The Thulin K was a Swedish naval fighter aircraft in the 1910s. It was operated by both the Swedish and Dutch armed forces.
Development
Dr. Enoch Thulin, of AB Thulinverken, designed the Thulin K in December 1916. It was a shoulder-wing monoplane of wooden construction employing wing warping for lateral control, later ailerons. Powered by a 90 hp Thulin A Gnôme derived rotary engine, it could be configured as a single seat or tandem seat aircraft.[1]
Operational history
After initial flights in early 1917, the Swedish Army purchased two of the single seat K versions. However, it was more successful as an export plane; the Royal Netherlands Navy bought twelve K single seaters and three two seaters between 1917 and 1918. Both types were delivered without armament but the Dutch Navy fitted theirs with machine guns firing through the propeller arc and also experimented with 20 mm Madson cannons.[1]
