Chapter 733 Help

Among all the solutions, the module cluster form is the simplest, and its technical route is very close to that of Tiangong and the International Space Station. It means that different functional components are connected and installed together, and subsequent maintenance is also very convenient.

However, the shortcomings are also obvious. The strength of this assembly method is too low for a space port of more than 10,000 tons, and the orbit change capability is extremely poor. At the same time, the size of each module limits the upper limit of the space port, but for a small experimental port It's acceptable.

The second one goes a step further and mainly increases the potential of the space port, but it requires on-orbit processing and assembly capabilities and a large amount of manpower.

The third type of overall rotating gravity type is quite advanced. It has the same configuration as the giant spaceport that will be launched in the future. It is huge in size and has strong expansion potential. It can also provide different gravity environments, but it also brings a straight line between cost and construction difficulty. The rise also poses considerable challenges to designers.

The current rotating gravity space station Advance has an empty load of only 1,500 tons. Expanding it 10 times or even 20 times will require a new structural design, otherwise the centrifugal force of rotation will tear the spaceport itself apart.

When an object with a weight of tens of thousands of tons and a span of more than 200 meters begins to rotate, every second is a huge test for the load-bearing structure, and most of the design team's energy must be focused on this.

In terms of project volume, the first two options were the most reliable, but there were many supporters of the radical route. In the end, all three options were put on the stage, and then a comprehensive decision was made.

…

Perhaps because they knew that the representatives from various companies who rushed to join the meeting were unprepared, at this time, staff entered the auditorium to distribute technical manuals. Long Jiacheng, sitting in the front row, was almost the first to get it.

After picking it up, I found that this technical manual, which is not too thin, does not have any unnecessary decoration. It is either data or patterns. It describes the basic structure and some details of the three argumentation schemes in detail.

The introduction of the plan is very detailed, and even people who are not in the aerospace industry can basically understand it.

After the introduction of the plan, there are several pages of densely packed professional fields, which are the parts that need to be solved by the participating companies' industries.

It’s not that these existing aerospace companies haven’t done it before, but the space port is too big, and quantitative changes lead to qualitative changes, and it also puts forward new requirements for quantity and quality.

For example, the simplest ventilation system and air conditioning system are not impossible for Xinyuan and the space agency. However, for a project as big as the spaceport, there are too many projects involved and not enough energy. It is more appropriate to hand it over to specialized companies.

In the past, whether it was various spacecrafts or space stations, they were all facilities with hundreds of tons or thousands of tons. The production demand was very small, so aerospace companies just made it.

However, this is not the case for the spaceport project. Each subsystem may require a specialized supplier, and the maintenance costs after completion are enough to support a large number of parts companies.

Long Jiacheng's eyes quickly scanned the lines of text, then he took out the signature pen he had prepared long ago and began to check.

This is an unprecedented opportunity. Even if he chooses a field that he is not good at at all, once he conquers it, it will bring unimaginable benefits. He needs to choose all possible fields to get involved in.

Private aerospace companies like him who had more contact with Xinyuan responded the fastest, but others were not weak at all. The people who were still whispering quickly quieted down and concentrated on reading the brochures in their hands, and then roughly selected their own companies to undertake subsystem scope.

The silence lasted for about a few minutes, and suddenly someone in the front row raised his hand.

Zhong Cheng immediately nodded and asked someone to hand over the microphone. Others quickly focused their attention on the standing person and noticed the "TISCO" logo on the person's chest.

He was still wearing work clothes, he was about forty or fifty years old, and he should be a chief engineer level figure.

"Hello Director Zhong, I noticed that there is no mention of steel demand. For example, if the empty weight of a spaceport is 40,000 tons, at least 10,000 tons will be the skeleton structure. How can we meet so much steel demand?"

Zhong Cheng: "Of course there is a demand for this. We temporarily plan to supply it through the future lunar steel complex, which is more convenient and easier. The cost of supplying it to the earth is too high."

Someone immediately chuckled after hearing this explanation. Even though the spaceport is huge, steel companies can only develop a few new materials, and they cannot compare with other suppliers in terms of share or technical capabilities.

However, the chief engineer did not show any disappointed expression. He nodded and sat down. Then Zhong Cheng's voice sounded:

"The invitation to Taigang this time is also because of the Lunar Steel Smelting Consortium. United Mining has selected Taigang as a partner to jointly build the steel consortium at the Yushu base. I hope you can actively cooperate."

At this time, the chief engineer of Taiyuan Iron and Steel Co., Ltd. showed a smiling expression at the right time, causing the mentality of others to immediately change to jealousy.

Lunar joint steel company!

I thought I couldn't catch up, but I didn't expect that they had already joined the game.

With TISCO taking the lead, someone else quickly stood up, but they still asked questions:

“I noticed that the spaceport plan is only part of the ‘Southern Gate’. Does this mean there will be more and larger space building plans in the future?”

Zhong Cheng: “The naming of the first spaceport is still being solicited, but what I can reveal is that the first spaceport is experimental in nature, and the second is formal in nature, and its mass may be more than 150,000 tons.

In addition, there will be many construction plans for celestial bodies and extraterrestrial planets on a scale similar to the space port in the future. The cycle of the "Southern Gate" project will be more than 20 years. "

These words reassured everyone. They clearly stated that this business could last for 20 years, and investment in research and development would definitely not be a loss.

"Then our Juli Group hopes to undertake the traction cable part of the rotating gravity part, as well as the external fixed ropes."

"Okay, now the staff has registered, please contact us after the meeting."

Zhong Cheng replied immediately, while also casting encouraging glances at the others.

"Sunshine Energy can undertake the design of standby generator sets and all-electric basic power systems! We have designed supply ships and have similar experience!"

"We have experience in water circulation systems and can combine them with air circulation systems!"

“We can do the instrumentation and lighting.”

"What are the requirements for fire extinguishing equipment? Can you find out later."

"We can also make fire extinguishing equipment!"

"..."

Long Jiacheng looked at the enthusiastic crowd and finally took advantage of the opportunity to raise his hand.

The Tianbing Aerospace representative on the side came over to see the sub-projects he had circled, and Long Jiacheng simply said it directly:

"Lingxi hopes to take over the internal communication control system of the entire spaceport and unify the interface standards of each part."

"Uniform standards?"

Long Jiacheng smiled slightly: "We have Xinyuan's RX02 bus protocol authorization, so we can cooperate."

The other party's pupils immediately shrank. The communication system was definitely a huge project. He hurriedly rushed over and started looking through whether there were any similar projects. He was ready to raise his hand at any time.

…

Class B base.

He Ruang stood on the runway of the base, raising his hands to cover the sun with other people from the Aviation Development Committee, and looking hard at the clouds in the sky.

There were many people gathered around them, most of them employees of the base, and others were basically personnel from the space agency and the military, all of whom were uniformly observing the sky from time to time.

There are drones constantly flying around the airport to prevent any outsiders from approaching, but in fact nothing can be hidden.

Seven days ago, the Enterprise took off from the Northwest Second Experimental Base and entered space. It orbited the earth several times and then docked with the Tiangong Space Station.

In September, the Tiangong Space Station suspended tourism reception for 15 days due to the lunar blasting operation, which was just in time to keep the Enterprise a secret.

In the past seven days, astronauts at the Tiangong Space Station, Serev and others conducted multiple extravehicular operations to ensure that the angular appearance of the Enterprise was not deformed or damaged due to severe friction in the atmosphere. They also checked that the electromechanical and power systems were free of malfunctions. Landing operation approved.

Unlike when taking off, the Enterprise needs to use its aerodynamic shape to decelerate and brake to save fuel when landing. It will circle around the landing center. When approaching landing, it will easily pass through densely populated areas at low altitude, losing the confidentiality conditions during takeoff.

So far, only Aramco in the world has discovered the anomaly of the Enterprise, because the Aerospace Development Commission has not even disclosed this experimental operation to the outside world, and it is only now that it has been forced to decrypt the Enterprise.

As described in the NPAE's original technical information, the "Everest" engine belongs to the last generation of rocket jet engines. Like the A100, it is the pinnacle of the traditional technical route, squeezing out the final value of existing aerospace propulsion theories.

The technological shock that its emergence has brought to other organizations is absolutely beyond imagination, but now is no longer the time to care so much, and strengthening ourselves is the urgent task.

"Is the Enterprise entering the atmosphere now? Is it entering from Central Asia, or from the northwest?"

He Ruang asked the engineer from the Fourth Institute next to him, but the other engineer also shook his head:

"It's hard to say, it depends on their choice."

Unlike any previous aircraft and spacecraft, the Enterprise is very flexible when it returns to the atmosphere. If you want to save fuel and reduce risks, you can slowly glide and use aerodynamic deceleration. The span is very large, not much different from an aerospace plane.

However, if it is impossible to fly over a long span due to special reasons, it can also circle around a vertical line and descend quickly, but adjusting the attitude requires more fuel and the risk is greater.

These two are only extreme situations. AI can flexibly adjust according to actual conditions and does not require special route planning on the ground.

…

Over Kazakhstan.

Meng Senlin finally understood the feeling described by the Lunar Team. When they rode the Jiuzhang, due to its special configuration, the thrust did not always come from a certain direction. The unfixed direction and posture of the thrust could cause the situation to change with just a few clicks. People are dizzy and it takes a long time to adapt.

In fact, the Enterprise's situation is more serious than theirs. Because of the additional aerodynamic deceleration program, although the Enterprise's general movement route is a smooth transition line, it will actually adjust its attitude every few seconds, or it will suddenly change its attitude in a certain airspace. Start slowing down in a big circle.

Except for the flight computer, no one knows what attitude the Enterprise will adopt in the next second. The acceleration is sometimes upward and sometimes downward, but more often it is irregular and may appear in any direction.

Even though this acceleration is not large, it is more uncomfortable than high overload in one direction.

Serev, who had been feeding chicken soup to the flight crew seven days ago, said nothing now. The landing process was much more uncomfortable than taking off. Even his body in his prime could not bear it. He just closed his eyes and took a deep breath to fight against the dizzy feeling in his mind. .

Meng Senlin still maintained his condition. He was now a member of the Space Force, so of course he had to do his best to adapt to his weapons.

"..."

The Enterprise once again began to perform circling aerodynamic deceleration, but because its main movement was still gliding at high speed, from the ground it looked like an out-of-control leaf spinning and falling in the wind, completely out of control——

"товарищ, товарищ! Этодальневосточноепространство!"

A rapid grunting sound suddenly came from the Enterprise's radio. No one on the flight crew could understand Russian, but Serev suddenly opened his eyes and looked out the window.

"It's the Far East Defense Force. They are asking us if we need help. They think our spacecraft is out of control."

Meng Senlin glanced at the radar. There was no change on it. The Enterprise was still at an altitude of tens of thousands of meters. The radar was mainly used to detect mountains and weather, and could not see small things such as airplanes.

But even if it gets out of control, I'm afraid the air defense force won't be able to help.

"Thank you, Chief Engineer, then please tell them that we are in good condition and thank them for their kindness."

"No problem, pick up the channel for me...Дорогойдаварик..."

…

"They said there was no glitch()!"

In front of the Enterprise, the MiG-31 pilot and his wingman who were conducting relay observations were also communicating about the strange aircraft in the sky.

The Enterprise was discovered by Lucia's vast monitoring network from the moment it entered the atmosphere, and was immediately reported. The Kremlin issued instructions to pay attention to this strange and unknown aircraft.

Along the border, fleets of aircraft continued to take off for accompanying flights, but the Enterprise's flight altitude in the previous section was too high and nothing was discovered.

Only now did Andrei see the huge radiation source and its rather unstable signal characteristics on the radar.

"What the hell is this? It's spinning, it's spinning! Is it a UFO!"

The first thing that the wingman pilot thought of was a flying saucer. After all, only a flying saucer could spin and fall like this. If it were a human spacecraft in this posture, it would definitely be destined to crash.

"Follow closely, it is about to enter China's airspace!"

Andre looked up and saw a flashing and extremely unstable luminous object. It really looked like a UFO.

The Enterprise's speed is much faster than that of the interceptor. It still maintains 5 times the speed of sound and will soon surpass them and enter its own airspace.

The two planes immediately turned around and began to return, but the four pilots were still discussing about the Enterprise.

"I bet it's not a winged craft, maybe a reusable rocket or something like that."

"The rocket broke so early! It must be round. It is a Chinese flying saucer!"

"There are actually astronauts in there, and they can communicate with us. Maybe it's an aerospace plane!"

"..."
