Bristol Siddeley Gnome H.1000
Anni '60



The Gnome is a turboshaft engine with a free power turbine, that was strictly derived from the General Electric T58 engine, whose de Havilland acquired the production license in the late 1950s. The Gnome production, as well as its development program, was maintained when de Havilland was acquired by Bristol Siddeley and, later, when the latter was in turn acquired by Rolls-Royce. The Gnome engine was made in two versions: the turboshaft model, named H-series, specifically designed for helicopters, and the turboprop model, P-series, used for airplanes. Both were produced in various subtypes, both for military and civil applications. The Gnome engine was one of the first jet engines to be equipped with an (analogue) electronic control system of the fuel feed to simplify the engine load management by the pilot, while at the same time increasing the safety against accidental overloads. This system was designed specifically for the Gnome engine in Great Britain in collaboration with Lucas company and it can be considered as the forerunner of all subsequent FADEC (Full Authority Digital Engine Control) systems.
