The world's first flying car.
According to the records of Suzhou Prefecture Chronicles, during the Qing Dynasty in China (the 17th century AD), there was a skilled craftsman Xu Zhengming in Suzhou, who spent nearly ten years to build a "flying car" with rotating flying wings. People sit on the chair of the "flying car", pedal with their feet, and through the mechanical transmission of the rotors, the "flying car" is actually more than a foot above the ground, and takes off to cross a small river.
After Xu Zhengming's "flying car" was built, it did not receive sponsorship and support from the outside world, and his wife also complained that his family was becoming increasingly poor and difficult, and there was no way to continue to improve the "flying car" he designed. After his death, his wife was so grief-stricken that she burned the "flying car" in a fit of rage. It's a pity that the world's first human-powered aircraft has disappeared like this.
According to the above simple historical records, it is estimated that the "flying car" created by Xu Zhengming is a rotor driven by the power of human feet. There are estimated three technical reasons for not being able to finalize it: 1
The materials used in ancient times were mainly iron and wood, and the fuselage must not be light. 2.There is a problem of rotation of the reaction force of the fuselage after leaving the ground, and it is estimated that it was not properly solved at that time.
3.The pneumatic efficiency itself is relatively low, and the strength of the human body is too small, so no one has been able to develop a successful human power.
It is said that the Ming Dynasty in China had a rotor toy such as "bamboo dragonfly", and it was not impossible for later generations to enlarge it for the development of manpower helicopters. According to the above account, "more than a foot above the ground, soared over a small river. It is estimated that when he stepped on the "flying car", he had a lot of power in a short period of time.
Most likely, on the condescending embankment, desperately taking off, in a semi-gliding state, crossed a small river more than ten meters wide.
Nowadays, science and technology have been much more advanced than in the Ming and Qing dynasties, and even ordinary people can buy aluminum alloy, stainless steel and plastic, epoxy resin and other light and strong materials, as well as many ready-made sports equipment and accessories that can be imitated and borrowed. Under such conditions that are much superior to the ancients, is it possible for the Chinese people to build a "flying car" driven by manpower, and repeatedly verify the ancient legend of Xu Zhengming, even if he can fly over a horizontal distance of more than ten meters.
Ben Ma has been obsessed with aviation since childhood, and has privately studied aviation principles for many years, and has designed countless one-man aircraft; We know very well that under the current ordinary conditions, the maximum strength of an ordinary person in a short period of time is at most only enough for a self-made "human-powered aircraft" to barely take off, and there is simply not enough strength to maintain and continue to fly; Therefore, this kind of "human-powered aircraft" is called "jumping insects". The so-called success of ordinary people is just gliding and jumping farther after takeoff.
Last year was the anniversary of mankind's "100 years of aviation," and Lao Wu of Nanjing City also successfully tested a self-made amphibious aircraft. Generally, it is more difficult for individuals to rely on private forces to build a standard ultralight aircraft, but it is still possible to build an ultralight special aircraft that can carry people into the air. Human-powered aircraft is one of the varieties of ultralight aircraft, and its sports nature is somewhat similar to that of bicycles

In myths and legends, Chang'e is a relatively early dream or tentative expectation of Chinese flying, and in ancient Chinese mythology, flying does not need to use any tools, and directly flies in the air. Sun Wukong's somersault of 108,000 miles is China's most beautiful idea of flying. Flying against the wind can also reflect the earliest discovery of the principle of flight in China, that is, the application of wind buoyancy.
About the flight in reality, there was a man named Wanhu in the Ming Dynasty, and he was the first to think of using the thrust of the rocket and the buoyancy of the kite to send himself into the air, but in the end the rocket **, he died.

There are many legends and stories about flying in ancient China, and here are some of the more famous ones:
Hou Yi shoots the sun: According to legend, there was a sharpshooter Hou Yi in ancient times, who was extremely capable and shot ten days away with a bow and arrow. Ten days after Hou Yi shot away, he was about to fly to the sky, but because his wife Chang'e mistakenly took his elixir and turned into the moon in the sky.
In order to find his wife, Hou Yi flew to the sky and spent the rest of his life in the Moon Palace.
Kwafu chasing the sun: Kwafu is the hunting god in ancient mythology, who wants to catch up with the sun in the sky. So, he started running and chased until he reached the horizon, but the sun never caught up.
Eventually, he died from chasing the sun excessively, but his image was described by later generations as a man or animal that could run very fast.
Battle of Chiyou: According to legend, there was a warrior Chiyou in ancient times, who was very powerful, wielding the ** Ge in his hand, making the entire sky extremely bright because of the brilliance of ** Ge. He led his people into a fierce battle with the Yellow Emperor's side, and was eventually defeated by the Yellow Emperor.
According to legend, after Chiyou's spirit left his body, he turned into a huge bird and soared into the sky.
Green Dragon and Xuanwu: There are four mythical beasts in legend, namely the Green Dragon, the White Tiger, the Vermilion Bird, and the Xuanwu. Among them, the green dragon represents spring and the east, and the xuanwu represents winter and the north.
According to legend, on some special festivals or occasions, people will imitate these two sacred beasts with items such as ribbons to express their admiration and prayers.
These stories and legendary images of flying are important artistic elements and symbols in ancient Chinese culture, and have also become one of the important parts of Chinese culture.

The scholars of the Ming Dynasty were ten thousand households.
At the end of the 14th century, Wan Hu, a scholar in the Ming Dynasty, tied 47 homemade rockets to a chair, sat on the chair himself, held two large kites in both hands, and then asked someone to light and launch. It was envisaged to fly using the thrust of the rocket, coupled with the power of the kite. Unfortunately, the rocket **, Wanhu also gave his life for this.
At the moment, only rockets can send people into space. Based on this standard, the earliest attempt to fly to the sky should be about 600 years ago. According to the research of Western scholars, Wan Hu was the first person in the world who wanted to use rockets to fly.
Wanhu took into account the rising power of the kite to fly forward, which few people could have imagined. In honor of Wan Hu, the International Astronomical Union named a crater on the moon after this ancient Chinese.
