Franz Lösel (born March 1, 1883 in Hochdobern , Bohemia , † 1951 in Moscow ) was an Austrian engineer and university professor .

Life

Born into a farming family, studied at the Swiss Federal Polytechnic in Zurich . Aurel Stodola's remark that the development of the steam turbine had ended, brought Lösel to turbine construction . As a graduate engineer he went to the First Machine Factory in Brno . As a senior engineer, in 1923 he developed a back pressure turbine with an unusually high efficiency of 80%. With almost a quarter less coal consumption, the “Brno Turbine” produced a significantly higher output than all other steam turbines built to date. The Technical University of Prague awarded him the in 1926Honorary doctorate .

Lösel's successes alarmed established turbine factories such as AEG , Siemens-Schuckertwerke , MAN , Germaniawerft and Stork Hengelo . They obtained building licenses for this type of construction from the First Brno . The use of more than a hundred turbine patents was assigned to Turbo NV Amsterdam , founded in 1924 .

Although Lösel had bought a manor in Czechoslovakia and also ran a cattle farm there, he went to Vienna in the 1930s . As full professor he did research at the Technical University of Vienna . During this time he came into contact with Corps Saxonia Vienna , which awarded him the Corpsschleife in 1934 .

For the Wehrmacht he tried until 1943 to design steam jet engines as drive units for aircraft. He also had steam turbines he had developed for trucks and passenger vehicles built and tested in the Floridsdorf locomotive factory and the Oser & Nuss & Vogel machine factory in Krems an der Donau . For mass production of his inventions reached because of the Wehrmacht's unconditional surrender no more.

In occupied post-war Austria, Lösel and an employee were taken to Moscow on August 3, 1945 by the Red Army in a courier plane . All that is known about his further fate is that he had to continue researching in the Soviet Union and is said to have received the Stalin Prize for his work in 1947 or 1948 . He died in Moscow in autumn 1951 at the age of 68.
