That big roar you may have heard around Peebles, OH Tuesday was
the sound of progress in Boeing's quest to build the 787
General Electric Aviation says its first run-up test of the GEnx
engine came off without a hitch. The new engine generated 80,500
pounds of thrust, and was the culmination of a design and
manufacturing process that was so successful, the tests were held
three days early.
"It is exciting to see the GEnx come to life," said Tom Brisken,
general manager of the GEnx program. "Engine assembly was flawless,
and engine testing began three days ahead of schedule. We are
extremely pleased with initial test results and are looking forward
to validating the GEnx technology."
The GEnx was fired up for the first time for idle tests March
The engine's maturation
program will accumulate more than 15,000 cycles by entry into
service and 50,000 cycles total. With a range of thrust from 53,000
to 75,000 lbs, this GEnx engine will power all versions of the 787
The GEnx engine will not only power the Dreamliner. It'll also
replace GE's CF-6 engine family designed for wide-bodied aircraft
such as the Boeing 747, and will also power Airbus's A350
The GEnx is slated to go into service in 2008. Seventeen
customers have so far ordered 575 NX engines from GE.
