General Electric Passport
The General Electric Passport (formerly called TechX) is a high bypass turbofan engine currently under development by GE Aviation, in cooperation with Safran.〔Norris, Guy, Close to the finish, Aviation Week & Space Technology, January 15 - February 1, 2015, p.27〕 It is designed to produce power in the thrust category, such as the Bombardier Global 7000 and 8000. It is being developed in parallel with the larger CFM International LEAP, and includes many similar technologies, like blisks and NOx reducing combustors.〔("GE TechX engine set to lead new generation of GE turbofans" ) By John Croft, Flightglobal. 19 May 2010〕 GE sees potential in using the engine both on large cabin business jets and regional aircraft, where it will replace the CF34 in GE's product line.
The Passport 20 engine final assembly will be performed at GE Aviation's plant at Strother Field in Arkansas City, Kansas.
==Development==
GE is developing the core from the LEAP-X eCore technology, using a metal fan blisk, the first application of such technology on an engine this size. In addition to eliminating the need to balance a hub and blade system, the blisk eliminates air leaks around the fan blades, thus improving its aerodynamic efficiency.〔("NBAA: GE TechX fan blisk is all the buzz" ) By John Croft, Flightglobal. 21 October 2010〕 The testing of the engineering cores began in 2010, with a second core set to be ready in 2011.〔 Passport will also feature a slimline nacelle with clam-shell cowl opening; these features reduce weight and drag.〔
On May 16, 2011, the TechX was renamed the Passport.〔(GE rebrands TechX as Passport )〕 On December 30, 2014, GE mounted the first 16,500 lb thrust Passport engine on its Boeing 747-100 flying engine test bed. GE also completed hail and bird ingestion tests for the engine.
