Turbofan Mounted On 747-100 Testbed
The new GEnx-2B jet engine for Boeing's new 747-8 aircraft has
begun flight-testing on GE Aviation's 747 flying test-bed.
During the five-hour first flight Monday, a single GEnx-2B
engine demonstrated aircraft systems and instrumentation
functionality, climbing close to 40,000 feet and establishing
engine performance baseline. About 40 flights with the engine are
planned for this spring and summer.
The GEnx-2B, slated for certification this year, is the engine
for the new Boeing 747-8. It is being flight-tested on GE's flying
test laboratory, a modernized 747-100. That aircraft was the 16th
plane off the original Boeing 747 production line, and originally
entered revenue service for Pan Am in 1972.
"GE is thrilled to power Boeing's new 747-8, which will bring a
new level of economics to commercial travel," said Tom Brisken,
general manager of the GEnx program. "It's a busy year for the
GEnx-2B with an aggressive flight-test program on GE's 747 before
it ultimately powers the new Boeing jet."
"We are excited to see the GEnx-2B successfully complete its
first flight," said Mo Yahyavi, vice president and general manager
for the 747 Program. "This is yet another step toward bringing the
747-8 to market and providing our customers with an airplane that
delivers the capabilities needed to be successful in today's
competitive environment."
