Royal Aircraft Factory S.E.2

The S.E.2 was a rebuild of the unarmed B.S.1, which was designed at Farnborough by Geoffrey de Havilland assisted by H P Folland and S J Waters, and flown in early 1913. Designated as a "Bleriot Scout", the B.S.1 was an attractive single-bay equi-span biplane with a circular-section fuselage which was of monocoque construction aft of the single-seat cockpit. Power was provided by a partially-cowled 100hp Gnome rotary engine. The B.S.1 achieved 148km/h and a climb rate of 4.6m/s in early tests, but was badly damaged on 27 March 1913. It was then rebuilt with a redesigned tail unit that included a semicircular tailplane with a lifting profile, divided elevators, a small fin and large rudder. With a fully-cowled 80hp Gnome nine-cylinder rotary engine, the aircraft flew again in October 1913, being redesignated S.E.2 as a Scouting Experimental (although the S.E. series had earlier been intended for "Santos Experimental", of canard configuration). RFC handling trials took place (with No 5 Squadron) early in 1914, after which the S.E.2 was again rebuilt, with a more conventional rear fuselage of wooden construction and fabric covering, larger fin and rudder, constant-chord tailplane and other smaller changes. Taken to France (by No 3 Squadron) later in 1914, the S.E.2 was fitted with two Army rifles firing at outward angles to clear the propeller, and other (revolver) armament was also tried during the several months it remained with the squadron.

FORGOT TO MENTION THE 'SKEWED' ARMY RIFLES. THE PERFECT TOUCH IN 1913.

DICK GREENWOOD, 17.01.2010

THIS IS ANOTHER AMAZINGLY ADVANCED AIRPLANE FOR 1913. I HAD BEEN ADMIRING THE 1916 'SUPERMARINE'. THIS IS THE FIRST I'VE SEEN IN A 'MONOCOQUE'STRUCTURE. AMAZING. FOREVER IN AWE OF ENGLISH ENGINEERING .
