The rocke motor on the ground. Hermann Oberth standing near an air-cooled rocket motor. External view of a combustion chamber of light metal, for 25kg of thrust. A view of interior is superimposed on it. A cutaway model is held in man's hand. He shows paths of fuel flow to combustion chamber and exhaust port. Hermann Oberth with his hand on the the actual rocket engine, as they prepare to fuel it with ethyl alcohol and liquid oxygen, at the Berlin Rocket field, in April 1932. The fuel cylinders are seen and vapors rise as they fuel the motor.. Using his hand, Oberth traces the paths of the oxygen and alcohol into the motor body, and the combustion exhaust path. The team steps back as Oberth pours alcohol into one side of the motor. The team steps back quickly and climbs stairs up a hill overlooking the test stand, where several other people await them. At the control site, they close the ignition circuit to the motor. Fumes flow down and flames flare up, but the rocket sustains a controlled burn fairly well, in spite of occasional flareups, and creates sustained thrust measured by the apparatus surrounding the test stand.
