Chapter 562 Take Care of Yourself Before Talking About Others!

Xinghai Group, headquarters base.

On the side of the nearby road, a car was parked, and there were two yellow-skinned middle-aged men in the car.

The car is rented and changed every day.

These two people are not from the Hua country, but from the Han country, but belong to the intelligence personnel of the Ugly country.

These two intelligence agents didn't mean to hang out here, they came to monitor the intelligence activities of the Xinghai Group's headquarters base.

A roaring sound woke them up, and they immediately looked in the direction of the sound with vigilance.

They know that the Xinghai Group has been developing new technologies and has robbed the relevant departments of Ugly Nation many times. Therefore, the headquarters sent them to collect intelligence so that Ugly Nation can better deal with this situation.

"Hey bro, listen to this voice."

Generally speaking, when the afterburner turbofan engine is tested with afterburner, the noise can be as high as 120 decibels or even 140 decibels. This sound level is equivalent to the noise level of a rocket launch, which is very noisy.

In order to reduce the impact of noise on the surrounding environment and staff, various measures are usually taken, such as installing sound insulation equipment inside the laboratory.

Xinghai Group's 02J engine is really too big, no matter how good the design is, the noise is still very high, and it is still transmitted from the test site, and people within one kilometer near the laboratory can still hear it if they listen carefully.

"Well, yes, after guarding for so long, I finally heard some movement. What is this Xinghai Group doing? The movement is so loud!"

"Listen to this sound, it may be testing a new type of aero-engine. Generally, the sound is not so loud. Judging from the direction of the sound source, it belongs to the third base of the Xinghai Group. This workshop, according to the information we have, is an aviation engine. engine lab."

"That's right, let's report to the higher-ups. After guarding for so long, we finally have some useful information."

The two exchanged silently and recorded the information at the same time.

There are strict protection measures around the Xinghai Group headquarters base, and the security force is very strong. It is very difficult to get close to the base. They can only analyze by observing the passing vehicles.

Sometimes, they pretended to be tourists and asked the employees of Xinghai Group for some information, but the employees of Xinghai Group were very vigilant and couldn't get any information.

They also tracked down a Xinghai Group employee, and rented the house opposite his room to be a neighbor, trying to make a good relationship, but before the information was obtained, he moved to the Xinghai Group employee's residence, leaving them in vain thought.

However, they changed their target and finally became the "neighbors" of Xinghai Group employees. They set up several parties and got some information after they got drunk.

It is becoming more and more difficult to find targets now. The employees of Xinghai Group either live in dormitories or live in new houses. It is impossible for them to get in, let alone the employee system of Xinghai Group. squeezed himself into the cell.

I heard that many colleagues were discovered.

Nowadays, Xinghai Group rarely recruits socially. Social recruiters need to investigate their work background, primary and secondary school experience. Maybe they can fake academic qualifications and work experience, but some things cannot be faked, so they can only give up the method of mixing into the employee system. The group secrecy system is done too well.

A few minutes later,

The two drove away from the scene, returned to the place where they lived, and reported the situation collected this time.

Apart from these two people, many people heard the sound of Xinghai Group's engine test.

That night, it was reported by the media: "Xinghai Group is conducting a mysterious test, and a huge roaring sound comes from the base, like an aero engine test. It is possible that a new type of aero engine is being developed, and it may have been successfully developed."

The next day, when Mu Yang went to work in the company, the public relations department reported the matter to him.

Mu Yang glanced at it, and dismissed it. He let the public relations department ignore it and let the outside world guess at will.

After a while, the engine test will be carried out, and there is no way to hide it, unless another layer of soundproof room is added, which is too troublesome.

When the ground-effect aircraft was tested, that guy was so big that it was impossible to hide it during the test.

A few days later, Han Li reported to him the reason why the engine ignition test afterburner room temperature was too high:

"Chairman, the problem has been found out. The temperature of the afterburner rises too fast. The high temperature resistant coating is not enough to resist the high temperature above 1700 ℃. The thickness of the 02J coating is much thicker than that of the 01J. If it is thicker, it may take Cracks, other than that, we have no good solution, unless there is a better high temperature resistant coating technology."

Mu Yang thought for a while and asked, "How many afterburners do we have without spray coating?"

"There are three more engines. We have developed a total of five engines for testing."

"Okay, I'm thinking of a solution, and you guys have to figure it out a bit more to see if there is a good solution."

"OK."

Han Li nodded respectfully. He planned to go back and hold another special meeting to jointly tackle this technical problem.

The structure of the engine cannot be moved, it has to be redesigned, and the structure of the engine is already very reasonable, the current problem is not in the structure;

The cooling system cannot be moved, and the metal 3D additive technology is used to manufacture the hollow structure. The cooling system has been raised several grades, otherwise the temperature will rise faster.

Worry!

Han Li left the chairman's office with a worried face.

After Han Li left, Mu Yang looked for high-temperature-resistant coating technology from the system store.

There are many such technologies, such as thermal barrier coating (TBC), alumina coating, anti-corrosion pit coating, ceramic coating, fluorocarbon coating, silicon carbide coating, etc.

Like the afterburner, the engine vibrates greatly when it is working, so it is not suitable to use ceramic coating, because it is too brittle.

At present, the company's engine uses nickel-based high-temperature alloy coating technology, which has good toughness, but it should not be too thick, and the high temperature resistance is limited, and it can withstand high temperatures of up to 1780 °C.

This high temperature resistance is very powerful. Generally speaking, common high temperature resistant coatings can withstand high temperatures of about 1000°C, and coatings that can resist high temperatures above 1500°C are relatively rare.

For example, silicon carbide coatings can resist high temperatures up to 1600°C, and molybdenum coatings can resist high temperatures up to 1700°C.

The current situation of Muyang Comprehensive Company, after looking for two hours, found a coating technology, molybdenum-tungsten coating technology, the toughness is slightly worse than nickel-based superalloy, but the high temperature resistance can reach the terrifying high temperature of 2000 ℃.

In addition, there is no coating material with higher temperature resistance.

Mu Yang believes that even if the reading system is upgraded to level 8, this high-temperature-resistant material will not make a breakthrough unless new high-temperature-resistant elements are incorporated.

In other words, there is a special cooling technology.

"Even if this material can withstand a high temperature of 2000°C, its toughness has decreased and it is easy to crack. Worry!"

Mu Yang sighed, the temperature resistance of the light-resistant coating is not enough. The afterburner is not only high temperature, but also high pressure, and the working conditions are very complicated, so the requirements for the toughness of the coating are very high.

The company's rocket engine also uses the same coating material. Experiments have found that the coating cracks. If it is replaced with a slightly inferior molybdenum-tungsten coating, the temperature resistance may be achieved, but the service life will be greatly reduced.

He thought about it carefully for a while, and felt that the risk of using molybdenum-tungsten coating technology was still too high.

"Hey, why don't I think of a way from the cooling technology?"

Suddenly, Mu Yang thought of another plan.

The structural material of the combustion chamber is hollowed out, and cooling air or cooling liquid can pass through. His inertial thinking is to solve the problem from the high-temperature resistant coating, but he never thought about finding a solution from cooling liquid or gas.

If there is a cooling gas or cooling liquid that cools well, the original coating scheme does not need to be replaced.

"Look around, it's a dead end."

Mu Yang patted his forehead, even if he didn't use the reading system, he quickly thought of fully synthetic liquid metal, helium-3, liquid helium, etc.

The cooling gas currently used in the engine hollow is the inert gas nitrogen, which can be used for circulating cooling.

But something better than nitrogen, like helium-3, or liquid helium in greater concentration.

At the same concentration, helium-3 has a better cooling effect than helium.

Even, the cooling effect of helium-3 gas is better than that of liquid helium.

If it is liquid helium-3, the refrigeration capacity is even stronger.

Helium-3, also known as 3He, is an isotope of helium, a rare gas, and has a wide range of applications in nuclear physics, low temperature physics, superconductivity and other fields.

Because it is a superfluid, it can flow without internal resistance and has extremely high heat transfer efficiency.

Therefore, in low-temperature experiments, lower temperatures and higher refrigeration capabilities can be obtained using helium-3.

However, helium-3 is a radioactive isotope, which is more difficult to prepare and store, requires a higher level of technology and special safety measures, so it is rarely used.

These factors have led to the very high price of helium-3, generally only a few laboratories and research institutions can afford it.

According to the international market conditions, the price per liter of liquid helium-3 is usually more than one thousand dollars. The problem is that it cannot be bought, so sometimes the actual price is outrageous.

In terms of liquid metal, it is not suitable for 02J engines, because the hollow holes are smaller, and the fluidity is poor, but the cooling effect is poor.

Mu Yang looked at the Reading System store and directly searched for cooling gas.

Sure enough, there is the development technology of helium-3, and it is better to see the technical introduction than other cooling gases.

Soon, he found a technology that made helium-3 easier to manufacture and more convenient to store.

Achievement point requirements: 50 points!

There are not many achievement points required, so I bought it without much hesitation.

After absorbing the technology, Mu Yang discovered that the equipment structure is not too complicated, and the main manufacturing materials and quality requirements are stricter.

The time was a bit urgent, Mu Yang directly realized the data, and then handed it over to the relevant departments of the company to let them quickly develop and produce it. If it is fast, it can be made in more than ten days.

The company has materials and spare parts, metal 3D additive technology, and already has the ability of rapid manufacturing.

If you switch to a general machinery company, it may not be able to develop it within half a year.

At the same time, Mu Yang told Han Li the solution, asked him to keep an eye on the manufacture of Helium-3 equipment, and told him some safety points.

The hollow cooling hole of the afterburner can withstand high temperature and pressure, and it is possible to store helium-3 radioactive gas.

Helium-3 itself has low radioactivity and is not as harmful as uranium and plutonium in nuclear power plants. Of course, if exposed to high-concentration helium-3 gas for a long time, it will cause certain harm to the human body.

Mu Yang also considered this point, and felt that the afterburner cooling system could store high-pressure and high-temperature gas, so it would be no problem to store semi-liquid helium-3.

If it does leak, it quickly dissipates in the air.

Time passed like water, and ten days passed quickly.

Good news came from Han Li that helium-3 equipment was successfully manufactured and helium-3 gas could be produced.

Two days later, the 02J afterburner was replaced with helium-3 gas, the concentration of which was semi-liquid, waiting for the test.

May 31,

AN05-02J engine conducts the second ignition test.

This time, the previous ignition test was normal.

Before adding force, Han Li and Mu Yang found that the temperature of the parts cooled by the helium-3 gas had dropped a lot. They were pleasantly surprised, which meant that the effect was good.

"Start adding power, pay attention to the temperature."

Increase the afterburner slowly from 10%, and stay for three minutes to record the data.

When the afterburner reaches 30% again, the temperature of the afterburner reaches 1650 degrees Celsius in just a few seconds and the alarm starts. The material performance drops sharply at this temperature, and the combustion chamber will be beaker directly in this temperature range for a long time.

Now, after running for about 1 minute, the highest temperature is only 850°C!

When Mu Yang saw this temperature data, he wanted to applaud, so he held back and let Han Li continue the experiment.

When the afterburner reaches 50%, the temperature rises relatively quickly, and the highest temperature is only 1010°C.

This temperature, if it is a general steel, is the austenitization temperature, that is, the internal structure begins to change.

Han Li was pleasantly surprised, and looked at Mu Yang: "Chairman, do you want to try to continue to work harder?"

"Go on, let's see what the maximum 60% is?"

Han Li nodded solemnly and gave the order.

At this time, all researchers are very excited.

The flame of the nozzle is getting longer and longer, and it is already red, and the noise "huhu" explodes.

When the afterburner is 60%, the thrust has reached 108 tons, and after one minute, the highest temperature has reached 1150 ℃.

This temperature doesn't matter at all for the high temperature resistant combustion chamber.

If it is switched to a fighter jet, the afterburner can be turned on continuously, and it is not afraid of burning out the engine combustion chamber at all, but it is afraid of burning out the vector nozzle.

Mu Yang said to Han Li with satisfaction: "Come on, the engine has reached its limit, and the fuel is almost used up."

"OK."

Han Li was ecstatic.

After a while, the test data came out.

In the test, the afterburner operated very stably, and there was no leakage of helium-3 gas, and the use effect was very good.

Mu Yang expressed his gratitude to Han Li and other engineers: "The success of this experiment is inseparable from everyone's efforts and contributions.

The performance of the 02J afterburning engine is very good, which will provide strong support for our future aerospace industry. "

Everyone applauded enthusiastically. In the final analysis, the chairman personally solved the cooling problem, and the effect was remarkable.

"At the same time, we must continue to work hard in the future to further improve the performance and stability of the engine." Mu Yang added, he found that the current self speaks a bit bureaucratic.

In the past, he hated bureaucratic people so much, thinking to himself, he probably got used to it, and he would become someone hated by others in the future.

Fortunately, all the cakes I drew for the employees have come true.

Han Li and the other engineers continued to applaud. The engine was ignited successfully. They were all very excited and excited, looking forward to the moment when the large aircraft ignited and took off.

After the chairman left the test site, they continued to summarize the test process and check the damage to the engine parts.

Xinghai Group's experiment this time has attracted more people's attention.

Some time ago, it was not very sure, and many eyeliners were sticking to the periphery. I believe that Xinghai Group will try again soon.

In the past ten days or so, they kept their ears up all the time, for fear that they might miss a crucial situation.

In the first few days, I didn't wait until my ears were covered with calluses.

Fortunately, they have undergone special training and have strong perseverance, and they finally made it today.

Many eyeliners have confirmed that the Xinghai Group is testing a large-scale aero-engine test, and reported the news upwards.

Not only these eyeliners, but the passing people also guessed some.

As the news spread, more and more people began to pay attention to Xinghai Group's aerospace engine test.

Some media and experts began to analyze and speculate, trying to reveal the true purpose and significance of this test, and speculate on the performance of Xinghai Group's new engine.

For competitors, such as the top management of RR and GE, it is very worrying.

The XH-AN05-01 aerospace engine has caused the two companies to lose a lot of orders for civil aviation aircraft, and it was snatched by SAIC.

The spokesperson of the relevant department of the ugly country said: "Condemn Xinghai Group for conducting secret experiments. We believe that Xinghai Group is very likely to conduct experiments that endanger human beings, and it should be announced to human beings."

A spokesman for the Xinghai Group denied the accusations and said their experiments were in full compliance with international laws and ethics and would not pose a threat to anyone.

At the same time, they also appealed to the relevant departments of the Ugly country to stop making unwarranted accusations against them, not to try to interfere with their normal research work, and they would not accept such behavior of covering up moral hats indiscriminately.

Mu Yang, on the other hand, was so bored after watching too many verbal fights, so he directly stated: "Take care of yourself before talking about others!"

Such a statement caused laughter from netizens all over the world.

However, judging from the speeches of Mu Yang and Xinghai Group, Xinghai Group is undoubtedly conducting a new type of aero-engine test, and some international airlines and ZF departments have also begun to pay attention to and track the behavior of Xinghai Group, hoping to obtain useful information and technology from it. .

This test has also aroused extensive discussions in the global scientific and technological circles. The XH-AN05-01 aero engine is very abnormal. Is XH-AN05-01 aero engine coming out with an even more abnormal engine?

Just a few days later, the news of the Xinghai Group's test of a large engine has not yet calmed down, causing another big commotion.

Xinghai Group signed an investment agreement with Jincheng to establish a seawater desalination test base on the beach opposite the Nangang Industrial Wharf.

The investment scale is 2 billion yuan, and the first phase covers an area of ​​500 mu.

It seems that the scale of investment is not large, but the significance of the project has caused the media and experts to start analysis and speculation.

Is Xinghai Group planning to solve seawater desalination?

Jincheng got the consent of Xinghai Group, and ZF responded to the media reporter's interview: "This cooperation between us and Xinghai Group is of great significance, and it may be an important step in the desalination of Shanghai water in human history.

The purpose of Xinghai Group to establish a seawater desalination test base is of course to solve the problem of fresh water for human beings.

At present, Xinghai Group is stepping up research and development of related technologies. If the test is successful, it will supply fresh water resources to northern my country. "

There is no more news. Xinghai Group has not disclosed the desert greening and east-to-west water diversion projects to Jincheng ZF.

In Mu Yang's words, publicity can only be made after the successful development of related technologies and equipment, and it is not appropriate to be high-profile at present.

But if the east-to-west water transfer plan is announced, it is estimated that the higher-ups will find him first to talk.

One month has passed, and the manufacturing progress of the magnetic desalter is relatively fast, but it occupies a very large area and the development cycle will be relatively long.

Mu Yang planned to inspect the test base in a few days. The Xinghai Group moved very quickly, and the construction drawings had not yet been released. An engineering company had been entrusted to start leveling the land. Jincheng ZF also approved this approach.
