"Did you hear that?"
A man wearing a dark green military coat asked his friend who was sitting at the breakfast stall drinking wonton soup with a lewd look on his face.
The man’s friend obviously didn’t know yet what the man wanted to ask. He stared blankly at the other person while eating wontons:
"What did you hear?"
As for Zhang Xingyang, who was still ordering at the side, he glanced at the somewhat nervous man and ordered a bowl of soup dumplings and a bowl of spicy soup for himself.
After ordering the meal, Zhang Xingyang sat down at a table that still had room, feeling a little bored.
Mobile phones these days don’t have any entertainment functions.
Even a Tetris game would be great!
While Zhang Xingyang was thinking wildly in his mind.
"I heard that our third-generation aircraft has already made its first flight!"
The man in a military coat whispered in his friend's ear at this time.
Although the other party's voice was very quiet, Zhang Xingyang's ears couldn't stand it 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 tell some secret that would shock the world and make ghosts and gods weep.
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 are out, the number of J-10s produced by Chengdu Aircraft Manufacturing Co., Ltd. is not three or four hundred, but maybe two hundred.
Although it has been circulated in China that the situation of military equipment is "one generation for production, one generation for development, one generation for pre-research, and one generation for exploration."
But from a practical perspective, the generational difference between generations of fighter jets is not what 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 classification of fighter aircraft generations is based on the old standard, that is, the Russian standard. Now the standard automatically adds one generation.)
At this time, Zhang Xingyang's Xiao Long Bao was also brought up. While eating Xiao Long Bao filled with pork soup, he listened to the conversation of the people 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 and said:
"The day before yesterday, I spent a whole day guarding the edge of the airport, and finally saw a unique fighter jet."
Zhang Xingyang was not very surprised by this. After all, some of the more than 200 fighter jets produced by Chengdu Aircraft were equipped in the aviation regiment near Shengjing.
In particular, it is very close to the Shengjing Aviation Engine Research Institute, the research and development unit of the WS-10 engine.
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 fighter jets is very high.
This also means that as long as an interested person hides in a corner near the airport, sooner or later he will be able to see the J-10 taking off.
In addition, the military is actually planning to disclose its information bit by bit about its self-developed third-generation aircraft.
Therefore, such things are not managed too strictly.
"What's so different? Airplanes all have two wings, right? Could it be that it has four wings?!"
The man drinking wonton soup obviously didn't quite believe the words of the man in the military coat across from him.
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 military coat became excited instantly, and Zhang Xingyang could clearly see the saliva from his mouth spraying all over the other person's 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, he does not have very rich theoretical knowledge.
"You mean, duck wings?!"
The man opposite didn't care too much about the man in the military coat spraying saliva on his face, but asked with some confusion:
"Isn't that the characteristic technology on Lao Maozi's fighter jets from the north?"
"Don't you think the Su-27 is a new fighter jet?"
The description of the man in the military coat makes it hard not to think of the Su-27 fighter jets our family imported from Damao's family.
After all, in today's world of fighter jets, they are basically the only fighter jets with canard wing designs.
However, in fact, the Su-27 fighter jets and Su-30 fighter jets introduced in China do not have canard designs.
Of course, it is difficult for ordinary people who are not professionals to distinguish these details.
Especially since 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 military coat also became a little excited at this time:
"That's definitely not Maozi's Su-27!"
"The Su-27 is a twin-engine fighter, and that plane is a single-engine fighter!"
"I must be right about this!"
The man opposite was also lost in thought at this time. After all, there were actually very few single-engine, canard-winged fighter jets in the world at this time.
All he could think of was the "Grippen" fighter jet, which was highly praised at this time.
However, if the country wants to obtain the "Griffin" fighter jet, it should be unlikely.
"Do you think this is a fighter jet developed by our family?"
The man in a military coat looked at the man opposite him who had fallen into silence and asked.
"I do not know."
The man opposite had no intention of having breakfast at this time.
"By the way, where did you see it? Can you show me?"
"It's right at the Chengnan Airport, but there are two sentries, 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, at this time also raised his head and looked at the two people sitting next to him.
After the two people left, they walked out of the breakfast shop and made a phone call:
"Commander Zhang, I just heard that two people seemed to be going to the airport to watch the planes."
"You ask the airport to check it carefully."
The improvement work of the WS-10 has basically reached the final stage, and the potential of this engine has basically been exhausted.
Zhang Zhengjiang has basically been spending time at military airports recently, doing the final work of adapting the WS-10 engine to the J-10.
This is also the reason why Zhang Xingyang told Zhang Zhengjiang about this matter. It was much more convenient for him to contact the airport than for him.
The main reason Zhang Xingyang came to Shengjing this time was to take a look at the extent of WS-10, which has reached its final stage of development.
The secondary reason was to discuss with Zhang Zhengjiang the next generation vector turbofan engine with high thrust and small bypass ratio.
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 research and development of a new generation engine is about to begin.
The wontons at the breakfast shop tasted so delicious that Zhang Xingyang burped after finishing the phone call.
The car that came to pick up Zhang Xingyang soon came from not far away.
Because he needed to go to the military airport this time, he did not let Zhang Xingyang take a taxi there by himself.
"Professor Zhang, you look quite young."
The young military man responsible for picking up Zhang Xingyang looked at the reflector and said with a smile.
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 are related to national security issues.
The security department staff even assigned Zhang Xingyang several security personnel hidden around him.
To prevent various dangers that may arise, especially assassinations from abroad.
Zhang Xingyang's current public identity is a newly promoted aerodynamics professor at the Aerospace University.
"Haha, actually I just look young."
The ride in the car was quite boring, and Zhang Xingyang still had some spare time to joke around with the young man.
"I'm actually in my forties."
There is nothing wrong with this sentence. If he lived in two lifetimes combined, he would be almost fifty years old.
"Huo!"
While the young man drove the car skillfully, he glanced at Zhang Xingyang's face, which looked like he was only in his twenties.
"Then you really look young."
"If you hadn't told me, I would have thought you were about the same age as me."
"Hahaha"
Zhang Xingyang also laughed at this time.
"I'm kidding you, but I'm actually only 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 would be awesome to be a professor now!”
Before the young man could continue chatting with Zhang Xingyang for a while, he had already arrived at the military airport.
After handing over the two procedures, Zhang Xingyang walked into the airport.
Before he walked into the engine maintenance center, he saw Zhang Zhengjiang waiting for him at the door:
"General Master Zhang, please excuse me."
"It's such a cold day and you came out to pick me up."
Zhang Xingyang walked up to Zhang Zhengjiang 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 here in another two months, that will be the coldest time!"
As a person who lived in a constant-temperature space base city in his previous life and basically lives in tropical and subtropical areas in the south in this life, Zhang Xingyang has experienced coldness a few times.
Almost all of them were felt in Shengjing.
This is truly an unforgettable city!
"Commander Zhang, how is the improvement of WS-10 now?"
Zhang Xingyang and Zhang Zhengjiang were walking side by side, preparing to go to the maintenance center to take a look at the condition of the latest WS-10.
In fact, the WS-10 at this time is almost different from the WS-10 Zhang Xingyang first saw more than two years ago.
In the official naming, his name has also been changed to WS-10S.
However, Zhang Xingyang is still more accustomed to calling him by his original name.
Just like what parents call the most affectionately is actually their child's nickname.
"The latest model WS-10S has basically reached its potential limit in terms of performance!"
Zhang Zhengjiang 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, 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 non-afterburning thrust of the engine is required It is 2.85 tons.
To put it simply, if the aircraft engine can exceed 2.85 tons without afterburner.
It is very possible to achieve supersonic cruise!
"Supersonic cruise is achieved?!"
This news was so important that Zhang Xingyang couldn't help but ask.
"In our latest flight experiment, the J-10 successfully completed supersonic cruise at Mach 1.15 without using afterburner!"
Zhang Zhengjiang also said very proudly.
This is indeed something to be proud of.
After all, before the F22 was officially released, supersonic cruise was almost impossible for fighter jets from various countries.
Most fighter jets can only fly at supersonic speeds briefly with afterburner turned on.
Although Zhang Xingyang also guessed that the flight experiment mentioned by Zhang Zhengjiang was most likely conducted without mounting missiles.
But in this era, even without missiles, fighter jets that can cruise at supersonic speeds basically do not exist.
"Such a result is probably the limit of this engine." Zhang Xingyang said relatively rationally.
"The J-10 can achieve this level without a built-in bomb bay."
"General Master Zhang, it's not easy for you either!"
Zhang Zhengjiang is still very modest, knowing that the WS-10S's ability to achieve such excellent performance is 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 extensive modifications, as well as several WS-10S engines that have been almost dismantled into parts.
Although the J-10 still has the same shape as before, many of its components have been improved.
Especially the few pieces of original carbon fiber and wings and vertical fins made of 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-size carbon fiber materials can not only increase the strength of the fighter's wings, but most importantly, can reduce the weight of the fighter.
This is also an important reason why the J-10 can carry out supersonic cruise after applying the WS-10S!
"Commander Zhang, have you started studying the vector nozzle problem of the engine now?"
Looking at the jagged composite material pieces on the ground that 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 took a look, he recalled a little and said:
"After we discovered that there was nothing that could be improved on the performance of the WS-10S engine."
"We have made some attempts at vector nozzles."
"But nothing has come of it yet."
Looking at this magically modified fighter in front of me, even the designers of the J-10 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 aircraft?"
"It seems that this level cannot reach the fourth generation machine, right?"
Zhang Zhengjiang thought for a while and then said:
"Maybe we can call it three and a half generations?!"
At this time, Zhang Xingyang thought of a joke in the future, smiled and said:
"We don't have any fourth-generation aircraft, we are just J-10 modifications!"
