The folding method of the ejection paper airplane is as follows:

1. Prepare a rectangular piece of paper. It is recommended to use A4 paper, which requires a thicker paper.

2. Fold the paper in half vertically and press the creases flat.

3. Unfold the paper, fold the left and right corners in half toward the center line, and flatten the creases.

4. Fold the left and right corners toward the center line again to form an inverted triangle, and then flatten the crease.

5. Fold the upper parts of both sides toward the middle and press the creases flat.

6. Then fold the upper parts of both sides downward so that they are aligned with the lower parts.

7. Fold the entire aircraft in half toward the center line, and then unfold it.

8. Fold the upper two corners of the paper downwards and align them with the lower creases to form a small triangle.

9. Fold the two lower corners of the paper upwards and align them with the upper creases.

10. Fold the entire airplane back in half and turn over the small triangle on top.

11. Finally, pull out a small corner from the back of the paper airplane and use it as the handle of the launcher.

The definition and types of paper airplanes

1. The definition of paper airplanes

Paper airplanes (scientific name: autonomous power aerodynamic physical model) are a kind of Toy airplanes made of paper, the earliest paper airplane that can be traced back to 1909 was made in the West in 1909. It is the most common form of aviation origami and is a branch of origami.

2. Types of paper airplanes

(1) King of the Air (airplane)

Toda Takuo, chairman of the Japan Origami Aircraft Association, created the paper airplane New world record for flight time: 27.9 seconds, 0.3 seconds longer than the original time record.

Toda Takuo called this paper airplane the "King of the Sky". It was made by folding only a piece of paper, without using glue or scissors in the whole process.

(2) Susan (Distance Machine)

The paper airplane designed by American paper airplane master John Collins was broken on February 26, 2012 and kept by Stephen Craig The 9-year-old record was 226 feet 10 inches (69.14 meters), thrown by football player Joe Ayoub.

John named the aircraft after his wife's name "Susan". Susan's broke the traditional shape of the distance aircraft. Its shape is similar to the traditional 6-step folded model mentioned above. Joe Ayew The best throw ever achieved by this aircraft was 232 feet 6 inches, which was entered into the Guinness Book of World Records.

(3) Simulation machine

Almost all paper airplane enthusiasts are studying folding methods with a more realistic appearance, so various paper airplanes that imitate the proportions of real airplanes have emerged. airplane. In order to achieve simulated appearance, it is inevitable to perform more detailed processing on the paper airplane, such as trimming the shape.
