The Junkers J 7 on February 2, 1918 during a comparison flight in Berlin-Adlershof

The Junkers J 7 aircraft was a cantilever low- wing aircraft manufactured by the aircraft manufacturer Junkers & Co. in duralumin construction and designed as a single-seater fighter . The first flight took place on September 17, 1917 . It was unsatisfactory at first, and several modifications were made, including to the ailerons , the landing gear and the engine radiator.

history

After the factory tests in autumn 1917, the model aircraft was assessed during the first comparative flight of new fighter aircraft in Adlershof near Berlin. Despite its outstanding performance, this type was rejected by the test pilots , which was mainly due to its design as a tension-free monoplane . As a curiosity, Junkers' competitor, Anthony Fokker , was able to fly the J 7 on this comparison flight, but broke it on landing. Since the J 7 could no longer participate in further comparisons, Fokker received the order instead of Junkers.

The lightweight construction efforts of Junkers showed success here. It was a duralumin used / corrugated iron sheeting, resulting in a curb weight resulted kg of only 655th

On April 2, 1918 , the Idflieg was offered an improved version again, but the construction of another J 7 was then omitted.
