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.

Since entry into service in 1988 as the sole powerplant for the Gulfstream GIV, the Tay has established a reputation for outstanding reliability, economy, good propulsive efficiency and low noise generation and has more than 2,000 engines installed worldwide.

Rolls-Royce Tay is the name of two different jet engines: Rolls-Royce RB.44 Tay, an afterburning turbojet engine, based on the 1940s Rolls-Royce Nene; Rolls-Royce RB.183 Tay, a twin-spool high bypass turbofan engine, first run in 1984

The Rolls-Royce RB.44 Tay is a British turbojet engine of the 1940s, an enlarged version of the Rolls-Royce Nene designed at the request of Pratt & Whitney. [1] It saw no use by British production aircraft but the design was licence built by Pratt & Whitney as the J48, and by Hispano-Suiza as the Verdon. [2]

The Tay 620 and Tay 650 power the Fokker 70 and Fokker 100 aircraft - they’re go-to engines for many regional airlines and major carriers alike.

Apr 30, 1998 · There are over 1,500 Rolls-Royce Tay engines operating worldwide on Gulfstream, Fokker-100, and some Boeing 727 aircraft. There are basically four derivatives of the Tay — the 611, 620, 650,...

The Rolls royce tay is the combination of two highly successful engines. The high pressure system comes from the RB183-555 engine of the Fokker F28. The low pressure system comes from the RB211-53E4 "big fan" engine.

Oct 16, 2018 · The Rolls-Royce Tay 611-8 engine, which entered service in 1987, recently achieved another incredible milestone by reaching 10 million flying hours in nearly 5 million flights.

Sep 18, 2009 · 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.
