A.Jackson De Havilland Aircraft since 1909 (Putnam)

Royal Aircraft Factory B.S.1

   The last aircraft designed by Geoffrey de Havilland and his team before he left to join the Aircraft Manufacturing Co. Ltd. was the B.S.1 single seat biplane flown early in 1913. Powered by a 14 cylinder, two row Gnome rotary, it was the first aeroplane in the world specifically designed as a fast single seat scout and as Bleriot was said to have originated the tractor biplane, was known as the Bleriot Scout, or B.S.1.
   Its wooden, circular section monococque fuselage, a masterpiece of the cabinet maker's art and years ahead of its time, merged smoothly into the lines of the closely cowled engine to give the B.S.1 a very good streamlined shape. Lateral control was by warping the single bay wings and the tail unit featured a diminutive rudder, without fixed fin, mounted above a one-piece tailplane and elevator.
   For its day the B.S.1 was very fast and in March 1913 its designer, now Lt. de Havilland, Special Reserve, was timed over the speed course at 91.4 m.p.h. Unfortunately the rudder was far too small for the considerable keel surface of the deep front fuselage and directional control was poor. Consequently, later on the day of the speed trials, it went out of control in a turn and de Havilland was injured as it struck the ground in a flat spin.

    The remarkably clean, almost visionary Royal Aircraft Factory BS I was another creation of designer/pilot Geoffrey de Havilland and made its debut in early 1913. Extolled by the noted early military aviation historian, J.M.Bruce, as being the sire of all future single seat fighters of World War I, the BS I had what can only be described as a vivid performance, for its day, being capable of 92mph, coupled to a 900 feet per minute initial rate of climb. All this on the power of an 80hp Gnome! In its earliest form, seen here, the BS I's rudder, unaided by any fin, was simply inadequate to provide effective directional control and anyway was too weak, as it demonstrated by breaking away on 27 March 1913, breaking de Havilland's jaw in the ensuing crash. Rebuilt with a more effective tail unit, the aircraft became the SE 2.
