According to historical records, China invented gunpowder in the Tang Dynasty, but it was not used in war at that time. Later, Yue and Feng Jisheng, officers of the Northern Song Dynasty, made a flying weapon rocket powered by gunpowder. This rocket consists of an arrow body and a shell, made of bamboo and thick paper. The cartridge case is filled with gunpowder, the front end is sealed, and the fuse is led out from the back end. After ignition, the gas produced by gunpowder combustion is ejected backward, which makes the rocket fly to the enemy camp and explode with the help of gas reaction. Although this kind of rocket is very primitive, it is no different from modern rockets in working principle.

1 16 1 year 1 1 month, when Jin invaded the Central Plains, the Southern Song army used the rocket weapon "Li Lubao" for the first time to hit the Jin army hard. In years of fighting, both Jin and Meng Zhan have mastered rocket technology. /kloc-In the 3rd century, Mongolia made three large-scale expeditions to the west.

The power of this cluster rocket is hard to say. In the Ming dynasty, rockets developed rapidly and had a complete range. In addition to single-stage rockets, there are various cluster rockets, rockets and original multi-stage rockets. At that time, rockets had become an indispensable weapon in the battle, and there were even special rocket units.

There were also attempts of manned rocket flight in the Ming Dynasty. According to historical records, at the end of 14, many brave families in Ming dynasty sat in chairs, holding 47 huge rockets and a big kite in each hand, trying to fly like birds with the help of the thrust of rockets and the lift of kites.

Although he ended in failure, he is recognized as the first person in the world who tried to fly by rocket. To commemorate thousands of families, a crater on the moon was named after him. However, although there are many kinds of rockets in the Ming Dynasty, their accuracy and power have not been significantly improved. By the Qing Dynasty, the development of rockets was basically at a standstill. Why hasn't rocket technology been further developed in China?

Experts believe that the first reason is China's long-term peace and the closed policy pursued by feudal monarchs; The second reason is that China's rocket manufacturing is mainly "empirical", and there is a lack of in-depth and systematic research on the combustion mechanism of gunpowder, the propulsion principle of rocket and the stability principle of arrow feathers, which fundamentally leads to the difficulty in greatly improving rocket technology.

Scholars believe that Mongols invaded Central Asia, West Asia and Europe in 13, and spread China's rocket technology to Europe and other parts of the world. At this time, Albert Magno of Germany first described the technology of making rockets in Europe, and Europeans used rocket weapons for the first time in the wars of 1379 and 1380.

Just as the rocket did not develop greatly in its hometown of China, it was not the European countries that used rocket weapons earlier, but Britain, which had a great influence on the development of modern European balance technology.

1807, when the British army besieged Copenhagen, Denmark, it launched a rocket developed by an Englishman, Conglev, which burned most of the buildings in the city and razed half the city to the ground in an instant. For thousands of years, the culture and technology of the Chinese nation are so colorful.
