Martin Schrenk (born June 17, 1896 in Bubenorbis , today the municipality of Mainhardt ; † May 13, 1934 near Dünaburg (Daugavpils, Latvia)) was a German aerospace engineer, aircraft designer and university professor .

Life

Martin Schrenk took part in the First World War as a pilot , then studied at the Technical University of Stuttgart and became one of the first successful glider pilots (C test no. 9). He was a long-time close employee of Hanns Klemm , who worked for the Daimler-Motoren-Gesellschaft on Sindelfingen location was responsible for the aircraft construction. Together with Klemm, Schrenk developed and tested gliders and light aircraft , including the Daimler L15 , L17 and L20 models . With an L15, powered by a Harley-Davidson bicycle engine with 12.5 hp, Schrenk made the first overland flight of a light aircraft from Sindelfingen to Untertürkheim at the end of November 1923 , followed a month later by another flight - this time with Klemm as a passenger. On March 17, 1924, Martin Schrenk and Werner von Langsdorff flew 120 km with a two-hour flight time on the Sindelfingen – Bensheim route . In June 1925 Schrenk won the "German round flight for the BZ-Preis der Lüfte" on an L20 and received 15,000 RM for the 2nd Otto Lilienthal Prize of Group A and 5,000 RM for the Richthofen Prize.

When Daimler-Benz AG , formed in 1926 after the merger with Benz , turned away from aircraft construction, Martin Schrenk switched to the German Aviation Research Institute (DVL) in Berlin-Adlershof as a test engineer . With a thesis on profile resistance measurement in flight using the impulse method , he received his doctorate degree in 1927 at the Technical University of Berlin . PhD. He completed his habilitation in December 1929 and received a teaching position for aircraft construction at the TH Berlin as a research assistant to Wilhelm Hoff .

In the early 1930s he became a member of the Academic Aviation Group in Berlin and, together with Walter Stender and Gerald Klein, designed the AB4 light aircraft based on a tender from the German Aviation Association (DLV).

He was killed on a research trip started on May 13, 1934 in Bitterfeld together with the meteorologist Victor Masuch from the Altitude Radiation Observatory in Potsdam. The gas balloon Bartsch von Sigsfeld stranded driverless near Sebesch in the Russian Oblast of Pskov .
