Tracings of aircraft, engines and ancilliary equipment designed and built at the Royal Aircraft Factory, Farnborough, from 1911 to 1918; also a number of drawings of aircraft and equipment which were of interest to the Royal Aircraft Establishment, but not designed or built at Farnborough. Some of the equipment is dated as late as 1944.
The following drawings are among those that have been preserved and relate to large numbers of Service aircraft such as B.E.2's, F.E's, R.E's and S.E's. (1) R.A.F. 1a - 8 cyl. air cooled 'V' of 90 H.P. (2) R.A.F. 3a - 12 cyl. water cooled 'V' of 150 H.P. (3) R.A.F. 4a - 12 cyl. air cooled 'V' of 150 H.P.(4) R.A.F. 8-9 cyl. air cooled radial.
Other drawings included are superchargers (all the basic types for both piston and turbine engines) and catapaults ( most of the land and ships catapults were designed and constructed by the Royal Aircraft Establishment).
In addition to the foregoing a vast range of research and development was carried out on engine cylinders, fuels, fuel injection, starters and other engine accessories and much of the information can be ascertained from the list of drawings or by reference to those Engine Dept files which have been retained.
The majority of material in this series is dated from 1911 to 1918, but the series also contains some later material.
