The Bücker Bü 180 Student was a civilian German sport and beginner's training aircraft made by the aircraft manufacturer Bücker Flugzeugbau .
history
The aircraft was developed in 1937 as an economical sports and beginner training aircraft. The first flight took place in November 1937. Up to the outbreak of war, a total of 23 units had been produced in Rangsdorf . A small number were exported. All of the Bücker Bü 180s listed in the German Reich at the time of the Second World War - as well as numerous other civilian sport aircraft - had to be destroyed in the course of the "type adjustment". There are only two copies left (as of 2020).
In 1938, this aircraft was used to fly a Trans-Africa flight of 25,000 km and set a speed record of 1,000 km at an average speed of 171.95 km / h.
construction
The aircraft was developed as a cantilever low wing in a composite construction . With the Bü 180, Bücker tested a construction method that was new to him. Instead of the proven, fabric-covered tubular steel frame of the Jungmann and Bestmann , it had a fabric-covered front part of the fuselage made from a welded tubular steel framework, the top of which was clad with sheet metal, and a plywood shell stern. The fabric-covered wings were made in the usual wooden construction. The leading edge of the wing had a sweep of 8 °, while the trailing edge was almost straight. A normal chassis was used as the chassis. The spring-loaded and oil-dampened star wheel could either be coupled to the rudder or rotate freely. The engine was initially powered by a French four-cylinder in-line engine Train-4T with 40 HP (29 kW), later with a Zündapp-9-092 in - line engine with 50 HP (37 kW). Later (B version) the 60 hp (44 kW) Czech Walter Mikron II engine was added. A single prototype (planned C version) also contained the 80 hp (59 kW) M-700 engine. The crew sat one behind the other in open seats. A cabin cover was also possible.

Preserved copies
The Bü 180 B-1 with the serial number 2106 was built in 1938 and exported to Switzerland. First it was based in Locarno , then in Sisseln and finally in Eiken . From 1971 they were exhibited in the Bücker studio in Göppingen . Later she went to the German Museum of Technology in Berlin .
The second surviving copy rolled off the production line in 1939 with work number 2115 and was also delivered to Switzerland. There it was initially approved as HB-UTO. Between 1945 and 1947 she even flew with swimmers at the Dornier company in Altenrhein on Lake Constance. After several other positions in Switzerland, she came to Germany in 1969, where the student was briefly registered as D-EFTO. Then it was first preserved and stored. Restoration began shortly before the turn of the millennium. The Bü 180, which Eichelsdörfer restored to airworthy condition, was sold to the Quax-Flieger Oldtimer Club in Paderborn at the beginning of 2016 , where it was registered under the registration D-EUTO. It was baptized on March 5, 2016 in the name of the first owner "Franz Herrmann" and ceremoniously presented to the public. The plane has been flying again since August 5, 2020.
