The Beardmore 160 hp is a British six-cylinder, water-cooled aero engine that first ran in 1916. It was built by Arrol-Johnston and Crossley Motors for William Beardmore and Company as a development of the Beardmore 120 hp, itself a licensed-built version of the Austro-Daimler 6.[1]
Development
[edit]The engine featured cast iron cylinders and mild steel concave pistons. Produced between March 1916 and December 1918, the design powered many World War I aircraft types. It was noted that the engine was not as reliable as its smaller capacity predecessor.[2]
