Rolls Royce achieves 10 million engine flight hours on the Trent XWB

LONDON – Rolls Royce today announced that the Trent XWB-84, which powers the Airbus A350-900, has achieved 10 million engine flight hours.

The XWB-84 entered service in 2015 and powers more than 30 A350-900 operators, operating on a variety of flights from short-haul to ultra-long-haul.

Cholerton: a great success…


Chris Cholerton, President of Rolls-Royce Civil Aerospace, said:

“Achieving 10 million flight hours is another great achievement for the Trent XWB. It is the last engine in the Trent family to reach this milestone and it has done so faster than any other Trent engine in just over seven years of operation.

“We are incredibly proud of the Trent XWB as it continues to set new benchmarks for durability, reliability and versatility.”

An impressive engine…


The Trent XWB is the world’s most efficient in-service aircraft engine and supports airlines in their sustainability journey.

The engine has a 15% fuel economy advantage over the first Trent engine, burns less fuel and delivers industry-leading performance and noise levels. It is also ready to run on 50% sustainable aviation fuel as they become more available to airlines in the future.

Additionally, the Trent XWB-84 has helped avoid more than 15 million tonnes of CO2 since its launch in 2015 – that’s the same amount of CO2 it takes to power nearly two million homes each year.

On top of that, the Trent XWB-84 has consistently offered a 99.9% dispatch reliability rating since the engine also entered service.

Achieving this level of consistency in dispatch reliability is a testament to the quality that has been given to A350-based propulsion, and this figure is expected to remain the same for years to come.

The XWB legacy will continue…


It is clear that the XWB-97, which powers the A350-1000 variant, will not be far from reaching this figure, as it will probably be in the next few years.

Based on information as of July 31, 2022, 491 Airbus A350s have been delivered to their respective customers, with Rolls Royce powering the -900 and -1000 variants.

There are still 447 A350s to be delivered, with that number increasing from time to time with orders from potential past and future air shows.

As for the A350 Freighter, there are currently 31 on order at the time of writing, with Rolls Royce also powering this aircraft type when it enters revenue service in the next few years.

Globally…


It remains clear that the Trent XWB is delivering impressive results for Airbus A350 operators. As the XWB-84 continues on its high reliability path, it won’t be far off until the XWB-97 produces the same results.

Going forward, Rolls Royce will look to continue this long streak of positive results, especially as the A350 is one of the latest next-generation technologies for long-haul travel.

The next test will take place before Project Sunrise, where we can see in more detail how well the engine’s performance holds up to 19-20 hour flights.
