Rockets are modern vehicles for launching satellites and spaceships, which were first invented by our ancestors. At first, it was only used to set off fireworks during the Spring Festival holiday. In the13rd century, people used rockets as weapons of war, which were later introduced to Europe.
The first person who thought of flying with rockets was the clever China people-ten thousand yuan households in the Ming Dynasty. /kloc-At the end of 0/4th century, 47 homemade rockets were tied to chairs by Ming literati, and they sat in chairs with big kites in their hands. Imagine flying into the sky with the thrust of a rocket and landing smoothly with a kite. Unfortunately, the rocket exploded and thousands of families gave their lives for it.
At present, only rockets can send people into space. According to this standard, the earliest manned space flight should be about 600 years ago. Western scholars have verified that Wan Hu is "the first person in the world who wants to fly by rocket".
The idea of Wanyuanhu is ridiculous now, but it was creative at that time, and his basic methods and brave spirit were affirmed and admired by people. He considered not only the ascending tools, but also the parachute kite that landed safely, which was unprecedented. To commemorate thousands of families, a crater on the moon was named after this ancient China man.
Some people say that China's "manned spacecraft research" actually started more than 600 years ago. After Gagarin, the first astronaut, went to heaven 4 1 year later, this great process finally returned to China, the "motherland" where human beings went to heaven. "Shenzhou" is to fulfill the ancient dream that thousands of families in Qian Qian have not realized.
According to Civilization magazine, Herbert S Zim, an American rocket scientist, mentioned in his book Rockets and Jets published in 1945 that "at the end of 14, there was a China official named Wan Hu who was behind a seat. He tied himself in front of the chair and held a big kite in each hand. Then let the servant ignite 47 big rockets at the same time, in order to fly forward by the power of rockets and the rising power of kites. "
Jin didn't mention the origin of "Thousands of Households Fly" in his book. Liu Xianzhou, a professor in Tsinghua University, first translated it into Chinese, and later the story of "thousands of families flying" was widely quoted in various forms. This matter has also been mentioned in some works of rocket experts in the former Soviet Union, Germany, Britain and other countries. At an International Astronomical Union in 1970s, a crater on the moon was named "Ten Thousand Households" to commemorate "the first man who tried to fly with a rocket".
There are some stories about thousands of families flying in the sky in Qian Qian that most people don't know.
It is said that Wan Hu used to be a carpenter and liked to learn crafts. After joining the army, he improved many vehicles and ships with knives and guns, and made many meritorious deeds in the war with Valla. He was favored by the general in charge of the squad and let him work in the weapons bureau. These two people are very close. Bambe is honest and straightforward, and never follows others' advice. Therefore, he offended a number of ministers such as Li, the right corps commander, and was removed from all his posts and imprisoned in the ghost valley in the upper reaches of Juma River.
Judy, the fourth son of Zhu Yuanzhang, the founding emperor of the Ming Dynasty, wanted to inherit his throne. On the one hand, he snared partisans and expanded the army; On the other hand, I collected all kinds of skills and dedicated them to Zhu Yuanzhang to please him. Li likes the prince, knowing that thousands of people use Bambei as a bird and want to use him as a dragon for the emperor. On the surface, thousands of families agreed to build the flying dragon, hoping to take this opportunity to rescue Bambei and fulfill their long-cherished wish of building birds.
Ten thousand households went to Ghost Valley to see Bambei, but it was too late. It turned out that Ben was harmed by the Walla army, and it was Li's secret message to the Walla army newspaper. Fortunately, seeing that the situation was not good in the class, the follower rushed out with his "rocket book". Every family is determined to build birds and realize Bambei's last wish. He carefully read the Rocket Book written by Bambe, made all kinds of rockets, and then drew the patterns of birds, which the craftsmen made according to the drawings. During the test flight, the bird was put on the mountain, and thousands of families picked up kites and sat on the bird's back. First light the bird's tail lead, the rocket ignites, and the bird flies forward from the mountain. Then two feet fired and the birds rushed into the air. Soon, the fire disappeared, and the birds rolled and landed at the foot of the mountain ... (Editor Ruan Zhifeng)
14 The harvest in autumn is to turn to autonomous driving.
Qian Xuesen told the young people the "story of ten thousand families" that his mentor Wang Shizhuo once told him.
This story happened in China in the15th century.
It was the nineteenth year of Xianzong Chenghua in the Ming Dynasty. There was a rich man's son named Wanhu. He is familiar with poetry books, but he doesn't take exams. Because he doesn't love official positions and loves science. He is most interested in gunpowder and rockets invented by ancient people in China. I want to use these two things with great thrust to send people into the blue sky and observe the high-altitude scene with my own eyes. To this end, he made full preparations.
On this day, he took two big kites and sat on a snake-shaped flying car with 47 rockets tied to it. Then he ordered his servant to light the first row of rockets.
I saw a servant with a torch in his hand. He came to thousands of families and said sadly, "Master, I'm so scared."
Wan Hu asked, "What are you afraid of?"
The servant said, "If we can't fly, our master's life will be in danger."
Ten thousand households laughed and said, "Flying has been my long-cherished wish for thousands of years in China. Today, even if I am shattered and blood splashes all over the sky, I will open up a road to explore the sky for future generations. Don't be afraid to wait, come and light the fire! "
The servants had to obey Wan Hu's orders and raise the burning torches.
Just listen to "boom!" There was a loud noise, and the smoke around the flying car was rolling and the flames were soaring. In an instant, the flying car has left the ground and slowly rose into the air.
Just as the crowd on the ground cheered, the second row of rockets ignited themselves. Suddenly, there was a huge explosion. I saw Wan Hu's flying car in the blue sky turned into a fire, and Wan Hu fell from the burning flying car, holding two huge kites on fire and landing on Wanjia Mountain.
Qian Xuesen paused here. A young man asked, "What happened later?"
"What happened later?" Qian Xuesen said regretfully: "Ten thousand families are buried in Wanjiashan where flowers are in full bloom. Of course, his flying career stopped. After the Ming Dynasty, especially in modern times, China's scientific and technological undertakings became increasingly backward and even bullied by foreign powers. However, Wan Hu's flying career has been recognized by the world. James mcdonnell, an American rocket expert, and Wan Hu, a young rocket expert from China, were the first pioneers of manned rocket flight. The snake-shaped flying car he developed is also an amazing invention in human history. "
"In fact, as early as the Ming Dynasty, China invented the secondary rocket. The multi-stage rocket is the first in China, a major breakthrough in human rocket technology and a precedent for modern multi-stage rockets. "
