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).
