GE Honda Aero Engines to Power HondaJet Advanced Light Jet

October 17, 2006

ORLANDO, Fla. -- GE Honda Aero Engines and Honda Aircraft Company, Inc. have signed a business agreement to power the new HondaJet advanced light jet with the GE Honda Aero Engines HF120 turbofan engine. 

"The HF120 is beautifully suited for the HondaJet," said Gary Leonard, president of GE Honda Aero Engines. "This next-generation advanced light jet utilizes lightweight composites and advanced aerodynamics. We are thrilled to bring our engine technologies to the HondaJet, an exciting new entry in the promising light business jet arena." 

For two years, GE and Honda have engaged in aggressive development and component testing for the new HF120 engine, with the first engine scheduled to run in early 2007. 

Certification for the HF120 production engine is targeted for 2009. The HondaJet is targeted for certification and entry into service in 2010. 

GE Honda's HF120 engine will be rated at 2,050 pounds of thrust. It is a higher-thrust successor to Honda's original HF118 development engine, which has accumulated more than 4,000 hours of testing on the ground and in-flight - and was the engine used for full development and testing of the prototype HondaJet. 

Drawing from GE's and Honda's technology leadership and experience, the HF120 is being designed and tested with the goal of setting new standards of performance for small jet engines in terms of fuel efficiency, durability, and low noise and emissions. 

"Since the joint company was formed in 2004, the collaboration between GE and Honda has been outstanding," said Leonard. "We are fully focused on introducing new propulsion technologies that will raise the bar for these types of applications." 

Since 2005, the GE Honda team has run several component tests for the new design, including core-engine and high-pressure turbine endurance testing, and front fan bird ingestion testing at Honda facilities in Japan; and icing tests at GE's test facilities near Cincinnati, Ohio. 

The HF120 technologies include: 

*Fan section: A 18.5-inch-diameter, wide-chord, compound, swept fan and two-stage booster. The fan and booster are GE Honda blisk designs with the latest 3D aerodynamics, drawing from the technology used to design GE's GEnx engines and Honda's Formula One experience for lower weight and efficiency. The outlet guide vanes are fabricated from composite material for weight reduction. 

*Compressor: Features a high temperature, titanium impeller developed by Honda over the past 20 years, designed to achieve maximum engine pressure ratio and stall-free performance. 

*Combustor: Based on the Honda HF118 design, the combustor features a compact reverse-flow configuration and single-stage air-blast fuel nozzles. The Hastelloy liner features laser-drilled multi-hole cooling.  

*Turbine: For durability at high temperatures, powder metal disk and single-crystal high-pressure turbine (HPT) blade materials from the GEnx engine have been incorporated. The low-pressure turbine (LPT) is a two-stage configuration. Also, a counterrotating HPT and LPT system reduces weight. 

A key cost-of-ownership feature of the HF120 will be the ability to operate in service for an industry record-setting 5,000 hours before the first major overhaul with no need to open the engine for interim hot-section inspections. Keys to this capability are the advanced airfoil materials and barrier coatings that GE and Honda are maturing for the engine's HPT section. 

The emergence of small, less expensive business jets creates considerable opportunity for highly reliable and durable jet engines. The GE Honda HF120 durability will be ideally suited for highly utilized aircraft, such as the emerging air taxi industry. Lightweight, efficient design enables the performance, range and comfort required by the business jet customer. 

GE Honda Aero Engines envisions annual sales of at least 400 aircraft in the thrust class of the HF120 engine. 

Honda (NYSE: HMC) is the world's largest engine manufacturer, annually producing more than 20 million engines for a wide range of products, including motorcycles, ATVs, generators, marine engines, lawn and garden equipment, and Honda and Acura automobiles.  

GE - Aviation, an operating unit of General Electric Company (NYSE: GE), is one of the world's leading manufacturers of jet engines for civil and military aircraft. GE also is a world-leading provider of maintenance and support services for jet engines. GE traces its beginnings to Thomas A. Edison, who established Edison Electric Light Company in 1878.
