The appearance in 1917 amongst the equipment
of the Royal Flying Corps of the new two seats Bristol F.2B Fighter
marked one of British aviation's greatest successes. Together with
other outstanding designs of that time - the Camel, the S.E.5a,
and the D.H.4 - it enabled the R.F.C. to gain its desired advantage
in the air. However the delivery of new planes to squadrons was
constantly up against a number of problems, not the least of which
was the lack of engines in great enough quantities. The Rolls Royce
Falcon engine installed in the F.2B was well proven, but Rolls Royce
which at that time was developing several types of engine simultaneously,
physically could not make enough engines, as were called for by
all the various designs produced by the aircraft companies. The
British War Office recommended the aircraft manufacturers to try
alternative powerplants, and so the Bristol Company decided to adapt
the F.2B design for the Hispano Suiza and Sunbeam Arab engines.
The Arab was also intended for the S.E.5a fighter, but this idea
was rejected in due course. Development at Bristol faced constant
and numerous obstacles, with the result that the F.2B Fighter with
the new engine raised into the air for the first time only in 1918.
From the new engine, improvement was expected in certain characteristics
of the aircraft. But this did not happen, mainly because one engine
failed to live up to expectations, the Arab: in the air it vibrated
severely, and a unsuitable radiator which had been created for the
300 h.p. Hispano Suiza engine further worsened the situation. Up
to the end of war there was time to build about 800 Bristol F.2B
Fighters (from an overall 4,900 Bristol Fighters) fitted with the
Sunbeam Arab. However, only insignificant numbers reached the Western
Front.
The great bulk was at once transferred to training schools and Home
Defense. On July 23rd, 1919, under the arrangements for demilitarization
machines of this type were recognized as having become obsolete
and designated for breaking up. However, the 'classic' Bristol F.2B
Fighter, equipped with the Rolls Royce Falcon, was still a potent
machine - it continued to fly until the 1930s.
