China has always been hailed as the hometown of ancient rockets, which was made by ancient scientists via applying the counterforce produced by ignitedgunpowder. Through longtime evolvement combined with the theory and research of natural science, the ancient rockets finally turned into the modern launch vehicles, which are indispensable to the development of aerospace exploration.
The word "rocket" appeared as early as in the third century during theThree Kingdoms period(220-280). In 228, the Wei State took the lead by applying a torch to each arrow in an attempt to guard Chencang (in today's Baoji City of North China's Shannxi Province) against the invading troops led by Zhuge Liang, the prime minister of the Shu State.
Hao Zhao, the Wei general, used fire arrows to burn down the cloud ladders (mobilesiege ladders) of the Shu troops, and was therefore able to defend Chencang. Thus the word rocket, meaning fire arrow, came into existence, referring to the inflammable materials attached to the end of an arrow, which was mainly used as a weapon to set a fire.
By the late 10th century in the Song Dynasty (960-1279), the Chinese had adapted gunpowder to rockets. To make such an arrow, first apapertube was made; then the gunpowder was put inside the tube, which was then attached to an arrow to be launched by a bow. Those were the first and most primitive rockets in the history of humankind.
Later, improvements were made on such arrows. For example, the gunpowder was directly carried inside an arrow, and the thunderous sound from the explosion of the gunpowder could frighten away the enemy.
