Trent XWB-84 Enhanced Performance | Rolls-Royce

The Rolls-Royce Trent family of engines, a significant player in the modern turbofan market, has seen numerous variants developed over the years. Among these is the Trent XWB, specifically designed for the Airbus A350 aircraft. The British engine manufacturer recently announced an upgrade package for one of its most important models, the XWB-84.

In a statement released by Rolls-Royce, the company introduced the Trent XWB-84 Enhanced Performance (EP) package. "The best widebody engine just got better," according to Rolls-Royce. This upgrade includes technological advancements aimed at improving reliability and efficiency while reducing environmental impact.

"Our latest suite of cutting-edge enhancements strengthens the Trent XWB’s industry-leading reliability while delivering even greater fuel efficiency and lower environmental impact," said Rolls-Royce. The EP package enables at least a 1% reduction in fuel consumption, leading to annual fleet fuel savings of $5 million. These improvements result in lower CO₂ emissions and quieter operations by up to two decibels without compromising durability.

Rolls-Royce emphasized that this development marks "a new era of efficiency, sustainability and profitability for our airline customers." The Airbus A350, powered by Trent XWB engines, is used by various long-haul airlines worldwide and accumulates thousands of flight hours daily on long routes.

The company asserts that the XWB-84 "is the world’s most efficient large aero engine," providing 25% reductions in fuel burn and carbon dioxide emissions. Despite these achievements, Rolls-Royce aims to enhance further through continuous improvement efforts with Sustainable Aviation Fuel (SAF). While currently certified to operate with SAF blends up to 50%, Rolls-Royce targets full capability with 100% SAF in future operations.

Durability remains crucial for engines powering long-haul flights like those on Airbus A350 aircraft. To ensure this characteristic alongside performance improvements, Rolls-Royce subjected eight development engines and three flight test engines to extensive testing before certifying the EP package last December.
