The Rolls-Royce RB.183 Tay is a twin-spool, high bypass turbofan engine manufactured by Rolls Royce for the Fokker 70 and Fokker 100 aircraft. The RB.183 Tay consists of a twenty-two blade titanium fan, three-stage Intermediate pressure compressor, twelve-stage High pressure compressor, two-stage high pressure turbine, and three-stage low pressure turbine. This aircraft engine was 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.
