Super Weapon Swap System

Qin Guan's life in China has entered a dull one.

Although the situation in yezao country is becoming increasingly tense, at most, it is only a few words in the news and a topic of discussion after dinner. All this is because of one thing, that is, the strength and stability of the motherland!

War is the most terrible. Countries entering war will inevitably be accompanied by turmoil and pain. The people in war are the most miserable. If there is no war, we must make the motherland strong!

When Qin Guan thought of this, he was filled with emotion. My motherland is so powerful that it is impossible to touch it. I am the guardian of this powerful motherland and the promoter of high-tech technology!

"President Qin, what we are going to go today is the ordinary equipment developed by an ordinary subordinate enterprise. Don't bother you to go there in person?" the scholar asked Qin Guan on the special train of Qin Guan.

It wasn't a big deal, but after Qin Guan heard about it, he couldn't wait to come, which made the scholar doubt. Mr. Qin, are you trying to do something else?

"Yes, it's a high-tech era, but some very common equipment can also be used in the high-tech field. Take this airship, although it has a history of hundreds of years, it is still valuable even now."

Yes, the project Qin Guan visited this time was the first flight of an airship. The scholar really couldn't understand it. What's good about that kind of thing? Hundreds of years ago.

Before the invention of the aircraft, human beings could also fly into the sky. At first, hot-air balloons were used. However, hot-air balloons could not control the direction. They could only float with the wind by relying on the wind in the sky. Later, there were fish shaped airbags, which moved forward by rowing. Later, the rowing was changed into a propeller, and the airship has the current basic structure.

Airships were once very popular as a tool for people to travel. The huge Zeppelin airship brought the airship to a climax. Later, it even started intercontinental navigation. Unfortunately, the good times did not last long. The hydrogen filled inside was easy to burn. After several accidents, it fell into a low tide.

Now, airship is a kind of marginalized equipment, so scholars don't understand it. Where did Mr. Qin's interest come from?

"Compared with an aircraft, an airship does not need power to generate lift, so it stays in the sky for a long time, which is the greatest value of an airship." Qin Guan said to the scholar: "Although this big guy seems very backward, in some aspects, it is the most suitable low-cost equipment. Let me give you an example. Now our mobile communication is very extensive. If a natural disaster occurs in a certain place, the mobile communication will be interrupted. At this time, we can send an airship with a communication transponder on it The mobile communication in this area will be restored soon, so that the affected people can call their families to report safety, and also play a role in the disaster relief on the scene. "

Low cost equipment has the unique advantages of low-cost equipment. Airships are still useful in modern society. In addition to allowing people to ride in scenic spots, other aspects, such as traffic command, television broadcasting, air patrol, remote sensing detection, etc., can also be extended to military, such as anti submarine reconnaissance, air command, etc.

The original large airships were of hard shell structure, but it was inconvenient for everyone to put them away. Therefore, modern airships are soft. After releasing the gas, they can be directly received in the pod below and towed away with a trailer, which is more flexible.

"If necessary, we can even mount the millstone and use it as an early warning airship." Qin Guan said, "you, don't underestimate the airship. If you don't want to see it, you can have a holiday. You and Xiao Lu go around. You haven't seen the world of two for a long time."

The scholar quickly shook his head: "Mr. Qin, you still don't understand what I mean. When we arrive at the scene, you have to promise me that you can't get on the airship."

It doesn't matter what else. The scholar's biggest worry is that Qin Guan can't help his curiosity. If he wants to go up and have a look, such a thing can't happen.

If you go to heaven, that's great! The scholar can't bear this responsibility.

"Scholar, do you think I am such a person when we have been together for so long?" Qin Guan asked. What about the trust between people? Will I be self willed and embarrass you?

Looking at Qin Guan's questioning eyes, the scholar nodded seriously. Yes, President Qin, you are really such a person. You have to promise me not to go up at once when you take off!

After the shaking train had been running for a day, the next morning, they came to the airship test flight site. Qin Guan saw the excited expression of the technicians. Now, North Industrial Company is a famous company in China. Many college students are looking forward to working in such a company after graduation. President Qin is even more famous. Such a boss can come Looking at their airship, it was a great encouragement to them.

"President Qin, this is the first helium filled manned soft airship designed and developed by us. We call it ca-80. It adopts the existing new technologies, new equipment, new materials and new processes in the world. Moreover, it is completely designed and known by ourselves and owns all our intellectual property rights." the designer of the airship said to Qin Guan.

Qin Guan nodded: "yes, now we all pay attention to originality. It's the best for everyone to settle down and do research. Now, what are you waiting for?"

"Mr. Qin, we are waiting for helium." the designer said, "we can't start the test flight until helium is transported to us."

If anything wants to fly, it has to overcome gravity. The argument of anti gravity is nonsense. In the air, it can be overcome by lift. This is the principle of aircraft, and it can also be overcome by buoyancy. This is airship.

Buoyancy is determined by the ancient Archimedes principle. The size of buoyancy is equal to the gravity of the surrounding air. Therefore, if you want buoyancy to overcome gravity, you must fill the lighter gas in the airship.

Hot air is a kind of hot air. In the past, hydrogen was the most commonly used. This thing is very light and it is not difficult to take it. Even now, children's toy balloons can fly into the sky as soon as they let go. They are filled with hydrogen.

Although hydrogen is very convenient, it has a disadvantage that it is easy to burn and is the most efficient fuel. Just look at the liquid hydrogen and liquid oxygen engine in the rocket. Therefore, many previous accidents were caused by hydrogen. Modern airships no longer use hydrogen, but another kind of helium.
