Beardmore Halford Pullinger

From Wikipedia, the free encyclopedia

Beardmore-Halford-Pullinger (BHP) were a series of aircraft engines produced between 1916 and 1918.[1] The engines were used on many First World War aircraft, including the Airco DH.4 and DH.9.[2]

Formation

The name B.H.P is derived from surnames of three people:[3]

230 hp BHP engine

Beardmore started building aero-engines in 1913 when the group acquired the rights for licensed production of the Austro-Daimler 6. Arrol-Johnson (a Beardmore subsidiary involved in automobile production) produced the Austro-Daimler 90 and 120 hp engines at their facility in Dumfries, Scotland. The 120 hp engine was further developed at the Arrol-Johnson works with inputs from Frank Halford who was assigned to the firm as a liaison officer. Changes included the introduction of twin carburetors and dual ignition. The resulting engine was sold as the Beardmore 160 hp.[6]

Halford and Pullinger then designed a completely new engine. A new company, the Galloway Engineering Co. Ltd. was set up in Kirkcudbright, near Dumfries, to continue development and production of the engine. It was developed and marketed as the Galloway Adriatic.[5][6]

The 230 hp engine was also licensed to Siddeley-Deasy, to be built at their Parkside works. John Siddeley himself worked on the engine and, after making many changes, released the engine as the Siddeley Puma. The Puma was later developed into the ADC Nimbus.[6]

In British military service both Siddeley and Galloway built engines were known as the 230 hp BHP although they had different dimensions and few interchangeable parts.[6][7]

Far more Siddeley Pumas were produced than Galloway Adriatics. At the end of WW1, the RAF had 89 Adriatic and 3,255 Puma engines in service. All of the Adriatic engines were fitted to aircraft based in the United Kingdom.[8]

V12 derivatives

  • Galloway Atlantic. Two cylinder blocks from the Galloway Adriatic combined on a single crank shaft to create the V12 configuration Atlantic, delivering 500 hp.
  • Siddeley Pacific. Two cylinder blocks from the Siddeley Puma combined on a single crank shaft to create the V12 configuration Pacific, delivering 500 hp.[6]
