bonanza

David Weber thought for a while and said, "This is not difficult!"

The United States has been deindustrialized for many years. Although it still looks rich on the surface, its roots are rotten.

The gap between the rich and the poor is widening and the unemployment rate is very serious.

Americans never reflect on it. They have always pushed their responsibilities to foreign countries.

That's what they did when they were dealing with the Japanese.

And it works.

At the critical moment, he took a breath of success.

Eventually won the Cold War and dominated for decades thereafter.

What's more, one company has already been sanctioned, and I don't care how many more companies are sanctioned!

"Which companies do you want to include?" David Webb asked.

"Of course, the bigger the better, the more the better!" Yang Dongsheng smiled.

The first category of companies that Yang Dongsheng intends to expand into are state-owned enterprises represented by Aerospace Corporation and Electronic Technology Corporation.

The names of these companies are big enough, and the industries involved are also very sensitive, enough to provoke XX's nerves.

The second category is the private enterprise represented by the company with the boss.

This kind of enterprise is what Yang Dongsheng is most worried about, and it is also the most likely to backstab them.

The third category is scientific research institutions represented by wind tunnel bases and high-altitude test benches.

The fourth category is universities represented by XX University of Technology and XX University of Aeronautics and Astronautics.

These enterprises and institutions represent the future of the entire XX, including them all, Yang Dongsheng does not believe that XX can bear it.

After paying the deposit, it will take time to operate, and the sanctions against Dongsheng Group will take effect first.

The first to be affected is the civil aviation engine of Dongsheng Heavy Industry.

This is Dongsheng Heavy Industry's large bypass ratio civil aeroengine derived from their previous military core engine with small bypass ratio.

It is mainly used for single-aisle mainline airliners—that is, C919, Boeing-737, and Airbus A320.

This is currently the largest civil aviation airliner in use, accounting for more than 90% of sales.

At present, this engine is undergoing airworthiness certification work in Europe and the United States-not only civil aircraft must obtain airworthiness certification, but aircraft engines must also obtain certification.

The United States made it clear that out of "national security" considerations, Dongsheng Heavy Industry's engines are excluded from the scope of use of civil aviation airliners.

If the Americans do this, the Europeans will definitely follow suit.

After the public intellectuals got the news, they were excited and rejoiced, and they couldn't wait to tell the news!

Yang Dongsheng has always been curious, why are these idiots so excited?

If the United States doesn't use their aero engines, will their aero engines be dead?
It is not certain who will sanction whom!

The two major aircraft manufacturers Boeing and Airbus can choose not to use this engine.

However, the large aircraft independently developed by China will definitely be equipped with this engine, at least partially.

The thrust, fuel efficiency, and emissions of this engine are far superior to the current CFM-56 engine.

The operating cost of an aircraft using this engine will definitely be much lower than that of a passenger aircraft equipped with a CFM-56 engine.

According to statistics, since the establishment of commercial transport airlines, the average profit margin of global airlines is only about 1%.

There are a lot of comments on the Internet about how the airline saves one olive, which saves the company hundreds of thousands of dollars in chicken soup.

As long as there is a comparison, the airlines themselves will choose Dongsheng Heavy Industry's aero engines, otherwise they will be eliminated.

If Boeing and Airbus aircraft are not equipped with Dongsheng Heavy Industry's aeroengines, they will also be eliminated.

At that time, without Yang Dongsheng's efforts, they will push it by themselves.

However, with the new round of sanctions, Yang Dongsheng found that his long-stalled ability began to improve again.

Since the last time he broke through 6000 kilometers, he has never made a big breakthrough.

This time, Yang Dongsheng went one step further, reaching 6300 kilometers, and finally broke through the nickel-iron layer.

A host of heavier metals appeared in front of me, including niobium, copper, silver, uranium, thorium, gold...

According to the book, in the first few hundred million years of the earth's birth, the temperature was very high, and a large amount of heavy elements were deposited deep underground.

This, in turn, included a large amount of radioactive material, which further heated the Earth's core.

The heavier matter then sinks further toward the center of the earth, forming the core and mantle, while the lighter matter is distributed on the surface, forming the crust.

Yang Dongsheng even guessed that there is an oversized nuclear reactor deep in the core.

Now he has indeed seen a large amount of radioactive substances deep in the earth's core, such as uranium 235, uranium 238, thorium 232...

It can be seen that these radioactive substances with a half-life of hundreds of millions of years, or even billions of years, are slowly decreasing.

At present they can provide very little heat.

Yang Dongsheng guessed that billions of years ago, the concentration of uranium 235 in the core of the earth would be very high, and may even exceed the 3% level of modern nuclear power plants.

There is such a huge nuclear reactor under the feet, which provides huge heat all the time.

The early earth must have undergone severe geological changes, frequent volcanic eruptions, and the ejected magma even carried deadly radiation.

Not suitable for biological survival at all.

After billions of years of development, the current concentration of uranium-235 in the earth's core is only a few tenths of a percent.

This is the period when the earth is most stable, and it is also when the sun is stable.

Under this double coincidence, all kinds of creatures were born on the earth, and human beings were born.

In addition to these radioactive substances, there are also a large amount of rare and precious metals such as gold, platinum, osmium, and iridium deep underground.

Its value is thousands of times that of the total amount of rare and precious metals that Yang Dongsheng found in the earth's crust.

Yang Dongsheng tried to put various substances into the earth's core to decompress them.

Copper and niobium were first produced, which are either more ductile or have a higher superconducting critical temperature.

Hand it over to the No. [-] material team of Dongsheng Heavy Industry for research.

However, the room temperature superconducting material that Yang Dongsheng has always wanted to obtain has never been produced.

Protium, which accounts for more than 99% of the total amount of hydrogen atoms, has only one proton with positive charge and one electron with negative charge. It is the smallest atom.

There are two hydrogen atoms in a hydrogen molecule, and the temperature at which the Cooper pair is theoretically formed, that is, the superconducting critical temperature is also the highest.

According to the calculations of scientists, the superconducting critical temperature of metallic hydrogen may reach 17 degrees.

But the pressure required to produce metal hydrogen is also very high, it is said to reach 450GPa, or 450 million atmospheres.

It is so high that the existing equipment is difficult to meet, and even exceeds the pressure of 370GPa at the center of the earth.

Therefore, countries can only use hydrogen-rich materials to study superconductivity, such as hydrogen sulfide and lanthanum hydride.

The Chinese laboratory has proved that the superconducting critical temperature of hydrogen sulfide is minus 160 degrees Celsius under 192.16GPa.

This temperature is already above the boiling point of nitrogen - 196 degrees below zero, which belongs to high-temperature superconductivity.

The Institute of Chemistry of the Max Planck Society in Germany even used lanthanum hydride to achieve excellent superconductivity at minus 170 degrees under a pressure of 23 GPa.

Yang Dongsheng tried to suppress these things, but found that he couldn't suppress them at all.
