Heinrich Hertel

from Wikipedia, the free encyclopedia

Heinrich Hertel (born November 13, 1901 in Düsseldorf , † December 5, 1982 in Berlin ) was a German aerospace engineer. He was a doctor of engineering and professor of aeronautical engineering and military economics leader .

Life

From 1921 to 1925 Hertel studied civil engineering at the TH Munich and at the TH Berlin . After completing his studies, he worked at the German Aviation Research Institute in Berlin-Adlershof. In 1930 he received his doctorate from the TH Berlin. From 1933 he worked in the research and development department of Ernst Heinkel Flugzeugwerke Rostock . He joined the NSDAP on May 1, 1937 (No. 5.084.115). From 1938 he was honorary professor at the University of Rostock and from 1941 at the TH Braunschweig . In 1939 he moved to Junkers Flugzeug- und Motorenwerke as head of development and later became a member of the board.

At Junkers he worked on the investigations that led to the discovery of the area rule together with Otto Frenzl and Werner Hempel . He was also involved in the development of the swept wing and significantly in the development of the He 100 and Ju 287 aircraft . For the Ju 86 he developed the first full view altitude cabin that allowed to fly up to an altitude of 14 kilometers, and he was also involved in the development of the Ju 252 and the Ju 86R, equipped with a pressurized cabin and cylinder fuselage. During his time at Junkers, the Ju 90 was developed as a freight and transport version , the Ju 290 as a four-engine and Ju 390 as a six-engine version and went into series production.

In addition, he took the initiative in the development of the first jet propulsion aircraft ( He 178 ), the first liquid rocket aircraft ( He 176 ) and the design of a 100-seat Atlantic aircraft as well as the development of wide-body jet aircraft.

After the end of the war he worked in France on the development of jet planes and vertical take-off technology . In 1955, the Technical University of Berlin appointed Hertel to the chair for aircraft construction. At the TU, he continued to research aircraft designs and continued his work on vertical take-off technology, which he had begun in France, until 1970.

Hertel became a pioneer of bionics in aviation , because he examined the body shape of various fish species and developed a hull shape with less air resistance than conventional hull shapes. In contrast to the standard and therefore inexpensive fuselage sections that have been customary up to now, however, differently shaped segments would have been necessary, similar to a shark body , which is why Hertel's proposals were not incorporated into aircraft construction. Hertel received from the RWTH Aachen the honorary doctorate , furthermore, he was appointed honorary member of the German Society of Aerospace appointed and an honorary citizen of the Space Center Huntsville.

He was married and had a daughter and three sons. After 1949 he turned away from aircraft construction when the focus was on the construction of fighter planes in France and worked in the mining of coal and ore until 1955. In 1960 he turned against arms research at universities and sat down publicly on the occasion of his honorary doctorate in Aachen on April 16, 1970, dealt with his work before 1945.
