Junkers A 35 was a two-seater cantilever monoplane, used for postal, training and military purposes. The aircraft was designed in the 1920s by Junkers in Germany and manufactured at Dessau and by AB Flygindustri in Limhamn, Sweden and conversions from A 20's were made in Fili, Russia.
Design and development
The A 35 was a development of a series of Junkers aircraft from 1918, starting with the J10/J11, the A 20, A 25, A 32, and finally the A 35. It was originally intended as a two-seat multi-purpose fighter aircraft and made its first flight in 1926. Due to the post-war restrictions, Hugo Junkers and the Soviet Government signed a contract about the setup of an aircraft facility at Fili in Russia in December 1922.
In 1926, the first Junkers L5 engines were mounted on the Junkers A 20s. With some further tail modifications the new aircraft was designated as A 35. A total of 24 aircraft were originally built as A 35s. A number of A 20s and A 25s were also modified with the Junkers L5 engine. The A 35 was also available with a BMW IV engine.
