TheRolls-Royce RB.109 Tyne is a twin-shaftturboprop engine developed in the mid to late 1950s byRolls-Royce Limited to a requirement for theVickers Vanguard airliner. It was first test flown during 1956 in the nose of a modifiedAvro Lincoln.[1] Following company naming convention forgas turbine engines this turboprop design was named after theRiver Tyne.
Designed in 1954 by a team under Lionel Haworth and intended as a more powerful alternative to theDart, the RB.109 Tyne was initially designed for a power of 2,500 shp but when first run in April 1955 the engine far exceeded expectations and was soon beingtype-tested at 4,220 shp.[2] The Tyne was developed primarily for the four-enginedVickers Vanguard airliner, the prototype first flying on 20 January 1959 equipped with four Tyne Mk.506 of 4,985 e.s.h.p.[3] Production deliveries of the engine were made from mid-1959 onwards to power the 43 Vanguards delivered toBritish European Airways andTrans-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 theCanadair CL-44 andTransall C-160 transport aircraft.
A single stage HP turbine drives the nine-stage HP compressor. A three-stage LP turbine drives the six-stage LP compressor and, through a reduction gearbox, the propeller. Thecombustor iscannular.
The Mark 515 Tyne had a nominal takeoff power output of 5,730 hp (4,273 kW) equivalent power, flat rated to ISA+16.8C.
An agreement was signed in 1963 betweenHispano-Suiza and Rolls-Royce for the licence production of the Tyne for theBreguet Atlantic andTransall C-160.[4] Each company that was part of the agreement built parts for itself and the partners, Rolls-Royce (United Kingdom) 20%, Hispano-Suiza (France) 44%, MAN (Germany) 28% and FN (Belgium) 8%.[4] The final assembly was undertaken by both MAN and Hispano-Suiza.[4] The first production batch was for 80 engines and 40 spares for the Atlantic.[4]
The marine version, the Rolls-Royce Tyne RM1A, RM1C and RM3C remained in service as the cruise gas turbines in Royal NavyType 21 frigates,Type 42 destroyers andType 22 frigates until the retirement of the 4 Batch 3 Type 22 frigates (2011) and the last remaining Type 42 Destroyer (2013). They were also used in numerous other European ships such as theTromp andKortenaer-class frigates.[6]
A Rolls-Royce Tyne is on public display at theRoyal Air Force Museum Cosford.[citation needed]
