Since visiting U-10 in Wilhelmshaven i was thinking of building a 1/72 model of the boat...  Now i got a 1/100 papermodel in my
hands and an idea of upscaling the drawings to 1/72.  It

HI Anakin,

Being a digital print guy, I checked those numbers (sorry) and tho the usual true A-series to next up A-series is 141% (140 in certain circumstances), you are right about 139% from 1:100 to 1:72 (138.8888). I would go to a copy shop that does plan printing, and for probably about US$3 to $5 you could have the plan enlarged onto one piece of paper, probably A1 or A0. Much nicer than sticking several A3s together!

As for the planes, I couldn't see anything from those pix. I wonder if the linkage is broken in the photo you've seen (or if a drawing, if the artist had no idea), because they do NOT work like airplane ailerons for roll, they strictly work for pitch and they have to work together. Now if you mean curl instead 9which now that i look at the pic again you must mean this), I would say one was put on upside down! I would think they would have to be flat, or if designed curved, curving the same way, or they would naturally act as ailerons and roll the sub! I'm just as confused.

Looks like it would be a good model, and not too terible to do. keep us posted.

That is reeeeally strange! I'm far from an expert, but I'd guess she would just roll over and corkscrew! (which would be an interesting ride!) I also don't see the advantage to even just a curved surface (even if oth matched). I hope someone knows something about this!

I can't see for sure from the pictures but it looks like it might be a single screw.  Could it be a method of counteracting torque?

Hi Pat.

You are correct... It is a single propelled! So that might be it...

I sure would like to know the answer confirmed for sure, it does seem veeeery strange

Since the boat was quite small (44 meters), could it be that the front hydroplanes was just because anti rotation? Like adjusted to the speed of the propeller... Type 206 has the same kind of hydroplanes...

Hello together,

the U 9 in the technique museum in Speyer shows both depth control planes outside the hull, to present them at the same time. In use they were however hidden in the hull. For an upward motion of the bow only the rudder at starboard was screwed out, for a movement downward only the rudder on portside was expanded. The strength of the rudder effect could be controlled by the angle of screwing out.

regards
Schorsch
