General Electric (GE) within weeks
expects to receive certification for the baseline GEnx engine that will power the
delayed Boeing 787 twinjet.
Documentation to the US FAA is being
processed and certification will occur “sometime by the end of this quarter”,
said GE Aviation president and CEO Scott Donnelly today at the JP Morgan
Aviation and Transportation Conference in New
GE is developing two versions of the
GEnx, the -1B powering the 787 and the -2B for the
747-8. Delays to the 787 have given both GE and rival supplier Rolls-Royce more
time to mature their engines before entry into service.
This extra time is facilitating an
improvement program for the -1B; these improvements are now being tested on the
While GE is “obviously a little bit
disappointed to see the slide in the 787” schedule, says Donnelly, the GEnx engine “will be ready to go” when Boeing is ready. The
airframer has said it will release its new 787
schedule by the end of this quarter.
GE, meanwhile, achieved “a
significant milestone” in the GEnx-2B program when, during ground testing last
week at GE’s outdoor testing facility in Peebles,
engine demonstrated 70,950lb of takeoff thrust.
“The initial results of the ground
tests are extremely positive, and we look forward to preparing the engine for
flight tests on GE’s flying test bed later this year,” said Tom Brisken, general manager of the GEnx
program, in a statement.
The certification program for the
GEnx-2B engine will involve five engines. Engine certification is anticipated
in first half of 2009 with entry into service in late 2009.
