Chapter 790 J-11B

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

In May 1999, just half a year ago, Chang Haonan's heavy die forging press research group forged the first domestically produced bulkhead for the new J-11B fuselage during the trial production process for the National Day.

In the following three months, various parts of the two prototypes 01 and 02, including two 00 batch (trial production batch) turbofan 10A delivered with mass production standards, and the new 1493 radar provided by CETC 14, were successively delivered to Factory 112.

The original plan of the factory was to try to get the aircraft off the assembly line before the 11th, and also to have a 50th anniversary tribute.

But the J-11B uses a lot of new processes and technologies after all. Considering that the time is a bit tight, in order to ensure that there is no risk and avoid haste, the deadline was not rushed for this matter.

So the date of the assembly line will miss the National Day.

Of course, the tribute banners and internal publicity materials were still produced, but the show was obviously not as good as those projects before the National Day.

After more than a month of ground testing, after confirming that all subsystems could operate normally on the ground, the first flight was ushered in.

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

However, this time, when Chang Haonan was circling and descending in altitude, he 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 visible from a distance.

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

In most cases, this is a treatment only for the first flight prototype.

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

"Boss Chang, welcome to our factory for guidance!"

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

Previously, Chang Haonan's positions had always been the general manager of Torch Group and the chief designer of the WS-10 project. The former was equivalent to a second-level sub-unit under a central enterprise, on the same level as Factory 112, and the WS-10 was even more so. Even after the upgrade, it was no longer considered a subsystem of the aircraft, but it was only on the same level as Project 11.

So at that time, it was equivalent to a brother unit coming to cooperate.

However, Chang Haonan was further promoted later, and the Aviation Power Group was already on the same level as the Aviation Industry Corporation. Now that he came to Factory 112, although there was no direct affiliation between the two, it was no problem to say that he was here.

Of course, He Ming was an old acquaintance who had worked with Chang Haonan since the 83rd Project. If he really opened up according to the standards of receiving superiors, it would make the atmosphere very stiff.

Chang Haonan was here to track the work of the two WS-10A engines on mass-produced aircraft, so naturally he couldn't talk about these pomp and circumstance:

"Mr. He is joking. I am here as the chief designer of the WS-10 to coordinate the first flight of the J-11B, so it will be fine as before."

While greeting the other party, Chang Haonan's eyes were already cast on the assembly workshop in the distance.

Before his rebirth, he had dealt with the J-11B a lot.

But it was all indirect.

For example, testing small changes to certain batches.

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

However, for China, the J-11B that used the WS-10 engine from the second batch can be regarded as truly entering the "third-generation freedom". Combined with sufficient range and payload, the Air Force can finally cope with the sea and air pressure from several directions with ease.

It was also from that time that the number of condemnations of "unprofessional interception" by some old rivals skyrocketed, and the spectators were finally able to see their own fighter jets frequently in the news.

Therefore, although the J-20 technical verification aircraft was unveiled in 2011, which followed closely, and took away most of the attention, the J-11B was an absolute main model before 2020 due to the production capacity of the third-generation and fourth-generation fighters.

Now, Chang Haonan has brought this time point forward by a full ten years.

Even he himself was a little curious about what kind of chain reaction would be triggered.

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

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

This is also normal. When a new aircraft is launched, there must be a technical team to guarantee it.

Compared with its predecessor, the most obvious difference in appearance of today's J-11B is the addition of a pair of 2,000kg-class heavy-load hanging points on the lower inner side of the wing, as well as the addition of an aerial refueling device.

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

Although the range of more than 4,000 kilometers after the engine replacement is basically enough, the more of this kind of thing, the better.

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

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

Parked at the door of the workshop is the 01 aircraft ready for its maiden flight. According to custom, the 02 aircraft is a static verification aircraft with no equipment and only counterweights installed.

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

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

The matter of installing the turbofan 10 on the aircraft and flying it steadily has been carried out for a total of thousands of hours on the two J-11WS verification aircraft, so there is nothing to worry about.

But the J-11B has a completely new fuselage, which is fixed differently to the engine, and the new fuselage also brings more extreme maneuverability and agility, so the focus is on examining the working status under harsh working conditions.

"It's already built."

He Ming's answer was concise:

"When we started working, we considered that the J-11B is an aircraft with only some changes in structural design, but the aerodynamic design is basically completely the same. The test flight process is definitely completely different from the general model, so we adopted the plan of assembling two aircraft at the same time."

"Or rather, because the No. 02 aircraft does not need to install equipment, it will even roll off the assembly line a few days earlier than the No. 01 aircraft."

This is definitely a pleasant surprise.

As He Ming just said, most of the improved aircraft are aerodynamically adjusted but the structure does not change much. He was worried that the static verification aircraft would be a drag.

"Then the static test..."

Chang Haonan's tone was a little anxious.

"Basically completed."

He Ming is also an old aviation expert. Of course, he knows what Chang Haonan is concerned about, and points to the direction of the workshop door.

"So, the first time the J-11B went up to the sky, it was a full-state prototype, and it had already obtained permission to fly complex conditions."

As they were talking, the group had already walked to the vicinity of the No. 01 prototype.

According to convention, several training bombs or counterweight bombs of the main models will be carried during the test flight.

Specifically, on the J-11B, there are...

Two PL-12s hanging in the middle of the wing.

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

He Ming explained.

PL-12 is not much different from what Chang Haonan saw in his previous life.

If nothing unexpected happens, it will form the main air-to-air bomb lineup of the Chinese Air Force together with PL-8 and PL-11 for a long time in the future.

After getting closer, Chang Haonan suddenly found that in the middle of the air intake that he had not seen just now, there were actually two huge ammunitions mounted in series.

Chang Haonan quickly stepped forward and tapped the missile's radar dome, 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 a bad idea to use the batch of training missiles prepared for the Persian F14.

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