Rolls-Royce Tay (turbofan)
The Rolls-Royce RB.183 Tay is a turbofan engine, developed from the RB.163 Spey, using scaled down low-pressure components from the RB.211 to produce versions with a bypass ratio of 3.1:1 or greater. The engine was first run in August 1984.[1] The Tay family is used on a number of airliners and larger business jets, including the Gulfstream IV, 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 a modified high pressure nozzle box, cast HP1 turbine blades, larger fan from the 650-15, structural by-pass duct and FADEC.
All Tays consists of a twenty-two blade titanium fan, 3 stage Intermediate pressure compressor (Same spool as the fan.), 12 stage High pressure compressor, 2 stage high pressure turbine, 3 stage low pressure turbine.
Thrust: 13,850 lbf (62 kN) Aircraft: Tay 611 entered service in 1987 on the Gulfstream IV/IV-SP, for which it is the exclusive powerplant.
Tay 620-15
The 620-15 is internally identical to the 611-8 and externally similar to the 650-15.
Thrust: 13,850 lbf (62 kN) Aircraft: Fokker 70 from 1994, Fokker 100 from 1988
Tay 650-15
Thrust: 15,100 lbf (67 kN) Aircraft: Originally designed to re-engine the BAC One-Eleven (650-14, only two made, both have since been converted to 650-15 standard.), the 650-15 entered service on the Fokker 100 in 1989.
Tay 651-54
The 651-54 is internally identical to the 650-15. The thrust increase comes solely from an adjustment to the Fuel Flow Meter.
Thrust: 15,400 lbf (69 kN) Aircraft: Boeing 727-100 from 1992. Conversion from three JT8D-7 to three Tay 651-54 was done by the now defunct Dee Howard Aircraft Maintenance Company in San Antonio Texas for the United Parcel Service. Only one private 727 was converted, it is believed to be flying in Australia for a casino.
