GE Honda HF120
The GE Honda HF120 ( development model has been referred to as HF118 ) is a small turbofan engine for light business jets.
Development
The engine is a product of GE Honda, which is an existing since 2004 joint venture between the US-based engine manufacturer GE Aviation and the Japanese company Honda. It is to be installed as the first in the HA -420 HondaJet, but later also in other manufacturers' aircraft ( eg Spectrum S-40 Freedom ). The engine has a fan with curved blades large blade chord and is controlled via a dual channel FADEC system. The fan and the low pressure compressor are equipped with blisks. The centrifugal high pressure compressor is made of titanium (leaves from a single crystal ). A special feature is the built space reasons reversing combustion chamber and the counter-rotating high and low pressure waves.
The first run took place on 11 September 2007 at the test center by Honda in Tokyo, with a maximum thrust of 9.31 kN was reached. The Acceptance testing should start in 2008. The first flight was in 2010 and announced the first delivery in 2011. The first flight of the machine with the mounted HF120 engines found on 20 December 2010 at the Piedmont Triad International Airport in Greensboro (North Carolina) instead. Since construction problems arose with the engine, the aircraft delivery was so delayed at mid-2013.
