The FAA has awarded Part 33 certification to GE Honda Aero Engine’s HF120 turbofan engine, certifying its airworthiness and setting the stage for the production of this all-new engine, which will power the new HondaJet.
The HF120 engine’s airworthiness certification follows an extensive ground and flight test program that involved 13 engines. During its certification program, the HF120 engine accumulated more than 14,000 cycles and 9,000 hours of testing.
“Achieving U.S. FAA airworthiness certification for the HF120 engine is a perfect way to end the year for the GE Honda Aero Engine team,” said Terry Sharp, president of GE Honda Aero Engines. “And this is just the beginning for our team, which has worked tirelessly to demonstrate the technologies in our engine. We have been ramping up the supply chain and production processes to prepare for a successful entry into service.”
Assembly is currently under way at GE’s facility in Lynn, Mass., which is responsible for initial production. Production will transition to the Honda Aero Inc. facility in Burlington, N.C., next year.
GE Honda is establishing its customer service and support operation. The support model will consist of a network of GE Honda Authorized Service Providers, a 24/7 GE Honda Operations Center, dedicated Field Technical Managers (FTMs) and Customer Team Managers (CTMs), among other support operations. GE Honda will offer long-term engine service agreements with Enhanced and Comprehensive maintenance and support services that go above and beyond the basic engine warranty, with coverage of both scheduled and unscheduled maintenance events.
Rated at 2,095 pounds of thrust, the HF120 engine includes technologies such as:
- A wide-chord, compound, swept front fan blisk, along with composite outlet guide vanes.
- A high-temperature titanium impeller 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 high-pressure (HP) turbine as well as a two-stage low-pressure (LP) turbine and a counter rotating HP and LP spool shaft system.
Company officials said the HF120 will be able to operate at a “best-in-class” 5,000 hours between major overhauls. The advanced airfoil materials and coatings that GE and Honda have developed for the engine’s HP turbine 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 Aviation and Honda Aero, Inc., a Honda subsidiary established to manage its aviation engine business. The GE Honda HF120 engine program was launched in 2006 and was selected to power Honda Aircraft Company’s advanced light jet, the HondaJet.
