Start with the aviation industry

Chapter 275 The Coveted Metal Material

Xie Kangquan's reaction was great!

Seeing this, Lin Feng felt inexplicably sad.

The gap between the domestic aviation industry and the developed countries is too large. The number of domestic armed helicopters is small and their performance is also backward. He had such a big reaction when he first heard that he wanted to export an armed helicopter that was almost comparable to the Longbow Apache. .

Lin Feng explained, "Director Xie, with the advent of our Veyron heavy-duty armed helicopter, at least the gap between us and developed countries in the field of armed helicopters has narrowed all of a sudden."

"In addition to the Veyron heavy-duty armed helicopter, the medium-sized armed helicopter that Zhou Yuanliang and the others are designing and developing will also come out. In a few years, the whole situation will be greatly improved. We have both the Veyron heavy-duty armed helicopter and the dedicated medium-sized armed helicopter. .”

After hearing such an explanation, Xie Kangquan felt a little better in his heart, but he still said, "Even so, I still don't want to see such a good armed helicopter being sold abroad."

Lin Feng completely understood his feelings, just like a bitter haha, he was used to being poor all the time, and suddenly he could wear silk and satin, and he definitely couldn't bear to wear it. Thinking about using it myself.

"Director Xie, you may not know the performance of the dedicated medium-sized armed helicopter designed and developed by Zhou Yuanliang and the others."

"Oh, isn't the gunship they designed and developed very advanced, better than your medium-sized gunship for foreign trade?"

"Of course." Lin Feng replied with certainty, "The entire avionics system of this armed helicopter was designed and developed by our Leihuo Technology Industrial Group, and the anti-tank missiles used will also be the same as the Dragon's missiles."

"We estimated that if the comprehensive performance of the Longbow Apache is A, then the comprehensive performance of Zhou Yuanliang and his armed helicopter can reach the level of A+."

"Really, it's so advanced, surpassing the longbow Apache." Xie Kangquan was a little surprised.

In the past, the Longbow Apache was the ceiling among armed helicopters, and it felt out of reach. Now, the Veyron has completely surpassed it, even the medium-sized armed helicopter designed and developed by Zhou Yuanliang and the others has completely surpassed it.

In addition to being pleasantly surprised, Xie Kangquan asked, "Mr. Lin, what about your foreign trade armed helicopter? What level is it?"

Lin Feng said, "Although it will continue to use many of Veyron's design technologies, because it is a foreign trade version, many functions have been simplified, and its comprehensive level should also be A, which means it is basically equivalent to the Longbow Apache."

Hearing this, Xie Kangquan nodded, the overall performance was also A, slightly inferior to Zhou Yuanliang's armed helicopter, so he felt relieved.

"Mr. Lin, what about our Veyron heavy gunship? What level is it?"

Lin Feng said confidently, "It should at least be at the level of S+, and it is not even too much to say that it is at the level of SS."

"Our Veyron is so good!"

Even though he knew that Veyron was excellent and completely surpassed Longbow Apache, Xie Kangquan couldn't help showing obvious surprise after hearing Lin Feng's S+ and even SS's evaluation.

After Lin Feng's explanation, Xie Kangquan finally accepted that this armed helicopter could be exported.

"Mr. Lin, please introduce this foreign-trade armed helicopter to me. After returning to the capital, I will make a detailed report to the higher authorities."

"Ok."

Lin Feng began to introduce this foreign trade version of the armed helicopter to Xie Kangquan in great detail. Although it has not been successfully designed and developed, Lin Feng already has a clear idea in his mind.

He listened carefully, and opened his notebook to record carefully. Sometimes, he would stop to ask a few words.

Lin Feng fully introduced two, three and 10 minutes, and Xie Kangquan recorded several pages. Now he has a relatively comprehensive understanding of this armed helicopter.

"Mr. Lin, many designs of this armed helicopter follow the Veyron heavy-duty armed helicopter, but the size is slightly smaller, the tonnage is smaller, the bomb load is smaller, and the performance is slightly worse."

Lin Feng nodded and said, "Yes, that is indeed the case. It is in the same line as Veyron's design and belongs to the same series."

Xie Kangquan smiled and said, "We can call it Serena."

"It can be called Xiao Weilong." Lin Feng agreed.

Xie Kangquan looked at the design technical outline in his hand, "Mr. Lin, can you make a copy of this design technical outline and bring it back to the capital?"

"Yes, no problem." Lin Feng said straightforwardly.

Leakage does not exist. Lin Feng knew that Xie Kangquan brought a copy back home mainly for the convenience of reporting to his superiors.

This is a world-class armed helicopter, and it is not something Leihuo Technology and Industry Group can export just by saying it.

Everything needs to be determined and approved by the higher authorities, Lin Feng said, "Director Xie, help us lobby after we get back, and let the higher authorities approve the export of this armed helicopter."

"I try my best."

Now, Xie Kangquan finally did not object to the export of this armed helicopter, and promised to try his best to convince the people above.

After the two chatted about the armed helicopter for a while, Xie Kangquan began to pay attention to the military turbofan engine that was being designed and developed.

"Mr. Lin, how is the progress of your turbofan engine design?"

Lin Feng introduced, "At least one-third of the design work has been completed, and many design drawings have been drawn up, including design drawings for some important and key components."

Xie Kangquan said in admiration, "As expected of Leihuo Technology Industrial Group, this speed is unmatched by anyone, it's too fast."

It usually takes ten or eight years for others to design and develop a turbofan engine, but Leihuo Technology Industry Group estimates that it will take one or two years. This is only a few months, and one-third of the design and development work is over.

Lin Feng said, "The engine of this turbofan needs several new materials, including Ti-Al alloy materials. How about your help in finding a special smelter for us?"

Xie Kang said, "Even if you don't ask, I will tell you about it. We have selected two special smelters. Here are their information."

It turned out that he had already prepared, took out the information from the briefcase, and put it on the coffee table in front of Lin Feng.

Lin Feng flipped through the documents and said with great satisfaction, "They are all state-owned enterprises with military backgrounds. Such enterprises are good, we can rest assured!"

"The information is given to you, take a look first, and call me after you determine which company."

Xie Kangquan stayed in Leihuo Technology Industrial Group for two days, which was the longest time. In the past, he usually only stayed for half a day or a day.

His harvest is also huge. Not only did he personally see the final assembly of the first Veyron prototype, but he also learned about the production and manufacturing of the exclusive version of the Veyron, the situation of the foreign trade version of the armed helicopter, and the design and development of the turbofan engine. progress.

He went back, and it is estimated that he will make a detailed report on this series of situations.

.........

Deep Sea City.

The huge professional turbofan engine manufacturing plant has been under construction in full swing. There will be a small change every day, and a big change in three to five days.

Here is an explanation of what is called deep sea speed!

The huge factory area of ​​more than 800 mu has begun to take shape. For example, the main road in the factory area has been built and paved with asphalt for the first time. Many vehicles are already driving on it, transporting various building materials.

For example, the gate of the factory area has been built, which is very grand, fully 50 meters wide, and the long telescopic door has been installed. More than a dozen gold-plated characters of "Leihuo Technology Industrial Group Turbofan Engine Company" are very eye-catching.

Several factory buildings in the factory area have been capped and have begun to enter the stage of water and electricity installation, and the remaining few buildings are almost capped.

Each factory building is of a high standard and has a huge area. The area of ​​several manufacturing factories is more than [-] square meters, and the area of ​​the turbofan engine assembly factory is more than [-] square meters.

Today, Liu Shunkang, head of the human resources department of Leihuo Technology Industrial Group, led a team to Shenhai City and began to recruit talents for the turbofan engine company.

The senior managers of this company were recruited through headhunting companies. It has to be said that Shenhai City has come to the forefront of the country in this respect, and there are many very mature and powerful headhunting companies.

Leihuo Technology Industry Group offers high salaries. For example, the salary of the general manager of the turbofan engine company is not less than 50 yuan per year, with cars and assistants, and housing of more than 150 square meters.

It is now 1994, and this kind of treatment is very high even in Shenhai City. Of course, the requirements of Leihuo Technology Industry Group are also very high.

It not only requires rich management experience in aero-engine enterprises, but also requires a series of requirements such as high education.

Even if the threshold is high, there is no need to worry about the remuneration. With the development of the economy, the most indispensable thing in society is talents.

Liu Shunkang personally led the team, and was mainly responsible for the recruitment of middle and low-level managers and related technicians of Leihuo Turbofan Engine Company.

The construction of the factory area has begun to take shape, and he will also build the organizational structure and framework of Leihuo Turbofan Engine Company.

The talent market is very lively.

At least hundreds of companies are recruiting here, and the recruitment position of Leihuo Technology Industrial Group is very eye-catching, and the scale is also very large.

Including Liu Shunkang, there are a total of more than a dozen people, and the preparation work is very sufficient. Not only the introduction of Leihuo Technology Industry Group and Leihuo Turbofan Engine Company with pictures and texts, but also the introduction, requirements, salary and so on of each recruitment position.

The recruitment of Leihuo Turbofan Engine Company has attracted a large number of people. In the mainland, college students are still paid and assigned, and there are very few job-hopping, but Shenhai City is different, there is no shortage of college students at all.

Because the remuneration offered is good, not only do you not worry about not being able to recruit people, on the contrary, the threshold can be raised appropriately.

For example, the general management positions of Leihuo Turbofan Engine Company require a bachelor’s degree and more than three years of management experience in manufacturing enterprises. The requirements for technicians are even higher. Not only a bachelor’s degree is required, but also a professional title of engineer is required. Those with a deputy senior professional title can be admitted first. .

Even though the threshold was relatively high, it still attracted a large number of people to apply for the job. There was a long queue here. Although Liu Shunkang brought over a dozen people, he was still very busy.

"I know Leihuo Technology Industry Group, a very good aviation industry enterprise!"

"I didn't expect that they would build a factory in Shenhai City, ready to produce turbofan engines!"

"This treatment is too good, the salary is already enviable, and there are various bonuses!"

"It's a pity, I'm just a freshman who has just graduated from university for two years, otherwise, I really want to try my luck!"

"..."

Lin Feng received a report call from Liu Shunkang.

More than 100 middle and low-level management personnel and dozens of technical personnel have been recruited for Leihuo Turbofan Engine Company.

The headhunting company has also found a batch of candidates, and he will send the information for Lin Feng to review and select.

After answering the phone call, Lin Feng thought in his heart that the framework of the turbofan engine company can be built, the company can start operating, and a series of things before manufacturing can be entrusted to them, instead of the group doing it by themselves.

Lin Feng is not worried about the production of this turbofan engine. Not only does it have a large-scale production and manufacturing plant, but now, the framework of the turbofan engine company can also be built.

What Lin Feng has to do is to complete the design of this turbofan engine as soon as possible, and then start the manufacturing and design verification of some parts.

Of course, there are several new materials for manufacturing.The soldiers and horses did not move, but the food and grass went first.The same is true for the manufacture of new aero engines, and the material problem must be resolved as soon as possible.

Titanium-aluminum alloy is a new type of metal material required for this engine, and this alloy needs to be produced before the design of the aeroengine is completed.

The system provides detailed manufacturing processes for these new materials. As long as you find a factory with certain strength and give them the process information, you can manufacture the new materials required by this turbofan engine.

Lin Feng has no plans to build his own factory to produce these new materials. That would be too troublesome and the cycle would be too long. There is a relatively complete industrial system in China, so it is not difficult to find relevant and suitable manufacturers.

For example, Xie Kangquan, on behalf of the military, took the initiative to help Leihuo Technology and Industry Group select two special smelting enterprises that produce titanium and aluminum alloys.

They are all established companies with military backgrounds, and their scale and strength meet Lin Feng's requirements.

After looking at the introduction materials of these two special smelting companies, Lin Feng said to himself, both companies are good, it is really hard to choose.

Forget it, don't choose for now, first get out the process data of titanium aluminum alloy.After making up his mind, Lin Feng sat in front of the computer, got out the titanium-aluminum alloy smelting process information in his mind, and started typing on the computer.

Titanium-aluminum alloys exist like a ceiling in the field of aero-engines. Looking at the whole world, GE in the beautiful country has initially grasped them. For example, the famous Rolls-Royce company has just started research at this time, and it is still far from practical application.

Why do you say that GE has a preliminary grasp, because although they have begun to use this alloy on the engine, there are still some limitations in the use of this alloy, and the requirements for the use environment are very harsh, so it cannot be fully promoted.

A new generation of materials, a new generation of aero-engines!

This is not false at all!

For example, the turbofan engine of Leihuo Technology Industry Group can become the ceiling of the world's military turbofan engines. It uses several new materials, the most important of which is the use of titanium-aluminum alloy.

Titanium-aluminum alloy, the new darling in the field of aero-engine!
Compared with traditional metal materials, it has so many advantages that it is simply a dream metal material!

First of all, its density is small, with a weight of only 3.9 grams per cubic centimeter, while the nickel-based superalloy is 8.5 grams, which is more than double the weight.

That is to say, for parts of the same volume, if nickel-based superalloy is used, if it weighs 10 kilograms, then if titanium-aluminum alloy is used, it will weigh less than 5 kilograms.

In addition to low density, titanium-aluminum alloy also has the following characteristics:
Gao Biqiang, Gao Bigang!
Corrosion resistance, wear resistance, high temperature resistance! ! !
It is really a coveted metal material in the field of aero engines.

It is also the only lightweight metal material that can be used in an oxidizing environment above 600 degrees Celsius except ceramics.

Although the nickel-based superalloy can also adapt to the oxidizing environment above 600 degrees Celsius, it has a high density, as high as 8.5.

At the end of the 80s, GE Company discovered this alloy and spent a lot of money on research. It has achieved good results. Last year, the turbine blade made of titanium-aluminum alloy was verified and tested on the CF6-80C engine, and the effect was not bad.

But they also found that this metal has great limitations, such as its low tensile plasticity at room temperature, and its strength will drop sharply if the temperature exceeds 700 degrees Celsius, which limits its replacement of nickel-based superalloys at better temperatures.

What about the titanium-aluminum alloy provided by the system?

Lin Feng just wanted to say one thing, the products produced by the system must be high-quality products! ! !
The service temperature of GE's titanium-aluminum alloy cannot exceed 700°C, while the system's titanium-aluminum alloy can handle the high-temperature oxidation environment of 1200°C with ease.

If people from GE know about this, they will definitely go crazy with envy. They spent hundreds of millions of dollars and took several years to develop titanium-aluminum alloys that can only adapt to a temperature of 700 degrees Celsius. The adaptation temperature is directly up to 1200°C, to be precise, it can adapt to the high temperature oxidation environment of 1280°C.

Too awesome!
The turbofan engine designed and developed by the system uses a large amount of this titanium-aluminum alloy, accounting for almost one-third of the entire engine.

Is it difficult to smelt such an awesome alloy?

No, no, it is not difficult at all, as long as the smelting process and parameters provided by the system are strictly followed, any special smelter with a certain scale and strength can complete it.

It only took Lin Feng half a day to input the complete smelting process of titanium-aluminum alloy into his computer.

After the smelting process is completed, the next step is to choose a smelting factory. Who is better to choose? Lin Feng picked up the introduction materials of these two special smelting factories and looked at them.
