Chapter 1639

Just look at the parallel space-time. The space shuttle is retired, but the spacecraft is still in service. Advanced ideas do not necessarily mean advanced equipment, but also in line with the actual situation.

Everyone was discussing. Outside, Xiao Guo slowly came in. He gently pushed the door open and sat in the last row.

Xiao Guo was very excited. He didn't expect that he had come out here to have a look at the air show, but it was an aerospace event. Where did he expect to meet his old classmates here, and now he just caught up with a meeting!

When he thought of his old classmates, he thought of the check in his pocket and felt a burst of tension. What's that? You leaked it yourself? Pay yourself?

He knew that divulging secrets was quite serious, even sentenced, an act of endangering the country, but the check was constantly hitting his heart.

Money!

That's money. In recent years, earth shaking changes have taken place in the country. Although Xiao Guo's salary is also rising, how can he not envy those who do business when they make a lot of money? He also wants money. Money is not everything, but he can't do without money.

He tried to suppress his idea. Now, when attending the meeting, he was informed late and came late. I don't know what they are talking about?

"Mr. Qin, your analysis is very reasonable. It seems that we don't have to look at the height of the mountain. We'd better aim at the spacecraft. In fact, even if the spacecraft, we're just demonstrating in advance, and the country hasn't started yet," Ren said.

Qin Guan nodded: "yes, our manned space industry must step by step, not fast, but stable, and firmly go out. At the same time, there is another purpose to call everyone here for a meeting."

What's the purpose?

The people looked at Qin Guan and waited for him to go on. Qin Guan didn't sell off and said his ideas. "We should demonstrate a new launch site."

In launching satellites, Eagle country is more convenient than bear country. Why? Because bear country is in high latitude and Eagle country is in low latitude, it is easier to use the earth's rotation.

The earth is a big ball. It rotates continuously and once every 24 hours. It is easy to imagine that the north and south poles do not rotate. The more you go to the equator, the greater the linear speed of rotation.

All spacecraft on the earth are launched to the East, because the earth rotates from west to East and launches to the East. In this way, we can effectively use the linear speed brought by the earth's rotation. The more we go to low latitudes, the more we can use.

Sitting on the ground and traveling 80000 miles a day means that when you are on the ground, you are also moving with the rotation of the earth.

For example, on the equator, the linear speed is up to 1670 kilometers per hour, five times that of the fastest EMU!

At 60 degrees north latitude, the speed will be reduced to 837 kilometers per hour.

After the founding of the people's Republic of China, the Han country developed the missile industry and aerospace at the same time. It established a space city and developed three launch sites. However, they are all in the north of the Han country. In this way, it is impossible to make effective use of the favorable aspects of the earth's rotation.

At that time, it was also helpless. After all, at the time of site selection, the monkey country was still at war. If there was a situation, coconut island might become a battlefield. It would be unsafe to arrange the satellite launch base here.

But now it's different. International relations have begun to ease, especially the steady growth of the military strength of the Han country. Anyone who dares to make trouble here can be taught to be a man by Flying Leopard fighter bombers and c802 series missiles. The new four King Kong of the navy are also majestic, not to mention that China is building its own aegis warships.

The navy has been able to protect the safety of Coconut Island!

The experts present were smart, and immediately someone said, "if it's the most efficient, let's directly build a launch site in Coconut Island. In this way, our launch vehicles of the same model can increase the carrying capacity by 10%."

Apart from others, this data is true. If the current launch site can launch the Long March 2 rocket with a carrying capacity of 10 tons, the carrying capacity in Coconut Island can reach 11 tons! In the aerospace field, it is valuable to add even one kilogram of weight, let alone 10 percent!

Coconut Island, located in the southernmost part of the motherland, is an island separated by a strait from the mainland of the motherland. If it is connected, it is the peninsula. The whole island is like a pear in shape. It belongs to a subtropical climate and a tourist resort. The light time of the whole year is very long and there are quite a lot of launch windows.

In the past, there was such an idea, but they finally gave up because of various difficulties. Now, Qin Guan finally proposed to build a launch site here!

"In the future, our newly developed long March 5 series launch vehicles will be launched in Coconut Island, which can save our fuel more, and our manned space program can also start here," Qin Guan said.

Qin Guan only chose the most appropriate one. Coconut Island is really good. The natural conditions are very good. Especially in winter, it is cold and freezing. It is dangerous to launch rockets. Why did the space shuttle Challenger explode? Isn't an O-ring frozen?

If you come here, you don't have to worry about this problem. It is a tourist attraction all the year round, with a good climate and a considerable number of launch windows.

"But what about transportation?" someone asked.

So far, the production and assembly of rockets are all in the rocket factory in the capital. In the past, they were transported to the destination by railway, and then tested, erected, fueled and launched.

I went to coconut island. There is no road to get through. How can I transport it?

Qin Guan smiled: "transportation is better. We can transport directly by ship!"

The engineer who asked the question immediately patted himself on the head. Yes, I didn't think of it!

The establishment of the fourth launch site in Coconut Island is also related to the Long March 5. This new generation of high thrust rockets adopts a larger diameter design. In this way, the previous railway transportation mode is not easy to use. The bridges and caves along the way are not wide enough!

However, there is no such concern about using ships for transportation. If it is produced from the rocket production plant in the capital, it can be directly transported to the port of Haihe River. From there, it can be shipped to coconut island in one breath. In terms of transportation, it is absolutely convenient.

Xiao Guo listened quietly. It seems that this is a long-distance planning meeting of space system. The establishment of this launch site will take at least five years.
