What is a glider? How to make a glider yourself: drawings, photos

The desire to fly through the air was in people's minds, it seems, always, it was this that prompted scientists to create many wonderful flying machines, but not all of them were safe, could fly for long distances. Among them - and such an amazing device, as a glider, which is relevant to this day. He gave the beginning to the whole sport, within which competitions are held. Many have heard of him, but they have no idea what he is.

What is a glider?

This is a kind of non-motorized aircraft, whose weight is much heavier than air. Movement in it occurs under the influence of its own weight. The glider makes its flight using the aerodynamic force of the air flow on its wing. It seems to float in the air. There are various models of this device: by the number of seats - single, double and multi-seat; On purpose - training, training and sports. Glider motor Is absent, this is the simplest aircraft.

For take-off, a towing aircraft is used, which anchors it to its side with a rope. After the towing machine is lifted, the glider also flies into the air. Then they unhook the cable, the device flies in solitude. Many people say that the flights on the glider are simply magnificent, because everything happens in silence, without the annoying hum of the engine. After the novice recognizes in practice what a glider is, he wants to make flights on it again and again.

There are two variants of flights on this device: flying and planning. Planning is the flight of a glider with a drop that is very similar in sensations with a rapid descent on a sleigh or on a cart on a steep slope. Hovering involves the use of a lifting force, which is created by the air flow and supports the aircraft while traveling in the air.

A bit of history

It was the flight on the glider and revealed to mankind new possibilities of soaring in the air, because before the invention of the aircraft was still very far. These aircraft did not previously have either booths for pilots or a retractable landing gear. In some models, the pilot simply lay on the platform or controlled the aircraft, standing on his hands, with the help of movements of his own body. Of course, this caused some inconvenience during the flight. These aircraft were able to remain relevant at the present time.

Many fans are thinking about how to make a glider with their own hands. It would be nice to have such a device in its arsenal for personal flights. This invention will be very pleased children and find it a good toy. A flight on a glider of real size can give a lot of wonderful sensations of easy floating in the air.

Choosing the right model

Homemade apparatus must certainly have some important qualities that can be determined when studying the appropriate option in the store.

What will the glider look like? A beginner in this business often finds it difficult to achieve the correctness of the design, which is why it is so important to follow the general rules.

Those who have a minimum of experience in the design, it will be difficult to make a model, so it is recommended to pick something light, but possessing no less elegance than the purchased analogs. There are only two basic designs of this aircraft, for the creation of which no special effort and cost is required. It is for these reasons that they will be the most optimal choice.

The first option is based on the principle of the designer, he assembles and soars into the air right at the site of testing.

The second option is prefabricated, has a holistic design and is resistant. His creation - the work is quite painstaking and difficult. Not every glider is able to make this.

Glider drawing

At the initial stage it is necessary to make calculations and carefully think over everything. For those who want to make a glider with their own hands, the drawings The finished plan needs to be viewed. It is also necessary to determine in advance the materials that will be used in the future design.

For different models of gliders, a completely standard set of resources is needed: small blocks of wood, twine, quality glue, ceiling tiles, a small piece of plywood.

The value of the first model

The first design of the glider will be quite easy, its knots are fastened with the help of usual office gloves and glue. It is for this reason that it is not necessary to follow the accuracy in the design. It is necessary to adhere to several basic rules:

• The total length of the airframe should not exceed 1 meter;
• The magnitude of the wingspan is a maximum of one and a half meters.

The remaining details are at the discretion of the glider.

Format of the second model

It's really worth thinking about the quality of the model. It is very important that all the details of the homemade aircraft are calculated to a millimeter. The glider drawing should correspond to the created model, otherwise the structure will not swirl into the air. This model should have the following parameters:

• The maximum length of the aircraft is up to 800 mm;
• The width of the wing span is 1600 mm;
• Height, which includes the dimensions of the fuselage and stabilizer, is up to 100 mm.

After all the necessary quantities are clarified, we can safely proceed with modeling.

Training is half the success

Before you start designing real aircraft, you can train and build a glider made of paper. You can make it from a small paper sheet and a match, it will fly perfectly. You just need to adjust a small weight of plasticine on the nose of the model. For this simple design, you will need a sheet of paper, scissors, matches, a piece of plasticine.

To begin with, you need to cut out the body of the airframe by template, and then bend the wings along the dotted line upwards. Next, gently stick the match on the inside of the model so that the match head protrudes from the nose of the center of the wing and does not have protrusions from behind. After the glue dries and the match is fixed, the glider adjustment process begins. It is necessary to select a weight for it from plasticine in such a way that it regulates the flight process. This balancing is attached to the edge of the match.

A simple type of glider

The basis for the glider (its wing-shaped part) is cut from the ceiling tile. After that, rectangles of a similar material are created. This is done in such a way as to suffice for all the details: the wing should measure 70 x 150 cm, the horizontal stabilizer - 160 x 80 cm, and the vertical - 80 x 80 cm. It is necessary to cut out the main parts extremely carefully.

Perimeter should be turned over with toilet paper, so that everything was extremely smooth and there was no chipping. Each narrow and thin edge should be rounded, so you can give the design a little elegance, its aerodynamic properties will also improve. Nerves can be created from simple chips, only carefully grind and give them the desired shape in advance. After all these manipulations, you need to gently stick a piece of wood to the middle of the wing in such a way that it does not go beyond the edges. The main part is almost ready.

Now we need to take up the preparation of the glider body, this design is quite simple and consists of a thin stick and small stabilizers. Rounded squares must be glued together, so that some kind of letter "t" appears in the three-dimensional dimension. It is attached to the tail part. With the help of such manipulations, you will make a frame, you will have to attach everything with the help of usual office rubbers. To help the beginning designer come the drawing of the glider, relying on which, everything can be done qualitatively.

Complex aircraft model

Create a children's glider will not be difficult for beginners. But more serious models require special efforts and much more time to design. Therefore, people who are wondering how to make a glider Independently, it is worth studying the process of building an aircraft in more detail. This will help to create a reliable design. Having a ready model, beginners will be able to assess in practice what a glider is, what advantages it has.

Toy model with a small motor

The fuselage of this model is made of finely-cut matches and pasted with plain paper for cigarettes. A piece of plasticine for adjustment fits into the nose of the model. The wings, stabilizer and keel are cut out of dense cardboard paper. Everyone who knows what a glider is, can embrace doubt when in his hands this "zagulina" turns out to be. However, the work is not yet complete.

Now it remains only to spread the cardboard wings and fix on the nose a little plasticine. After that, you can in practice check how this model makes flights.

The possibilities of this match design are very limited, it makes flights with a drop, in the air it can require constant adjustment. It is much more interesting to launch gliders in the air, capable of independently floating in the air, so you can additionally make a rubber motor. The production of this important detail takes no more than half an hour. To do this, it is necessary to carefully make small depressions in the fuselage from the matches, where the front bearing of the screw and the rear hook will be inserted. Both of these parts are made of ordinary soft wire. The latter need to be gently squeezed by the thread only in the places of its junction with the fuselage. These compounds are carefully smeared with glue.

After this, you need to scribe a motor screw with a knife from a rod, the length of which is 45 mm, the width is 6 mm, and the thickness is 4 mm. At the center of the screw, you need to pass a wire axis, the end of which is crocheted for a future rubber motor. Two threads, stretched from the clothesline, can be used for a rubber motor, they should be wound by 100-120 turns. The device with such a simple engine will soar into the air very quickly.

After the beginner makes a glider with his own hands, the drawings are more difficult for him to seem so complicated. Good luck!
