Maybe in addition to the cooperation of the panda, there is also the cooperation of the SU-27 of the former Soviet Union, Shen Fei basically does the work of self-research and development, in many ways, Shen Fei wants to break this dilemma, but it is difficult, because Shen Fei is responsible for many national special research and development projects.

In this regard, Cheng Fei is completely different.

In the mid-eighties of the last century, Pakistan felt that its air force could not withstand India's air force and began to look for collaborators.

The initial choice was not a J-7 fighter, but an American F-16 fighter, but the price offered by the United States was too high.

Pakistan couldn't accept it, and finally turned to the Phantom 2000, and the talks were very smooth, but in the end it was still yellow.

Of course, Pakistan also sought the cooperation of the Soviet Union, but at that time, the Soviet Union could not even take care of itself, so naturally there was no time to take care of the minibus.

In the end, the minibus sought the cooperation of Huaxia.

The cooperation project was preliminarily finalized and approved as the FC plan.

Due to many reasons due to the collapse of the Soviet Union, the project was stopped, and in 1991, Huaxia started the project again, and the minibus was very confident in this and invested in the project instead.

Thunder is a very successful project, and Cheng Fei has also opened up the international market with the help of Thunder.

After the success of Xiaolong, Cheng Fei received many cooperation and opening projects from other countries.

Chengfei can be said to be the military enterprise with the most contact with the world's aircraft military in China, which is why Weilong's R&D and manufacturing are on Chengfei, because Chengfei has enough experience.

And J-31 is Shen Fei. In fact, many people say that Shenfei does not have the conditions to develop vertical take-off and landing fighters.

And the result? Although it was developed. But there is no rapid test like Weilong, test flight, until it is finalized.

The Weilong and J-31 are almost simultaneous and public projects, which belong to the fourth generation of Huaxia stealth fighters.

And until now, the Veyron has been finalized and mass production has begun, and what about the J-31? Only a few test flights were announced, and there were no results. Some netizens even said pessimistically. The J-31 project has already failed.

Weilong succeeded, but J-31 failed, the same two pillars of China, but the result was completely different.

And when Zhu Lan chose to cooperate, he chose Cheng Fei not Shen Fei, because Zhu Lan did not have much confidence in Shen Fei's technology, and Shen Fei was responsible for many countries' secret projects, which was another important reason why Zhu Lan did not want to cooperate with Shen Fei.

The project bid failed, and Shen Fei was very angry. Because this is a breakthrough, and now this breakthrough has been taken away by Cheng Fei.

And now, the nightingale was taken down by Cheng Fei again, and Shen Fei didn't even give him a chance to drink soup. Shen Fei was naturally annoyed.

And now, if the nightingale can't break through, plus Shen Fei is fanning the flames on the side, maybe the nightingale will have to be handed over to Shen Fei to imitate.

At this point, Cheng Fei's people know that it is precisely because of this that the imitation of the nightingale has always been dedicated. But despite this, the imitation still failed.

There are many reasons for failure, materials, engines, engines, shell coatings, and so on.

Although Zhulan has reduced the performance of the Nightingale and replaced the engine, it is still a very serious challenge for Huaxia.

The technology that Zhu Lan gave to the military Nightingale was not at all worse than that of the fifth-generation aircraft of the United States, and it surpassed the fifth-generation aircraft of the United States in many performances.

The Nightingale itself was made according to the fifth-generation aircraft of the United States, and technically it was completely optimized according to the technology of the Americans, and its own technology was added to achieve the existence of the Nightingale.

Zhulan has reduced some of the technology, and the rest is still very advanced technology.

Although Huaxia has narrowed the technological gap with the United States over the years, the gap still exists, not only in terms of design concept, but also in material manufacturing and engines.

Nightingale Zhulan only provided part of the information, but did not provide all the information, which brought huge trouble to Cheng Fei to imitate the nightingale.

Now that we haven't even figured out the technology, how can we apply these new technologies to other aircraft?

The military is very tempted by the nightingale's engine technology, and if the nightingale's engine is transferred to Weilong, the performance of Weilong can be improved by at least 1.8 times, which is still a conservative estimate.

But Zhulan didn't give all the engine technology, only gave a part of the technology, and it was difficult to make an engine like a nightingale, although it could be done, but it was very difficult.

Although Huaxia is technically strong, it is still not good in some aspects.

The nightingale made by Zhulan has two days, which is an incomparable condition in China.

The first point is that the full intelligent manufacturing, the manufacturing of the nightingale is all responsible for the red queen, from design to manufacturing, all of them are made by the red queen control machine.

It can be said that the nightingale is completely intelligently manufactured, and Zhulan only put forward his own requirements on the nightingale, and the red queen designed it.

The second point is that there is no place in the world where the manufacturing equipment in the blue base can be compared.

The equipment below the four underground floors of the blue sky, except for a small number of world-advanced equipment, most of them are from the future world or the world with an interstellar background, and in terms of technology alone, they are twenty to one hundred years ahead of the earth.

I'm afraid that even the equipment of the aliens in the legendary Area 51 can compare to the equipment in the Zhulan Blue Base.

It is the nightingale made under such equipment that can be very easy, but when it is put on the Huaxia side, the difficulty is multiplied.

It's like in modern times you build a large airliner, that's fine, a lot of factories can make a big airliner.

But if you put some of the materials and samples in the World War II period, even if you send these samples and materials to Germany, which was the most powerful technology at that time, it is impossible to imitate them in a short period of time.

And now this is the case with the nightingale.

The nightingale made with future technology, Huaxia wants to imitate, it is very difficult, although many of them are like the earth's technology, but in manufacturing, it is really made of future technology, which is very difficult to put in Huaxia, if you want to imitate.

The material alone is enough to stump Huaxia.

"I also know the problems we are facing now, but Nightingale does have a lot of problems, the material information given by Zhulan, our equipment can't be processed at all, we need S-level equipment to process it, and that kind of equipment, we have, but we can't process large castings, this has to be cooperated with above, we need large-scale S-level equipment to process the shell casting of the nightingale, otherwise, the index will not reach the original sixty percent at all, not to mention the stereotype, even the sky is a strict problem!"

Yu Ziqian naturally knew the problems that Cheng Fei was facing now.

Although Yu Ziqian is only responsible for development, several directors of Cheng Fei also told Yu Ziqian about the problems faced by Cheng Fei, and wanted Yu Ziqian to understand that the problems faced by Cheng Fei are not small.

Although he is the chief engineer, Yu Ziqian still knows Cheng Fei's policy, and adjusts the research and development time of the project at any time, it is in this way that Cheng Fei can complete many projects perfectly, which has a lot to do with Yu Ziqian's strategy.

Cheng Fei is not as strict as Shen Fei internally, and on many issues, Cheng Fei will listen to the opinions of the company's internal employees and work together with the company's employees.

Cheng Fei's take-off is entirely because Cheng Fei himself is united and there will be no drag.

And Shen Fei is completely different.

In the context of Shen Fei, it is destined that the company itself has a lot of problems, like what layman commands insiders is small.

Although established at the same time, Cheng Fei in the eighties of the last century, when the president of the country threatened to reform and open up, began to try to change, no way to change, the industrial center in the north enjoys the best equipment, the best personnel, the best projects.

Cheng Fei became a second mother, relying on the country, he could only barely survive, and the only thing was reform.

Cheng Fei succeeded, attracted comrades from the minibus on the super 7, and established an international cooperation project, borrowing times, Cheng Fei took off, and when Shen Fei came back to his senses and wanted to reform, the problems he faced were too strict.

"There are only two of the best things to do right now!"

"What's the solution? As long as you can complete the nightingale, I'll help you do it no matter how difficult it is! "Now one of the Nightingales has been dismantled for study, and the other has been used by the military for test flights, and more and more people know the news of the Nightingale, and by now, there are hundreds of thousands of information circulated by the Nightingale.

Moreover, the military also openly installed ammunition on the side of the runway of the airport, confirming the news that the Nightingale was a stealth bomber.

The longer it is used, the more satisfied the military is with the performance of the Nightingale.

Fourteen days ago, the military made an attempt to directly penetrate the industrial center of China, the Northeast Industrial Center, without notifying the local military district.

It wasn't until the nightingale flew to the Changbaishan Air Base in the northeast and turned on the communication to request a landing that the military's radar discovered the nightingale's storage.

This exercise, while making the military angry, also demanded that Cheng Fei must complete the imitation of the nightingale within half a year, and demanded that it be completely finalized within three years.

It was under this premise that the Nightingale was rushed out, but the result was very disappointing, and the prototype produced could not even reach one-third of the performance of the Nightingale.

"The first way is to ask for support from above, large S-class equipment!"

Chen Tian frowned, understood what the concept of large S-class equipment was, that kind of equipment, there are only three in the country, two of which serve the navy, one to make a new generation of China-class aircraft carriers, and the other to contribute to the manufacture of nuclear submarines in China, these two are simply impossible to call out, compared to the Nightingale, aircraft carriers and nuclear submarines are more important, the Nightingale can only be said to be a strategic force to renew China, not a necessary need, but aircraft carriers and nuclear submarines are related to national defense affairs. It is impossible to interrupt for any reason.

In addition to these two, the rest of them are there, and even Chen Tian is not qualified to know, so to speak, the first method can be directly treated as nonsense!
