Start with the aviation industry

Chapter 310
As soon as the call was made, Luo Pingfan's voice came over, and he got straight to the point.

"Mr. Lin, when is it convenient for you, I want to come over and disturb you again."

As soon as Lin Feng heard this, he knew that it was probably a visit to ask himself about the development of a certain missile. After thinking about it for a while, Lin Feng replied, "I've been at the company for a few days, and you can come over anytime."

"Really, that's great." Luo Pingfan was pleasantly surprised, "Mr. Lin, to be honest, I undertook the task of designing and developing an air-launched missile. The user's positioning is at the world's advanced level, and it has strong general performance , can be launched on multiple air platforms in the future."

Lin Feng said, "We are also planning to design and develop such a missile. In addition, we are also planning to design and develop air-to-air missiles, precision-guided bombs, etc. After you come over, we will have a chat."

Luo Pingfan is overjoyed!
"Mr. Lin, we will book a ticket right away, and we will arrive at your company tomorrow morning."

After chatting for a few words, the two hung up the phone. Lin Feng opened some design drawings drawn in his computer. After looking at them for a while, he selected some and printed them out for preparation for tomorrow.

These drawings include design drawings of air-to-air missiles, precision-guided bombs, and air-to-surface missiles. These weapons are all designed systematically. Lin Feng just selected a part of the design drawings in his mind and drew them.

Luo Pingfan's speed was very fast, and a group of five people walked into Leihuo Technology Industrial Group at around ten o'clock the next morning, and the two parties sat together and communicated easily and happily.

First, Luo Pingfan introduced Lin Feng to the other four people who came with him, including a missile design expert.

"Mr. Lin, this is Sun Xiang, a newly hired expert in our research institute. He graduated from Stanford University with a doctor degree in aerodynamics. He is only 37 years old this year."

Immediately, Lin Feng took another look at Sun Xiang.

This is a great man!

A doctorate from a world-class prestigious university is definitely a scarce resource in China. Luo Pingfan and the others are so lucky to have acquired such an outstanding talent. To be honest, Lin Feng is a little jealous.

The Leihuo Weapons Branch Company is being established. In the future, it will be engaged in the research and development of various missiles, precision-guided bombs and other weapons. It just needs a large number of excellent talents. It would be great if there is someone like Sun Xiang.

A returnee doctor from a prestigious school should have been aloof, but Sun Xiang didn't. He looked very humble, and took two steps forward to shake hands with Lin Feng, "Boss Lin, hello, I'm Sun Xiang."

Lin Feng said with satisfaction, "Expert Sun is a returnee. Such outstanding talents are very scarce in our country."

"Boss Lin, I'm just an ordinary person." Sun Xiang said humbly.

Luo Pingfan introduced other people, and they came forward to shake hands with Lin Feng one by one, and then everyone sat down on the sofa and started to get down to business.

"Mr. Lin, to be honest, we are under a lot of pressure this time, and the user's requirements for this missile are too high."

He introduced the user's requirements for this missile again.

Then, Luo Ping said, "President Lin, you are an expert in missile design, can you give us some advice and guidance?"

Lin Feng said, "We are also developing an air-to-ground missile, which will be used on this stealth strategic bomber in the future. It may not be suitable for light fighters, but you can refer to some technologies of this missile."

The all-weather third-generation light fighter has a take-off weight of only about ten tons. It is indeed not suitable for air-to-ground missiles that are too large in size and weight. Such missiles should be used by heavy fighters or bombers.

The main purpose of light fighters is air combat, mainly carrying combat missiles, short-range or medium-range air-to-air missiles, and sometimes air-to-ground missiles to strike ground targets.

However, such air-to-ground missiles are relatively small in size and weight, that is, on the order of several hundred kilograms, and very few of them exceed 500 kilograms, while the air-to-ground missiles carried by bombers often weigh more than 1000 kilograms.

It is of course good to have a reference, it is much better than having black eyes.

Luo Pingfan said, "Boss Lin, I hope you can tell us about the air-to-ground missile designed and developed by your company."

Lin Feng was not stingy at all, and first spread out the general design drawing of the prepared missile on the big table, and everyone gathered around.

"This is an air-to-surface missile designed and developed by us that can be launched from a bomber to strike ground targets as well as sea targets."

Looking at the shape of the missile, Luo Ping said in surprise, "Mr. Lin, this is a hypersonic missile."

"Yes, this is a hypersonic missile." Lin Feng said, "It has a streamlined shape and a two-stage engine. After being accelerated by the second-stage engine, the speed can reach up to 10 times the speed of sound, and it can strike 500 kilometers away. ground targets."

Oh my God!

10 times the speed of sound!
What kind of concept is this? Luo Pingfan and others are very clear. Ordinary missiles are two or three times the speed of sound.

Lin Feng didn't care about everyone's reaction, and continued to introduce, "In addition to the characteristics of supersonic speed, it also has stealth performance, which is difficult to be captured by radar."

what!
Still invisible!
If it can't even be caught by radar, it is almost impossible to be intercepted. Luo Pingfan is an expert in this field. He deeply knows that such a missile cannot be intercepted by any country with the current technical level.

Too awesome!

Luo Pingfan had seen big scenes before, but his heart was still agitated. He quickly took several deep breaths, tried to calm himself down, and continued to listen to Lin Feng's introduction of this missile.

In addition to hypersonic speed and excellent stealth performance, it also has extremely high precision, because its guidance method is very advanced, which is what Luo Pingfan wants to learn and understand.

It is estimated that the missile they will design in the future will not be able to achieve a hypersonic speed of 10 times the speed of sound, nor will it be able to achieve stealth performance, but in terms of guidance and strike accuracy, the design of this missile can be used for reference.

So, after listening to Lin Feng's general introduction to this missile, Luo Pingfan and others began to focus on asking about some key technologies of this missile in terms of precision guidance.

Facing Luo Pingfan's modest inquiry, Lin Feng did not rush to answer for the time being, but said jokingly with a smile, "President Luo, this is a key technology that is hard to buy, and it is also the world's top precision missile guidance technology. What is going to be exchanged, or to compensate us for something."

Luo Pingfan was taken aback.

Then he thought in his heart, what Mr. Lin said was not unreasonable, such advanced technology must not be shared with himself for free, so what is the exchange?

After thinking about it for a while, Luo Pingfan said, "President Lin, why don't you make an offer, we can talk about the price."

Hearing this, Lin Feng smiled happily, "There is no need to talk about the price, I can provide you with this key technology for free, but your Missile Research Institute has a lot of talents, just give us a group of professionals, the number does not need to be too many, two. 30 people will do."

In Lin Feng's eyes, Luo Pingfan's missile research institute is a big dog.

Because it is a national military industry unit, dozens of hundreds of college students are allocated every year, and most of them are graduates from famous domestic schools. In addition, the Missile Design Institute has been established for 30 to [-] years. After so many years of accumulation, there are really many expert-level students. talent.

Luo Pingfan was taken aback.

It never occurred to him that Lin Feng didn't want money, but people, but he couldn't tell whether it was true or not.

"Boss Lin, you are telling the truth."

Lin Feng glanced at Sun Xiang and the others. These people are actually pretty good. It would be great if they could join the Leihuo Weapons branch.

"of course it's true."

Luo Pingfan was slightly taken aback again, and then said, "Well, it's not impossible, but we need to go back to a meeting to study before we can decide."

Lin Feng waved his hand and said, "Okay, then let's talk about this precision guidance technology first."

After speaking, Lin Feng took out another design drawing and spread it out on the big table. This is the general design drawing of the missile's guidance part seeker. Combining this drawing, he began to introduce the precision guidance technology of this missile to everyone.

Lin Feng described the design structure, design principles, etc. in great detail.

Luo Pingfan and the others seemed to have opened a new door, and felt like they had entered a whole new world. It turned out that precision guidance was like this.

What about Sun Xiang?

First full of shock, then full of admiration.

He never imagined that Lin Feng's technical attainments were so high, and Leihuo Technology and Industrial Group had mastered such an impressive precision guidance technology. As far as he knew, this technology alone would surpass Pretty Country by a whole body.

Luo Pingfan and others stayed in Leihuo Technology Industrial Group for two days, mainly to study with an open mind, until they felt that they had basically mastered this precision guidance technology, and then left with satisfaction.

Why did Lin Feng share this advanced technology with them?

The main thing is that everyone is for the cause of national defense and military industry, and has a common goal. It is not impossible to guide them appropriately based on the principle of rotten meat in the pot.

In addition, I am also making a profit. Maybe I can really dig some talents from Luo Pingfan and the others. In addition, Luo Pingfan also promised that after the successful design of their missile, the production and manufacturing will be placed in the Leihuo Weapons Branch .

That is to say, although there is sacrifice and sharing of advanced missile guidance technology, there are also rewards, which can be regarded as a win-win situation.

There is no need to worry about leaks and the like. This technology will stop at Luo Pingfan and the others, and will not spread outward, because they are also military industrial units and have strict confidentiality regulations.

With almost full notes, Luo Pingfan thanked him repeatedly before leaving Leihuo Technology Industrial Group.

With this technology, he is sure to develop the air-to-surface missile that the military needs.

Thunderfire Turbofan Corporation.

In the precision casting workshop, several technicians looked serious, because it was the first time for everyone to cast single crystal turbine blades.

The high-pressure turbine blades of this turbofan engine are single-crystal turbine blades, and the low-pressure turbine and free turbine blades use titanium alloy turbine blades.

Single crystal superalloy blades use a very critical technology called nickel-based high temperature single crystal superalloy directional solidification technology.

The high-pressure turbine blades were used in the design verification stage of important and key parts before, but because the turbofan engine company’s precision casting plant was not fully put into production at that time, the batch of turbine blades were cast in the precision casting workshop of Leihuo turboshaft engine.

Now, this turbofan engine has entered the stage of full-scale production of parts and components, and the input volume has reached five units. Leihuo Turbofan Engine Company has to cast single crystal superalloy turbine blades by itself.

Superalloy directional solidification technology is definitely a world-class key technology.

At present, there are very few research institutions and companies that have mastered this technology.

Nickel-based single crystal superalloys have excellent high-temperature properties and are the main materials for manufacturing advanced aero-engine and gas turbine blades.

Because this technology is too difficult and the technical content is too high, there are still very few countries and institutions that have launched this technical research. In more than ten years, in order to meet the design needs of high-performance aero engines, countries will begin to attach great importance to nickel. Research and development of base single crystal superalloy.

If the single crystal superalloys are divided into three generations, the single crystal superalloys that appeared in the 80s are considered the first generation, and the current ones in the beautiful country are the second generation, and the Leihuo Technology Industrial Group is the third generation single crystal superalloys.

The temperature resistance of the third-generation single crystal superalloy is about 3°C higher than that of the second-generation single crystal alloy, and its service temperature can reach about 2°C. At the same time, it also has a very obvious advantage in creep strength.

"Be careful, everyone. Every process step must be strictly in accordance with the process regulations."

The director of the foundry and the deputy technical director came here, especially the deputy technical director repeatedly reminded that everything was strictly carried out in accordance with the process steps and process parameters.

The single crystal superalloy turbine blade is one of the most difficult parts to manufacture among the several parts of this turbofan engine.

Everyone dare not take it lightly.

Every step of the operation was done carefully, and even the atmosphere at the scene was a little tense, but fortunately, nothing went wrong during the whole process.

In order to minimize losses and to accumulate process experience, a total of five sets of high-pressure turbine blades were not invested all at once, but only 100 pieces were invested. .

In case of failure, 100 pieces will be lost, and there are still materials for almost four sets, and there is still time to replenish materials.If it succeeds, there will be at least one qualified single crystal superalloy blade, and the high-pressure turbine blade of the first verification machine is enough.

Directional solidification technology is a delicate task, and it takes time. It was not until the next morning that the 100 single crystal blades for this set were opened, and they were taken out of the mold one by one, and carefully placed next to them for inspection. on the stage.

The first is visual inspection.

Two quality inspectors wore white gloves, held a magnifying glass in one hand, and a flashlight in the other hand, carefully inspecting each piece.

The technical director and the technician in charge of the precision casting workshop were also nearby. The technical director even put on white gloves, and picked up one of the blades and looked at it carefully.

Then, he nodded in satisfaction.

From his professional point of view, there is nothing wrong with this single crystal turbine blade, it is very beautiful, and there is no flaw at all.

Appearance inspection, size inspection, ultrasonic inspection, metallographic inspection, after a series of inspections, a total of 96 pieces were qualified, and only 4 pieces were scrapped.

The pass rate is 96%, which is a very high pass rate.

When the results came out, many technicians and workers couldn't help cheering, it was not easy, this is a world-class technology.

The successful casting of this batch of single crystal superalloy turbine blades means that another batch of extremely difficult parts has been successfully manufactured.

Some parts that are less difficult to manufacture and have a shorter manufacturing cycle are nearing completion, and even a small number of parts have begun to be put into storage one after another.

The parts needed for the first verification machine are slowly accumulating, and the parts with drawing numbers one after another are put into storage. Maybe within a few months, all the parts needed for this verification machine will be manufactured, and the engine can be started. final assembly.

At that time, it is destined to be an exciting moment!

This is the world's top military turbofan engine, which is even better than the beautiful country's F119 engine, and has higher technical content.

Luo Pingfan and others returned with a full load and returned to their unit.

Sitting in his office, Luo Pingfan took out his notebook and flipped through it page by page, digesting and absorbing these technologies in his mind, and the design ideas in his head gradually became clear.

Solving the precise guidance technology of this missile is equivalent to removing one of the biggest obstacles in the way. After spending some time, he is confident to overcome the remaining technical problems.

After looking at it for more than an hour, Luo Pingfan closed the notebook with a lot of enthusiasm, put it carefully into the desk drawer, and locked it with a big lock.

Suddenly, he patted his head lightly, almost forgetting such an important matter.

Lin Feng shared the world's most advanced precision guidance technology with them. In exchange, Luo Pingfan and the others needed to support a group of professional technicians from Leihuo Technology Industrial Group.

He thought in his heart, although there are only 30 to [-] people, it would definitely not work to send some young technicians who have not worked for a few years. It needs a proper mix, and some experienced designers must also be there.

Who are you going to send over?
After thinking about it for a while, Luo Pingfan still felt that he needed to hear everyone's opinions, so they organized a special meeting to have a good discussion.

Not long after the meeting ended, the news gradually spread, and many people talked about it in private.

"Our unit is going to send a group of people to Leihuo Technology Industrial Group."

"To be precise, it's not sending them there, but handing over the organizational relationship and personal files. From then on, they will be regarded as an official member of Leihuo Technology Industrial Group."

"Leihuo Technology Industrial Group is not bad. I don't know what kind of work to do after the past. Could it be engaged in aircraft design and development?"

"I'd like to give it a try. Leihuo Technology Industry Group has a high income, and I heard that it provides housing for free!"

"."

While many technicians were talking about this matter in private, the missile research institute posted an official announcement, and suddenly, it was like dropping a huge stone on the calm water.
