A versatile engine powering both military and civil aircraft types.
The latest of the Spey family is the Spey 807, a two shaft turbofan with a four-stage low pressure (LP) and 12-stage high pressure (HP) compressor driven by a two-stage LP and two-stage HP turbine respectively. The combustor is of cannular design with 10 liners, as all other Spey variants.
This engine first entered service more than 30 years ago and is used by military and civil customers around the world. The military Spey was developed to meet the needs of high performance aircraft in both subsonic and, with reheat, supersonic operations.
The Spey 807 for the single-engined AMX strike aircraft is in service in Italy and Brazil. Other Spey variants such as the Spey 250 power the BAE SYSTEMS Nimrod MR2patrol aircraft. In addition, the Spey powers the military versions of Gulfstream GII and GIII aircraft in service in VIP transport and reconnaissance roles with a number of armed forces around the world.
Besides military power, the Spey also provides power for civil applications of the Gulfstream GII and GIII executive aircraft, although the civil version is no longer in production. Other aircraft powered by the Spey include the BAC 1-11 and Fokker F28. The Spey entered service in 1968 and 2,768 civil and military engines were built, achieving over 50 million hours in service to date.
