Start with the aviation industry

Chapter 276 is a hot potato, or a huge opportunity!

Hongguang Factory!
Just you!
Why did Lin Feng choose this factory instead of another one after pondering over and over again? It was mainly because of the manufacturing equipment. In this introduction, Lin Feng specifically asked for a list of the main equipment.

The equipment of Hongguang Factory is more advanced, especially the special smelting furnace that can be used to produce titanium-aluminum alloy. It was imported from Germany just last year. It may only be considered first-class in the world, but it should be the best in China. Special smelting equipment.

Although the technical difficulty of smelting titanium-aluminum alloy is not great, and the process is not complicated, with the detailed and scientific smelting process provided by Leihuo Technology Industrial Group, both factories can smelt it, but the equipment is more advanced and the temperature control is more precise. Some, maybe the quality of the smelted titanium-aluminum alloy will be better.

Another thing is that the Hongguang factory is closer to Shenhai City. It is a typical southern factory, while the other one is located in the north, at least a thousand kilometers away.

After choosing Hongguang Factory, Lin Feng picked up the phone and told Xie Kangquan of his decision.

Titanium-aluminum alloys are used in military turbofan engines, and it is reasonable for the military to choose special smelters from them, which also saves Leihuo Technology and Industry Group a lot of work.

Hongguang Factory.

This is a special steel factory built in the first five-year plan of the country. It has a large scale and strong strength. Although it cannot compare with traditional steel companies in scale, more than 2000 people belong to the level of a large factory in the special steel smelting industry.

In the smelting workshop, Li Qingchuan, deputy director and chief engineer, is at the production site with several technicians in charge. Another batch of nickel-based superalloy has been released, and it has cooled down at this time. Workers are marking the furnace number and batch number on each piece of superalloy. Number and so on.

"How is the quality, have you checked it?"

The technical director of the smelting workshop replied, "Mr. Li, all the inspections have been completed, and the pass rate is 96%, which is an increase of 92 points from the 4% last time."

"Well, not bad." Li Qingchuan said with satisfaction, "In the future, we will stabilize the pass rate at more than 95%."

"Okay, we will do our best to guarantee a 95% pass rate."

"Mr. Li, are these nickel-based superalloys for Leihuo Technology Industry Group?" a technician asked beside him.

The nickel-based superalloys produced by them meet the needs of many domestic military enterprises, especially aero-engine manufacturers. For example, several engines of Fenghuang Factory use superalloys produced by Hongguang Factory, and the grades are GH3122 and GH4133.

Li Qingchuan said, "Yes, the user of this batch of high-temperature alloys is Leihuo Technology Industrial Group, which is used for the production and manufacture of LH1500 and LH2000 turboshaft engines."

The scene gradually became lively, and many people were talking about it.

"Sure enough, it was manufactured for Leihuo Technology Industrial Group!"

"I didn't expect that the high-temperature alloys we produced could be used in world-class turboshaft engines."

"I heard that the Leihuo Technology Industrial Group is building a factory in Shenhai City, preparing to produce military turbofan engines. I don't know how this engine will be. Will it also use our high-temperature alloys!"

"."

These conversations drifted into Li Qingchuan's ears, and he thought in his heart, Leihuo Technology Industry Group is developing rapidly, if their turbofan engines also use our nickel-based superalloy, then our factory's efficiency and revenue will be greatly improved A rising tide lifts all boats.

Although he is in charge of technology and basically doesn't care about the operation of the factory, he also hopes that the efficiency of the factory will get better and better.

Seriously inspecting this batch of high-temperature alloys in person, she felt that there was nothing wrong with it, and after some instructions and explanations, Li Qingchuan left the production site with peace of mind.

When I left, I looked at this German equipment and thought to myself, you get what you pay for, and it’s true. In the past, the pass rate of nickel-based superalloys of the same grade was 85%, but now it can reach above 95.

Satisfied, he returned to the office, and just after he sat down to smoke a cigarette, Du Jianguo, the head of Hongguang Factory, came over in person.

He was the top leader, and Li Qingchuan could only be regarded as the third or fourth leader in the factory. Normally, if there was anything to do, Du Jianguo would call and Li Qingchuan would go over.

Unless there is something important!
Seeing Du Jianguo coming in, Li Qingchuan got up enthusiastically and said, "Old Du, why did you come here in person?"

Du Jianguo said with a serious face, "We have received a glorious and arduous task. Just now Director Xie Kangquan personally called and talked to me for ten minutes on the phone."

Li Qingchuan said, "What task, Director Xie actually called to explain it for so long!"

"Old Li, do you know the turbofan engine that Leihuo Technology and Industry Group is developing?"

"I've heard of it, but I don't understand it." Li Qingchuan replied.

He is not engaged in the aviation industry, but in special smelting. At most, he has intersected with the aviation industry. For example, the special metal materials produced by smelting mainly meet the needs of the aviation industry, and he has only dealt with some aviation industry companies.

The turbofan engine produced by Leihuo Technology and Industry Group is extremely confidential, and most people know that there is such a thing at most, and they don’t even know that it is the world’s top military turbofan engine. Research and development of turbofan engines.

The matter of developing the turbofan engine is almost public. The Leihuo Technology Industry Group even built a huge professional factory in Shenhai City with great fanfare. Not long ago, it also recruited many people in the talent market of Shenhai City.

Du Jianguo said, "This is an excellent small bypass ratio military turbofan engine with a thrust of over 160KN and a thrust-to-weight ratio exceeding 12. It adopts many original designs, including vector nozzles. It is currently the world's most Well, the finest military turbofan ever."

These are of course what Xie Kangquan told him on the phone just now, and now I'm just telling Li Qingchuan about these.

"It's so advanced. I originally thought it would be first-class at most. After all, Leihuo Technology and Industry Group has never produced a turbofan engine."

Du Jianguo said, "If Director Xie didn't say these things personally, I wouldn't believe it. Director Xie said that this turbofan engine is not only world-leading, but also very versatile. It can be used by many aircrafts. .”

"You should know about the light all-weather third-generation fighter that is being developed in China. It was originally planned to use a Russian-made engine, but it has now been changed to use this engine. If a heavy fighter is developed in the future, two such engines are enough. That is to say, once it is successfully developed, its market prospect will be huge, and its output is estimated to be very high.”

Li Qingchuan listened carefully and fully agreed with one point.

"The Leihuo Technology Industrial Group is so powerful that it is actually designing and developing a world-leading turbofan engine."

A new generation of materials, a new generation of engines.

Li Qingchuan is engaged in special materials, of course he knows this truth, "For such an advanced engine, it is definitely not enough to use only traditional materials. It is estimated that several new types of metal materials or non-metal composite materials will be used."

Du Jianguo said, "Yes, just now Director Xie called and said about this matter. This engine needs to use a large amount of titanium-aluminum alloy, which accounts for almost one-third of the entire engine's metal materials."

"It's impossible!"

Li Qingchuan's voice was loud, with an expression of disbelief.

He is engaged in special metal materials. He may not be very expert in aero engines, but he is definitely an expert in the field of special metal materials.

Of course he has heard of titanium-aluminum alloys, and he has seen introductions in foreign professional literature. He knows that although this alloy is very strong, it has a very obvious defect, that is, the use temperature cannot exceed 700 degrees Celsius. temperature, the strength will drop sharply.

Another significant disadvantage is that the metal has poor plastic tensile properties at room temperature, which means it cannot be forged like traditional metal materials.

Because of limitations in use, even GE only dares to use it to manufacture low-pressure turbine blades, which account for a small proportion of metal materials in the entire engine.

Knowing this, Li Qingchuan's reaction was so great.

Du Jianguo is not technical. He doesn't know whether this alloy can account for one-third of the entire engine, but it is true that he received the task of smelting this alloy.

"Old Li, we received the task of smelting this kind of titanium-aluminum alloy. Director Xie called and almost issued a military order, requiring us to smelt the first batch of qualified titanium-aluminum alloy within three months."

what!
Li Qingchuan stared blankly at Du Jianguo, completely thinking that there was something wrong with her ears, and she had a huge reaction after recovering.

"Impossible, absolutely impossible, not to mention three months, even three years is absolutely impossible." Li Qingchuan said a little excitedly, "Old Du, do you know that the whole world can only be grasped by GE company initially?" It took several years and at least hundreds of millions of dollars to develop the titanium-aluminum alloy technology."

Suddenly, Du Jianguo was stunned!
Never expected that the technical difficulty is so great!

This is simply difficult to reach the blue sky!
At first, he thought he had received a glorious task, but now it seems that he has taken over a hot potato, and it is still the kind that cannot be shirked.

This is a task assigned by the military, and Hongguang Factory is a military-industrial unit. You can never say that the task is difficult. I will not do it. You can find someone else.

If you can't do it, you have to do it, if you don't do it, you have to do it!
Du Jianguo smiled wryly, feeling like there was a mountain in his heart. If he failed to complete the task within three months, he would be punished. Both he and Li Qingchuan would be punished.

"Old Li, is there really no possibility?"

"Ugh"

Li Qingchuan sighed, "This is an impossible task. To be honest, I have only seen the introduction of this alloy material in foreign literature, and I don't know its specific performance parameters at all, let alone I know the smelting process, not to mention the smelting process, and I have never even seen this alloy material."

Finished!

Du Jianguo was dumbfounded, his face was a little pale.

After a long time, he said slowly, "No matter what, we can only treat dead horses as living horse doctors. Director Xie asked us to go to Leihuo Technology Industry Group as soon as possible, then let's go there as soon as possible, and we will also share our difficulties with Leihuo. Let’s talk about the technology industry group.”

Lin Feng did not say that Leihuo Technology Industry Group would provide a complete set of smelting process, but only said that it would provide relevant technical information.

Xie Kangquan's understanding is that this should be the introduction of titanium-aluminum alloy, or a series of parameters required by Leihuo Technology and Industry Group for this alloy, such as how much strength must be achieved, how much density must not exceed, and the high temperature environment it can adapt to.

In the phone call just now, Xie Kangquan just asked Hongguang Factory to hand over to Leihuo Technology Industrial Group as soon as possible, and start the smelting of titanium-aluminum alloy earlier. As for the three-month cycle, it was proposed by Lin Feng.

The design of this turbofan engine is progressing smoothly. It is necessary to smelt the titanium-aluminum alloy in the next three months or so, because a series of inspections and verifications for this alloy will take time.

Leihuo Technology Industry Group.

Lin Feng turned on his computer again, looked at the technical information on the smelting process of titanium-aluminum alloy, and thought again in his heart, as expected of something produced by the system, the process is very scientific and comprehensive!

Even if Lin Feng is not engaged in special smelting, he knows that the process is very operable. The whole process is very simple and not complicated. There are almost no difficult technologies. As long as the process requirements and steps are followed, ordinary special smelters can do it. .

How about the performance of this titanium aluminum alloy!

The first thing Lin Feng thought of was the word "rolling". It surpassed GE's so-called titanium-aluminum alloy too much, not only in terms of strength, but also in the adaptable environment temperature, which can reach a temperature of 1280 degrees. .

Can adapt to such a high temperature, except for the first-stage high-pressure turbine blades, other high-temperature parts can be made of this alloy.

Of course, if this alloy is to be used to manufacture the first-stage high-pressure turbine blades, it is also possible to carry out some cooling designs, such as hollow blades, air film cooling, or coat the blade surface with a heat-resistant heat-insulating coating.

The more you look, the more satisfied you are.

Lin Feng thought in his heart that this smelting process must be strictly kept secret, and must not be leaked out. If people from Hongguang Factory come over, they must first emphasize to them that the work is confidential. However, they are an old military enterprise, so they should not keep confidential what's the problem.

After reading this handicraft material again, Lin Feng printed it out, bound it himself, and put it in the drawer of his big desk.

How is Serena's design going?
After this thought came to his mind, Lin Feng drove to Leihuo Helicopter Design Institute, and Zhao Mingzhi and Li Guangshu came to report on their work.

"Boss, the general design of Serena Veyron is out, take a look."

After finishing speaking, Zhao Mingzhi spread out the general design drawing signed by the third level on the big table, and then Lin Feng looked at it seriously.

At first glance, it is almost the same as the general design of the Veyron heavy gunship, but after a closer look, some differences are found.

After looking at it carefully, Lin Feng pointed out a few areas that need to be improved, and then said, "Overall, the design is good. It basically follows the design of the Veyron heavy-duty armed helicopter. Even the shape is similar to the Veyron, almost shrunk. version."

"I have no objection to using a lot of the design technology of the Veyron heavy-duty gunship, but you must master it well during the design process. You can't let this foreign trade version of the gunship be too advanced. It is basically equivalent to the performance of the Longbow Apache. Okay, don't overdo it."

Others do their best to pursue high-quality and high-performance designs, but here the situation is the opposite. We must grasp the scale, and the performance is too good.

After explaining something, Lin Feng said with satisfaction, "Your speed is very fast, and the general design will come out."

Zhao Mingzhi replied proudly, "Boss, not only the general design drawing, but also many design drawings have been released."

"The speed is really good." Lin Feng said, "Choose some of those blueprints and send them over, I want to have a look for myself."

After a while, the design drawings of some important and key components were sent over, and there were twenty or thirty copies.

Lin Feng sat down and looked through it patiently. After reading a few copies, he basically understood that the entire design almost completely followed Veyron's technology, no wonder the speed was so fast.

In this way, as long as you grasp the scale, the design work will be very smooth, and Lin Feng is also relieved. The Leihuo Helicopter Design Office now has more than a thousand people. With so many people, it is estimated that Serena's Helicopter will be completed in about half a year. All design drawings are drawn.

After all, there is the technology of Veyron heavy-duty armed helicopters. All the designers can refer to the technology of Veyron. Even the structural design of the helicopter can be used. The same is true for the avionics system. It is enough to simplify some functions.

Lin Feng stayed at Leihuo Helicopter for almost a day, and returned to Phoenix City in the evening. Apart from looking at the design of the foreign trade version of the armed helicopter, he also went to the nearby Leihuo Helicopter Company to have a look.

The production of the foreign trade version of Tianlong is very stable. Still according to the speed of one helicopter after three days, one helicopter after another is manufactured. The exclusive version of Tianlong is also at the same speed. service.

Leihuo Technology Industrial Group received an official letter from Hongguang Factory. Du Jianguo, the head of the factory, and Li Qingchuan, the deputy factory director and chief engineer, will come to discuss the smelting of titanium-aluminum alloy.

After reading the official letter sent by Ding Haixia, Lin Feng said, "Director Ding, on behalf of the company, you call the other party to welcome them. In addition, you go to meet them when the time comes, and arrange their itinerary and hotel."

"Okay, boss."

After watching Ding Haixia leave, Lin Feng thought in his heart that the people from Hongguang Factory are about to come. I don’t know what kind of reaction it will be when the titanium-aluminum alloy is successfully smelted in Hongguang Factory. It is estimated that the aviation industry around the world will be shaken. .

Two days later.

Du Jianguo, Li Qingchuan and their group arrived at Leihuo Technology Industrial Group and sat in the spacious and luxurious reception room. They were all under pressure.

Li Qingchuan even thought in her heart, should I tell Boss Lin later that it is almost impossible to smelt titanium-aluminum alloy.

It's another [-] update, everyone, come to support with a monthly ticket, thank you in advance!
