Beardmore 160 hp



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.

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 and had a unit cost of £1,045. A total of 2556 were built.

A Beardmore 160 hp has been restored to airworthy condition by The Vintage Aviator Ltd, an aircraft restoration company based in Wellington, New Zealand. The engine was found complete and in a preserved condition in a farm shed in Uruguay, after a complete overhaul and ground test runs the engine powered the company's F.E.2b replica on its maiden flight.
