldnt be to difficult but open tube is always easier.

I thought of another intresting idea. Do it like a ball valve. Take sphere and drill a hole through it then just attatch a servo and tada. its fast and reliable. NO complicated linkages or anything. Just have to make sure the alignment is right or the torp will bind while passing through. We uise them all over the boat and they work great!

Ohh a second though. you could even run a presurizzed launching tube if you used the ball as a valve like they are intended. Then you could get a free launch out of the boat and then the remaining fuel in the torp. Just a though. Its how we launch the real thing "kinda"

Nuke,
The ball valve

Nuke,
The ball valve idea is truly exceptional. I don't thing I could make one, but it get's top marks for a neat solution to a tricky problem.

Of course now as I wonder through the world I will be looking for something I could convert into that ball valve.

Hope to see you in Carmel.

If you don't mind me asking, what are you deploying on / in?

LOL dont you look at

LOL dont you look at my avatar. USS RHode Island SSBN 740. Read my article in the next SC Report

I Dont think the simple ball assembly would be to difficult. Tell you what ill try and build one underway and well see what happens.

Ohh that's what that funny

Ohh that's what that funny picture means.



Is that you?

Have to say I'm more than a little jealous. I would die just to see one of these submarines sail past. You get to be onboard. Of course the view from inside is probably quite limited.

I am looking forward to your article.

Yeah thre arent any windows

Yeah thre arent any windows in the engine room so, itis rare to get up in the sail and just look around. It is my favorite place on the boat though. I love the open ocean.

NOW go make your boat!

Here is a drawing of

Here is a drawing of an idea for a torpedo door opener and launcher.



The picture looks better here.http://www.subcommittee.com/SubComm/...oor%20mech.JPG

Rotating the shaft moves the door out of the line of fire and a pin pushes the torpedo off its mounting.

Ohh dear. Now that's two

Ohh dear. Now that's two great ideas.

I was in Home Depot the other day and picked up a plastic ball valve as suggested by Nuke. 1/2" innter diameter on the ball would be about perfect. The outside diameter would not really match the hull though.

With Scott's idea I could shape the exit door. The are of the hull where the exit doors are located is more vertical so it would not rotate out of the way so easily. Still if I just accept the torpedo doors being recessed into the hull 1/16" I think it would work very well.

Thank you.

you could always re contour

you could always re contour the ball

Hi Kevinmc
Can you tell me

Hi Kevinmc
Can you tell me how you manage soldering fins in place at the Master piece ??
The first one OK but when I'm going to solder the second or third the others @#&*%@+ desoldered.
Thanks very much.

[KevinMC]

Hi Tony,

The simple answer is

Hi Tony,

The simple answer is I don't solder my fins in place on the master. Since the final parts will be cast from some other material, there is nothing gained by going to the trouble of soldering the fins in place so I CA them, then go back and add fillets using spot putty.

If you have a need to solder your fins in place, you'll need to make a jig that holds all of them in place so they can all be soldered in a single operation.

Hi Tony,
What I did

Hi Tony,
What I did to be able to solder the fins is to first drill two holes completely through the tail cone body. Now you have 4 holes at 90 degrees apart. In the narrow end of the tail, a small hole to hold a drill bit.
Next, slide a piece of square tubing, the size of the narrowest part, over the drill bit.
In the 4 holes, insert a piece of steel wire, solder will not stick to steel easily.
Using alligator clips, take your fin material and clip it to the wire so that the fin material exerts a small pressure on the wire when you clip the other end of the fin material to the square tubing.
You will be using one clip for two fins for the square tubing so a total of 6 clips.
After you have soldered the fins, you can trim/shape them as necessary.
Hope all this helps.

Best, Ed

Kevin and Ed,
Thanks very much

Kevin and Ed,
Thanks very much both of you. I'll try both ways and lets you know what happen. Later on I'll post photos of my subs due I am the only sub modeller in Greece. I've got five babes in my hand, four of them operational.
