Pappenburg gauge and cryptic markings
Ok, one thing has me stumped: after our visit to U-995, we are trying to understand what the markings are on the Pappenburg gauge, and why there are two of these gauges. Is one for the each scope? What do the marks mean? thanks!
Big images, easy to see the detail http://www.wolfpackgame.com/img/research/pappen1.jpg http://www.wolfpackgame.com/img/research/pappen2.jpg http://www.wolfpackgame.com/img/research/pappen3.jpg http://www.wolfpackgame.com/img/research/pappen4.jpg Also,why would the spacing be so uneven? On the left gauge, there's a big difference between 5 and 6 and then 6 and 7....?

The right one seems to show the same for other parts of the boat. For example, on the right side there's a conning tower (brücke) mark at -9,7m. So, to get the boat submerged fully, the water level inside the tube would have to raise above that mark. No idea what the markings on the left side mean. |

It seems that it shows markings of the hight of several parts of the boat.
Kiel = Keel Bug = Bow Heck = Stern Brücke = Bridge (the lookout platform of the conning tower in this case IIRC) My best guess is that this was used to go decks awash or just submerge certain parts of the sub...I could be wrong though. However I don't get it that on the right it's one tube with two very different scales...

Brückes awash??!!
^Just guessing wildly here: but the U 995 was schnorkel equipped; one of the marking on the Pappenburg guage is "Brücke" In German: 'bridge' but also in Norwegian (she surrendered at Tronheim Norway and was taken over as the "Kaura' in use for 15 years.)...Brucke in Norwegian is also 'exhaust'...related to the schnorkel??? Since the notation has an umlout I would guess German notation for decks awash to enable the late radar array to remain above water in the perilous end days of WWII; a precise notation at -6.6 to -7 meters if not also the schorkel ( "he who schnorkels well-lives") in the stress related atmosphere of a late kreigsmarine zentrelle, a harried planesman would have an instant memory refresher for a 'correct micro depth adjustments. FuMO 65 Hohentwiel U1 Type F431 C1 for type VII Uboats was for aircraft detection. No need to stay fully surfaced awaiting some Liberator PB4Y's centimetric leigh-lighted doom??!!

While searching for more info on the papenberg, I came across this site.
There's a user by the name of 'Tore' who served onboard KMN Kaura (U-995), KMN Kya (U-926) and KMN Kinn (U-1202). Might be a good idea to ask him, if he knows more about the papenberg. He also gave this warning about the U-995: Quote:
Anyways, here's a thread where he answers questions about the boats: http://models.rokket.biz/index.php?topic=921.0 |

If I had known it's called Papenberg and not Pappenburg I might have had more success in finding something.
But we've been on the right track. The german Wikipedia article says that it was indeed used for submerging just parts of the boat. It was quicker to react to pressure changes than the normal depth gauges and was therefore better for the fine adjustments needed to keep the boat exactly at the required depth. The guys at uboat.net were a bit more precise than us though:http://uboat.net/forums/read.php?3,9...2541#msg-92541

Ah too late but the information in Uboatnet is what you looked for.
And b.t.w. everyone knows that it's the "Papenberg"

It's all about the UMLAUT; From a dutch 'Snuiver' 2 a Norwegian 'snortvalve'

I've got it:
The left gauge is for precise depth when shallow. It shows the depth to keel under the command room, and the hull outline gives a reference to determine which parts of the superstructure are submerged. This should be familiar from SH3. The nonlinear scale is due to water pressure acting against a reference air mass; as the volume of air is reduced by pressure, additional pressure has less effect. The right gauge is for *angle* of the boat, with the middle scale probably showing degrees. The vertical orientation is confusing for people used to spirit-levels and other types of horizontal "bubble" gauge. The extra scales to left and right are correction factors to determine the depth of the foredeck and aft keel (when angled up), and the afterdeck and fore keel (when angled down), relative to the keel depth shown on the left gauge.
