The Junkers K 16 was a business jet made by the German manufacturer Junkers & Co. in the early 1920s. In addition to the pilot, the high- wing aircraft could accommodate two more people. K stands for "cabin aircraft". In-house it was also referred to as the J 16.


The K 16 was created in 1921 based on knowledge gained with the Junkers J 15 . It was developed by Junkers chief engineer Otto Reuter . The first flight took place on March 3, 1921. After the victorious powers of the First World War issued a total aircraft construction ban on May 11 of that year, the machine was then dismantled into its individual parts in order to avoid confiscation and brought to the Netherlands. There the further flight took place. In 1923 it was first exhibited in public at the Gothenburg Air Exhibition.

The aircraft was mainly used on sightseeing flights or as a company aircraft, but it was also used as a sports machine .

Designed as a cantilever high-wing aircraft, it largely took over the design of its predecessor J 15. However, the open cockpit was relocated in front of the passenger cabin in order to give the pilot a better view and to protect him from the turbulence of the engine's exhaust gas. The fuselage of the machine had only a small ground clearance, so that one could step into the cabin. The wingspan, which was 11 meters in the prototype, was increased to 12.80 meters in the series version.

The machine was initially equipped with a 45 kW radial engine Sh 4 from Siemens & Halske and thus complied with the regulations of the post-war construction restrictions imposed by the Versailles Treaty . With a cruising speed of around 125 km / h, however, the aircraft was comparatively slow. After the presentation in Gothenburg in 1923, the Siemens & Halske Sh 5 with 63 kW (K 16a) and later the Bristol Lucifer with 74 kW (K 16ce) were installed, which enabled a speed gain of 10 km / h to be achieved. A machine exported to Czechoslovakia with the registration number L-BACA (K 16bo) received a 96 kW Walter motor , the speed increased to 150 km / h. The K 16bi variant from 1925 was equipped with a 92 kW Siemens Sh 12 .
