General Electric Company and Honda have jointly developed the HF120 turbofan engine to be installed in the HondaJet. Both GE and Honda brought their leading technologies to the HF120 program and targeted top-class light weight, low fuel consumption, and low emissions as key design goals for the small turbofan engine. The HF120 improved specific fuel consumption by 3% and thrust-weight ratio by 17% compared with an earlier HF118 turbofan engine that Honda had developed independently. In addition, the HF120 complied with emissions regulations for larger turbofan engines that currently do not apply to small engines in its class. Notable features of the HF120 include wide chord swept fan, carbon composite fan stator vane, high-efficiency centrifugal compressor, effusion-cooled combustor, and air-blast fuel nozzle. The HF120, with these and other technologies, received a Type Certificate from the United States Federal Aviation Administration in December 2013.
