Improving fuel efficiency
Improving fuel efficiency is critical to our customers, both to reduce costs and to improve their environmental performance. We are meeting this need by continuously introducing innovative technologies into our Trent engine family. Our latest engines deliver significant efficiency improvements compared to their predecessors. The Trent 1000, which first entered service in 2011, is 12 per cent more fuel-efficient than the Trent 800, which entered service in 1996. Looking ahead, the Trent XWB, due to first power an Airbus A350 XWB in 2013, will provide an improvement in fuel efficiency of more than 15 per cent compared to the Trent 700, which entered service in 1995.
In 2012 we unveiled our Trent 1000-TEN (Thrust, Efficiency and New technology). This incorporates proven next generation technology from the latest member of the Trent engine family, the Trent XWB, to produce the ideal engine for the entire Boeing 787 Dreamliner family. The Trent 1000-TEN will provide an improvement of up to three per cent in specific fuel consumption compared with the current Trent 1000 standard.
The Gulfstream G650 powered by our BR725 engines entered into service in December 2012. The BR725 is the latest and most advanced member of the BR700 engine series. It demonstrates a four per cent improvement in specific fuel consumption and a 21 per cent reduction in NOx emissions, compared to its predecessor the BR710.
The Series 3.5 Engine Enhancement for the T56 turboprop engine, which powers the C-130H transport aircraft, is designed to deliver fuel savings and reliability improvements, improving life cycle costs. It has demonstrated a 9.7 per cent fuel burn improvement in ground tests, using proven technologies from other Rolls-Royce commercial and military engines, including new blade and vane materials and advanced turbine airfoil aerodynamic designs.
We recognise that management of fuel usage is of paramount importance. As such, we evaluate all opportunities to conserve fuel. Our wholly-owned subsidiary OSyS helps customers to reduce fuel usage, to mitigate environmental impact and to implement emissions monitoring, reporting and verification (MRV) to meet emissions trading scheme (ETS) requirements. These services could save customers as much as one to three per cent of their total fuel bill without compromising their operational capability.
