Chapter 286 We never believe in evil! [Request full order]
It can be said that 052D is the beginning of the rise of the Long Brother Navy.
After the great success of the 052D sea trial, in addition to arranging the accelerated production of the 052D destroyer, Wang Haoran also shared the design plan of the 055 destroyer.
The 055 destroyer has a displacement of more than 1.2 tons, and can even reach more than tons.
With a larger tonnage, there are more vertical launch systems, the anti-submarine equipment can be more advanced, and higher-power active phased array radars can also be arranged.
As the tonnage increases, the strength will naturally increase significantly.
Such a huge ship can really destroy an entire country with just one ship.
This is the country’s most important weapon.
Building such a giant ship is actually a preparation for future ocean cruising.
The navy's strength has increased significantly, so of course you can't just stay at home, you need to go out and explore.
There are many risks out there, but if you go out so often, won’t you become familiar with them?
In addition, if giant ships cruise around the world, we can basically guarantee our own shipping lines.
Any thief who dares to attack our maritime trade will be made to pay a heavy price.
Wang Haoran still remembers the Galaxy from his previous life!
Fortunately, in this life, it is only the mid-80s now, and we have already risen ahead of time.
If we rise at this time, there will be too many benefits.
Now, even French Chicken and Hans are not on the same page with Squid Thief.
The world divides rights and interests based on strength and technology.
Thinking of the Galaxy in his previous life, Wang Haoran remembered an imminent matter.
That is: satellite navigation system!
Today, Squid is tinkering with their GPS, and Big Bear is not willing to lag behind and is also researching and building its own satellite navigation system.
However, they haven't made much progress yet.
Squid has launched many experimental satellites in succession, but they still cannot achieve free satellite navigation.
This is mainly because there are still many limitations in current technology.
The first technological limitation is that high-power solar panels have not yet been developed.
The second is that there is no source of more accurate atomic clocks.
The third problem is that the integrated circuits of their functional modules are also relatively backward.
The fourth problem is that the satellite’s own protection problem in the harsh space has not been well solved, so that the satellite’s survival time in the geosynchronous orbit is quite short.
Of course, there are many other minor issues that also need to be resolved.
If these technical problems are not solved, the satellite navigation system will not be possible.
The GPS system has been in development since the early 70s, and even now, more than ten years have passed, but it is still not complete. It was not until the mid-90s that this thing was truly completed.
GPS is so important.
Once it succeeds, people all over the world will need to use it.
The GDP output value generated by this satellite navigation system is over one trillion yuan every year.
I'm not just joking.
Moreover, Squid used this system to create various problems and put forward various unreasonable demands.
This is also why even Europe began to prepare to develop its own satellite navigation system in the late 90s.
However, it is an indisputable fact that before the emergence of Long Ge's Beidou, it was Squid's GPS that dominated the global satellite navigation system.
Wang Haoran thought to himself, I must seize this satellite navigation system as soon as possible. We must be the first to build such a system that can not only serve military purposes, but also serve the people of the country and even the world.
At the same time, you can make money.
why not?
Thinking this, Wang Haoran went to discuss the matter with the designer again.
After listening to Wang Haoran's report, the leader nodded and said, "This satellite navigation system is indeed very important."
"In fact, Professor Qian and several other scientists have mentioned this before."
"The Academy of Sciences even held a meeting to discuss this."
"But after several discussions, we feel that this satellite navigation system has many extremely difficult problems, and it will cost a huge amount of money. If we want to completely complete this system, it will probably take at least 20 years and more than 100 billion yuan of investment."
"Therefore, the consensus is: let's see how Squid develops next."
"If Jusa can come up with something and succeed, we can learn from their experience, shorten the time and reduce the investment."
It turns out that there has been discussion about the construction of this satellite navigation system before.
The idea was shelved because the investment was too huge and the difficulty was too high. Even after more than ten years of work, there had been no progress. Everyone believed that continuing to invest rashly would be a waste of precious national resources.
The main reason is that the whole country is now vigorously carrying out infrastructure construction, and the cost of infrastructure construction is extremely high.
Although Longguo has developed well, it is still a little tight now.
This is also the main reason why the satellite navigation system has been shelved.
Wang Haoran smiled and said, "Leader, I think that at this point in time, we can no longer continue to cross the river by feeling the eagle sauce."
“We have to take our own initiative!”
"If we can be the first to master the satellite navigation system, then we can dominate the global satellite navigation system and earn a lot of commercial profits from the world."
"At the same time, this will also be of great help in enhancing our global influence."
"Please think twice."
The leader smiled thoughtfully and said, "Haoran, it's not that I don't support it, but you have to come up with a specific plan for me, right?"
"Let me see the details of your plan."
"Only in this way can I have confidence in you!"
Wang Haoran smiled and said, "I can understand your thoughts."
"I can write a satellite navigation development plan. If the country can give me 5 billion yuan in funding every year in the next five years, I can build a good satellite navigation system covering the whole world within five years."
The leader was a little moved by what he heard. He asked, "Can a satellite navigation system be built with 250 billion?"
"If you hadn't said this, I really wouldn't have believed it."
Wang Haoran smiled and said, "Wait until I make a comprehensive plan for you to see, you will definitely support my idea."
Wang Haoran bid farewell to his leader, and after returning, he began to personally write the construction plan for the satellite navigation system.
His plan is quite comprehensive and detailed, without any empty talk, but full of practical information.
He wrote out all the technical difficulties. Of course, it is not difficult to list the technical difficulties, but the difficulty lies in proposing solutions to the problems!
In Wang Haoran's report, he wrote out all the solutions to the technical difficulties required by the current satellite navigation system.
The most critical component of a navigation satellite is the atomic clock. If we want accurate navigation, we must develop an atomic clock that can tell time more accurately.
Although Longguo already has atomic clocks, they are the results of more than ten years ago and are far from enough to make satellite-borne atomic clocks.
In the previous life, it was because of the bottleneck of atomic clocks that the Beidou satellite navigation system was delayed for more than ten years.
For now, the best atomic clocks in the world are still in the hands of the Lizards. But if you want to buy them from them through free trade? That is simply impossible.
They will not hesitate to use any means that can slow down your development.
So, the atomic clock has to solve its own problem.
So, how to develop domestic atomic clock?
In his report, Wang Haoran explained his research ideas in detail.
He even drew his own designs.
An atomic clock has two core components.
One is a microwave cavity and the other is a spectrum lamp.
The microwave cavity designed by Wang Haoran is only the size of a film, but several grooves must be punched at specific positions inside it. Moreover, these grooves are very particular and must be punched just right to achieve the best effect.
Wang Haoran directly gave the optimal groove design simulated by computer software.
This design allows the rubidium atomic clock to maintain high stability and make it more compact.
Maybe some people would say, why must it be miniaturized?
Because this clock is used on satellites.
If the size of my country's first atomic clock is more than a person tall, it cannot be used on satellites at all.
The second technical difficulty is the rubidium spectrum lamp.
Generally speaking, the light intensity of the spectrum lamp fluctuates greatly. If the light intensity fluctuates greatly, the rubidium sample will be consumed quickly, and it is impossible to work in the vacuum environment of the satellite.
This requires a new type of rubidium spectrum lamp.
Wang Haoran also gave a perfect design idea...
In short, in Wang Haoran's report, it is clearly explained how heavy rockets, navigation satellites and the entire navigation satellite system can be networked in space to work better.
After he finished writing the report, he read it again, made some revisions, printed it out, bound it into a book, and handed it to the designer.
When the designer received it, he saw it and was surprised to find that it was as thick as a finger and looked just like a book.
He tried to read it himself.
At first, he didn't expect to understand it.
Because he doesn't understand these overly professional things at all!
However, he didn't expect that he actually saw it clearly and understood it.
Because the report was written in a very easy-to-understand manner, he could easily understand the other party's intentions.
Overall, the leaders believe that this plan is feasible.
Therefore, the leader called together experts in aerospace and satellites and asked them to give their opinions on the plan.
Naturally, Mr. Qian was among the experts summoned.
Mr. Qian is a famous rocket expert and the father of the missile.
When it comes to launch vehicles, he is naturally an authority.
He read the design part of the heavy-lift launch vehicle written by Wang Haoran, and was very impressed by the design plan of the hydrogen-oxygen engine proposed by Wang Haoran.
Hydrogen-oxygen engine is a trend in engines of new launch vehicles in Europe and the United States.
People are working on the research of this type of engine, and it has already appeared in practical applications.
However, there are many technical difficulties in hydrogen-oxygen engines.
For example, the combustion chamber of a hydrogen-oxygen engine has a very high pressure and a large heat flow. If the inner wall thermal protection problem cannot be solved, it will easily lead to cracks in the inner wall, thereby destroying the entire engine until a violent explosion occurs. This requires the use of alloy materials with high toughness and good fatigue resistance.
The best alloy material for the combustion chamber is silver-zirconium-copper alloy, and the refining of this alloy is also a great technical difficulty.
In addition, hydrogen-oxygen engines use a lot of high-temperature alloys and titanium alloys, and their molding and processing requirements are also quite high, requiring sophisticated processing technology. This also needs to be broken through.
How to break through?
Wang Haoran explained it clearly in his report.
In addition, the auxiliary parts of the combustion chamber, such as the turbine rotor, must not only withstand the high temperature of 600 degrees but also the ultra-low temperature of hydrogen and oxygen in the industry, and at the same time, they must maintain high-speed rotation and long life. This also requires the selection of better alloy materials and precise processing technology.
Wang Haoran also explained this thoroughly.
The thermal environment faced by hydrogen-oxygen engines is quite complex.
Liquid hydrogen has a temperature of 252 degrees Celsius. Most materials become very fragile at such low temperatures. The temperature of hydrogen burning in oxygen can reach 3300 degrees Celsius. There are very few materials that can withstand such extreme temperature differences.
This also poses a very high challenge to the structural design of the engine and its pipelines.
It is precisely because the development of hydrogen-oxygen engines is so difficult that even a company like Jusa has experienced countless failures during the development process.
Every failure is very tragic. The explosion will blow the entire engine to pieces. Even if you want to see what mistake you made, it is impossible!
The solution given by Wang Haoran is actually quite simple.
The first is: the storage of hydrogen-oxygen propellant in the hydrogen-oxygen engine is insulated using a thermal insulation coating.
The propellant storage chamber is open to allow air to leak out and release pressure.
However, if it is not sealed, the low temperature of the hydrogen-oxygen propellant will cause the air to condense at the jet nozzle, resulting in ice crystals on the outside, which may even collide and cause an explosion.
The solution is simple: use helium to blow out the air from the jet nozzle, thus isolating the outside air and ensuring safety...
After reading Wang Haoran's report proposal, Mr. Qian applauded.
He said to the leader: "Leader, Comrade Haoran's plan is as if he has already practiced it once."
“I think it’s totally feasible!”
"I don't understand other things, but I understand rockets!"
"We have tried to produce hydrogen-oxygen engines before, but we gave up in the end because they were too difficult."
"But now, I think that according to Comrade Haoran's plan, I think we can definitely build a qualified and useful hydrogen-oxygen engine."
Hydrogen-oxygen engines are difficult and dangerous to build, but their advantages are also very obvious.
Its biggest advantage is its high specific impulse performance.
The so-called specific impulse refers to the thrust that can be generated by unit mass of propellant.
The higher the specific impulse, the higher the transport efficiency of the rocket, and the more payload it can carry into space.
The second superior performance of the hydrogen-oxygen engine lies in its efficient combustion rate.
The hydrogen-oxygen combination combustion process is very complete, and the combustion product is only water vapor. There is no solid residue and no carbon deposit problem, which is conducive to the reuse of the engine.
In addition to Mr. Qian's full affirmation of the heavy-duty rocket proposed by Wang Haoran, other satellite experts also fully affirmed the design plan of the navigation satellite proposed by Wang Haoran.
Everyone agreed that the construction of the global satellite navigation system could be advanced according to Wang Haoran’s idea.
The leader was also very happy and said, "I heard that the Squids are working hard to promote their global satellite navigation system."
"We just have to compete with them!"
"They themselves boast that once their global satellite navigation system is completed, they will have an overwhelming military advantage."
"They can attack wherever they point their finger, and they have tight control over other people's ability to counterattack... I just don't believe this!" (End of this chapter)
