Chapter 1639: Fourth rocket launch site

Just look at the parallel time and space. The space shuttle is retired, but the spacecraft is still in service. Advanced concepts do not necessarily mean advanced equipment. It must be in line with the actual situation.
Everyone was discussing, outside, Xiao Guo slowly walked in, he opened the door gently, and sat down in the last row.
Xiao Guo was very excited. He didn't expect that he would come here to take a look at the air show, but it was an aerospace event. Where did he think that he met old classmates here, and now he just happened to be in time for a meeting!
When he thought of his old classmates, he thought of the check in his pocket again, and he felt nervous for a while, what was that? Did you leak the secret? Pay yourself?
He knows that leaking secrets is quite serious, and will even be sentenced. It is an act that endangers the country. However, the check is constantly hitting his heart.
Money!
That's money. Over the past few years, earth-shaking changes have taken place across the country. Although Xiao Guo's wages are also rising, how can he not envy him when he sees those who do business make a lot of money? He also wants money. Money is not everything, but no money is absolutely impossible.
He suppressed this idea forcefully, and now, attending the meeting, he was notified late, late, don’t know what they were talking about?
"Mr. Qin, your analysis is very reasonable. It seems that we don’t need to look at the high mountain from this mountain, but aim at the spacecraft. In fact, even for the spacecraft, we are just pre-arguing. The country has not started yet." Ren Lao said.
Qin's point of view: "Yes, our manned spaceflight business must take steps one step at a time, not seeking fast, but steady, and going out firmly. At the same time, there is another purpose for calling everyone here for a meeting."
There is a purpose?
Everyone looked at Qin Guan and waited for Qin Guan to continue speaking, but Qin Guan didn't sell Guanzi and spoke out his own thoughts. "We should demonstrate a new launch site."
In launching satellites, Eagle Country is more convenient than Bear Country. Why? Because the bear country is at a high latitude and the eagle country is at a low latitude, it is easier to use the earth's rotation.
The earth is a big ball, which rotates continuously, making a round every 24 hours. It is easy to imagine that the north and south poles actually do not rotate. The more you go to the equator, the greater the linear velocity of rotation.
All spacecraft on the earth are launched eastward, because the earth rotates from west to east and launches eastward, so that the linear velocity brought by the rotation of the earth can be effectively used. The lower the latitude, the more it can be used. .
Sitting on the ground and traveling for eighty thousand miles a day, that's what it means. You are on the ground and moving with the rotation of the earth.
For example, on the equator, the linear speed is as high as 1,670 kilometers per hour, which is five times that of the fastest EMU!
At 60 degrees north latitude, this speed drops to 837 kilometers per hour.
After the founding of the People’s Republic of China, Han State developed the missile industry and at the same time developed aerospace. It established the Space City and developed three launch sites, but they were all located in the northern part of Han State. In this way, the earth’s rotation could not be effectively used. Upside down.
It was also helpless at the time. After all, when the site was selected, the Monkey Kingdom was still fighting. If there were circumstances, Yedao 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 Han’s military strength has grown steadily. Whoever dares to come here to make trouble, the Flying Leopard fighter-bombers and C802 series missiles can teach them how to behave. The four new naval forces King Kong is also majestic, not to mention that the country is building its own Aegis warship.
The navy has been able to protect the safety of Coconut Island!
The experts on the scene were all clever, and someone immediately said:
If it is the most efficient, let’s just build a launch site on Yedao. In this way, our launch vehicles of the same model can increase the capacity by 10%. ability!"
Among other things, this data is real. If the Long March 2 rocket is launched at the current launch site, the carrying capacity can reach ten tons, then in Yedao, the carrying capacity can reach eleven tons! In the aerospace field, even one kilogram more weight is precious, let alone 10%!
Coconut Island, located in the southernmost part of the motherland, is an island, separated from the motherland’s mainland by a strait. If connected, it is a peninsula. The entire island is shaped like a pear. It has a subtropical climate and belongs to tourism. In the resort, the sunshine time is very long throughout the year and there are quite a lot of launch windows.
In the past, I had this idea, but because of various difficulties, I finally gave up. Now, Qin Guan finally proposed it, and build a launch site here!
"In the future, our newly developed Long March 5 series carrier rocket will be used as a launch base on Yedao Island, which can save our fuel. Our manned spaceflight program can also start here." Qin Guan said.
Qin Guan only chose the most suitable one. Yedao Island is indeed good. The natural conditions are very good. Especially in winter, the sky is freezing and it is dangerous to launch rockets. Why did the Challenger space shuttle explode? Isn't an O-shaped sealing ring frosted?
If you come here, there is absolutely no need to worry about this kind of problem. It is a tourist attraction all year round, the climate is good, and there are many launch windows.
"But, what about transportation?" someone asked.
So far, rocket production and final assembly have been carried out in the rocket factory in the capital. In the past, it was transported to the destination by rail, and then tested, erected, refueled and launched.
I went to Coconut Island, but there is no road to pass, how to transport it?
Qin Guan smiled: "Transportation is better. We can transport it directly by ship!"
The engineer who asked the question immediately patted his head. Yeah, I didn't expect it!
The establishment of the fourth launch site in Yedao is also related to the Long March 5. This new generation of high-thrust rocket adopts a larger diameter design. In this way, the previous railway transportation method is not easy to use. The bridge holes along the way It's not wide enough!
However, if it is transported by ship, there is no such concern. The rocket production factory in the capital can be directly transported to the port of Haihe, and from there, it will be shipped to Coconut Island in one breath. In terms of transportation, this It is definitely convenient.
Xiao Guo listened quietly. It seemed that this was a long-distance planning meeting for the space system. The establishment of this launch site would take at least five years.
