Make a helicopter with your own hands drawings. DIY homemade helicopter

Having calculated the ninth ten, Yuri Vasilyevich Vesnin still does not calm down. In the old yard one-story house in the center of Ryazan all the time something happens. Either the restless grandfather repairs the old "Tavria", then he patches up the hut, then ... he builds a helicopter.

The turner, miller and jack-of-all-trades assembled his first aircraft when he was not yet 30 years old. All this happened in Alma-Ata. Yuri Vesnin then worked at the plant, in parallel with his main turning business, he mastered oxy-fuel and electric welding, and in his spare time he made everything little by little. I made friends with one pilot, and one day, take it and say: "You can do anything, let's make a helicopter." But to say one thing, but where to get spare parts? At one of the airfields, it was possible to get the main thing - the blades. I was going to buy those that were removed from already decommissioned cars. And before that, he studied the device of the helicopter and the theory of flight.

And the engineer at the airport demanded: “Take the exam. If you hand over, we will give the blades for nothing. Well, I passed. And the blades, by the way, turned out to be completely new, right in the package, - says Yuri Vasilyevich.

The master made the helicopter, but he never saw the sky. One pilot appeared on the horizon, from those who "only wear a uniform", Yuri his wife and became jealous. And in order to let off steam, he took and sawed his helicopter at night. The story with small aircraft did not end there, but it stopped for a long time. But "got" another industry - the automotive industry.

I honestly don't remember how many cars I made. One "Rafik" was even registered, he came to Ryazan with us. And how many "bobiks" (the common nickname for UAZ - Ed.) were - not to count. To whom they sold, to whom they gave.

The same "Rafik" has an engine and a bridge from "Moskvich", and for a helicopter it was only necessary to find blades and an engine. Everything else - with their own hands. Moreover, he taught the sons of childhood to work, so the boys had something to do.

YOUR PIECE OF SKY

During perestroika, the family moved to Ryazan. Here, an old dream of a helicopter came true. Blades can now be bought freely, but for what? Here we were lucky - the son-paratrooper had just returned from a long business trip to Yugoslavia. I spent the money I earned like this: I bought a house for four thousand dollars, and for six thousand "green" ... blades for a helicopter. The engine from "Subaru" in comparison with the blades cost a penny - they gave only a thousand rubles. Everything else was done with their own hands, as a result, an analogue of the K-26 helicopter was obtained. We flew for the first time six years ago.

We do not have permission, it is very difficult to obtain it. But we know the rules and fly only where possible - over the meadows, - says Yuri Vasilyevich. - At first, my wife only said: "Fools, you will break." But then nothing ... We slowly started, “ran”, then climbed, made a U-turn in the air, studied in general. Well, then they did what they wanted.

The car, named "Almaatinets", sits down very gently: it hangs a little in the air and smoothly descends. No work for the sake of such sensations, according to Yuri Vasilyevich, is not a pity.

Do you know how beautiful it is when you get up? You can’t see anything here, but there are lakes, villages - you can’t convey, - Yuri Vesnin shares.

But the master did not rest on this either, now, together with his son, he is already assembling the second helicopter. I started right in my yard, carefully wrapped the frame with a blanket for the winter, and when it got warmer, I took the future car to my son's garage - more serious work is needed.

Yury Vasilyevich's neighbors don't even know that he collects helicopters, you never know what he does there?

It's just amazing, such an age and he is constantly working, drawing something, developing, - says neighbor Valentina Grigoryevna. “But he certainly doesn’t interfere with us.” Drunkards and brawlers get in the way, and Yuri Vasilievich ... if only there were more of them!

A person has such an interesting hobby, and even at that age - it's wonderful! - shares a neighbor Lyudmila Borisovna. - Someone sews, someone knits, and he came up with something!

OH, GIRLS, I'LL GO!

The master was widowed five years ago, so he lives alone. Three children, six grandchildren, and no one forgets the old man. Yes, he has no time to be bored - the garage is nearby. In the yard is an old "Tavria", bought for 8 thousand rubles. Here he subdued, patched up there, as a result, the car drives as if nothing had happened. By the way, Yuri Vesnin has 62 years of driving experience. During this time, he says, not a single fine was issued. Well, at your leisure, you can go to Walnut Lake and swim. Work out on the horizontal bars there. The people are surprised, come up, ask "how old?". The answer "81" - this is last summer - no one believes, you have to show your driver's license. And they say we don't have men.

COMPETENT

Director of the airfield "Protasovo" Viktor Aksenov:

In principle, you can make a helicopter yourself. That's why he is a man, especially Russian - each of us has his own Kulibin. It is not necessary to have a special education for this. The main thing is that a person has an engineering idea, - says Viktor Fedorovich. - Another thing is that such people, as a rule, do not have the official right to fly - it is difficult to get all the documents. And there are enough craftsmen, in each region 2-3 people threaten to do such things. Especially a lot in the south of the country, in the Rostov region and Krasnodar Territory. It's in our blood.

OPINION OF ROSTRANSNADZOR

The fact that Russian craftsmen take to the air on their own hand-held units is wonderful. But how do the authorities feel about it? After all, in the sky, as well as on the road, there must be order. It turned out that Yuri Vasilievich can fly calmly, the authorities don’t care about him and his kind.

Finding homemade devices and their owner is very difficult. We inspect only at airports, and these craftsmen fly only from their garage, ”Boris Ruchkin, deputy head of the department for overseeing the state of flight safety and analyzing activities in civil aviation of the Rostransnadzor of the Russian Federation, told Komsomolskaya Pravda. - Local authorities - administration, police, prosecutor's office and state security agencies should detect and fine violators. The fine for illegal flights is a maximum of five thousand rubles. Well, how many violations will be revealed - it depends on the inspector.

Who hasn't dreamed of having their own helicopter? Probably every child and every man thought about it. After all, men are big babies. There are many different stories about helicopters. For example, a girl who carried a box with a model of this device on the subway for her husband has never received such attention from other men. Naturally, those around were not interested in the girl at all, but in this particular model.

Today you can buy almost anything. Shops offer a wide range of various models airplanes or copters. But it's easy to buy, and a homemade helicopter is very interesting. After all, here you need to come up with a design, think through the smallest details drive and motor, make the control system. This is a lot of work. Usually this is done by technology lovers or engineers in their free time. But there is information and not only about the models of this flying technique. There are quite real flying machines embodied in metal.

Today you can even meet entire subcultures of people who design, manufacture and launch such homemade aircraft and helicopters. These are real enthusiasts in this field.

First helicopter

Before making homemade devices, you need to figure out how this thing works, how it works, due to which it rises into the air.

The first helicopter was lifted into the air in 1907. For those not in the know, this happened 4 years after the Wright brothers' greatest inventors first flew their homemade flying machine.

The helicopter was created by French sky lovers. The Breguet brothers gave their aircraft the name "gyroplane". He weighed about 578 kg. The petrol engine had a capacity of 45 hp. With. The device was equipped with four rotors with a diameter of 8.1 m. Also, 8 more blades were installed on each individual screw. They were connected to each other in pairs. The helicopter also had four biplane-type rotating wings. Thus, the thrust of the aircraft structure was about 600 kg.

This is, one might say, a homemade helicopter. After all, they collected it from improvised means. As a result, he was able to rise 60 cm above the ground. The device hung above the surface for a minute.

The difference of four years between the invention of the airplane and the helicopter can only be explained by the complexity of the design of the helicopter.

Design

There are several types of copters. They are divided into types. These are single-screw, coaxial, as well as transverse and longitudinal. The first two are especially common. Let's see how these flying structures work. If you know how the apparatus works, as well as its principle of operation, then it will not be difficult to assemble a home-made helicopter with your own hands, if only there is a desire.

Single screw scheme

The design consists of a fuselage, in front of which is a cockpit for pilots. The rest of the place is designed to accommodate passengers or cargo. Fuel tanks are attached to the right and left, next to the chassis. The design also includes two gas turbine engines. Each of them has a capacity of 1500 liters. With. In front, directly above the cockpit, there are air intakes, behind the exhaust system.

The most hard part in this design - swashplate and main rotor, as well as the tail boom, on which the tail rotor is fixed.

Coaxial scheme

The components of this machine are not much different from the previous type. In industrial and military vehicles, perhaps the motors are more powerful. Also, the difference is the presence of 2 rotors. Helicopters built according to this principle do not have a control screw. However, they are equipped with a vertical stabilizer.

How and why do they fly?

If you put the usual household fan on the wheelbase and run it at maximum power, then it will move along with the base in the direction that is opposite to the air flow. This is all because of the thrust that the element creates.

The helicopter propeller performs the same function. It is the last detail that performs the main tasks of lifting the aircraft. Also, the screw makes the car move in a horizontal plane. This is one of the most complex parts of a helicopter.

Main screw

This assembly consists of a sleeve and blades. The blades can be made in the form of a one-piece metal structure or a spar, as well as skin and fillers.

V modern blades industrial and military helicopters are equipped with systems that are fully automatic mode air is pumped in if the spar is somehow damaged. In 1963, the helicopter revolution took place, and the blades of the machine began to be made on the basis of fiberglass. Today, such parts are used on most helicopters around the world. But, if there is access to the production of various elements from such material, a home-made helicopter can also be equipped with them.

In most cases, the blades were attached to the hub using hinges or various flexible elements. In the helicopter industry, a three-hinged design is especially common. It has a hinge in the horizontal plane, as well as a vertical and axial element.

During the flight of such a machine, the blades sometimes make a variety of movements. They can rotate around the horizontal axis of the screw and change their position with each revolution.

Blades and hinges

The hinges are arranged in a very strictly defined sequence at a certain distance from the center. At first there is a horizontal, then a vertical, and at the end an axial hinge.

Why all this? And here's what. The propeller blades rotate clockwise around the axis. At a position of 90 degrees, the speed at which the blades move in relation to air flows is maximum. It consists of the one with which the screw rotates, and directly the speed of the air going towards the machine.

On the opposite side, this value is minimal. It's from the air current. It would seem that such a difference in speeds cannot contribute to the rise of the aircraft into the air. But no. Since the blades are fixed to the hub by means of flexible elements, instead of tipping over the machine, it remains only to change the angle of inclination.

The process of lifting the helicopter into the sky and the flight itself occurs due to the fact that the angle of attack of the blades changes. This is synchronized with engine thrust. In order to be able to synchronize the operation of the blades and motors, the so-called automatic control of the angle of attack, or the skew element, was invented. This node has a rather complex structure. So homemade machine skewing a helicopter is not so easy to do. Although the drawings of this node exist.

DIY radio-controlled helicopters

About five years ago, radio-controlled models were a curiosity for many. People flocked to see this miracle. Today, such equipment is offered in a variety of configurations. Most people prefer ready-made kits. But there are also parts for self-production.

Getting ready to assemble

If you want to assemble a helicopter on your own, then you should start with more simple circuits. This is in most cases two rotors on one chassis. Such models have higher stability than their counterparts in the classic layout. This is ideal for those who have never flown. Also, similar structures are ideal option if you have to fly in enclosed spaces.

Before assembling a homemade mini-helicopter, you should follow the basic rules. First you need to come up with or develop a scheme. Then you need to choose the right materials and essential tool. Threads, and especially in metal, are best placed on a thread lock. This is necessary for security.

Necessary materials

To make such a flying technique, you will need plastic, fiberglass, wood, carbon fiber and aluminum. You also need an engine, batteries, blades, a rotor, a gearbox for the tail. In addition, you will need servos for control, electronic components, paint, glue and some little things.

Homemade radio-controlled helicopter in several stages

Now we will see how to make such a model from what everyone has in the garage. Assembly will be done in several steps. Let's take a look at them.

Frame

So, to get started, we need a frame. The main details and nodes will be fixed on it. This node must have high rigidity. The more rigid the structure, the better.

For hobby equipment will be enough plastic frame from two halves. Bearings and other parts will be clamped between the two parts. Then the halves need to be pulled together with self-tapping screws. If you managed to make a frame according to this principle, having pulled and fastened it correctly, you can consider that a third of all the work has already been done.

Motor

If you do not want to calculate the gear ratios and engine power for a long time using specialized programs, it is better to make the motor comply with the manufacturer's recommendations. The motor is attached to the frame. The torque will be transmitted to the clutch. To do this, additionally mount a rubber clutch.

Clutch

On a homemade helicopter with your own hands, you need to install a centrifugal clutch system. It should include a flywheel and cams, as well as a "bell". When the speed reaches the desired level, the cams will move apart and engage with it.

Rotor

If the model is designed according to the scheme with one main rotor and tail rotor, then this is very simple model for implementation. How to proceed further? An overrunning clutch must be mounted between the motor and the rotor. It is designed so that the mechanism can rotate freely by inertia.

tail boom

This part can be made of aluminum, carbon fiber or carbon fiber. Rigidity matters here. Inside the beam, you need to place a belt drive or a shaft through which the rotation of the motor will be transmitted to the rotor on the tail.

Tail Rotor Pitch Control

Homemade helicopter provides for the presence of a machine to control the tail rotor. So, you can apply long traction through intermediate rocking chairs.

Chassis

To make the device more stable, it must be equipped with a chassis. This allows you to soften the blows and prevent possible rollovers of the machine. This node can be bought or made independently from aluminum pipe and plastic cross bars.

Bonnet part

This is more of a decorative detail, although it also has a shockproof function. Suitable for making plastic. The lighter it is, the better.

Electronic system

Without a gyroscope, a receiver, batteries and servos, efforts are simply doomed to failure. A homemade radio-controlled helicopter will not take off without the above details. Electronics is also mounted in the body of a flying machine. To ensure safety, a switch and battery charge indicators can be added to the electronic part.

As a remote control, it is better to purchase a ready-made device. To assemble such a device from scratch is not for everyone. You also need to remember that the design of the aircraft should not have heavy motors or batteries. Otherwise, the car will not fly due to the large curb weight.

Making a helicopter with your own hands is a very exciting activity. But flying with him is a real art. Flights of homemade helicopters are a special sight. If you learn how to operate the device masterfully, then you will definitely cause delight among others.

Blades for helicopters

All those who regularly fly with such models know how often these elements break down. This is especially true for novice pilots. I want to play with a helicopter, but constantly acquiring these parts is not an option at all. In addition, their price is impressive.

In an hour, you can make four homemade blades for a helicopter. For manufacturing, you will need plastic cards without embossing, as well as whole blades. Whole parts will be used as a template.

One of the blades should be removed from the profile. To do this, you can warm it up on gas, and then flatten it on a table or any other object. The main thing is not to do it too hard. Then, you need to circle the template, for example, with a knife. It is necessary to cut several times without pressure, and then increase the pressure from time to time. Further, with a gentle movement, the plastic card is broken and further cut through.

So the preparation turned out. Now we need to make it thinner. To do this, you need to clean it with a sandpaper from the second third of its size. Then we move on to creating a profile. Here it is necessary to roll the rag into a roll, and heat our workpiece until soft. You need to heat from the wide side. Then, when it is already soft enough, you can put it on a roll of fabric. In order to obtain the desired profile, it is enough to press the workpiece from above with a factory blade.

Other homemade devices

Not everyone prefers a homemade helicopter on the control panel. Some technology lovers prefer to assemble quite serious cars. They look almost like real helicopters, they are just made in the majority quite handicraft. But it's still a hobby.

For example, a guy from Nigeria, who studies at the Faculty of Physics, is fond of taking apart old automotive equipment for parts and assembling a real home-made helicopter from it. The guy also develops the drawings himself.

About his next offspring, the Nigerian physicist says that he assembled the car for about eight months. This device has risen over Nigerian lands more than 6 times. The material used was aluminum scrap.

This fruit of engineering thought is equipped with a motor from a Honda car. The engine has a capacity of 133 liters. With. Seats from Toyota are installed in the back. Other components were from a Boeing that had crashed nearby.

Another homemade chainsaw helicopter became an opportunity for a prisoner to organize a jailbreak. True, its design was simple to the point of being banal. The prisoner attached a wooden screw to the chainsaw. This made it possible for a man to easily overcome more than 100 meters on such a "helicopter".

And the 82-year-old resident of Ryazan, despite his age, is fond of aviation and helicopter engineering. Turner, miller and all great master assembled his first aircraft at the age of 30. He then worked at one of the factories in Alma-Ata. There he met one pilot, and he helped him design a home-made single-seat helicopter.

Although this helicopter is already about 50 years old, the old specialist still continues to design more and more new machines. Today, with his son, he is trying to assemble another model of the device. Assembly began right in the yard, then moved to the garage.

One lover of helicopter technology also lives in Kharkov. Of course, his car cannot fly over the ground. His helicopter is equipped with an autopilot and controlled by radio. This design is characterized by the presence of an autopilot. The helicopter can fly over 200 points along a predetermined route, as well as return to the place where the device took off earlier.

Conclusion

So we learned how to make a homemade helicopter. As you can see, with the right level of skills and information, you can collect decent aircraft.

HELICOPTERS

One of the types aircraft heavier than air is called a helicopter. The source of the lifting force of a helicopter is not the wing, as in gliders and airplanes, but a large air propeller mounted on the vertical axis. By rotating a helicopter propeller (sometimes called a rotor) at the required speed, you can get enough lift to fly the machine.

The helicopter was invented by the great Russian scientist M. V. Lomonosov. Creating a theory of phenomena occurring in the atmosphere, Lomonosov was faced with the need to lift measuring instruments to the air. On February 4, 1754, he made a report on the “aerodrome machine” he had invented, and already in July it was built and tested in the form of a model.

Lomonosov's "airfield machine" had two propellers rotating around a common axis in different directions.

Modern helicopters are built according to various design schemes. On fig. 66 shows one of the types of modern Soviet helicopters. This helicopter has only one propeller (rotor) used to generate lift. The rotor is driven by an engine installed in the fuselage of the helicopter. The cockpit is located in the forward glazed part of the fuselage. Helicopter wheels, together with struts and devices (shock absorbers) that soften the shock during landing, make up the helicopter landing gear, which is used for parking and movement on the ground. At the end of the long tail boom is a small screw that prevents the entire helicopter from rotating or turns it in the desired direction at the request of the pilot.

SIMPLE HELICOPTER

Building a helicopter model is not easy, especially for beginner modellers. But you can just make a flying propeller. Such a propeller is most often called a “fly”, perhaps because when it is launched into the air, a noise is heard that resembles the buzz of a big fly.

The simplest helicopter consists of a screw and a rod - an axis on which the screw is mounted (Fig. 67).

MANUFACTURE OF "FLY"

When building a “fly”, the most difficult thing is to make a screw. It is made like this. From a piece of linden, birch, maple or alder, a rectangular bar is cut, the length of which is seven to ten times its width, and the thickness is about a third of its width (Fig. 68).

Rice. 67. Flying propeller 68. Drawing a blank for a simple "fly" helicopter

Having found the center of the bar, they drill or pierce a hole for the axis with a thick awl. Having brought the hole diameter to 3-4 mm, they proceed to the processing of the bar. To do this, on a wide plane, a semicircle is drawn with a radius equal to half the width of the bar. A circle is drawn around the central hole with a radius equal to the thickness of the bar T.

After that, with a sharp knife, sections of the bar that go beyond the limits shown in Fig. 68 bold line. As a result of such processing, the workpiece acquires the form shown in Fig. 69.

Then the most important part of the work begins - shaping the propeller blades. The blades of the finished “fly” propeller should be thin: the lighter the propeller, the better the model will fly. Blades in symmetrical sections must be given the same slope and correct form section, it is useful to reduce the slope to the ends of the blade.

Finally, it is necessary to ensure that the blades have the same weight. This can be achieved if the blades are carefully and carefully processed: the more the wood is cut, the thinner the blades become, but the easier it is to break or spoil them with a rough, inaccurate movement of the knife. Therefore, it is better to process the blades in three or four steps.

First, with a knife, you need to roughly process both blades. After that, the thickness of the blades is reduced with a rasp and a file with a large notch (bastard), while simultaneously giving the blades, in the first approximation, the correct shape in section.
The third stage consists in fine-tuning the cross-sectional shape and thickness of the blades using glass or a file that has a small notch (personal). Here it is already necessary to check whether the blades have the same weight, for which the manufactured screw is put on a wire and ensure that it is balanced in all positions. The fourth stage consists in carefully grinding the blades with glass paper - sandpaper.

Probably many have heard about the light two-seat helicopters "Berkut", which is produced in Togliatti by OOO KB "Berkut". So, on this topic of helicopter construction in Togliatti is far from being exhausted. Single seat helicopter own design collects in his garage Dmitry Dmitriev in his spare time. When asked what prompted him to do such an unusual thing, Dmitry said that he always had a craving for design and invention, and also wanted to destroy the myth that a helicopter is much more difficult to assemble than a car. According to Dmitry, several dozen people in Russia are already assembling helicopters at home, together they communicate on the Internet and share advice with each other.

01. Dmitry took the American helicopter Exec-162 as the basis of his helicopter

02. More recently, Dmitry's helicopter was fully assembled (only without the blades, which are not yet available). Dmitry tested it on the street and found some design flaws, decided to disassemble it and bring it to mind.

03. Dmitry made most of the parts of the helicopter himself.

04. The most difficult thing, according to him, is to find desired material, no one wants to work with a private person, firms usually sell materials in bulk.

05. Rear screw.

06. Engine - VAZ 2111

07. After testing, Dmitry decided to lighten the engine, remove the receiver, put a short intake pipe and a lighter muffler.

08. Central screw drive and muffler.

09. Dmitry has acquaintances in a car repair shop that modernizes engines for sports cars, where he makes complex parts.

10. Dmitry does not have a special education related to aircraft construction, he comes to everything himself, finding the necessary literature and communicating with like-minded people on the Internet.

11. About practical application Dmitry has not yet thought of a helicopter, this moment he likes the process of assembly more.

12. Some details

14. Immediately, another interesting thing was discovered in the garage - a box for underwater shooting, made by Dmitry either from a double boiler, or from a juicer.

15. In addition to assembling a helicopter, Dmitry is also fond of diving and taking pictures a little.

16. It has already taken seven years to assemble the helicopter, but Dmitry is in no hurry, he does everything thoroughly, but, according to him, "without fanaticism", not forgetting about his family.

28. Someone stamps parts for space rockets in garages, and Dmitry assembles a helicopter and dreams of his first flight.

Don't forget to click on the social buttons. networks, we will support Dmitry and wish him creative success.

We must pay tribute to the inventor - he created a working design from improvised materials. Such inventors should be united in a design bureau so that small aircraft could be revived.
The helicopter was made in 1979 in the city of Cherkasy. The entire structure is homemade, except for the engine. Details from different techniques, wooden screw. The engine from the snowmobile "Buran".
It flies at speeds up to 150 km per hour. It was tested at a height of 8-10 meters, but theoretically it can fly higher.

The first video shows a test of a homemade helicopter.
