Four paper planes in China.

The four kinds of paper airplanes in China are kite spacecraft, bean horn, lantern and goldfish lamp.

1, harrier flying boat

Kite-flying boat is the most representative paper plane, which is made of thin bamboo tube as handle, sewn with woven surface and bonded with cardboard. Kites fly in the wind. With a little wind, they can soar in the sky.

2, bean speakers

The bean whisperer is in a wooden box full of sand, which contains all kinds of seeds. During the flight, the pull rod will make the sand in the box play all kinds of wonderful music, which is exciting and pleasant.

3. lanterns

Lanterns have all kinds of extraordinary splendour, usually supported by colored paper and base, which can effectively protect the torch inside and make it emit beautiful light.

4. Goldfish lamp

The goldfish lamp, sometimes called "goldfish princess", is a paper plane. It is made of colorful pieces of paper, cut out the shape of goldfish, hung on a hanger, filled with oil residue and equipped with candles.

The flight principle of paper airplane;

The material of paper plane is an important factor affecting flight. Paper with rough surface has great friction resistance with air. Too heavy paper needs more buoyancy. Paper planes made of these papers can't fly far. Therefore, the paper plane made of smooth and good texture paper has better flying effect, such as commonly used printing paper or advertising paper.

Different folding methods will also affect the flight distance of paper airplanes. In order to keep the balance of the fuselage, when folding the plane, the wing can be folded up slightly and the tail can be tilted up, so that during the flight, the air will push down the paper plane, so that it can fly more smoothly. At the same time, the larger the wing area of a paper plane, the greater the buoyancy of flying in the air and the longer the flight time.
