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
![](../I/m/HondaJet_005.jpg)
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]
