How were rockets propelled in ancient times? Some of the fireworks in the sky are based on the same principle, right? Wouldn't it be a musket if you left a port to fire the gunpowder? How do you load the gunpowder? Ancient China (Wandu) was the first to think of flying

Knowledge point: Wandu's flight to the sky is an allusion to a story about an official named Wandu in the Ming Dynasty of China, who, in order to realize his dream, sat on a chair strapped with 47 rockets with a kite in his hand and tried to fly into the sky, only to be crushed to pieces by the fall. It mainly illustrates the hope of ancient people who wanted to fly to the sky.

Mandu

Jets) mentioned that "around the end of the 14th century, a Chinese official whose title was Mandu, but whose name was not recorded in writing, and who was therefore called Mandu by the later generations, loaded 47 of the largest rockets that could be purchased at that time on the back of a chair. He tied himself to the front of the chair and held a large kite in each hand. Then he told his servants to light the 47 large rockets at the same time, with the intention of using the power of the upward propulsion of the rockets, coupled with the upward force of the kites to fly above. His goal was the moon!"

The story of the Ming Dynasty man Wando is not well documented in China's ancient literature, but the scene at the time is still as thrilling and awe-inspiring as it is today, more than 600 years later.

According to the record, Wando was a person in the early Ming Dynasty and was originally a carpenter. Since he liked to study skills and was especially obsessed with technological inventions, he improved many of the swords, guns, carts and ships in the army at that time after joining the army.

Wandu's skills were discovered during the Ming Dynasty's war with Wala. General Banbei of the Ming Dynasty, who was also very knowledgeable about weapons manufacturing, believed that it was because of Wando's improvements to weapons that the war was fundamentally won, so he petitioned the court to allow Wando to serve in the Bureau of Weapons. At that time, gunpowder, one of China's four great inventions, had already made its military debut, so Wando's future should have been bright.

But unfortunately, General Banbei, who was a good friend of Wandu, was a straightforward man and never tended to favor others. He was dismissed from his post for offending treacherous officials such as Li Guangtai, the right middleman, and was imprisoned in a deep valley in the upper reaches of the Rejecting Horse River.

In order to rescue his friend General Banbei from the mountains, the clever Wandu decided to build a "flying bird". However, due to other factors, the general was killed by his political opponents, and the plan to rescue him was foiled. The loss of his confidant makes Wando disgusted with the officialdom and the life of the world, and he begins to plan his escape from the officialdom and the life of the world, and decides to go to the moon to live.

At that particular time, when mankind's understanding of the natural world was very limited, Wandu, who was a carpenter, even made a very detailed scientific theoretical calculation report, thinking that according to the rocket technology at that time and with the help of the kite principle, he would be able to fly to the moon within a certain period of time. In the thinking world of this idealist, there is no human heart on the moon ......

In order to realize his own will, and also to realize the last wish of General Banback, Wando began to study the "Rocket Book" left behind by the general intently, and gave it a refinement with his own knowledge. He carefully read Banback's Book of Rockets, built a variety of rockets, and then drew the figure of a flying bird, which all the craftsmen made according to the drawing ......
