Methods and steps of making paper airplanes

The manufacturing method of the paper airplane comprises the following steps:

One. step

Standard A4 paper, top folded left and right, with creases; Folding the fermented product at the left and right corners along the crease; Fold down along the red dot position; Fold the sin mark in half along two creases; Fold outward along the central axis to align the wings; Retract the wing along the central axis; You're finished.

Second, the paper plane.

1. Paper airplane (scientific name: autonomous aerodynamic physical model) is a toy airplane made of paper. As long as it is made of paper, it can be called a paper plane. Origami plane is the most common form of aviation origami, which belongs to a branch of origami and is a kind of paper plane.

2. Because it is the easiest type of origami to master, it is deeply loved by beginners and even masters. Making toys out of paper is thought to have originated in China 2000 years ago, when kites were a popular recreational activity. But it's not the same as a paper plane. The earliest paper plane can be traced back to the 1980s, and was made in the west in 1909.

However, the most accepted production method was put forward by John K. Northrop (one of the founders of Lockheed) in 1930. Northrop used paper airplanes for simulation tests to discover the flight mechanism of real airplanes.

Three. Origami manual

Origami is an artistic activity of folding paper into various shapes. Origami is not limited to paper. Origami lovers all over the world use various materials, such as tin foil paper, napkins, acetic acid tablets and so on. , while observing the folding specifications.

2. Origami originated in China in the 1 century or the 2nd century, and was introduced to Japan in the 6th century, and then spread to the whole world through Japan. It is said that origami originated in Japan and Spain.

3. The combination of origami and natural science has not only become an auxiliary teaching tool in architectural schools, but also developed origami geometry as a branch of modern geometry. Origami is not only a toy, but also a thinking activity. This is a way to symbolize peace and commemoration, and it is also a way of entertainment.
