Chapter 419: Ready to go to guangcheng

"Permit, I may go to Guangcheng for business in a few days." Gu Ying said that he had dinner with permission at noon.
"I heard that Nantian Group is going to recruit people in Guangcheng?" Nodded with permission. He has just returned recently. This month, he went to inspect the islands around the world. It was really a leader's sentence.
"Correct."
Gu Ying nodded gently. Now she is not the front desk, but she is transferred to the personnel department and becomes the deputy manager of the personnel department. Passable.
This recruitment is not trivial, the scope of recruitment is very large, involving many universities and vocational colleges in Guangcheng.

"The boss's phone, let me answer it first."
Allowed to take out his mobile phone and glanced at it, said quickly, Gu Ying picked it up, and quickly picked it up.
"Good boss, I will arrange this."
After allowing the phone to hang up, he smiled with some joy in his face and looked at Gu Ying's mouth.
"It seems that we can also meet in Guangcheng." With a certain smile, Gu Ying was slightly stunned and instantly thought of something.
"The boss is also going to Guangcheng, why?" Gu Ying was puzzled and roughly guessed.
"I don't know, just let me prepare, and then let me go to Guangcheng together, but we will pass earlier than you and leave tomorrow." Permit shook his head and said.
"Tomorrow?" Gu Ying lowered her head for a moment and nodded gently.
"How long will you stay?"
"I don't know, see what the boss means !!"
Allowed to shake his head. He was completely blinded. He was only notified last night and was completely unprepared.
After Wang Hao informed the permission, he started to prepare some tank data. He had to study some tank data in advance.
"Xiaolong, how much data does the tank have?" Wang Hao looked at the data collected by Dragon Brain, and the data close to 1tb made him look a little stunned.
"Huge Brother, according to your requirements, it is classified according to the category. The information relates to various models and origins of domestic tanks, as well as foreign tank data."
Dragon's metallic voice sounded in Wang Hao's ear.
Wang Hao nodded his head lightly and scanned the data. The 1t data, he would definitely not be able to read it in a short time. He had to spend some time to understand. The information to be understood may not need to be fully understood. It is necessary to understand and analyze some domestic tank data.
As for foreign tank data, he can learn from it without having to study it.
When Wang Hao looked at the materials, the huge amount of data made him seem to have found the state of learning again, and he could not help being addicted to it, and he was very fascinated.
Unconsciously, time passed, the sun was setting, Wang Hao recovered from the data, looked up at the time, and then walked towards Yang Lu.
Walked into the production workshop, above an open space, Yang Lu frowned and looked at an engine in front of him, expressing doubts in his expression.
Wang Hao approached and looked at Yang Lu in contemplation, not disturbing but waiting quietly.
"Boss, when did you come?"
Yang Ling's head immediately saw Wang Hao and couldn't help being surprised.
"I just arrived, what happened, and encountered a problem?" Wang Hao looked at a device in front of Yang Lu with some curiosity, his face showing curiosity.
"Boss, the turbine blades and turbine discs have insufficient high temperature resistance, but I have been thinking for a long time, and I have not found available high temperature resistant materials. The materials currently used seriously affect the life of the engine."
Yang Lu shook his head and said with regret in his eyes.
"Engines made with the current materials have a long lifespan." Wang Hao's face was not unexpected. This was as long as he expected. The biggest problem encountered by jet engines is the high temperature resistance of the materials.
And the most influential are two items, one is the turbine blade and the other is the turbine disk.
Turbine blades generally use high temperature resistant alloys, and use directional crystallization technology to form columnar crystals or single crystals along the longitudinal axis to eliminate the grain boundaries perpendicular to the stress direction.
The growth technology of columnar crystals or single crystals, including crystal orientation deviation control, hollow blade casting technology, is a difficult point of development, the most important of which is high temperature resistant materials.
Turbine disks are different, because the operating temperature is relatively low, and the stress conditions are more severe and complicated, so isotropic polycrystalline materials are required. Therefore, forging high temperature resistant alloy is adopted, forging is used to shape, and the grain is refined, and the finer the grain, the better.
Alloy is difficult to forge, it is very easy to crack in forging, which is a big difficulty. In addition, the strengthening of the grain boundary and the control technology of the low melting point phase are also difficult.
The international development direction is powder metallurgy turbine disks, avoiding the problem of forging and forming, and greatly refining grains. This is a revolutionary technology. Even in advanced countries, it is still far from large-scale practical.
Wang Hao does not have the manufacturing process in this respect, nor does he go deeper to study materials science, and masters the configuration formula of some high temperature resistant materials.
Actually, there is no problem with the processing technology of Wang Hao's vast R & D center, except that it takes time to study high temperature resistant materials.
"The boss, using the current materials to make the engine, without considering other external factors, it is estimated that if the continuous flight is often more than five hours, it may be at risk of scrapping." Yang Lu shook his head regretfully, after his research , He discovered that this does not
It's not as easy as you think.
Research is researched out, but the jet engine represents the display of comprehensive scientific and technological strength. He currently has no problem in manufacturing a jet engine, but encountered a big problem in the practical application of the jet engine.
The engine made by him, after being tested, completely does not meet his requirements. The jet engine of which country continues to run for five hours will be scrapped. Such an engine can only exist in the laboratory and cannot be manufactured. Unless the aircraft has been improved.
"If it doesn't work continuously, how long does the engine need to rest to prolong 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 before it can be used again. Although it has an impact, it should not be too big." Yang Lu hesitated, thinking back to his heart, his previous test, this data, he It really does.
"Then the matter of materials is not considered first. 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 about it and said, he has not Research the idea of ​​materials science.
To start the study of materials, at least let him upgrade the physics to the seventh level. However, although the material science is not studied for the time being, this does not mean that Wang Hao gave up the practical application of the jet engine.
"Ho, you mean." Yang Lu's eyes lit up, and an idea came into his mind.
"Yes, as you think, using multi-jet engine mode, multiple conversions, so that the jet engine can work in rotation, to avoid this high temperature problem, anyway, the aircraft we arrive at is estimated to be unmanned. The Lord, without weapons, will have enough space for the aircraft to use multiple engines and rotate. "
Wang Hao nodded gently and said, he sighed slightly, said with a sigh,
"At present, the R & D center is still too short of manpower. At present, only you and Lanwei are two. You are responsible for the machinery. Lanwei is responsible for the development of software and materials. We are still stagnation. In general, we are now It ’s a serious student. It takes time to improve the overall strength, so you have to be more flexible to think about ways. "
Wang Hao's words made Yang Lu nod. Indeed, at present, there are too few staff in the R & D center, and Yang Lu also knows that the Hao Han R & D center should not be joined by too many people, especially those who do not understand, because of the secrets here It is too much.
The research here is completely beyond Yang Lu's expectations. Now the technological strength of the vast research and development center can be very strong, but as the boss said, they are students with partial subjects. At present, they The R & D center has no people working on materials.
It is also very difficult to purchase jet engine materials, because this kind of material is all under the control of the state. The price is not to be said first, and whether it will be sold is the root problem.
"Understood, after I tested all the other content, I started to reduce the size of the jet engine." Yang Lu nodded gently, which is also no way to do it.
"Don't worry, I'm here to find you. I'm going to follow me to Guangcheng. There is a project that wants you and Lan Wei to be my assistants."
Wang Hao did not forget that he came to Yang Lu for the purpose of preparing to take Yang Lu to Guangcheng to solve the problem of the balance device.
As for why Yang Lu should be taken in the past, because of the application of jet engines, it must be turned into an airplane ~ EbookFREE.me ~ This time with Yang Lu out, it is equivalent to let Yang Lu be proficient in the application of balancing devices in advance. The aircraft can be equipped with device balance.
But this floating balancing device is definitely different from the vehicle balancing device on the ground, and there are many areas for improvement.
"Lanwei, this piece, you inform me, and leave early tomorrow morning."
After Wang Hao finished speaking, he left.
He went to the robot test building and took a look at Zhang Nan.
Wang Hao looked at Zhang Nan in the practice without disturbing, nodded in satisfaction, watched Zhang Nan connected to the five robots, and after the breakthrough, the ball went back and forth in an instant, then instantly turned into lightning, and started again, using the change The rhythm of the clouds is like passing through the sixth robot.
After passing, Zhang Nan watched the last three standing robots move. Without thinking about it, he shot directly.
"Yes."
Zhang Nan jumped up excitedly. It wasn't his shot that came in. He was excited that he finally passed the difficult mode, that is, he had connected six people.
Originally, his shooting was just a matter of luck. The robot that guarded the gate, using the linkage mechanism, the strength of the goal-keeping, is completely a metamorphosis.
Zhang Nan has shot countless times in the middle, but every time the robot has the ability to predict the future, the time the goalkeeper's robot is waiting, he waits early on the only way for football, steady income.
