WWI Entente Powers' Aircraft

Aviation advanced rapidly during World War I, 28 June 1914 to 11 November 1918. The following photographs in alphabetical order illustrate the improvements in aircraft during the war. The Entente Powers were led by France, Russia, the United Kingdom, and later Italy (from 1915) and the United States (from 1917). Russia withdrew from the war after the revolution in 1917.

Operational details,specifications and historical facts on these aircraft are available at http://www.wikipedia.org under the subject "Aviation in WWI".

Airco DH-1 Early Pusher Fighter
At the beginning of WWI, a major limitation was the mounting of machine guns. They could not fire directly forward without hitting the propeller.

Airco DH-2 Early Pusher Fighter
One early solution was the use of "pusher" types with a gunner in the forward cockpit having an unobstructed field of fire.

Sqn Cdr E. H. Dunning landing on HMS Furious 1917
On August 2, 1917, Sqn Cdr Edwin H. Dunning RN was the first pilot to land an aircraft on a moving ship when he landed his Sopwith Pup on HMS Furious. He was killed five days later when a tyre burst, throwing his plane overboard.

HMS Furious 1916
HMS Argus was built from the start with an unobstructed flight deck. Prior to that, the aircraft carrier HMS Furious had been built with a separate flight deck ahead of the main superstructure. After Dunning's accident, a second flight deck was added aft of the superstructure. Both carriers saw service in WW II.

Nieuport 27
The Nieuport 11 is famous as the French answer to the "Fokker Scourge" of 1915. It entered service in January 1916 and progressed through the 17, 27, and 28 models with increasing power and performance throughout WWI. The 28 was the first fighter used by by the US and considered by some superior to the SPAD.
Nieuport 11C January 1916

Nieuport 11 Fighter (Replica)
Rotary engines of 80 to 120 HP were used by both sides to power light-weight fighters. Advantages were a high power to weight ratio, low vibration, and efficient air cooling. Disadvantages were little to no throttability. Power was controlled by intermittently cutting ignition to some or all cylinders by a "blip" button on the stick. Fuel was shut off to descend from altitude.

Royal Aircraft Factory FE-2B, 1915

Royal Aircraft Factory RE-8
Together with the Camel, the SE-5 was instrumental in regaining allied air superiority in the summer of 1917 - and maintaining this for the rest of the war - ensuring there was no repetition of "Bloody April" 1917.
Royal Aircraft Factory SE-5, 1917, over 5000 built

Royal Aircraft Factory SE-5A ready to taxi, 1917
Although the SE-5 reached the Western Front in 1917 before the Sopwith Camel and had better overall performance, problems with its Hispano-Suiza engine caused a chronic shortage of SE-5s until well into 1918.

The Sopwith Camel was famous for its maneuverability but not considered pleasant to fly. Nevertheless, it was successful in combat and had heavier armament and better performance than than the preceding Pup and Triplane.
