The Scheibe "Zugvogel" is a glider in composite construction manufactured in the 1950s by the company Scheibe-Flugzeugbau in Dachau .

history

The migratory bird is a development of the series of migratory birds that Rudolf Kaiser designed at Scheibe-Flugzeugbau .

Versions

Migratory bird I

The first flight of the Zugvogel I took place in 1954. The tubular steel fuselage is clad with plywood in the front area in order to achieve a higher aerodynamic quality. The unrestricted wings with 16.0 m span have a laminar profile and are swept forward strongly in the prototype in order to remain on the safe side when tilting. The forward sweep was reduced on the following aircraft because the tilting behavior was within tolerable limits. The Zugvogel I has a nose coupling and a center of gravity coupling, within the Zugvogel IIIA series the nose coupling was dispensed with and only a center of gravity coupling is used, which is used for both aircraft towing and winch launch . 3 of the Zugvogel I were built, and 7 according to other sources.

According to the EASA data sheet, 3 pieces with the serial numbers 1002-1004 were built.

Migratory bird II

The Zugvogel II flew for the first time in October 1956. The wings are no longer swept and are built with a box spar. The tubular steel fuselage has become a little shorter. Piano hinges are no longer used for the ailerons, but rather single bearings, which reduce manual effort. Only 2 of the Zugvogel II were built.

Migratory bird III, IIIA and IIIB

The Zugvogel III flew for the first time in April 1957. The span is now 17.0 m. The migratory bird initially has a runner, grinding spur and a two-wheeled landing gear that can be released, a bow and a center of gravity coupling arranged next to the runner. The Zugvogel IIIA has a fixed central wheel size 4.00-4. Within the series Zugvogel IIIA (from serial number 1052) the nose coupling and the runner are dispensed with and only a center-of-gravity coupling is used, which is used for aircraft towing and winch launching . A lower trunk is used for the Zugvogel IIIB. 86 of the Zugvogel III, IIIA and IIIB were built.
