1782: Joseph and Monte Goffel conducted the first hot air balloon flight test in France, using paper as an airbag, yes, you weren't dazzled. The world's first official hot air balloon was made of oversized cardboard boxes. Same with Kong Ming lanterns!

The balloon flew at an altitude of 33 meters, lasted 10 minutes, had a distance of 3.5 kilometers, and the passengers were a sheep and a duck. The fuel at that time was old leather boots and animal meat, so people at first thought that it was the foul smell that made the balloons fly.

Just one year later, in 1783, Rozier made the first manned flight in a hot air balloon in France.

1944: The Japanese released 9,000 balloon bombs into the United States, of which 3,285 landed along the coasts of the United States, Canada, and Mexico, and flew as far as Alaska. And as early as the First World War, balloon bombs appeared.

That's right, calculate the wind direction in advance, use the air current, and directly use the air flow to fly the bomb into the air with a balloon and fly into the enemy's city to explode.

It's for balloon bombs!

took Xiao He's information and saw the contents of the bomb, Zhu Zilong was really startled.

I thought, can this hot air balloon still be used like this?

Zhu Zilong, who was very interested, took a serious look at the information in this area and the method of making the bomb.

In the summer of 1944, Japan was defeated and retreated one after another, and in order to reverse the situation, Kokuaki X, who succeeded the British plane from the east to become the prime minister of Japan, adopted the suggestion of meteorologist Arakawa Xtoshi, and used the westerly wind belt of the Pacific Ocean to modify the balloon and load it with bombs and release it, in order to achieve the purpose of bombing the continental United States.

At that time, missiles that could automatically attack across thousands of miles had not yet been invented, and the Japanese stupid people could think of this. carried out the bombing of cottages, and sure enough, I have to say that I do have some real skills!

The balloon explosives and placement are easy to learn, as long as the balloon basket is filled with 30 sandbags weighing 2-7 kg. When the balloon flies below 9000 meters, due to the action of air pressure, the bolts that hold the sandbag will be automatically released, and the sandbags will be thrown down in turn, and the balloon will be raised due to weight loss.

When the balloon rises above 10,500 meters, one of the valves of the airbag will automatically open according to the physical inertia, and then smash rapidly to the ground.

Then, boom, explosion.

If you are afraid that the explosives will fly overhead, you can use a sandbag to connect an hourglass or a simple timer, calculate the approximate flight time, and fall semi-automatically. Except for the fact that the time of the bombing is a little slower and the accuracy is not high, the other operations are simply not too easy, not too easy!

According to a report in the San Francisco Evening News of November 4, 1944, the bombing of balloons that had traveled thousands of miles by stupid people in those days simply killed the Americans.

The inhabitants of the west seem to be facing the end of the world, and they are in constant fear. Lookout posts have been set up in various places to guard against the heavens. Some people sit on the sidewalk, always do not forget to look up to the sky, and mistakenly take a bird or an airplane for a "milky devil", causing a panic.

Sometimes I'm eating at home, or sleeping, commuting to work, or whatever, and all of a sudden, I find that there is an explosion nearby. Worry about life every day!

In the worst case, it almost blew up the White House and hit a power plant, causing blackouts in several cities in the United States.

If it falls in the arsenal, the Americans simply dare not imagine it.

Because this kind of balloon is small, it moves and floats erratically, there is no fixed time, and I don't know how many will come and when. Radar cannot detect it in advance, and it is impossible for planes to be on standby for 24 hours a day for inexplicable things.

Therefore, if the stupid people had done more and fought for the cost, the American people would definitely collapse early.

In 1945, there were rumors in the Americans that the Japanese were testing the use of bacteriological weapons in northeastern China. Therefore, the American people are worried that Japan will hoist bacteriological bombs and chemical bombs on balloons. The days go by, and I can't stop worrying every day!

But until the end of April, the "milky devil" was no longer visible, and this rare air battle ended inexplicably. The reason was that the Japanese army ran out of funds, and this plan was stopped. The Americans, with great rejoicing, waited for Japan to surrender!

After the end of World War II, the Far Eastern Military Tribunal included him in the list of war criminals in view of his crimes in World War II.

When the judge said that the destructive nature of the balloon bombs was far superior to that of the fierce combat troops, Arakawa was surprised at first, then regained his composure and said, "We have released a total of 9,000 balloon bombs in more than 4-6 months, and we regret that we were not able to carry it out!" ”

Seeing the information here, Zhu Zilong touched his chin and laughed.

Hehe, the stupid people don't have the funds, but I'm different. My opponent in the Ming Dynasty was just the Qing army, as well as various forces that lagged behind me for hundreds of years in terms of science and technology!

And he was super rich in the Ming Dynasty, and he will become richer and richer in the future, this kind of balloon bomb can be regarded as a long-term development of the military branch and workshop, and it will be very special!

Copycat long-range balloon missiles, it's a little exciting to think about.

From December to February or March of the following year, there is a strong sea breeze that often blows from the direction of Shandong to the territory of Houjin.

And now it is not far from December, and when I return to the Ming Dynasty, I will work overtime to get a batch of cottage balloon explosives.

For more than four or five months, hundreds of balloon bombs (copycat ICBMs) were released into the air, and then they could celebrate with wine at home.

Hahaha!

Even the wild boar skins of the post-Jin and Qing dynasties who did not have a navy, not to mention the air force, no country had an air force during the Ming Dynasty, and I don't know what an air force is.

Not to mention any countermeasures against air supremacy, it is easy for the Zhu family army to occupy air supremacy.

If the Qing soldiers shoot balloon bombs with arrows in the future, it will be better, and they will fall faster. If you don't shoot, you will still fall, play with them!

Thinking of this, Zhu Zilong's saliva almost flowed out.

The next day, he pulled Xiao He, who had recovered from his fracture, and asked him to take him to Nanjing's largest hot air balloon center.

Under the introduction of Xiao He, a regular customer, Zhu Zilong bought more than a dozen large hot air balloons. There are dozens of medium-sized balloons, and hundreds of small balloons (the kind that can be turned into bombs).

This kind of small hot air balloon, as long as it is made of similar materials, can be imitated even in the Ming Dynasty.

Of course, if you use 100% of the materials of the Ming Dynasty, you may not fly so fast, nor so stable, and not as high as the height of modern products.

Therefore, after Zhu Zilong was reminded by Xiao He, he privately purchased a large number of modern fabrics.

In order to strengthen the nylon cloth, it is waterproof, and it also has a certain anti-puncture function and is light in weight. Of course, the price is not cheap!

However, now money is not a matter for Zhu Zilong at all.

This time when he came back to modern times, he took a turn, even if Zheng He's cottage treasure ship No. 3 was thrown in Dongsheng Shenzhou and not transported, there are more than one billion in the bank alone. In addition, there are some antiques that have long been stored in the bank, as long as they are sold, the pressure of money will be solved in seconds.

This is a small hot air balloon that does not need to be heated.

Fill with lighter-than-air gases such as hydrogen or helium.

Perhaps the only thing that makes Zhu Zilong have a headache is how to solve the helium problem.

Helium is a non-renewable resource, there is no cheap synthesis channel, and once it enters the atmosphere, it cannot come back. At present, almost all of the helium that exists on Earth comes from it, and the amount of helium in radioactive gas deposits can be as high as 7%.

75% of the world's helium comes from countries such as the United States, which makes people feel more painful!

Only a few parts of China have them, and the gas giants such as Jupiter, Saturn, Uranus, and Neptune contain large amounts of helium. But obviously, for modern 21st century humans who haven't even gone up to Mars, this problem is thrown to the Ming Dynasty, it's just nonsense!

The content in the air is very low, and the cost of liquefaction extraction is too high. The Ming Dynasty did not have this technology to speak of!

It seems that Zhu Zilong has to focus on hydrogen for the gas problem of balloon bombs, even if hydrogen is easy to self-detonate, it must be used! -
