April, 1931 in Germany. View of a closed sled resembling a small airplane fuselage, fitted with runners underneath and bundles of rockets on each side. It sits on a frozen lake. BR-1 is painted on its side. A man arrives and climbs into the cockpit. The rockets ignite and accelerate the plane somewhat erratically, as it moves along the lake surface.
Descriptions and diagrams of various model airplanes used in experiments with solid powder propulsion, in Germany starting in 1927. Diagram of a 'Storch' model airplane. Diagram of "Ente"(Duck) model airplane. An Opel full scale model "Ent" airplane being checked out on a launching rail at an airfield. Fritz von Opel makes adjustments at the rear of the airplane and, assisted by several other men, moves the airplane along the launch ramp and back again. On the side of the plane is written: "Sander AK-1." Photographers take pictures. The first manned test of an Opel "ent" airplane is undertaken by the Research Institute of the RhonRossitten-Gesellschaft (RRG) under the direction of Fritz Stamer. In the first three trials the airplane fails to rise and simply skids along the ground. However, on the 4th try, it successfully flies off the launch rail in an extended high speed flight, for three-quarters of a mile in just under one minute. The successful flight is then shown in slow motion from two different camera angles.
Successful test of the first German Post office mail rocket at Dummersee, Germany, on April 15,1931. It carries 180 pieces of mail (postcards). Reinhold Tiling is seen with his mechanic, Friedrich Kuhr, who holds the rocket, as Tiling inserts a cylinder containing compressed powder fuel. They then invert the rocket and Tiling affixes its nose cone. A post office official hands pieces of mail to Tiling, who places them into the rocket. They position the rocket on its launch stand and fire it. Uniformed Postal officials (and some military officers) watch the rocket as it rises smoothly after launch. Larger, better, and lighter metal (aluminum) are developed in 1931-32. Friedrich Kuhr standing next to a huge rocket with a wing span of 4 meters.
Serious work on rocket development in Germany. Engineer at work. A small rocket test. Sketches for high altitude rocket motor. Sketch and model of high altitude liquid fuel rocket like that envisioned by theorist Hermann Oberth. Rudolf Nebel and Werner von Braun, members of the Space Travel Club (Verein für Raumschiffahrt) in 1928. They carry rockets over their shoulders at the Raketenflugplatz (Rocket launch facility) used by the club in Berlin-Reinickendorf. Launch stand for the Oberth high altitude rocket. Man placing rocket on the stand. Picture of a rocket descending by parachute.
A Valier R6 and Valier-Heylandt car move using liquid fueled rockets in Germany. A liquid fueled model of rocket. A Valier R6 car with 'Rockstoss-Versuchs-Wagen' written on it. A man sits in it. People stand around him. Rocket boosters in the car. The man wears helmet. He drives the car on road. People stand on sides of road to watch him. A Valier-Heylandt car in fueled from a tank. The car moves on road. Picture of scientist Max Valier.
Vierstabers rocket standing on its four legs on Lindwerder Island in Lake Tegel, Berlin. Men gathered around as the rocket is being fueled. Fumes from condensation seen. The rocket is fired and rises a considerable distance in the air before falling into the lake. Sketches of the rocket. Heavy steam fumes rising where the rocket has fallen into the water, because the motor appears to be still burning. Two more sequences of rockets launching from the island and falling into the lake. Men in a motorboat retrieving a rocket from the water. Another test launch of a Vierstabers rocket from a boat in the Schwielowsee (lake) in Germany. A motor launch traveling out on the lake, with a Vierstaber rocket on its deck and flying the German national flag. The launch next to a larger boat in the lake. The rocket launches high in the sky and falls into the lake.
