The military-industrial scientific research system of the academic master.

Chang Haonan's original intention was to go directly to Institute 601.

After all, Factory 112 is only responsible for production, and structural improvement is left to the research institute.

However, Yao Mengna directly changed direction and took Chang Haonan to a small door next to the assembly workshop.

"While we were producing the first batch of two aircraft, we also assembled an additional complete airframe to conduct some aerodynamic, structural and flight control tests for the comrades of the 601 Institute, in order to facilitate the docking with the production process. , so it was placed in the test workshop next door.”

He Ming explained as he walked.

Now Chang Haonan finally understood why he met Yao Mengna here by such a coincidence.

The latter should theoretically be hung at the research institute.

After walking in the corridor for a few minutes, He Ming opened an inconspicuous door.

Inside is a space slightly smaller than the previous assembly workshop.

"This was specially renovated from an old workshop for Project No. 11."

After the three of them walked in one after another, He Ming closed the door with his backhand and introduced at the same time:

"Originally, this place was planned to be used to produce the J-7 after surveying and mapping. Later, because the entire project was moved to the south, it has been idle. Later, it was used as a final assembly workshop for the J-8 for a period of time."

"But because the overall design is too old, it is difficult to adapt to the production needs of new models. The previous plan was to dismantle and rebuild it as the second workshop of the J-8C. Later, I thought it happened to be close to the J-11 assembly line, so I used it to build it. Tested.”

While he was talking, a plane suspended in mid-air appeared in front of Chang Haonan.

To be precise, it is the shell of an airplane.

Because even if the distance is not close, you can still see that places like radars and engines are all equipped with counterweights.

Moreover, the skin color on the surface of the aircraft has also been changed from yellow to a slightly green color.

"It seems that you have put a lot of effort into this improvement plan..."

Under normal circumstances, it is not necessary to conduct such structural testing simply by introducing a final assembly line.

For example, in India, the static test of Su-30MKI was completed in Russia.

At least there's no need to do it so early.

For example, the static test of the J-6 was completed when preparing to build the J-6.

Because the final steps of this kind of test are to destroy one or more complete aircraft, they are very valuable combat resources for the Chinese Air Force, which currently seriously lacks immediate combat capabilities.

In the previous generation, the J-11's static verification machine was put into use only after entering the new century.

But now, the action is obviously much earlier.

"According to the path of 'production while improvement' we have set, the first three batches of six aircraft, except for the wingtip pylons, are no different from the Su-27SK aircraft we imported before,"

He Ming explained from the side:

"The 24 single-seat aircraft from the fourth to sixth batches, and the first batch of four two-seat aircraft, will begin to use the upgraded new body that Yao Gong just said, and the performance will be slightly better. The most important thing is that it has The N4M radar in surface-to-sea mode has limited surface-to-sea strike capabilities."

"Is it equivalent to the Su-27SM and Su-30 from the original factory in Komsomolsk?"

Chang Haonan turned around and confirmed.

The basic model of the Su-27 does not have any ground attack capabilities except rockets and iron bombs. In fact, it is a complete waste of the huge bomb load brought by the Flanker.

The J-10 does have multi-purpose capabilities, but its size still severely limits its performance.

And if a true multi-purpose fighter can be obtained a few years in advance, it will be a huge benefit to the Air Force's combat effectiveness upgrade and tactical transformation.

Of course, the price is that the number of JH-7s definitely does not need to be that many.

But it's also a good thing. Hojing already specializes in large aircraft, so it would be too wasteful to use the production line to build fighter-bombers.

"Yes, there are a total of 34 aircraft in these six batches, which is also the entire quantity we produce using 100% Russian components. Later, we will gradually adopt serial assembly production, and gradually transition to completely domestic production except for the power system."

Project No. 11 is a contract between China Aviation Industry and Sukhoi and has nothing to do with Rulika-Saturn, which built the engine.

But when it came to this, He Ming paused for a while, and then added:

"Of course, after Mr. Chang's turbofan 10 is completed, even the power system will be solved. By then, the third-generation fighter jet will be fully domestically produced..."

"You just said that in addition to the power system, small things such as aircraft fasteners can also be localized?"

Chang Haonan noticed some details mentioned by the other party.

In the aviation manufacturing industry, high technology may be hidden in every detail.

Aircraft fasteners are inconspicuous little things like bolts and rivets used on airplanes.

But it is inconspicuous, but its technical content is not low.

Moreover, there are many types of fasteners used on an aircraft, and the specific performance requirements and materials used are very different.

In addition, there are no shortcuts in materials and process issues, resulting in very slow development.

In the previous life, even until about 2020, China imported a large number of aircraft fasteners for production every year.

"can."

He Ming, who had never experienced any of this, nodded naturally:

"These are all part of the technology sharing clauses in the contract. Correspondingly, many Russian technologies that were previously on paper will also use our resources, mainly computer resources, for further development."

While chatting with He Ming about the progress of Project 11, Chang Haonan briefly greeted several researchers along the way and walked quickly to the plane.

Then he raised his head and looked carefully at some details on the plane.

Although not much can be seen clearly, one can clearly see a set of bolts on the innermost side of the wing, as well as the corresponding electrical interfaces.

Moreover, it is also a two-seater model.

In other words, it is even a real Su-30 airframe after the first round of upgrades.

In the last generation, China did not introduce and produce the two-seat Su-27UBK or Su-30. The J-11BS, including the subsequent J-16, were all independently developed models based on the J-11B.

Although Project 1997 on this timeline is completely different from its previous life, Chang Haonan was still a little shocked when a complete version of the Su-30 was built in .

You know, all the "Su-30" used for flight performances in the early years, even the first batch of Su-30MK exported to India, were actually directly painted with Su-27UB...

"Is my influence already so terrifying?"

Although Chang Haonan secretly felt that this matter had something to do with him, he was still a little surprised by the progress.

You know, after the J-8C was successfully finalized, Chang Haonan returned to Shengjing several times for the turbofan 10 matter. Before that, he had not directly intervened in Project .

If such a project can have such a huge change because of him, it will undoubtedly mean that it is one step closer to the goal at the beginning of the rebirth.

"Is this body the two-seater model we are going to assemble?"

"Yes."

He Ming nodded:

"It was brought extra from Komsomolsk for research. It is also a typical example of the implementation of the Russian technology that was only on paper as I just mentioned."

"We plan to call the aircraft in this technical state the J-11A for the single-seat model and the J-11AS for the two-seat model. Starting from the seventh batch of aircraft, the aircraft's structure and avionics equipment will be further upgraded."

"This airframe is prepared for the second round of improvement plan. First, it is to eliminate the structural weak area of ​​the central lift body. Second, it is to upgrade a larger proportion of composite materials and lithium aluminum alloy to reduce weight. Third, it is to completely replace it with domestically produced ones. modernized airborne equipment and fully compatible with domestic ammunition systems."

Just when He Ming was introducing this, Yao Mengna, who had just walked around to the other side of the plane, came back holding a laptop in each hand:

"Mr. Chang, I brought the software's operation log and results."
