Start with the aviation industry

Chapter 165
Lin Feng took the empty seat next to He Hua.

He Hua guessed that he was too engrossed in reading, and while reading seriously, he kept writing with a pen, not noticing that there was another person beside him at all.

However, several students noticed Lin Feng.

Someone gave him a look, which seemed to say, classmate, you are so awesome, that is Professor He, dare to sit beside him.

Lin Feng smiled slightly at the classmate, then looked at He Hua, coughed lightly, finally, He Hua noticed something, and he looked over.

Lin Feng seized the opportunity and said softly, "Professor He, hello."

He Hua was slightly taken aback, "Which department are you from? I don't seem to have seen you before, so I don't have the slightest impression."

Lin Feng took out a business card of his own and gave it to He Hua, and said, "I am not a student of Jiangnan University, I came here just because of the reputation, and I came here specifically to find Professor He."

This is of course a white lie, in fact Lin Feng just met He Hua by chance.

He Hua took a look at the business card, slightly surprised, "You are really the boss of Leihuo Technology Industrial Group."

He works in machinery, so he is aware of some relatively big movements in the manufacturing industry. Leihuo Technology Co., Ltd. was established with a registered capital of 5000 million and a factory area of ​​1500 mu. He Hua has heard about this company several times in provincial newspapers. group.

Lin Feng said, "If it's fake, I'm indeed the boss of Leihuo Technology Group. This is not a place to talk. Let's find a place to drink something and sit down and talk. How about it?"

He Hua only hesitated for a moment, then agreed.

He is suffering from the fact that no one invests. A big boss like Lin Feng is indeed the person he wants to make friends with.

Not long after, the two left the library. There was a teahouse not far from the school gate. Lin Feng ordered a pot of good tea and some snacks, and sat down to chat with He Hua.

First of all, Lin Feng introduced his Leihuo Technology Group, and also talked about the future development direction. Aeroengine design, development and manufacturing are the main business, but he is also planning to develop various equipment manufacturing. The current products already include CNC broaching machines.

After introducing his situation, Lin Feng asked with concern, "Professor He, I heard that you are planning to start a business and enter the manufacturing industry."

He Hua did not hide anything, nodded and admitted, "I do have such a plan. I have a few products that I think are good. I want to manufacture them, but I have not been able to do so because of lack of funds."

Lin Feng threw out an olive branch, "Professor He, our Leihuo Technology Industry Group needs talents like you. As long as you are willing to come, I can let you serve as the deputy general manager of Leihuo Technology Industry Group. The annual salary starts at 30 yuan, and there is also a bonus at the end of the year."

1991 in 30, that is a proper high salary, and there is also a bonus at the end of the year.

He Hua was a little tempted, but felt that it might be better to be his own boss, so he said, "Mr. Lin, I plan to set up a construction machinery manufacturing company. You only need to contribute 500 million yuan for the start-up capital, and I can give you [-]% of the shares." .”

Of course, Lin Feng would not let him do it alone, "Professor He, you don't need to start your own business. Our Leihuo Technology Group is your best development platform. The products you design and develop can also be manufactured and brought to the market."

After some lobbying, He Hua finally agreed.

In addition to serving as the vice president of Leihuo Technology Industry Group, he also asked to take charge of the equipment branch under Leihuo Technology Industry Group.

He is going to manufacture the newly designed cement mixer through this company and put it on the market.

Of course, Lin Feng agreed immediately, and promised that the group would pay patent fees for the products designed and developed by He Hua and the others, so that they would not suffer any disadvantages.

"Professor He, welcome to join us."

"Thank you Mr. Lin for your appreciation. I'll finish the school's affairs as soon as possible, and then report to the group."

"It's okay, come back after you take care of it."

The big hands of the two were tightly held together, Lin Feng was a little excited inside, but it didn't show on his face.

This is the joining of capable generals.

With a legendary figure like He Hua, the development of Leihuo Technology Industrial Group will be smoother and smoother. This is not only a talent who understands technology, but also management ability is one in a million.

Back at the hotel, Lin Feng took a long time to fall asleep.

There is no way, I am so happy in my heart, I never thought that I would have such an unexpected harvest when I came to Jiangnan University.

The next day.

Lin Feng said goodbye to Lin Lan, promised to come and see her next time he was free, then drove away from Jiangnan University and returned to the office of the equipment branch factory.

The work of the design office is progressing step by step. There is a design technical outline written by myself and these drawings drawn by myself. Everyone can carry out specific design on the basis of these things.

In addition, Fang Anping has come over to serve as the deputy chief designer of the model, helping to manage the design, and everything is much easier.

What Lin Feng had to do was to go there every now and then to take a look at the blueprints designed by everyone, or to guide everyone in the design work.

"Boss, Mr. Zhong's representative came yesterday afternoon. I told him that you went to the provincial capital. He went back a little disappointed."

After listening to Wang Yalong's report, Lin Feng said, "Is there anything he said?"

"That's not true." Wang Yalong said.

Lin Feng thought in his heart that he would go to the Temple of Three Treasures for nothing. As the representative of the general army of the Phoenix Factory, Zhong Zimin would definitely not take the initiative to come here if there was nothing important to do.

Could it be for the LH1500 turboshaft engine.

Very likely.

The design of this engine is progressing smoothly, and some important and key parts have begun to be manufactured at the Phoenix Plant, and then undergo design verification tests. These cannot be hidden from the military representatives.

This is wow!

There is nothing more gratifying than the fact that the military is paying attention to this turboshaft engine. Lin Feng even felt a little excited in his heart. In order to confirm his guess, he picked up the phone on his desk and called.

"Hi Mr. Zhong, I'm Lin Feng."

"Boss Lin, you're back from the provincial capital."

"Just came back, the people below reported that you have been here, what's the matter?"

Zhong Zimin said, "There is indeed something to do, I will come here now."

After a while, Zhong Zimin really came over and shook hands with Lin Feng as soon as he came in. He didn't put on airs at all, just like a friend with many faces.

This turboshaft engine is awesome!

Zhong Zimin felt that no matter how much he lowered his status, it was not too much.

The two shook hands warmly and were polite, then sat down on the sofa and chatted, and soon got straight to the point.

Zhong Zimin said with admiration, "Mr. Lin, you are amazing. I heard that you are designing and developing a turboshaft engine with excellent performance."

Sure enough, it came for this turboshaft engine.

Lin Feng was secretly happy.

"Mr. Zhong, our turboshaft engine is in the process of design and development. We have completed the general design drawings of the five units and most of the key and important parts."

Lin Feng introduced the progress of the design and development in more detail. Zhong Zimin listened carefully, without interrupting Lin Feng's introduction throughout.

After Lin Feng finished speaking, Zhong Zimin said, "I heard that your axial flow impeller has performed a design verification test at the Phoenix Institute, and the performance is very good. Mr. Lin, can you give me a detailed introduction to the performance and design features of this engine? ?”

"of course can!"

Lin Feng agreed immediately, and then introduced in detail.

Zhong Zimin also listened carefully the whole time, took out a pen, opened his notebook and recorded carefully.

At this moment, his heart is agitated!

It is really a 1500-kilowatt turboshaft engine with world-class comprehensive performance, which is comparable to the American T-700 turboshaft engine.

He quickly controlled his inner excitement, tried to calm himself down, and asked further, "Boss Lin, when will the verification machine be released?"

After the general design is completed, after a series of component design verifications, the manufacture of the first complete engine will begin.

This is the verification machine.

The main function of the verification machine is to conduct a test run to verify whether the performance of the whole machine meets the requirements of the design technical outline.

If the verification is passed, there will be a prototype, and then a 300-hour long test, design finalization, small batch production, etc.

Lin Feng pondered for a while, and answered conservatively, "According to the current situation, we are sure to produce the verification machine within two years."

what!
Just two years!

Zhong Zimin thought it would take at least three or five years, but it only took two short years. He seriously suspected that he had heard wrong.

"Boss Lin, you said it only takes two years."

Lin Feng murmured in his heart, I said that I have been very conservative for two years, but even so, I almost scared Mr. Zhong.

"Yes, we are sure to get the verification machine out within two years."

Really two years!

Zhong Zimin could no longer control his excitement. This surprise was too great. He stood up with a slightly excited expression on his face, and walked back and forth in the office twice.

This is his personal habit.

When encountering difficult things, or encountering exciting things, he will walk around like this.

After walking back and forth for two times, Zhong Zimin stopped, "Boss Lin, we need such a turboshaft engine, you must get it out as soon as possible, if you need our help, just come and find me."

This is wow!

With the support of the military, Lin Feng felt that the pressure on his body was much less, and he quickly thanked, "Thank you, Mr. Zhong. At present, we are mainly engaged in the production and manufacturing of parts and design verification tests. Our factory area is still under construction. Among them, these matters may require the cooperation of Phoenix Factory and Phoenix Institute."

Zhong Zimin agreed without hesitation, and waved his hand, "There is no problem with these, I will personally greet these two units."

After learning about the LH1500 turboshaft engine in detail, Zhong Zimin went back happily.

The first thing he did when he returned to the office was to pick up the phone and report the situation to his superior in detail.

The superior asked twice on the phone whether the situation was true. After verifying the situation, he instructed to pay attention and report regularly.

Perhaps, higher levels of the military will pay attention to the Leihuo Technology Industrial Group, and even more to the turboshaft engine that is being designed and developed.

He Hua came to report and began to take office.

For this reason, Lin Feng personally held a high-level meeting and announced the appointment of He Hua, who will be the deputy general manager of Leihuo Technology Industry Group.

So far, Leihuo Technology Industrial Group finally has two vice presidents. Wang Yalong is mainly responsible for the construction of the new factory area, and He Hua is responsible for the daily management of the group and concurrently serves as the general manager of the equipment branch.

The framework of the group was basically set up, and it seemed inappropriate to work in the offices of the equipment branch factory. Lin Feng told the management committee of the park his request, and the other party immediately gave him a three-story office building.

This is a newly built office building, which has been renovated and has not yet been put into use. It belongs to the management committee of the park and is now temporarily used by Leihuo Technology Company.

So, there was a small move, and some management and technical personnel moved into this office building.

For example, the human resources department, finance department, legal department, group office, etc. have all moved here and are no longer in the equipment branch factory.

In the equipment branch factory, only some management personnel and some technical personnel are left to serve the production and manufacture of CNC broaching machines.

Because of work needs, Lin Feng approved to buy two small cars, one is a military green jeep, the other is a car, and three three-wheeled motorcycles.

After He Hua took office, he went to the manufacturing site of the equipment branch factory the next day and saw the third CNC broaching machine being assembled.

The first CNC broaching machine was delivered to Phoenix Factory last year, the second CNC broaching machine was also delivered, and the third CNC broaching machine entered the final assembly, and it is estimated that it will be delivered in about a week.

After seeing this CNC broaching machine, He Hua was full of praise. When he learned that this CNC broaching machine was designed and developed by a group of technicians led by Lin Feng, he learned another side of Lin Feng.

It turns out that the boss is also so skilled in technology, it is really unbelievable.

It has been two days since I joined Leihuo Technology Group. As I got to know him better, He Hua felt more and more that joining this team should be the wisest choice in his life.

in the office.

Wang Tianfang is receiving a guest from afar. This is his college classmate and one of his best friends, Xu Xingwen, the technical deputy director of a large military industrial enterprise.

This military industrial enterprise is mainly engaged in the power manufacturing of surface ships, and they are imitating a high-power gas turbine for ships.

The tenons of the blades of this gas turbine and the tenon and groove of the turbine disk must be broached, and the precision requirements are relatively high. No, he came here specifically to ask Wang Tianfang for help.

"Old classmate, I'll leave it to you this time."

"We should help each other. If you feel that you owe me a favor, then next time I go to your factory, you can open a bottle of good wine."

"Okay, deal!"

The two laughed happily.

After laughing, Wang Tianfang suggested, "Since you are planning to imitate gas turbines, there may be more than one gas turbine in the future. I suggest you buy a CNC broaching machine. The CNC broaching machine of Leihuo Technology Industrial Group is good. It is not only high in efficiency, but also accurate. Also high."

"Old classmate, 300 million units, we still have to think about it."

Seeing the other party's answer, Wang Tianfang didn't continue to persuade, he got up and said, "Let's go, let's go to the manufacturing site, and the broaching of your large turbine disks must have started."

These parts had already been delivered to the broaching site, and had been placed next to the CNC broaching machine for several days. Xu Xingwen and the others just came over yesterday, so they only started pulling the test materials yesterday afternoon.

To Xu Xingwen's delight, the sample passed broaching at one time. No, after preparations, the first part began to be broached this morning.

Manufacturing site.

Lin Weidong and his apprentices are basically ready for broaching, and the first official part is also installed on the working table of the broaching machine.

"Master, this part is really big, with a diameter of 560, the largest turbine disk I have ever seen."

Lin Weidong nodded and said, "Fortunately, the maximum diameter is only 560. If it exceeds 600, our broaching machine will not be able to do it."

The CNC broaching machine also has size requirements for the broached parts. This broaching machine requires the outer diameter of the part to be 50 to 600. If the maximum outer diameter of the part is less than 50 or greater than 600, it cannot broach.

"Master, it seems that Mr. Wang and the others are here."

Lin Weidong looked over quickly, not only saw Wang Tianfang, but also Xu Xingwen who came yesterday, Yan Bing, Jiang Haitao and others followed behind them.

At least a few meters away, Yan Bing asked loudly, "Squad Leader Lin, how are you getting ready?"

Lin Weidong quickly replied, "Leader, you are ready, and you are about to start the broaching of the first official part."

Wang Tianfang nodded slightly, and said personally, "Then start broaching."

Mr. Wang personally spoke, and Lin Weidong immediately pressed the start button of the broaching machine, and the broaching machine began to work under the control of the numerical control program.

With a sound of "咻", the long knife box moved quickly on the guide rail, the worktable also tilted to the specified angle, and the broach began to broach the parts.

For such a large turbine disk, the size of the tenon and groove is also relatively large, and each tenon and groove needs to remove more metal, which requires more broaches.

The total length of these broaches is more than ten meters in length. It is absolutely impossible for an ordinary broaching machine to hold so many broaches at one time.

This CNC broaching machine can.

There are two broach slots on the long knife box, each of which can hold a broach, and the total length of the two broach slots exceeds 15 meters.

Now the broach of the last row of broach grooves is broaching the part. About 1 minute, the rough broaching of the first tongue and groove is completed. Under the control of the NC program, the turbine disk on the worktable rotates at an angle. The broach broaches the second tenon and groove.

So fast!
This efficiency is simply unbelievable.

Xu Xingwen saw that within a few minutes, the broaching was completed with several tongues and grooves, which felt a little unreal.

The broaching speed is really fast and the efficiency is extremely high. After the first row of broaches finishes broaching, the second row of broaches starts broaching. This is fine broaching. After broaching by this row of broaches, the tenon and groove are completely formed .

About an hour and a half.

The tongue and groove are all broached!

Xu Xingwen thought in his heart, the efficiency is so high, the broaching was completed in an hour and a half. I don't know how the broaching quality is, whether every tenon and groove is qualified.
