The General Electric Passport is a turbofan developed by GE Aerospace for large business jets . It was selected in 2010 to power the Bombardier Global 7500 and 8000, first run on June 24, 2013, and first flown in 2015. It was certified in April 2016 and powered the Global 7500 first flight on November 4, 2016, before its 2018 introduction. It produces 14,000 to 20,000 lbf (62 to 89 kN) of thrust, a range previously covered by the General Electric CF34 . A smaller scaled CFM LEAP , it is a twin-spool axial engine with a 5.6:1 bypass ratio and a 45:1 overall pressure ratio and is noted for its large one-piece 52 in (130 cm) fan 18-blade titanium blisk .

GE Honda HF120 The GE Honda HF120 is a small turbofan for the light business jet market, the first engine to be produced by GE Honda Aero Engines . Succeeding Honda's original HF118 prototype, the HF120 was undergoing testing in July 2008, with certification targeted for late 2009. The first engines were produced at GE's factory, but in November 2014 production shifted to Burlington, North Carolina . The U.S. Federal Aviation Administration (FAA) awarded Part 33 certification to

162-601: The HF120 turbofan engine in December 2013, and production certification in 2015. The engine has a wide-chord swept fan, two-stage low-pressure compressor and counter rotating high-pressure compressor based on a titanium impeller, for a 2,050 lbf (9.1 kN) takeoff thrust. The HF120 engine's components interact with greater efficiency by incorporating 3D aerodynamic design, and its effusion-cooled combustor design emits low NOx, CO and HC. Noise levels are quieter than Stage 4 requirements. In May 2016 time between overhaul

180-483: The Passport titanium blisk is larger than the GE90 first stage compressor blisk. The 18 highly twisted wide chord forged titanium blades are friction welded by translations to the hub. The one piece fan reduces the vibration for cabin comfort, lowers wear and maintenance due to fewer parts, is lighter by a third and improves performance with less leaks and a smaller hub. Fuselage-mounted business jet engines are high off
