A big country of aerospace with black technology

"Have you heard?"

A man in a dark green army coat asked his friend who was sitting at the breakfast stand drinking wonton soup with a wretched face.

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

"What did you hear?"

As for Zhang Xingyang, who was still ordering, he glanced at the somewhat nervous man, and ordered a basket of soup dumplings and a bowl of spicy soup for himself.

After ordering, Zhang Xingyang, who sat down on a table with an empty seat, still felt a little bored.

Mobile phones these days don't have any entertainment functions.

Even a Tetris, that's fine!

When Zhang Xingyang was thinking wildly 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 low, Zhang Xingyang's hearing was unstoppable.

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

Zhang Xingyang originally thought that the other party could tell something, a big secret that would shock the world and weep ghosts and gods.

Unexpectedly, it was 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-10s produced by Chengfei is not three or four hundred, but two hundred.

Although it has been circulated in China, the situation of military equipment is "produce one generation, develop one generation, pre-research one generation, and explore one generation".

But from the actual situation, the generation difference between generations of fighter jets 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 generation division of fighter jets is the old standard, that is, the Russian standard, and now the standard will automatically add one generation.)

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

"How did you know about this?" The man sitting opposite the man in the military coat was obviously very surprised.

"hey-hey!"

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

"I was guarding the airport the day before yesterday, and finally saw a different fighter jet."

Zhang Xingyang was not very surprised by this either. After all, Chengfei produced more than 200 fighter jets, some of which were equipped in the aviation regiment near Shengjing.

Especially from the research and development unit of WS-10 engine, Shengjing Aero Engine Research Institute is very close.

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

This also led to those who are interested in hiding in a corner near the airport, sooner or later they will be able to see the scene of J-10 taking off.

In addition, the military is actually planning to release information about the self-developed third-generation aircraft little by little.

So things like this are not managed too strictly.

"What's different? Aren't airplanes all two wings? Could it be that it has four?!"

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

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

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

The man in the army coat became excited instantly, and Zhang Xingyang could clearly see the saliva from his mouth spraying across his face.

"That fighter jet does have four wings!"

"There are two little wings in front of the wing!"

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

"You mean, duck wings?!"

The man on the opposite side didn't care too much about the man in the military coat spraying his saliva on his face, but asked with some doubts:

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

"Don't you think the Su-27 is a new fighter?"

The description of a man in a military overcoat makes it hard not to remind people of the Su-27 fighter jet our family imported from Damao’s.

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

But in fact, the Su-27 fighter jets and Su-30 fighter jets introduced in China are not designed with canards.

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

Especially on the basis that the official has not released accurate information, everyone can only obtain information from various magazines, and the information obtained is not very accurate.

"impossible!"

The man in the army coat also became a little excited at this time:

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

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

"I'm sure I read that right!"

The man on the opposite side was also lost in thought at this time. After all, there are actually not many single-engine fighters with canard wings in the world at this time.

All he could think of was the "Gripen" fighter jet that had been hyped so much at this time.

However, if the country wants to obtain the "Gripen" fighter jet, it should be unlikely.

"Do you think this is a fighter jet developed by our family?"

The man in the military overcoat looked at the silent man across from him and asked.

"I do not know."

The man on the other side didn't have any intention of having breakfast at this time.

"By the way, where did you see it, can you show me?"

"It's at the Chengnan Airport, but there are two guard posts, so it's not easy to get close."

The man in the army coat was also very happy to hear that the man on the other side wanted to go there with him.

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

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

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

"You ask the airport to check carefully."

The improvement work of WS-10 has basically reached the final stage, and the potential of this engine is basically exhausted.

Zhang Zhengjiang has basically been soaking in the military airport during the recent period, 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. It is much more convenient for him to contact the airport than himself.

Zhang Xingyang's main reason for coming to Shengjing this time is to see how far WS-10 has reached the final stage of development.

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

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

This is also the reason why the new generation of engines is about to start project development.

The wontons at the breakfast shop tasted so delicious that Zhang Xingyang even hiccupped after the phone call.

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

Because this time he needed to go to the military airport, Zhang Xingyang was not allowed to take a taxi there by himself.

"Professor Zhang, you look quite young."

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

As for why Zhang Xingyang was called Professor Zhang, it was mainly to hide his identity from 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 provided Zhang Xingyang with several security personnel hiding beside him.

In case of various dangers that may arise, especially assassinations from abroad.

Zhang Xingyang's current identity on the surface is a newly promoted professor of aerodynamics at the University of Aeronautics and Astronautics.

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

The process of riding in the car was quite boring, Zhang Xingyang still had some leisure time to make some jokes with the young man.

"Actually I'm in my forties."

There is nothing wrong with this sentence, if his two lifetimes add up, he would be almost fifty years old.

"Ho!"

While driving the car skillfully, the young man took another look at Zhang Xingyang's face, which seemed to be in his twenties.

"Then you look young."

"If you didn't tell me, I would have thought you were about my age."

"Hahaha"

Zhang Xingyang also laughed at this time.

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

The driver was also a little surprised at this time:

"Then you are only in your twenties!"

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

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

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

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

"Master Zhang, please excuse me."

"It's such a cold day, you still come out to pick me up."

Zhang Xingyang walked forward with some embarrassment, shook hands with Zhang Zhengjiang and said.

"This temperature is nothing."

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

"If you come in another two months, it will be the coldest time!"

As a person who lived in a constant temperature space base city in his previous life and basically lived in the southern tropics and subtropics in this life, Zhang Xingyang has experienced the cold a few times.

Almost all of them were felt in Shengjing.

This is truly an unforgettable city!

"Master Zhang, how is WS-10 improving now?"

Zhang Xingyang and Zhang Zhengjiang walked side by side, ready to go to the maintenance center to check the condition of the latest WS-10.

In fact, the WS-10 at this time is almost different from the WS-10 that Zhang Xingyang saw for the first time more than two years ago.

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

But Zhang Xingyang is still more used to calling him by his original name.

It's as if the most affectionate name parents call is actually the child's baby name.

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

Zhang Zhengjiang still proudly introduced 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. After consuming 1,000 kg of fuel, it will weigh 11,400 kg. The altitude is 11 kilometers. When the Mach number is 1, the lift-to-drag ratio of the J-10 is 4, and the maximum thrust of the engine without afterburner is required. It is 2.85 tons.

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

There is a great possibility to achieve supersonic cruise!

"Supersonic cruise achieved?!"

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

"In our latest flight experiment, without afterburner, the J-10 successfully completed 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, before the F22 was officially born, supersonic cruise was almost impossible for fighter jets from various countries.

Most fighter jets can only fly at supersonic speeds for a short period of time with afterburner turned on.

Although Zhang Xingyang also guessed that the flight experiment Zhang Zhengjiang mentioned was most likely carried out without loading missiles.

But in this era, even without missiles, fighter jets capable of supersonic cruise basically do not exist.

"Such a result is probably the limit of this engine." Zhang Xingyang said rationally.

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

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

Zhang Zhengjiang is still very humble, knowing that WS-10S can achieve such excellent performance, largely due to the technical support provided by Zhang Xingyang and his Rocket Research Institute in terms of materials and metal processing.

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

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

The first thing that catches the eye is a J-10 that has undergone large-scale magic modification, and several WS-10S engines that have been almost dismantled into parts.

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

Especially the wings and vertical fins made of original carbon fiber and carbon-carbon composite materials that have not been coated.

Zhang Xingyang could tell at a glance that this was the latest product from Factory 703.

Large-sized carbon fiber materials can not only improve the strength of fighter wings, but most importantly, reduce the weight of fighters.

This is also an important reason why J-10 can perform supersonic cruise after applying WS-10S!

"Master Zhang, have you started to study the vector nozzle problem of the engine?"

Looking at the pieces of jagged composite material on the ground that are obviously different from the traditional engine exhaust nozzles, Zhang Xingyang said with some doubts.

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

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

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

"We have made some attempts on the vector nozzle."

"However, nothing has been done so far."

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

Zhang Xingyang said in a daze, "Are we still making third-generation machines?"

"This level seems to be below the level of the fourth-generation machine, right?"

After Zhang Zhengjiang thought for a while, he said:

"Perhaps it can be called three and a half generations?!"

At this time, Zhang Xingyang thought of a stalk in the future, smiled and said:

"We don't have any fourth-generation aircraft, we are just changing the J-10!"
