Company Says It Is "Meeting Design Objectives" In All Categories

GE Honda Aero Engines continues to make steady progress toward certification of the HF120 engine. "The HF120 engine has demonstrated that it is meeting design objectives for thrust, fuel burn and operability," said Bill Dwyer, president of GE Honda Aero Engines.

The HF120 engine has undergone a comprehensive test program in an altitude chamber at GE Aviation's Evendale, OH, facility. Testing has included operation to 46,000 feet altitude and high Mach, as well as testing for performance, transients, air starts, and extreme hot and cold conditions. Other component tests and full engine tests to verify design robustness have been completed, including tests such as operation in crosswind and hail ingestion at GE Aviation's Peebles, OH, facility.

Thirteen HF120 engines and two core builds will take part in the certification testing at six test site locations. Currently five HF120 certification engines are on test simultaneously with one engine completing 500 durability cycles. GE Honda Aero Engines also plans to test the engine on a flying testbed before flying on a customer certification aircraft. With FAA certification planned in 2011, the HF120 engine will complete more than 15,000 cycles of ground and flight-testing prior to entry into service.

The HF120 engine has undergone an extensive design verification program prior to the official start of FAA certification, including eight core engine builds and eleven turbofan builds. Design optimization and verification was also conducted via compressor, combustor, fan and mixer rig tests.

HF120 engine production will initially begin at GE's site in Lynn, MA, and will later transition to Honda Aero Inc.'s engine production and overhaul facility in Burlington, NC.
