The Sapphire engine is a turbojet with an axial-flow compressor and an annular combustion chamber of the Armstrong Siddeley vaporising type. It was the first British turbojet to be type-tested at over 4450kg (10000lb) static thrust. This engine was used to power the RAF’s Javelin, Hunter and Victor aircraft and was also used on the English Electric P1A.
