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 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 which basically adds two more cylinders for a total of nine and increases the rated horsepower to 150. Both this engine and its larger cousin have been frequently used as both replacement engines for vintage World War I aircraft, and reproduction aircraft from the same vintage. 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.

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.
