This aero engine, known as the 'Spey', was built in 1963 by Rolls-Royce of Derby in England. It was used to power the Hawker Siddeley Trident 1 Airliner operated by British European Airways. The Trident was powered by three Speys, one mounted in the extreme tail, and two in pods either side of the rear fuselage.
The turbofan engine has a maximum thrust of 9850 lbs at take off, and a continuous thrust of 9450 lbs. It is fitted with a noise suppression bucket at the extreme rear of the exhaust outlet. The engine is marked 'ROLLS (RR) ROYCE, DERBY, ENGLAND, SPEY, SERIAL NO. 1032, MARK 505-5F.'
As with this engine, Rolls Royce generally named their post-war engines after British rivers. The Spey is based on the earlier 'Conway' turbofan, the world's first production engine of this type.
