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

The progress of the J-11B on this timeline can be said to be very smooth.

In May 1999, exactly half a year ago, Chang Haonan's heavy-duty die forging press research team forged the first domestic bulkhead for the new J-5B airframe during the trial production process as a gift for the National Day.

In the following three months, various parts of the two prototypes 01 and 02 were produced, including two batch 00 (trial production batch) turbofans 10A delivered in mass production standards, and the new turbofan 14A provided by Dianke 1493 112 radars were all sent to the Factory one after another.

The original plan of the factory was to try to get the aircraft off the assembly line before National Day, and also to present a 50th anniversary gift.

But after all, the J-11B uses a lot of new processes and technologies. Considering that the time is a bit tight, in order to ensure that nothing goes wrong and avoid haste, waste of speed, in the end we did not meet the deadline for this matter.

Therefore, the offline date will miss the National Day.

Of course, the gift banners and internal promotional materials were still produced, but the array was obviously not as good as those projects that were rushed before the National Day.

After more than a month of ground testing, and after confirming that all subsystems can operate normally on the ground, the first flight was launched.

Chang Haonan took the Challenger 601 as usual and returned to Shengjing, where he had left for almost half a year.

Only this time, when the plane was circling and descending, Chang Haonan saw a yellow-skinned and black-headed fighter jet parked in front of the No. 2 assembly workshop——

Under his influence, the J-11B on this timeline is now more obviously different from the old model, but the difference is still not something that can be seen at a glance from a distance.

The reason why Chang Haonan was so sure was that there was an unusually large group of people surrounding the plane.

In most cases, this is a treatment only given to first-flying prototypes.

After a tight U-turn, Chang Haonan's plane landed on the familiar yet unfamiliar runway of Beiling Airport.

"Mr. Chang, welcome to our factory for guidance!"

He Ming, who came up, shook hands with Chang Haonan and said half seriously and half jokingly.

Chang Haonan's previous positions have been the general manager of Torch Group and the chief designer of the Turbofan 10 project. The former is equivalent to a second-level sub-unit under the central enterprise, on the same level as Factory 112, not to mention the Turbofan 10, even after passing Upgrading is no longer considered a subsystem of the aircraft, but is only equivalent to Project .

So at that time, it was equivalent to brother units coming over to cooperate.

However, Chang Haonan was further promoted later, and the Aviation Power Group was already on par with the Aviation Industry Group. Now when we come to Factory 112, although there is no direct affiliation between the two, there is no problem in saying that we are here.

Of course, He Ming was an old acquaintance of Chang Haonan who had worked with Chang Haonan since the August 3rd Project. If he really followed the standards for receiving superiors, it would make the atmosphere very tense.

Chang Haonan's trip was to follow the working conditions of these two turbofan 10A machines in mass production. Naturally, it is impossible to talk about these pomps:

"Mr. He was joking. This time, as the chief designer of the Turbofan 10, I came here to coordinate the first flight of the J-11B, so I can just do the same as before."

While chatting with the other party, Chang Haonan's eyes were already focused on the assembly workshop in the distance.

Before he was reborn, he also had a lot of dealings with the J-11B.

It's just that it's all indirect.

For example, testing certain batches of small changes.

In fact, when the previous J-11B entered service in 2009, it was already slightly behind the times. After all, the mainstream international fighter models at that time had basically completed the transition from the standard third generation to the third and a half generations.

However, for China, the J-10B that has used the turbofan 11 engine since the second batch has truly entered the "third-generation aircraft freedom". Combined with sufficient range and bomb load, it finally allows the Air Force to deal with incoming attacks with ease. Sea and air pressure in several directions.

It was also roughly from that time that the number of times certain old opponents denounced "unprofessional interceptions" skyrocketed, and the masses were finally able to see their own fighters in the news frequently.

Therefore, although the technical demonstrator of the J-20 was unveiled in 2011, taking away most of the attention, due to the production capacity of the third-and-a-half-generation and fourth-generation fighters, the J-11B will be classified as a fighter jet until 2020. The absolute main model.

Now, Chang Haonan has advanced this time by a full ten years.

Even he himself was a little curious about what kind of chain reaction it would trigger.

The apron area of ​​Beiling Airport is not large, and there is no need for a shuttle bus. The group of people walked towards the factory.

In addition to the employees of Factory 112, Chang Haonan also saw several technicians from Liming at the scene——

This is normal. When a new phone is launched, a technical team must be in place to ensure it.

Compared with the previous generation, the most obvious difference in the appearance of today's J-11B is the addition of a pair of 2000kg heavy-load hardpoints under the inner side of the wings, as well as the addition of an aerial refueling device.

With the arrival of several IL-78s and IL-78Ms, the Chinese Air Force finally has a relatively stable aerial refueling capability.

Although the range of more than 4000 kilometers after the replacement is basically enough, the more of this kind of thing is always better.

"Speaking of which, Mr. He, how is the progress of prototype 02?"

On the way, Chang Haonan suddenly asked He Ming next to him.

Parked at the door of the workshop is the 01 aircraft that is preparing for its first flight. According to custom, the 02 aircraft is a static verification machine with no equipment and only a counterweight.

Only after completing all, or at least most of the static tests, can the aircraft be allowed to perform relatively violent high-G maneuvers.

This is also the part that Chang Haonan is most concerned about——

Installing the turbofan 10 on the aircraft and flying smoothly has been carried out on two J-11WS verification aircraft for a total of thousands of hours. There is nothing to worry about.

However, the J-11B has a brand new body, which is fixed in a different way with the engine. The new body also brings more extreme mobility and agility, so the focus is on examining the working conditions under harsh working conditions.

"It's already built."

He Ming’s answer was concise and concise:

"When we started construction, we considered that the J-11B is an aircraft that only has changes in structural design, but the aerodynamic design is basically the same. The test flight process must be completely different from that of ordinary models, so we used two aircraft at the same time. Final assembly plan.”

"Or rather, because Unit 02 does not need to install equipment, it even went offline a few days earlier than Unit 01."

This is definitely an unexpected surprise.

As He Ming just said, most improved aircraft have aerodynamic adjustments but little structural changes. He was previously worried that static verification would be delayed.

"The static test..."

Chang Haonan's tone was a little urgent.

"It's basically done."

He Ming was also an aviation veteran, so of course he knew what Chang Haonan was concerned about, and pointed in the direction of the workshop door.

"So, the first time the J-11B took to the skies, it was a full-state prototype, and it had already obtained permission to fly in complex operating conditions."

While talking, the group of people had already reached the vicinity of prototype No. 01.

As usual, several main types of training bombs or counterweight bombs will be carried during test flights.

As for the J-11B specifically...

Two Thunderbolt 12s hanging in the middle of the wing.

"The 612 Research Institute has determined the aerodynamic shape design of the new active ammunition. Although the live ammunition has not been tested yet, they have already sent the sample ammunition."

He Ming explained.

Thunderbolt 12 is no different from what Chang Haonan saw in his last life.

If nothing else, it will form the main air-to-air bomb lineup of the Chinese Air Force together with the PL8 and PL11 for a long time to come.

After walking closer, Chang Haonan suddenly discovered that there were actually two huge ammunition mounted in series in the middle of the air intake that he couldn't see just now.

Chang Haonan quickly stepped forward and patted the missile's radome, but soon saw the Russian letters on the surface:

"Oh...it should be R33."

The appearance of the two models is exactly the same, so it is not wrong to use a batch of training bombs previously prepared for the Persian F14.

Thinking about the scene where the other party was eating hot pot and singing, and was suddenly empowered by a huge thunderbolt 200 flying over 13 kilometers away, Chang Haonan couldn't help but reveal a slightly evil smile...
