At present, Qin Ru has many kinds of materials, and the main one is the data that Chen reverses according to the materials on the market.

These include special steels for military use, and hybrid alloy materials for aerospace.

At present, the world's special steel, the maximum strength is the steel with a strength of 1200MPa used by Russia for the God of the North Wind, which can allow the God of the North Wind to sail on the bottom of the sea at a depth of 1,500 meters.

The strength of Ohio-grade special steel in the United States is 980MPa.

Huaxia's special steel, the best, is just breaking through 700MPa.

That's the gap.

Whether it is steel or the alloy of the shell, it needs to be reinforced on top of MPa (megapascal-pressure).

Qin Ru's current strength for the green twin shell is 760MPa.

But it still can't withstand the problems of sonic flight.

If you want to achieve this, you need to at least increase the strength to 950 or more.

The strength of 950MPa is currently mastered by only a few countries in the world, namely the United States, Japan, Russia, France, the United Kingdom, and Germany.

Moreover, 950MPa strength steel is generally only used in one field, that is, the military field, especially nuclear submarines and aircraft carriers, which will be used in large quantities.

Why does Japan's Soryu APP submarine make Huaxia so vigilant? It is because the shell of the Canglong APP submarine is made of special steel with a strength of up to 1000MPa, coupled with all-electric propulsion, the noise is reduced to below the sound of the ocean.

This is not blowing, the Ohio class uses only 980MPa, while the Canglong uses 1000MPa.

Although there is only a gap of 20, in the field of submarines, every little gap is a very big progress.

Since the 70s to the present, Huaxia has lasted more than 40 years, from 210MPa to 740MPa now, even if it is unpublished data, but according to the assessment, the maximum strength of special steel mastered by Huaxia will definitely not exceed 850MPa.

This is why China's strategic nuclear submarines, nuclear attack submarines, have always lagged behind all countries in the world by a generation.

The Ohio class is a product of the 80s.

What now? With American technology, dare to say that it cannot surpass the 1200MPa of the God of the North Wind?

How can it be?

It is precisely because of this that China is one or even two generations behind in the field of nuclear submarines.

At present, the strength of the special steel on Huaxia's aircraft carrier is about 850, but the data has not been released, no one knows, and it can only be evaluated according to the situation in Huaxia.

1000MPa strength steel, Qin Ru can be manufactured, not to mention 1000MPa, even if it is doubled, Qin Ru can also be manufactured.

However, it is not necessary and will not be manufactured.

At present, the special steel of various countries can be said to be mixed steel, which is based on the steel and adds other metal elements to enhance the strength of the special steel.

Such a method has indeed reached the limit, and it will not exceed 1500MPa at most.

Unless it's to find new materials.

Qin Ru is currently looking for new elements in the ocean, and the new materials it has made can reach a strength of more than 5000MPa.

This is also the reason why Qin Ru is so confident.

5000MPa is the most basic, and in the memory of the highest Zhuchenfan, the strength can reach 200000MPa.

However, if you want to break through more than 10,000 MPa, you need a lot of new elements, and those new elements can only be produced and mined in space.

This is also why in many science fiction worlds, there are some special materials that can only be produced in the absence of gravity in space, and the materials produced can resist the attack of the battleship's main gun.

Here's why.

I tested it more than twenty times, and it still ended in failure.

Qin Ru sat on the side.

Looking at the unfinished green twins, I don't know what to say.

With the current influence of the blue company, 760MPa is already the maximum limit.

If you go up again, there will be problems.

It's not the problem of the blue company, it's the problem of the military.

The strength of 760MPa special steel is already the top existence in the Chinese military.

Now in the hands of a civilian company? What will be the result?

If you dare to get more than 800MPa, I believe there will definitely be big trouble.

Although this is not very likely, it is not small.

But Qin Ru won't gamble, bet on the military's forbearance, at least, Qing Shuang is not worth Qin Ru's bet.

What do you say, in terms of setting, it is a global strategic transport aircraft.

Even if it is developed and Huaxia takes a fancy to it, there will not be many orders.

To a certain extent, in the future, Qing Twins will be used by Qin Ru himself.

As for whether the others are sold to Huaxia or to other countries, the probability is a question.

"Tatsu, do you have any suggestions?"

Qin Ru raised his head.

"BOSS, 860MPa can achieve 1200 km cruising capacity!"

Qin Ru rolled his eyes, "I naturally know, forget it, reduce the speed for the time being, and divide it into two projects for me, an ordinary type, with a shell strength of 760MPa and a speed of 750 kilometers!" The second, the enhanced strategic type, the shell 950, the speed is 1500 km/h! ”

"Yes, BOSS, what is the code name?"

Qin Ru hesitated for a moment, "Qing Shuang!" The ordinary type is Qingshuang No. 1, and the strategic type is Qingshuang ......"

Suddenly thinking of something, Qin Ru pondered for a moment, "Strategic, Qingtwin No. 0!" ”

Qin Ru originally wanted to say Qingshuang No. 2, but thinking about the possibility in the future, Qin Ru set it to zero.

"How much time will it take to temporarily allocate productivity and get me a Qingshuang No. 1 testing machine?"

"Expected to be one hundred and twenty days!"

Qin Ru frowned.

Four months?

"The large factory is not yet finished, and the underground production base cannot make large transport aircraft!"

Chen's words made Qin Ru understand.

Nodding helplessly, "That's it!" In the process of getting out of the test machine, the military will not know about it for the time being, and the personnel will be transferred from the production department, and the military production will be kept secret for the time being! ”

"Understand, the project has been set up, and the transfer of personnel has begun!"

The reason why Qin Ru raised the speed of Qing Twin to the speed of sound.

Mainly, Qin Ru plans to use the green twin to launch satellites.

The strength of the green twins allows the aircraft to fly to low orbits.

At that altitude, the launch of satellites is achievable.

Back then, the USSR tried.

However, for many reasons, it was finally cancelled.

With Zhu Chenfan's memory, Qin Ru is very clear about the problems he thinks about from the perspective of the country.

Qingtwins is the power reserved for the future blue company.

By that time, Qin Ru had built advanced quantum satellites.

The blue will not be subject to any people, countries, or forces.

Not only communication, transmission, including combat, is also achievable.

Now countries are building their own space-based weapons systems.

Similar to the scepter of God in the special forces movie, it is actually not difficult to achieve.

In other words, the United States is already in a high orbit, and it is not necessary that it has deployed God's scepter space-based weapons.

What Qin Ru prepared for the blue company was a space-based weapon.

Space-based weapons are certainly unlikely to be launched from any space launch base.

You can only launch it yourself, and in order to ensure secrecy, it is almost impossible to launch a rocket.

So, the green twins were born.

The green twins can fly to low orbit and drop satellites, if they are enhanced to some extent, and their sealing is enhanced.

It is not impossible that the green twins can fly to the middle orbit.

At that time, how many satellites to launch is a matter for Qin Ru to decide, and other countries will not even be able to discover these satellites/.

After all, there are more than 100,000 satellites operating in Earth orbit.

Even the United States can only focus on monitoring more than 20,000 of these satellites.

In addition, there are more than 30,000 abandoned satellites that have lost their function, and Qin Ru will not be noticed if he puts hundreds of satellites into them.

"Uncle?" In the office, Li Shiying was stunned.

But still took the phone.

"Hello? Uncle, is there something wrong? ”

"Shiying, something happened to my hometown......"

Li Shiying frowned.

At this point, the door was pushed open.

Li Ya walked from outside in a panic.

"Uncle, Li Ya is here with me, well, I know, I'll go over right away!"

hung up the phone, Li Shiying was solemn.

"Cousin, is this true?"

Li Shiying was stunned, but she thought that Li Ya was the main lineman of the Li family.

Not surprising either.

Shaking his head, "I don't know, I'll fly over and take a look right away, you hand over the work, and go back with me!" ”

"Well, I know, I'll hand over the work right away!"

Li Ya didn't stop, turned around and ran out.

"I'm Li Shiying, help me charter a plane, take off in three hours, and target Sioux City!"

"Okay president, I'll contact China Southern Airlines right away!"

Li Shiying nodded and hung up the phone.

Just now, my uncle, who is Li Shiying's own family, called.

said that his hometown was blocked, and many old people in his hometown were blocked inside, and all that area was blocked, and at least more than 5,000 people were blocked inside.

My uncle was doing business outside, and when he received a message, he called his hometown, but he couldn't get through.

I found a lot of people, but I couldn't ask what the situation was.

A person suddenly remembered Li Shiying.

Then the uncle could only call the United States and ask for Li Shiying's phone.

"Chen, investigate the situation in XX Village, XX Town, Suzhou City!"

Li Shiying thought of something, raised her head and said.

"Okay President!"

A picture is presented.

The situation of several villages is all on the screen.

Satellite imagery.

It can be seen that on several roads outside the village, the armed police have blocked all of them, and there are also a large number of armored vehicles, and the police have blocked all the roads leading to this place, blocking up to 50 kilometers, and a large number of people can be seen evacuating here with the assistance of the police.

"What's the situation?"

Li Shiying was stunned.

"According to the network data of the local police, it is said that there is a chemical leak here, which has polluted most of the Taihu Lake, and several surrounding towns and more than 50 villages have been included in the evacuation list, and the Sioux City government has ordered all the subordinate police departments to be mobilized, and there is already a battalion-level army leading here!"

"Chemical spills? Find out, what exactly? ”

"President, I'm sorry, the local network is completely blocked, and I can't investigate more, but what can be told to the president is that most of the people in these villages are fine, they are all concentrated, if the rescue or go deeper, what is the problem?"

"Inform the Azure Third Brigade to transfer two squads, fully armed, and follow me!" Li Shiying pondered for a moment, and asked Chen to pass the order to the blue security side, and Li Shiying's authority could mobilize three combat teams.
