The Dornier Do K was a German commercial passenger and freight monoplane designed by Claudius Dornier and built by Dornier Flugzeugwerke.[1] Only three prototypes of different designs were built and the type was not a commercial success.[1]

Design and development

Do K1

The first Dornier Do K was the K1 which first flew on 7 May 1929.[1] The K1 was a conventional braced high-wing monoplane powered by a single nose-mounted 510 hp (380 kW) licence-built Bristol Jupiter VI radial engine and had a conventional landing gear with a tail skid.[1] The square section fuselage had an enclosed cockpit for two with a cabin behind for freight or eight passengers.[1] Test flights showed that performance was poor and the aircraft was re-designed.[1]

Do K2

The Do K2 flew in December 1929 with similar wings and fuselage but had a changed landing gear and four 240 hp (179 kW) Gnome-Rhone Titan radial engines.[1] The four engines were strut mounted on each side of the fuselage in tandem pairs, one in tractor configuration and the other as a pusher.[1] Although the aircraft had an increase in available power the performance was little improved on the K1.[1]

Do K3

The K3 was a complete rethink of the design, the braced wing was replaced with a cantilever wing of larger span.[1] The fuselage was changed to oval and stretched for two extra passengers and the tail skid was replaced with a tail wheel and the main units were enclosed in fairings.[1] The four engines were in the same tandem arrangement as the K2 but located lower on the fuselage and changed to 305 hp (227 kW) Walter Castor radial engines.[1] The performance was greatly improved but still provoked little interest and no others were built.[1]
