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 developed the HF118 turbojet engine for the aircraft and tested it for a year by installing it on the left pylon near the CitationJet aircraft. Engines on the Honda Jet are mounted on pylons over the wing, like 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 takeoff).

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.

A special laminar wing profile SHM1 was designed. The wing section with this profile was tested on the T33 flying laboratory. To do this, directly on the T33 casing with the help of polyurethane foam formed the necessary profile and sheathed it with fiberglass. Under the new skin, the 119 pressure sensors were mounted. The transition to turbulent flow from the laminar flow is fixed by an infrared camera, which is installed on the Т33 cabin (the air in the turbulent flow warms up a little).

On the 30 percent wing span, flaps are installed, which deflect to 15,7 degrees when taking off and 50 degrees when landing. Aluminum plumage and wing. T-shaped plumage. The fuselage is made of carbon composite materials with reinforcing aluminum elements, for the laminar flow around the nose is smoothed. The company claims that as a result, the fuselage resistance is reduced by 10 percent compared to conventional fuselages of similar size. Cabin length 4,6м, height - total 1,5м. Sealed cabin, at a height of 13km, maintains a pressure that corresponds to a pressure of 2,4km above sea level (standard atmosphere, the highest charge - 0,61atm). At the front end of the wing, the anti-icing system is powered by engines with warm air. Glasses in the cockpit 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.
