Hermann Dorner (born May 27, 1882 in Wittenberg ; † February 6, 1963 in Hanover ) was one of the first German engine aircraft designers.

Life

He studied shipbuilding in Berlin and became a qualified engineer in 1909. In the summer of 1910 he obtained the pilot's license No. 18 of the German Aviation Association.

In 1907 he had started developing a glider with a motor attached to its nose. In September 1909 he was the only German to take part in the 1st International Flight Week in Johannisthal . He had registered for the competition with his self-designed monoplane and was the first to present a German powered aircraft at a major event. But he could only show a few short jumps with his monoplane. On July 11, 1910, he won the third Lanz Prize of the Skies with his T II monoplane, endowed with 3,000  marks, and in August he won another prize at the air show in Johannisthal.

With the money from the prizes, he opened his Dorner Flugzeug GmbH in 1910. After 1912, however, his financial possibilities were at an end and he went to the Adlershof aviation school as a flight instructor . In 1913 he went to the German Research Institute for Aviation (DVL), which had recently been founded, as technical director .

In mid-1914 he developed the DFW BI and B.II with Heinrich Oelerich at Deutsche Flugzeug-Werken (DFW) . At the end of 1915 he became chief designer of the giant aircraft department of the DFW in Lindenthal near Leipzig, from 1916 chief designer for the aircraft engine development of the Hanoverian Waggonfabrik (Hawa), aircraft construction department in Hanover-Linden, where he designed the Hanover CL types .

He was also professionally connected with Hans Grade .

After the First World War , he worked on an air-cooled diesel engine and founded Dorner Ölmotoren AG ( DÖMAG ) in 1923 to produce small cars with 10 hp diesel engines, which failed due to inflation. The diesel engine tested Kurt Neumann then 1927. Dorner worked in the motor industry, including in Detroit , where he at the company Packard instrumental in the development of the Packard DR-980 was involved. With this aviation diesel engine, the first diesel powered flight was achieved in 1928.

In 1954 he was awarded the Federal Cross of Merit, 1st class .
