Made in Scotland, United Kingdom, Europe, 1918.

This is a rare 500 hp, V12, World War I aero engine, known as a Galloway Atlantic, made in Scotland in 1918 by the Galloway Engineering Co Ltd at Tongland, Kirkcudbrightshire, (now Dumfries). As World War I progressed the demands for aircraft engines changed from small engines used in spotter aircraft to larger engines powering planes such as the Hadley Page and Vickers bombers. Increased power of 500 hp was achieved by the introduction of the V12 engine which combined two, six cylinder engines....

Object Statement

Aircraft engine, Galloway Atlantic V12, 500 hp, WWI aero engine, serial number 163, RAF serial number 46262, water cooled, 12 cylinders, made by Galloway Engineering Co Ltd, Tongland, Kirkcudbrightshire, Scotland, 1918

Physical Description

Aircraft engine, Galloway Atlantic V12, 500 hp, WWI aero engine, serial number 163, RAF serial number 46262, water cooled, 12 cylinders, made by Galloway Engineering Co Ltd, Tongland, Kirkcudbrightshire, Scotland, 1918

The Galloway Atlantic engine is a combination of two Beardmore-Halford-Pullinger (BHP) Adriatic engines. The Adriatic was a six cylinder upright in-line engine, water cooled with poppet valves. The Atlantic engine is consequently a twelve cylinder upright 60 degree Vee engine. One of the cylinders has been partly sectioned to show the valve rockers and associated gear. In a smaller Beardmore engine built to the Austro-Daimler design, the crankshaft was offset to the centre lines of the cylinders to reduce the side thrust between piston and cylinder rod which would otherwise occur during the power stroke with a shorter connecting rod. This configuration was probably adopted for this engine as well. The engine operated on the four stroke cycle and used two Claudel Hobson (HC7 Mark II) carburettors and two BTH magnetos. The engine has a No A510 Lucas 12V aero engine electric starter.
