Overall view of the forward end of the torpedo afterbody.

Picture 1 of 2.

Looking at the turbine, I was struck by how much it reminded me of a rocket engine turbopump (such as this V-2 missile's turbopump). The combustion flask on the other side of the turbine bulkhead took the place of the V-2's steam generator, directing the steam (and, in the case of the torpedo, hot combustion gasses as well) to the turbine wheels.

Unlike a V-2 turbopump, where the turbines directly power the pump, the torpedo's turbines power a gearbox which turn shafts to drive the propellers.

The torpedo's two turbines spin in opposite directions, to cancel out any gyroscopic effect the rotation of the turbines would have on the torpedo.

The copper-colored tank in the foreground is an oil tank (there's another, barely visible, in the background).
