FAA Signs Off On Second Dreamliner Powerplant
The GEnx-1B engine for the Boeing
787 Dreamliner received airworthiness engine certification this
week from the US Federal Aviation Administration.
The FAR (Federal Aviation Regulation) 33 certification follows
an extensive two-year ground- and flight-test program that involved
eight engines and two flight-test programs on GE's 747 flying test
bed. During its development and certification program, the GEnx ran
4,800 cycles and more than 3,600 hours.
"The ground- and flight-tests validated that the GEnx-1B engine
will have the lowest fuel consumption and be the most
environmentally responsible solution for Boeing 787 operators,"
said Tom Brisken, general manager of the GEnx program. "We are
extremely proud of the engine's performance, and today's
achievement is a great testament to our engineers and the entire GE
team who have worked on the GEnx engine."
First announced in 2004, called the GEnx is derived from the
ultra-high-thrust GE90 engine. GEnx-specific technologies include
composite fan blades, the highest pressure-ratio compressor in
aviation, and a unique single-annular combustor where compressed
air and fuel are mixed) to achieve dramatically lower
The GEnx is one of two powerplants approved for use on the 787.
