Hi Tscrivens,
I will try to full in some of the technical details for you, but again, it will be on the Type IXC submarines. Please reply to let me know if this will help you in any way so as not to waste my time.
RUDDERS
The rudders are of the balanced streamlined hollow spade type, with the interior space filled with wood. Each has a plane area of 3.111m sq. (33.4 sq.ft.) of which .779m sq (8.35 sq.ft.) is forward of the stock. They are located 975 mm (38.4") out from the centerline of the vessel, and 225 mm (8.85") in toward the center of the vessel from center of the propellers.
The rudders are suspended, the weight and thrust being carrried by the bearings in the rudders trunk and at the head of the stock. Stops are at 30 degrees port and starboard.
DIVING PLANS
The stern planes are located directly aft of the propellers in the horizontal plane with the center of the propeller shafts. The plane area of each plane is 2.56 sq.m. (27.4 sq. ft.) of which .82 sq. m. (8.76 sq.ft.) is forward of the stock. They are arranged to work from 30 degrees rise to 30 degrees dive and are normally secured ar 2 degrees dive. This is a change from previous practice, promulgated in 1943 to reduce the tendency of surfaced vessels to run under.
The bow planes are located 1500mm (4.92 ft.) above the bottom of the pressure hull, just forward of the forward end of the pressure hull at frame 126. The plane area of each plane is 2.84 sq.m. (30.3 sq.ft.) of which .94 sq.m. (10.1 sq.ft.) is forward of the stock. They are arranged to work from 25 degrees dive to 25 degrees rise, and are normally secured ar 7 degrees rise. This plane positioning also stems from the same directive referred to above. Plans that are available show a designed 5 degree zero setting.
