Hermann Behrbohm was significant in the design of Saab 35 Draken and Saab 37 Viggen. He made the calculations supporting Alexander Lippisch developing the Delta wing concept at the end of the war. He received the Swedish Aeronautical Society's Thulin Medal 1968 in silver for having promoted aviation technology with work.[2][3]
He made efforts in aviation technology in several countries during his life, due to the circumstances. Finally, as a pensioner, 1972 he moved to England with his British wife. His children stayed in Sweden.
He authored many articles in aerodynamic and mathematical specialist press available on libraries and the Internet.[4]
Behrbohm was a research assistant at the Georg-August-Universität Göttingen in 1933–1936 and wrote his doctoral dissertation on the algebra identity of the meromorphisms of an elliptical function body. The thesis was not approved for political reasons when the supervisor was Jewish and Nazi Germany took over.[5] In 1944 he was promoted doctor in mathematics and physics.
Behrbohm also had great difficulties in marrying his first wife because of the regulations in Nazi Germany. She had difficulties obtaining biological purity certificates (unknown father) and thus being able to marry him, which was possible only in 1940.
Herrman Behrbom was asked for as a mathematician in the aerospace industry where you need to do your theoretical calculations and then run tests to drive development projects forward.
Augsburg 1937-1944
He participated in work on high-speed trials with Messerschmitt Bf 109 with Lukas Schmid.[6]
At Messerschmitt in Augsburg, the main project during these years was otherwise the development of the jet aircraftMesserschmitt Me 262.
After the air raids on Augsburg the 25 February 1944, the development activities were moved into the underground facility of the Oberbayerische Forschungsanstalt in Oberammergau.[7] The family remains in Mering close to Augsburg.
From autumn 1944, he worked half-time for the Aviation Research Institute Vienna (LFW) [8] in Wiener Neustadt, where Alexander Lippisch had opened his own development office.
Until then, Lippisch had worked for Messerschmitt with the rocket plane Messerschmitt Me 163. He and Willy Messerschmitt disagreed about the design, in which Lippisch did not want the rear wing, drag and worse performance.
After the war ended in 1945, Hermann was an unemployed father of a family with 4 children in Mering near AugsburgAmerican zone of occupation. They had income from gifts from housed American officers, but he also worked a time in agriculture and forestry with nature payments for family food on the table.[9]
In the spring of 1946 he was recruited by BEE (French Aerodynamic Research and Development Institute, today a part of Deutsch-Französisches Forschungsinstitut Saint-Louis) with operations in Emmendingen and Weil am Rhein in French occupation zone in Germany.
After the formation of the Federal Republic of Germany 1949 and the end of occupation, the opportunities were greater to find scientifically interesting work abroad and Behrbohm received offers from France and other countries.
Saab
Hermann chose 1951 to start working on Saab moving to Linköping with his family who became naturalized Swedes.
The motives for choosing to work for Saab were the projects Saab 32 Lansen and Saab 35 Draken under Erik Bratt and Tore Gullstrand.[10] Being a specialist in aerodynamics is a narrow labor market with few employers in the world who have sufficient resources to create good results. Saab where they built up operations and Sweden's ambitions gave Hermann the opportunities.
Hermann remained at Saab until his retirement in 1972. During the years 1960–64 he was head of the Aerodynamics department, also participated in the projects Saab 37 Viggen and Saab 105 and published a large number of articles in aerodynamics.[11] He was esteemed and won the Swedish Aeronautical Society's Thulin Medal 1968 in silver.
Hermann Behrbohm and Bertil Dillner made significant efforts in the design of Saab 37 Viggen, and in particular the design and tests of the Canard-wing construction.[12]
After retirement, he moved with his second wife to her hometown in the south of England and lived there afterwards.
