History
The Lohner C.I was an armed version of the two-seat reconnaissance aircraft Lohner B.VII used by the Austro-Hungarian Empire in the First World War. The B.VII itself was a derivative (and improved form) of the pre-war B.I biplane series, from which the B.II, B.III, B.IV, B.V and B.VI types emerged.
The B.VII became the final form of the two-seat platform and entered service in August 1915.
While some B.VII models were once field-equipped with machine guns, the C.I was a dedicated armed variant from the outset and was produced at the Lohner and Ufag factories in about 40 examples. In contrast to the open-engine exterior of the previous B.VII production model, the C.I also received a bonnet.
Power is provided by a 160-horsepower Austro-Daimler inline liquid-cooled engine. Armament consists of an 8mm machine gun mounted on a flexible bracket in the rear cockpit (in the open cockpit, there are two side-by-side seats).
Externally, the C.I has rear arrow biplane wing assemblies, double cabins and parallel struts with proper routing. The wings are staggered, with the lower components located some distance behind the upper ones. The forward fuselage is dominated by a large engine and cooling system, the former driving a two-bladed wooden propeller. The cockpit is located forward amidships, while the fuselage tapers sharply to a conventional tail.
The tail has a vertical tail and sweeps the horizontal plane. The landing gear is conventional, with two large main wheels and a tail skid.
Like the B.VII, production of the C.I ended in 1917 - surpassed by more powerful and shooting examples.
