Between 1911 and 1918 the Royal
Aircraft Factory produced a number of aircraft designs. Most
of these were essentially research aircraft, but a few actually
went into mass production, especially during the war period.
Some orders were met by the factory itself, but the bulk of production
was by private British companies, some of which had not previously
built aircraft.Up to about 1913 the designation letters referred
to the general layout of the aircraft, derived from a French
manufacturer or designer famous for that type:
S.E. = Santos Experimental (Canard
or tail-first layout)
B.E. = Blériot Experimental (Tractor or propeller-first
layout)
F.E. = Farman Experimental (Pusher or propeller behind the pilot
layout)
From 1913/14 onwards this was changed to a designation based
on the role for which the aircraft was designed:
A.E. = Armed or Armoured Experimental
C.E. = Coastal Experimental (e.g. Royal Aircraft Factory C.E.1
prototype only)
F.E. = Fighting experimental (although they remained "Farmans"
in the sense of being pushers)
N.E. = Night Experimental (e.g. Royal Aircraft Factory N.E.1
prototype only)
R.E. = Reconnaissance experimental (two-seat machines)
S.E. = Scout experimental fast single-seat aircraft.
The B.S.1 of 1913 was a one-off anomaly, combining both systems:
Blériot (tractor) Scout (fighter).
R.T. & T.E. were also used
for strictly one off prototypes. |
