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.
Development
Succeeding Honda's original HF118 prototype, the HF120 was undergoing testing in July 2008, with certification targeted for late 2009.[2] The first engines were produced at GE's factory, but in November 2014 production shifted to Burlington, North Carolina.[3] The U.S. Federal Aviation Administration (FAA) awarded Part 33 certification to the HF120 turbofan engine in December 2013, and production certification in 2015.[4]
Design
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.[5] The HF120 engine’s components interact with greater efficiency by incorporating 3D aerodynamic design and its effusion-cooled combustor design emits few NOx, CO and HC. Noise levels are quieter than Stage 4 requirements.[6]
Applications
The engine is offered as a retrofit to the Cessna CitationJet CJ1 by Sierra Industries,[7] in partnership with GE Honda, besides the Hondajet.[8]
