CFS1 Junkers Ju-F13
Chilean Air Force - Fuerza Aerea de Chile
The Junkers F.13 was the world's first all-metal transport aircraft, built in Germany at the end of World War I. It was an advanced cantilever-wing monoplane, with enclosed accommodation for four passengers. Over 300 were sold. It was in production for 13 years and in commercial service almost 20.
The F.13 was a very advanced aircraft when built, an aerodynamically clean all-metal low-wing cantilever (without external bracing) monoplane. Even later in the 1920s, it and other Junkers types were unusual as unbraced monoplanes in a biplane age, with only Fokker's designs of comparable modernity. It was the world's first all-metal passenger aircraft and Junkers' first commercial aircraft.
Like all Junkers designs, from the 1918 J 7 to the 1932 Ju 46, some 35 models, it used an aluminium alloy (duralumin) structure entirely covered with Junkers' characteristic corrugated and stressed duralumin skin. Internally, the wing was built up on nine circular cross-section duralumin spars with transverse bracing. All control surfaces were horn balanced.
Behind the single engine was a semi-enclosed cockpit for the crew, roofed but without side glazing. There was an enclosed and heated cabin for four passengers with windows and doors in the fuselage sides. Passenger seats were fitted with seat belts, unusual for the time. The F.13 used a fixed conventional split landing gear with a rear skid, though some variants landed on floats or on skis.
Junkers set up its own airline - Junkers Luftverkehr AG in 1921 - to encourage the acquisition of the F.13 by German airlines which was flying 60 of them by 1923. They also established a branch of this airline in Iran. Other marketing techniques were used, providing F.13s on cheap leases and free loans, with such effect that some 16 operators across Europe were flying them. When Junkers-Luftverkehr merged with Lufthansa in 1926, 9.5 million miles had been flown by them. Lufthansa itself bought 55 aircraft and in 1928 were using them on 43 domestic routes. Even in 1937, their F.13s were flying over 50 flights per week on four routes. They were finally withdrawn in 1938.
Some F-13 were military users. The Colombian Air Force used the F.13 (and the related W.33, W.34 and K.43) as bombers in the Colombia-Peru War in 1932-3. The Republic of China flew F.13s converted into scout bombers until the January 28 Incident in 1932, when they were destroyed by the Japanese along with the Shanghai Aircraft Factory.
The Chilean Army Air Corps, (later Chilean Air force) operated one F-13 and one A-20, single engined, Junkers planes, between the years 1924 to 1926, mainly in bomber duties, transport, training, reconnaissance and liaison.
The Junkers F-13, was a first passenger plane in crossing the Andes mountain chain in 1925 (with four passenger), but few months after crashed in Antofagasta region, during a training raid to the desert north region, resulting destroyed but without casualties.
