HondaJet F3

3 December 2003 Japanese car company Honda introduced its first aircraft designed for serial production and mass sales. This is the first aircraft in Japan, as a whole (including engines) made by a single company without any government support.

For Honda aircraft has developed a turbojet engine, the HF118 year and have tested it by setting the left pylon of the aircraft Citation Jet.

The Honda Jet engines mounted on pylons above the wing, like the German VFW-614. This arrangement will reduce the noise level, downward (on earth noise, especially during takeoff and landing). In addition, the improved flow around the upper surface of the wing and reduces the chance to be sucked into the air intake of a foreign object from the runway. However, the air flow structure is complicated, so it took intensive experiments in a wind tunnel. The stability of the engines when this arrangement was tested for angles of attack up to 26° .

The fuel is stored in two wing caisson-tanks, the supply tank and the tank in the rear fuselage. The system of centralized refueling.

Was developed and a special laminar wing profile SHM-1. The section of the wing with such a profile were tested on the flying laboratory T-33. To do this right on the hull of the T-33 with the help of polyurethane foam formed to the desired server and sheathed with fiberglass. Under the new sheathing installed 119 pressure sensors. The transition from laminar to turbulent flow were recorded by an infrared camera mounted in the cockpit of T-33 (in turbulent flow the air is slightly warmed up).

30% of the wing span of the flaps installed, deviant 15.7° during takeoff and 50° for landing. Wing and tail are aluminum. The plumage is T-shaped.

The anti-icing system on the wing leading edge is fed with warm air from the engines. Glass cockpit are heated electrically. However, there is no information on the protection against icing of the tail and intakes.

The fuselage is made of precomposing materials with aluminum supports, the fore part flattened for laminar flow. The company claims that as a result, the fuselage drag is reduced by 10 % compared to conventional fuselages of the same size.

The cabin is sealed, at a height of 13 km is supported by the pressure corresponding to the pressure at the altitude of 2.4 km above sea level in the standard atmosphere (maximum boost — 0,61 ATM).

Chassis tricycle, hydraulically retracted. Nosewheel has a control system, and is deflected to the left and to the right at 50° when taxiing and 10° during the run.

In static tests the wing and fuselage were loaded only to 80 % design load, and the behavior at 100 % loads were simulated by computers. As a result, the glider is held static testing, was used for the construction of a flying prototype. Only the plumage is tested under a full load.

Honda plans to sell in the U.S. Hondajet as a lightweight, inexpensive jet aircraft, business class.
