Chapter 1098: At Worst, Unplug the Network Cable

Max was stunned.

He himself has thought of many ways, the most feasible of which is to dig a tunnel and open up the warehouse without anyone noticing, but the engine is too big after all, and the tunnel must be very big, and it is not convenient to use machinery. Equipment is not easy to steal.

Qin Tao's plan was simple and straightforward. Get Lao Maozi drunk, open the warehouse door, and take the things away in a big way!

Mr. Qin is indeed Mr. Qin, and the solutions he provides are so simple and feasible!

Max nodded excitedly: "Okay, let's do it! Mr. Qin, I don't think our plan can be announced to the outside world yet. We should make the project plan ourselves first. After we complete this interstellar transportation system, we can't announce it to the outside world." Chi, by that time, our stock will definitely be able to increase several times.”

Qin Tao nodded: "You must also consider the risks involved. Don't rush and take your time, especially this recycling."

Later starships often exploded on the launch pad, but Qin Tao knew that the research and development of this new technology was not that easy, and it still had to be stable.

After all, reusable rockets are still a new thing, and many technologies need to be studied. Among other things, if it is just a fuel tank, it will be scrapped after one filling and it will be refilled multiple times. The quality required is different.

Max nodded: "We know."

The matter was said and it was already eleven o'clock in the evening. Qin Tao yawned and planned to go back to sleep. However, after walking out, he saw several figures in the corridor and immediately smiled bitterly. It seemed that he could not go back today.

Just get a room in the hotel and go to bed when you're done.

"Mr. Qin, I heard that you have reached an agreement with Lao Maozi. You want to use several RD170 engines as collateral to borrow 100 million from them to build heavy rockets?" Xu Qiang asked Qin Tao.

"Yes."

"Mr. Qin, do we have a chance to get access to this kind of engine?" Wu Sheng asked excitedly.

"Do we need this kind of engine?" Qin Tao was curious.

It is said that the Long March 5 has just embarked on the fast track of research and development. The rocket project of the Long March 9 should not have been approved yet, so there is no need for such a large rocket engine.

For a long time, the main force in domestic launch rockets has been the Long March 2. This rocket was transplanted from the Dongfeng 5 technology back then and was used until the 1980s. China began to demonstrate new large-scale launch vehicles. After all, the old Long March rocket series existed. The carrying capacity is low, the core diameter is small, there are too many models, the model spectrum overlaps, the reliability is not high, the launch preparation period is long, and the propellants of dimethylhydrazine and dinitrogen tetroxide used are highly toxic and expensive, all of which are Needs to change.

In the 1990s, two RD-120 engines were used in China to conduct principle research and carry out key technology research. Based on these technologies, the YF-100 liquid oxygen kerosene supplementary combustion cycle engine project was established, which became the boost for the Long March 5. machine engine.

After entering the new millennium, the hydrogen-oxygen engine used in the core stage of the Long March 5 was also approved, forming a new Long March 5 series. The thrust of these engines is not large, and it is still far away from the RD170. There is a need for such a big guy. ?

"Of course." Wu Sheng nodded: "Mr. Qin, although this engine is a large engine with a thrust of 800 tons, it uses a four-combustion chamber solution. Viewed separately, one combustion chamber has a thrust of 200 tons. Even if we only get a quarter, it will be a big inspiration."

Fluid mechanics is a very complex subject. The complexity lies in the fact that many of the situations cannot be simulated by computers. It can only be verified through practice. If you double the proportion of a fifty-ton engine, you can get a 100-ton engine. tons of engines?

The answer is no, because after scaling up, the internal conditions have changed and the combustion conditions have also changed.

Therefore, every engine with different thrust needs to be re-verified. In many cases, it cannot be simulated, so it is necessary to conduct experiments again and again to find the most suitable layout.

Now, if we have this kind of engine as a sample, our own rocket engines can quickly transition to a new era: one combustion chamber of 200 tons, two combustion chambers of 400 tons, four combustion chambers of 800 tons, In this way, you can get whatever thrust you want, and no matter how much thrust you want to build a rocket in the future, you will be able to do so with ease.

Qin Tao suddenly thought of something: "Our current Raptor engine is two hundred tons. We build two combustion chambers, which is four hundred tons, and four combustion chambers, which are eight hundred tons. For our starship company, Doesn’t this engine make sense?”

This isn't right. If it was really meaningless, then Max wouldn't be so excited.

Xu Qiang shook his head: "Mr. Qin, what you are talking about is equivalent to multiple parallel engines, not strictly one engine. An engine with multiple combustion chambers can cut off part of it to reduce thrust. However, an engine with small thrust needs to It’s not easy to add combustion chambers to increase thrust.”

"Why?"

"Because an engine not only has a combustion chamber, but also a turbopump and a pre-combustion chamber." Wu Sheng continued to explain: "Take the RD-170 as an example. Although it has four combustion chambers, there is only one turbopump. , this turbo pump needs to provide fuel to the four combustion chambers together, so that the four combustion chambers can be started simultaneously, which is much simpler than the parallel structure of four engines. "

For rocket engines, the turbopump is also a very important component. It requires a high flow rate to inject a large amount of fuel into the combustion chamber for combustion. The performance of the turbopump of a high-thrust engine is higher and does not require any electronic control. , as long as the turbo pump is placed in the center and the lengths of the four fuel pipes are the same, the goal of synchronous start can be achieved, which is much easier than connecting multiple engines in parallel.

"Rocket engines that use staged combustion technology also need a pre-combustion chamber. To simplify the design, Lao Maozi uses two pre-combustion chambers, so that they can be easily split in half. As for splitting again, it is also possible. That’s just less fuel injected into the pre-combustion chamber.”

Qin Tao nodded. Sure enough, he was specialized in the art. As a warship builder, he knew too little about spacecraft and aerospace.

"Lao Maozi will send four RD170s and one RD180. At that time, we will probably tinker with one more and provide one to Starship Company and one to our relevant units."

Xu Qiang nodded, and Wu Sheng thought of something: "Mr. Qin, after we get the engine, we will definitely disassemble it and study it. Later, when Lao Maozi redeems these mortgaged engines, he finds that the engine has been disassembled. What to do after that?”

They obtained advanced engine research from Mr. Qin, which was a huge favor from Mr. Qin. They couldn't cause trouble for Mr. Qin! In contrast, Max doesn't have this idea. For him, it's just a split, and there's no interest on the money we borrowed.

Qin Tao smiled: "Do you think they can redeem it? With Damao's current technology, can US$100 million in funds be used to develop an advanced heavy rocket?"

Lao Maozi doesn't have this strength!

Even the United States doesn't dare to boast that it can be invented, let alone the old man. The 100 million is just for pre-research, and it will probably be spent completely. Next, it will definitely have to borrow and use more engines. Come get a mortgage!

Moreover, even if it is done, will it be useful? According to them, it is to provide launch missions for the Starship Company's lunar landing base. What if by that time, our own interstellar transportation system has been developed? Then use your own launcher. There is no need for Da Mao’s rockets, and Da Mao himself can’t use them. The huge investment can only be wasted, and these engines cannot be redeemed. They will probably have to be used by the Starship Company. .

Wu Sheng and Xu Qiang smiled knowingly and said no more.

Before they knew it, the time had passed twelve o'clock, and Qin Tao was yawning. The two of them were too embarrassed to disturb Qin Tao anymore, so they planned to say goodbye and leave. However, before leaving, Qin Tao couldn't help but ask. : "Does our national team have any new ideas? For example, for the Rockets, besides the Long March 5, are there any other models?"

Well, the big guys sat back and continued chatting.

"Of course not. We believe that if we want to carry out deep space exploration, we must have a heavier rocket! We plan a brand new heavy rocket. The diameter of the rocket body will reach 10 meters, the height will reach 110 meters, and the take-off weight will be about 4,000 tons, with a take-off thrust of 5873 tons. Once such a rocket is successfully developed, the carrying capacity of low-Earth orbit will reach more than 150 tons, and the carrying capacity of the Earth-to-Moon Transfer Orbit will reach more than 50 tons, even if it is to fly to Mars. , and can also have a payload of more than 37 tons.”

The main cost of human space launches is to overcome the gravity of the earth. Therefore, the payload sent to the moon will not be much larger than the load sent to Mars. Anyway, during the long voyage, most of the time is inertial flight. .

This brand-new rocket will be the main force in the future, and it is also the model they are looking forward to catching up with Starship Company. This brand-new rocket requires a more powerful engine. Surveying and mapping to imitate the RD170 is very important. Of course, it must also be improved.

This will be a rocket more powerful than the Saturn V, and all astronauts have full confidence in this rocket.

Qin Tao also discussed it and waited until two or three o'clock before falling asleep, thus delaying the next day. When he got up, it was already past ten in the morning.

"Mr. Qin, the contract details have been drafted over there. Damao has proposed an important plan, which is to install a camera inside the warehouse where the rocket engines are stored, and transmit it to them through the Internet for supervision anytime and anywhere." Max was very excited. in a hurry.

Da Mao attaches great importance to this kind of engine. Not only must it be guarded outside, but it must also be monitored inside to avoid various accidents!

"Then how did we respond?"

If you are not allowed to pretend, it will definitely mean that there is something wrong in your heart.

"We proposed that if they wanted to install it, they would have to pay for it themselves, not only the installation fee but also the annual network usage fee."

Sure enough, the people sent to negotiate were all very smart, and they could quickly find Damao's weakness: Damao was short of money, and since monitoring was needed, monitoring money had to be spent!

"Da Mao refused and discussed this topic for a long time, then put it aside and talked about other things."

"We can hold on and wait until all other terms have been negotiated. When we come back to this topic, we take a step back and ask one side to be responsible for half of the expenses."

Max was stunned: "Mr. Qin, if this is the case, then we can't stop this. If surveillance is installed, Da Mao can supervise it anytime and anywhere. How can we do anything?"

Max was very anxious.

Qin Tao smiled faintly: "Will it happen if I unplug the network cable?"

Short-distance video surveillance uses shielded signal lines, but if you want to extend the distance, you can only use the Internet. In later generations, network surveillance is becoming more and more common. Even if you install surveillance at home, you will use the Internet. .

Things like the Internet are unstable, and network failures may occur at any time.

Unplugging the network cable is a cunning operation of many conspirators, especially Wall Street, which has been used several times to trick everyone into committing suicide by jumping off the building.

When it's time to take action, just unplug the network cable. Anyway, the engine will definitely not be exposed to the outside. It is put in a box. After the finished engine is moved away, just put two more empty boxes. Changing a civet cat to a prince should not be a simple matter.

Max thought for a moment: "Will they let the people guarding the outside come in to check because of this kind of network failure?"

No matter how well disguised the wooden box is, it is still fake. As long as the wooden box is opened, the conspiracy will be exposed.

"Check? Just pay them tens of thousands of dollars in sealing fees. Besides, if you don't want to unplug the network cable, you can also manipulate the monitoring equipment and input false signals."

Unplugging the network cable is simple and straightforward, but it is easy to cause sequelae. Then change to a complicated operation, such as disconnecting the monitoring equipment and inserting the video that has been prepared long ago. This way, it will be silent and no one will notice.

This is not a difficult task, after all, Mingzhou Group has a powerful organization like Goose Factory.

"Well, let's use this plan." Max nodded and put down the top priority in his heart.

"By the way, Mr. Qin, we have collected lunar base construction plans from around the world and selected the most suitable one. Do you want to take a look?"

"OK."

So, Max turned on the computer he carried with him. When Qin Tao saw the moon base displayed on it, he immediately became happy: "Isn't this the Red Alert Base?"

The Red Alert game is a game developed by Goose Factory. Qin Tao said a few words when chatting with them, and they made a game based on Qin Tao's ideas. Unexpectedly, it was very popular.

Now, this optimal lunar base construction plan looks somewhat similar to the base in Red Alert.

Max nodded: "Yes, it looks similar on the outside, but it has a lot of scientific thinking inside."

Max wanted to continue the introduction, but Qin Tao had already waved his hand: "This plan is okay to fool people, but it will be too difficult to actually build it."

Too difficult? Max was a little curious: "Mr. Qin, isn't it normal for us to use mature 3D printing technology to make special bricks, and then use these bricks to build houses? It is always more convenient to use local materials than to transport them directly from the earth. "A lot?"

"Yes, 3D printing technology is very advanced, but it is also a waste to use it." Qin Tao said: "In order to resist meteorites, this house has to be built very thick, which means it is very heavy and the strength is difficult to guarantee. We Why go to all this trouble? Wouldn’t it be better to just dig a hole?”

There is no atmosphere on the surface of the moon, so even a tiny meteorite will hit the surface of the moon directly. This is quite dangerous. Under the influence of the moon's gravity, small meteorites will also turn into bullets. Occasionally, they will land on the moon and wait there. It's okay for a few days, but if you want to live for a long time, you have to live in a sturdy house.

The design plan in front of him is to build a house with lunar soil. Qin Tao came up with a better suggestion: let's live directly underground!

"Mr. Qin, if we want to dig a hole, wouldn't it be better for us to find a solid crater to dig the hole in?"

It is easy to dig a hole underground, but after digging the hole, it is not easy to put the equipment in. After all, the cave is just a bunker, and a special cabin must be placed inside the cave.

Dig in the crater and be level with the moon, so that you can even directly insert the cabin of the starship into it as a residence.

"Well, yes, it's up to you to think about the specific design. Of course, you can contact our infrastructure company."

To engage in construction, we still need the infrastructure company of Mingzhou Group. The title of infrastructure madman is not for nothing. In this case, will those people still have the opportunity to build a house on the moon? Thinking of this, Qin Tao also became full of expectations.

Max left and Xu Zhengyang walked in.

"Mr. Qin, Your Excellency Nicholas called and decided to visit us soon."

"What is he here for?" Qin Tao was very curious: "Just for this matter of the aerospace department?"

He thought it was because of the issue of monitoring fees. These old aerospace guys couldn't negotiate properly and called Nikolai here. Isn't this too much of a fuss? As for that?

"No, it's about the amphibious assault ship. The first one has almost been built and is about to be launched. He wants to come to us to participate in the launching ceremony."

"So fast?"

How fast is this! Xu Zhengyang also felt a little helpless. Mr. Qin was messing around in other businesses every day and had almost forgotten his old one.

In March of this year, Lao Maozi came over to see the progress. The shell of this warship was almost completed. Now a few months have passed, and of course it has to be launched. This is due to lack of manpower, which has delayed some time, otherwise It's been long gone.

To Lao Maozi, this is a brand new giant ship. They value it very much and of course they will come over.

"Okay, then I'll take him back. The launch of this amphibious assault ship is indeed a big event. It's time for Nicholas to come over." Qin Tao said: "When the outfit is completed, it should be delivered to Lao Maozi next year at the latest. past."

During the construction, many projects were carried out, so outfitting was much easier. Moreover, the outfitting work of the amphibious assault ship was simple. Unlike the destroyers and frigates, which had a large number of weapons and equipment, it was only necessary to install the living facilities, which was faster.

When the first amphibious assault ship was delivered, the Russians should have brought the aircraft carrier over for repair, right?

PS: Thank you for your support, fellow book lovers!

I recommend a new book by a good friend: "Spy Shadow Reverse War". An old writer who has been in the online literary world woke up and returned to Shanghai on the eve of the Battle of Shanghai. He tore the Japanese invaders apart, killed the traitors, and fought against the wind to create a brand new world!

This book is also known as "Against the Wind" and "I am the Ace". Changfeng returns to the spy war, a blood-burning work.
