A big country of aerospace with black technology

The blue sea and blue sky, although there is no soft white sand beach, but there are also jagged black rocks.

In late autumn, on the island at the southern tip of the motherland, you can still feel the aftertaste of midsummer.

Even the wind that blows from the sea from time to time does not have the bleak feeling of the inland.

"I feel that the temperature in the Dragon Tower is higher than that in the Xichang Base."

"I don't know if it's my illusion?"

Although it was already November, Geng Bo, who was wearing long-sleeved trousers, still felt very hot.

While fanning himself with the hem of his jacket, he couldn't help but compare the temperature in Longlou Town with that in Xichang.

Although Zhang Xingyang was also wearing a long-sleeved blue and white aerospace uniform, he was not as afraid of heat as Geng Bo.

Even the buttons on the collar are tightly fastened.

"The latitude where the Dragon Tower is located is lower than that of Xichang, and it is already a tropical area."

"It's normal to be a little hot."

Apart from Zhang Xingyang and Geng Bo, there were quite a few people present.

Including Sun Hongtao, the leader of the aerospace department, Li Ruian, the leader of the land management department, local leaders, and their entourage.

Zhang Xingyang's identity here this time is quite different from before.

In the past many times, although Zhang Xingyang was actually in charge of many matters of the low-orbit satellite communication network, after all, there was a big boss named Chen Zhongyan in charge.

Ever since Chen Zhongyan recommended Zhang Xingyang to the country to become the actual person in charge of the low-orbit satellite communication network during his lifetime.

Considering that Zhang Xingyang's age might not be enough to convince the public, Sun Hongtao became the leader on the surface.

But everyone knows that it is impossible for Mr. Sun to manage many details of the low-orbit satellite communication network project, and these tasks are basically assigned to Zhang Xingyang.

But this time, so many people came to the big island at the southern tip of the country in order to select a new launch site for the low-orbit satellite communication network project.

The forty satellites in the first phase of the project are small in number after all, and only two rockets are needed to complete the launch.

So it is not very necessary to build a new launch site.

But the goal of the second phase of the project is to build and complete the domestic satellite communication network.

More than four thousand satellites need to be launched!

As for the more distant third-phase project, more than 50,000 satellites will be deployed in space to cover the whole world!

Even the Hongyan rocket with a very powerful carrying capacity can launch more than 30 satellites into space at a time.

The second phase of the project also requires more than 130 launch missions to complete.

If you continue to launch satellites at inland launch sites, you will need to consume more fuel and transportation costs.

Possibly as many as billions!

This is also the reason why their group ran all the way to Dragon Tower, a small place that no one in China knew before.

This place is relatively close to the equator, located at 19 degrees north latitude, which can make better use of the inertial centrifugal force brought by the earth's rotation speed and save rocket fuel.

"Xiao Zhang, how do you think this place compares with the Sanya we saw before?"

At this time, Sun Hongtao came over and asked Zhang Xingyang what he thought of Dragon House.

In fact, Zhang Xingyang and his team had already visited two other places before they came to Dragon Tower for investigation, namely Sanya, which was also on the island, and Yangjiang, which was opposite the island.

Compared with the two places on the island, Yangjiang has a higher latitude, so it is the first site to be excluded.

There are only two places left in Sanya and Wenchang Dragon Tower that are still on everyone's shortlist.

"I still prefer to choose Wenchang as the location of our new generation launch site."

Zhang Xingyang first gave his own opinion.

"oh?"

"Tell me why."

Sun Hongtao was also a little curious at this time, what kind of advantages Wenchang would have in the eyes of professionals like Zhang Xingyang.

"The first is the transportation issue. Qinglan Port is next to Wenchang, which is convenient for us to carry out rocket transportation."

"You also know that although the Hongyan rocket has made great progress in thrust compared with our previous rockets, the size of the corresponding rocket is also a lot larger."

The first thing Zhang Xingyang mentioned was the transportation of heavy rockets.

"In ordinary railway transportation, ordinary freight cars cannot be transported at all."

Because the carriages of ordinary trains will not exceed 3.5 meters, and the diameter of Hongyan rocket is about 4.5 meters.

"Usually more roads are used for transportation, and railway transportation also requires special carriages, and the cost is too high."

"And if we use sea transportation, both in terms of transportation safety and economy, it is much better than road transportation and rail transportation."

Because the satellite communication network project can be regarded as a commercial project from a certain point of view, the cost issue during the entire project process is a key consideration for everyone.

Even if the cost of each rocket transportation can be reduced by one million, then the second phase of the entire low-orbit satellite communication network project can also save more than 100 million in costs.

Sun Hongtao also agrees with this point. After all, the whole project is too huge, and it is good to be able to save some.

"According to what you said, isn't Sanya better than here?" Sun Hongtao raised his own question.

Although Sun Hongtao is not from the aerospace system, he also knows some basic knowledge. Basically, the closer the rocket is to the equator when launching, the better.

Sanya is further south than Wenchang in terms of latitude.

If it is out of cost considerations, choosing Sanya seems to be a better choice from the perspective of saving fuel.

"Sanya is better if you look at it purely from the latitude."

Zhang Xingyang also knew what Sun Hongtao was thinking about, and began to analyze the issue of Sanya as a launch site in detail.

"However, the current level of commercial development in Sanya is too high. If the rocket launch site is chosen there, there may be many inconveniences."

On the eve of the 21st century, an island at the southern end has also ushered in the era of large-scale development, and Sanya has also developed in this wave of development.

The priority development is the tourism industry. Every day, many northerners come to Sanya to experience the joy of the blue sea and blue sky.

Therefore, if the rocket launch site is selected here, once any accident occurs, it will cause great human and economic losses.

"However, this is also a small part of the reason, mainly due to the location of the east and south of Sanya."

Zhang Xingyang then talked about the terrain distribution of Sanya.

"Sanya is a roundabout, with many mountains and islands in the east and south."

"And our current rocket launch trajectory is basically towards the east or southeast."

"In comparison, the east and south of Wenchang are vast seas, and the first-stage rocket can fall directly into the sea after separation, ensuring maximum safety."

The rocket wreckage fell into the sea, bringing more protection to the safety of people's lives and property, and there will be no situation where the rocket wreckage falls into residential areas, causing casualties or property damage.

However, after the completion of Wenchang, coastal residents in Southeast Asia can often pick up gifts from heaven from the beach, and the shell says Longguo Aerospace's high-strength aluminum alloy!

Sun Hongtao really hadn't thought of this level before.

But Zhang Xingyang hadn't finished speaking at this time, and then said:

"Similarly, the meteorological conditions here in Wenchang are slightly better, both in terms of wind speed and humidity."

Speaking of this, Zhang Xingyang felt his mouth was a little dry, swallowed, and continued:

"The last important reason is that the land price in Wenchang is cheaper!"

At this time, the real estate speculation fever on the entire island has just passed. Although the real estate bubble has burst, Sanya, as an important tourist destination, is still not cheap.

Even if the entire launch site construction project is land expropriated by the state, it will still cost a lot of money.

At this time, Wenchang was just a place with nothing to ask for, and the cost of land acquisition was very low.

"So on the whole, it is a better choice to choose Wenchang as our new generation launch base."

After talking a lot, Zhang Xingyang finally concluded.

After listening, Sun Hongtao still didn't express his point of view, but looked at the rolling waves not far away, and was silent for a while.

"Old Sun, it is said that the new generation launch base will belong to the Xichang Launch Center?" Zhang Xingyang also felt a little gossip at this time.

This gossip has just appeared in the aerospace system not long ago, and everyone is not sure whether it is true or not.

After all, at this time, the location of the new-generation launch base has not yet been determined, and the issue of ownership is even more unknown.

"Of course, this launch base is inextricably linked to the Xichang launch base in all aspects, and it is more convenient for Xichang to manage it."

Sun Hongtao did not act as a riddler, but gave the answer directly.

Zhang Xingyang also remembered many rumors before the establishment of Xichang at this time.

In the 1970s, the country actually considered establishing a space launch site on the island, but the international environment was relatively complicated at that time. Considering the pressure on national defense, the launch site was finally established in Xichang, which is safer.

"Wouldn't the Xichang launch base be responsible for all the construction expenses?" Zhang Xingyang asked another fatal question at this time.

Although there is no direct affiliation between the Rocket Research Institute and the Xichang Launch Base, almost every rocket launch has been carried out at the Xichang Launch Site before, and there is a deep brotherhood between the two.

So considering this possibility, Zhang Xingyang couldn't help but sweat for the Xichang launch base.

After all, the construction of the launch site requires at least tens of billions of construction funds. Even if the Xichang launch base itself is squeezed out, it will not be able to spend so much money.

"That's not true. The state will provide part, the local government will provide part, and finally the Xichang launch base will provide part."

Sun Hongtao did not give the worst answer in Zhang Xingyang's opinion.

But even so, Zhang Xingyang estimates that the Xichang launch base will not be very low.

However, these are not things that Zhang Xingyang needs to undertake, so he didn't care too much after asking.

I turned my head and shifted my sight to the sea surface. Although it was November, the sea breeze blowing in bursts still gave people a refreshing feeling.

Feeling the coolness on his body, Zhang Xingyang couldn't help thinking in his heart:

"Will the wind in the South China Sea blow into space with our rocket?"
