Boeing and General Electric Validate 747-8 Quiet Technologies
SEATTLE, Sept. 20, 2006 -- The Boeing Company [NYSE: BA] and General Electric successfully completed airplane engine ground testing on noise-reduction improvements being incorporated into the new Boeing 747-8. The test conducted by Boeing and GE indicates the 747-8 will meet its targets for noise reduction.
An elaborate array of monitoring equipment and microphones recorded engine operating conditions and noise levels at multiple locations in and around the engine. The ground test on a GE90-115B engine conducted at GE's test facility in Peebles, Ohio, focused on noise-reduction technologies planned for incorporation into the engine case and nacelle of GE's GEnx-2B, which will power the 747-8.
