Chapter 490 Progress of Project No. 11
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 connection with the production process, it is 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.
In theory, the latter should 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 assembly workshop just now.
"This is what we renovated from an old workshop for Project No. 11."
After the three of them walked in, He Ming closed the door with his backhand and introduced at the same time:
< br>“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 served as the final assembly workshop of 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 felt that it was close to the J-11 assembly line, so I used it for testing. . ”
While he was speaking, 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 color of the skin 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, there is no need to conduct this kind of structural testing by simply introducing a final assembly line.
For example, in India, the static test of Su-30MKI was completed in Russia.
At least there is 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 life, the static verification machine of the J-11 was put into use only after entering the new century.
But now, the action is obviously much earlier.
“According to the path of ‘producing while improving’ 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 4 two-seat aircraft, will begin to adopt what Yao Gong just said. , the upgraded new body has slightly better performance. The most important thing is the N001M radar with ground-to-sea mode, which has limited ground-to-sea strike capabilities."
"Equivalent to that of Komsomolsk. The original Su 27SM and Su 30? ”
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 body.
The J-10 does have multi-purpose capabilities, but its size still severely limits its performance.
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 that we will 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 builds the engine.
But when it came to this, He Ming paused for a while, and then added:
“Of course, wait until Mr. Chang’s turbofan 10 is ready. After that, 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 to problems related to materials and processes, 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.
“Okay.”
He Ming, who has not 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."
Chang Hao While chatting with He Ming about the progress of Project 11, Nan 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 you can't see much clearly, you can clearly see a set of bolts on the innermost side under the wings, as well as the corresponding electrical interfaces.
Also, it is 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 later J-16, were all independently developed models based on the J-11B.
Although Project 11 on this timeline is completely different from its previous life, Chang Haonan was still a little shocked that a complete version of the Su-30 was built in 1997.
You must know that 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 must know that 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 11.
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.
"This body is the two-seater model we are going to assemble?"
"That's right."
He Ming nodded:
“It was brought extra from Komsomolsk for research, and it is also a typical example of implementing the Russian technology that was only on paper as I just mentioned. ”
“We plan to call the single-seat model J-11A and the two-seat model J-11AS for aircraft in this technical state. Starting from the seventh batch of aircraft, the structure and avionics equipment of the aircraft will be inspected. Carry out deeper upgrades.”
“This airframe is prepared for the second round of improvement plans. First, it is to eliminate the structural weak area of the central lifting body. Second, it is to upgrade a larger proportion of composite materials and lithium. Aluminum alloy weight reduction, Sanmo, is a comprehensive replacement of domestically produced airborne equipment, and fully compatible with domestic ammunition systems."
When He Ming introduced this, he just walked around to the other side of the aircraft. Yao Mengna came back holding a laptop in each hand:
"Mr. Chang, I brought the running log and results of the software."
