Brief introduction of paper airplane manufacturing method

The manual manufacturing process of folding aircraft is shown in the following figure:

1, prepare a rectangular origami first. You can use any color you like.

2. Fold the rectangular origami vertically from the middle, not horizontally.

3. after 3.step 2 is folded in half, there will be a middle line in the middle. According to this center line, the two corners under the rectangular origami are folded inward to form two triangles.

4. After the third step of folding, turn the origami upside down and fold the lower corner upwards to form a triangle.

5. Fold the lower two corners inward according to the midline to form two triangles.

6. Fold the shape folded in step 5 in half from the middle.

7. Fold one side to the other and spread the wings of the plane. It's done.

8. If you want your paper plane to fly faster and farther, you can prepare a paper clip. Clip the paper clip near the nose, and the weight will help it fly further!

A paper plane is a toy plane made of paper. Probably the most common form of aviation origami, it belongs to a branch of origami. Because it is the easiest type of origami to master, it is deeply loved by beginners and even masters.

Principle: The power of paper airplane flight comes from the kinetic energy when it is released. After flying, if the height of the plane remains the same, the air resistance will gradually slow down the speed of the plane, and the paper plane will exchange the potential energy of gravity for the kinetic energy of progress.

Therefore, we see a gliding trajectory. Theoretically, the wing of a good paper plane has a good lift-drag ratio, but even a flat wing can fly far, where the wing hardly produces lift. On the other hand, if the high-lift wing is not properly controlled, it will suddenly rise at a large elevation angle and then stall. Therefore, discussing the flight principle of paper airplanes should be divided into two categories.

One is like an arrow, flying by the kinetic energy of the hand. The throwing strength of this kind of aircraft is proportional to the flying distance.

The second glides by the lift generated by speed, just like a glider. Even if the aircraft is released vertically, it can generate lift by kinetic energy at the expense of gravitational potential energy, and then quickly glide horizontally.
