Salmson 9
The term Salmson 9 refers to any of a number of nine-cylinder, radial aircraft engines that were developed from 1910 onwards and built by Société des Moteurs Salmson in France. All Salmson engines produced after 1920 were air-cooled.[1]
Design and development
The designation Salmson 9 merely refers to the number of cylinders and the different series of engines were identified by the letter suffixes. Like most radials, later versions were air-cooled, but early Salmson engines were famous for being the only series-produced water-cooled radials. In common with other engines produced by this manufacturer, Salmson 9s featured the unorthodox Canton-Unné internal arrangement that dispensed with a master rod in favour of a cage of epicyclic gears driving the crankpin. Production ended in 1951 with the liquidation of the manufacturing company.
