Kalinin K-5 ( Russian Калинин К-5 ) is a Soviet airliner . It was used in the 1930s by the Aeroflot forerunner Dobrolet and the German-Soviet airline Deruluft . There, together with the ANT-9, it replaced the previously dominant foreign, mainly German, aircraft types.
development
The designer Konstantin Alexejewitsch Kalinin began development work on the basis of the K-1 in 1926 . From her he took over the typical elliptical Kalinin wing made of wood in a shoulder -wing arrangement with a profile Göttingen 436 . The fuselage consisted of a tubular steel frame with a rectangular cross-section. In the bow area it was planked with duralumin and otherwise, like the wings, covered with fabric. It could accommodate up to ten passengers. The first flight of the prototype took place in April 1929. Due to a broken wing, it crashed during testing, whereupon the wing structure was revised and reinforced. Series production began in 1930 and ended in 1934 after the 260th machine. The K-5 was equipped with different drives, first with the Bristol Jupiter license engine M-15 (335 kW / 450 PS), from 1931 with the M-22 (355 kW / 480 PS) developed from it and finally the in- line engine M- 17F (544 kW / 730 PS), a license for the BMW VI .
The K-5 flew partly until 1940. A further development K-6 only existed as a prototype .
