Junkers K 37
The Junkers S 36 was a continuous tape as a low-wing experimental aircraft of the German manufacturer Junkers from the 1920s. It was the first twin-engined model of the manufacturer and could carry three people. Following this example, the bombers Junkers K 37 Mitsubishi Ki -1 originated and Mitsubishi Ki -2.
History
In the S 36, it was a cantilever low-wing monoplane of all-metal construction. The aircraft was equipped with two Gnôme - Rhone radial engines of 440 kW each. The first flight took place on 5 September 1927. Originally used as a combat aircraft S 36 ( WerkNr. 3200) was planned.
Unlike the other Junker aircraft was tentatively used smooth metal sheet in the prototype of the S 36 for the planking of wing leading edge and upper wing surface. The also clad with smooth metal nose cone was subsequently glazing, while an opening for a camera was attached to the hull bottom.
After the end of the experiments, this aircraft was sold as S- AABL to the Junkers branch AB Flygindustri in Limhamn, Sweden and served as a prototype for its' Junkers K 37 This machine was armed and was equipped as bombers. Their good performance at high altitudes made them inaccessible to the fighters of 1927. Towards the end of 1927 the machine for aerial purposes was converted, then flew the only S 36 as D -1252, then as D- AMIX, again in Dessau. The S 36 was officially approved in 1928 as the first twin-engined machine for aerobatics.
The Japanese forces were at this advanced aircraft interest, and on this basis developed the Mitsubishi Ki -1 and Ki -2.
