The Trent XWB is the world's most efficient aero engine flying today
Explore key technologies
The fan diameter is 118 inches. The wide-chord fan blades are the lightest and strongest fan blades in the world and are able to withstand a multiple bird strike.
Our ultra-efficient swept fan enables quieter operation and optimum core engine protection
Optimised Bearing Load Management System reduces sealing air requirements to deliver improved performance
Advanced compressor aerodynamics delivering module weight savings of 15 per cent through blisk technology
Single skin combustion casing reduces engine weight and simplifies engine maintenance
2 stage IP turbine delivers improved efficiency, greater thrust capability and a reduction in fuel burn
The HP Turbine rotor consists of 68 blades and rotates at 12,000rpm, generating centrifugal loads of up to 10 tons on each blade; equivalent to the weight of a London bus. The HP Turbine generates over 50,000 horsepower which amounts to 800 horsepower per blade - equivalent to a Formula 1 racing car.
Combustion temperatures exceed the melting point of the combustion chamber material. Cooling air is used together with ceramic coatings to enable the material to perform in these extreme environments.

Most efficient widebody engine
The Trent XWB has a 10 per cent fuel burn advantage over it’s competitors.This can save our customers around US$2.6 million per aircraft per year in fuel costs alone. This has been achieved through extensive demonstrator programmes delivering significant improvements in compressor and turbine efficiency.
- Includes the latest technology for minimised operating costs
- Has single engine type operational benefits
- Will have the lowest carbon emissions of any widebody engine
The Trent XWB combines innovative proven Trent design with world-class after-sales services delivering the best power solution for the latest aircraft family from Airbus.
It joins the Trent family of engines - the customers' number one choice, having already won nearly half of the engine orders for new generation wide bodied aircraft.
Powering the A350-800 and -900 in the 250-300 seat market, the Trent XWB continues the successful partnership of Rolls-Royce and Airbus, building on the market leading position of the Trent 700 on the Airbus A330.
The Trent XWB will also power the larger A350-1000 in the 350 seat market, the A350-900 freighter and the ultra long range A350-900R, providing a single engine type across the aircraft family.
The Trent XWB will set new standards in world-class reliability and durability through:
- Low risk engine design
- Combined experience from the engine development programmes of the Trent 900, Trent 1000 and the Trent XWB
Taking the lead
The Trent XWB will maintain the Trent's number one market position:
- Through our unique ability to offer industry leading technology at the lowest risk
- Through our focus on minimising airline costs throughout the total product life-cycle
- Through our ability to offer a single engine type for all thrust requirements
- Through our innovative technical and business solutions maximising customer value
- By setting the standard for predictability in airline operations
Overall commitments for the aircraft total more than 592 with 34 customers. With spares, this will mean a requirement for more than 1100 engines. Firm aircraft orders include customers such as Emirates (70), Qatar (80), Cathay Pacific (46) and Singapore Airlines (40).
The engine is…
- the newest member of the acclaimed Trent® family, the number one engine in the widebody market
- a unique lightweight three-shaft design that provides a tailored solution optimised for the A350 XWB
- a proven design with 65 million hours of Trent experience by the time the aircraft enters service in 2014
The engine will deliver…
- module weight savings of 15 per cent and aerodynamic efficiency improvements via the use of compressor blisk technology
- an optimised internal air system which reduces core air demand and reduces fuel burn
- higher operating temperatures improve fuel burn. Latest generation material technologies so improvement achieved without degrading reliability
- a combustor with proven reliability and that is cleaner than all current and future emissions targets
- world-beating levels of performance and noise with reduced operational cost thanks to the latest fan system technologies
- the highest efficiency turbine system of any Trent engine, which includes a second stage of IP turbine for improved efficiency and greater capability
- new bearing system, using larger bearings with increased load capability bringing fuel burn benefits
- most advanced engine health monitoring system for minimised operational disruption
The Trent XWB will be created by using advanced manufacturing techniques to develop a lighter, more capable and efficient engine to meet tomorrow’s operational needs.
Intelligent innovation means…
- maximised revenue earning potential for operators
- life-cycle cost focus has been at the heart of all design ensuring the best for engine and aircraft performance
- proven design with 65 million hours of Trent experience by the time the aircraft enters service in 2014
