Trent 900

The Trent 900 is the engine of choice for the Airbus A380, with two thirds of operators selecting the engine.  It delivers the lowest lifetime fuel burn and has excellent environmental attributes.  The Trent 900 will continue to deliver customer benefits as it is part of a living engine family.

The Trent 900 demonstrates the result of the environment being the driving force behind its design.  It satisfied all its key requirements, most delivering better than specification: fuel burn, noise, emissions, weight and power.  The Trent 900 powered A380 is quiet, meeting the QC0.5 level for Arrivals and QC2 for departures. 

As the fourth generation of the Trent family of engines, the Trent 900 benefits from our ability to feed back low-risk new technology from future generations.  Rolls-Royce has a demonstrated commitment to continuous improvement, having already delivered a fuel burn improvement package for the Trent 900.  Further enhancement is planned to make the Trent 900 up to 1.8% better than specification.

The excellent environmental attributes of the engine are evident as it has the greatest cumulative margin to ICAO emission standards of any engine for the A380.  The engine has the lowest NOx emissions for the A380, NOx is currently the only regulated emission subject to specific airport charging.

The Trent 900 is certified at 70k, 72k, 76k and 80k pounds of thrust.  It is the only engine certified at both 70k and 72k for the Airbus A380. The higher two ratings demonstrate the growth capability embedded in the engine, should further aircraft development be required.

Leading technology
High technology, great benefits

The Trent 900 is the fourth member of the Trent family and includes the latest proven technology. For example:

• The engine’s 24 fan blades are to a new swept design that reduces the effect of shock waves, as the tip of the fan rotates supersonically, making it lighter, quieter and more efficient.
• The fan containment system is also the first to be manufactured from Titanium and does not need the additional Kevlar wrap, making it a lighter and smaller system.
• At the core of the engine, the high-pressure shaft rotates in the opposite direction to the other two shafts, meaning the engine can be made lighter and more fuel-efficient.

Designed for service

• Low cost of ownership.
• The only engine for the A380 that can be transported whole in a Boeing 747F.
• Designed for ease of maintainability with fancase mounted units.
• Core scaled from the Trent 500.
• Benefits of Trent family experience.

Excellent fuel efficiency

• Delivers the lowest lifetime fuel burn for the A380.
• Continuous improvement is soon to deliver an engine up to 1.8% better than specification.
• Three-shaft design delivers excellent performance retention.

Best for the environment

• Quiet: meets stringent London noise requirements of QC2 for departure and QC0.5 for arrival.
• Lowest emissions on the A380.

Capable engine

• The only engine certified to both 70k and 72k pounds of thrust on the A380.
• Engine certified to 80k pounds of thrust.
• A single bill-of-materials, with thrust growth capability.
