On the question of paper airplanes, what does paper airplane mean?

I went to see the landlord.

You shouldn't be a paper airplane.

It's more like a copy of the bamboo dragonfly - the paper dragonfly.

If this thing is only made of materials like A4 paper.

Just what you are now.

The cushioning effect will be gone.

Because look at your first and second chapters.

The tips of them are all hanging down.

The weight may be too high.

The third ** is not very clear.

Although it seems to have turned him inward.

This is more tenacious than the previous one.

But the area seems to be small again.

You can try to reduce the length by 1 to 3.

Then flip the tip of the wing inward.

Try it this way.

I didn't study aerodynamics.

Just according to the times when I used to be a child when I origami airplanes.

I don't know if it's useful for the way the wing is handled (but the wing side is turned up).

Paper Airplane is a social software for chatting and making friendsUsers can use the software to expand their friends and contacts in a short period of time, whether it is ** chat or greeting is very interesting, the new design of the paper airplane chat window is also more simple, can support users around the world to chat and call. In addition, paper airplanes are protected by a strong encryption service to make calls safe and secure. On April 3, 2015, the Android version of the paper airplane was tested online in the application treasure.

The main function of paper airplanes.

2. Instant sharing: Send your life to 50 random strangers, and your joys, sorrows and sorrows will be shared from now on.

3. Meet the unknown: Every message received is unknown, and every moment can be the most wonderful chance encounter.

4. When the application asks for camera permission, you must choose to allow, so that you can use all the functions of Li Xiang without affecting it.

Because the hovering paper airplane makes use of the principles of biomimicry. Eagles can hover for long periods of time without flapping their wings in the air, using updrafts, and the same is true for paper airplanes.

According to Bernoulli's principle in fluid mechanics, the air flow velocity near the push plate (above the wing) will be faster than the air flow velocity under the push plate (under the wing). As a result, the rising air currents hold up the paper airplanes like eagles.

The upper surface of the paper airplane is slightly convex upward, so that when flying, the air velocity on the upper surface is greater than that on the lower surface, so that the upward air pressure is greater than that of the upward one, so as to obtain greater lift.

It is possible to fly, and the flight path made of paper is a parabola.

The practice regarding paper airplanes is as follows:

Fold the white paper in half along the middle, then fold each side in half. Make the top three corners and fold them down along the middle edge. In the same way, fold both sides again. Fold the extra triangles up. Just fold out the wings on both sides.

Prepare a sheet of A4 size cardboard and fold it twice horizontally along the centerline. When opened, fold vertically to a quarter length. Folds diagonally along the upper center point of the medial side, the left and right sides, respectively.

Fold the angle that appears after folding inward. Fold outward along the center line of the inner side to align the circle trap. Fold the outer hypotenuse to the top straight straight cavity.

First, fold the paper in half along the center line, and continue to fold the sides in half along the center line. The vertices on both sides are aligned along the previous crease, turned over, and the corners are folded in half along the midline. Align the corners of the top along the bottom line, then turn over to align the corners of both ends towards the midline.

Turn it over again, spread the top corners and align them downward. After that, the sides are folded down to fold out the wings, and such a beautiful paper airplane can be made.

Prepare materials: a quarter of A4 colored paper. Fold the 21x15 cm piece of origami in half along the long side, fold the two corners in half towards the midline to form a triangle, and fold it 2 more times.

Fold the ends outward, then fold them in half along the midline, and fold the middle part upwards. Open the middle part and press it down and fold it flat, and fold the two ends upward. Concave the middle part along the crease and fold the end up.
