VIIC/41 - Schematices drawing

[NZSnowman]

Hi Simon

Have you seen any measurement for the length of the torpedo tube within U-boat? I got a measurement of 3020 mm does this look right? It matches very near to the total length of 7552 mm.

Unfortunately I have never met exact measurement of the part of the tube inside and outside the boat.
I suppose, that for that moment you have to estimate it from the drawings.

Thanks, the measurement of 3020 mm will be either one of the following

Maciek, I read that the late war Type VIIC/41 lost the function of using mines. If, so that would happened to say the opening in the bow cap casting for the compressed air pipe for the mine bolt actuator? Would they just wield up the opening or do you think they redesign the bow cap for the Type VIIC/41

Hi Simon,

Thought you would like the image

I reckon there is a piece on the deck that might be triangular (or something like a triangle). The block at the end of the jumping wire connects around this triangular piece, with either a rivet or a nut/bolt holding the block onto the triangle.  That's what it looks to me.

Cheers,

Dougie

Hi Dougie

I am easy to please

I think a triangular make 100% more sense than my idea! I will check my drawing and see of there any framing under the deck in the vicinity of the fix point.

Two things I just notice, one a white strip across the deck - training boat?

And a wield line near the stern of the casting, I have not see this before, will need to check this.

Hi Simon

To my understanding the inlet is only on the port side of the boat, is that right Maciek

That's right.

I have some original German measurement for this inlet for the pressure hull. I will
measure this out on the outside of the boat and see how it matches on the inside.

Where have you got this measurement?
Is it from the link you gave below, or some else source?
Please give the info, if this match.

Maciek, have you seen the information that Dani from http://www.u-historia.com/ got from Joachim Scherneck-Czech,

Yes, I think, that they would only weld up the openings for the compressed air pipe
for mine bolt actuator as well as for mine discharge lines.
I don't think that redesigning the bow was necessery.

Here I have got next few parts of flood installation.

I think that blue arrow points the blank place, where the flow meter was installed.

Hi Maciek

Would not the Black Arrow be the flow meter? It found on both side, and its look like the lid flip open to display a counter at the top.

Also how good is your German (or anyone) I just can not like out all the letters on this name plate. Also below the name plate you can see a flow arrow which you usually always found a flow meters.

Great photo.
It is clearly visible, the plate says:

Hi Maciek

► Do you have any views of the piping (Red Arrow) to the left of this photograph? I am trying to follow the pipe out of the flow meter.

► Also from below, the valve to the sea: Originally I was thinking this was only an inlet valve, but now I think it an inlet and out valve, is this correct?




► I think I have located the two main drain valves (f) from the drainage system.

Unfortunately I do not have any views, moreover, viewing below pictures, I think that this piping is led under the deck/casing and it is hard to see.

Yes, the valve can take water from the sea as well as can be used to blow water from compensating tanks.

I think I have located the two main drain valves (f) from the drainage system.

I'm sure you identified the valves correctly.

Where does this photo come from?
Is this from uboataces.com U-995 DVD?

I am sure I have located the two pipes I am looking for from photographs. One is directly under the personal lockers and another pipe runs along the pressure hull near the floor. I am sure I know with pipe belong to which system, base on the size of the pipes, but I was hoping to double check this.

Well, in such case I can't wait to see the drawings
