The Lohner 10.15, also known as Schichtpreis Eindecker Type 1914, Lohner A 23, Gnome-Etrich and by its c/n AD 489 (AD 498?), was a monoplane racing aircraft designed and built in late 1913 for the 1914 Schichtpreis race. Requisitioned at the start of World War One by the Luftschifferabteilung (LA), the sole 10.15 remained active as a trainer until at least November 1917.

Design and development

Construction of the 10.15 began in October 1913 as the last Lohner aircraft built as a Taube with the distinctive wing plan-form and warping wing roll control. Construction of the 10.15 was conventional with fabric-covered wooden structure and shoulder-mounted wings wire-braced to king-posts above and below the fuselage. The undercarriage consisted of a sprung wooden tail-skid and sprung main-wheels on a split axle attached to the fuselage and king-posts. [1]

Power was supplied by an 80 hp (60 kW) Gnome Lambda 7-cylinder rotary engine. [1]

Gnome Lambda rotary piston aircraft engine

The Gnome 7 Lambda was a French designed, seven-cylinder, air-cooled rotary aero engine that was produced under license in Britain and Germany. Powering several World War I era aircraft types it was claimed to produce 80 horsepower (60 kW) from its capacity of 12 litres although recorded figures are lower.

Operational history

AD 489 did not compete in the 1914 Scichtpreis race as the pilot, Viktor Wittmann elected to fly the Pfeilflieger AD 553 (Lohner 10.16) which was also enterred in his name. The aircraft was also enterred in to the Third International Flugmeeting in June 1914 (competition number 23), but did not garner any prizes. [1]

After being requisitioned at the start of World War One by the Luftschifferabteilung (LA), the sole 10.15 remained active as a trainer until at least November 1917, serving with Flek 1, 6 and 8. [1]

The Sopwith Tabloid and Sopwith Schneider were British biplanes, originally designed as sports aircraft and later adapted for military use. They were among the first types to be built by the Sopwith Aviation Company. The "Tabloid", so named because of its small size, caused a sensation when it made its first public appearance.

Fokker M.5

The Fokker M.5 was an unarmed single-seat monoplane aircraft designed and built by Anthony Fokker in 1913. It served as a light reconnaissance aircraft with the German army at the outbreak of World War I and was the basis for the first successful fighter aircraft in German service, the Fokker E.I.

Aviatik (Berg) D.I aircraft

The Aviatik (Berg) D.I, was a single-engine, single-seater biplane fighter that was developed and manufactured by the Austro-Hungarian branch of German aircraft company Aviatik. It was also known as Berg D.I or the Berg Fighter, because it was designed by Dipl. Ing. Julius von Berg, and to distinguish it from the D.I fighter built by the parent Aviatik firm in Germany.

Farman HF.20 reconnaissance aircraft family

The Farman HF.20 and its derivatives were a family of reconnaissance aircraft produced in France shortly before and during the First World War. It was a refined version of the Farman MF.11 "Shorthorn" that did away with the type's distinctive landing skids, and incorporated design features from Henri Farman's designs. It entered service with the French, Belgian and Serbian armies in 1913, and with the British RFC and RNAS shortly after the outbreak of war. The type was also licence-built in the UK by Airco and Grahame-White.

The Sopwith Two-Seat Scout was a 1910s British biplane Anti-Zeppelin scout biplane designed and built for the Admiralty by the Sopwith Aviation Company. It was nicknamed the Spinning Jenny due to a tendency to enter a spin.

Knoller C.II

The Knoller C.II was a reconnaissance aircraft built in Austria-Hungary during World War I for use by the Austro-Hungarian army. It was a conventional biplane design with staggered wings, and seated the pilot and observer in tandem in an open cockpit. Like Knoller's preceding C.I design, the upper wing was swept back, but not as far as it had been on the earlier aircraft. The structure was wooden throughout, with the wings skinned in fabric and the fuselage in plywood. The interplane struts were made of steel and arranged in a warren truss configuration.

Intended to be as fast as possible, it recorded a speed of 135 mph (217 km/h), which made it the fastest aircraft in the world in 1914, but no production followed and it was soon written off in a crash.
