The Aviatik C.I was a World War I reconnaissance aircraft which first came into service in September 1915 . It was the successor to the Aviatik B.I and B.II models. The observer sat in front of the pilot in this model which limited the gunner's field of fire. However, the opportunity was presented for more aggressive aircrews to take an increased offensive approach in engaging enemy aircraft. The positions of the pilot and gunner were reversed in the C.Ia version. Later models, the C.II and C.III were produced in large numbers and had more powerful engines.
The Lloyd FJ 40.05 was a very unorthadox Austrian experimental fighter/reconnaisence biplane built in 1915. The design's faults were many and virtues were few. The aircraft never went beyond initial testing before development was halted.
The primary stumbling block to the evolution of an effective fighter aircraft was the inability to fire into the forward arc without losing a propeller. Until the machine gun synchronization was invented, various aircraft manufacturers tried of solutions including pusher engine configuration attaching metal plates to the propeller, firing sideways, mounting a machine gun on the upper wing to fire over the arc of the prop, etc. None of these stop-gap measures proved to be the optimal method to achieve the goal of creating a truly efficient fighter-craft.The Lloyd Company designers tried a radically different approach to solve the problem. In 1915 they designed a two seat aircraft designated FJ (Flugzeugjäger) and received the Austro Hungarian Air Force designation 40.05.
Their design was unusual to say the least. The over-sized nose section of the FJ.40.05 filled the entire space between both wings. Immediately behind the upper wing's trailing edge was the machine gunner's post with an excellent field of fire. However, this solution reduced the pilot's front view as he sat behind this portion of the plane. The plane first flew in January 1916 but was not accepted by the Air Force. During 1916 the Lloyd 40.05 was converted to a single seat fighter fitted with a 0.315 in (8 mm) Schwarzlose machine gun in a Type II VK gun pod which pilot's referred to as the "children's coffin"). The Austro-Hungarian Air Force (der Kaiserliche und Königliche Luftfahrtruppen - K.u.K. LFT) wasn't interested in this version either and it was never put into production.
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 B.VII appeared in August 1915 and finally provided a machine suitable for service use. These were used to conduct long-range reconnaissance missions over the Italian Front, as well as occasional bombing raids, carrying 80 kg (180 lb) of bombs internally. Many B.VIIs in operational service were equipped with machine guns on flexible mounts for the observer, and this led to the armed C.I version being produced at both the Lohner and Ufag factories.
Aside from its factory-installed armament, the C.I also sported a streamlined cowling around the engine, whereas the B-types had their cylinders exposed to the airstream. Notable missions carried out by these aircraft included the raid on the Porta Volta power station in Milan on 14 February 1916 (a 378 km/276 mi round trip for 12 B.VIIs) and Julius Arigi sinking an Italian steamer at Valona in a B.VII in 1916.
Production of all versions ceased in 1917, and all were withdrawn from service soon afterwards.
The Lloyd C.II and its derivatives, the C.III and C.IV were reconnaissance aircraft produced in Austria-Hungary during the First World War. They were based on the Lloyd company's pre-war C.I design, and like it, were conventional biplanes with swept-back wings.
After the outbreak of World War I, the original aircraft was refined somewhat by Lloyd designers Wizina and von Melczer, featuring a reduced wingspan and wing area but increased weight. An 0.315 in (8 mm) Schwarzlose machine gun was added on a semi-circular mount for an observer, giving the aircraft a means of self defence against enemy fighters.
Beginning in 1915, one hundred examples of this type were built - fifty by Lloyd at their plant in Aszód, and another fifty by WKF in Vienna.
The C.III was almost identical to the C.II except for the use of a 160 hp (120 kW) Austro-Daimler engine, which increased the top speed to 83 mph (133 km/h) The C.III was produced by both Lloyd and Wiener Karosserie und Flugzeugfabrik (WKF), with total production run amounted to between 50 to 60 aircraft.
