The Rolls-Royce RB.183 Tay is a medium-bypass turbofan engine, developed from the RB.183 Mk 555 Spey core and using a fan scaled directly from the Rolls-Royce RB.211-535E4 to produce versions with a bypass ratio of 3.1:1 or greater. The IP compressor and LP turbine were designed using technology from the RB.211 programme.[1] The engine was first run in August 1984.[2] The Tay 650 had a new HP turbine which incorporated new technology which had been proven with the RB.211-535E4. This engine also had a new combustor for improved durability.[3] The Tay family is used on a number of airliners and larger business jets, including the Gulfstream IV family, Fokker 70 and Fokker 100, with a later version being used to re-engine Boeing 727-100s.
Variants
Tay 611-8
Originally designated 610-8, all but one training engine have now been converted to 611-8 standard. The newest variant is the 611-8C, which has cast HP1 turbine blades, larger fan from the 650-15, structural by-pass duct and FADEC.
All Tay engines use a 22-blade titanium fan, a 3-stage intermediate-pressure compressor coupled to the fan shaft, a 12-stage high-pressure compressor, a 2-stage high-pressure turbine and a 3-stage low-pressure turbine.
Thrust: 13,850
Tay 620-15
The 620-15 is internally identical to the 611-8 and externally similar to the 650-15.
Thrust: 13,850
Tay 650-15
Thrust: 15,100
Tay 651-54
The 651-54 is internally identical to the 650-15. The externals and gearbox suit the Boeing 727.[4]
Thrust: 15,400
