GE Aviation Receives Award for FAA CLEEN Research
EVENDALE, OH – June 24, 2010 — GE Aviation received an award from the
Federal Aviation Administration (FAA) as part of the Continuous Lower
Energy, Emissions and Noise (CLEEN) program. CLEEN is an FAA program to
accelerate the development and maturation of aircraft and engine
technologies that reduce noise and emissions and improve fuel burn. The
program goal is to enable the new technologies to enter the fleet
beginning in 2015. GE and the FAA will share the investment of up to $66
million for up to a five-year period.

The CLEEN award will help fund three GE technologies, including TAPS II
Combustor, Open Rotor and Flight Management System – Air Traffic
Management (FMS-ATM).

“GE has always invested in advanced technologies to lower fuel burn,
emissions and noise,” said Dale Carlson, Advanced Engine Systems for GE
Aviation. “This CLEEN award will allow us to quicken our pace on
research on key technologies that will provide our customers with more
fuel efficient technologies to help reduce their costs and their impact
on the environment.”

The three GE technologies being funded are:

*    TAPS II Combustor: GE is developing the TAPS II combustor for
its new engine core, called eCore. eCore will be part of CFM
International’s* new LEAP-X engine for narrowbody aircraft as well as
the new core for GE’s next generation regional and business jet engines.
The new core will offer up to 16 percent better fuel efficiency than
GE’s best engines in service today. GE began testing the TAPS II
combustor in June 2009 at a special altitude test chamber in Evendale,
Ohio, as part of the first eCore tests. The results were very positive.
CLEEN funding will help advance dynamic modeling and size scaling of the
TAPS II combustor.

*    Flight Management System – Air Traffic Management (FMS-ATM):
Advanced FMS-ATM technology will enable commercial and military aircraft
to routinely fly more optimum trajectories resulting in less fuel,
emissions and noise. The CLEEN award will include technology
demonstrations with Lockheed Martin, AirDat and Alaska Airlines. The
program will develop and demonstrate two primary components:
*    Improvement to GE’s FMS trajectory algorithms for fuel,
emissions and noise performance,
*    Development of technology to enable the airborne FMS to
digitally exchange information with the En Route Automation
Modernization (ERAM) developed and deployed by Lockheed Martin. This
allows the FAA to enable the 4-dimensional trajectory-based FMS to fly
more optimum trajectories within the national air space.

*    Open Rotor: Back in the 1980s, GE successfully ground tested and
flew an open rotor or unducted fan engine, which offered significant
fuel efficiency advantages over conventional ducted fan engines. By
applying today’s advanced data acquisition systems and computational
design tools to the open rotor engine, GE has improved the design to
reduce fuel consumption by 26 percent and address noise challenges. Last
year, GE started wind tunnel testing with NASA to evaluate
counter-rotating fan systems for an open rotor engine. The CLEEN award
will support blade aero-acoustic and pitch change mechanism research.
Open rotor engine designs are among the longer-term technologies being
evaluated for the LEAP-X engine.
