Black Technology R&D Center

Chapter 419 Prepare to go to Guangcheng
"Xu Xu, I may go to Guangcheng for a business trip in a few days." Gu Ying said after having lunch with Xu Xu.

"I heard that Nantian Group is planning to go to Guangcheng to recruit people?" Xu Xu nodded. He also just came back recently. In the past month, he went to visit islands all over the world. It was really a word from the leader.

"Correct."

Gu Ying nodded lightly. She is not the front desk now, but has been transferred to the HR department and became the deputy manager of the HR department. As the HR manager, it is naturally impossible to go to Guangzhou to coordinate this part of the interview, so naturally she have to pass.

The recruitment this time is not a trivial matter. The scope of the recruitment is very large, involving many universities and vocational colleges in Guangcheng.

"I'll answer the boss's call first."

Xu Xu took out his mobile phone and glanced at it, and said quickly, Gu Ying picked it up, and quickly picked it up.

"Okay. Boss, I'll make arrangements now."

After Xu Xu hung up the phone, with some joy on his face, he looked at Gu Ying and couldn't help smiling.

"It seems that we can also meet in Guangcheng." Gu Ying was slightly taken aback by Xu Xu's frightened smile, and suddenly thought of something.

"The boss is going to Guangcheng too, why?" Gu Ying was puzzled for a while, and roughly guessed it.

"I don't know, just let me prepare, and then let me go to Guangcheng together, but we will go there earlier than you, and we will leave tomorrow." Xu Xu shook his head and said.

"Tomorrow?" Gu Ying lowered her head and thought for a while, then nodded slightly.

"How many days will you stay?"

"I don't know, let's see what the boss means!!"

Xu Xu shook his head, his eyes were completely darkened, and he was notified only last night, so he was completely defenseless.

After Wang Hao notified the permission, he began to prepare some tank data. He wanted to study some tank data in advance.

"Xiaolong, there are so many tank data?" Wang Hao looked at the data collected by the borneol, which was close to 1TB of data, which made him a little dazed.

"Brother Hao, according to your request, we have classified them according to categories. The information involves various models and origins of domestic tanks, as well as foreign tank data."

The metallic voice of the borneol rang in Wang Hao's ears.

Wang Hao nodded lightly, and scanned the information. He would definitely not be able to finish reading the 1T information in a short time. It is necessary to understand and analyze some domestic tank data.

As for foreign tank information, he can use it for reference instead of researching it.

When Wang Hao read the materials, the massive amount of materials made him seem to have found the state of learning again, and he couldn't help but indulge in it, and was very fascinated by it.

Unknowingly, time passed and the sun was setting. Wang Hao recovered from the information, looked up at the time, and then walked towards where Yang Lu was.

Walking into the production workshop, on an open space, Yang Lu looked at an engine in front of him frowning, with doubts in his expression.

Wang Hao approached, looked at Yang Lu who was in deep thought, and waited quietly without disturbing him.

"Boss, when did you come?"

Yang Lingtai turned his head and saw Wang Hao immediately, and couldn't help being surprised.

"Just arrived, what's the matter, encountered a problem?" Wang Hao looked at a device in front of Yang Lu curiously, with a curious look on his face.

"Boss, the turbine blades and turbine discs are not capable of high temperature resistance, but I have thought about it for a long time, but I have not found a usable high temperature resistant material. The materials currently used seriously affect the service life of the engine."

Yang Lu shook his head and said with some regret in his eyes.

"How long will the service life of the engine made with the current materials be?" Wang Hao didn't have any surprises on his face. This was already in his expectation. The biggest problem encountered by jet engines is nothing more than the material's high temperature resistance.

The biggest impact is two items, one is the turbine blade and the other is the turbine disk.

Turbine blades generally use high-temperature resistant alloys, and adopt directional crystallization technology to form columnar crystals or single crystals along the longitudinal axis to eliminate grain boundaries perpendicular to the stress direction.

The growth technology of columnar crystal or single crystal, including crystal orientation deviation control and hollow blade casting technology, is a difficult point in development, and the most important one is high temperature resistant material.

Turbine discs are different, because the operating temperature is relatively low, and the stress conditions are more severe and complex, so isotropic polycrystalline materials are required.Therefore, forged high-temperature resistant alloys are used, formed by forging, and the grains are refined. The finer the grains, the better.

It is recognized that alloy is difficult to forge, and it is very easy to crack during forging, which is a major difficulty.In addition, the strengthening of grain boundaries and the control technology of low melting point phases are also difficult points.

The international development direction is powder metallurgy turbine disk, which avoids the problem of forging and greatly refines the grain size. This is a revolutionary technology. Even in advanced countries, it is still far from large-scale practical use.

Wang Hao has no manufacturing technology in this area, nor has he studied material science in depth, and has mastered some configuration formulas for high-temperature resistant materials.

In fact, there is no problem with the processing technology of Wang Hao's Haohan R&D Center, the only thing is that it takes time to research high-temperature resistant materials.

"Boss, if the engine is made with the current materials, if you don't consider other external factors, it is estimated that if you fly continuously for more than five hours, you may face the danger of being scrapped." Yang Lu shook his head regretfully. , he discovered that this was not as easy as he imagined.

The research has been done, but the jet engine represents the display of comprehensive scientific and technological strength. He has no problem manufacturing a jet engine at present, but he has encountered a big problem in the actual application of the jet engine.

The engine made by him, after being tested, does not meet his requirements at all. The jet engine of any country will be scrapped if it continues to run for five hours. Such an engine can only exist in the laboratory and cannot be manufactured Formed aircraft, unless modified.

"If it doesn't work continuously, how long does the engine need to rest to prolong its life?" Wang Hao came over and looked at Yang Lu's test data seriously.

"It is estimated that after three hours of use, it will take four hours to enable it again. Although this has an impact, the impact should not be too great." Yang Lu was stunned, thinking about it in his mind, his previous test, this data, he There really are.

"Then don't consider the issue of materials. You should first test the stability of the jet engine. If conditions permit, try to reduce the size of the jet engine." Wang Hao thought for a while and said, recently he has no Study the idea of ​​materials science.

To start the research on materials, at least he has to upgrade the physics to the seventh level. However, although materials science is not studied for the time being, it does not mean that Wang Hao has given up the practical application of jet engines.

"Brother Hao, what do you mean?" Yang Lu's eyes lit up, and an idea came to his mind.

"That's right, it's exactly what you think, using the multi-jet engine mode, and switching between multiple jet engines, so that the jet engines can work in rotation to avoid the problem of high temperature resistance. Anyway, the plane we will arrive at that time is probably based on unmanned pilots. Lord, without any weapons, the plane will have enough space for us to use multiple engines and use them in rotation."

Wang Hao nodded lightly, and said, he paused slightly, sighed and said,

"At present, the R&D center is still too short of manpower. At present, there are only you and Lanwei. You are in charge of the machinery, and Lanwei is in charge of the software. However, we are still stagnant in the research and development of materials. In layman's terms, we are now It takes time to improve the overall strength, so you have to be more flexible and think of ways."

Wang Hao’s words made Yang Lu nod. Indeed, at present, there are too few personnel in the R&D center, and Yang Lu also knows that Haohan’s R&D center should not be joined by too many people, especially those who don’t know, because the secret here is It's just too much.

The research here is completely beyond Yang Lu's expectations. Now Haohan R&D Center's scientific and technological strength can be very strong, but it is just like what the boss said, they are students who are partial to the subject. The R&D center does not have people who research materials.

It is also very difficult to purchase the materials for jet engines, because these materials are all under the control of the state. Let alone the high price, the root problem is whether they will be sold.

"Understood, I started to shrink the size of the jet engine after I finished testing other content." Yang Lu nodded lightly, this is the only way out.

"Don't worry, I'm here to find you on business. I'm going to follow me to Guangcheng. There is a project that requires you and Lan Wei to be my assistants."

Wang Hao did not forget that the purpose of coming to find Yang Lu was to take Yang Lu to Guangcheng to solve the problem of the balance device.

As for why Yang Lu was brought there, because if the jet engine is applied, it will definitely become an airplane. Taking Yang Lu out this time is equivalent to letting Yang Lu get acquainted with the application of the balancing device in advance, and then the aircraft can be equipped with a balancing device.

But this kind of floating balance device is definitely different from the vehicle balance device on the ground, and there are many areas that need to be improved.

"Lan Wei, please let me know about this area, we will leave early tomorrow morning."

After Wang Hao finished speaking, he left.

He went to the robot testing building and asked Zhang Nan to take a look.

Wang Hao looked at Zhang Nan who was practicing without disturbing him, and nodded in satisfaction. He watched Zhang Nan pass the five robots in a row, and at the moment after the breakthrough, he caught the ball back, and then it turned into lightning in an instant, and started again. The rhythm is smooth and flowing, passing the sixth robot.

After Zhang Nan passed by, he watched the three robots standing still at the end move, and without thinking about it, he just shot the goal.

"Yes."

Zhang Nan jumped up excitedly. It wasn't that his shot went in. What he was excited about was that he had finally passed the hard mode, that is, passed six players in a row.

Originally, his shot was just a chance. The goalkeeper robot used the linkage mechanism, and its goalkeeping strength was completely abnormal.

In the middle, Zhang Nan shot countless times, but each time the robot seemed to have the ability to predict the future. When he shot, the goalkeeper robot was waiting early on the only way for football, and it was firmly in his hands.
