After receiving a call from Zhang Ping, Tang Fei thought that he had learned about the first drone entering the assembly of the whole machine, but he immediately felt that Zhang Ping's tone was wrong.

Zhang Ping's tone on the phone was low and solemn.

Tang Fei immediately realized that it was not the first drone to be assembled, but there might be something else.

Sure enough, Zhang Ping immediately said: "Mr. Tang, Factory 336 is in trouble, do you know?"

I really don't know this, during this period of time, Tang Fei basically focused on the production and manufacturing of drones, especially the assembly of the first drone.

Tang Fei immediately asked with concern: "Director Zhang, what happened to Factory 336?"

Zhang Pingdao: "Mr. Tang, you should also know that the level of our domestic material industry is slightly behind, and some materials needed for aero engines, especially new advanced aero engines, can only rely on imports for the time being, and the same is true for this engine of the UAV." ”

Tang Fei knew about this.

One generation of materials, one generation of aero engines.

Without high-quality materials and a strong material industry to support it, it is very difficult, if not impossible, to build advanced aero engines. The UAV's engine is highly technological, with excellent comprehensive performance, and is definitely the best medium-sized turbofan engine in the world.

This is a system developed successfully engine, the system fully takes into account the actual situation of the industrial level of Chinese materials, as far as possible not to use imported materials, but there are several key materials are no way, only foreign countries, must rely on imports.

These materials are also indispensable metal materials for the production and manufacture of key engine parts, such as titanium alloy materials for the production of compressor parts, and high-temperature alloy materials for the production of turbines.

At the beginning of the trial production of the engine, there was a lack of these materials, and the military came forward to solve some of them through some channels, and in addition, Tang Fei exchanged some from the system, and the engines in the early stage were not short of materials for the time being.

In order for the engine to enter stable mass production, it is necessary to have a stable material supplier, whether it is the military or Huaxia Aviation Industry Group, they are actively contacting overseas manufacturers.

Finally, I got in touch with a very powerful special steel factory overseas, which can produce several metal materials needed to manufacture drone engines.

The two sides have been negotiating, many things have been basically negotiated, and a formal contract will be signed soon, and the material problem of mass production and manufacturing of engines in the future will be basically solved.

But things suddenly took a turn for the worse.

Just yesterday, this special steel factory suddenly said that it did not want to cooperate, and would not export those metal materials to Huaxia, and suddenly, many people attached great importance to it, including the military are taking the initiative to contact the top management of this factory, but there is no progress in the matter.

This should be the case.

Without these imported metal materials, what will happen to the mass production and manufacturing of engines in the future?

Something big.

Zhang Ping immediately called Tang Fei to explain the situation, and after knowing this situation, Tang Fei's face sank slightly, and he said in his heart, without his own powerful material industry, he was really aggrieved.

"Mr. Tang, a total of 5 imported materials, two titanium alloy materials, three superalloy materials. Among them, two titanium alloy materials and one superalloy material are relatively easy to say, and we have carried out research in China many years ago, and it is estimated that it will be possible to get it out in another one or two years. ”

"The key is to produce and manufacture single crystal superalloys for turbine blades, as well as powder superalloys for turbine discs, these two metal materials are technically very difficult, even if we invest a lot of money and gather specialized talents to tackle key problems, it is absolutely impossible to do it in five or six years. ”

Tang Fei couldn't be clearer about these two superalloys.

At the beginning, it was exchanged from the system by itself, and Factory 336 had these two superalloy materials to produce the current drone engine, but the number was limited at the beginning, and only five or six engines could be produced.

Five or six units are far from enough.

For such an advanced and outstanding large UAV, the military must equip at least dozens of them, each UAV needs two engines, and the 336 factory also produces at least 100 such engines.

It is difficult for a good woman to cook without rice, and without these two superalloy materials, they can only look at the sky and sigh.

Originally, these two materials could be imported from an overseas special steel factory, and the matter was basically discussed, without thinking that the other party suddenly changed his mind.

The matter is important, and at this time, it is estimated that the top brass of the military are alarmed.

Tang Fei said slowly: "Director Zhang, it seems that the situation is very bad. ”

Zhang Ping sighed and said: "It's not just bad, it's just forcing us into a dead end, without these two superalloy materials, Factory 336 will soon run out of food." ”

The first engine of the 336 factory is undergoing a 300-hour long-term assessment test, the second engine has entered the assembly stage, and many parts of the third engine have also been manufactured, and the parts of the fourth and fifth engines are currently being manufactured.

At this rate, they will really run out of food soon, and they will soon face the situation that the follow-up engine will be processed without materials for parts.

Tang Fei also felt a little strange, why did the things that had been discussed suddenly change hexagrams? So, Tang Fei asked.

Zhang Ping did not hide it, and said slowly: "According to the current situation we have, someone should be putting pressure on this special steel factory behind the scenes, no, it should be putting pressure on the country where this factory is located." ”

There is pressure behind the scenes to prevent the sale of these superalloy materials to Huaxia.

Suddenly, Tang Fei thought of Hao Hongxia's trip to the United States not long ago, and was estimated to be difficult by American security personnel at the New York airport.

Could it be that there is a connection between these two things, could it be that someone has extended his black hand to Jiuzhou Industrial Group behind his back and wants to hinder the development of Jiuzhou Industrial Group.

If this is the case, then the black hand behind this may have something to do with the United States.

After having such a guess in his heart, Tang Fei said the guess in his heart, and suddenly, this aroused Zhang Ping's vigilance.

"Mr. Tang, if you say so, there may be a connection between the two, I will report to the military leadership, and our military will carry out an investigation, and tell you the results as soon as there are results. ”

Tang Fei nodded.

The military is strong, Tang Fei is naturally convinced, if the military really launches a secret investigation, then the truth of the matter should be clear.

After promising that the military would investigate the matter, Zhang Ping was still worried about the situation at Factory 336 and was very worried that they would run out of food.

"Mr. Tang, our engine manufacturing is being carried out smoothly, and there will be a large number of these two superalloy materials in the future, I wonder if Mr. Tang can think of a way. ”

The single crystal superalloys and powder metallurgy superalloys required by the previous engines were all provided by Tang Fei. This time, Zhang Ping also regarded a dead horse as a live horse doctor and asked Tang Fei.

What if Tang Fei has a way?

When Zhang Ping was very happy, Tang Fei smiled lightly, and then said: "Director Zhang, our Jiuzhou Industrial Group still has some channels overseas, let's give it a try, maybe we can get back some of these two superalloy materials, but it can only solve the urgent need, and the large number of superalloy materials needed for mass production and manufacturing of engines in the follow-up may not be enough." ”

Zhang Ping's heart finally lightened a little, "It's better to get some back than nothing, we can only take one step at a time, and solve the urgent need first." ”

This has come to this, and it can only be done for the time being.

Perhaps after this incident, the state will increase investment in the materials industry, especially the research and development of some materials needed by the aviation industry.

Perhaps this will also invisibly accelerate the improvement of the level of Huaxia's material industry, so that Huaxia's material industry will gradually develop.

Tang Fei dared to make such a promise, of course, by relying on his "god-level industrial master" system, spending a certain amount of gold coins, and exchanging some from the system.

As for saying that there are some channels overseas, that is just a pretext, and I believe the military will not delve into it. Tang Fei thought in his heart, someone wants to jam his neck and create obstacles to the production of drones, and I am afraid that this calculation is wrong.

After the two chatted for a while about these two scarce superalloy materials, Zhang Ping finally asked: "Mr. Tang, how is the assembly progress of our first drone, and now it should be about to enter the assembly of the whole machine." ”

Tang Fei said: "Director Zhang, I was about to call to tell you that the first UAV was successfully assembled this morning, and we plan to complete all the assembly work before September 1, complete the first round of acceptance of the military joint expert group before September 10, and make the first flight before September 20, so that this UAV can fly into the blue sky." ”

Hearing that the progress is so fast, Zhang Ping is happy and more determined in his heart to think that he must report the situation to the leaders, and also suggests increasing the development of the domestic material industry, supporting the development of the domestic material industry, so that the production and manufacturing of drones will no longer face the situation that it is difficult for a smart woman to cook without rice.

……

Plant 336.

It was already dark at night, but the lights were bright in one of the conference rooms, and not only all the high-level executives were attending the meeting, but also some important middle-level officials were also in attendance.

The meeting was personally presided over by Yu Shaoguang, the leader of the 336 factory.

The overseas special steel factory no longer cooperates with them, and the 336 factory bears the brunt and has the greatest impact. Soon they will find themselves in a situation where there is no material available.

The situation was gratifying, the first engine performed exceptionally well in the 300-hour long-term assessment test, the second engine also entered the final assembly, and the production and manufacturing of the subsequent engines were also relatively smooth.

I thought it would get smoother and smoother, but I didn't think about being drunk as a head.

In the conference room, the atmosphere was solemn and dull.

……

Today's three watches, the third watch is sent, thank you for your support!
