GE Honda Aero Engines is putting the
HF120 turbofan through its paces during the engine’s year-long certification tests, Bill Dwyer, president of GE Honda Aero Engines, told AIN during a recent visit to the company’s Cincinnati facility. Type certification is expected in the first quarter of next year.

Formal certification testing of the HF120 started in late July last year after an extensive demonstrator program and finalization of the design. The HF120 has a wide-chord, compound-swept front fan and two-stage booster, along with composite outlet guide vanes. The engine employs a high-temperature titanium impellor in the compressor for maximum engine pressure ratio and stall-free performance, two-stage low-pressure (LP) turbine and a counter-rotating high-pressure and LP spool shaft system, and a compact reverse-flow combustor with single-stage air-blast fuel nozzles.

GE Honda Aero Engines is targeting the 1,000- to 3,500-pound-thrust business and general aviation engine market. The GE Honda HF120 was launched in 2006 and selected to power Honda Aircraft’s light jet, the HondaJet, and the Spectrum Aeronautical Freedom.
