Boeing closes on 777X engine choice

摘要

Boeing will set out its engine strategy for its upgraded 777X twinjet in the first quarter of 2013, a major supplier says. The US airframer issued a request for proposals in late 2011 to engine manufacturers Pratt & Whitney, Rolls-Royce and General Electric to offer powerplants for the next generation of the hugely successful widebody. GE is the incumbent supplier on the current iteration of the 777. While early models of the long-haul twinjet were available with engines from all three manufacturers, all in-production aircraft - the 777-200LR and -300ER passenger jets alongside the 777 freighter - are exclusively powered by General Electric GE90-110B and -115B engines.
