Johannes Winkler and the first test of a liquid fuel rocket, in Europe
Views of Johannes Winkler's first prototype (HW1-A) liquid fuel rocket. Preparations in the field for testing the HW1A. Views of Winkler and associates setting up and fueling the prototype. Photographs of The first test of a liquid fuel rocket (Winkler's HW1-A)in Europe, on February 21, 1931, in Dessau, Germany. Sketches of his model HW1-C. Photograph of Winkler sitting next to the HW1-c, on a bench in the laboratory. A so-called Shear diagram pertaining to stresses experienced by the HW1-C rocket.
Dr. Johannes Winkler and his designs for Liquid fueled rockets.
German Rocket pioneer Johannes Winkler and his liquid fueled HW2 rocket. Diagrammatic drawing of the HW2 liquid fueled rocket, that Winkler designed based on his prior experience with the HW1c. He considered liquid fuel the key to achieving stratopheric heights. Dr. Winkler in his laboratory with rocket models. He is seen outdoors, setting the HW2 on a launch stand. Views of the HW2 ready for launching. View of data recording devices built by Dr. Winkler. Cold fumes seen from liquid oxygen. View inside laboratory of HW2 with its data instrumentation. Original Shear diagrams for the HW1c and HW2 rockets. The HW2 in its casing and a cutaway drawing of it. View of quick opening valve for liquid methane and liquid oxygen.
German Doctor Johannes Winkler and his HW2 liquid fueled rocket
Dr. Johannes Winkler, rocket pioneer. Laboratory workers pose next to outer casing of HW2 liquid fueled rocket. Dr. Winkler making adjustment on the HW2. View of HW2 standing on its tail on the ground beside the launch control building. Assistant holds slate warning of explosions, and Winkler and his assistants toast the rocket's completion by drinking beer from bottles. Camera pans vertically over the rocket. Winkler opens a flush door in the rocket and places something inside. Winkler seen describing features of the rocket for the camera, while his staff stands nearby.
Johannes Winkler and test of liquid fuel HW-2 rocket on beach near Danzig
Dr.Johannes Winkler, rocket pioneer and his HW2 liquid fueled rocket. Winkler and his staff standing in front of the Hw2 rocket, conversing, at the Konigsberg fairgrounds in 1932. Dr. Winkler explaining his rocket to interested visitors at the fairgrounds. Closeup of Dr. Winkler as he speaks. View of the launch site where spectators are gathered at the Vistula Spit near Danzig (Gdansk) Poland, on the Baltic Sea. Winkler and his assistant on the sand beach,fueling the rocket with liquid methane. The rocket team checks meteorlogical conditions. Winkler being interviewed by a reporter. while Winkler continues the interview, his assistant, on a ladder, begins fueling the rocket with liquid oxygen. Winkler inspects it after fueling. The staff places the nose cone over the rocket. Technician in white coat checks ignition, as German naval officers and other officers and officials stand nearby. Winkler opens flush door in rocket and places something inside. German still camera men and a cinematographer, wearing army helmets, prepare to record the event. Another photographer takes refuge in a trench on the sands. At launch, the rocket lurches upward, and falls to the ground, where it burns. Winkler's staff throw sand on it to put out the fire. Winkler and staff examining the wreckage to determine the reason for the explosion (rather than smooth burning of fuel). Dr.Winkler making notes. Winkler and assistant examining fuel containers and ignition wires.
Work of Rudolf Nebel and Hermann Oberth to achieve controlled burning of Liquid fuel for rockets
July 7, 1930, Oberth and Nebel jointly achieved conrtolled burn with their cone nozzle for a rocket. Diagram of their cone nozzle and view of it being placed in a test frame outdoors. A burn diagram showing steady output. Diagram of the small (mini-rocket) named "Mirak." Views of the test stand set up in Bernstadt, Germany, with instrumentation. Rudolf Nebel standing on a small ladder looking at the rocket. The Mirak in flight. A Mirak explosion. Several buildings comprising Nebel's rocket facilities. Diagram of liquid-fueled rocket motor. Rudolf Nebel and Hermann Oberth at the test stand with their apparatus and views of it in snowy field. Test stand for the burner test in Berlin, 1931 and an explosion that occurred. View of the device with hole blown in it
Hermann Oberth conducts burn test of rocket engine fueled with ethyl alcohol and liquid oxygen
Hermann Oberth performing a burn test on an Oxygen-alcohol fueled "Repulsor" rocket motor. Diagram of the 1 liter "Repulsor"motor and view of the actual motor, with electrodes atop it. 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.
