Drawing of Motor S.R.5, from April 24, 1934, with exits in the combustion chamber and nozzle only from cooling coils. Picture of the S.R.5 motor. Sänger's drawings for a self-demanding pumping head in single and double piston designs. Such a rocket motor, designed on May 13, 1934, to generate 100 Kg of thrust. Pictures of the S.R.5 rocket motor and test apparatus, with it firmly fastened to a steel plate to keep it from moving during the burn test. Closeup of the actual burn test in Professor Sänger's workshop, Vienna Austria.
German Professor Eugen Sänger conceived of a rocket-propelled airplane in 1934. View of his sketches and notes.View of a workshop, close to his home, where Sänger developed his ideas. It is a nondescript building with wooden exterior and "Deutsche Raketenflug-Werft, Vien1934" (German Rocketflight shipyard, Vienna,1934) scrawled on its door. Professor Sänger and an assistant are seen in doorway of the workshop. Interior views of machinery. Blueprint cross-section of Sängers first Rocket motor (the S.R.1) from 1932. Drawing of test facility arrangement from 1932. Drawing of the S.R.2 rocket motor from 1933, with high pressure liquid oxygen cooling. Drawing of testing apparatus and arrangement from 1933, including Bosch fuel injection pump.
Drawings and pictures of Professor Eugen Sänger's S.R.13 and 14 Rocket motors from September, 1934. He holds a motor in his hand and points out its features. Photograph of Austrian patent certificate number 144809 issued to Doctor Eugen Sänger in Vienna, effective September 15, 1935, for Rocket engine and method for its operation. Glimpse of illustrations in the document. Drawing of planned 500 Kg thrust rocket motor designed by Sänger Rocket Motors. Eugen Sänger's drawings for a rocket-propelled missile to hunt airplanes. Design of a rocket motor (the S.R.X), on June 10, 1934, with 1000 kg thrust for a tropospheric experimental aircraft. Image of a letter to Dr.Sänger, from the the Federal Ministry of National Defense, dated February 3, 1934, stating that his ideas were not practially realizable.
Rocket cooling investigations influenced rocketry pioneer, Professor Eugen Sänger's design for his rocket motor, S.R.3. View of his drawings and notes from 1934. Display of mechanical parts from the S.R.3. Items comprising test apparatus for the rocket motor, with various parts labeled. Mechanical Testing setup in Sänger's work shop and instrumentation, labeled in German, showing things such as motor thrust, pump pressure, liquid oxygen level, etc. The first burn test on March 15, 1934. Sänger stands in doorway of his workshop in Vienna, using a long pole to initiate the burn. Various views of flames emanating from the prototype rocket motor during the burn test. A revised sketch of the S.R.3 prototype rocket motor. Test of this version with flames barely visible due to complete combustion, during start-up and operation.
Drawings of Professor Eugen Sänger's S.R.8 Rocket motor from July 5, 1934. The actual motor set next to a milimeter scale. Chamber of SR8 with external cooling groove before and after welding. Various views of the S.R.8. on the test stand with instrumentation in place, inside Sänger's workshop, in Vienna, July 19, 1934. Closeups of the test firing of the S.R.8 rocket motor, showing consistent smooth controlled burning.
