[edit] Design and development
Intended as a replacement for the Sopwith Pup,[1] the Camel prototype first flew in December 1916, powered by a 110 hp Clerget 9Z. Known as the "Big Pup" early on in its development, the aircraft was armed with two .303 in (7.7 mm) Vickers machine guns mounted in the cowl, firing forward through the propeller disc. A fairing surrounding the gun installation created a hump that led to the name Camel.[1] The top wing was flat - but the bottom wing had dihedral, so that the gap between the wings was less at the tips than at the roots. Approximately 5,490 were ultimately produced.[2]
[edit] Operational history
The type entered squadron service in June 1917 with No. 4 Squadron of the Royal Naval Air Service, near Dunkirk. The following month, it became operational with No. 70 Squadron of the Royal Flying Corps. By February 1918, 13 squadrons were fully equipped with the Camel.
Unlike the preceding Pup and Triplane, the Camel was not considered pleasant to fly. The Camel owed its difficult handling characteristics to the grouping of the engine, pilot, guns, and fuel tank within the first seven feet of the aircraft, coupled with the strong gyroscopic effect of the rotary engine.
The Camel soon gained an unfortunate reputation with student pilots. The Clerget engine was particularly sensitive to fuel mixture control, and incorrect settings often caused the engine to choke and cut out during takeoff. Many crashed due to mishandling on takeoff when a full fuel tank affected the center of gravity. In level flight, the Camel was markedly tail-heavy. Unlike the Triplane, the Camel lacked a variable incidence tailplane. The pilot was therefore required to apply constant forward pressure on the control stick to maintain a level attitude at low altitude. However the machine could also be rigged in such a way that at higher altitudes it could be flown "hands off." A stall immediately resulted in a spin and the Camel was particularly noted for its vicious spinning characteristics.
The Camel was, however, a superlative fighter. In the hands of an experienced pilot, its instability became maneuverability. The aircraft offered heavier armament and better performance than the Pup and Triplane. Its controls were light and sensitive. The Camel turned slowly to the right which resulted in a nose up attitide due to the torque of the rotary engine, but turned very sharply to the left which resulted in a nose down attitude. Because it was tail heavy, the plane also looped quickly. Agility in combat made the Camel one of the best remembered Allied aircraft of the First World War. It was said to offer a choice between a "wooden cross, red cross and Victoria Cross." Together with the S.E.5a, the Camel helped to wrest aerial superiority away from the German Albatros scouts. The Camel was credited with shooting down 1,294 enemy aircraft, more than any other Allied scout.
Major William Barker's Sopwith Camel (serial no. B6313, the aircraft in which all his victories were scored,[3]) became the most successful fighter aircraft in the history of the RAF, shooting down 46 aircraft & balloons from September 1917 to September 1918 in 404 operational hours flying. It was dismantled in October 1918. Barker kept the clock as a memento, although he was asked to return it the following day.
By mid-1918, the Camel was approaching obsolescence as a fighter, limited by its slow speed and comparatively poor performance over 12,000 feet (3650 m). It found a new lease of life as a ground-attack aircraft and infantry support weapon. During the German Offensive of March 1918, flights of Camels harassed the advancing German Army, inflicting high losses (and suffering high losses in turn) through the dropping of 25lb (11 kg) Cooper bombs and ultra-low-level strafing. The protracted development of the Camel's replacement, the Sopwith Snipe, meant that the Camel remained in service until the Armistice.
In summer 1918, a 2F.1 Camel (N6814) was used in trials as a parasite fighter under Airship R23
[edit] Variants
The Camel was powered by a variety of rotary engines during the production period.
- 130 hp Clerget 9B Rotary (standard powerplant)
- 140 hp Clerget 9Bf Rotary
- 110 hp Le Rhone 9J Rotary
- 150 hp Bentley BR1 Rotary (gave best performance - standard for R.N.A.S. machines)
- 100 hp Gnome Monosoupape 9B-2 Rotary
- 150 hp Gnome Monosoupape 9N Rotary
[edit] Engine variants
- With the Clerget rotary engine, the crankshaft remained fixed while the cylinders and attached propeller rotated around it. The result of this torque was a significant "pull" to the right. In the hands of an experienced pilot, this characteristic could be exploited to give exceptional maneuverability in a dog-fight. A 3/4 turn to the right could be done in the same time as a 1/4 turn to the left.
- The Gnome engines differed from the others in that a selector switch could cut the ignition to all but one of the cylinders to reduce power for landing. (This was because rotary engines did not have throttles and were at full 'throttle' all the while the ignition was on) On the others the engine had to be "blipped" (turned off and on) using a control column-mounted ignition switch, (blip switch) to reduce power sufficiently for a safe landing. The Clerget Engines differed from the others in that they all have throttles and were much more controlable than their counterparts.
[edit] Sopwith Camel F.1
- Single-seat fighter ("scout") aircraft.
- The main production version. Armed with twin synchronised Vickers guns.
[edit] Sopwith Camel 2F.1
- Shipboard fighter scout aircraft.
- Slightly shorter wingspan
- One Vickers gun replaced by an overwing Lewis
- Bentley BR1 as standard
[edit] Sopwith Camel "Comic" Nightfighter
Pilot seat moved to rear. The twin Vickers guns were replaced with two Lewis guns firing forward over the top wing on Foster mountings. Served with Home Defence Squadrons against German air raids. The "Comic" nickname was of course unofficial, and was shared with the night fighter version of the Sopwith 1½ Strutter.
[edit] F.1/1
- Version with tapered wings.
[edit] (Trench Fighter) T.F.1
- Experimental trench fighter.
- Downward angled machine guns
- Armour plating for protection

[edit] Survivors
There are only seven authentic Sopwith Camels left in the world, with one in the United States. It can be found at the Aerospace Education Center in Little Rock, Arkansas. Another one, beautifully restored to near-flying condition, is at the Brussels Air Museum Restoration Society (BAMRS) in Belgium. An example of a model F.1 can be found at the Polish Aviation Museum. The Camel, which is on display in the Polish Aviation Museum, serial number B 7280, at first flew in Royal Naval Air Service and then in Royal Flying Corps. Two pilots who flew this aircraft shot down 11 German planes in total. N6812, the Sopwith 2F1 Camel flown by Flight Sub Lieutenant Stuart Culley when he shot down Zeppelin L 53, is preserved at the Imperial War Museum in London. N8156 (RAF) is currently on display at the Canadian Aviation Museum. Manufactured in 1918 by Hooper and Company Ltd., Great Britain, it was purchased by the RCAF in 1924 and last flew in 1967. It is currently on static display. [4].
A replica Sopwith Camel can be found at the National Museum of the United States Air Force in Dayton, Ohio. Another replica is currently under construction by the Northern Aeroplane Workshops for the Shuttleworth Collection.[5]

[edit] Popular culture
The Camel appears in literature and popular media as:
- The single-seater scout plane flown by the Royal Flying Corps Squadron in the great First World War, semi-autobiographical, air combat book Winged Victory written by Victor Maslin Yeates.
- The fighter flown by Biggles in the novels by W.E. Johns during the character's spell in 266 squadron during the First World War. He also wrote a book, The Camels Are Coming.
- The "plane" of Snoopy in the Peanuts comic strip, when he imagines himself as a First World War flying ace and the nemesis of the Red Baron. The "Sopwith Camel" is actually his doghouse.
- The type of aircraft flown in the First World War by John and Bayard Sartoris in William Faulkner's Flags in the Dust. Under fire from a pupil of Richthofen (the Red Baron), John's Camel caught fire over occupied France. Bayard's last sight of his twin brother was of John jumping out of his fighter feet first. Faulkner also wrote about the Camel (and Sartoris) in his famous story All the Dead Pilots.
- Bartholomew Bandy flies a Camel in the first "Bandy Papers" book by Donald Jack, Three Cheers for Me.
- Microsoft Flight Simulator Series featured the Camel in versions FS3.0, FS4.0, FS5.0, FS5.1, FS95, FS98, FS2000, FS2002, FS2004, and FSX.
- First Eagles a WW1 combat simulator by Thirdwire features the Camel F1 in three different versions (110hp,130hp and 150hp)
