Richard Otto Roosen (born October 13, 1901 in Hamburg ; † March 2, 1980 in Kassel ) was a German mechanical engineer .

life and work

SAR class 25 with exhaust steam condensation in use.

After studying mechanical engineering at the TH Dresden and training as a locomotive heater , he worked as a designer for Henschel in Kassel from 1925 . In 1927 he was promoted to chief engineer and in 1929 became head of the study office at Henschel. He received his doctorate in 1936 on the subject of exhaust steam condensation through air cooling on vehicles.

As early as 1929, when Henschel took over the management of the study office, it was concerned with the development of steam locomotives with exhaust steam condensation, which were used in the more than 170 condensation locomotives of the class 52 built during the Second World War and the 90 other condensation locomotives built after the Second World War Class 25 of the South African Railways flowed. Furthermore, together with his colleague Dr. Ing. Ulrich Barske 1939-1941 for the German Reichsbahn a fast moving steam locomotive with Einzelachsantrieb about steam engines , the Series 10/19 .
