Developed from Galloway Adriatic

The Galloway Atlantic is a 500 hp V12 aircraft engine that was ordered into production toward the end of World War I. It was developed as a V12 configuration of the inline-six Galloway Adriatic, with two Adriatic cylinder banks mounted on a single crankcase.

Contents

The Atlantic saw postwar service in Handley Page V/1500 bombers built by Galloway’s parent company, William Beardmore & Co. In contemporary publications the type was often referred to as the Beardmore, or BHP , Atlantic or 500 hp.

In the United States, Galloway Atlantic engines were fitted to the Remington Burnelli RB-2, which was, at the time, the world’s largest commercial freight aircraft. These engines were also a popular choice for smugglers operating fast boats during the prohibition era.

Design and development

The Galloway Atlantic is essentially a double form of the Galloway Adriatic with two banks of six cylinders set at 60 degrees working a single crankshaft. The articulated master-and-slave connecting rods allows corresponding cylinders in each row to be arranged directly opposite each other but gives the 6-cylinder bank with the articulated rods a longer stroke than the opposing bank. [1] [2]

The cylinders on the Atlantic are made of cast iron in blocks of three. Cast iron cylinder blocks had previously been tried on some Adriatic engines due to the difficulties of casting and machining aluminum. [3]

800 engines were ordered from Beardmore’s subsidiary companies; Arrol-Johnston and Galloway Engineering. Most were cancelled when WW1 ended. Only 72 engines were completed all of these being built at Galloway's factory in Kirkcudbright near Dumfries, Scotland. [2] Marketing for the engine was inconsistent with the type variously referred to as the Galloway, or Beardmore, or BHP, Atlantic or 500 hp. [4] [a]

Aircraft number E8287 was the first of the Beardmore built Handley Page V/1500s and was fitted with four Galloway Atlantic engines. The aircraft had been handed over to the Royal Air Force by December of 1918. The Atlantic engines can be distinguished from the Rolls Royce Eagle engines, which were also in use on the V/1500, by the absence of exhaust pipes. [5] The Atlantic was the most powerful engine fitted to the Handley Page V/1500 heavy bomber and was one of the most powerful aero-engines of its time. [2] [6]

In the United States, Galloway Atlantic engines were fitted to the Remington Burnelli RB-2 lifting body cargo aircraft. [7] These engines also powered fast motorboats operated on the Great Lakes by Chicago-based rum-runners during the prohibition era. [8]

The Atlantic was the last aircraft engine type manufactured by Galloway with the factory switching over to automobile production during the 1920s. [9]

Notes

  1. ↑ There were also double forms of the Siddeley Puma known as the Siddeley Pacific and Siddeley Tiger. The Puma and Adriatic engines were based on the same design and had a closely interlinked development and production history. [2]
