Black Technology Research and Development Center

Permit, I may go to Guangcheng for a business trip in a few days. Gu Ying said with permission to eat with him at noon.

I heard that Nantian Group is planning to go to Guangcheng to recruit people? Xue Xie nodded. He also just came back recently. During this month, he went to inspect islands all over the world. It was a word from the leader, and he broke his legs.

right.

Gu Ying nodded gently. She is not the front desk now, but has been transferred to the personnel department and has become the deputy manager of the personnel department. As the personnel department manager, it is naturally impossible to go to Guangcheng to coordinate this part of the interview, so naturally she get over.

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

The boss's call, I'll answer it first.

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

Okay boss, I'll make arrangements here.

After Xu Xing hung up the phone, he looked at Gu Ying with a smile on his face.

It seems that we can also meet in Guangcheng. Xu Xue's somewhat awkward smile made Gu Ying stunned, thinking of something in an instant.

The boss is also going to Guangcheng, why? Gu Ying wondered 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 lightly.

How many days are you staying?

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

Permit shook his head, and his eyes were completely smeared. He also received the notice last night, and he was completely unprepared.

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

Xiaolong, how much data does the tank have? Wang Hao looked at the data collected by Longnao. The data was close to 1tb, which made him a little stunned.

Brother Hao, according to your requirements, it has been classified according to the category. The information involves various types and origins of domestic tanks, as well as foreign tank data.

The metallic voice of dragon's head rang in Wang Hao's ear.

Wang Hao nodded lightly and glanced at the information. He would definitely not be able to read the 1t information in a short period of time. He had to spend some time to understand it. It is necessary to understand and analyze some domestic tank data.

As for foreign tank information, he can learn from it, and he doesn't need to study it.

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

Unconsciously, time passed and the sun went down, Wang Hao recovered from the data, looked up at the time, and walked towards Yang Lu.

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

Wang Hao approached and looked at Yang Lu in deep thought without disturbing him.

Instead, wait quietly.

Boss, when did you come?

Yang Ling looked up and saw Wang Hao immediately, and couldn't help being taken aback.

Just arrived, what's the matter, encountered a problem? Wang Hao looked at a device in front of Yang Lu with some curiosity, and his face showed curiosity.

Boss, the high temperature resistance of turbine blades and turbine discs is insufficient, but I have been thinking about it for a long time and have not found any available high temperature materials. 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 is the service life of an engine made of current materials? Wang Hao had no surprises on his face. This was already within his expectation. The biggest problem encountered by jet engines is nothing more than the high temperature resistance of the material.

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

Turbine blades generally use high-temperature alloys, and use 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 difficulty in development, and the most important one is high temperature resistant materials.

The turbine disk is different. Due to the relatively low operating temperature, the stress conditions are more severe and complex, so isotropic polycrystalline materials are required. Therefore, forged high-temperature alloys are used, forging is used, and the grains are refined. The finer the grains, the better.

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

The international development direction is powder metallurgy turbine disk, which avoids the problem of forging and greatly refines the grains. This is a revolutionary technology. Even in advanced countries, it is still very early to be practical on a large scale.

Wang Hao does not have the manufacturing process in this area, nor does he study materials science in depth, and has mastered the configuration formulas of some high-temperature resistant materials.

In fact, there is no problem with the processing technology of Wang Hao's vast R\u0026D center, except that it takes time to research high temperature resistant materials.

Boss, the engine is manufactured with the current materials. If other external factors are not considered, it is estimated that if the continuous flight time exceeds five hours, it may be in danger of being scrapped. Yang Lu shook his head regretfully. After his research , he discovered that

It's not as easy as I thought.

The research is done, but the jet engine represents the demonstration of comprehensive scientific and technological strength. He currently has no problem in making a jet engine, but he has encountered a big problem in the practical application of the jet engine.

The engine he made did not meet his requirements at all after the test. The jet engine of any country will be scrapped if it continues to run for five hours. An engine like this can only exist in the laboratory and cannot be manufactured. Formed aircraft, unless modified.

If it doesn't work continuously, how long does it take for the engine to rest to prolong its life? Wang Hao leaned 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 back to his own previous test, this data, he There really is.

Then don't consider the issue of materials first. You 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, he has not recently Research ideas for materials science.

To start the research on materials, at least let him raise the physics to the seventh level. However, although materials science is not studied for the time being, this 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 just as you think, using a multi-jet engine mode, multiple units are switched for use, so that the jet engines can work in rotation and avoid this problem of high temperature resistance. Anyway, the aircraft we will arrive is estimated to be unmanned. Lord, without carrying weapons, the space in the plane will be enough for us to use multiple engines and use them in rotation.

Wang Hao nodded lightly and said, with a slight pause in his tone, he sighed and said,

At present, the R\u0026D center is still too short of manpower. At present, there are only you and Lanwei. You are in charge of the machinery, Lanwei is responsible for the software, but the research and development of materials, we are still stagnant. In layman's terms, we are now It is a student who is seriously partial to subjects, it takes time to improve the overall strength, so you have to think of ways to be flexible.

Wang Hao's words made Yang Lu nodded. Indeed, at present, there are too few personnel in the R\u0026D center, and Yang Lu also knows that it is not suitable for too many people to join the Haohan R\u0026D Center, especially those who don't know it, because the secret here is It's just too much.

The research here is completely beyond Yang Lu's expectations. Now the scientific and technological strength of the Haohan R\u0026D Center can be very strong, but as the boss said, they are students of partial subjects. R\u0026D center does not have people who study the material.

It is also very difficult to purchase the materials of jet engines, because these materials are all materials under the control of the state, and the price is expensive, and whether they will be sold or not is the root problem.

Understood, I only started to reduce the size of the jet engine after testing other content. Yang Lu nodded lightly, this is also a way out of nowhere.

Don't worry, I'm here to find you for something. 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 Yang Lu was to take Yang Lu to Guangcheng to solve the problem of the balance device.

As for why they should take Yang Lu there, because if the jet engine is used, it will definitely become an airplane. Taking Yang Lu out this time is equivalent to letting Yang Lu familiarize himself with the application of the balancing device in advance, so that the aircraft can be equipped with a balancing device.

However, this floating balancing device is definitely different from the vehicle balancing device on the ground, and there are many areas that need to be improved.

Lan Wei, please let me know about this one. We will leave early tomorrow morning.

After Wang Hao finished speaking, he left.

He went to the Robot Test Building and Zhang Nan to take a look.

Wang Hao looked at Zhang Nan during practice without disturbing him. He nodded with satisfaction. After watching Zhang Nan connect five robots, the moment after the breakthrough, he took the ball back, turned it into lightning in an instant, started again, and took advantage of the changes The rhythm was like flowing clouds and water, and the sixth robot passed.

After Zhang Nan passed by, he watched the last three robots that were standing still move, without thinking about it, he shot directly.

Yes.

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

Originally, this shot of his was just a chance. That robot that guarded the goal, using the linkage mechanism, and the strength of goalkeeping, was completely abnormal.

In the middle, Zhang Nan shot countless times, but every time the robot seemed to have the ability to predict the future. When he shot, the goalkeeper robot waited early on the only way for football to earn a steady income.
