Start with the aviation industry

Chapter 170 Getting Started with Microsoft Stock and Site Selection
After calming down, Qin Jun really couldn't believe it.

As an insider in the industry, he asked himself that he still had a good understanding of the domestic machine tool industry, and the gap with Western developed countries was even clearer.

If Lin Feng wasn't bragging, then this CNC broaching machine is of a world-class level, and it is only a CNC broaching machine, and it is estimated that there are very few people who can surpass this one.

"Boss Lin, didn't you exaggerate the publicity?"

"No, of course not." Lin Feng said, "Our data is not exaggerated at all. I still have a tape here. Team Leader Qin can take a look."

There is projection equipment in the office, and Lin Feng has already noticed it.

Qin Jun raised his hand to check the time. A few minutes later, he had another meeting. It was a relatively large-scale joint venture machine tool company in the coastal area. Their general manager had an appointment, and he wanted to meet.

This is a bit tangled.

After hesitating for a while, Qin Jun decided to take a look at the contents of the tape. Maybe the literal data may be exaggerated, but the video should be difficult to exaggerate.

He took the tape from Lin Feng and put it into the playback device himself. Soon, the 21-inch color TV in the office began to play the video.

This was shot in the 406 workshop. The broaching is the turbine disk of the turbo shaft eight. The shooting angle is very appropriate and the definition is relatively high.

After looking at two or three thirds, Qin Jun asked, "This broaching is a military product."

Lin Feng said: "The tongue and groove broaching of the turbine disk of the aero-engine is one-time broaching and forming, and the pass rate is 100%."

what!
Broaching turbine disks for aero engines! ! !
He knew that the accuracy of the tenon and groove of the turbine disk of the aero-engine is very high, and the material is also a high-temperature alloy material that is difficult to process. This broaching machine can actually broach such parts.

He was really a little surprised.

It seems that this broaching speed is very fast and the efficiency is also very high!
seeing is believing!

Seeing this with his own eyes in the video, Qin Jun knew that the other party should not be bragging. Judging from the broaching situation, this is also a genuine CNC broaching machine, not a simple CNC broaching machine.

Lin Feng observed the words and expressions.

Noticing that Qin Jun's face seemed to be a little different, Lin Feng took the opportunity to introduce, "We have delivered several broaching machines, which are mainly used in the production and manufacture of military products for military enterprises. Its high precision and high efficiency have won the approval of the users. Unanimous praise."

After hearing Lin Feng's introduction, Qin Jun nodded.

I said in my heart, this is the CNC equipment I was looking for so hard.

that's it!
This year's International Machine Tool Show relies on this CNC broaching machine to support the appearance, so that foreigners can also take a look, we also have world-class CNC equipment.

Thinking of this in his heart, Qin Jun watched the processing video of the CNC broaching machine slightly excitedly, and then watched the introduction video.

There was a knock on the door.

His secretary came in and reminded, "Leader, 10 minutes is up, and Yu Shifei from Shifei International CNC Equipment Group is already waiting."

Qin Jun said impatiently, "Let him wait a little longer."

The secretary glanced at Lin Feng in surprise, and thought in his heart, what's the matter, the leader made an exception when he agreed to only give him 10 minutes.

He had no choice but to back out and tell Yu Shifei to wait.

Qin Jun seemed very interested, "Mr. Lin, your CNC broaching machine is very good. So far, which companies have bought it."

Lin Feng answered patiently.

Next, Qin Jun watched the video and asked a few questions from time to time. After three or four 10 minutes, he was satisfied.

"Mr. Lin, such a CNC broaching machine must be exhibited. We will arrange a booth of type A. If you have any requirements, you can put forward them."

Class A booth!

There are three types of booths in this International Machine Tool Show, among which type A booths have the largest area, the best location and the least number.

The ones who can obtain the category A booths are basically large-scale state-owned machine tool enterprises in China, or well-known foreign machine tool enterprises.

For private companies, it is generally a category C booth.

Lin Feng became happy all of a sudden, and he did not forget to thank him, "Team Leader Qin, thank you for your support, thank you so much."

After giving Qin Jun several colorful introduction materials, Lin Feng and He Hua got up to say goodbye, and Qin Jun politely sent them to the door.

His secretary looked at Lin Feng again in surprise, thinking in his heart, what happened today, the leader made an exception and chatted with them for so long.

"Secretary Zhang, I can go in."

Yu Shifei waited for more than half an hour, and when he saw Lin Feng and the others finally came out, he asked cautiously.

Secretary Zhang said a little bit embarrassed, "I'm afraid I won't be able to do it today. I'll call you tomorrow. The leader has an important meeting and I can't receive you."

Sure enough, Qin Jun's voice came over, "Xiao Zhang, the meeting will start in a few minutes, let's go now."

Lin Feng and He Hua returned to the hotel happily.

"Boss, I didn't expect such a surprising result."

Lin Feng said, "Yeah, I didn't expect that it would be nice to be able to participate in the exhibition, but it actually gave us a category A exhibition area."

"Boss, you don't have to worry about participating in the exhibition. I will make all the preparations. After the exhibition starts, you can just come and take a look."

The two happily returned to the hotel where they stayed. He Hua had already started booking air tickets to go back first. There were still many things at home.

Lin Feng would stay for a few more days, at least until Wu Tianhua came over and the two parties signed a contract on the book "Harry Potter and the Chamber of Secrets".

He Hua, Wei Bing and others went back by plane first, while Lin Feng went to his newly bought house.

I took out the key, opened the door, walked in and looked around, and the more I looked, the more satisfied I was, especially the antique furniture, which seemed to be made of precious wood, either red sandalwood or huanghuali.

Among them is a large carved bed with exquisite workmanship, not only gilded, but also inlaid with precious stones in some places.

After looking around, I returned to the hotel in a good mood.

The next day, morning.

After Lin Feng got up and had breakfast, he was thinking in his heart, where should he go for fun today, should he go to the Forbidden City or climb the Great Wall.

It's a pity that I was alone, if only Xiaoxiao was by my side, Lin Feng thought of Hu Xiaoxiao in his mind.

Feeling that playing alone was less interesting, Lin Feng decided to just watch TV in the room and wait for Wu Tianhua's call by the way.

To pass the time, I even rented a few tapes on the street, all of which are currently popular Hong Kong movies.

Just after reading the first tape in the room, the phone rang, and Wu Tianhua's voice came from the phone as soon as he got through.

"Mr. Lin, we have already got off the plane and have lunch together at noon."

"Mr. Wu, you are so fast."

"Ms. Lin's second book has been written. We can't hurry up. If you sell the copyright of this book to others, then I won't even have time to cry."

I didn't expect Wu Tianhua to speak so funny.

"Mr. Wu, you and I will book a place now."

"No, we'll talk about it when we meet at the hotel."

After finishing the call, Lin Feng thought in his heart, Wu Tianhua's speed is really fast, he came here in only two or three days.

Does my book really have such a big appeal?

Near noon.

Lin Feng simply sat down in the hotel lobby and waited patiently there. Not long after, Wu Tianhua and his party arrived and walked into the hotel lobby.

Lin Feng walked over quickly, "Mr. Wu, I'm so glad to see you again."

The two shook hands happily.

Wu Tianhua said, "Mr. Lin, what I want most now is to take a look at your manuscript."

Lin Feng said, "That's easy. I've brought the manuscript. You'll have plenty of time to read it after dinner."

After chatting for a few words, Wu Tianhua and the others went to check in, but he didn't go upstairs, and the entourage who gave his luggage to him went out talking and laughing with Lin Feng.

They didn't go far, and saw a nice restaurant on the side of the street, the two went in, ordered a few dishes and chatted.

While eating, chatting.

"Ms. Lin, you don't know how popular your book is now. Our phone calls are all buzzing, everyone wants the book."

500 million copies, all sold out in less than two months, which shows how popular it is.

Lin Feng smiled happily, "My second book, how many copies are you going to print for the first time?"

Without even thinking about it, Wu Tianhua broke away, "The first print is 1000 million copies, and it will be released in North America and Europe at the same time. If the number is less, I'm worried that I will be urged by the publisher to ask for the book again."

After speaking, he laughed heartily.

The two of them had a meal, and basically negotiated the contract, which was basically the same as last time, only a little higher, 50 US dollars + 10 points of royalties.

Wu Tianhua didn't mean to bargain, but just jokingly said, "Mr. Lin, the third book comes out, so it can't be any higher."

Lin Feng also agreed, "Probably not. I'm already very satisfied with 10 points of royalties and 50 US dollars in royalties."

After thinking for a while, Lin Feng said again, "After we sign the contract, Mr. Wu will buy all of my 50 US dollars in royalties for Microsoft stocks."

"Oh, Teacher Lin also likes to play stocks."

"I basically don't play stocks, but I am optimistic about Microsoft. The $50 stock is ready to be held for a long time. If you are interested, Mr. Wu can also buy some Microsoft stocks as a long-term investment like me."

Wu Tianhua thought about it for a while, but he didn't say that he also bought Microsoft's stock.

Whether to buy it is his business, anyway, Lin Feng is going to buy 50 US dollars.

That is to say, I don't have enough funds. If I have money, it doesn't matter if I buy millions of dollars in Microsoft stocks.

Microsoft, which was acquired in 1991, will rise to an unimaginable level after ten or even twenty years of long-term investment, which is no less profitable than hoarding houses.

After eating, the two walked back to the hotel and chatted a lot along the way. After returning to the hotel, Lin Feng gave Wu Tianhua his manuscript with confidence.

After getting the manuscript, he didn't leave, just sat on the sofa and read it. As for his two assistants, they were already drawing up the contract.

"Ms. Lin, the writing is wonderful, not inferior to the first one."

After watching it for less than half, Wu Tianhua was full of praise.

He originally wanted to continue reading, but his assistant had already printed out the contract and brought it over in duplicate.

Lin Feng and Wu Tianhua each picked up a copy and looked at it. After reading the contract, Lin Feng first said, "I think the contract is fine, it's just that we just negotiated it."

Wu Tianhua said, "I also think it's okay, then let's sign."

After speaking, he first picked up the pen and signed his name, and then Lin Feng also signed his name.

From now on, the global English and Traditional Chinese publishing rights of the book "Harry Potter and the Chamber of Secrets" will be sold to Wu Tianhua.

Of course Lin Feng is satisfied with this price!
The contract was signed and the manuscript was given to Wu Tianhua. It was no fun to stay in the capital alone. Lin Feng returned by plane that night.

This is the second day after Lin Feng came back from the capital.

Fang Anping was reporting to Lin Feng on the site selection of the test bench.

The design and development of the LH1500 turboshaft engine has been progressing relatively smoothly. Now, of course, the construction of the test bench must be considered.

Because the test run of the aero-engine is quite noisy, Lin Feng does not recommend building the test stand in his own 1500-acre factory area. Instead, he considers choosing a place that is not far away, has convenient transportation, and is less crowded.

Fang Anping reported, "Boss, we have chosen two places, one is here."

He spread out a map of Phoenix City on the table and pointed out these two locations.

From the map, both locations are good, less than ten kilometers away from the factory area, and one is located in the northwest of the factory area, at the foot of Jiucai Ridge.The other one is located in the southwest of the factory area, a place called Zhangshuchong.

Lin Feng looked at the map, waved his hand and said, "Let's go, let's go to the field and make a decision."

Not long after, a jeep set off. The driver of the small car class was driving, Wang Gang, the director of the overall design office, was sitting in the co-pilot, and Lin Feng and Fang Anping were sitting in the back seat.

"Let's go to Chive Ridge first."

The car drove for about 10, [-], [-] minutes to the foot of a mountain. This mountain is called Jiucai Ridge, which is not too high. The terrain at the foot of the mountain is relatively flat and open.

Fang Anping introduced, "I think this place is good. Boss, look at the place. It is backed by a hillside, and the terrain is flat. The straight-line distance from the nearest village is more than 300 meters."

Lin Feng listened to Fang Anping's introduction, looked at the place, and nodded slightly. The place is really good.

But he didn't make a decision right away, Lin Feng waved his hand and said, "Let's go, let's go to Zhangshu Chong to have a look."

Everyone got on the bus one after another, and it took about three or four 10 minutes to arrive at this place called Zhangshuchong.

This is a ravine with mountains on both sides, a valley in the middle, and a clear stream at the lowest point of the valley.

The car could only be parked at the entrance of the valley and could not continue to drive in. Everyone got out of the car and walked in along a mountain road less than one meter wide.

The valley is quiet, the scenery is good, and there are crisp birdsong.

Lin Feng said, "I seem to think this place is better, it's farther away from the residential areas. If you build a test platform here, you don't have to worry about disturbing the residents."

But soon, Lin Feng changed his mind.

Because after walking a few hundred meters inside, I saw a large area of ​​graves, and the secrets were all graves.

Lin Feng smiled and said, "It seems that I have been careless. So many people are buried here. If we build a test bench here, it will disturb the people who sleep here."

Fang Anping said, "This was my mistake, I didn't expect there to be so many grave mounds."

Lin Feng decided, "Then our test platform should be located at the foot of Jiucai Ridge. You decide the specific location, and try to stay away from the village we saw."

Fang Anping said, "Boss, don't worry, we will choose the most suitable location for the test bench."

Phoenix factory, assembly workshop.

Worker Liu Xinfa is carefully weighing each blade. This is a high-temperature alloy precision-cast blade. The blade is hollow and there are rows of neat small holes, which are the cooling holes of the blade.

Turbine blades work at high temperatures. In order to prevent the blades from burning out, it is necessary to cool down the blades.

There are two main measures for cooling. One is air cooling. Air film cooling holes are processed on the blades so that the surface of the blades is covered with a relatively low temperature cooling air film to prevent direct contact between the hot gas and the blades.

Another method is to cover the blade with a layer of coating, and the coating is used to isolate the direct contact between the hot gas and the blade body.

"Old Liu, what kind of blade is this? Why have I never seen it before?"

"Hey, look, the leaves are not only hollow, but also have rows of small holes."

"In addition to the small holes, there seems to be a coating on the surface of the blade."

Several workers in the hot parts assembly class noticed Liu Xinfa's situation, and came over one by one to see what was strange.

Liu Xinfa said, "This is the first-stage turbine blade of the turboshaft engine designed and developed by Leihuo Technology Industry Group."

"I've heard of that engine. Their speed is so fast. The turbine blades are all out, but the number is a little small."

There are more than 100 leaves, which is not too much.

"Their speed is really fast. I heard that at least half of the design drawings have been drawn."

Liu Xinfa weighed each blade, carefully recorded the weight of each blade, and must refer to the blade weight when assembling later.

Installing the turbine blades on the turbine disk is not a casual assembly, but a delicate process. First, weigh the weight of each blade, and then perform static balancing on the turbine disk, and mark the direction and position of the center of gravity of the turbine disk.

When assembling the blades, the blades are selected according to the direction of the center of gravity of the turbine disk. The heavier blades are assembled with the opposite direction of the center of gravity, and then the light and heavy blades are assembled correspondingly. The purpose is to balance the quality as much as possible.

The working speed of the turbine disk is as high as tens of thousands of revolutions. If the mass distribution is slightly uneven, there will be severe vibration, which will be destructive to the engine.

When assembling the blades of the whole disk, try to distribute the mass as evenly as possible, and then do dynamic balance, which requires relatively high requirements. For example, this turbine disk requires a dynamic balance of 5 grams and millimeters.

This turbine disk is used as a design verification. After the assembly is completed, it will be sent to the laboratory of Phoenix Institute for a series of design verification.

Liu Xinfa who was weighing suddenly stopped because he saw Wang Tianfang and Lin Feng walking towards this side.

The two of them were walking towards this side while talking about something.
