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

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

Although the other party's tone and expression were very cordial, Xu Yang still felt an inexplicable chill all over his body.

"Perhaps I have gotten used to the weather in Jinling during this period. The temperature here in Haojing is a bit low. It seems that I will need to wear more clothes tomorrow..."

She could only tell herself this in her heart.

"Yao Mengna is Chang Haonan's senior sister. When we were working in Shengjing, we heard him mention you before, so I have always wanted to see the capabilities of my senior."

Yao Mengna still maintained her decent smile when introducing herself.

"It wouldn't hurt to meet him, but this...Dr. Yao doesn't seem to be in charge of the same project as us..."

Xu Yang was keenly aware that the other party had a slight hostility towards him. Although he didn't know where it came from, he still gave him a calm reply almost relying on his intuition.

The main reason is that the title "senior" sounds a bit harsh for no reason.

She is obviously less than 30 years old, so when she is called like this, she feels as if she is seventy or eighty...

Chang Haonan, who was standing aside, thought at first that the two of them were a bit familiar, but as he looked at them, he realized that something was not right about the atmosphere.

As for what was wrong, he couldn't tell 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, we still have testing tasks to do tomorrow..."

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

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

If it were left to other people, Jie Feng Washing would definitely have to eat, but Yao Mengna knew Chang Haonan's character.

When you are on a mission, you will most likely be turned down if you invite him to dinner.

But asking him to go to the assembly shop to see the aircraft would definitely not work.

"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 Haojing, right? You've already started modifying it?"

This is actually a bit of a double standard.

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

But now that I hear others say this, it is indeed a bit outrageous if I think about it carefully.

So fucking fast...

"This speed is indeed very good compared to normal, but it is still far behind compared to you, junior brother..."

Yao Mengna said as she opened the car door and motioned for Chang Haonan to sit in.

Then he followed suit and sat in the back row.

This frees up the co-pilot.

Unlike ordinary situations where the boss is in the right back seat, powerful organizations such as the military usually 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 this difference, so he hesitated and finally knocked on the car window.

"I'll go to the guest house with them first. See you during the test tomorrow."

In fact, she has only enjoyed the smoothness of working with a genius so far.

Although I am also very interested in the aircraft mentioned by Yao Mengna, after all, it is not within my professional scope. I can only take a look when I go there, so it is better to have a good rest and reserve enough energy for tomorrow's test task.

After a brief farewell, the car in which Chang Haonan and Yao Mengna were riding quickly separated from the others and drove towards the final assembly workshop of Factory 172.

Soon, a brightly lit factory building came into view, with two huge fighter-bombers parked quietly inside.

The JH-7 is actually a very huge aircraft, almost the same size as the Su-27. Compared with the J-8C, which has the same dual-engine single vertical tail with air intakes on both sides, the length is similar, but the overall appearance is more substantial and powerful, especially The two unusually thick splayed rocker landing gears on the left and right have a more murderous feel compared to the latter's straight strut landing gear installed under the wings.

It's just that the two planes now really don't show much murderous intent——

One of them has been almost completely disassembled, leaving only a basic body. Although the other one is more complete, many key parts such as wings have not yet been installed.

Chang Haonan could tell almost at a glance that the progress of the latter aircraft was actually faster, because it was already very different from the previously mass-produced JH-7.

"Have you modified the ability of the JH-7 to receive fuel in the air?"

He asked, looking at an air refueling pipe on the right front of the nose of the plane.

"Yes, although the current range is already good, the lift-to-drag ratio of this aircraft is still not very good. Users reported that the range will be severely reduced when combat mounts are installed."

While explaining, Yao Mengna got out of the car immediately after Chang Haonan, and then slammed the door shut:

"Although we don't have many tankers in total now, after discussing with Mr. Tang, we decided to leave a message to the troops."

Obviously, at least during this period of time, she has been able to take charge of herself and chat and laugh directly with the model chief engineer.

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

As the distance from the plane got closer, Chang Haonan quickly saw more details.

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

However, it is definitely better than the fixed filling pipe.

More importantly, there was no such incident in the timeline before his rebirth. The JH-7 never had the ability to receive fuel in the air from beginning to end.

Chang Haonan had never even seen the JH-7 after his rebirth, nor had he talked about improvement plans or anything like that.

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

It also means that his hard work over the past six months has not been in vain.

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

In addition, the integrated windshield that was originally seen on the JH-7A also appeared in advance, replacing the original three-piece windshield with poor visibility. Considering that during the August rd Project, Yao Mengna had already made a similar one. work, so he should indeed be very proficient.

"Besides the fuel pipe and canopy, are there any other improvements?"

The degree of completion of these two aircraft was really not high, and Chang Haonan could not see any more clues.

"Of course, we are currently planning to upgrade the original 232H radar to enhance its anti-interference capability and add a continuous wave illuminator. The JH-7 is now the only treasure in the Navy's hands that is second only to the two J-8Cs in terms of performance. Only if you can play semi-active ammunition..."

"In addition, these two aircraft will also upgrade the 1553B bus and distributed weapons management system, and replace the monochrome LCD display in the cockpit 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 almost unilateral listener like in the past.

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

The data bus means that the aircraft's mounting capabilities 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 just such a platform in the future.

"So is this the template for the new JH-7 model?"

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

"Of course not. After the Turbofan 9 can be mass-produced, the newly built J-H7A will have more upgrades, including a new model of radar, a four-redundancy flight control system, etc. Now it is just based on the original. The improved model will undergo a technical verification, and if there are no problems, the old aircraft may be gradually upgraded to this standard during mid-maintenance."

Yao Mengna replied.

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

"Yes, if there must be a different name, then referring to the habits of foreign military, it can be called JH-7MLU, Mid-Life Upgrade, mid-life upgrade."
