Arthur Rudolph - Initial Work On Rocket Engines

Initial Work On Rocket Engines

In August 1927 Rudolph accepted a job at Stock & Co. in Berlin. After a few months, he became a toolmaker at Fritz Werner. In 1928 he attended the Technical College of Berlin— now the Berlin Institute of Technology —graduating in 1930 with the equivalent of a Bachelor of Science degree in mechanical engineering. On May 1, 1930, Rudolph began working for the Heylandt Works in Berlin where he met rocketry pioneer Max Valier. Valier had use of the factory grounds for his experiments in rocketry and Rudolph became interested, working with Valier in his spare time along with Walter Riedel. Rudolph already had some interest in rocketry, having read Wege zur Raumschiffahrt (Ways to Spaceflight) by Hermann Oberth and having seen the film Woman in the Moon.

On May 27, an experimental engine exploded and killed Valier. Dr. Paulus Heylandt forbade further rocket research, but Rudolph continued secretly with Riedel and Alfons Pietsch. Rudolph then developed an improved and safer version of Valier's engine while Pietsch designed a rocket car. Dr. Heylandt conceded to back the project, and the "Heylandt Rocket Car" was born and was exhibited at Tempelhof Aerodrome. While it was a technical success, the fuel costs were greater than the admissions received and performances were discontinued. Rudolph joined the Nazi Party in 1931, then later the SA.

Rudolph first met Wernher von Braun when he visited a meeting of the Verein für Raumschiffahrt (VfR, the "Spaceflight Society"). In May 1932 Rudolph was laid off and looking for work when he encountered Pietsch. After forming a partnership Rudolph began design on a new engine, while Pietsch looked for a backer. Pietsch met with Walter Dornberger, who had been tasked by the German Ordnance Department to develop a rocket weapons system and had become interested in the VfR.

After demonstrating the new engine to Dornberger, Rudolph moved to the proving grounds at Kummersdorf along with Riedel, and began working under von Braun. Rudolph's engine was used in the Aggregate series of rockets. In December 1934, the von Braun team successfully launched two A-2 rockets from the island of Borkum. Static testing on the A-3 engines began in Kummersdorf in late 1936 and were observed by General Werner von Fritsch, the commander-in chief of the German Army High Command.

The Kummersdorf facilities were inadequate for continued operations, so the von Braun team was moved to Peenemünde in May 1937 where Rudolph was tasked with the building of the A-3 test stand. The Rudolphs lived in nearby Zinnowitz, where their daughter, Marianne Erika, was born on November 26, 1937. The A-3 series was plagued with guidance problems and never proved successful. In early 1938, Dornberger put Rudolph in charge of the design for the new production plant to be built at Peenemünde for the A-4 series, later renamed the V-2 (Vergeltungswaffe-Reprisal Weapon-2).
