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).

At 30 percent of the wing span flaps are installed, which deviate by 15,7 degrees during take-off and 50 degrees when landing. Plumage and the wing are aluminum. T-shaped plumage. The fuselage is made of carbon composite materials with reinforcing aluminum elements, the nose is smoothed for laminar flow. The company claims that, as a result, the fuselage resistance is reduced by 10 percent compared to conventional fuselages of similar size. The length of the cabin is 4,6m, the height is only 1,5m. Sealed cabin, at a height of 13km maintain a pressure that corresponds to the pressure of 2,4km above sea level (standard atmosphere, the largest boost is 0,61atm). At the front end of the wing, the anti-icing system is powered by warm air from the engines. The glasses in the cockpit of the pilots are electrically heated.

But there is no data on protection of plumage and air inlets from icing. Three-column chassis, hydraulically retracted. At the bow stand the remote control system, which deviates to the right and left by 50 degrees when steered and at 10 degrees during takeoff. The fuselage and wing in static tests were loaded only up to 80 percent of design loads, and the behavior at 100 percent of the loads was modeled with computers. As a result, the glider, which passed the static tests, was used to build an airplane prototype. Only plumage is tested under full load. Honda plans to sell in the US Hondajet as a reactive low-cost, light business-class aircraft.

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.
