Chapter 191 Verification Machine Begins Manufacturing

Lin Feng waited while drinking tea in the reception room, chatting with Zhong Zimin from time to time.

"Mr. Lin, the call has already been made, we can just wait here, and I will help you solve the land matter today."

"Okay, let's just wait."

Only a while later, Zhong Zimin received the notice and called the management committee of the park directly. He had to leave immediately to attend an emergency meeting in the provincial capital.

"Boss Lin, then I can't accompany you, I'll take a step first."

"Mr. Zhong, after you return to Phoenix Factory, I will personally come to the door and tell you the outcome of the matter."

"Okay, bye."

Zhong Zimin left in a hurry, and Lin Feng continued to wait patiently by himself.

About two or three 10 minutes later, a person who looked like a leader brought several people to the management committee of the park. He was accompanied by a deputy director of the management committee of the park. As for the director Wu Guangming, he was still there directing people to draw lime lines Woolen cloth.

"You have been waiting for a long time."

As soon as the leader entered the reception room, he showed a full apology. After a few chats, the two sides introduced each other, and then he waved his hand and said, "Then let's go and have a look, Mr. Lin wants that place, we will give you this place."

This is a leader in the province with great power, which also shows that the entire Jiangnan Province attaches great importance to this matter.

Led by the deputy director of the park, a group of vehicles quickly arrived at the side of the 1000-mu land.

After everyone got out of the car, they soon saw Wu Guangming, Duan Xinlian and others.

At this time, they have basically finished everything. A very obvious lime line has been drawn on the soil, and wooden piles have been driven in, and a 500-acre piece of land has been delimited.

When Wu Guangming saw so many people coming, he thought that some of the deputy directors below had brought the investors over for a field trip, but he trotted over quickly.

"Leader, why are you here in person?"

The leader waved his hand and said, "This is Mr. Lin of Leihuo Technology Industrial Group. Mr. Lin and I came here to choose a place. The park will set aside 3000 mu of land for free for Leihuo Technology Industrial Group to build a factory."

what!
Wu Guangming really wanted to say, why didn't I know such a big thing.

But he didn't dare, the leader's rank was much higher than him, and what he said would definitely be what he said, so he could only follow the execution.

The big leader didn't care about Wu Guangming anymore, but pointed to this piece of land that had been leveled and had an area of ​​at least one thousand and several hundred acres.

"Boss Lin, what do you think of this place?"

Definitely happy with this place.

Therefore, Lin Feng nodded and said, "This place is not bad. It is close to the main road in the factory area. Then use this main road as the boundary. I want all the land here."

Wu Guangming would like to remind, this is not possible, there are already 500 mu of land ready for Mr. Duan to build a chemical plant.

But he still didn't dare, so he could only look at Duan Xinlian with pity, and said in his heart, Boss Duan, you don't have this piece of land anymore, even if you draw a lime line, it's useless.

The leader said, "Director Wu, how big is the land that has been leveled?"

Wu Guangming replied, "A total of more than 300 mu."

Lin Feng said, "Our demand is [-] mu. First use the [-] mu to build a helicopter manufacturing plant, and give us the remaining [-] mu within half a year."

More than 300 mu, the area is not too small, enough for the first phase of the project.

On the basis of this land, a processing plant for helicopter parts and a helicopter assembly plant can be built.

And the huge assembly plant, Lin Feng plans to build two in the future, first to build a final assembly plant for transporting helicopters, and another for special armed helicopters.

In addition to transport helicopters, Leihuo Technology Industrial Group will definitely have special armed helicopters in the future.

And it's still a heavy armed helicopter, the kind with ferocious firepower.

As for medium-sized armed helicopters, Lin Feng has no plans to design and develop them for the time being, because Wuzhi Shihui will come out in a few years, and there is no need for him to develop medium-sized special-purpose armed helicopters.

In the future, we will engage in world-class heavy-duty armed helicopters.

Lin Feng looked here for a long time. Not only did he successfully acquire this piece of land of more than 300 mu, but there will be another area of ​​about [-] mu in the future.

Wu Guangming really wanted to say that it would be a bit difficult to deliver [-] mu within half a year, but seeing that the leader and Lin Feng had a happy conversation, he didn't dare to say a word, so he could only do everything possible to ensure the delivery .

Now that the land for the factory building is available, Lin Feng has one less major concern.

After returning to Phoenix City, Lin Feng made a special trip to Zhong Zimin's place, told him the result of the incident, and expressed his thanks again.

Lin Feng also reported the application for special funds to Zhong Zimin.

Time to enter September.

The construction of the first phase of the Hexi plant of Leihuo Technology Industry Group has entered the final stage, and the construction of four plants including the final assembly plant of the aero-engine has been completed.

The construction of the two mechanical processing workshops is the fastest. Now most of the equipment has been installed and debugged, and the processing and manufacturing of the LH1500 turboshaft engine can be carried out.

In the No. 1 mechanical processing workshop, there are two sets of CNC equipment that are very eye-catching. They are imported high-precision CNC five-axis. It took a lot of effort and trouble to import them from abroad.

One or twenty years later, this kind of CNC five-axis is nothing, and it is relatively easy to import from abroad, but in 20, this was restricted by Western countries for export, and there were not many units in the whole country.

The two mechanical processing plants are basically close to the start-up conditions, and it may not be too long before they can be engaged in the production of various parts.

The final assembly plant is also in decent shape. Although the central air-conditioning system is temporarily lacking, other installations such as water and electricity are basically nearing completion.

The two buildings in the forecourt area of ​​the factory are now even more beautiful.

Their glass exterior walls have been installed, which is very classy and often attracts the attention of many people.

Anyone who passes by the main road outside the factory will often look at them, and some people even stop to watch.

"These two buildings are really tall, with at least thirty floors."

"It's so beautiful. It is estimated that such a building can only be found in developed coastal cities."

"I watched them being built. The speed of Leihuo Technology Industrial Group is really fast."

The first phase of the Hexi plant is nearing completion, and the design of the LH1500 turboshaft engine has been fully completed.

All design drawings are archived.

Lin Feng personally went to Leihuo Aviation Engine Design Institute.

Fang Anping, the deputy chief engineer of the model, reported to Lin Fenghui, "Boss, all the drawings have been drawn, and the next step is the internal review, and then the manufacture of the first verification machine."

Only internal review is carried out, and there is no need to invite outside experts or the military to come to review.

The reason is very simple. Lin Feng has confidence in the design of this turboshaft engine, and he knows that even if there is a series of reviews, there will be no problem. Since there are no problems, then simply keep it simple and only conduct an internal review.

Within two days, the internal review began.

The protagonists were of course Lin Feng, Fang Anping and others. Everyone focused on reviewing some of the more important blueprints, and there were hundreds of them in a day.

Basically no major problems were found.

Just a few minor issues that don't matter.

After reading these multiple design drawings, Lin Feng became more confident about this engine, because each of its design drawings is basically consistent with the design drawings provided by the system.

There may be some deviations in some drawings, but they have been corrected by Lin Feng during the drawing process.

The internal design review was successfully passed.

The next step is to manufacture the parts of the first verification machine.

The preparation of the feeding work started two months ago, and the parts for each batch ranged from eight parts, or ten parts, to as many as a dozen parts.

Generally speaking, for the production of the first verification machine, there are only two or three parts for each batch, and no more than three or four parts.

why.

Because it is risky!
The verification machine only verifies the design results, and there is a high probability that there is a problem. After the problem is found, it must be analyzed, the design drawing should be changed, and then the parts will be produced, and then the second verification machine will be used.

Until the verification of the whole machine is passed, if the parts fed at one time are too large, it is likely that they should be scrapped due to changes in the design drawings.

But this problem does not exist in Leihuo Technology Industrial Group, and the feed is at least eight or ten.

Phoenix factory, forging workshop.

The workshop was as busy as ever, and the forging sound of "boom, boom, boom" was deafening. Basically every piece of equipment was working, forging turboprop six, turboshaft eight and other parts.

But there is a pneumatic hammer that is not forging the parts of these engines, but the first and second stage turbine disks of the LH1500 turboshaft engine.

These two turbine disks are made of GH4133 high-temperature alloy, and their shapes are somewhat similar, but the size is different, and the second-stage turbine disk is slightly smaller.

A red-hot bar was clamped by the worker with pliers and placed on the working table of the air hammer. The operator clamped it with long tongs, and then stepped on the pedal with his right foot. The air hammer was bang and bang. Start forging.

It was originally a long cylindrical bar with a length of about 100 meters. Under the hammering of the air hammer, it gradually became a round cake.

This workpiece also became brighter as it was forged, almost becoming a white burnt color.

A worker next to him cooperated and quickly swept away the oxide skin that fell on the workbench. The two workers cooperated very well.

It should be almost there.

The worker operating the air hammer stopped forging and hammering, and the other worker who cooperated with him immediately took a measuring tool and quickly measured the outer diameter of the workpiece.

"It's still 10 meters away!"

"Bang, bang, bang!"

After a few more hammers, the workpiece was even more white-burned, and it was measured again, and the size met the technical requirements.

Another worker immediately took the mold and put it on the workbench, and put the white-seared round cake into the mold.

It was free forging just now, and after reaching a certain size, put it into the prepared mold, and now start die forging.

The blank of the turbine disk of the LH1500 turboshaft engine is a die forging, after a few hammers of "bang, bang, bang".

perfect!

The shape of the workpiece is very beautiful, it fills the entire mold, and the size fully meets the requirements. This hot workpiece is withdrawn from the mold and placed aside.

The first turbine disk blank forging is completed.

Each of these turbine disk blanks is forged into eight pieces, whether it is the first-stage turbine disk or the second turbine disk, there are always eight pieces.

Because the parts are not too big, forging is also quite convenient, a total of sixteen pieces of blanks were forged in less than half a day.

The two forging workers could finally take a breather.

"Finally finished!"

"Old Chen, this is the part of the first test machine of the LH1500 turboshaft engine. It's really strange. Why did Leihuo Technology and Industry Group put in so many materials and forge eight pieces at once."

"Who knows, maybe it's a preparation for future low-volume manufacturing."

"Ah, just start preparing for small batch production. Don't they worry about any problems with the verification of the whole machine?"

Some parts blanks are forged in the forging workshop, and some parts are cast in the precision casting workshop of Phoenix Factory, such as reducer casings, compressor casings, etc., and even the precision casting of turbine impellers.

Hexi factory area, No. 1 factory building.

There are already some workers in the huge factory building, and a small number of machine tools have also started to process the parts of the first verification machine.

One of the CNC five-axis is preparing for processing, and the other is already processing the axial flow impeller of the verification machine.

Through the glass door, you can see the processing situation more clearly.

The speed of the alloy milling cutter is fast, and it is milling the blades of the axial flow impeller. The "C"-shaped metal chips generated splash on the worktable, and are rushed into the chip collection tank by the coolant, and are slowly sent to the machine tool through the conveyor belt. In the metal shavings collection bucket next to it.

Yang Wenjie took a technician by his side and watched the machining of the axial flow impeller with his own eyes.

The NC program was compiled by him under the guidance of the technician, basically referring to the idea of ​​the axial flow impeller compiled by Lin Feng back then.

"master!"

Yang Wenjie suddenly called out, and Lin Feng was walking over accompanied by Qin Jianguo, general manager of Leihuo Aero Engine Company.

When he was in the 406 workshop, Yang Wenjie had learned CNC programming from Lin Feng for a period of time, and he always called Lin Feng his master.

This is easy to understand, such thick thighs must be hugged tightly.

Lin Feng did not treat him badly either. Yang Wenjie is now the deputy technical director of Leihuohangfa's No. [-] machining workshop.

If he continues to work in workshop 406, it would be nice to be the leader of a technical team, but here he is going up like a rocket.

Leihuo Aero Engine Company currently has two machining workshops.

The first workshop is mainly responsible for the processing of large discs, small discs and axial flow parts.

The second workshop is mainly responsible for the processing and manufacturing of casings, blades, nozzles, and some other small parts.

Lin Feng walked to the front of this CNC five-axis machine, looked at the iron filings in the metal scrap collection bucket, nodded and said, "It's all C-shaped metal scraps, it seems that the processing is good."

Yang Wenjiehui reported, "The processing is normal, and in a few hours, the first axial flow impeller will be processed."

Lin Feng nodded, and left after looking here for a few minutes. He looked around every machine tool that processed parts.

Now there are more than [-] parts with drawing numbers that have started to be processed one after another, and in ten days and a half months, more drawing numbers will be processed.

in the office.

Lin Feng was looking at the planning and design drawing of the helicopter factory.

The first phase of the project covers more than 300 mu of land, such a large area requires professional planning and design.

The first draft of the planning and design drawing has been sent to Lin Feng's desk.

It can be seen from this planning map that there is an office building in this factory area, and several helicopter parts manufacturing and processing factories, each with an area of ​​more than [-] square meters.

Of course, the largest area is the helicopter assembly plant.

It is 180 meters long, 120 meters wide, and covers an area of ​​21600 square meters. There is no problem in completing the final assembly of two or three hundred helicopters every year, and at least three helicopter final assembly production lines can be launched at the same time.

After carefully looking at it, he felt that there was basically no problem, and it was completely in line with his own intentions. Lin Feng took a pencil and wrote a few words on the first draft of the planning and design.

"Agreed to the plan."

After Lin Feng signed the agreement, it is estimated that it will not be long before the formal design plan will be drawn up, and then the construction of the helicopter manufacturing plant will begin.

Free land is fragrant!
Lin Feng no longer has to worry about the land for the construction of the factory.

The total area is 3000 mu. In addition to the helicopter manufacturing plant, assembly plant, and office building of the factory, there will also be a supporting helicopter airport.

The area of ​​the airport is nearly 2000 mu, which can be used for helicopter test flight, parking, take-off and landing in the future.

Lin Feng even thought, after the construction of the airport is completed, a row of transport helicopters will be neatly parked on the tarmac in the future, how spectacular and enjoyable it will be!
Not even transport helicopters.

After this transport helicopter enters mass production and is officially installed, Lin Feng is also planning to design and develop heavy-duty armed helicopters.

At that time, the long row of heavy armed helicopters will also stop.

While thinking about these things, the phone ringing on the desk interrupted his thoughts, he hurried over, picked up the phone and said loudly, "Hello, I'm Lin Feng."

Zhong Zimin's joyful voice came from the phone, "Boss Lin, I want to tell you some good news."

Suddenly, Lin Feng's heart moved slightly.

"Mr. Zhong, has it been approved by the higher authorities?"

Zhong Zimin said, "Mr. Lin, you are really good at predicting things. It has indeed been approved, a total of 4500 million."

Oh my God!

It was actually 4500 million!
When Lin Feng first filed the application report, he thought that if the above can approve two or 3000 million, he would be very satisfied, because our country is not rich, and there are too many places to spend money, so we should not be able to give ourselves too much money.

It was so much more than I expected.

Lin Feng was pleasantly surprised in an instant.

"Mr. Zhong, this money is like a timely gift. With it, our helicopter factory can start construction immediately."

Zhong Zimin said, "Start construction as soon as possible, and manufacture the first transport helicopter as soon as possible. The higher-ups are paying attention to this transport helicopter."

"Don't worry, we will manufacture the helicopter as soon as possible."

After finishing the call, Lin Feng walked up and down the office excitedly, and said several times in his mouth.

Nice!
