The Sopwith Camel is a British First World War single-seat biplane fighter aircraft that was introduced on the Western Front in 1917. It was developed by the Sopwith Aviation Company as a successor to the Sopwith Pup and became one of the best-known fighter aircraft of the Great War. Pilots flying Camels were credited with downing 1,294 enemy aircraft, more than any other Allied fighter of the conflict. Towards the end of the war, Camels lost their edge as fighters and were also used as a ground-attack aircraft.
The Monosoupape, was a rotary engine design first introduced in 1913 by Gnome Engine Company. It used a clever arrangement of internal transfer ports and a single pushrod-operated exhaust valve to replace the many moving parts found on more conventional rotary engines, and made the Monosoupape engines some of the most reliable of the era. British aircraft designer Thomas Sopwith described the Monosoupape as "one of the greatest single advances in aviation".
The Sopwith Triplane is a British single seat fighter aircraft designed and manufactured by the Sopwith Aviation Company during the First World War. It has the distinction of being the first military triplane to see operational service.
Clerget was the name given to a series of early rotary aircraft engine types of the World War I era that were designed by Pierre Clerget(fr). Manufactured in France by Clerget-Blin and in Great Britain by Gwynnes Limited they were used on such aircraft as the Sopwith Camel and Vickers Gunbus.

The de Havilland Gipsy Queen is a British six-cylinder aero engine of 9.2 litres (560 cu in) capacity that was developed in 1936 by the de Havilland Engine Company. It was developed from the de Havilland Gipsy Six for military aircraft use. Produced between 1936 and 1950 Gipsy Queen engines still power vintage de Havilland aircraft types today.
The Le Rhône 9J is a nine-cylinder rotary aircraft engine produced in France by Gnome et Rhône. Also known as the Le Rhône 110 hp in a reference to its nominal power rating, the engine was fitted to a number of military aircraft types of the First World War. Le Rhône 9J engines were produced under license in Great Britain by W.H. Allen Son & Company of Bedford, and in Germany by Motorenfabrik Oberursel where it was sold as the Oberursel Ur.II.
The Le Rhône 9C is a nine-cylinder rotary aircraft engine produced in France by Société des Moteurs Le Rhône / Gnome et Rhône. Also known as the Le Rhône 80 hp in a reference to its nominal power rating, the engine was fitted to many military aircraft types during the First World War. Le Rhône 9C engines were also produced under license in Great Britain, the United States and Sweden.
The Bentley BR.1 was a British rotary aircraft engine of the First World War. Designed by the motor car engine designer W. O. Bentley, BR.1s powered the majority of Sopwith Camels flown by the Royal Naval Air Service (RNAS).
The Bentley B.R.2 was a nine-cylinder British rotary aircraft engine developed during the First World War by the motor car engine designer W. O. Bentley from his earlier Bentley BR.1. The BR.2 was built in small numbers during the war, its main use being by the Royal Air Force in the early 1920s.
The Pobjoy R is a British seven-cylinder air-cooled radial aircraft engine designed and built by Pobjoy Airmotors. Introduced in 1926, it was a popular engine for ultralight and small aircraft in the 1930s. A notable feature of the Pobjoy R was the propeller reduction gear which allowed the small engine to operate at more desirable higher speeds.
The Rotec R3600 is a nine-cylinder radial engine built by Rotec Aerosport Pty Ltd in Australia. Initially released in 2005, it was a followup of the 7-cylinder Rotec R2800 released five years earlier. Both this engine and its smaller cousin have been frequently used as both replacement engines for vintage World War 1 aircraft, and reproduction aircraft from the same vintage. Some notable aircraft this engine has been used in are the Fokker Triplane, Sopwith Camel and the Nieuport 17.
The Rotec R2800 is a seven-cylinder 110 hp radial engine built by Rotec Aerosport Pty Ltd in Australia. The R2800 was Rotec's first engine offering when they first opened their doors in 2000. In 2005, Rotec released a more powerful variant, the Rotec R3600 adding two more cylinders for a total of nine and increasing the rated horsepower to 150. This engine and its larger cousin are frequently used on World War I aircraft, both vintage and modern reproductions. Some notable repro WW I aircraft this engine has been used in are the Fokker Triplane, Sopwith Camel and the Nieuport 17. Other experimental / homebuilt aircraft have also been fitted with the Rotec 2800, including the Kitfox Model 7; a popular kit aircraft with over 5,000 examples of all variants completed. It is unknown how many Kitfox aircraft are equipped with the Rotec 2800 engine.
The Green C.4 was a British four-cylinder, water-cooled aero engine that first ran in 1908, it was designed by Gustavus Green and licensed by his Green Engine Co for manufacture by Aster Engineering. The engine was one of two Green designs to win a government prize.
The Gnome 7 Omega is a French seven-cylinder, air-cooled aero engine produced by Gnome et Rhône. It was shown at the Paris Aero Salon held in December 1908 and was first flown in 1909. It was the world's first aviation rotary engine produced in quantity. Its introduction revolutionized the aviation industry and it was used by many early aircraft. It produced 37 kW (50 hp) from its 8 L (490 cu in) engine capacity. A Gnome Omega engine powers the 1912 Blackburn Monoplane, owned and operated by the Shuttleworth Collection, the oldest known airworthy British-designed aeroplane worldwide. A two-row version of the same engine was also produced, known as the Gnome 14 Omega-Omega or Gnome 100 hp. The prototype Omega engine still exists, and is on display at the United States' National Air and Space Museum.
The Gnome 7 Lambda was a French designed, seven-cylinder, air-cooled rotary aero engine that was produced under license in Britain and Germany. Powering several World War I-era aircraft types it was claimed to produce 80 horsepower (60 kW) from its capacity of 12 litres although recorded figures are lower.
The Clerget 11Eb was an 11-cylinder rotary aircraft engine of the World War I era designed by Pierre Clerget. Powering Sopwith types it was nominally rated at 200 horsepower (150 kW).
The Clerget 7Z was a seven-cylinder rotary aircraft engine of the World War I era designed by Pierre Clerget. First appearing in 1911 it was nominally rated at 80 horsepower (60 kW). In addition to the 600 engines built in France by Clerget-Blin, 347 examples were built under license in Britain by Gordon Watney & Co Ltd of Weybridge and Gwynnes Limited of Hammersmith.
The Clerget 16X was an experimental French 16-cylinder X engine built in about 1918.
The Nieuport 17bis C.1 was a World War I French single-seat sesquiplane fighter that was produced under licence in the United Kingdom in small numbers for the Royal Naval Air Service.
