For the UD-1 (project 50) German Steam driven U-Cruiser design you will want to get a copy of "The U-Boat, The evolution and technical history of German submarines" by Eberhard R�ssler. US Naval Institute Press 1989 , translated and printed in the US.
Used book search should turn one up.
I am looking at the discription of the project on page 75. Included is a layout drawing of the Turbines and boilers. 4 boilers built into the sides with the steam turbines in central compartments.
Work started in Feb 1918 when "War contract AA" was awared to KW Kiel for a U Cruiser of this type. In May work started in the mould-loft and work shops in great secrecy. But the keel was not layed down yet at the end of the war.
All Approx:
length overall 125m.
Max beam 10.5m.
draught 6m
displacement surfaced 3,800t
propulsion surfaced 4: 6,000 hp steam turbines, 2 450 hp diesel generators
propulsion submerged 2: 1,900 hp SSW electric motors
speed surfaced 25knots
speed submerged 9.5 knots
armament: six torpedo tubes [four submerged bow, two submerged stern]
three or four 15cm U-Boat guns
crew: 104
The hull was developed in accordance with Project 46a, but a greater length was envisaged [125m].
For more info consult the book, or private message me and I'll give you all that is printed about the project in the book.
Sorry I can't scan it.
