Chapter 182 Benchmarking World Class

What kind of helicopter is designed and developed?
These days, Lin Feng has also thought about it. Compared with armed helicopters, he is more inclined to design and develop transport helicopters.

why?

Because the requirements for transport helicopters are relatively low, it does not have complex weapon systems, does not require a fire control system, and even bulletproof armor can be simplified.

Let's start with the simple, because Leihuo Technology Industry Group currently lacks the foundation to design and develop helicopters, and the designers are better at aero-engine design.

However, everything is systematic.

Lin Feng is still planning to design and develop this helicopter by relying on the system, designing the general drawing, and preparing to draw some important design drawings by himself.

Then guide the design team by myself, and finally draw all the design drawings. To put it bluntly, except for some high-level designers such as technical supervisors and senior engineers, ordinary designers are tool people.

They are not required to have creative designs, as long as they draw the design drawings according to the instructions.

Before designing the system, Lin Feng still needs to do some preparatory work. At least he needs to investigate and understand what kind of general-purpose helicopters the military needs.

First understand the requirements and needs of users, and then start specific design work based on these.

Lin Feng had read some professional books on transport helicopters, and at this moment, information on transport helicopters also appeared in his mind.

What is a transport helicopter.

It refers to the helicopter used to transport and carry materials. In the military, it can not only carry and transport soldiers, but also perform airborne assaults on the battlefield, transport wounded soldiers and transport supplies, and can also transport military equipment, such as artillery and military equipment. vehicles etc.

Compared with transport vehicles, the most important thing about transport helicopters is that they are not restricted by terrain and can carry out vertical replenishment. They are an indispensable mobile force in modern warfare.

The largest transport helicopter in the world is the Mi-26 helicopter manufactured by the former Soviet Union. It is also the heaviest helicopter in the world, with a maximum load of 20 tons and a maximum take-off weight of 56 tons, which is equivalent to the take-off weight of the American C-130 Hercules transport aircraft.

The most famous transport helicopters are Black Hawk, Chinook and so on.

The output power of a single LH1500 turboshaft engine is 1526 kilowatts. Such a good turboshaft engine cannot be overkill. Lin Feng is going to design and develop a heavy transport aircraft.

Each helicopter has two LH1500 turboshaft engines with an output power of 3052 kilowatts.

This is only the output power of the prototype. This turboshaft engine will definitely be improved and modified in the future. It should not be a big problem for a single unit to reach 1800+ kilowatts.

Medium Transport Helicopter!
Lin Feng had a clear positioning in his mind for this helicopter, which has not yet been designed and developed.

After imagining this medium-sized transport helicopter in the future, Lin Feng got up and left the office, drove to Phoenix Factory, knocked on the door and walked into Zhong Zimin's office.

"President Lin, you are back."

"I came back yesterday."

Zhong Zimin got up to greet him, and made two cups of hot tea by himself. The two sat down on the sofa, chatting and drinking tea.

He seemed to have guessed the purpose of Lin Feng's visit, and said proactively, "I have already reported your plan to design and develop helicopters by yourself. The higher-ups have explained to you that you will try boldly and give full support."

Hearing this, Lin Feng felt relieved.

The meaning of these eight words is very clear, it is to let Leihuo Technology and Industry Group try boldly, don't be afraid and worry, and the military will give full support when encountering any difficulties.

"Mr. Zhong, with these eight words, my heart is much more stable."

Zhong Zimin smiled, "The above attitude is very clear, Mr. Lin, when will you start the design and development of this helicopter?"

It can be seen that he hopes that Leihuo Technology Industrial Group will start the design and development work as soon as possible, and he hopes to see this helicopter take a test flight earlier, and even enter the army.

Lin Feng also smiled and reminded, "Mr. Zhong, it's still very early, and there are still many things to do before the design."

"First of all, I need to understand the military's requirements for this transport helicopter."

"In addition, I also want to learn about the most famous transport helicopters in the world today."

Zhong Zimin said, "It's still early, so how long will we have to wait?"

"It won't be too long, because I hope the first transport helicopter prototypes will be built before our engines go into low-volume production."

So fast!

The first prototype can be built before the engine goes into low-volume production!

He was a little bit disappointed just now, but all of a sudden, the disappointment in Zhong Zimin's heart was swept away, and all that was left was surprise.

He even rubbed his hands excitedly, "Mr. Lin, the speed is really so fast."

"It should be similar, but we need a large number of design and development personnel, especially a group of experienced designers."

Zhong Zimin nodded approvingly, "I will respond to your request."

Then, Zhong Zimin asked curiously, "Boss Lin, do you have any ideas about this helicopter?"

"There are some preliminary ideas."

"First of all, it is a medium-sized transport helicopter, and its transport capacity is higher than that of the American Black Hawk, whether it is transport capacity, carrying capacity, or range, etc."

Zhong Zimin was stunned, thinking he heard it wrong.

Oh my God!

He didn't even dare to think about surpassing the Black Hawk helicopter of the United States. He thought that he would be extremely surprised if he had a quasi-first-class level in the world.

No, even the world's second-class transport helicopters are fine. The military has been longing for medium-sized transport helicopters for a long time.

The newly developed WZ-[-], which has not been successfully developed for a few years, is just a small one among medium-sized helicopters, and its performance is not very good. It is simply incomparable with advanced medium-sized transport helicopters.

Lin Feng said affirmatively, "We will target world-class and surpass world-class."

The two chatted for at least an hour while drinking tea.

After Lin Feng left, Zhong Zimin immediately picked up the phone and reported the situation to his superiors in detail.

…………

406 Workshop.

Wang Qiang unloaded the parts processed on the CNC five-axis, and all the parts of this batch of turbo-axis eight were processed.

Next, he will machine a new part, the reducer casing of the LH1500 turboshaft engine.

There are two pieces in total, placed next to them.

A worker walked by and looked at the two receivers curiously, "Wang Qiang, what kind of parts are these, I have never seen them before."

Wang Qiang said, "Of course you haven't seen it before. This is a part of Leihuo Technology Industrial Group."

"Looks like a reducer case."

"Yes, they are reducer casings."

"Has their turboshaft engine started manufacturing the reducer?"

"It should be used for design verification."

While talking, Wang Qiang cleaned the workbench of the machine tool and began to prepare for the processing of the two reducer casings.

These two receivers are indeed used for design verification.

However, it is not a single-piece verification, but the entire gear unit unit is verified.

This turboshaft engine has a total of five units, and the reducer unit is the only unit design verification.

After some preparations, Wang Qiang installed the right half of the reducer casing on the workbench of the machine tool, ready for processing.

The content of this process is mainly the processing of mounting holes and precision positioning holes. There are no inclined holes with angles, and the processing difficulty is greatly reduced.

As expected of the system design, it does not engage in those bells and whistles at all. It is unpretentious and has excellent comprehensive performance.

The things were installed and everything was ready, but Wang Qiang didn't start processing right away. He was waiting and checking the time from time to time.

This is the first!

According to the requirements of process discipline, the first CNC machining of a new product must have a process technician present throughout the whole process from the beginning to the end of the process.

This is also the rule established by Lin Feng when he was in the 406 workshop. This rule has been maintained until now and has become a craft discipline.

"Brother Wang, I'm late, and I've got something delayed."

Yang Wenjie walked over quickly, with an apologetic expression on his face.

He is now the chief craftsman of Leihuo Technology Industrial Group, mainly responsible for the CNC machining of various parts of the LH1500 turboshaft engine.

Wang Qiang said, "You came here in person, just send the craft technicians below to follow the first piece."

"Brother Wang, you don't know that the reducer casing is the last part in all design verifications, and even our boss is paying attention."

"It's already the last one, your speed is really fast."

Wang Qiang personally processed many parts of this turboshaft engine for design verification, such as axial flow impeller, centrifugal impeller, etc. He did not expect that the design verification would come to an end within a few months.

It's not that he doesn't understand anything, he probably knows that the design and testing of parts will take at least two or three years, or even three or five years.

What about Leihuo Technology Industry Group?
It only takes a few months, no wonder Wang Qiang has a look of surprise on his face.

The two were chatting, but the parts hadn't been processed yet, and sure enough, Lin Feng came over in person, accompanied by Wang Tianfang.

The two walked over directly.

Lin Feng looked at the reducer casing on the machine tool and asked, "The preparations before processing have been done."

"It's ready!"

"Then start processing."

The machine tool starts to process the parts, the drill bit rotates at high speed, drills in easily, one installation hole after another completes the rough machining, followed by the finishing of each hole.

As for Wang Tianfang, he picked up the craft drawing on the table and looked at it.

After looking at it, Wang Tianfang said, "The processing is not very difficult. Except for a few precision positioning holes that require higher precision, the other holes are basically not difficult to process."

It's kind of unbelievable!
But it is!
It is not the first time that Wang Tianfang has discovered such a situation. Since some parts of this turboshaft engine began to be processed, he often went to the production site to have a look.

No matter what kind of parts they are, their processing difficulty is only average compared to similar turboshaft engine parts, and the difficulty is not great.

Wang Tianfang once guessed that the processing difficulty of this turboshaft engine of Leihuo Technology Industrial Group is estimated to be basically the same as that of the turboshaft eight engine.

incredible!

If you don't see it with your own eyes, who would believe it!
This turboshaft engine is a world-class turboshaft engine, with a single output power of 1526 kilowatts, a power-to-weight ratio of 5.6, and a service life of 3000 hours during the first turnaround.

"Mr. Lin, your design is excellent. While ensuring the excellent performance of the engine, you also fully considered the craftsmanship of each part."

"How did you do it?"

Lin Feng smiled, but did not answer directly, because the design comes from the system.

Produced by the system, it must be a boutique!
"Mr. Wang, I also think the design is excellent. I am personally very satisfied. After the reducer casing is processed, all the parts that we need to verify the design are manufactured."

At this moment, Lin Feng himself is looking forward to it. The design verification has been completed, and all the design drawings will be drawn before the National Day.

After the National Day, the parts of the first verification machine will start to be manufactured. It is hoped that in about half a year, at most one year, the first verification machine will be manufactured, and then the verification test will start.

Lin Feng is not worried about whether the verification test will pass in one go. There is no problem in manufacturing the parts. As long as they fully meet the design requirements, they will probably pass the verification test in one go.

The two watched the processing of the first reducer casing next to this CNC five-axis machine, and saw the processing inspection results.

All processing dimensions are completely acceptable, and there is no problem with the position of each hole.

Wang Tianfang invited, "Boss Lin, come and sit in my office."

Lin Feng readily agreed, "Okay, I'm just tired from standing, so I'd like to sit with you and have a cup of tea."

Lin Feng thought in his heart, Mr. Wang took the initiative to invite me over, probably because he wanted to talk to me about this turboshaft engine.

The two walked and talked all the way, entered the factory office building of the Phoenix Factory, and entered Wang Tianfang's office one after the other.

"I happen to have some good tea here, so let's drink it."

Wang Tianfang made two cups of tea with his own hands, and then sat down on the sofa with Lin Feng.

"Mr. Lin, I heard that you are planning to design and develop a military transport helicopter. Is there such a thing?"

Lin Feng was slightly taken aback.

Originally thought that he would chat with himself about this turboshaft engine?
Where did he think, he cut straight to the point and asked directly about the military transport helicopter that was about to hold a design study.

Lin Feng nodded and said, "There is indeed such a plan, Mr. Wang, you are really well informed."

Wang Tianfang said, "Can you tell me what kind of military transport helicopter you will design and develop?"

"Don't worry, I will keep it a secret, and I won't reveal a word to anyone, it's just out of curiosity."

Lin Feng believed in Wang Tianfang, knowing that he would not gossip around, so it didn't matter if he had a proper chat with him about this transport helicopter.

"The design is still being conceived, and the military has not given me any special requirements."

"But I think, our turboshaft engine is so good, the helicopter that matches it can't be too bad, I plan to benchmark the world-class, and strive to surpass the world-class, so that this helicopter can become the best military transport helicopter in the world one."

Lin Feng exuded a strong self-confidence all over his body!

What about Wang Tianfang?

Surprised on his face, he came back to his senses and said, "If the design and development of this transport helicopter is successful, then the gap between us and Western countries in the field of transport helicopters will be narrowed at once."

"Boss Lin, you really dare to think and do it!"

Lin Feng said, "No matter what, we have to give it a try."

"Preparing to design and develop such an advanced transport helicopter should also face many difficulties."

"Yes, there must be difficulties. One is the pressure of funds, and the other is talents."

It is enough to burn money to build this turboshaft engine, and it will burn even more money to build a transport helicopter. Lin Feng is really worried that his funds will not be able to keep up.

Design and R&D requires a large number of tool people. It is not enough to have only tool people. At least a group of truly qualified professionals is also required.

Wang Tianfang said, "I may not be able to help you with the design and development of this transport helicopter, but I can recommend someone to you."

"I have an alumnus who majored in the design and manufacture of aircraft. He has been engaged in the design and development of transport aircraft. Now he is mainly engaged in the design and development of helicopters. He is a professor-level senior designer..."

Wang Tianfang introduced the situation of his alumnus.

Lin Feng listened carefully, and said in his heart, isn't this the professional design talent I dream of.

If there are several such professional design talents, plus a large number of tool people, then there will be no big problem with this transport helicopter.

"Mr. Wang, we just need such a talent. Help me connect."

Wuyou was relieved, and agreed immediately, "No problem, I'll contact you for you, I think he is very willing to come over."

After sitting here for about half an hour, Lin Feng got up to say goodbye.

His time is also very precious now, he has a lot of things on hand, after leaving the Phoenix factory, he will go directly to Hexi.

What about Wang Tianfang?

He politely sent Lin Feng to the door of the office, and after watching Lin Feng leave, he immediately picked up the phone on the desk.

Old man, Leihuo Technology Industrial Group will be a brand new world for you. I believe that after you join, you will definitely do a great job.

Wang Tianfang is [-]% optimistic about Leihuo Technology Industrial Group. If it is not really impossible to jump over, he would like to work with Lin Feng in the past.

He picked up the phone and dialed a number...

…………

Lin Feng returned to Hexi, but he didn't go to his office immediately, and drove to the factory area under construction.

It has been more than eight months since the construction of the first phase of the project, and earth-shaking changes have taken place here.

In the forecourt area of ​​the factory, the two buildings on the left and the right have been built to a height of more than [-] floors. The roof will be capped in one or two months, and then decoration will start. It is estimated that they will be put into use around New Year's Day.

The factory gate has been constructed in the first step, and the gold-plated characters of "Leihuo Technology Industrial Group" are very eye-catching.

Lin Feng didn't stop the car, nor did he intend to get out of the car. He just slowed down the car and drove towards the gate of the factory while taking a few glances at the factory area under construction.

Construction is progressing well!

Basically, there is a small change in three or five days, and a big change in ten days and a half months.

The jeep drove to the gate, Lin Feng honked the horn, a security guard ran over, saluted Lin Feng's car, and then quickly opened the telescopic gate.

Lin Feng drove directly into the factory area. Not long after, his eyes lit up!
