Description: The General Electric (GE) TechX, now called Passport, is a 16,500-lb thrust class turbofan intended to power ultra long-range business jets. It incorporates technologies developed by GE for both commercial and military engines. TechX engine delivers 8% lower specific fuel consumption than current jet engines in the 10,000-20,000 pounds thrust class, more than 50% margin to CAEP/6 emissions regulations (NOx, Smoke, hydrocarbons and CO) and outstanding performance and reliability. In October 2010, Bombardier selected the GE TechX engine to power its new Global 7000 and Global 8000 ultra long-range, large cabin business jets expected to enter service in 2016 and 2017 respectively. The TechX engine is scheduled to begin testing in 2013.
Key advanced technologies provided to the TechX jet engine are: a composite fan case and a unique front fan blisk that will reduce weight and lower cabin noise and vibration; GE eCore technology under development and planned for 2013; and an 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.
The eCore delivers high pressure ratio incorporating a 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; and high pressure turbine with advanced material and cooling design for enhanced durability and improved performance.
