H.Taylor Fairey Aircraft since 1915 (Putnam)

F.2

   The first aircraft to be both designed and built by the Fairey Aviation Company was a twin-engined three-seat landplane ordered by the Admiralty. This has been generally described as a long-range fighter and general-purpose aircraft, but it could also have been developed as a bomber. It was not the first aircraft to be built by the company, which made a start with a sub-contract order for twelve Short Type 827 floatplanes. These, built in 1915-16 and tested at Hamble by Sydney Pickles, carried the serial numbers 8550-8561 and the Fairey constructor’s numbers F.4-15. Before the completion of the fighter a start had also been made on a contract for one hundred Sopwith 1 1/2-Strutters.
   A fair amount of information about the F.2, in the form in which it finally appeared and was flown, can be obtained from descriptions, photographs and drawings of the period, but not much is known with certainty about the earlier versions of the project, design work on which is believed to have been started in November 1915. Four serial numbers, 3702-3705, were allocated by the Admiralty for two versions. One, it has been recorded, was to have had a tractor and the other a pusher layout. Two were to have been powered by 200 hp engines produced by Brotherhood Ltd. Three schemes were worked on by Fairey: these were for 3702 (F.1), 3704 (F.2) and 3705 (F.3). The first and third had not got beyond the wing-detailing stage before a requirement for wing-folding was introduced and the designs were not proceeded with.
   The most interesting fact about these initial proposals is that at least one, F.2, was planned with tandem-mounted engines within the fuselage and driving outboard propellers through a chain-and-sprocket system. In the case of the F.2 the propellers were pushers and the wing-folding requirement meant that the layout had to be revised to provide a tractor arrangement. This may well have been less mechanically attractive and the buried-engines plan was later dropped in favour of a conventional design with two wing-mounted powerplants - 190 hp Rolls-Royce Falcon twelve-cylinder vee liquid-cooled engines driving tractor propellers. In this form the F.2 went ahead to the prototype stage.
   This one-and-only prototype, assembled in the wooden shed on the site where the company’s factory was to be completed 18 months later, may have been flown initially, probably in straight hops, from the adjoining field at Harlington. The first official flight was, however, made by Pickles from Northolt, where it had been reassembled, on 17 May, 1917. Admiralty interest in the project had by then waned and no further progress was made.
   The F.2 was a three-bay biplane with long upper-wing extensions braced from kingposts above the outer interplane struts, and with a substantial four-wheel ‘bedstead’ undercarriage to simplify landings at night and/or to lessen the chances of nosing-over on rough ground. The wings folded from a point outboard of the Falcon engines - which, cleverly enough, were arranged to drive ‘handed’, or opposite-rotating, propellers to eliminate torque reaction and thus reduce the tendency to swing. The single tailplane carried twin fins and rudders. Armament consisted of Lewis guns on Scarff rings for the forward and aft gunners; bombs could be carried on external racks.
   No record appears to remain of the requirements which the design of the F.2 was intended to meet. Large, relatively slow, multi-engined, multi-seat fighters had not proved, nor were to prove, suitable for a conventionally offensive role in air fighting, but the F.2 might well have had value for night attacks on Zeppelin raiders and, perhaps, for specialized deep-penetration operations. The Royal Naval Air Service was, from 3 September, 1914, until March 1916, wholly responsible for the air defence of Great Britain. The RNAS also played an important, but often forgotten, part in the war on the Western Front and pioneered what would now be known as strategic bombing.
   Span 77 ft (23-5 m); length 40 ft 6 in (12-3 m); height 13 ft 6 in (4.1 m); total wing area 814 sq ft (75-6 sq m). Loaded weight 4,880 lb (2,213 kg). Maximum speed at sea level 93 mph (150 km/h); landing speed 38 mph (61 km/h). Climb to 5,000 ft (1,524 m) 6 min. Endurance 3 hr 30 min.
