Obviously that’s the rocket motor. The bottom, or outlet, is shown toward the left of the photo. It’s the damaged part. You can just see a few of the burner cups on the upper side toward the right of the photo. That’s where the fuels were mixed and combustion began. The tubes attached near the bottom carried the alcohol fuel-it was pumped into an annular space between the inner and outer shells of the rocket motor. This kept the metal cool enough to avoid burning under the heat of combustion and also pre-heated the alcohol before it was introduced in the burner cups. The alcohol was pre-cooled by passing through the cryogenic oxygen tank on its way to the motor. Near the end of the war, fields and fields of potatoes were converted into alcohol for V2 fuel, depriving citizens of an important food source. These things were essentially powered by potato vodka.
