Rolls-Royce Tyne
The Rolls-Royce RB.109 Tyne is a twin-shaft turboprop engine developed in the mid to late 1950s by Rolls-Royce Limited. It was first test flown during 1956 in the nose of a modified Avro Lincoln.[1]

Design and development
The Tyne was developed primarily for the four-engined Vickers Vanguard airliner, the prototype first flying on 20 January 1959 equipped with four Tyne Mk.506 of 4,985 e.s.h.p.[2] Production deliveries of the engine were made from mid 1959 onwards to power the 43 Vanguards delivered to British European Airways and Trans-Canada Airlines.
The engine was further developed with greater power and used in the later twin-engined Dassault-Breguet Atlantique long-range reconnaissance aircraft; also in the Canadair CL-44 and Transport Allianz Transall transport aircraft.
A single stage HP turbine drove the 9 stage HP compressor, whilst a 3 stage LP turbine drove, not only the propeller (via a reduction gearbox), but a 6 stage LP compressor. The combustor was cannular.
So the Tyne, like the ill-fated Bristol Orion, has a shared-load LP turbine, as opposed to a free power turbine, as used in the Bristol Proteus and most modern turboprop engines.
The Mark 515 Tyne had a nominal takeoff power output of 5,730 shp, flat rated to ISA+16.8C.

Maritime use
The marine version, the Rolls-Royce Tyne RM1A, RM1C and RM3C are still in service as the cruise gas turbines in Royal Navy Type 42 destroyers and Type 22 frigates.
Current use
Many aero engines remain in service in Transalls with the French, German and Turkish airforces and will do so until 2015. Similarly marine versions remain in service and will do so until at least 2014.
