Introduction

The Rolls Royce Trent is the development of the three-shaft RB211 family of engine. By 1987 the variant of the RB211 , the RB211-524L , had been developed to such an extent that it bore little resemblance to the original RB211, other than the three-shaft layout. Rolls-Royce decided that the -524L shall be a basis of a new engine family, hence the Rolls Royce Trent was born.

The Trent's advanced layout provides lighter weight and better performance compared to the original RB211 and other comparable competing engines. It features the wide-chord fan , single crystal high-pressure turbine blades inherited from later generations of RB211 but with improved performance and durabilty.

Its core turbomachinery is brand new, giving better performance , noise and pollution levels. So good that it is retrofitted back to the RB211-524G/HT for better performace as compared to the original -524G and -524H. The Trent's advanced layout allows it to be fully scalable to the widest range of thrust of any current generation big turbofans.

Variants

Trent 500 Series

The Trent 500 family is designed to power the Airbus A340-500 and A340-600. It comes in 2 thrust ratings, 53,000 and 56,000 lb (236 to 249 kN) thrust. The Trent 500 features a Trent 700 wide-chord fan together with a core scaled from the Trent 800.

Trent 600 Series

Trent 700 Series

The Trent 700 family is designed to power the Airbus A330. It powers all variant of the A330. It features a fan with a diameter of 2.47 m. It comes in 2 thrust ratings, 67,500 and 71,000 lb (300 to 316 kN) thrust. It entered service on Cathay Pacific A330 aircraft in March 1995.

Trent 800 Series

The Trent 800 family is designed to power the Boeing 777. It powers all variants of 777 except -200LR and -300ER.It comes with thrust ratings spanning from 75,000 to 95,000 lb (334 to 423 kN) thrust.

It features 2.89 m diameter fan. With its three-shaft configuration and hollow titanium wide-chord fan makes a Trent-powered Boeing 777 weigh up to 3.6 metric tons less than GE and Pratt & Whitney powered versions. It is the most popular 777 engine with 44% market share.

Trent 8104

Originally designed for 777-200LR/-300ER, it comes in 2 thrust ratings 104,000 and 114,000 lb (463 to 507 kN) thrust and has been tested up to 117,000 lb (520 kN) thrust.

Rolls-Royce offered the 8104 to Boeing earlier than other manufacturers. However as Boeing decided to power the 777-200LR/-300ER exclusively by General Electric GE90, the 8104 is now a demonstrator engine. It featured swept-back fan blades and a host of new technologies.
