The design of the glider, the method of making the glider

Gliders require a high lift-to-drag ratio, and there are two most important things about this: wing shape and airfoil.

The wing shape should choose a wing with a large aspect ratio, as for the sweep angle, according to the flight speed of the aircraft, the lateral stability of the glider can be improved with the sweep angle, which is conducive to improving the flight quality.

Airfoil selection is still to choose a high lift-to-drag ratio airfoil, this has an airfoil library, you can check, of course, you can also calculate it yourself.

I don't understand what the landlord said about the bumps.。。。

There are also anti-angles and geometric twist angles on the wing. The first angle, generally 2 to 4 degrees, is conducive to the stability of the aircraft; The second angle, which is conducive to the lift-resistance characteristics of the aircraft, has a different angle of attack between the wing root and the wing tip chord, which can alleviate the premature stall of the wingtip at a large angle of attack.

In order to reduce drag, winglets can also be designed at the tips of the wingtips, which can reduce the induced drag and facilitate gliding.

There is also an installation angle, the gliding wing has an angle of attack, if there is no installation angle, the angle of attack of the fuselage is the same as the wing, the drag increases, but the lift does not change significantly. Therefore, the installation angle is designed to reduce the angle of attack of the body during flight and reduce the drag.

Basically, there are many details about these large things, and it is not easy to explain, so let's take a brief look at aerodynamics, structural mechanics, and flight mechanics. Does the landlord want to build his own plane?

Upstairs is already detailed.

1. First of all, prepare the tool raw materials: cardboard, pen, stapler, ruler, scissors.

2. Fold the cardboard in half first, and be careful not to wrinkle the cardboard, as shown in the figure below

3. Then use a ruler to draw a sketch of the glider, as shown in the figure below

4. Then use the stapler to nail a grid on the head of the glider, as shown in the figure below

5. Then cut it off with scissors, as shown in the figure below

6. After opening it, the prototype has collapsed and returned to the meridian, as shown in the following figure:

7. Then we fold its wings inward with our hands, as shown in the figure below

8. The same tail should also be folded, as shown in the figure below

9. Finally, you can answer some patterns on the plum shirt, as shown in the figure below

Do you want to be Kidd's glider? It's not impossible, first of all, you have to make the glider foldable, and remember, Kidd's glider can be worn directly on clothes, so the carriage of the glider must be shrunk to a very small size, the fabric of the glider must fit the clothes, as for the power, it is not so necessary, and there are equipment and switches that can be stretched in an instant, in fact, I personally think that the spring on the wooden clothespin can be used.

That hang glider is too small. If you fly, you will be planted directly. And it's hard to find such a light material, and even if you do, it will cost you to death. Of course you can make a model.

I'll just talk about the overall structure A tripod you can see at the beginning, not much to say, just one sentence: it must be wide! If it's too narrow, you won't be able to take off until you run 10m s (not to mention that you can't necessarily run that fast)!

There should be a flat stove balance rod behind the tripod, just like the rod behind ***! Put a weight-adjusting device on the back to adjust the center of gravity to avoid stalling.

Then there is the landing gear below, the landing gear and tripod (the one that fixes the wings) must be welded to death, and it is not fun to drive! Remember! Don't lose your life the first time you play!

The tripod should be connected to the safety rope and wrapped around the waist to prevent people from being overwhelmed by the glider when landing, and may be seriously injured!

In addition, let's talk about take-off, it is recommended to take off on the top of the building, at least the tenth floor (I definitely don't mean to hurt you, the lower the take-off is more dangerous), if you can only take off at a lower place, remember to run hard.

After jumping off the roof, quickly pull up the glider, which should automatically turn to a smooth gliding state after a rapid drop of 2-3 seconds. Then there is the adjustment of direction, tilting left, while pulling up is turning left, and vice versa. (similar to the aileron turn of an airplane) It is recommended that you play flight simulation first, and then fly, or that sentence, it is not fun to give your life!

There can't be too many other buildings near the high-rise buildings that take off (in fact, there are hillsides), and there must not be a road underneath! It's best to look for a hillside like a cliff, it's cool to fly!

That's all there is to say, strongly despise the one upstairs, and the product is still a concept product (even production hasn't even started!). Also, he copied the manual, which I originally copied!

Finally, now a plane is only a few thousand dollars, and you say that tens of thousands of them are powered gliders, which novices can't fly.

The steps for the glider folding method are as follows:

Cute Glider: Fold the jam in half. First fold the square paper in half along the central axis, and then fold the folded paper in half along the central axis, the same practice on both sides, and then fold it in half along the central axis in the same way, and then fold it in half in the opposite direction in the same way, folded into a rectangle.

Fold out the glider basic shape. Then fold the paper 1 4 in half, fold the paper in front 1 4 outward, and then fold the paper in half along the central axis to stuff the excess paper. Pinch out the rear wings. Finally, fold it in half outwards along the central axis, and then pinch out the rear wings, so that the glider is folded.

Spread your wings glider. Fold out the basic shape of the glider. First, fold and fold in half along the diagonal, and pull the upper and lower layers back to make a double water chestnut.

Fold the separated corners in the middle of the fold upwards respectively, fold a small triangle first, and then keep folding up to the bottom along the size of the small triangle to the bottom, and fold it upwards.

The body of the folding glider burns the rock mass. Fold the left and right corners that have just been separated, fold the remaining part of the section along the middle line, and flip the whole figure horizontally without moving the left and right corners, and fold up along the creases just now, and spread out the left and right corners. Finally, fold the entire tip of the tip down along the middle line to create the sharp corner.

Fold the tail of a glider. After laying the plane flat, fold the tail and the glider is folded.

Hello, it is a pleasure to serve you and give you the following answer: the best shape of a glider is a stable, aerodynamically efficient airfoil. Such an airfoil can effectively convert the air flow into the propulsion force of the glider, so that the limb glider can achieve the best flight effect.

The steps to solve this problem are as follows:1First of all, it is necessary to understand the basic principles of gliding, including aerodynamics, airfoil design, flight control, etc.

2.Then, according to the purpose of the glider, the optimal airfoil shape is determined. 3.

Next, it is necessary to design the optimal airfoil based on the principles of aerodynamics. 4.Finally, according to the principle of flight control, the airfoil shape should be adjusted so that the glider can achieve the best flight effect.

Personal tip: Glider airfoil design is a complex task that requires a combination of aerodynamics, airfoil design and flight control to design the best airfoil, so that the glider can achieve the best flight effect.
