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.
