TheGE Honda HF120 is a smallturbofan for thelight business jet market, the first engine to be produced byGE Honda Aero Engines.
Succeeding Honda's originalHF118 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 toBurlington, 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]
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 low NOx, CO and HC. Noise levels are quieter than Stage 4 requirements.[6]
In May 2016time between overhaul was 2,500 h, which was expected to mature to 5,000 h; a midlife hot-section inspection is not required, and it is expected to remain on wing 40% longer than other engines and have lower operating costs.[7]
Besides theHondaJet, HF120 was announced as a retrofit to theCessna CitationJet CJ1 bySierra Industries,[8] in partnership with GE Honda.[9]
In addition,Spectrum Aeronautical has announced it is planning to use HF120 for its upcomingS-40 Freedom.[10]
