Junkers A 50
The Junkers A 50 was a single-engine, two-seat all-metal light aircraft whose maiden flight took place on 13 February 1929. The built at Junkers & Co. design was designed by Hermann Pohlmann (1894-1991) and used the typical Junkers aircraft alloy Wellblechbeplankung. The machine has been variously referred to as A 50 "Junior".
Type history
After the first flight in February 1929 a total of five prototypes were built to test various engines over the course of the year. Junkers hoped for a production number of 5000 specimens of as a kind of folk imaginary plane A 50, but could be produced during the construction period a total of only 69, as the plane was quite expensive at about 16,000 Reichsmarks; Moreover, there was from October 1929 global economic crisis. Thus, of the machines built only 50 sold. These aircraft were among others, Finland, Switzerland, Japan, Portugal, South Africa, United Kingdom, Brazil and Australia. Some machines have also been used by airlines.
No passenger was on board, was the vacant space will be closed with a cover. From the A 50CE the wings for a flyover to the fuselage could be folded.
Attempts
The A 50 is a series of experimental modifications were tested. Thus, a single wheel landing gear was tested, the centrally owned a wheel under the fuselage. Under the wings there were resilient runners.
A machine has been converted to a high-wing aircraft. This machine tests were made with variable angle of attack of the wing.
Records
The type A 50 presented a series of FAI world records. In the design with floats and the 59 kW payable Armstrong Siddeley Genet engine were obtained:
Marga Etzdorf flew in 1930 as the first woman with her yellow Junkers Junior alone from Berlin to Tokyo.
Variants
Basic model with a 59 kW Armstrong Siddeley Genet engine. The wings are still without dihedral.
Wings with dihedral, 59 -kW motor - Walter
Wings with dihedral, but Armstrong Siddeley Genet 59 kW
Wings with dihedral; equipped with 63 -kW Armstrong Siddeley Genet II engine for export with the Genet Major -I with 74 kW. wings beiklappbar
Wings with dihedral, with a 65 -kW Siemens - Halske Sh - & - 13 engine. wings beiklappbar
Wings with dihedral, 63 kW Armstrong Siddeley Genet II engine, in addition, some modifications to the airframe, wings beiklappbar
Aircraft received
An example is in the Deutsches Museum in Munich, one located in the departure hall of the airport Helsinki - Vantaa.
A third aircraft was exported in the 1930s to Australia and flew there intermittently until the 1990s. In early 2009 this A was 50 brought to Germany in the art "Hugo Junkers " in Dessau, where they loan from a private collector waits for the restoration.
