The simplest helicopter. Homemade helicopter with your own hands. Homemade helicopter: step by step instructions. Other homemade devices

People have been excited about the idea of ​​flight since ancient times. They envied animals with wings: birds, butterflies, dragonflies. Any boy, as well as an adult man, will not refuse to play even with a small flying model. And many of them are wondering how to make a helicopter with their own hands.

Of course, the finished model can be purchased at the store. Moreover, options are offered in different price categories and in different degrees of readiness. On request, the buyer can find a miniature car, completely ready to fly, and one that needs to be assembled from the smallest parts.

But the most interesting option will still be how to make a radio-controlled helicopter yourself.

What is needed for this

To complete this difficult task, you will need some materials. Both ordinary, for example, glue, drawings, material for the manufacture of parts, and specific ones, such as a control panel.

Often they are interested not only in how to make a helicopter, but also how difficult it is. In fact, these models are considered relatively simple. The fact is that during their construction such types of work as gluing, grinding, fitting with material are not used. The flying machine will consist of nuts, bolts and several basic mechanisms that need to be assembled into a single whole.

To assemble a radio-controlled helicopter, it is desirable to use a gyroscope. It will have to be purchased ready-made. This detail is necessary in order to correctly orient the helicopter in space, it will not allow it to roll over or fall sideways. This is especially important during the first flights, when the pilot himself is still inexperienced and is just learning to control his car. The gyroscope also helps compensate for wind pressure.

Where to begin

Before you make a helicopter, you need to pick up a diagram and drawings. Then cut out the components from the material (usually wood or plastic).

The parts are connected to each other with the help of bolts and nuts, it turns out a kind of Lego helicopter. Sometimes glue is used, but such connections may be fragile.

Engine assembly

Then proceed to the assembly of the engine. The models use batteries, which are located in the center of the body to ensure a smooth horizontal position of the machine in the air.

An axis for the screw is inserted into the power supply, screw blades are installed on it. At this stage, you should conduct a preliminary check of the interaction of the control panel with the engine of the model and make sure that all functions work correctly.

It makes sense to use a special remote control for the helicopter. In addition to the basic functions that the aircraft control allows you to perform, the helicopter control is also equipped with the ability to provide the relationship between gas and the angle of inclination of the blades. Additional channels can be used to control the gyroscope or chassis.

final assembly

It remains to assemble the model. You need to properly attach the controls, do not forget about the tail rotor. The helicopter is ready for the first flight tests, which will help correct possible shortcomings.

After that, it remains to decorate the body, and you can enjoy flying. It remains only to think in the future how to make the helicopter even faster and more maneuverable.

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. A single-seat helicopter of his own design is assembled by Dmitry Dmitriev in his garage 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 the right 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. Dmitry has not yet thought about the practical application of the helicopter, at the moment he likes the assembly process itself 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 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.
If you have an interesting hobby and want to talk about it, write or call me (

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. In a wide range of stores, various models of aircraft or copters are offered. 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 over the drive and motor to the smallest detail, make a 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 you start 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 difficult part in this design is the swashplate and main rotor, as well as the tail boom, on which the tail rotor is attached.

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 an ordinary household fan on a wheel base and run it at maximum power, then it will move along with the base in the opposite direction 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.

In modern blades of industrial and military helicopters, systems are installed into which air is pumped fully automatically 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. Therefore, a homemade helicopter swashplate is not so easy to make. 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 simpler schemes. 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, such designs are ideal 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 should choose the right materials and the necessary tools. 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, a plastic frame of two halves will suffice. 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, pulling it together and fastening 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 a tail rotor, then this is a very simple model to implement. 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 unit can be bought or made independently from an aluminum pipe and plastic crossbars.

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. The turner, miller and even a 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 apparatus. 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.

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.
