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.
