Royal Aircraft Factory B.E.2.
Type: two-seat reconnaissance and bomber aircraft.
Royal Aircraft Factory B.E.2, B.E.2a und B.E.2b
The initial B.E. model manufactured by the Army Aircraft Factory was the BE.1, developed by Geoffrey de Havilland and F. M. Green during the second half of 1911.
Using the Army Aircraft Factory naming method implemented in November 1911the characters B.E. represented Bleriot Experimental. Nevertheless, it was simply to point out that the B.E. models had been general-purpose 2-seat tractor biplanes; they had no layout or other reference to planes of Bleriot origin.
Apparently, it was said to be a remodeling of a Voisin biplane; the truth is, virtually its solely reference to the Voisin was the latter’s 60 h.p. Wolseley power plant, and even this was switched for a 60 h.p. Renault a little while following the B.E.1’s first flight on 1 January 1912. The B.E.1 afterwards served with the Royal Flying Corps, using the official serial number 201.
The B.E.2, which came out in February 1912, was an advanced model with equal-span unstaggered wings and a 70 h.p. Renault engine; it had been a two-seater, with the pilot in the rear cockpit. On 12 August 1912 the B.E.2 was flown to a new British altitude record of 10,560 ft. (3,219 m.), and afterwards that month it demonstrated its superiority to the Cody biplane which had formerly triumphed in the Military Trials at Larkhill. A small purchase for 4 B.E.2s had been applied with Vickers almost 3 months prior to this, and the first of these aircrafts had been transferred to the Royal Flying Corps in February 1913.
Additional requests succeeded, and many production planes at this point were built as B.E.2as, having unequalspan wings, extra decking round the front cockpit and a modified fuel system. Prior to the outbreak of World War One the B.E.2/2a was in service with 3 Royal Flying Corps squadrons, and a minimum of one such plane was in the ownership of the Royal Navy Air Service in September 1913.
After the outbreak of World War One, the B.Es. were in action in France with Nos. 2, 4, 6, 8, 9 (Wireless) and 16 Squadrons of Royal Flying Corps, and also the previous Royal Navy Air Service Eastchurch Squadron in the Ostend/Dunkirk region. These were accompanied by the B.E.2b, which differed in its elevator and rudder handles together with refurbished top-decking and cockpit shapes to provide improved coverage to the crew. The primary air Victoria Cross of World War One had been honored, posthumously, to Lt. W. B. Rhodes-Moorhouse of No.2 Squadron, who, regardless of his injuries, moved his B.E.2 back successfully from a bombing strike on the railway station at Courtrai on April 26, 1915. Yet another officer of No.2 Squadron had, on 13 August 1914, piloted the initial British aircraft (a B.E.2a) to land in France following the outbreak of world war one.
The B.Es of the Royal Navy Air Service were chosen regularly for bombing, transporting one single 100 lb. bomb or 3 smaller ones beneath the fuselage. Earlier B.Es. had no mounted defensive armament, the merely defense becoming rifles or revolvers held by the observer. These regularly shot incendiary bullets in attempts to blast down German balloons and Zeppelins. Earlier B.Es. saw the vast majority of their operational service in France, despite the fact that minor quantities of Royal Flying Corps aircrafts had been flown in Egypt and one or two Royal Navy Air Service planes took part in the Dardanelles campaign.
You can find 164 identified serial number allocations for B.E.2/2a/2b planes, produced by 9 British suppliers; undoubtedly even more than these were produced, but existence documents cause it to be hopeless to provide more accurate statistics. Ultimate B.E.2b production were made at the end of fall 1916, whereby the model had been outdated for no less than one year. Late-production planes, and previously aircrafts removed from front-line service, however, worked an additional valuable time in a training role.
Royal Aircraft Factory B.E.2c and B.E.2d
All through its beginning lifetime the Royal Aircraft Factory as well as antecedents had been interested – one could even state passionate – with the development of a fundamentally stable airplane. They theorized, quite correctly, that this kind of plane could be simpler and far better to fly; without doubt these folks were furthermore affected by the War Office’s viewpoint that planes were definitely solely useful for reconnaissance, for the purpose a steady-flying plane was in fact considerably better.
Unfortunately, while combat experience in France had been virtually every day demonstrating this perspective to be incorrect, from an operational view, the Factory possibly wasn’t informed (or, if it had been, it made a decision to overlook) the truth that it was the extremely stability of the B.E. that was causing its downfall. Versus the agile, front-gunned Fokker Eindecker (monoplane) fighters the B.E.2 was almost helpless: it had been way too stable to outmaneuver the enemy, not fast enough to escape from him as well as, because it required 45 minutes to arrive at its limited ceiling of 10,000 ft. (3,048 m.), didn’t have any hope in any way of outclimbing him.
The B.E.2 model had been the primary mount of one of the Factory’s top experimental pilots, Edward Busk, throughout his studies into the matter of inherent stability. The key outcomes of his studies took reflection in the B.E.2c, which was first flown at the beginning of summer of 1914. This model had equal-span wings with marked forward stagger and double ailerons instead of the warp handle of the previous B.Es.; vertical fin area has also been improved. A handful of B.E.2cs arrived at France late in 1914, however the initial unit completely equipped with them (No.8 Squadron) didn’t appear before April 1915.
By now the R.A.F.1a powerplant (engineered from the Renault engine of previous B.E.2cs) took over as the common engine, along with an ordinary Vee-type undercarriage exchanged the previous wheeland-skid design. Bomb load of Renault-powered B.E.2cs comprised 4 x 25 lb. Cooper bombs hanging under the nose; R.A.F. 1a-engined planes held 2 x 112 lb. or 10 x 20 lb. bombs using the wings; using the more heavy load they were generally flown solitary from the rear seat. The B.E.2c ultimately were in action on the Western Front with No. 1 Wing Royal Navy Air Service along with more than 12 Royal Flying Corps squadrons.
It was also used as a bomber or reconnaissance plane in Macedonia and the Middle East, and Naval B.E.2cs worked as bombers and anti-submarine planes in the Dardanelles as well as the Aegean.
Starting from spring 1916 the B.E.2d started to link up with it operating. This had a big gravity fuel tank under the top wing, which improved its range having a similar load to the B.E.2c, however it required almost two times as long as the B.E.2c to arrive at 10,000 ft. The newest model was considerably improved protected, the observer occupying its rear cockpit equipped with a free-firing Lewis machine-gun. A handful of B.E.2ds were delivered to Escadrille 6 of the Belgian Aviation Militaire, being equipped with 150 h.p. Hispano-Suiza motors.
In spite of its disappointed reputation as ‘Fokker fodder’ in France, the B.E.2c appreciated more success at Britain. Here its stability made it an excellent weapon platform for night combat, and, flown solitary from the back cockpit, by having an upward-firing Lewis machine-gun on top of the top wing, it reached several good results as a Home Defence fighter, including the wrecking of 7 Zeppelins.
The message of the victims in France, nevertheless, wasn’t realized: it’s simply outcome appeared to be to boost manufacturing, and the model was still in front-line service when the final B.E.2c was produced in July 1917. An exact number can’t be presented, however an overall manufacturing of B.E.2c/2d approximately 1,300 planes seems very likely. Both of these types continued to be operating until November 1918, latterly in a training role.
Royal Aircraft Factory B.E.2e
The ultimate manufacturing type in the ill-starred B.E.2 series, the B.E.2e, was a minimal faster and it was finer on the controls than its forerunners, however wasn’t any serious advancement. Certainly, it had a worse climb than the B.E.2c and, strangely, reverted to the outmoded back-to-front seating design, hence seriously restricting the use that the observer could make of the defensive MG. Structurally, it differed substantially from earlier types, getting single-bay wings with blunt, raked tips along with a pronounced alteration in span between the lower and upper wings. The tailplane and elevator tips had been furthermore raked back, and a bigger, more curved vertical fin was equipped.
Several B.E.2c/2d deals had been reversed to choose B.E.2es, the initial planes of the brand new type being sent to the Royal Flying Corps in July 1916. They afterwards were in action in all of the squadrons which had used previous B.E.2 models, as well as were in action in Macedonia and India and also on the Western Front.
Around 95 Royal Flying Corps B.E.2es were employed in the Royal Navy Air Service for training tasks; a number of these were run by 75 h.p. Rolls-Royce Hawk motors. In August 1918 the U.S. Navy acquired 12 B.E.2es to be used as trainers.
It is well-nigh hopeless to provide a manufacturing breakdown for the B.E.2 models. The manufacturing programme was really wide-ranging, and lots of agreements possibly stay unconfirmed or given a combination of more than one models. Besides the Royal Aircraft Factory, no less than 22 different British companies are recognized to have taken part in the fabrication programme, the most important contributors being the British & Colonial Aeroplane Company., Ruston Proctor & Company., Vickers Limited., Vulcan Motor & Engineering Company., as well as. G. & J. Weir.
Serial allocations can be verified for 3,535 B.E.2-type planes, however most likely even more than this quantity were produced. This indicates that a B.E.2e output upward of 1,800, of which about 50 % tend to be to have been used on training duties, is a realistic approximation.
