The rejuvenation of a great nation: from educated youth to national treasure scientist

Chapter 166 406 Ultra-High Strength Steel [Request Full Order]

For the next period of time, Wang Haoran stayed in the capital.

Of course, he is still busy every day.

He is in charge of the J-10's avionics system. He has to control the direction and progress of the research team and sometimes even has to do it himself.

For example, he personally wrote the aircraft's computer operating system.

This operating system is still based on the Pangu operating system, but it is very different from the operating system on a personal computer. It requires a lot of streamlining, and the system must remain absolutely stable without any loopholes.

Another thing is to take into account the various functions of the aircraft.

Although it is a rewritten operating system, the difficulty is still quite great.

The chips, sensors and other components used on aircraft are also required to be absolutely stable, reliable and durable. These must be comprehensively coordinated and controlled, and many of them need to be redesigned.

All in all, the work is quite tedious.

Although it is tedious, with Wang Haoran around, all the work is proceeding in an orderly manner.

The avionics system is expected to be fully completed by the end of November.

Of course, after it is done, it will take some time to test.

In addition to the avionics system, there is also work on material research and development.

Overall, material research and development has been quite smooth.

In mid-November, Zhang Aimin, an associate professor at the Department of Materials Science and Engineering at Beijing Institute of Technology, came excitedly to find Wang Haoran.

As soon as he saw Wang Haoran, he excitedly said, "Comrade Haoran! It's done!"

"We followed your guidance and worked with Shougang to develop a very strong ultra-high-strength steel!"

Wang Haoran smiled and said, "Tell me slowly, don't be in a hurry."

Zhang Aimin carefully took out a cloth bag from the green canvas bag he was carrying.

When it was opened, a piece of gleaming steel appeared from the cloth bag.

"Comrade Haoran, look, that's it!"

"After testing this type of ultra-high-strength steel, we found that its tensile strength reaches over 1700 MPA and its yield strength can reach over 900!"

"Its elongation is about 30 percent!"

“Whether it’s strength, toughness, corrosion resistance, or fatigue resistance, it far exceeds all the high-strength steels we’ve developed in the past!”

"Using this steel to make the keel and main frame of the aircraft can not only increase the strength, but also significantly reduce the weight of the aircraft!"

"Using it to make aircraft landing gear is much better than the 300M we used in the past."

Wang Haoran took the small piece of steel handed to him by Zhang Aimin and played with it over and over again.

In fact, it is the 80 steel developed by the Dragon Kingdom in the mid-to-late 406s.

The advent of this ultra-high-strength steel has greatly promoted the development of my country's military industries such as missiles and rockets.

Its performance is comparable to Jusa's D6AC ultra-high strength steel.

Before the advent of ultra-high-strength steel, missile shells were very thick to ensure strength, which increased the weight of the missile and reduced the missile's ammunition and fuel capacity.

Naturally, the missile's strike distance will become shorter and its lethality will become smaller.

It was because Jusa developed the ultra-high-strength steel D1960AC in the 6s that its solid missile development was able to advance by leaps and bounds.

It is with the support of this kind of steel that various intercontinental missiles of Jupiter have emerged, and the solid engines on its space shuttles also use a large amount of ultra-high-strength steel.

It is precisely because of the emergence of D6AC that many people realize that steel can be so hard!

For example, the outer shell skin of a general missile may have required at least one or two centimeters, but now only three or four millimeters is enough.

Therefore, the use of ultra-high strength steel in the military is quite extensive.

The reason why Wang Haoran took out 406 steel right from the start was not just for the manufacture of the J-10.

The development of our country's missile and rocket industries is extremely necessary.

"Comrade Aimin, you have worked hard. This time, you have made a great contribution!"

"This material will be of great use in the military!"

Zhang Aimin waved his hand and said, "Ah! If it weren't for Comrade Haoran's guidance, how could we have developed such a good steel in such a short time?"

"The comrades at Shougang are also very happy because, when they were developing this steel, they improved their production process and equipment according to your ideas. Now they can mass-produce this steel."

Developing ultra-high-strength steel is definitely not something that can be achieved overnight.

This is because it involves the improvement and updating of equipment and processes, and some experiments and even laboratories do not have the equipment.

When Wang Haoran gave Zhang Aimin the task of developing ultra-high-strength steel, he also specifically instructed that it must be combined with steel enterprises.

Because only in this way can we quickly transform into large-scale production.

This is also to save time!

Wang Haoran smiled and nodded, saying, "Cooperate well with Shougang! We must speed up the production of this ultra-high-strength steel!"

"Also, let's name this steel 406 ultra-strength special steel!"

Wang Haoran continues to use this name actually to pay tribute to his predecessors in his previous life.

In the past, this 406 steel was not available until the mid-80s.

It was a little late, so Wang Haoran moved it forward.

Zhang Aimin nodded and said, "Okay! Then let's call it 406 special steel!"

“We’ll use this name when we report our results.”

Wang Haoran said: "With 406 steel, we have almost got the main materials for manufacturing the J-10."

"Of course, there are several other important materials that we need to hurry up with."

Wang Haoran was talking about advanced aluminum alloys and carbon fiber composites.

Advanced aluminum alloys are also widely used in aircraft manufacturing.

It is very useful in the manufacture of aircraft skins and aircraft engine parts.

Aluminum alloy is light in weight, strong, tough and corrosion-resistant. Using it to build aircraft can greatly reduce the weight of the aircraft.

And reducing the weight of the aircraft itself is very important.

Only in this way can the aircraft carry more fuel and more ammunition, fly faster and farther, and have greater lethality.

The new generation of carbon fiber composite materials are as strong as ultra-high-strength steel, but very light. If used in large quantities in aircraft manufacturing, they can also make aircraft lighter.

After Zhang Aimin reported to Wang Haoran, he went back and wrote a final report. Of course, in the report he wrote, he and Wang Haoran were listed as the leaders of the research project.

Wang Haoran was even ranked ahead of his name.

Zhang Aimin is a grateful person. He knows that his current status is inseparable from Wang Haoran’s help and support.

Back then, he was just a small lecturer in the Department of Materials Science and Engineering at Beijing Institute of Technology. He could hardly get any decent scientific research projects and could only help his teacher Fu Zheyuan.

If Wang Haoran hadn't helped him with all his strength, how could he have been promoted to associate professor so quickly, and then become a well-known materials expert in Beijing Institute of Technology and even in the country? How could he have won two national awards?
Now, although he is only an associate professor, his fame and influence are much greater than that of his teacher Fu Zheyuan.

He is now the director of the Department of Materials at Beijing Institute of Technology.

The Department of Materials at Beijing Institute of Technology has become one of the most powerful materials departments in the country, and can even compete with the materials departments at Peking University and Tsinghua University.

Zhang Aimin finished writing the final report and submitted it.

What he didn't know was that once he submitted this report, it immediately caused a stir in many fields.

Because this ultra-strength steel is exactly the material that the country urgently needs!

Zhang Mingxiang, head of the Third Ministry of Machine Building, was one of the first people to see the report on the 406 steel product. After reading the various parameters of the steel, he slammed the table and said, "This super-strength steel is great! Various parameters are much better than our best high-strength steel before. Most importantly, its comprehensive performance in all aspects is excellent!"

Zhang Mingxiang quickly asked someone to contact Shougang, mainly to confirm whether the 406 steel had really reached such a high parameter standard.

Shougang naturally confirmed this.

Afterwards, Zhang Mingxiang called Wang Haoran personally.

On the phone, Zhang Mingxiang said to Wang Haoran: "Comrade Haoran! Before you said that you would equip the troops with the J-10 within two years. At that time, I was a little bit skeptical."

"Because we are lacking a lot of materials!"

"Now, you have developed domestically produced ultra-high-strength steel that is comparable to the strongest special steel in Jusa. You are one step closer to fulfilling your promise."

"Recently, there have been many good news about the J-10. I heard that the fuselage design at the Northwestern Polytechnical University has been basically completed, and you have also solved the biggest bottleneck of the advanced turbofan engine, the single-crystal turbine fan blades. I heard that the avionics system that you personally presided over is almost complete. Is the J-10 about to be released?"

Wang Haoran smiled and said, "Leader, there is still a lot of work to do!"

"There are two other key materials: new aluminum alloy and carbon fiber composite materials. We haven't figured them out yet, but we'll be there soon."

“After all the materials are ready, the next step is the production of parts.”

"My plan is to produce two or three J-3 prototypes in March next year, and then conduct comprehensive flight tests for three to four months and undergo comprehensive inspections by the Air Force. If there are no problems, we will be ready to start mass production. I hope that we can equip the troops with at least 10 J-50s within a year. In this way, our air disadvantage will be alleviated." Because of the gap in the Air Force, to this day, planes from Jing Province still fly over Longguo from time to time to carry out harassment activities. Those noisy things are very arrogant!

Therefore, the shortcomings in the air force must be made up.

In addition to advanced aircraft, advanced missiles must also be produced.

Even if we have advanced fighter jets, if the missiles cannot keep up, we will be like a toothless tiger and no one will be afraid of us.

Zhang Mingxiang felt his blood boiling after hearing this.

He smiled and said: "Aircraft are important equipment for the country, and we must speed up production!"

"We once produced 300 J-6 fighters in just half a year, making a huge contribution to the country's air defense."

The J-6 can be said to be the most produced fighter jet in the Dragon Country.

A total of thousands of them were produced, with the strategy of quantity being the key to success.

It was not a problem in the era of second-generation aircraft, because air combat at that time was close-range dogfighting, a test of courage and wisdom.

What our air force commanders and fighters lack the least is courage and wisdom.

Therefore, the J-6 could shine at that time.

However, by the time of the third generation of aircraft, the J-3 had almost become a target for the enemy.

Because the opponent can lock on to you and kill you from a distance that you can't even see!

In principle, an advanced fighter jet can defeat a hundred enemies alone as long as it has enough bombs!

The quantity is meaningless.

Wang Haoran could tell that what Zhang Mingxiang meant was that producing 50 aircraft a year was a bit too few.

He smiled and said, "Leader, the J-6 can be quickly mass-produced because it has a simple structure and does not have too many functions."

"But fighter jets are different now."

"Our J-10 is a heavy fighter, and it can carry at least five or six tons of ammunition! And because it uses a large number of electronic components and computer control centers, its industrial chain is also longer."

"At the beginning, producing 50 a year would be considered pretty good."

Zhang Mingxiang was surprised: "What? Five or six tons of bombs?"

"Isn't that almost the same as a bomber?"

"The maximum bomb load of our H-6 is only 9 tons..."

"Then, wouldn't the J-10 be much bigger?"

The Dragon Country currently has no heavy fighter jets, so Zhang Mingxiang has no idea about the J-10.

Wang Haoran smiled and said, "Leader, the maximum bomb load of Jusa's F16 is 6.8 tons."

Zhang Mingxiang nodded: "I've seen reports about this. Are you saying that our J-10 can be comparable to the F-16?"

Wang Haoran nodded and said, "In fact, the five or six tons I just mentioned is when the fuel is fully fueled. If the fuel is reduced, then the maximum bomb load of the J-10 I designed will exceed 7 tons!"

"Moreover, our aircraft will surpass the F16 in terms of ceiling, maneuverability, climbing speed, maximum flight speed, radar search distance, etc."

"If we are going to build one, then let's build a heavy fighter that can lead the world!"

"Of course, in order to meet various different uses, we can develop various series of models in the future!"

Zhang Mingxiang was overjoyed.

He grinned and said, "Haha! If this is really possible, the Air Force will be so happy!"

"Our air force is really too backward, haha!"

Wang Haoran said: "As long as our J-10 can be successfully launched, we will not lag behind in the field of advanced fighter jets in the future."

"Of course, I think we have to do one more thing next, which is to quickly develop cruise missiles."

Zhang Mingxiang said: "Then this is a matter related to aerospace."

Aviation and aerospace are separate.

Even later, aerospace was divided into two parts: rocket manufacturing and missile manufacturing.

Wang Haoran smiled and said, "I will talk to Comrade Yongjun about this."

The Dragon Kingdom now has cruise missiles as well as medium- and short-range missiles.

However, most of them are just in their infancy.

It just solves the problem of whether or not there is one, which is not advanced enough.

Zhang Mingxiang said: "It is indeed very important to develop advanced missiles, because killing the enemy and winning the battle is the most important ultimate goal!"

"Comrade Haoran, your achievement will be kept top secret and will not be publicized to the outside world. There won't even be any internal commendations!"

"But all kinds of rewards will be implemented!"

"Also, when the time is right, we will publicize your achievements!"

"I hope you can understand."

Wang Haoran smiled and said, "Leader, my awareness is not that low. In fact, I am ready to remain anonymous for the country."

"I will do whatever the country needs me to do!"

……

Seeing the achievement of 406 ultra-high-strength steel, Shi Yongjun, the head of the 7th Machine Department, could no longer sit still.

Although Wang Haoran has not directly participated in the projects of the 7th Machine Department, the 7th Machine Department has been able to achieve relatively good results in rocket launches in the past two years, which is inseparable from Wang Haoran.

Because the advanced chips and electronic components developed by Wang Haoran have greatly improved and enhanced the rocket's control system, making the rocket's launch, orbit change, and orbit entry smoother and more accurate.

Therefore, Shi Yongjun also admired Wang Haoran very much.

Today, Longguo Aerospace is still using the special steel H58 developed in 31 in rocket manufacturing.

The H31 is actually pretty good.

However, its performance is still relatively poor.

In order to ensure the safety of the rocket, the outer skin of today's rockets is relatively thick.

This also makes the rocket quite bulky and heavy.

Shi Yongjun compared the parameters of H31 and found that most of them were only one-third of 406 or even lower.

He thought, if this was used in rocket manufacturing, it could greatly reduce the thickness of the rocket skin!

That would lighten the rocket's weight.

This allows you to add more fuel and carry more load.

The more Shi Yongjun thought about it, the more excited he became.

He immediately communicated with Zhao Aiguo, the chief engineer of Longguo Aerospace.

After reading the report on the 406 steel, Zhao Aiguo was shocked and said, "If someone else said they had developed such an amazing ultra-high-strength steel, I would definitely think they were bragging."

"But this result was produced by Wang Haoran's team, so I have to believe it."

"Comrade Yongjun, this is a great thing!"

"This indicates that our aerospace industry can reach a higher level!"

Shi Yongjun nodded and said, "I think so too."

"Then let's go visit Comrade Haoran together!"

"I hope he can give more support to the development of our country's aerospace industry."

"After this special steel is produced, our aerospace department must be given priority for use!"

Shi Yongjun and Zhao Aiguo went to see Wang Haoran together.

Wang Haoran naturally would not sit in the office. He was busy in Pangu Company's experimental factory.

He is leading the team to build the aerospace system and is testing and improving it first.

After Shi Yongjun saw Wang Haoran in the test workshop, he smiled and said, "Comrade Haoran! I am very dissatisfied with you!"

"You're being a little biased."

"You were wholeheartedly helping your comrades in the aviation department, but you forgot about us! Haha!"

Wang Haoran invited Shi Yongjun and the other man to sit down in the lounge in the test workshop. He smiled and said, "Leader, your department is full of talented people! You have a very strong talent pool, and you have done a very good job."

"I think if I learn, it's still possible, but I don't dare to teach others."

Now, the pioneers of the two bombs and one satellite are still alive, and they all work in the field of aerospace.
