History of the Motorenfabrik Oberursel

Brief overview

The Motorenfabrik, founded in 1892, and since 2000 a site of Rolls-Royce Deutschland, is considered as being the world’s oldest active aircraft engine factory. The site goes back to 1882 to a factory built for the manufacture of grain milling machines. At the time it was the first mechanical engineering factory in Oberursel.
The company grew with the production of the stationary engine "Gnom", developed at the beginning of the 20th century, to the second largest manufacturer of motor locomotives in Germany. The orbital engines, built in Oberursel during the First World War, were used to equip the first German fighter aircraft, the most famous of which was the Red Baron’s Fokker three-decker or triplane.

The period between the world wars saw the manufacture of Deutz engines in Oberursel. These engines were installed in farm tractors, which advanced the mechanization of German agriculture. In addition, work was undertaken from 1941 onwards on the development of large-scale aircraft engines.
After World War II, the factory became a victim of reparations and was dismantled. The U.S. Army used it as a repair depot for the next 11 years.
At the beginning of the 1960s aircraft engine construction with various license productions and in-house developments moved into the factory.

A new era begun in 1990 with the development of the BR 700 series jet engines for regional and business jets.

After transition into Rolls-Royce Deutschland, the plant developed into a centre of excellence for rotating engine components, especially for compressor drums, compressor wheels in BLISK design and turbine discs.
