Lloyd FJ 40.05 - 1915

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.

Aviatik-Berg (Aviatik) Dr.I sn-30.24- 1917

The Aviatik 30.24 (this designation indicating that it was the 24th experimental aircraft produced by O-UF Aviatik) single-seat fighter triplane designed by von Berg in May 1917. The Aviatik 30.24 employed a similar structure to that of the D.I and the fuselage was very similar. Based on a contract with Aviatik for four experimental fighter planes powered by 185/200 hp Daimler engines in Sept 1917.

Flight testing of 30.24 on Oct 1917, the 185 hp powered 30.24 had inferior performance compared with a similar engined Aviatik D.I. The 200 hp Daimler also shows little improvement. The Triplane was referred to FLEK (FLiegerErsatzKompanie) 6 in Wiener Neustadt, where a variety of experimental radiators were installed to improve the pilots forward view on Aviatik fighters. 30.24 was accepted by LFT inspectors in Sep 1918. The remaining three prototypes (designations unknown), completed but disassembled, were accepted at the end of Oct 1918. The 30.24 was offered for sale to the Czechoslovakian government in April 1920.

Hansa-Brandenburg L.16 - 1917

The Hansa-Brandenburg L.16 was a single-seat equi-span fighter, developed by Hansa-Brandenburg for the Austro-Hungarian K.u.k. Luftfahrttruppen. It had a distinctive triplane configuration with aerofoil-section I-type interplane bracing struts. The L.16 was powered by a 185 hp (138 kW) Austro-Daimler six-cylinder water-cooled engine. The proposed armament for the L.16 consisted of two synchronized Schwarzlose machine guns. Various coolant radiator arrangements were evaluated on the single prototype built. Evaluation flights proved the fighter did not perform well enough to warrant series production. The development of this design was abandoned.

Lloyd Triplane

Lloyd Triplane - 1917
Lloyd Triplane - 1917

The Austro-Hungarians built many bizzare aircraft, and the Lloyd 40.15 was no exception. The Lloyd 40.15 triplane fighter prototype was a rather ungainly aircraft with a lot of unique features. It had fully cantilevered wings, probably of mixed veneer and fabric construction. It appears that the wings were originally designed to be all veneered with tipperons. Then the wing construction was changed to a veneer/fabric construction. On the middle wing, rotating wingtip ailerons were fitted. The lower wing was mounted behind the undercarriage struts. The plane was powered by a 185 hp (138 kW) Daimler and was armed with twin fixed, forward-firing 0.315 in (8 mm) Schwarzlose machine guns, mounted within the pilots reach.

Lloyd 40.08 Luftkreuzer - 1917

The Lloyd Luftkreuzer was a very bizzare and unsuccessful triplane bomber which was first proposed in 1916. It was plagued with design flaws which were never solved to the degree that never let it leave the ground. It never made it past the prototype stage of development.

The prototype Lloyd Luftkreuzer was based on the requirement of LFT (Luftfahrtruppen) to develop a modern and powerful bomber powered by three engines. In August of 1915 LFT approached two companies, Lloyd and Oeffag Phönix who were awarded funding to construct two prototype triplane heavy bombers. The machine should be driven by one powerful engine in the main hull and two engines in smaller side mounted boom style fuslage. The next requirement was the ability to carry a 200 kg bomb load and endurance of at least 6 hours. Defensive armament would provided by four machine guns, two of the guns should be mounted on the main fuselage and the other two guns would be mounted in the side hulls.

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.

Aviatik (Berg) 30.27 & 30.29

Aviatik-Berg 30.27- 1918
Aviatik-Berg 30.27- 1918

When the Aviatik-Berg type 30.27 and 30.29 appeared early in 1918 it marked a radical change in design philosophy for Julius von Berg. The design was a lighter weight aircraft with a compact profile featuring a rounded cowling and forward fuselage. ALthough it was not successful it pointed toward more the form which would lead to future designs.

The design of both types was wooden construction with plywood fuselage skinning. The forward section of the aircraft was covered by light metal panels, and fabric-covered wings rounded out the design. Both the Aviatik 30.27 and 30.29 were fitted with the standard Austrian armament of twin synchronized fixed forward-firing 0.315 in (8 mm) Schwarzlose machine guns.

Aviatik-Berg 30.40- 1918

Österreichische-Ungarische Flugzeugfabrik designer Julius von Berg was working on a new lighter type of Aviatik fighter departing from their previous reliance on the heavier Austro-Daimler inline engine. The first attempt was the unsuccessful type 30.27 and 30.29 biplanes. The Aviatik-Berg 30.40 was a parasol monoplane derivative of the Aviatik 30.27. In fact many of the components came from the surviving 30.27 airframes. The prototype was built and flown during the summer of 1918. Only one example of the aircraft was built.

The Aviatik 30.40 was was a fairly standard wooden construction. The forward fuselage was covered by light metal panels and the remainder of the fuselage was skinned with plywood. The wing had fabric skinning, and steel-tube bracing struts were employed. The power for the Aviatik 30.40 was provided by a similar 160hp Steyr Le Rhone 11-cylinder rotary engine. Armament would have consisted of the standard twin synchronized fixed forward-firing 0.315 in (8 mm) Schwarzlose machine guns
