Engine To Power Honda's Advance Light Jet
Engine assembly has begun on the GE Honda Aero Engines' first
HF120 engine for FAA certification testing. The first engine is
being assembled consistent with the certification configuration at
GE's manufacturing facility in Lynn, Massachusetts.
"With the experience we've gained through our demonstrator
engine testing program, we are confident the HF120 engine
configuration is mature and are anticipating a smooth FAA
certification testing program," said Bill Dwyer, president of GE
Honda Aero Engines. "The first engine to test will run by the end
of the summer, and certification testing will continue into
The HF120 engine has experienced one of the most extensive
engine test programs prior to the official start of FAA
certification testing. To date, GE Honda Aero Engines has built and
tested eight HF120 engine cores and 11 full engine demonstrators.
During testing, the engine has exceeded its design goal of 2095 lbs
Thirteen HF120 development engines will take part in the
certification testing at seven locations in the U.S. and Japan.
Tests will include fan blade out, crosswind, stress and endurance
testing. GE Honda also plans to test the engine on a flying testbed
before flying on the customer certification aircraft. By entry into
service, the HF120 will have accumulated more than 15,000 cycles of
ground and flight testing.
HF120 engine production will initially begin at GE's site in
Lynn, Massachusetts and will later transition to Honda Aero Inc.'s
recently completed engine production and overhaul facility in
Burlington, North Carolina.
The GE Honda HF120 engine was launched in 2006 and selected to
power Honda Aircraft's advanced light jet, the HondaJet, and the
Spectrum Aeronautical "Freedom" business jet.
Rated at 2,095 pounds of thrust, the HF120 engine succeeds
Honda's original HF118 prototype engine, which has accumulated more
than 4,000 hours of testing on the ground and in-flight. GE and
Honda redesigned the engine for higher thrust and new standards of
performance in fuel efficiency, durability, and low noise and
The HF120 technologies include:
- A wide chord, compound-swept front fan and two-stage booster
along with composite outlet guide vanes.
- A high-temperature, titanium impellor in the compressor for
maximum engine pressure ratio and stall-free performance.
- A compact reverse-flow configuration combustor and single-stage
air-blast fuel nozzles.
- Advanced materials in the turbine as well as a two-stage
low-pressure (LP) turbine and a counter-rotating high-pressure and
LP spool shaft system.
A key cost-of-ownership advantage of the HF120 will be the
ability to operate at a best-in-class 5,000 hours between major
overhauls. The advanced airfoil materials and coatings that GE and
Honda are maturing for the engine's high-pressure turbine section
enable this capability.
In 2004, GE and Honda formed a 50/50 joint venture, called GE
Honda Aero Engines, based in Cincinnati, Ohio. The joint company
integrates the resources of GE and Honda Aero, Inc., a Honda
subsidiary established to manage its aviation engine business.
