Lohner C.I - 1916

The unarmed Lohner B.VII and its armed derivative the C.I were military reconnaissance aircraft produced in Austria-Hungary during World War I. They were the ultimate developments in a family of aircraft that had begun with the B.I prior to the outbreak of war, and were the first members of that family that proved suitable for front-line service during the conflict. Like their predecessors, the B.VII and C.I were conventional biplanes with characteristic swept-back wings.

The Lohner L was a reconnaissance flying boat produced in Austria-Hungary during World War I. It was a two-bay sesquiplane of typical configuration for the flying boats of the day, with its engine mounted pusher-wise on struts in the interplane gap. The pilot and observer sat side-by-side in an open cockpit, and both upper and lower sets of wings featured sweepback. The design was essentially more powerful version of the Lohner E, and proved to be highly influential. Apart from licenced production by UFAG, the L provided the basis for designs from other major manufacturers.

In Germany, Hansa-Brandenburg manufactured a modified version of it as their first flying boat, the FB, and in Italy, a captured example was used as a pattern aircraft by Macchi, who produced it as the L.1. In turn, the L.1 would provide the foundation for a large number of Macchi designs over the coming years.

The Lohner Series 111 aircraft company was an Austria-Hungarian prototype single seat biplane built in 1917 by Lohnerwerke GmbH. The fuselage was a laminated wood construction. The wing struts were an "I" requiring no wires tor structural stability. Power was provided by an Austro-Daimler engine generating 185 hp (138 kW) The design went through several changes during the development process. Three prototypes were built. The performance of the aircraft was not an improvement on existing models already in production. Lackluster flight results led to Flars not approving the D.I for production.
