Robey Peters R.R.F.2

Tests conducted in the USA led the British Admiralty to adopt the Davis recoilless gun for the RNAS, several types of aircraft being designed around this immense weapon, essentially for the anti-Zeppelin role. Among these was the Robey Peters R.R.F.25, designed by J A Peters for Robey & Company. Powered by a 250hp Rolls-Royce 12-cylinder Vee-type water-cooled engine (later to be named Eagle), the R.R.F.25 was an unequal-span two-bay biplane with a crew of three comprising a pilot and two gunners. The pilot was accommodated far aft, immediately ahead of the vertical tail, and the gunners occupied nacelles suspended beneath the upper wing. The port nacelle accommodated a 7.7mm Lewis gun and the starboard nacelle housed a two-pounder version of the Davis gun which exceeded 2.13m in length. Eight shells for the gun were fitted into the nacelle and two more in the adjacent wing. Two prototypes were ordered, the first of these flying in September 1916. It suffered minor damage as a result of turning over during the take-off run for what was to have been its second flight, and when it did succeed in getting airborne once more a fire at low altitude resulted in a crash in which it was destroyed. The second prototype, referred to as the Mk II, featured a new equispan three-bay wing cellule, introduced a fixed tail fin, and side windows were added for the pilot. Overall span was reduced by 61cm and wing area was increased by 5.89m2. It was intended that a Davis gun be carried in each nacelle. This aircraft was, in fact, cancelled by the Admiralty, but was completed nonetheless in January 1917 and flown during the course of the month. It stalled on take-off, however, and crashed, further work on the aircraft being finally abandoned.

I hazard the guess that this aircraft was somewhat underpowered.

I would like to find out more about this plane as J.A. Peters was my grandfather and I am just finding out about him and his many aircraft. He later became a pioneer motor-cycle designer.
