Calculation of the side member for strength. Calculation of the side member for strength Drawings of the Argo aircraft 02

Is it possible in our time that is called a period of total deficit, independently build a plane? Tver Avian Aviators Evgeny Ignatiev, Yuri Gulakov and Alexander Abramov responded to this question in the affirmative, creating a winged single car, subsequently called "Argo-02".

The plane was successful: successfully flew at all-Union competitions of the Sla 1987 and 1989, was the first prize-winner of the regional visiting competition of amateur aircraft in Yaroslavl. He caused increased interest among amateur aircraft designers - and the developers of the Argo, and the editorial board of the Model-Designer magazine received many letters with requests more about this plane on the pages "M-K".

The secret of the increased popularity of Argo is not in designer or technological research of designers, but rather in the traditional design and technological techniques used when creating an aircraft. Developers managed to achieve a successful combination of the construction of wooden machines of the 20s and 30s and modern aerodynamic representations of the aircraft of such a class developed for many decades. This, perhaps, is one of the main advantages of the aircraft: for its manufacture, modern plastics and composites are not required, hire from high-strength metals and synthetic tissues - only a pine timber is needed, a little plywood, canvas and enamel.

"Argo" - a plane with a single-carrier wing: its frame consists of a box of the spar and a set of frenzy ribs from a pine rail. Linen wing casing, and only a wing sock that takes a torque, trimmed plywood. The fuselage is a pine farm with the same linen trim in the tail part and with plywood in the nose. The plumage is an enraged web-based lightwork tray farm. The chassis is quite a modern design - this is quite simple steel springs. The engine is originally four-stroke from the heavy motorcycle "Ural", then equipped with a lower-stroke rmz-640 with a gearbox. Such a motor even in our days can still be "getting" in the store.

However, the simplest design of the simplest materials is just one of the terms of the machine's success. In order for all these pine railings and pieces of plywood, they need to "enter" to quite definite aerodynamic forms. In this case, the authors of Argo - must give them due - they showed enviable design wisdom. For his aircraft, they chose the aerodynamic scheme of the classic free-free monoplane with a low wing location and pulling the air screw. Nowadays, against the background of a wide variety of "ducks", "tandems" and other wonders of modern aerodynamics - an aircraft type "Argo" looks even conservative. But in this is the design wisdom: you want to build an original aircraft - do the "duck", well, if you want to build a flying aircraft - choose the classic scheme: it will never let down.

However, this is not all. So that the aircraft flew well, it is necessary to properly determine the ratio of its mass, engine power and wing square. Whether the authors helped the accurate calculation, design intuition or good knowledge of the statistical data of such aircraft, it is difficult to say, but the parameters of the Argo can be considered optimal for the machine with a motor capacity of 28 liters. from. The parameters "Argo" can be taken as a sample if someone wants to build a similar aircraft. It is these ratios of parameters that provide the best flight specifications: speed, vertex, running, mileage, etc.

At the same time, stability and controllability are determined by the ratio of the area of \u200b\u200bthe wing, plumage and steering, as well as their mutual location. And in this area, as it turned out (which perfectly understood the designers "Argo"!), Almost no one invented anything better than the standard classic scheme, and the parameters are taken on the Argo directly from the textbook: the area of \u200b\u200bthe horizontal plumage is 20% of the wing area , and vertical - 10%, the shoulder of the plumage is 2.5 aerodynamic chord of the wing and so on, without any deviations from the classic design rules, to move from which, obviously, there is no point.

The aerodynamic data of the aircraft allowed even to perform the highest pilot figures on it. But the highest pilotat is not only successful aerodynamics, but also the high strength of the structure. According to the calculations of the authors and the Technical Commission, Argo could withstand the operational overload no more than 3, which is quite enough for flights in a circle and in short routes without complex evolution in the air. In short, the highest pilot of this unit was categorically contraindicated.

But, apparently, successful and calm flights "Pancake along the horizon" soon bored by the authors-pilots "Argo". The fact that the strength of the aircraft is insufficient for the highest pilotage, forgotten. The devices were replaced by deep devias, then barrels, cough ... On August 18, 1990, when performing an indicative flight on a festival dedicated to the Day of the Air Fleet, Yuri Gulakov introduced the "Argo" in the next coup. This time and the speed was slightly higher than usual, and the maximum operational overload obviously exceeded the estimated "Troika". As a result, the Argo wing was collapsed in the air, and the pilot died in front of the audience spectators.

Here it would be necessary to "read morality" about the need to comply with the rules of flights, about flight discipline and other important things. However, as experience shows, such instructions do not bring any benefit until the pilot understands that there is no place for disorders of discipline in aviation. It is a pity that sometimes it comes too late.

As a rule, such tragic cases even with all the evidence of the reasons for their causing, make them look for errors in the design and in the calculations of the aircraft. However, in relation to the design of the Argo-02 aircraft, it is not required: the car has passed exactly what was calculated for.

That is why the Technical and Flight Methodological Commission on the aircraft of the Amateur Building of the Ministry of Aviation Industry of the USSR is recommended by the Argo-02 aircraft as a prototype for self-building in amateur conditions.

Design, technology, calculations

The power supply of the aircraft is the two-dimensional two-cylinder air cooling engine of the RMZ-640 type, which through the clinorem reducer leads a double-bladed wooden monoblock air screw.

The control system of the ARGO-02 aircraft is normal. The pilot cabin is equipped with a pilot group and engine control instruments.

The fuselage of the aircraft is wooden, diagonal and enzyme construction. The spars of the fuselage are wooden rails with a cross section 18x18 mm.

Behind the cockpit, on top of the fuselage, a light girgar is mounted, the basis of which is the foam diaphragms and stringers. Gargrot is also available in the front of the fuselage, in front of the cab - it is made of wooden diaphragms and sheathing from sheet duralumin with a thickness of 0.5 mm.

Pilot cabin is trimmed with 2.5 mm thick plywood. The tail of the fuselage in the area of \u200b\u200bfixing the stabilizer is also covered with the same plywood. All other surfaces of the fuselage have a linen trim.

Through the cockpit of the pilot, there are spars of the centerlane, which are used to attach the pilot chairs to them, as well as the post of manual control of the aircraft. The chair is molded from fiberglass and covered with artificial leather.

The board of the cabin from the inside is placed on top of it - artificial leather. On the left side of the cockpit installed ore - the throttle control handle of the engine carburetor.

The dashboard of the aircraft is frozen from sheet duralumin and covered with the so-called hammer enamel. In the cockpit, it is attached to the Spanmost number 3 on shock absorbers. The following devices are mounted on the dashboard: THC, US-250, BP-10, VD-10, EURE, TE and ignition switch. Under the board there is a fuel tap, on the front side member - the filler syringe.

In the front of the fuselage, a fuel tank of 15 liters is fixed under R AR-grotto.

At the bottom of the fuselage, the chassis fastening nodes are installed in front of the front. On the front swinger, which is also a fireproof partition, the node is attached to the node of the lever pedals and the knot fixation of the foot control roller. On the other hand, the fireproof, fuel filter and drain valve are mounted on the firewall.

Motor mounting nodes are installed at the docking points of the spars with the front spline. The motor itself was welded from chromoxile (steel 30xgs) pipes dia. 22x1 mm. At the motor mounting points, rubber shock absorbers are provided to the motor. The engine is closed with upper and lower hoods molded from fiberglass. The screw blank is glued out of five pine plates with epoxy glue and after final processing is covered with fiberglass using epoxy binder.

Wing. The basis of each wing is a longitudinal and transverse set. The longitudinal consists of a main spaner, auxiliary (wall), windshield and streaming ribs. The main side member is two-way; It consists of the upper and lower shelves made of alternating pine wheels: the root of the wing the upper shelf is 30x40 mm, in the end section - 10x40 mm; Lower shelf, respectively, 20x40 mm and 10x40 mm. Diaphragms are installed between the shelves in the area of \u200b\u200bthe rib. The spar from two sides is trimmed with a plywood thickness of 1 mm; In the root part - plywood thick 3 mm. In the root of the wing and the fastening zone of the rocking chair of the aileron, wooden bolsters are installed.

The docking nodes of the wing consoles with centroles are mounted in the root part of the wing on the front (main) spar. The docking nodes are made of steel gras 30xgs.

At the end of the spar, a mooring knot is mounted.

The frontal stringer of the wing frame is made of wooden slats with a cross section of 10x16 mm, the tail - from the rail with a cross section of 10x30 mm. From the sock and before the front side member, the wing was covered with plywood 1 mm thick. In the root part of the wing of plywood 4 mm thick, the ladder is formed.

The transverse set of the wing consists of normal and reinforced ribs. Strengthened (ribs No. 1, 2 and 3) have a beam design and consist of a shelf with a cross section of 5x 10 mm, racks and plywood walls with a thickness of 1 mm with relief holes.

Normal ribs have an enzyme construction. They are assembled from the shelves and squeezes with a cross section of 5x8 mm, assembled by savage and books.

Wing ending - foam. After processing, they are flooded with fiberglass on the epoxy binder.

Aileron - slotted type. Its frame consists of a spar with a cross section of 10x80 mm, ribs cut from plates with a thickness of 5 mm, the ribs of attack and the rib of flowing. Aeron's sock is sewn with a plywood thickness of 1 mm, and together with the spar, the firmware forms a hard closed profile, resembling a semicircular tube. Aileron sneaking knots are mounted on a spar. The response brackets of the Aileron mood are fixed on the rear side member of the wing. All surfaces and aileron, and the wing itself are covered with a web.

Plumage. The horizontal plumage of the Argo-02 aircraft consists of a stabilizer and height steering. The stabilizer of the two-servon design with diagonally furnished ribs is provided by the stabilizer high rigidity on the twist. The stabilizer sock to the front side member will be covered with a plywood thickness of 1 mm. The stabilizer can be operated in free and in the sub-sample version. To implement the second option in the rear side member, connections for fastening of the sub-vehicle. Stabilizer fastening nodes to the fuselage are mounted on the front and rear spars. High steering knots are located on the rear side member of the stabilizer; The design of them is similar to the device of the unit of the A-1 unit. Putting the stabilizer foam, flooded fiberglass.

The central part of the stabilizer is covered with plywood.

The height steering wheel consists of two parts, which to some extent duplicate each other. Each of the parts consists of a spar, diagonally delivered ribs, socks of ribs and ribs of streamlining. The nose part of the steering wheel is covered with plywood 1 mm thick. Height steering boar is fixed in the root root.

Vertical plumage consists of a keel and steering wheel. Kiel is structurally performed with a fuselage on a two-chart. The front of the keel (before the front side member) is trimmed by plywood. The rear side member is the rear spark of the fuselage.

The steering wheel of the design is not very different from the helm of height and aileron. It also consists of a spar, direct and diagonal ribs and ribs of streamlining. The front of the steering wheel to the spar is sewn plywood. Handling knots are the Wild bolts. The rotation steering wheel control lever is fixed at the bottom of the spar. On the spar of the steering wheel mounted and the mounting unit of the subsoil. All the plumage is covered with web.

Chassis. The chassis of the aircraft consists of the main chassis and tail support. The main chassis is two-wheeled, spring type. Spring curved from steel 65g; Wheels are attached to the ends of the springs. Wheel size -300x125 mm. Fastening the springs to the fuselage using a steel plate and two bolts with each side of the springs clamped with them and thus fixed relative to the fuselage.

The tail support is a strip, an arched from steel 65g, to which the reference cup is screwed down. This strip is attached to the fuselage with two bolts.

Height steering hard drive. It is carried out using the control knob (the knob from Yak-50 is used), duraluminum and intermediate rocking faces.

Aileron control is also rigid. Drive steering wheel drive - cable. It is carried out by means of suspended lever pedals, steel cables with a diameter of 3 mm and textolite rollers with a diameter of 70 mm. To exclude foreign objects in the control nodes, the floor and the control route are closed with a decorative screen.

Power point. The basis of the power plant is the engine of type RMZ-640. It is installed on a motor in an inverted position - down cylinders. On top of the engine, the upper pulley of the clinorem gear with the belt tension mechanism is located.

Fiberglass hoods are fastened with screws to self-locking anchor nuts on the fuselage and connective ring.

Kok Screw is planted on a duralumin ring and enshrined with screws. COP is made using fiberglass shut-off on epoxy binder.

Fuel system. The fuel system includes a 14 liter fuel tank, fuel pump, fuel filter, check valve, fire crane, drain crane, tee and pipeline system.

The fuel tank is welded from a food aluminum sheet with a thickness of 1.8 mm. At the bottom of the tank there is a consumable container in which the consumable and drain fittings are welded.

At the top of the tank there is a bay neck with drainage. Inside the tank there are reported partitions to prevent foaming of fuel. The tank is fixed on two beams using a coupling tape with felt pads.

Air pressure receiver system. The PVD system consists of a PVD tube (from the Yak-18 aircraft) installed on the left plane of the wing, dynamic and static pressure tubes, connecting rubber hoses, distributor and instruments.

Air propeller. The aircraft's aircraft "ARGO-02" is glued from pine plates on epoxy resin, and then processed in templates, saved fiberglass and painted. On the plane used several screws of such a design with different diameters and step. One of the most acceptable in their aerodynamic qualities has the following characteristics: diameter - 1450 mm, step - 850-mm, chord -100 mm, static traction - 85 kgf.

Lonely Single Single Tailing Airplane with a tail wheel named Margo. Master Viktor Zhevagin. You can read about its construction. The aircraft is built based on the Argo-02.

As always using information from sites
http://www.airwar.ru.
http://ru.wikipedia.org/wiki.
and other sources found by me in the internet and literature.

Single homemade aircraft "Margo". It was built in the G.Prevazhsk Ivanovo Region Viktor Zhevagin. Raised in the air in 2015. At ran 1 place among aircraft self-building. And he takes part in the International Aviakosmic Salon "Max-2019". Airplane weight - 160 kg, flight speed - 130 km / h

The power plant is a two-stroke 2-cylinder engine of air cooling RMZ-640, which through a clinoremated gearbox leads to rotation a two-bladed wooden monoblock air screw. The aircraft management system is normal. The pilot cabin is equipped with a pilot group and engine control instruments.

Compared with the original drawings of the Argo-02 in the design there are changes, mainly by the fuselage:
1. The center is expanded to 1500 mm.
2. The fuselage is expanded on top spacers up to 600 mm.
3. 2nd and 3rd splines shifted back by 70 mm. Landing in the cab and leaving has become more comfortable.
4. With a perspective under the closed cabin, the height of the harmony is increased.
5. The root rib center is increased to 1200mm.
6. The chassis mounting brackets are installed on the front side member as in the KR-2. Spring is straight, made of a glass sheet 25 mm thick. The chassis showed itself good. Import sufficient. There were goats and plues without consequences. The glued wooden springs made was originally broken at first jogs.
7. Changed the contour of the steering wheel.
The wing is made as in the designer model, changes only in the finishes.

And now a little about his progenitor: A light single aircraft "ARGO-02", was built by self-delicate masters from Kalinina E. Rignatev, Yu.Gulakov and A.Abramov. For the manufacture of "Argo-02", ordinary pine, plywood, canvas are used. The authors are used formed by homemade scheme of a classic free-free lowlane, a simple Soviet RMZ-640 engine is installed. At the following TSA flights, the Argo-02 flights showed that Kalininian homemade flies better than some solid apparatus with imported engines.

"ARGO-02" is a superhigh training free-standing unit of a classic wooden design with a free-free tail plumage. The plane has a chassis of a spring type with a tail support.

The fuselage is a wooden, deseer-proof construction, with spars of wooden rails with a cross section 18 x 18 mm. Behind the cabin, on top of the fuselage, - light Gargrot, the basis of which is the foam diaphragms and stringers. Gargrot is also available in the front of the fuselage, in front of the cabin, it is made of wooden diaphragms and shelving of sheet duralumin 0.5 mm thick. Pilot cabin and tail of the fuselage in the area of \u200b\u200bfixing the stabilizer are trimmed with a plywood 2.5 mm thick. All other surfaces of the fuselage have a linen trim.

According to the calculations of the authors and the technical commission, the operational overload from Argo-02 was equal to 3, which is quite enough for flights in a circle and short routes. The highest aerobatics of this device is categorically contraindicated. Amateur aircraft designers should not be forgotten ...

On August 18, 1990, when performing an indicative flight at the festival dedicated to the Day of the Air Fleet, Yuri Gulakov introduced the "Argo" in the next coup. This time, the speed was slightly higher than usual, and the maximum operational overload, obviously, much exceeded the estimated "Troika". As a result, the Argo wing was collapsed in the air, and the pilot died in front of the audience the audience.

Is it possible to build an airplane in our time? Tver Avian Aviators Evgeny Ignatiev, Yuri Gulakov and Alexander Abramov responded to this question in the affirmative, creating a winged single car, subsequently called "Argo-02". The plane was successful: successfully flew at all-union competitions, was the first prize-winning review of amateur aircraft in Yaroslavl. The secret of the increased popularity of Argo in amateur aviator is not in designer or technological research of designers, but rather - in their traditionality. Designers managed to achieve a successful combination of methods of designing wooden machines of the 1920s and 1930s and modern aerodynamic calculations of aircraft of such a class for many decades. In this, perhaps, one of the main advantages of the aircraft: for its manufacture, modern plastics and composites, hire from high-strength metals and synthetic tissues are not required - only a pine timber, a little plywood, canvas and enamels are needed.

However, the simplest design of common materials is just one of the concerts of the machine's success. In order for all these pine rails and pieces of plywood "flews," they need to "enter" into certain aerodynamic forms. In this case, the authors of the Argo - must give them due - they showed enviable design. For his aircraft, they chose the aerodynamic scheme of a classic free-free low-flame with a pulling air screw.

Nowadays, on the background of a wide variety of "ducks", "Tandems" and other wonders of modern aerodynamics, the aircraft of the Argo type looks even conservative. But this is the wisdom of the aircraft designer: you want to build a successful flying plane - the classic scheme - it will never let down.

However, this is not all. In order for the aircraft well flew, it is necessary to correctly determine the ratio of its mass, engine power and wing square. And here the parameters "Argo" can be considered optimal for the machine with a motor of only 28 hp.

If someone wants to build a similar aircraft - the parameters of the "Argo" can be used for the sample: it is precisely that their ratio provides the best flight characteristics: speed, sampledness, running, mileage, etc.

At the same time, the stability and controllability of the aircraft are determined by the ratio of the area of \u200b\u200bthe wing, plumage and steering, as well as their mutual location. And in this area, as it turned out (which perfectly understood the designers "Argo"!), Almost no one invented anything better than the standard classic scheme. Moreover, for "Argo", the parameters are taken directly from the textbook: the area of \u200b\u200bthe horizontal plumage is 20% of the area of \u200b\u200bthe wing, and the vertical - 10%; The shoulder of the plumage is 2.5 aerodynamic chord of the wing and so on, without any deviations from the classic design rules, to move from which, obviously, there is no point.

Although aerodynamic data allow the aircraft to perform higher piloting figures, but the air acrobatics is not only successful aerodynamics, but also the high strength of the structure. According to the authors and technical commission, the operational overload from the Argo was equal to 3, which is quite enough for flights in a circle and short routes. The highest aerobatics of this device is categorically contraindicated.

The amateur aircraft designers should not be forgotten about it ... On August 18, 1990, when performing an indicative flight at the festival dedicated to the Day of the Air Fleet, Yuri Gulakov introduced the "Argo" in the next coup. This time, the speed was slightly higher than usual, and the maximum operational overload, obviously, much exceeded the estimated "Troika". As a result, the Argo wing was collapsed in the air, and the pilot died in front of the audience the audience.

As a rule, such tragic cases even with all the evidence of the reasons for their causing, make them look for errors in the design of the aircraft and in the calculations. As for the "Argo-02", the car has handed over exactly so much as it was calculated. That is why the technical and light-methodical commission on aircraft aircraft of the amateur building of the Ministry of Aviation Industry at one time recommended "Argo-02" as a prototype for self-building.

"Argo-02" is a superhigh educational free-standing low-plan for a classic wooden design with a free-free tail plumage. The plane has a chassis of a spring type with a tail support.

The power plant is a two-stroke 2-cylinder engine of air cooling RMZ-640, which through a clinoremated gearbox leads to rotation a two-bladed wooden monoblock air screw. The aircraft management system is normal. The pilot cabin is equipped with a pilot group and engine control instruments.

The fuselage is a wooden, deseer-proof construction, with spars from wooden rails with a cross section of 18 × 18 mm. Behind the cabin, on top of the fuselage, - light Gargrot, the basis of which is the foam diaphragms and stringers. Gargrot is also available in the front of the fuselage, in front of the cabin, it is made of wooden diaphragms and shelving of sheet duralumin 0.5 mm thick. Pilot cabin and tail of the fuselage in the area of \u200b\u200bfixing the stabilizer are trimmed with a plywood 2.5 mm thick. All other surfaces of the fuselage have a linen trim.

Through the pilot cabin passed by the central spars, to which the pilot chair and the post of manual control of the aircraft are attached to the artificial leather.

The board of the cabin from the inside is placed on top of it - artificial leather. On the left side there is an ore - the throttle control handle of the engine carburetor.

The dashboard is frozen from sheet duralumin and covered with hammer enamel. In the cockpit, it is attached to the Spanmost number 3 on shock absorbers. On the board itself, the devices are mounted: THC, Us-250, BP-10, VD-10, EURE, TE and ignition switch, under the board-fuel tap, on the front side member - the filler syringe. In the front of the fuselage, the fuel tank is fixed with a capacity of 15 liters.

At the bottom of the fuselage, the chassis fastening nodes are installed in front of the front. On the front spangout, which is also a firewall, a node of the lever-type pedals and a knot fixation of the roller and a foot control are mounted. On the other hand, the firewall is located back valve, fuel filter and drain faucet.

Motor mounting nodes are installed in the locations of the spars with the frontsparkom. Motor itself was welded from chromoxile (steel 30gs) pipes with a diameter of 22 × 1 mm. The engine is attached to the motor through rubber shock absorbers. The power unit is closed with top and lower hoods of fiberglass. The screw blank is glued from five pine plates with epoxy resin and after final processing is covered with fiberglass using epoxy binder.

The basis of each half-layered is longitudinal and transverse kits. The first consists of two spars - the main and auxiliary (wall), frontal stringer and the ribs of streamlining. The main side member is a bobby, upper and lower shelves - from pine sections of alternating section. So, the section of the upper shelf: the root of the wing is 30 × 40 mm, and at the end - 10 × 40 mm; Lower - 20 × 40 mm and 10 × 40 mm, respectively. Diaphragms are installed between the shelves in the area of \u200b\u200bthe rib. The spar from two sides is trimmed with a plywood thickness of 1 mm; In the root part - plywood thick 3 mm. Wooden bins are fixed in the root part of the wing and the mounting zone of the rocking chair.

The docking nodes of the wing consoles with centroles are mounted in the root part of the wing on the front (main) spar. They made from the steel brand 30hgs. At the end of the spar there is a mooring node.

The frontal stringer of the wing frame is made of wooden rail with a cross section of 10 × 16 mm, tail - from the rail with a cross section of 10 × 30 mm.

From the sock and before the front side member, the wing was covered with plywood 1 mm thick. In the root part of the plywood 4 mm thick, the ladder is formed.

The transverse set of wings includes normal and reinforced ribs. The latter (ribs No. 1, No. 2 and No. 3) have a beam construction and consist of a shelf with a cross section of 5 × 10 mm, struts and plywood walls with a thickness of 1 mm with relief holes. Normal ribs have an enzyme construction. They are assembled from shelves and divosions with a cross section of 5 × 8 mm with the help of kosnok and books. The ending of the wing -penoplastic. After processing, they are flooded with fiberglass on the epoxy binder.

Aileron - slotted type with a frame from a spar with a cross section of 10 × 80 mm, a rib from plates with a thickness of 5 mm, the ribs of attack and the ribs of flowing. Sock is sewn 1 mm plywood; Together with the spar, the firmware forms a hard closed profile, resembling a semicircular tube. Snake nodes of the aileron are mounted on the spar, and the hanging brackets are on the rear side member of the wing. All the surfaces of the aileron and the wing itself are covered with a web.

The horizontal plumage of the Argo-02 aircraft consists of a stabilizer and height steering. The stabilizer is a two-chart, with diagonally located ribs, which provides him with a high rigidity for a twist. The sock to the front side member will be covered with plywood 1 mm thick. The stabilizer can be operated both in free and in the sub-versa. The second option assumes the installation on the rear side member of the assembly attachments. Stabilizer fastening nodes to the fuselage are mounted on the front and rear spars. High steering knots are located on the rear side member of the stabilizer; The design of them is similar to the device of the nodes of the A-1 plane. The stabilizer stabilizer fines, flooded floors, the central part is covered with plywood.

The height steering wheel is from two parts that to some extent duplicate each other. Each of the parts consists of a spar, diagonally delivered ribs with socks and ribs of streamlining. The nose part of the steering wheel is covered with plywood 1 mm thick. Height boiler control cable is mounted in the root part.

The vertical plumage of the aircraft is the keel and the steering wheel of the turn. Kiel is structurally performed with a fuselage on a two-chart. Its frontal part (before the front side member) is trimmed by plywood. The rear side member is the development of the rear spark floor of the fuselage.

The steering wheel of the design is similar to the height or ailer. It also consists of a spar, direct and diagonal ribs and ribs of streamlining. The front of the steering wheel to the spar is sewn plywood. The nodes of the hits are the priced bolts. The control lever is mounted at the bottom of the spar. There is also an assembled assembly assembly. All the plumage is covered with a web.

The main chassis of the aircraft is two-wheeled, spring type. Spring curved from steel 65g; It is fastened with 300 × 125 mm with sizes of 300 × 125 mm. The springs to the fuselage is carried out by a steel plate and a pair of bolts on each side, by which the spring is clamped and thus fixed relative to the fuselage.

The tail support is attached by two bolts to the fuselage of the strip from steel 65g, to which the base cup is screwed down.

1 - carburetor; 2 - check valve; 3 - fuel filter; 4 - consumable tank; 5 - Tank tube with drainage; 6 - fuel tank; 7 - fire crane; 8 - nutrition fitting; 9 - drain fitting; 10 - drain crane; 11 - Bay Syringe

1- static pressure distributor; 2-ditch hose; 3 - aluminum pipeline; 4 - Air Pressure Receiver (PVD)

Control of the height wheel is rigid, with the help of a handle (from the Yak-50 aircraft), duraluminum and intermediate rocking faces. Aeronia is also rigid. Drive steering wheel - Cable, with suspended lever pedals, steel cables with diameter

3mm and textolite rollers with a diameter of 70 mm. To exclude foreign items in the control nodes, the floor and the trail and cable closed with a decorative screen.

The power supply of the aircraft - on the basis of the engine of type RMZ-640, mounted on the motor in the turned down position - down cylinders. On top of the engine - the upper pulley of the clinorem reducer with the belt tension mechanism. Fiberglass hoods are attached to screws to self-locking anchor nuts on the fuselage and connecting ring.

The air screw is glued with epoxy resin from pine plates, and then processed in templates, covered with fiberglass and painted. The "Argo-02" used several such screws with different diameters and step. One of the most acceptable in their aerodynamic qualities has the following characteristics: diameter - 1450 mm, step - 850 mm, chord - 100 mm, static thrust - 85 kgf. Kok Screw was shot out of fiberglass on the epoxy binder and planted on a duralumin ring. Coco fastening to propeller - screws.

The fuel system of the aircraft consists of a fuel tank with a capacity of 14 liters, fuel pump, fuel filter, check valve, fire crane, drain crane, tee and pipeline system.

The fuel tank is welded from an aluminum leaf with a thickness of 1.8 mm. In the lower part there is a consumable container in which the consumables and drain fittings are welded, in the upper part - the filling neck with drainage, inside - the reporting partitions to prevent foaming of fuel. The tank is fixed on two beams using a coupling tape with felt pads.

The air pressure receiver system (PVD) consists of a PVD tube (from the Yak-18 aircraft) installed on the left plane of the wing, dynamic and static pressure tubes, connecting rubber hoses, distributor and instruments.
