Rolls-Royce has introduced the first of a two-phase performance improvement for the Trent 900 engines that power the Airbus A380 airliner. Turbofans now being delivered to A380 operators have a one-percent improvement in specific fuel consumption compared with the initial units.
Rolls-Royce has won an order from Saudi Arabian Airlines to provide Trent 700 engines and TotalCare support for four Airbus A330s that the Middle Eastern carrier has on order. It also covers four options, should they be exercised. The deal could be worth up to $500 million.
The announcement of the new joint venture between Rolls-Royce and Pratt & Whitney was hardly a statement of marriage, but the vows made by the two aero-engine giants on October 12 nevertheless marked the securing of their long-term future in the huge market for mid-sized aero-engines up to 2030.
All appears forgiven between Rolls-Royce and Pratt & Whitney now that the two engine manufacturers prepare to collaborate on the next generation of turbofans for midsize airliners ranging in size from 120 to 230 seats.
Thermal processing specialist Bodycote has signed a 10-year renewal contract with Rolls-Royce to provide its services in the UK and potentially other parts of the world, including North America and Asia.
Rolls-Royce believes it can contain the financial cost of last November’s uncontained disc failure in a Trent 900 engine to not much more than £56 million ($89.6 million). It allocated that amount for dealing with the fallout from the accident on a Qantas A380 airliner in its financial results for 2010, announced on February 10.
The Australian Transport Safety Bureau confirmed the potential existence of a manufacturing problem in Rolls-Royce Trent 900s fitted to some Airbus A380s in a safety recommendation it issued today. The recommendation identifies a potential defect in an oil tube connection to the high-pressure (HP)/intermediate-pressure (IP) bearing structure.
Pratt & Whitney today filed a complaint in the U.S. District Court in Connecticut against Rolls-Royce, claiming that UK-based engine maker misled the U.S. Patent & Trademark Office to obtain a patent related to swept fan blades.
U.S. energy group Solena is accelerating its efforts to establish a plant in the London area that from 2014 could be turning 500,000 metric tons of domestic waste into jet fuel each year. Its GreenSky program has already attracted its first customer in British Airways, which has committed to buying the new factory’s complete annual output as part of its goal to halve its total carbon dioxide emissions by 2050.
Rolls-Royce today filed a complaint alleging infringement by United Technologies Corp. (UTC) of the Rolls-Royce swept fan blade patent. The complaint specifically identifies the fan stages on both the Engine Alliance GP7200 engine and the Pratt & Whitney PW1000G engine. It also alleges that a number of other UTC aerospace civil engines infringe the Rolls-Royce patent.
