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 (720 cubic inches) although recorded figures are lower.〔Lumsden 2003, p. 151.〕 Just under 1,000 units were produced in Britain, the majority (967) by the Daimler Company of Coventry. A 14-cylinder variant was known as the Gnome 14 Lambda-Lambda. In Germany Motorenfabrik Oberursel license-built the seven-cylinder engine as the Oberursel U.0 and later copied the 14-cylinder design and designated it as the Oberursel U.III. ==Variants== ;Gnome 7 Lambda :Seven-cylinder, single-row rotary engine. ;Gnome 7 Lambda (long stroke) :Increased stroke of 145 mm (5.7 in) to raise the compression ratio to 3.87:1, and total displacement to 12.26 litres. ;Gnome 14 Lambda-Lambda :14-cylinder, two-row rotary engine using Lambda cylinders. 160 hp (120 kW). ;Motorenfabrik Oberursel U.0 :German production of the Gnome 7 Lambda - had a 124mm cylinder bore and 140mm piston stroke for a total displacement of 11.52 litres, external diameter of 1.020 meters. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gnome Lambda」の詳細全文を読む スポンサード リンク
