Honda HA-420 HondaJet
HA-420 HondaJet - a twin-engine jet aircraft Business Class.
In December 2003 Japanese automobile company Honda has presented its first aircraft HA420 Honda Jet (first flight - 03 December 2003), which is intended for the serial production and sales. It is the first aircraft in Japan as a whole (including engines) manufactured by the same company without any government support.
Honda has developed for aircraft Bypass Turbofan Engine HF118 and felt it a year setting on the left pole at the aircraft CitationJet. Honda Jet engines mounted on pylons above the wing as the German VFW614. This arrangement makes it possible to reduce the noise level, which is directed downwards (noise on the ground, especially during landing and take-off).

Besides, it is much better to wrap the upper part of the wing, and less likely to suck the runway foreign object into the air intake. But the complicated structure of the air flow, because it took extensive experiments using a wind tunnel. Stability of the motors for this arrangement tested for angles of attack up to 26. Fuel is saved in two integral fuel tank in the wing, rear fuselage tank and the supply tank. Centrally controlled refueling.
It was designed a special laminar airfoil SHM1. Section wing with the profile tested to the flying laboratory T33. To do this directly on the skin of T33 using polyurethane foam formed desired profile and trimmed it with fiberglass. Under the new skin 119 mounted pressure sensors. The transition to turbulent flow from laminar fixed infrared camera that is mounted on the cab T33 (air in a turbulent flow a little warming up).

In 30 percent wingspan installed flaps, which are deflected by 15,7gradusov during takeoff and landing 50 degrees. The plumage and wing aluminum. A T-tail. The fuselage is made of carbon composite materials with reinforcing aluminum elements, for laminar flow flattened nose. The company claims that as a result of the resistance of the fuselage reduced by 10 percent in comparison with conventional fuselages of similar size. Cabin length 4,6m height - just 1,5m. The pressurized cab, at the height of 13km support pressure which corresponds to the pressure 2,4km above sea level (standard environment, the greatest boost - 0,61atm). On the front side of the wing de-icing system is powered by the engine warm air. The glass in the cockpit electrically heated.
But there is no data for the Protection of feathers and the air intakes of the icing. Tricycle landing gear, hydraulics removed. At the nose gear wire control system, which is deflected to the right and to the left on 50 degrees during taxiing and 10 degrees during the run. The fuselage and wing for static tests were run only up to 80 percent of design loads and behavior 100 percent load was simulated with the help of computers. As a result, the glider, which passed a static test, was used for the construction of the prototype flight personnel. Only the tail is tested under full load. Honda plans to sell in the United States as a jet Hondajet inexpensive, lightweight aircraft Business Class.
Construction of the plant for the production of airplanes Honda completed in the early 2011. A first aircraft customers received 2012 year. Cost HondaJet about 4,5 million. Dollars.
