DE HAVILLAND GOBLIN
Design of what became the de Havilland Goblin gas turbine engine was commenced by Frank Halford in April 1941 as the H-1. It was based on the design pioneered by Frank Whittle using a centrifugal compressor with a single stage power turbine. It first ran in April 1942 and first flew in a Gloster Meteor in March 1943. de Havilland had taken over Halford's company and Halford himself joined DHs and ran the de Havilland Engine Company, and the engine was re-named Goblin.
In 1943, one of the engines was sent to the USA to power the Lockheed P-80 Shooting Star. Allis Chalmers was selected to produce the engine in the US as the J36.
Five variants of the Goblin were produced with thrust ratings increasing from the 2,700lbs of the Goblin 1 through to 3,750lbs of the Goblin 4. The engine virtually remained the same as the Goblin 1 for thirteen years before it reappeared as an export variant, the Goblin 35 with a thrust rating of 3,500lbs, and which preceded the Goblin 4.
In addition to Gloster and Lockheed, Curtiss, Fiat and SAAB used the Goblin engine to power some of their products.
Further development of the Goblin evolved into the uprated de Havilland Ghost engine that later powered the de Havilland DH.106 Comet aircraft.
