NBAA: New GE engine for Bombardier's top end Globals

Bombardier has selected GE Aviation to provide the integrated powerplant system for the new Global 7000 and Global 8000 business jets, launching the development of a new business jet engine for GE, currently called the TechX engine.

The TechX engine will further strengthen 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.  The engine will incorporate advanced technologies from both GE's  commercial and military engines developed with the company's annual $1B  investment in new technology research and development.      

The TechX engine will deliver several benefits, including: 8 percent  lower specific fuel consumption than current business jet engines in the  10-20K thrust class, more than 50 percent margin to CAEP/6 regulations  on all emissions (NOx, smoke, hydrocarbons and CO) and world-class  performance and reliability.    

"This selection of the TechX engine to power Bombardier's Global 7000  and Global 8000 business jets significantly expands GE's Business and  General Aviation product portfolio and enables us to bring GE's advanced  technology to this business aviation segment," said Brad Mottier, vice  president and general manager of GE Aviation's Business and General  Aviation organization.   

The TechX engine will produce around 16,500 pounds of thrust and  incorporate advanced technologies, such as:

  • A composite fan case and a unique front fan blisk that will  reduce weight and lower cabin noise and vibration; GE's eCore technology, including: 
  • High pressure ratio, 10-stage compressor with advanced materials  for enhanced reliability and durability and improved fuel consumption.                                      
  • Latest generation 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,                                       
  • High pressure turbine with advanced material and  cooling design for enhanced durability and improved performance;
  • Integrated propulsion system with a slim-line nacelle with  outward opening lower cowl to reduce weight and drag while allowing for  easy maintenance access and high availability.    

Core testing of the eCore technologies are already underway with the  eCore Demonstrator 2 to run next year. The TechX engine is scheduled to  begin testing in 2013.
