The Vickers F.B.24 was a British two-seat fighter aircraft of the First World War. Only a few prototypes were built, as, although it had good performance, the Bristol F.2 Fighter was preferred.

Design and development

In the early years of the First World War, Vickers Limited designed a number of aircraft to use the 150 hp (112 kW) Hart radial engine, the development of which was being funded by Vickers, including two single-seat fighters, the F.B.12 pusher and the tractor F.B.16. [1] A third design planned to use the Hart was the F.B.24, a two-seat fighter reconnaissance aircraft. [2]

The Hart engine proved to be unreliable, however, and was abandoned prior to the first prototype being completed in December 1916, and it became necessary to find a new powerplant for the F.B.24, with the Hispano-Suiza 8 being chosen. [3] The first two prototypes, the F.B.24A and F.B.24B used a 150 hp Hispano-Suiza, [4] with the first probably flying in March 1917. [5] but were converted to use a 200 hp (149 kW) Hispano-Suiza, becoming the F.B.24D. The F.B.24D was a two-bay biplane with a rectangular section fuselage. The pilot and observer/gunner sat close together in separate open cockpits, with the pilot directly under the upper wings. Despite transparent panels built into the upper wings, the pilot's view was very poor. [6]

The F.B.24C was similar to the Hispano-Suiza powered aircraft, but was slightly larger and heavier, and was powered by a 275 hp (205 kW) Lorraine-Dietrich 8Bd water-cooled V8, with the cylinder blocks being enclosed in bulky fairings that protruded from the upper corners of the cowling, further restricting the pilot's view. The type was tested by the French, and although Vickers claimed good performance, the French found the aircraft's climb performance not as claimed by Vickers, and the type was not adopted. [7] The F.B.24E was an attempt to improve the poor view for the pilot, with the fuselage being raised so that the top was level with the upper wing, and the pilot sitting with his head protruding through the gap between the two wing spars. [8]

The final version was the F.B.24G. This was of similar layout to the F.B.24E, but was larger still, and was powered by a 375 hp (280 kW) Lorraine-Dietrich V12 engine, the single example being built by Darracq in France, not flying until after the end of the war. [9]

Sopwith Dolphin British WW1 biplane fighter aircraft

The Sopwith 5F.1 Dolphin was a British fighter aircraft manufactured by the Sopwith Aviation Company. It was used by the Royal Flying Corps and its successor, the Royal Air Force, during the First World War. The Dolphin entered service on the Western Front in early 1918 and proved to be a formidable fighter. The aircraft was not retained in the postwar inventory and was retired shortly after the war.

Blériot-SPAD S.61

The Blériot-SPAD S.61 was a French fighter aircraft developed in 1923. Designed by André Herbemont, the S.61 was a conventional biplane, abandoning the swept upper wing used by Herbemont in several previous designs. The prototype S.61 was evaluated by the French Air Force alongside the S.51 as a potential new fighter, but like its stablemate, was rejected. The Polish Air Force was impressed enough to order 250, as well as purchase licences for local production. The Romanian Air Force also ordered 100 aircraft. About 30 were built in Poland, by the CWL.

Like other Levasseur naval designs of the day, it incorporated several safety features in case of ditching at sea. Apart from small floats attached directly to the undersides of the lower wing, the main units of the fixed, tail-skid undercarriage could be jettisoned in flight, and the underside of the fuselage was given a boat-like shape and made watertight.
