The Honda HA-420 HondaJet is the first general aviation aircraft developed by the Honda Aircraft Company.

Development[edit]

Honda began to study small sized business jets in the late 1980s, using engines from other manufacturers. The Honda MH02 was fabricated and assembled at Mississippi State University's Raspet Flight Research Laboratory in the late 1980s and early 1990s. The MH02 was a prototype using carbon fiber/epoxy composite materials.[3] Flight testing on the MH02 continued through 1996, after which the aircraft was shipped to Japan.

The prototype HondaJet made its maiden flight in December 2003. It debuted to the public at the EAA AirVenture air show in Oshkosh, Wisconsin, in July 2005. On July 25, 2006, Honda returned to Oshkosh to announce it would commercialize the HondaJet. Honda established the Honda Aircraft Company to seek both type and production certification of the HondaJet. Production is to take place in the United States. The company began taking customer orders in the fall of 2006. The price was about US$3.65 million. At that time the company expected to build 70 jets per year.

In August 2006 Honda and Piper Aircraft announced a partnership to market the HondaJet.[4]

In May 2010 major assembly of a type-conforming air-frame started. Components included the composite fuselage, metal wings, empennage, landing gear and over-the-wing-mounted engine pylons. Work was then in progress to integrate major systems, including electrical, hydraulic and environmental control. The first conforming engine was to be delivered in the third quarter of 2010 and be installed on the aircraft. Honda Aircraft planned to begin static testing of a conforming airframe in May 2010.[5]

The maiden flight of the prototype aircraft was scheduled for November 2010. Because of delays in some components, the flight actually took place on 21 December.[6][7] FAA certification and delivery were repeatedly delayed,[8] including a one-year delay caused by the engine's susceptibility to ice damage.[9]

With the engine having achieved certification, the aircraft's certification is targeted to be in the first quarter of 2015.[10] First flight of the production model occurred on 27 June 2014[11][12] and was flown and shown at Oshkosh Airshow soon after.[13][14]

Design[edit]

Honda chose an unusual over-the-wing podded engine configuration, which had been seen on the innovative Vereinigte Flugtechnische Werke VFW-614 decades earlier. It allows for more space within the fuselage (due to elimination of engine-mount bulkheads aft of the passenger area) and reduces drag at high speeds. The fuselage is made of lightweight composite materials. The wings are made from structurally reinforced single sheets of aluminum,[6] which allows for a smoother surface than more conventional methods. Design testing on wing shape and design were carried out on a Lockheed T-33 jet fighter which had been modified by AVTEL Services, Inc., and flight tested at the Mojave Airport.

Honda began developing its own small turbofan engine, the HF118, in 1999. This led to the HF120, developed with GE Aviation under the GE-Honda partnership. The HF120 was test-flown both on a Cessna Citation and a modified Boeing 727-100. The engine features a single fan, a two-stage compressor and a two-stage turbine.

Honda claims that the combination of lightweight materials, aerodynamics and efficient engines gives the HondaJet as much as 35% higher fuel efficiency than similar aircraft.

The aircraft is equipped with a touchscreen 3-display Garmin G3000[6] glass cockpit system (i.e. most of the cockpit readouts are presented on flat-panel displays).

Production[edit]

The aircraft will be made at Piedmont Triad International Airport, Greensboro, North Carolina, USA. Construction of the factory began in 2007 and was completed in late 2011.[6][15] In July 2011 members of the media were invited to tour the facility, which was still under construction. At that time company representatives announced that certification was expected, and production of the airplane would begin late in 2012.[16]

In 2008 the Honda executives predicted that they would sell 70 planes per year.[17] In July 2011 they indicated their plan is to produce (and therefore sell) 70 to 100 planes per year.[18] At the time of the first flight of the first production unit, company President and CEO Michimasa Fujino predicted that the first year's production would be 50 units, the next few years would see 90 units per year, and long-term production stabilizing at 80 units per year.[19]

On October 29, 2012 Honda announced that the HondaJet was entering production.[20] The first production HondaJet debuted at the 2014 EAA Airventure Airshow, with first deliveries soon after.[21][22]

Legal actions[edit]

HondaJet is the only aircraft which has been removed from the open-source FlightGear simulator. In June 2014 Honda lawyers issued a takedown request in which they claimed that the use of the HondaJet model in the simulator infringes upon Honda's trademarks.[23]
