GE Honda Aero Engines Thoroughly Testing the HF120 Engine

(May 24, 2007) -- With successful tests of a HF120 engine core completed in April, GE Honda Aero Engines is preparing to run a second core test in May, followed by a full engine test in July.

They are part of several key tests in 2007 to validate design enhancements as the HF120 readies to power business jets by 2010. Also in 2007, GE Honda Aero Engines will finalize design and release hardware for the first HF120 engines that will undergo certification testing in 2008.

The GE Honda H120 engine was formally launched in October 2006 when it was selected to power both the HondaJet advanced light jet and the Spectrum Aeronautical "Freedom" business jet. To date, more than 200 HF120 engines are on order. HF120 certification is targeted for 2009, with entry into service on both aircraft scheduled to begin in 2010.

Early in the next decade, the annual production capacity for the HF120 engine is expected to reach 140 engines, which is based on the promising outlook for new-generation light business jets.

The HF120 engine, rated at 2,050 pounds of thrust, 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, while seeking new standards of performance in terms of fuel efficiency, durability, and low noise and emissions.

GE Honda tested the redesigned HF120 core (compressor, combustor, high-pressure turbine) at Honda's WAKO R&D Center in Japan in March and April. The tests validated the aeromechanical characteristics of the compressor and turbine airfoils. The second core test in May will focus on overall component performance and engine thermal characteristics.

"The full turbofan engine test in July will demonstrate performance and systems capabilities," said Bill Dwyer, president of GE Honda Aero Engines. "We have an aggressive 2007 test plan to assure that our final design is ready for certification. We are very encouraged with the recently completed core tests."
