In this diagram the V2 Turbo-pump is shown in a cutaway presentation and rotated 90 degrees counter clockwise. The B stoff (fuel) pump is nearest the viewer – the over-speed device can be seen on the B stoff pump’s case end-plate. The low pressure inlet ports our shown to the left, and high-pressure outlet ports are on the right. The steam distribution manifold can be seen at the furthest point from the viewer – the steam inlet pipe flange can also be seen. The feed pipe from the steam generator attaches to thus flange.

This mpe* drawing from 1945 shows the individual steam buckets or blades (labeled A and C) mounted to the rim of the rotor disk. As well as the fixed (i.e. stationary) stater blade B, positioned such that blades A & C can pass either side of it. The steam expansion is well shown by the increasing surface area of the blades from A to C, and growing larger, from left where the high pressure super heated steam enters the turbine, to right where it exits the blade pathway and passes in to the exhaust outlet. The lower graphic shows the way the super-heated high pressure steam is passed from the initial A blade and deflected by the reversed B stator blade for its energy to to be harvested for a second time by the C rotor blade. * mpe is the secret three letter armament code for Karlshagen, Werk Nord (North Works).

This HVP technical drawing from October 1940, shows a proposal from the Oddesse company – the full title of this company is KLEIN SCHANZLIN ODDESSE GmbH. Klein, Schanzlin & Becker A.G. (waffenamt code: ebb) took over Oddessa in 1929 and the company became formally known as KLEIN SCHANZLIN-ODDESSE GmbH (code ebc) in 1939. (NB: The company name has nothing to do with a similar sounding place name Odessa. The Oddesse trading name was formed from the partnership of English engineer Oddie, and German businessman Hesse.). The dual centrifugal turbo-pump shown in the drawing is a variant of a high pressure fire-fighting pump manufactured by Oddesse. Note the off-center outflow ports – not also that the outlet flanges are still level at this stage. Note also the incorrect spelling of the company name in the details panel lower right.

Another HVP technical drawing from later in October 1940, shows further data from the KLEIN SCHANZLIN ODDESSE (ebc) company A4-V2 turbo-pump project. See previous image for company details. The dual centrifugal turbo-pump shown in the drawing is a variant of a high pressure fire-fighting pump manufactured by Oddesse. Note the off-center outlet ports. Note also the corrected spelling of the company name in the details panel lower right (see previous Oddesse image) and the small note below the top table that indicates that the pumps are from Oddesse (ODD) and the turbine from a company indicated as SSW.
