Super Weapon Exchange System

Qin Guan's life in the country has entered a flat state again.

Although the situation in the date palm country is becoming increasingly tense, in China, this is only a few words in the news, just a topic people talk about after dinner. All of this is due to one thing, that is, the motherland Strong and stable!

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

When Qin Guan thought of this, his heart was surging. My motherland will be so powerful that it is impossible for people to touch it. And myself, I am the guardian of this powerful motherland and the promoter of high-tech technology!

"Mr Qin, what we are going to go today is the ordinary equipment developed by an ordinary lower-level enterprise. Don't bother you to go there yourself?" On Qin Guan's special train, the scholar asked Qin Guan.

It wasn't a big deal at first, but after Qin Guan heard about it, he couldn't wait to come. This made the talent suspicious. Qin, don't you have other intentions?

"Yes, now is the high-tech era, but some very common equipment can also be used in high-tech fields. Take this airship as an example. Although it has a history of hundreds of years, even It is now, and it is still valuable."

That's right, the project Qin Guan visited this time was the first flight of the airship. The scholar really couldn't understand this. What's so good about that kind of thing? It existed hundreds of years ago.

Before airplanes were invented, humans were able to fly into the sky. The earliest was to use hot air balloons, but hot air balloons could not control the direction and could only move with the wind by the wind in the sky. Later, there were fish-shaped airbags. , Relying on people to paddle to advance, and later, the paddle was changed to a propeller, the airship has the current basic structure.

Airships were once very popular, and they were a tool for people to travel. The huge Zeppelin brought the airship to a climax. Later, it even started intercontinental sailing. Unfortunately, the good times did not last long. The hydrogen charged inside was easy to burn. It happened several times. After the accident, it fell into a low ebb.

Now, the airship is a kind of equipment that has been marginalized, so the scholars do not understand this. Where did Qin's interest come from?

"Compared with airplanes, an airship does not require power to generate lift, so it stays in the sky for a long time. This is the greatest value of the airship." Qin Guan said to the Xiucai: "Don't look at this big guy who seems to be very backward. , But in some respects, it is a low-cost and most suitable equipment. Let me give you an example. Now our mobile communication is already very extensive. If a natural disaster occurs somewhere, mobile communication will be interrupted. At this time, we can send an airship over, equipped with a communication transponder on the airship, which can quickly restore mobile communications in the area, so that the disaster-stricken personnel can talk to their families to report safety, and it can also play a role in disaster relief on the spot. ."

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

The first large airships were all hard-shelled structures, but the big ones were inconvenient to put away. Therefore, modern airships are all soft. After releasing the gas, they can be directly received in the lower pod and used to Towed away, more flexibility.

"If necessary, we can even install 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 give you a holiday. You and Xiao Lu, go nearby. Turn around, you haven't lived in the two-person world for a long time."

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

Nothing else matters. What the Xiucai is most worried about is that Qin Guan can't help but curiosity. He wants to go up and take a look. Such a thing must never happen.

If it goes to heaven, it's still worth it! Scholars cannot afford this responsibility.

"Xiu Cai, we have been together for so long, do you think I am such a person?" Qin Guan asked, how about the trust between people, I will be self-willed, and then make you embarrassed?

Looking at Qin Guan's questioning gaze, the Xiucai nodded earnestly. That's right, President Qin, you really are such a person. You have to promise me that you don't get up when the time comes!

After the shaking train ran for a day, the next morning, they came to the place where the airship was flying. Qin saw the excited expressions of the technicians. Now, North Industries Corporation is a well-known company in the country. After graduation, many college students, They are all looking forward to working in such a company, and President Qin is even more famous. It is a great encouragement for them to see their airships.

"Mr Qin, this is the first helium-filled manned blimp that we designed and developed by ourselves. We call it CA-80. It adopts internationally existing new technologies, new equipment, new materials and new processes. . Moreover, it is completely our own design and knowledge, and we own all of our intellectual property rights." The designer of the airship said to Qin Guan.

Qin nodded his point of view: "Yes, you are all about originality now, and everyone can rest assured to do research. That is the best. Now, what are everyone waiting for?"

"Mr Qin, we are waiting for helium." The designer said: "We can only start the test flight until helium is transported to us."

Anything that wants to fly has to overcome gravity. The anti-gravity statement is nonsense. In the air, it can be overcome by lift. This is the principle of an airplane, and it can also be overcome by buoyancy. This is an airship. .

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

Hot air is one kind. In the past, hydrogen was the most commonly used. It was very light and easy to prepare. Even now, children’s toy balloons can fly into the sky as soon as they let go. What goes in is hydrogen.

Although hydrogen is very convenient, it has one disadvantage. It is easy to burn and it is the most efficient fuel. You can see the liquid hydrogen and liquid oxygen engine in the rocket. Therefore, many accidents in the past were caused by hydrogen. The airship in China no longer uses hydrogen gas, but another helium gas.
