The Wien was a single-seat glider that was built in 1929 as a one-off for Robert Kronfeld at the Rhön-Rossitten-Gesellschaft (RRG).
history
In order to be successful in the “performance competition” at the 1929 Rhön competition , a new aircraft was developed from the professor on behalf of Robert Kronfeld . Based on a design by Alexander Lippisch , Hans Jacobs, with the support of Emil Pohorille, constructed the glider named after Kronfeld's hometown, Vienna , in late autumn 1928 in the flight technology department of the RRG . The aircraft was built by Kegel-Flugzeugbau Kassel; the first flight took place on February 26, 1929 from Kahlenberg near Vienna.
construction
The shoulder wing, each braced with a V-handle, had a two-part wing . This had the same wing area as the Professor , but three meters more wingspan (19.10 m) and thus a higher aspect ratio ; the normal tail was taken over almost unchanged. The cross-section of the trunk was elliptical; the cockpit was tailored to Kronfeld.
use
On May 15, 1929, Kronfeld set a world record in the Teutoburg Forest with a flight distance of 102.2 kilometers. At the Rhön competition in August 1929, two further world records followed with 142.4 and 149.4 km and the increase in the altitude record to 2281 and later 2589 meters. In May 1930, the longest flight in England to date followed with around 80 km . At the Rhön in 1930 he set his own record with flights of 150.3 and 164.8 km. On June 20, 1931, the Wien was the first glider to cross the English Channel . Sold to France in 1932, the aircraft lost its track in 1938.
