Under the leadership of Li Tianfeng, we came to this large CNC gantry milling machine, which is one of the two large CNC gantry milling machines imported from Germany, with a maximum stroke of more than 50 meters, and at present, the main beam of the J-30 fighter is being processed.

This is a very critical structural part, the structure is complex, the precision is very high, the material is a new titanium alloy material, this titanium alloy, is the Tianfeng Technology Company Materials Engineering Research Institute successfully developed, has been widely used in the "black ghost" UAV.

This is a titanium alloy with high strength, high toughness and high damage tolerance, if you look at this titanium alloy under the electron microscope, it can be seen that the microstructure of this titanium alloy is a standard cube, which is very regular.

The J-30 fighter widely uses various composite materials, such as the "Hercules" material, but considering the rigidity requirements of the aircraft's main beam, Li Tianfeng adopted this new titanium alloy.

On the machine tool, a main beam is being processed, and the alloy milling cutter is processing parts at high speed, because the machine tool is too large, this processing is basically open, and everyone stands next to the machine tool and can see it clearly.

The main beam has been processed for most of the time, and it can be seen that the complex structure of the main beam has stiffeners in many places, and some places are simply honeycomb structures, with a wall thickness of less than one millimeter.

With such a thin wall thickness, everyone's impression may be that the structure is too weak to withstand any force, but in fact, this is not the case.

The advanced design structure is placed there, the rigidity of this main beam is very strong, and the various external forces it can withstand are not visible by impression.

Everyone walked to the side of the machine tool, and Zhou Ding said: "Boss, this main beam has been processed in this process for two days, and it will take another day to complete the processing of this process." ”

The processing of large structural parts of aircraft often requires dozens or even hundreds of hours of processing in one process, such as some aluminum alloy structural parts. The blank is directly made of aluminium ingots and very thick aluminium plates, which are finally processed into very light structural parts, which require a large amount of material to be removed.

Li Tianfeng nodded, looked at the processing situation and said, "The processing seems to be pretty good." ”

Zeng Qinghai is responsible for the processing technology, the leader of all process technicians of Tianfeng Technology Company, Zeng Qinghai said: "Boss." The processing of this part, the original process specification is you personally reviewed, we have taken a lot of detours, the first processing, each process is also processed well, this process is believed to be the same. ”

Some of the key parts of the J-30 fighter and the processing technology regulations of the key parts were personally reviewed by Li Tianfeng.

The processing technology specification of the main beam was also reviewed by Li Tianfeng himself. Li Tianfeng was very impressed, so he came here to take a look at the processing situation.

Li Tianfeng nodded, and then said: "The processing technology and processing quality are good, but there is also a lot of room for improvement. ”

Zeng Qinghai hurriedly said: "Boss, our process technicians have always adhered to the tradition. The problems exposed in the trial production process of the parts were recorded one by one. After the processing of a batch of parts, everyone will focus on perfecting and improving the processing process. ”

Li Tianfeng nodded, and saw a large machining center not far away, Li Tianfeng led everyone over again.

This is an imported large-scale machining center, on which a siding-shaped structural part is being processed. Li Tianfeng recognized this part at a moment.

This is a structural part made of "Hercules", which will be assembled on the main beam of the aircraft in the future, and there are many structural parts on the main beam, and this is one of them.

Next to the machine, there are two machined parts. The parts are relatively large, but the parts are very light, and Li Tianfeng easily picked them up with one hand.

Picking up the parts and looking at them, Li Tianfeng nodded slightly.

Zeng Qinghai also said: "Boss, the parts are processed well. ”

Lei Yong said: "It would be better if it could pass the static test and fatigue test." ”

The trial production of parts of the J-30 fighter is to verify and improve the processing technology on the one hand, and on the other hand, it is necessary to do a series of tests and verifications.

The processing of the parts is qualified, but the size is qualified, whether it meets the design requirements, such as force requirements, anti-fatigue requirements, etc., which requires a series of tests.

The parts are successfully processed, and they can pass a series of tests, and the parts of this drawing number are basically trial-produced.

In the past few days, Li Tianfeng's focus has been to take a look at the production and manufacturing workshops of the Chengnan base and take a look at the trial production of various parts of the J-30 fighter.

A few days later, a group of representatives of country XX arrived at Tianfeng Technology Company accompanied by the military, and Li Tianfeng led several high-level officials to personally receive the representatives of country XX.

Country XX is one of the five largest oil producers in the Middle East, was once the second largest exporter of the Organization of the Petroleum Exporting Countries (OPEC), and the country also retains the world's largest untapped land oil field.

Country XX is not only a big oil country, but also its air force is not weak, and its scale is relatively large.

At present, the country's air force has a total strength of about 65,000 (including 15,000 air defense forces), 12 ground attack fighter squadrons, 10 fighter squadrons, and more than 600 combat aircraft of various types, including advanced F-14 and MiG-29 third-generation fighters.

It is only because of the bad relations with the United States that the planes owned by the Air Force have not been able to obtain standard spare parts and effective technical maintenance for 20 years, and if this continues, many aircraft are estimated to be unable to take off.

Fighters are urgently needed, especially more advanced fighters, and Tianfeng Technology's J-18 fighters are just right for the country's appetite.

Unable to buy fighters from Western countries, let alone from the United States, Tianfeng Technology Company has become the preferred target, after some negotiations, the top level reached a series of deals, the country can finally order J-18 fighters as desired.

Tianfeng Technology Company, in a large conference room, thunderous applause even spread outside the conference room.

Li Tianfeng looked happy, and was exchanging contracts with the representatives of XX country, and then shook hands warmly, and after some negotiations, the contract was officially signed.

420 J-18 fighters!

This is the largest transaction since the export of the J-18 fighter, and the largest order received, Li Tianfeng was prepared, but he was far from expecting that the other party would order such a fighter at one time.

After sending off the XX country and his party, several executives of Tianfeng Technology Company talked about this matter, and everyone was happy, so far, everyone almost couldn't believe it.

Yang Xianfeng rarely rushed from Tianxin City to hold a high-level meeting of the company, after the meeting, Yang Xianfeng, Zhang Can, and He Baitao did not leave the conference room in a hurry for the time being, but chatted.

Yang Xianfeng said: "I can't believe that this morning, the company signed an order for 420 J-18 fighters with XX country. ”

Zhang Can said: "Yes! 420 J-18 fighters, it's a little hard to believe. ”

He Baitao said with a smile: "I guess the other party wants to give his own air force a big change and eliminate all the old fighters in the past." ”

Yang Xianfeng said: "Bai Tao, there is really such a possibility, although the opponent's fighters have hundreds of planes, most of them are second-generation fighters, and there are only dozens of third-generation fighters. ”

Zhang Can said: "It's very likely that this is the case, I heard that many of their fighters are almost unable to fly because they have no spare parts to replace." ”

The three of them chatted about this big order, and internationally, many countries already knew about it, including the United States.

The United States reacted quickly and immediately declared that China's move would greatly disrupt the balance in the Middle East and bring about factors of extreme instability to world peace and stability.

It's just that the Chinese side scoffs at this tone of the United States, and why don't you consider balance and world peace and stability when you make large-scale arms sales yourself?

Office of the President of the United States.

Several people are personally reporting the situation to the president, among them, the director of the CIA said: "Your Excellency, we have investigated clearly, XX country and Tianfeng Technology Company have signed a formal order contract, and we speculate that the number of J-18 fighters may exceed 300. ”

Hearing about the number of 300 planes, the face of the US president changed slightly.

After a few seconds of silence, the US president said: "How does the performance of the J-18 fighter compare with our F16?" ”

A US military general who had not spoken for a long time said: "Your Excellency, if the performance of the J-18 fighter is really as announced by Tianfeng Technology Company, then the overall performance of this fighter will far exceed our F16 fighter, and even reach the edge of the fourth-generation fighter." ”

Far more than the F16 fighter.

The performance is close to that of the fourth generation fighter.

The face of the President of the United States changed slightly.

A senior U.S. official next to him said: "Your Excellency, the Chinese side attacked the IS organization last time, and this time it sold a large number of J-18 fighters to country XX, and China is interfering in Middle East affairs more and more frequently, and if this continues, it will greatly damage our interests in the Middle East, and we need to take countermeasures." ”

The President of the United States said slowly: "Yes, we have to take countermeasures, and we can't continue like this." ”

Hearing this, everyone in the office was happy, and some even showed happy looks.

………

Tianfeng Technology Company.

Li Tianfeng did not know the plans of the US side, and this was not something that Li Tianfeng needed to care about.

At present, Li Tianfeng has only one goal, that is, to make full efforts to develop the two fighters of the J-30 and J-18 as soon as possible.

Tianfeng Technology Co., Ltd. is in full swing, carrying out the development of these two fighters, and the international turmoil is surging, and a major event has happened, which has attracted everyone's attention at once.
