The Salmson B.9 was a French designed, nine-cylinder, water-cooled radial aero engine that was produced under license in Britain. The engine was produced between August 1914 and December 1918. The French version was designated 9B with a slightly increased capacity variant known as the R.9 or 9R.[1] A further variant known as the M.9 or 9M unusually drove the propeller through a 90-degree gear train.[2]
