Gnome 7 Lambda (also Gnome Λ , Gnome 80 hp in the literature) is a French 7-cylinder rotary air-cooled aircraft engine , licensed in the UK, Germany and Russia. Installed on several dozen types of aircraft during the First World War . According to the manufacturer, with a working volume of 12 liters, he developed a capacity of up to 80 liters. with. (60 kW), however, test results showed that this figure was somewhat overestimated. [2]

There was a 14-cylinder twin-row engine modification, the Gnome 14 Lambda-Lambda , or Gnome 160 .
In the UK, nearly 1,000 licensed copies were issued, mostly (967) at the Daimler Motor Company in Coventry . Most of the engines released were installed on Avro 504 , Bristol Boxkite and Bristol Scout .
In Germany, the Oberursel company produced under license both a 7-cylinder ( Oberursel U.0 (U - Umlaufmotor, rotary engine)) and later a 14-cylinder modification ( Oberursel U.III ).
In pre-revolutionary Russia, Gnom engines were manufactured at the Riga Motor plant, which was located in the Sassengoff area before evacuation, and were also called Kalep-Gnom, named after the director Theodore (Fedor) Kalep . In the Riga version, the compression ratio was brought to 4.0; power is up to 85 l. sec., and the unit itself was 7 kg lighter than the original.
The original version of the engine was produced by the Moscow branch of the Gnom company (now, after several reorganizations and renaming, it is part of the Salyut gas turbine construction center ).

Surviving Engines
One of the surviving engines, the original Gnome 7 Lambda, is mounted on a replica of the Sopwith Tabloid in the Grahame-White hall of the Royal Air Force Museum of London. [five]
Another engine is located at the SNECMA Museum near the Melon-Villaroche airfield, France. [6]
