Igo Etrich (1908)

Ignaz "Igo" Etrich (born December 25, 1879 in Ober Altstadt , Austria-Hungary , † February 4, 1967 in Salzburg ) was an Austrian pilot and aircraft designer.

Life

Etrich, whose father Ignaz Etrich owned spinning mills in Oberaltstadt, attended secondary school and commercial school in Leipzig . But he was mainly interested in the birds' ability to fly. He built an experimental laboratory with his father. After Otto Lilienthal's death , his father bought several gliders that showed him the way. In 1903 he developed the first flying wing based on the model of the flying seeds of Zanonia macrocarpa and got the patent for it in 1905. Franz Xaver Wels was his partner and later a test pilot.

In 1906 a man-carrying flying wing flew for the first time with the Etrich Wels glider.

Etrich 1 , 1907

In 1907 Etrich went to Vienna , where he built his first motorized aircraft , the Etrich 1 , on the grounds of the rotunda in Vienna's Prater in 1907 , with an engine with a power of 24 hp attached to the rear. Only afterwards did he improve the aircraft (nicknamed Praterspatz ) with a front propeller and an additional conventional tail unit. With Franz Wels, later with Karl Illner , he developed the monoplane further - Wels separated from him and devoted himself to the double-decker .

Etrich II in the Technical Museum Vienna

After the airfield was founded in Wiener Neustadt in 1909, he built two hangars there and carried out further flight tests. He improved the Etrich 1 with a more powerful engine. The rudder was adjusted with the feet, for surface twisting ( ailerons were only generally used later) and the elevator , Etrich introduced control by means of a steering wheel from an automobile : the forerunner of today's control horn . In 1910 the maiden flight of the Etrich Taube , Etrich II , took place.

Etrich's Taube was patented in Austria , and due to the good flight performance, Etrich was able to conclude a contract with Edmund Rumpler , according to which he was granted the right, in return for a license fee, to replicate the aircraft in Germany under the name Etrich-Rumpler-Taube . However, the German patent office was unable to grant a patent for the Etrich Taube , so that anyone could copy the aircraft free of charge. Professor Friedrich Ahlborn wrote about the stability of flying machines from 1897 , who had recognized the shape of the Zanonia seed with its ideal flight characteristics and the importance of the shape for future aircraft construction. Rumpler then made no more payments to Etrich and, contrary to the contract, brought out the same aircraft under the name Rumpler-Taube .

Etrich then founded the Etrich-Fliegerwerke in Liebau / Silesia (now Lubawka / Poland ) in 1912 and designed the first passenger aircraft with a fully enclosed passenger cabin, the aerial limousine . Ernst Heinkel headed the design office .

Later he founded the Brandenburgische Flugzeugwerke and took his very talented designer Ernst Heinkel with him from Liebau. After the First World War Etrich went to Trutnov back and designed in 1929 another plane: The sports pigeon , a 40 PS strong sports plane .

During the first test flights it turned out that this aircraft flew faster than the military aircraft of Czechoslovakia at the time . The Czech authorities accused Etrich of having built his aircraft for smuggling activities and confiscated it.

Igo Etrich then gave up his aviation efforts and devoted himself entirely to his textile machinery business .

In 1945 Etrich was expropriated and expelled from Czechoslovakia.

Later Etrich turned to spiritualism and, at an advanced age, also published a small brochure about his spiritualistic worldview ( confession and spiritual legacy of the aviation pioneer Dr. Ing.hc Igo Etrich ).

His grave of honor is located at the Salzburg municipal cemetery .

The Etrich II is exhibited in the Technical Museum in Vienna .

The sport pigeon is exhibited today in the Technical Museum in Prague .

Political commitment

Etrich was a member of the Sudeten German Party from 1935 to 1939 and officially joined the NSDAP in May 1939 . In his application for membership in the NSDAP, Etrich emphasized his readiness "after the victory of the German arms, to help solve the major technical problems that the German people will face as a result of the space gained in the East ."

Honors

In 1944, the Vienna University of Technology awarded Etrich an honorary doctorate . In 1955 he received the Cross of Merit (Steckkreuz) of the Federal Republic of Germany. In 1959 Igo Etrich was awarded the Karl Renner Prize .

In 1971, in Vienna- Simmering (11th district), Etrichstrasse was named after the aircraft designer. Streets in Salzburg, Graz, Linz, Innsbruck and Berlin-Adlershof also bear his name.
