Paper airplane in different ways.

Now you will learn many ways to make an airplane out of paper, until this day, I personally knew two ways, and you?

A paper airplane (airplane) is a toy airplane made of paper. It is probably the most common form of aerogami, one of the branches of origami (Japanese paper folding art). In Japanese, such a plane is called kami hikoki (kami = paper, hikoki = plane).

This toy is popular because of its simplicity - to make it easy even for a beginner in the art of folding paper. The simplest airplane requires only six [source not specified 226 days] steps for complete addition. Also, a paper airplane can be folded out of cardboard.

History of Paper Aircraft

Scientists believe that paper began to be used to make toys 2000 years ago in China, where the manufacture and launch of kites were a popular form of hanging out. Although this event can be regarded as the source of modern paper planes, it is impossible to say with certainty where exactly the invention of the kite occurred; as time progressed, more and more beautiful designs appeared, as well as types of kites with improved speed and / or lifting characteristics.

The earliest known date for the creation of paper airplanes is 1909. However, the most common version of the time of invention and the name of the inventor is 1930, Jack Northrop is a co-founder of Lockheed Corporation. Northrop used paper airplanes to test new ideas in the design of real airplanes. On the other hand, it is possible that paper planes were known back in Victorian England.

Types of Paper Airplanes

There is an unlimited [source not specified 226 days] number of types of paper airplanes that fly differently, maintain altitude and land.

Traditional

This type of airplane develops in just 6 stages, and if you do not follow the instructions for determining the center of the sheet, then in 5.

Use a rectangular piece of paper, such as A3, A4 or Letter (preferably A4 or Letter).

  1. The main fold is done as follows: with the short side of the paper toward you, fold the left or right edge of the paper so that it coincides with the opposite edge, and smooth the fold.
  2. Unfold the paper and fold the upper left corner so that it touches the main center fold, then repeat this procedure for the upper right corner.
  3. Bend the formed corner along the line where the edges of the previously bent corners end so that the sides by which these corners touch the central fold are inside.
  4. Repeat the steps described in paragraph 2, but now the sides of the corners from above should not reach the central fold slightly, that is, go obliquely, while they should not completely cover the previously folded triangle.
  5. Bend the small looking corner so that it holds the corners you folded.
  6. Now bend the airplane in half with this triangle outward, bend the sides to the main fold and launch.

DC-03

There are many people who claim to have made The World's Best Paper Airplane. An example is the DC-03 model, which has large glider wings and, possibly, one of a kind with tail plumage. There is no international federation of paper aircraft manufacturing, therefore, these statements are not amenable to official verification of accuracy.

Aerodynamics

Although the DC-03 model has wings, the holder of a record registered in the Guinness Book of Records, Ken Blackburn does not agree with the decision of its creators to add tail feathers to a paper plane. An explanation of the aerodynamics of paper airplanes, posted on his website, proves that the tail is simply not needed. Blackburn uses a real B-2 Spirit bomber such as a flying wing as an example, confirming the assumption that the weight distributed over the front of the wing makes the aircraft more stable.

Independently of it, in 1977, Edmond Hui developed a paper plane similar in shape to a stealth bomber based on hang glider aerodynamics and named it Paperang [3]. The only one of all paper airplanes, it has really working aerodynamic surfaces and long narrow wings, and its design allows you to change each shape parameter of the aircraft. In 1987, the book Amazing Paper Airplanes was released about this aircraft, and in 1992 it was the subject of several newspaper publications. Paperang cannot be used in most paper aircraft competitions because of the use of paper clips, but with good stability it has an exceptionally large coefficient with a relative planning distance of more than 12 (that is, if a plane loses 1 m in height, it flies more than 12 m horizontally).

Although light paper planes are thought to fly farther than heavy, this statement is disputed by Blackburn. Blackburn's airplane, which broke the world record more than 20 years ago (in 1983), was developed under the assumption that the best aircraft have short wings and are “heavy” at the time of the launch phase, when a person throws them into the air. Although longer wings and less weight would help the airplane seem to achieve longer flight time, such a paper airplane cannot be thrown high. According to Blackburn, “in order to achieve maximum altitude and a good transition to the planning flight, the throw must be carried out with a deviation from the vertical of not more than 10 degrees” - this shows that the speed of the airplane necessary for a successful throw must be at least 100 km / h.

Competition

In 1989, Andy Chippling founded the Paper Aircraft Manufacturing Association, and in 2006, the first paper airplane launch championship was held. Competitions are held in three disciplines: the longest distance, the longest planning and aerobatics.

World records

Numerous attempts to increase the time spent by a paper airplane in the air from time to time lead to the taking of next barriers in this sport. Ken Blackburn held the world record for 13 years (1983-1996) and again received it on October 8, 1998, throwing a paper airplane in the room so that it lasted 27.6 seconds in the air. This result is confirmed by representatives of the Guinness Book of Records and CNN reporters. The paper airplane used by Blackburn can be classified as a glider.

Competitions are held to launch paper airplanes called red bull paper wings. The last world championship was held in Austria. They are held in three categories: "aerobatics", "flight range", "flight duration".
