Question vents on VIIC

[urfisch]

I am modding the game "Uboat" and i am researching for some modifications of the control room model. Now i am stuck at this design from the vents of the Main Ballast Tanks 1 and 5 at U-995.

Question: On older pics of the VIIC type you see there just one vent, the one on the left for MBT 1 or 5. So, can anyone help me explaining this? Was it a change in design or was it specific for the VIIC/41 type (U-995)? On which boats there was only one vent?


Thx a lot in advance ;)

Info is hard to come by, i already tried finding out this 5 chambers ballast thing and those 'Untertriebszellen' and failed gloriously. Try to find when home, weekend.

Ok it seems i have Hildesheimer or what was that word :hmmm:

:haha: Thanks Aktung, but i am still not sure whether i wrote (or copied ahem) quotable stuff :oops:

But those posts still do not explain which lever is for what.. the mentioned two turning wheels at the front bulkhead of the Zentrale are obviously not the levers mentioned for rapid flooding.

Someone with more patience than me might find what they're looking for in one of these plans: http://www.uboatarchive.net/U-570/U-570DesignBook.htm
