"Did you hear that?"

A man in a dark green military coat asked his friend who was sitting at a breakfast stall drinking wonton soup with a lewd face.

The man's friend obviously didn't know what the man wanted to ask, and stared blankly at each other while eating wontons:

"What did you hear?"

As for Zhang Xingyang, who was still ordering food on the side, he glanced at the man who was a little nervous, and ordered himself a cage of soup dumplings and a bowl of spicy soup.

After ordering, Zhang Xingyang, who sat down at a table where there was still a vacant seat, still felt a little bored.

In these years, mobile phones do not have any entertainment functions.

Even if it's a Tetris, that's fine!

Zhang Xingyang was thinking crankily in his heart.

"Our third-generation aircraft, I heard that it has already made its first flight!"

The man in the military coat whispered in his friend's ear at this time.

Although the other party's voice was very small, it couldn't stand Zhang Xingyang's ears and his hearing was very good.

I still heard what the man in the military coat said.

Zhang Xingyang originally thought that the other party could say something, shocking the world, crying ghosts and gods' big secrets.

I didn't expect it to be just news about the first flight of the J-10.

And that was almost two or three years ago!

Now that the mass-produced models of the J-10 have come out, the number of J-10 produced by Chengfei is not three or four hundred, but there are two hundred.

Although it has been circulated in China that the situation of military equipment is "one generation of production, one generation of development, one generation of pre-research, and one generation of exploration".

But in practical terms, the generational difference between generations of fighters is not as the outside world thinks.

When the third-generation aircraft came out, the fourth-generation aircraft was already under development, the fifth-generation aircraft was already in pre-research, and the sixth-generation aircraft was already being explored.

(The above fighter generation division is the old standard, that is, the Russian standard, and now the standard is automatically added by one generation.) ）

At this time, Zhang Xingyang's xiaolongbao was also served, and while eating pork soup xiaolong, he listened to the conversation of the people at the table next to him.

"How do you know this?" The man sitting across from the man in the military coat was obviously surprised.

"Hey, hey!"

The man in the military coat smiled a little proudly at this time and said:

"The day before yesterday, I was on the edge of the airport for a day, and I finally saw a fighter plane with a difference."

Zhang Xingyang was not very surprised by this, after all, there were more than 200 fighters produced by Chengfei, and some of them were also equipped in the aviation regiment near Shengjing.

In particular, it is very close to the research and development unit of the WS-10 engine, Shengjing Aero Engine Research Institute.

From time to time, it is necessary to cooperate with the WS-10 improvement test work of the Engine Research Institute, and the attendance rate of their J-10 fighters is very high.

This also leads to the fact that as long as people hide in a corner near the airport, sooner or later they will be able to see the scene of Jian-10 taking off.

In addition, in fact, the military is planning to disclose its information little by little about its self-developed third-generation aircraft.

So such things are not managed too strictly.

"What's different, the plane doesn't all have two wings, is it possible that it has four?!"

The man drinking the wonton soup obviously didn't believe the words of the man in the military coat opposite.

After all, at this time, the main domestic fighter is either J-7 or J-8.

"Don't say it, it's true!"

The man in the military coat instantly became excited, and Zhang Xingyang could clearly see the saliva in his mouth spraying on the other side.

"That fighter does have four wings!"

"There are also two small wings in front of the wing!"

Obviously, although the man in the military coat is very strong in action, his theoretical knowledge is not very rich.

"You mean, canard wings?!"

The man on the other side didn't pay much attention to the behavior of the military coat man spraying spit on his face, but asked with some confusion:

"Isn't that the special technology on the old Maozi fighter in the north?"

"Don't think of the Su-27 as a new fighter, right?"

The description of the man in the military coat is hard not to think of the Su-27 fighter jet that our family introduced from Da Mao's family.

After all, in today's fighter world, fighters with canard wing designs are basically the only ones.

However, in fact, the Su-27 fighter and Su-30 fighter jets introduced in China are not designed with canard wings.

Of course, these details are difficult for ordinary people who are not professionals to distinguish.

In particular, on the basis of the lack of accurate official information, everyone can only get information from various magazines, and the information obtained is not accurate.

"Impossible!"

The man in the military coat was also a little excited at this time:

"That's definitely not Mao's Su-27!"

"The Su-27 is a twin-engine fighter, and that plane is a single-engine fighter!"

"I'm not mistaken!"

The man on the other side was also in thought at this time, after all, there were actually few single-engine, canard-wing fighters in the world at this time.

All he could imagine was the "Gripen" fighter that was blown very loudly at this time.

However, if China wants to obtain the "Gripen" fighter, it should not be very likely.

"Do you think this is our own fighter?"

The man in the military coat looked at the man who had fallen silent across from him and asked.

"I don't know."

The man opposite didn't have the heart to eat breakfast at this time.

"Anyway, where did you see it, can you show me?"

"It's right there at Seongnam Airport, but there are two sentry posts, so it's not easy to get close."

The man in the military coat was also very happy to hear that the man opposite wanted to go with him.

Zhang Xingyang, who was still calmly drinking wonton soup, also raised his head to look at the two people sitting next to him at this time.

After the two men left, they walked out of the breakfast shop and made a phone call:

"Chief Master Zhang, I just heard that two people seem to be going to the airport to see the plane."

"You ask the airport to take a closer look."

The WS-10 is almost in its final stages of refinement, and the engine's potential is almost exhausted.

Zhang Zhengjiang has basically been immersed in the military airport recently, doing the final adaptation work for the adaptation of the WS-10 engine and the J-10.

This is also the reason why Zhang Xingyang told Zhang Zhengjiang about this matter, and it was much more convenient for him to contact the airport than himself.

The main reason why Zhang Xingyang came to Shengjing this time is to see how far the WS-10 has reached the final stage of development.

The secondary reason is to discuss with Zhang Zhengjiang the next generation of high-thrust small-bypass ratio vector turbofan engine.

The potential of the WS-10 engine, in the past two or three years, has been basically squeezed out by the Aero Engine Research Institute.

This is also the reason why the research and development of a new generation of engines is about to begin.

The wontons at the breakfast shop tasted so delicious that Zhang Xingyang had a full burp after making the call.

Soon came to pick up Zhang Xingyang's car, and it came from not far away.

Because he needed to go to the military's airport this time, he didn't let Zhang Xingyang take a taxi by himself.

"Professor Zhang, you look quite young."

The military young man who was in charge of picking up Zhang Xingyang said with a smile after looking at the reflector.

As for why Zhang Xingyang is called Professor Zhang, it is mainly to hide his identity in front of everyone.

After all, almost all the projects he is involved in now are related to national security issues.

Even the staff of the security department equipped Zhang Xingyang with a few security guards who were hiding around him.

In case of possible dangers, especially assassinations from abroad.

Zhang Xingyang's current identity is that he is a newly promoted professor of aerodynamics at the University of Astronautics.

"Hehe, in fact, I just look young."

The process of riding in the car is also quite boring, and Zhang Xingyang still has some idle thoughts to make some jokes with the young man.

"I'm actually in my forties."

There is nothing wrong with this sentence, if he has two lives combined, he will be almost fifty years old.

"Huo!"

While the young man was skillfully driving the car, he glanced at Zhang Xingyang's face, which looked like he was only in his twenties.

"Then you look young."

"If you didn't, I thought you were about the same age as me."

"Hahaha"

Zhang Xingyang also laughed at this time.

"Tease you, I'm actually two or three years older than you!"

The driver was also a little surprised at this time:

"Aren't you in your twenties!"

"It's amazing to be a professor now!"

Before the young man could continue to chat with Zhang Xingyang for a while, he had already arrived at the location of the military's airport.

After handing over the two formalities, Zhang Xingyang walked into the airport.

Before he walked into the engine maintenance center, he saw Zhang Zhengjiang waiting for him at the door:

"Chief Master Zhang, I'm sorry for you."

"On such a cold day, you came out to pick me up."

Zhang Xingyang stepped forward a little embarrassed, shook hands with Zhang Zhengjiang and said.

"That's not much of a temperature."

Zhang Zhengjiang, who has lived in Shengjing for many years, smiled and said:

"If you come in two months, that's the coldest time!"

As a person who lived in the constant temperature space base city in his previous life and basically lived in the tropical and subtropical regions of the south in this life, Zhang Xingyang has experienced the cold a few times.

Almost all of them were felt in Shengjing.

It's an unforgettable city!

"Mr. Zhang, how is the WS-10 improving now?"

Zhang Xingyang and Zhang Zhengjiang walked side by side, ready to go to the maintenance center to take a look at the latest WS-10.

In fact, the WS-10 at this time is almost not the same thing as the WS-10 that Zhang Xingyang saw for the first time more than two years ago.

In the official naming, he has also been changed to WS-10S.

However, Zhang Xingyang is still more accustomed to calling him by his original name.

It's as if the most affectionate name of a parent is actually the child's name.

"The latest model of the WS-10S has basically reached the limit of its potential in terms of performance!"

Zhang Zhengjiang is still quite proud to introduce their recent achievements:

"The biggest performance breakthrough is that the conventional thrust has finally reached 3.2 tons!"

This information somewhat attracted Zhang Xingyang's attention.

The normal take-off weight of the J-10 fighter is 12,400 kg, 11,400 kg after consuming 1,000 kg of fuel, the altitude is 11 kilometers, the lift-to-drag ratio of the J-10 is 4 when the Mach number is 1, and the maximum afterburner thrust of the required engine is 2.85 tons.

To put it simply, if the aero engine can exceed 2.85 tons without afterburner.

There is a great possibility of supersonic cruise!

"Supersonic cruise achieved?!"

This news is really important, Zhang Xingyang couldn't help but ask.

"In our latest flight experiment, without afterburner, the J-10 successfully completed the supersonic cruise at a speed of Mach 1.15!"

Zhang Zhengjiang also said very proudly.

This is indeed something to be proud of.

After all, when the F22 was not officially born, supersonic cruise was almost impossible on the fighter jets of various countries.

Most fighter jets are only able to perform short supersonic flights with afterburner turned on.

Although Zhang Xingyang also guessed that the flight experiment mentioned by Zhang Zhengjiang was most likely carried out without carrying a missile.

But in this era, even without a missile, a fighter capable of supersonic cruise can be said to be basically non-existent.

"This kind of achievement is estimated to be the limit of this engine." Zhang Xingyang still said more rationally.

"The J-10 can do this without a built-in bomb bay."

"Master Zhang, it's not easy for you!"

Zhang Zhengjiang is still very modest, knowing that the WS-10S can achieve such excellent performance, to a large extent, it is related to the technical support provided by Zhang Xingyang and his rocket research institute in materials and metal processing.

"It's not easy for everyone, and you guys have also paid a lot for the WS-10S."

Walking into the repair center, it was not as cold as outside.

The first thing that caught my eye was a J-10 that had undergone a large-scale magic change, as well as several WS-10S engines that were almost disassembled into parts.

Although the J-10 is still the same as before, many of the parts on it have been improved.

In particular, the wings and tails are made of uncoated original carbon fiber and carbon-carbon composites.

Zhang Xingyang can see at a glance that this is the latest product of Factory 703.

The large size of the carbon fiber material can not only improve the strength of the wing part of the fighter, but most importantly, it can reduce the weight of the fighter.

This is also an important reason why the J-10 is able to carry out supersonic cruise after the application of the WS-10S!

"Chief Engineer Zhang, have you started to study the vector nozzle of the engine now?"

Looking at the serrated composite pieces on the ground, which were obviously different from the traditional engine tail nozzle, Zhang Xingyang said with some doubts.

"Yes, didn't you mention the technical idea of a binary vector engine before!"

After Zhang Zhengjiang glanced at it, he recalled a little and said:

"After we found out that there was nothing to improve in terms of the performance of the WS-10S engine."

"We've made some attempts at vector vents."

"But I haven't made a name for myself yet."

Looking at the demon in front of him, even the J-10 designers in his previous life may not dare to admit it after seeing it.

Zhang Xingyang said with some distraction: "Are we still doing a third-generation aircraft?" ”

"It doesn't seem to be up to the fourth generation aircraft at this level, right?"

Zhang Zhengjiang thought for a while and said:

"Maybe it's three and a half generations?!"

Zhang Xingyang remembered a stalk in the future at this time, smiled and said:

"How can we have any fourth-generation aircraft, we are just J-10!"
