Engine For Bombardier Global 7000 And Global 8000 Business Jets
Incorporates TechX Technologies
GE Aviation's integrated propulsion system, which includes the
engine, nacelle and thrust reverser, for the new Bombardier Global
7000 and Global 8000 business jets has been named Passport.
"Initially, we called GE's development program of this new
engine the "TechX," to highlight advanced technologies incorporated
from commercial and military applications being uniquely adapted
for business jets," said Brad Mottier, vice president and general
manager of GE's Business & General Aviation organization. "This
new name, Passport, is a better representation of the product - the
world's first integrated propulsion system specifically designed
for ultra long-range, large cabin business jets, giving customers
the power to fly powerfully, more quietly and efficiently -
anywhere they want to go."
The Passport product line further strengthens GE's presence in
the ultra long-range, large cabin business aviation segment, which
includes aircraft that can travel up to 7,900 nautical miles with 8
passengers. GE says the Passport engine will deliver several
benefits, including at least 8% lower specific fuel consumption
than current business jet engines in the 10-20K thrust class, more
than 50% margin to CAEP/6 regulations on all emissions (NOx, smoke,
hydrocarbons and CO) and world-class performance and
reliability.
The Passport engine for the Global 7000 and Global 8000 business
jets will produce up to 16,500 pounds of thrust and incorporate
advanced technologies, including a composite fan case and a unique
front fan blisk that will reduce weight and lower cabin noise and
vibration, and GE's "eCore" technology, which includes high
pressure ratio, 10-stage compressor with advanced materials for
enhanced reliability and durability and improved fuel consumption,
a Twin Annular Pre-mixed Swirler II (TAPS II) combustor that will
produce fewer NOx emissions throughout the flight envelope compared
to current business jet engines in this segment, and high-pressure
turbine with advanced material and cooling design for enhanced
durability and improved performance.
The Passport integrated propulsion system will feature a
slim-line nacelle with outward opening lower cowl to reduce weight
and drag while allowing for easy maintenance access and high
dispatch availability.
Core testing of the eCore technologies are already underway with
the second eCore demonstrator running in mid-2011. Additional tests
planned for this year include fan blade out rig, fan aerodynamic
rig, and TAPS Combustor rig, in an effort to mature new
technologies leading up to first engine to test in 2013.
