Chapter 986

Mou Guangying is really full of questions.

It's really unexpected that China, which is said to be the wild mainland version in the public opinion of an island, actually has such a world-class aviation special machining tool.

That's all. The key is that this kind of American products, which are regarded as treasures in Europe, Southeast Asia and even Russia, are only mid-range products in Tengfei group.

So much so that the subordinate aero-engine manufacturers don't even want to use it, they can only use it for civil small gas turbines.

What does that mean?

In ceramic materials, especially applied high-strength ceramic materials, Tengfei group is no worse than the relevant enterprises in the United States, and even surpasses in some aspects.

Mou Guangying is right.

The strength of whnb-5 whisker ceramic cutting tool just launched by Materials Research Institute of Tengfei group has reached 7200 MPa, far exceeding 4500 MPa of WG300 whisker ceramic cutting tool launched by green leaf company last year.

In this way, Tengfei group has become one of the few enterprises that master whisker ceramic technology in the world.

According to the past, Zhuang Jianye and Tengfei group's urine, with such a good object, it is necessary to show up and kill all sides. At the very least, it is necessary to kill the small and elite invisible giants such as the green leaf company of the United States, crown themselves as the king, and then hide behind to count money and make a fortune.

This time, however, neither Zhuang Jianye nor the top management of Tengfei group did so. They just took this kind of high-performance whisker ceramic cutting tool as an ordinary imported substitute product, and they never mentioned it again after it was promoted in Tengfei group.

Even brother factories like Chenggong factory and Northwest Airlines factory didn't take the initiative to mention it. It was Huang Feng who found out when they came to Tengfei group to exchange experience that they bought a batch of them to replace them.

The reason why it is so abnormal is not that Zhuang Jianye and Tengfei group have found their conscience and put making money in the second place and upgrading their taste in the first place.

It's because some time ago, the whole Tengfei group, as an entity, was scolded by the head of the headquarters in front of hundreds of scientific research institutes and enterprise representatives.

The reason for this is very simple. Due to an oversight of data, the ceramic material prepared by Tengfei group has become a whisker ceramic tool for Aeroengine machining that now surpasses the green leaf company of the United States, but it has led to the failure of an important scientific experimental research project of the headquarters.

Direct economic losses alone amounted to 3.2 billion yuan.

This is nothing. The key is that the plan of the headquarters to realize the initial installation of anti-ship ballistic missiles before the 21st century and the 10th century may face many uncertainties due to the failure of this scientific experiment.

This is unbearable for the headquarters. After all, during the major incident, the two aircraft carrier battle groups of a foreign power were like two sharp swords. No one wanted to have a second time. Because of this, the headquarters wanted to hold the anti-ship ballistic missile in its hands more than ever.

Just like the Trident in Poseidon's hand, it also let those unscrupulous aircraft carrier battle groups know what it means.

Just because of this, the reason for the failure to be found out is due to the calculation error in the materials of Tengfei group. As soon as the head of the headquarters changed the old design for the elderly, he criticized Zhuang Jianye almost to find a crack in the ground at the meeting.

In this regard, Zhuang Jianye did not refute.

I can't help it. It's too big and important.

How important is it?

Let's put it this way. No matter in terms of theory or technology, it is totally the first in the world.

This is because the scientific experiment led by the headquarters is not different. It is the QXS trajectory that only existed in theory in the past and has not been verified for decades, commonly known as space drift.

The main reason for using this kind of trajectory is that this kind of space drift can make the enemy's air defense and anti missile system unable to accurately predict the impact point of the kill warhead, so as to achieve the penetration of the aircraft carrier body with intensive protection and achieve the operational purpose.

However, if this kind of trajectory is to be realized, there must be a premise, that is, the warhead must have strong high temperature resistance, oxidation resistance and high structural strength.

After all, if you want to realize the trajectory maneuver like floating in water, the speed of the warhead is about Mach 10 at hypersonic speed, and the maximum temperature generated by friction with the atmosphere can reach 2800 ℃.

At such a high temperature, not to mention the general metal materials, even other high-performance composite materials can not bear, because under the high temperature, the vast majority of materials will appear oxidation reaction.

If it's on the ground, it doesn't matter what the general oxidation reaction is. The problem is that the speed of a floating warhead in near earth space can reach a supersonic speed of Mach 10. At such a high speed, the thin air is like a sharp blade, and it's common to cut iron like mud.

The oxide layer is brittle, not to mention a whole block. It is a hole the size of a pinhole, which can be easily penetrated by lethal air, and then it can be directly dismembered like a scalpel.

Because of this, the surface of the warhead, especially the top part of the warhead, must meet the three basic characteristics of high temperature resistance, oxidation resistance and high strength, so as to realize the whole concept of QXS trajectory.Tengfei group, as the leader of high temperature resistant materials and composite materials in the field of aerospace in China, is the only research and development unit of surface shell of water floated warhead.

In this regard, Tengfei group has been able to live up to the expectations of the public. After years of research and experience accumulation, it soon proposed fiber reinforced ceramic matrix composites to solve this problem.

Because after the test, at the high temperature of 2750 ℃, there is only a thin oxide film on the surface of the fiber reinforced ceramic matrix composite developed by Tengfei group, which does not affect the normal flight.

At the high temperature of 1800 ℃, the fiber reinforced ceramic matrix composites developed by Tengfei group can achieve hypersonic flight for more than 300 seconds, and the strength is maintained at 2100 MPa without any oxidation coating.

The temperature of 2750 ℃ is just the temperature when the water floated warhead enters the atmosphere; the temperature of 1800 ℃ is just the temperature after water floated in the air.

It's good at two temperatures, and it can fly at a hypersonic attitude for 300 seconds at 1800 degrees Celsius. If it can be realized, it will be enough to defy any air defense and anti missile interception system in the world. With high-precision guidance system, it's absolutely a trump card in the trump card.

Therefore, the headquarters was very pleased and immediately started to carry out the experimental verification.

So two months ago, a "recoverable satellite" was launched into near earth space by a carrier rocket in the name of scientific experiment at a space satellite launch site.

In order to make the recoverable satellite reach the predetermined speed, it not only accelerates in orbit, but also uses the gravitational catapult effect to make the speed of the recoverable satellite approach the speed of the second universe, that is, it rushes to the earth according to the predetermined trajectory.

At this time, the maximum temperature of the "recoverable satellite" reached 2735 degrees Celsius, and successfully achieved a water drift like jump, and the speed also decreased significantly, but there was still a supersonic speed of about Mach 15. However, just when people felt that the "recoverable satellite" had passed the initial difficult time, and the subsequent two water drift jumps were as easy as a palm, the falling "recoverable satellite" suddenly fell again And then it disintegrates in near space.

So that people in the ground monitoring hall were all dumbfounded!
