The Salmson water-cooled aero-engines, manufactured by Société des Moteurs Salmson in France between 1908 and 1920, were notable for integrating water-cooling with a radial cylinder configuration.

History

Henri Salmson, originally a producer of water pumps, collaborated with Swiss engineers Georges Marius Henri-Georges Canton and Pierre Unné to develop their engine concepts. Early axial barrel engine models were unsuccessful due to poor reliability and excessive fuel use. Following this, Canton and Unné designed a 7-cylinder water-cooled radial engine, which was later enlarged to include 9-cylinder versions and two-row configurations with 14 and 18 cylinders. By 1912, the Salmson A9 generated approximately 120 bhp, matching the performance of contemporary French competitors. As rivals emphasized lower power outputs, Salmson pursued development of higher-powered engines.

Production occurred at the Billancourt plant owned by Salmson, which expanded during World War I, alongside the establishment of a second factory in Villeurbanne. The Salmson-Canton-Unné engine series was also produced under license in Russia and Great Britain at the Dudbridge Iron Works in Stroud between 1914 and 1918.

Applications

Aircraft equipped with Salmson water-cooled engines included:

Salmson 9A
Salmson 9B
Salmson 9C
Salmson 9M
Salmson 9P
Salmson 9R
Salmson 9Z
Salmson 2M7
Salmson 18Cm

Variants and specifications

Certain references identify the radial models as Salmson (Canton-Unne), named after the Swiss engineers who commissioned Salmson to manufacture engines derived from their designs.
