The Gnome 7 Omega (commonly called the Gnome 50 hp) is a French seven-cylinder, air-cooled aero engine.[2] It was shown at the Paris Aero Salon held in December 1908 and was first flown in 1909. It was the world's first[1] rotary engine produced in quantity. Its introduction revolutionized the aviation industry[3] and it was used by many early aircraft. It produced 50 horsepower (37 kW) from its capacity of 8 litres (488 cubic inches).[4] A Gnome Omega engine powers the 1912 Blackburn Monoplane, owned and operated by the Shuttleworth Collection, the oldest known airworthy British-designed aeroplane worldwide.[5] 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.[6]
