Kong Ming lantern rose to the sky because of what

It's exactly the same principle as a hot air balloon lift-off!

In fact, the flying principle of the sky lantern is very simple, that is, the buoyancy of hot air is used to make it rise, which can be explained by Archimedes' principle: when two objects are of the same volume, the one with less mass will float on the one with the higher mass, and to put it more simply, the object with less density will float on the object with higher density. When the air in the sky lantern is heated, the volume will expand, but there is only a certain amount of space (the volume of the sky lantern), so the excess air molecules will run out of the sky lantern, and the mass will decrease, and the density of the mass volume, the volume will not change, the mass will decrease, the density of the air in the sky lantern will decrease, and the sky lantern will float up!

The reason why the Kong Ming lantern "can fly" is that the fuel combustion increases the temperature of the surrounding air, decreases and rises, thereby discharging the original air in the Kong Ming lantern, making its own gravity smaller, and the buoyancy of the air to it holds it up.

The air in the fire heating lamp under the Kong Ming lantern, the density of the hot air is small, and the buoyancy is generated, which is the same as the principle of a hot air balloon.

If you don't have a fire, you can't go up.,You just need to put a Kong Ming lantern in an open place.,It's okay to say that there's no fire.,It's not good.,How do you seal helium?,And that thing is not easy to find.。。 However, the state banned Kong Ming lanterns.

Kong Ming lantern. It is a lantern released during the Chinese Lantern Festival. When the moon breaks, the lit Kong Ming lantern rises more than 1,000 meters into the air, forming a sea of light, which is very beautiful and spectacular!

The Kong Ming lantern is made of bamboo strips and paper, and it looks like Zhuge Liang's hat. Its mouth is oval, the lower side is fixed with a double cross thread, and a candle can be lit in the middle. In the past, people released Kong Ming lanterns on the Lantern Festival to bless the festival and pray for happiness!

According to legend, Zhuge Liang's Northern Expedition.

In the Central Plains, he was besieged by the Wei army in Pingyang, and the battle was fierce until the grain and grass were exhausted. Zhuge Liang was very anxious, but the message for help could not be transmitted. He had no choice but to summon people with a lamp.

He invented a lamp, hid the message for help in the lamp, rode it downwind, and then used the upward gravity of the smoke to send the lamp out.

When the lamp flew to Shu Village, the guard Jiang Wei.

Immediately send troops to rescue it. After the army arrived, it defeated the Wei army, Zhuge Liang was able to escape, and Pingyang was able to escape. In the name of merit, the Shu army named this lamp "Kong Ming lantern".

Legend has it in five generations.

907-960), Kong Ming lanterns were also used as a military communication tool. There is a Shen Qi Niang in Fujian who helps her husband fight. She used Kong Ming Lantern to transmit military contact information and won. Yang Liulang of the Song Dynasty.

also used Kong Ming lanterns to transmit information about the invasion, at the critical moment of guarding the three passes.

Defeated the invasion of the Liao army.

The people of Sichuan, Yunnan and Guizhou were often robbed by bandits. One year, the bandits came and scared people into hiding in the mountains. On the fifteenth day of the first lunar month, the officers and soldiers fought bandits, but the mountain people did not know about it.

So the people under the mountain set off to report the news. So people went home. After that, on the fifteenth day of the first lunar month, people set off Kong Ming lanterns as a commemoration.

Later, a custom was formed that every Lantern Festival, Kong Ming lanterns would be lit as a wish for happiness.

The rising power of the Hung Ming lamp comes from the density difference between the air inside and outside the lamp. When the candle inside the lamp is lit, the air in the semi-enclosed space inside the lamp is heated and heated, and the air density with high temperature is high.

The air that is lower than the temperature is less dense, so the cold air around the lamp pushes the Hung Ming lantern upwards. This phenomenon can be seen in many people's daily lives, such as the flame of a candle drifting upward, the steam in a pot drifting upward, and the sea water evaporating into clouds under the sunlight.

The legend of Kong Ming Lantern was invented by Zhuge Kong Ming in order to transmit signals. There is a candle inside the Kong Ming lantern, and the heat emitted when the candle burns causes the Kong Ming lantern to generate power and fly into the sky.

Kong Ming lantern, also known as sky lantern, is said to have been invented by Zhuge Kong Ming during the Three Kingdoms period. In that year, Zhuge Kongming was besieged in Pingyang by Sima Yi, and he was unable to send troops out of the city for help. The Kong Ming lantern flies into the sky because it is the same principle as a modern hot air balloon, in which the inside of the lamp is burned to heat and expand the air and lift it into the air.

The Kong Ming lantern was naturally invented by Zhuge Kongming, and it was invented in order to transmit military information, which is equivalent to a hot air balloon, using the potential difference in atmospheric pressure to lift off.

Kong Ming lantern.

Kong Ming lantern, also known as sky lantern, is said to have been invented by Zhuge Kong Ming during the Three Kingdoms period. Because back then, Zhuge Kongming was besieged in Pingyang by Sima Yi and could not send troops out of the city for help. Zhuge Kong Ming calculated the direction of the wind, made a floating paper lantern, tied a message for help, and escaped the danger as a result, so later generations called this kind of lantern Kong Ming lantern.

Another theory is that the shape of this lantern resembles the hat worn by Zhuge Kongming, hence the name.

The principle of Kong Ming lantern lift-off:

The specific gravity of the heated air is small, and it is lighter than ordinary air, and it will be strung on the net. The upper part of the lantern blocks the hot air that rises upward, and as long as the pressure generated by the hot air and the cold air outside is large enough to be greater than the weight of the lantern, it will go upward. Generally, when the Kong Ming lantern is raised, it needs people to help upwards at the beginning, so that the Kong Ming lantern has a rising kinetic energy to offset the initial potential energy.

Once you go up, you can go higher as the hot air increases. Of course, the best condition for Kong Ming lanterns is that there is a certain amount of breeze, but not too much wind. Otherwise, it will burn off after tilting.

There is a breeze, and you can also blow the Kong Ming lantern like a firefly, which is very beautiful.

The principle of the Kong Ming lantern is similar to that of a hot air balloon, which is the hot gas produced by combustion.

The main principle of the rise of the Kong Ming lantern is to heat the air in the lamp, so that the density of the air in the lamp decreases, so that the gas gravity in the lamp decreases, and then the total gravity of the lamp is less than the buoyancy force, so the Kong Ming lamp will rise.

The buoyancy of a gas is caused by the same as the buoyancy of a liquid. From a macroscopic point of view, it can be thought of as a buoyancy force caused by the pressure difference between the upper and lower surfaces of an object. Usually, the atmospheric pressure refers to the atmospheric stupid pressure at the same altitude, and when the altitude does not change much, because the change in atmospheric pressure is very small, it can be ignored, so the existence of this pressure difference is generally not considered, but when discussing the buoyancy of the gas, this pressure difference cannot be ignored.

The origin of Kong Ming lantern:

Legend has it that in the fifth dynasty (907 960 AD), there was a Xin Qi Niang, when her husband was fighting in Fujian, she used to use bamboo strips to tie into a square frame, paste paper, make a headlamp, and place burning pine resin on the chassis, and the lamp flew into the sky by hot air to use as a military liaison signal. This kind of pine resin lamp is called Kong Ming lamp in Sichuan. The shape of this lantern resembles the hat worn by Zhuge Liang, hence the name.

Another theory is that it is said to have been invented by Zhuge Liang during the Three Kingdoms. Zhuge Liang was besieged by Sima Yi in Pingyang, the whole army was helpless, Zhuge Liang came up with a clever plan, calculated the direction of the wind, ordered people to bring thousands of white papers, paste into countless lanterns, and then use the upward gravitational pull of the smoke to take them into the air, and a small lantern rose.

The soldiers in the battalion shouted: "Mr. Zhuge is breaking through with a sky lantern!" ”。Sima Yi took Chunchong to believe that Sen Lease was true, and led his troops to chase in the direction of the sky lantern, and Zhuge Liang was able to escape. Therefore, later generations called this kind of lantern "Kong Ming lantern".

Modern people put Kong Ming lanterns mostly for blessings. Men, women and children write their blessings with their own hands, symbolizing the success of the harvest.

1. The principle of the original eggplant of Kong Ming lantern is the same as that of a hot air balloon, which uses the buoyancy of hot air to lift the sphere into the air;

2. It can be explained by Archimedes' principle: when an object has the same volume as air, and its weight and density are smaller than air, it can fly;

3. Heat the air in the ball, and a part of the air in the ball will flow out of the ball due to the expansion of the air, so that the internal air is less dense than the outside air, so the ball filled with hot air will fly.

The buoyancy of hot air is used to lift the sphere into the air.

According to the information of Luban's home, the principle of the hole bend book lantern is the same as that of the hot air balloon, which uses the buoyancy of hot air to lift the ball into the air. When the air inside the ball is heated, a part of the air inside the ball will flow out of the ball due to the expansion of the air, so that the inner air is less dense than the outer air, so that the sphere filled with hot air will fly.

Kong Ming lantern, also known as the sky lantern, commonly known as the wishing lantern, also known as the prayer lantern, is an ancient Han handicraft. In ancient times, it was mostly used for military purposes; Modern spikes call people to put Kong Ming lanterns mostly for blessings. Men, women and children write their blessings by hand, symbolizing a successful harvest and happiness every year.

The fact that the Kong Ming lantern can fly into the air mainly shows that after the fuel in the Kong Ming lantern is burned, the air density in the lampshade decreases, which makes the gas gravity in the lampshade decrease, and at this time, the gravity of the entire Kong Ming lantern is less than the buoyancy it is subjected to.

Kong Ming lantern, also known as the sky lantern, commonly known as the wishing lantern and the prayer lantern, is an ancient Han handicraft.

In ancient times, Kong Ming lanterns were mostly used for military purposes. Modern people put Kong Ming lanterns mostly for blessings. Men, women and children write their blessings with their own hands, symbolizing a good harvest and happiness every year. Kong Ming lanterns are generally cast on major festivals such as the Lantern Festival and the Mid-Autumn Festival.

The drift of Kong Ming lanterns means that people can't control the direction of the cherry blossoms, so they can only "resign themselves to fate". Once the wind and direction are unstable or improperly set off after liftoff, the Kong Ming lantern will directly threaten the safety of aircraft, high-voltage power supply equipment, communication facilities, mountains and forests, and all kinds of buildings, and pose a great danger to the fire safety on the ground.

Another theory is that it is said to have been invented by Zhuge Liang during the Three Kingdoms. Zhuge Liang was besieged by Sima Yi in Pingyang, the whole army was helpless, Zhuge Liang came up with a clever plan, calculated the direction of the wind, ordered people to bring thousands of blank papers, paste into countless lanterns, and then use the gravitational force of the smoke to take them into the air, one by one small lanterns rose, and the soldiers in the camp shouted: "Mr. Zhuge is breaking through with a sky lantern!"

Sima Yi actually believed it and led his troops to chase in the direction of the sky lantern, and Zhuge Liang was able to escape. Therefore, later generations called this kind of lantern "Kong Ming lantern".
