experimental high altitude aircraft, F/F 2nd October 1931, 1 built
cantilever monoplane, corrugated Duralumin, pressured cockpit
The developement of the Junkers Ju 49 was initiated by the Deutsche Versuchsanstalt fur Luftfahrt (DVL) in 1929.
The only purpose of this aircraft design were the experimental high altitude flights. Therefore a special cabin section
was developed, which was capable for flights up to 14 km altitude. This cockpit section was completly seperated from
the other parts of the aircraft. Just a few very small windows were included in the cockpit section. For ground views a
optical telescope was used. To get enough forward force in high altitudes, a large propeller area was necessary as movable
air screws were not available at the end of the twenties. The Ju49 propeller had a diameter of 5,60 meters, which required
an adequate high undercarriage. The required engine power was ensured by the Junkers L88
engine, which was already used at the G38.
On Oct. 2nd 1931 the Ju49 (c/n 3701) was first flown by Hoppe. During 1932
a lot of handicaps of the Ju49 design were reduced and in 1933 the aircraft was handed over to the DVL, which achieved
altitudes of 9300m in 1933 and of 12500m in 1935. The single built Ju49 crashed on 1936.
