摘要

JENS FLOTTAU and LEITHEN FRANCIS/SINGAPORE and GUY NORRIS/LOS ANGELES Airbus and Rolls-Royce, addressing customers' concerns about performance of the Trent XWB engine, are working on a potential thrust-margin increase of roughly 5,000 lb. that is needed for the A350-1000. The measures involve a substantial design change that could force the planned service-entry target for the larger model to slide one year to at least 2016. The plans come as key customers such as Air Lease Corp. (ALC) and Emirates have publicly voiced doubts that the engine as now defined may not be powerful enough. Industry sources say Airbus and Rolls-Royce will announce a more powerful engine at the Paris air show this month. The engine will feature changes to the core and fan, as well as other modifications, to deliver the needed additional margins, officials point out.
