Paper airplane in different ways
Now you will learn many ways how to make a paper airplane, until this day, I personally knew two ways, and you?
A paper plane (airplane) is a toy plane made of paper. It is probably the most common form of aerohi, one of the origami branches (Japanese paper folding art). In Japanese, such an aircraft is called Kami Hikoki (Kami = paper, Hikoki = Aircraft).
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 paper airplane can be folded out of cardboard.
Paper Aircraft History
Scientists believe that the use of paper to create toys began 2,000 years ago in China, where the manufacture and launch of kites were a popular form of pastime. Although this event can be viewed as the source of modern paper airplanes, it is impossible to say with certainty where the invention of the kite occurred; as time progressed, more and more beautiful structures appeared, as well as types of kites with improved speed and / or lifting characteristics.
The earliest known date of creation of paper airplanes should be recognized in 1909. However, the most common version of the time of the invention and the name of the inventor is 1930, Jack Northrop is the co-founder of Lockheed Corporation. Northrop used paper planes to test new ideas when building real planes. On the other hand, it is possible that paper airplanes were known in Victorian England.
Types of paper airplanes
There is an unlimited [source not specified 226 days] number of paper airplane types that fly in different ways, maintain altitude and land.
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.
A rectangular sheet of paper should be used, such as A3, A4 or Letter (preferably A4 or Letter).
- The main fold is done like this: having arranged the short side of the paper towards you, bend the left or right edge of the paper so that it coincides with the opposite edge, and smooth out the fold.
- Unfold the paper and fold the upper left corner so that it touches the main central fold, then repeat this procedure for the upper right corner.
- Bend the formed corner along the line where the edges of the previously curved corners end, so that the sides by which these corners touch the central fold are inside.
- Once again, perform the actions described in paragraph 2, but now the sides of the corners on top should not slightly reach the central fold, that is, go diagonally, and they should not completely cover the previously folded triangle.
- Fold a small peeping corner so that it keeps the corners folded by you.
- Now bend the plane in half with this triangle outward, bend the sides to the main crease and run.
There are many people who claim to have made the “Best Paper Plane in the World”. An example is the model DC-03, which has large glider wings and, perhaps, is the only one of its kind with a tail. There is no international federation of paper aircraft manufacturing, therefore these statements are not amenable to official verification for accuracy.
Although the DC-03 model has wings, the holder of the record registered in the Guinness Book of Records, Ken Blackburn (Ken Blackburn) does not agree with the decision of its creators to add tail plumage to the paper plane. An explanation of the aerodynamics of paper airplanes, placed on his website, proves that tailing is simply not necessary. Blackburn uses a B-2 Spirit type real flying-wing bomber as an example, confirming the assumption that the weight distributed over the front of the wing makes the aircraft more stable.
Regardless, in 1977, Edmond Hui (Edmond Hui) on the basis of the aerodynamics of hang-gliders developed a paper plane, similar in shape to a stealth bomber, and called it Paperang . The only one of all paper airplanes, it has really working aerodynamic surfaces and long narrow wings, and its design allows you to change every parameter of the aircraft shape. In 1987, the book “Amazing Paper Airplanes” was published about this plane, and in 1992 it became the subject of several newspaper publications. Paperang cannot be used at most paper aircraft competitions due to the use of paper clips in its design, but with good stability it has an extremely large ratio of relative planning distance - more than 12 (that is, if 1 m is lost, the plane flies more than 12 m horizontally).
Although it is believed that light paper airplanes fly farther than heavy ones, this statement is disputed by Blackburn. Blackburn's airplane, which broke the world record more than 20 years ago (in 1983), was developed on the assumption that the best planes have short wings and are “heavy” during the launch phase, when a person throws them into the air. Although longer wings and less weight would help, as it seems, an airplane to achieve more flight time, but such a paper plane cannot be thrown high. According to Blackburn, “in order to achieve a maximum height and a good transition to a flight-planning flight, the throw should be done with a deviation from the vertical of no more than 10 degrees” - this shows that the airplane speed necessary for a successful throw must be at least 100 km / h.
In 1989, Andy Chipling founded the Paper Aircraft Association, and in 2006, the first paper aircraft launch championship was held. Competitions are held in three disciplines: the longest distance, the longest planning and aerobatics.
Numerous attempts to increase the residence time of a paper airplane in the air from time to time lead to the taking of the next barriers in this sport. Ken Blackburn (Ken Blackburn) held the world record for 13 years (1983-1996) and again received it on October 8, 1998, leaving the paper plane 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.
There are competitions for launching paper airplanes called red bull paper wings. The last world championship was held in Austria. They are conducted in three categories: “aerobatics”, “flight range”, “flight duration”.
