Airplane "Argo 02"

 

Is it real nowadays to create an airplane on our own? Tver amateur amateurs Yuri Gulakov, Yevgeny Ignatiev and Alexander Abramov could do this by constructing a single-seat aircraft, later named "Argo-02". The device turned out good, it participated in republican competitions and won first place in the regional competition of amateur aircrafts, which was held in Yaroslavl. Such success of "Argo" was provided, first of all, using traditional, time-tested technologies for designing wooden aircraft with a modern miscalculation of the aerodynamic characteristics of this class of vehicles.

Argo 02 aircraft cabin

Perhaps it was one of the main advantages of the aircraft: its manufacturing does not need plastic and composite materials, synthetic fabrics and high-hire. All that is needed - a pine board, canvas, a little plywood and enamel.

 

Design

 

"Argo-02» - this ultra-light training aircraft, presented nizkoplanom classical cantilever structures made of wood, which has a cantilever tailplane. The device is equipped with a spring landing gear with tail wheel. As the power plant is used two-cylinder two-stroke engine with air cooling type RMZ-640, which by means of a V-belt gear launches dvuhlopasny monoblock wooden propeller to rotate.

 

In the cockpit there aerobatic team of instruments and devices-indicators, which reflect the work of the engine. Fuselage is wooden, has raskosnofermennuyu structure spars are made of wooden slats (cross section 18h18 mm). On top of the fuselage behind the cockpit is easy gargrot, the basis of which are wooden stringers and aperture, as well as the dural lining thickness 0,5 mm.

The tail part of the fuselage and the cockpit are trimmed with 2,5 mm plywood. The rest of the surface of the structure is covered with linen. Through the control cabin are the spars, to which the leather seat of the pilot and the aircraft control post are fixed. Inside the sides of the cabin are covered with foam and artificial leather. The ore is located on the left side. The dashboard is made of sheet duralumin, top covered with enamel. The mounting of the dashboard is carried out by means of shock absorbers to the frame No. 3. The front part of the fuselage under the gaorgot takes the fuel tank, whose capacity is 15 l.

 

Before the front spar of the fuselage below are attachment points of the chassis. The front frame serves as a fire wall, it mounted hinge assemblies pedals and foot control. On the other side of the firewall is placed drain valve, fuel filter and check valve.

 

At the junction of the frame side members and front mounted engine mount attachment points. Motorama is a frame of welded pipe diameter hromansilevyh 2,2 cm. Fixing the engine to the engine mount by means of rubber buffers. The motor is completely closed lower and upper fiberglass hoods.

 

Plumage

 

Each half-wing center section is made up of transverse and longitudinal framing. Trailing set represented by two spars (main and auxiliary), the front edges of the stringer and flow. As part of a set of cross-wing has reinforced and normal rib. The wing ailerons - plane type. All surfaces are covered with canvas wings.

Horizontal tail in "Argo-02» presented the elevator and stabilizer. The latter consists of two spars and ribs arranged diagonally, thereby providing high torsional stiffness. The elevator is composed of two overlapping parts. Each of them consists of a spar, set diagonally possessing ribs and rib flow. It is lined with plywood 1-3 mm.

 

Vertical tail fin of the aircraft is presented and the rudder. The front part of the keel has a plywood sheathing. The rear fuselage bulkhead is joined to the rear spar. Rudder is structurally similarity to the elevator and aileron. The operating handle is fixed at the bottom of the elevator spar. To prevent entry control units of the item and traction cables covered with decorative screen. All surfaces have the fabric covering of feathers.

 

Chassis

 

The aircraft is a two-wheeled main landing gear spring type. Wheel size is 300x125 mm. Steel springs attached to the fuselage on each side by means of several bolts and steel plate. Tail strut is also made of steel. Attaching it to the fuselage accomplished by screwing two bolts bearing cup, which is part of the tail support.
