"Well, nice to meet you, too, but I don't know what to call ...... yet"

Although the other party's tone and expression were very kind, Xu Yang still felt some inexplicable coldness around him.

"It may be that I am used to the weather in Jinling during this time, and the temperature here in Hojing is a little low, so it seems that I will have to add a piece of clothing tomorrow......"

She had to tell herself this in her heart.

"Yao Mengna, you are Chang Haonan's senior sister, when we worked in Shengjing before, I heard him mention you, so I have always wanted to see the ability of my predecessors."

Yao Mengna still maintained the proper smile she had just now when she introduced herself.

"It doesn't hurt to see it, but this ...... Dr. Yao, I don't think we're in charge of the same project......"

Xu Yang was keenly aware that the other party was a little shallow hostile to him, and although he didn't know where it came from, he still gave a silent response almost intuitively.

The main thing is that the title of senior sounds a little harsh inexplicably.

She is obviously not yet 30 years old, so it sounds like she is in her seventies and eighties......

Chang Haonan, who was standing on the side, only felt that these two were a little familiar at first, but when he looked at it, he found that the atmosphere didn't seem to be right.

As for what was wrong, he couldn't say anything for a while.

But he instinctively thought something should be done:

"Speaking of which, why don't we get in the car first? After all, there are still test tasks to be done tomorrow......"

Chang Haonan originally wanted to say that he had to go to his residence early to rest today, but Yao Mengna took it directly;

"Senior brother, do you want to take a look at our modification progress?"

If it rests on other people, it will definitely be necessary to eat, but Yao Mengna knows Chang Haonan's character.

When the task is in place, I am afraid that inviting him to dinner will be pushed off nine times out of ten.

But asking him to go to the final assembly workshop to see the plane will definitely not.

"Modification progress?"

Chang Haonan's reaction was not at all what Yao Mengna expected:

"It's only been a little over three weeks since I left Ho Kyo, and you've all started to modify?"

This is actually a bit of a double standard.

After all, he himself has done similar efficiency more than once.

But now that I hear others say this, it's really a bit outrageous when I think about it.

That's fast......

"This speed is really good compared to usual, but it's still a lot worse than you...... junior brother."

Yao Mengna opened the car door as she spoke, motioning for Chang Haonan to sit in.

Then he sat in the back row.

This frees up the co-pilot.

Unlike the general scene, where the boss is in the right back seat, powerful institutions such as the military generally regard the co-pilot as the main seat, because the officer who takes the car out will usually sit here.

Xu Yang seemed to know the difference, so he hesitated for a moment, and finally knocked on the car window.

"I'll go to the guest house with them first, and I'll see you tomorrow when I test."

In fact, so far she's only enjoying the smoothness of working with a genius.

Although I am also very interested in the aircraft in Yao Mengna's mouth, after all, it is not my professional scope, and I can really only take a look at it when I go, so it is better to take a good rest and leave enough energy to deal with tomorrow's test task.

After a brief farewell, Chang Haonan and Yao Mengna's car quickly separated from the others and drove in the direction of the assembly workshop of Factory 172.

Soon, the brightly lit factory building came into view, and two huge fighter-bombers were quietly parked inside.

J-7 is actually a very huge aircraft, the volume is almost the same as the Su-27, compared to the same side of the air intake tract twin-engine single vertical tail J-8C length is close, but the whole shape appears more solid and powerful, especially the left and right two unusually thick outer figure rocker type landing gear, compared with the latter installed under the wing straight pillar landing gear will be a little more murderous.

It's just that the current two planes really don't show much murderous spirit-

One of them has been almost completely disassembled, leaving only a basic airframe, and the other, although more complete, has a number of key parts such as wings that have not yet been installed.

Chang Haonan could see almost at a glance that the progress of the aircraft behind it was actually faster, because it was already very different from the J-7 that was mass-produced before.

"Have you changed the air refueling capability for the J-7?"

He asked, looking at an aerial refueling tube in front of the right side of the nose.

"Yes, although the current range is already good, the lift-to-drag ratio of this airframe is still not very good, and users report that the range shrinkage will be more serious in the case of combat loading."

Yao Mengna explained while getting out of the car with Chang Haonan, and then slammed the door shut:

"Although we don't have a few tanker planes in total now, after discussing with Mr. Tang, I still decided to leave a memory for the troops."

Obviously, at least during this time, she can already be a stand-alone existence and talk and laugh directly with the chief model engineer.

The two walked into the assembly workshop one after the other.

As the distance from the plane narrowed, Chang Haonan quickly saw more details

The current installation method of this fuel filling pipe is relatively simple, similar to the 9-17 MiG 29SMT, where a foldable fuel filling pipe sleeve is installed directly on the outside of the original skin, forming a more obvious bulge, rather than the more common design that can be completely retracted into the nose.

However, it is definitely better than a fixed fuel filling pipe.

What's more, there was no such thing in the timeline before his rebirth, and the J-7 never had the ability to receive oil in the air from beginning to end.

And Chang Haonan has never even seen the J-7 after being reborn, nor has he talked about things like improvement plans.

This means that Huaxia's aircraft upgrade project has changed from its previous life without his direct intervention.

It also means that he has not tossed in vain for most of the past six months.

It has indeed led to the development of a large number of engineering and technical personnel.

In addition, the integrated windshield that could only be seen on the J-7A also appeared in advance, replacing the original three-piece windshield with poor vision, considering that Yao Mengna had already done a similar job during the 83 project, so it should indeed be very proficient.

"Are there any other improvements besides the tubing and canopy?"

The degree of completion of these two planes is really not high, and Chang Haonan can't see more clues.

"Of course, at present, it is preparing to upgrade the original 232H radar, enhance the anti-jamming ability, and add a continuous wave irradiator, the J-7 is now the second best in the hands of the Navy after the two J-8C, how can it be able to play semi-active bombs......"

"In addition, the two aircraft will be upgraded with the 1553B bus and distributed weapons management system, as well as the monochrome LCD display in the cockpit will be replaced with a color one."

For the first time, Yao Mengna felt that she had endless things to say in front of Chang Haonan, and she no longer had to be an audience almost unilaterally as she did in the past.

And Chang Haonan next to him was already attracted by this last sentence.

Having a data bus means that the payload capacity of the aircraft can be easily upgraded to become a qualified multi-functional air tactical platform.

And the compact version of the electronic jamming pod they are about to test will need exactly one such platform in the future.

"So this is the template for the new J-7?"

Chang Haonan raised his hand and patted it lightly on the antenna of the 232H radar.

"Of course not, after the turbofan 9 can be mass-produced, the new J-7A will have more upgrades, including a new model of radar, four-redundancy flight control system and the like, now it is just on the basis of the original, to make a technical verification for the improved model, if there is no problem, the follow-up may gradually upgrade the old aircraft to this standard during the repair."

Yao Mengna replied.

"So now these two can't be called J-7A?"

"Yes, if you have to have a different name, then referring to the habits of foreign armies, it can be called J-7MLU, Mid-Life Upgrade, mid-life upgrade."
