Crazy but romantic scientific fantasy.

In 1987, the special TV series "Dinosaur Katsse" filmed by Japan's Yuangu Company was first broadcast in China. The film's ratings were not high in Japan, but it was the first special film to introduce my country. In the environment of domestic science fiction -themed works that was still scarce, it won quite high popularity.

Many post -80s and even parts of the 90s have remembered the super weapon "artillery" in the film. After being launched by the special device of "Xiaguang 1", the actor can become a superman "Kesse" and fight with various aliens and mutant monsters.

"Human" is actually a "human" in Japanese, and "human artillery" should be translated into "human cannon". However, the sense of mystery and middle two brought by the literal translation is much greater than the translation. Since then, the "earth cannon" has also become a conventional name, which specifically referred to those cannons that can launch humans as artillery shells.

Looking at the artillery as a transportation tool, such an idea seems crazy, but it is one of the thousands of crazy ideas that humans have tried, and it is also the long -lasting subject of science fiction works.

The earliest concept of "earth cannon" was put into practical application is the acrobat actor of the circus.

On April 2, 1877, at the Royal Aquarium in London, UK, a 17 -year -old girl with a stage name "Zazel" performed the first "human artillery" performance with historical records. A British newspaper at that time roughly recorded the performance process:

"This young lady climbed into a large mortar very calmly ... Seeing a living artillery shell flew over the air and fell into the safety net safely, we were startled. Before I was scattered, she had already walked along the security net and bowed and smiled on the stage. "

She started her performance career at the age of 5

Although many people present must smell the smell of smoke, "Zezeel" was not shot out by the gunpowder bomb. In the performance, the actual amount of the gunpowder is quite small. The smoke manufactured is only used to enhance the sense of view and deceive the audience.

The cannon firing "Zesel" has a built -in ejection platform controlled by a rubber spring. The designer of this cannon is the inventor William Leonard Hunt, Canadian inventor. Based on the great success of the flying car of the stone car at the time, in 1871, he applied for the patent of the rebounder in the United States in the United States Later, I thought of installing the projector into a real cannon.

Even if the difficult performance of "do not imitate" in the circus, the danger of "shooting flying people" is one of the best.

Two years after the first performance, "Zezeel" encountered a performance accident. She should have been able to catch her security net to decay due to wear and let her fall to the ground. Heaven's performance. After the accident, the performance of this performance was too cruel and contrary to humanity, and some people had always hoped to ban various circus performance projects including "guns and shooting people".

Despite these hundred years, "Artillery Flying Man" performance has been improved a lot. Each circus has regarded the operating mechanism of the cannon with the internal structure as commercial secrets. The diameter of the cannon used is different from the length of the cannon. However, it can be confirmed that they use compressed air to shoot "human artillery shells".

Compressed air will push the platform inside the gun to the cannon mouth, and the "human artillery shells" on the platform will fly to the air under the influence of inertia.

It is not difficult to launch a person to the air. The difficulty is how to land safely, safe nets, water surfaces, or airbags, all of which are optional. Actors engaged in "human artillery shells" are far more cautious than we imagine. They will repeatedly calculate the cannon trajectory before launch, and they will also use a fake person who weighs a little bit more. Take your own life.

But any improvement and caution cannot avoid performing accidents. So far, more than 30 actors have been killed in such a performance, and the active "human artillery shells" are not more than double digits. The nearest tragedy and occurred in 2011. A 23 -year -old British stunt actor fell from an air over 30 feet (about 9.14 meters). Because the safety net failed, his head was on his body.

Obviously, whether the idea of "earth cannon" can be realized is how to make humans who have been fired out can withstand the toss like shells.

The "human artillery shells" performance of the circus tend to die, but their methods and methods are worthy of reference. In 2006, the U.S. Defense Senior Research Program (DARPA) borrowed the performance of the circus and applied for a patent of "human artillery". This device includes a diagonal rail with an 80 -degree angle on the ground, as well as ejection seats on the orbit. When the cannon was launched, the compressed air was released quickly, the seat ejected along the guide rail, and the special forces, police or firefighters on the seat were sent to the roof.

Patent demonstration

Darpa claims that they have a computer that can automatically design the correct rising speed and angle to ensure the minimum impact when landing. In theory, a 4 -meter -high launcher can ejected a person to the top of the 5 -story building in less than 2 seconds. Coincidentally, the real -time strategic game "Red Alert 3" launched two years later, designed a "bullfrog chariot" for the Soviet camp. In addition to having an air defense gun, bullfrog also equipped with a "military deployment system". At first glance, it is very tall. In fact, it is also a "human cannon" of a teacher inheritance.

Bullfrog tank

In terms of setting, this system also uses compressed air. In order to ensure the gas tightness, after the soldiers drilled into the car, the only way to leave was to be launched by the cannon. The cannon does not need to calculate the accurate ballistic, just to launch the adult to the "thousand -meter high", and the soldiers who are launched will use simple parachute to the front line, or some unexpected places.

Whether it is a circus, DARPA or a "bullfrog tank", the "human artillery" is designed for those who have suffered certain training. During the launch, "human artillery shells" need to withstand the pressure of gravity in a short period of time. Ordinary people who lack muscle strength may lose their consciousness under heavy pressure, unable to control their own attitude, and have no chance to open the parachute to open the parachute Essence

These concepts are only near the vision of vision. If the destination of the "human artillery shell" is set farther, for example, the moon must use a strong source of power to compress the air.

As early as 1865, "Father of Science Fiction", "Father of Science Fiction", "From the Earth to the Moon" by Rules Verner, fictional constructed a "human cannon" that can make human beings realize the moon landing. In the novel, a cannon club in the United States cast a half -mile (about 800 meters) "Colombia cannon", intending to use gunpowder power to send the hollow shells of three adventurers to the moon.

"From Earth to the Moon" has considerable insights. It is enough to send the cannonball out of the gunpowder of the earth, which will also press humans into minced meat. Therefore, "hollow cannon" is an indispensable part of manned space: hiding in an indestructible metal skin sac, the human body of human beings can withstand the acceleration that a shell should have.

But the "Columbia cannon" prophecy is not fully realized. In two world wars, the longest -caliber cannon has not exceeded 40 meters in length. After the war, the idea of "hollow cannon shells" evolved into a manned spacecraft and a rocket equipped with a spacecraft. The rocket used jet -type to promote the engine, which can provide a more stable and lasting acceleration. The only means.

"Human cannon" lacks a certain amount of generalization and practicality, which is of course a conclusion obtained by scientific practice. However, there is indeed some kind of charm, which makes it difficult for science fiction authors to give up such a "delusion". At the expense of citing all the possibilities of the future, it proves the value of the "earth cannon".

Abandoning the thick and long metal cannons, instead uses emerging materials and electromagnetic technology to create large electromagnetic guns or quality drives. This idea is very attractive. At present, the technology trees in China and the United States have taken the lead in pointing out the electromagnetic ejaculation, which can already ejection aircraft on the aircraft carrier.

The plane is not driving. Even the ace driver is risk of crash. Therefore, the science fiction author tends to design some "skin" that is stronger than the aircraft and relatively easy to control some, such as mechanical exoskeleton, large mech, and even energy shields. The force drops to as low as possible.

It is not impossible to replace the carrier -based aircraft with Gundam

Like Liu Cixin's short -story science fiction novel "Earth Artillery" written by Verne, Liu Cixin also designed a "big cannon" that can send humans into space, but it has some different ways.

The essence of this cannon is a tunnel that runs through the heart. It is made of a magnetic field in the cannon through a current in a "new solid -state material" collection. Human beings need to wear a sealed cover with superconducting coils, and the current in the coil has a magnetic field with the opposite direction, which will generate thrust. Because the length of the "Earth cannon" is equivalent to the diameter of the earth, the "human artillery shells" launched from it can enter space with the help of a "gentle acceleration", which can be described as solved the problem from the source.

Novel festival

From Verne to Liu Cixin, countless science fiction works have different interpretations of the theme of "artillery on the world", which reflect the charm of "science fiction" itself to some extent. Some scientific fantasies are more biased towards the scientific side, similar to the predictions of the future, and it is likely to become a reality with the help of science; other more pretty fantasies may never be realized, but they have unique romantic colors. It provides a space -like reverie space.
