Chapter 12 Surprise! Isn't this an F22 fighter jet? Where did this thing come from? (Please collect and read!)
"Lao Xu, I'm afraid this surprise is bigger than you expected!" Song Qinyi said cheerfully.
Hear the words.
All the J-20 project team leaders present here had a somewhat casual look in their eyes, but now they became extremely serious.
‘You can’t really be guessed by this barbarian,’ several people thought to themselves.
Could it be said that there are really any new technological breakthroughs in the J-20 project recently? Can the engine performance be greatly improved?
But that shouldn't be the case. As the leaders of the project team, why haven't they heard of these gossips recently? This is a very good job of keeping it secret!
"Old Song, stop hiding there and announce the news quickly!" The old man with a weathered face next to him was a little impatient.
"The tasks of our R&D team are still waiting for me to handle. Don't waste time."
As a team that develops avionics systems, he has a lot to do.
After all, which of the avionics equipment on a modern fighter jet can be saved? It doesn't mean that you can just install each module directly.
It would be very simple to develop first-generation discrete avionics systems like the J-7 and J-8.
After all, the equipment radar module, fire control system, etc. are all independent of each other. You only need to install everything. The price is that they cannot cooperate with each other. Each one requires manual operation by the pilot, and the failure rate is extremely high. The difficulty is high and the combat ability is seriously lacking.
However, the J-20 is a fifth-generation aircraft, and its design requirements are based on the F35 fighter jet, which has not yet officially entered service. It uses the fourth-generation advanced integrated avionics system.
Each subsystem needs to be connected in series with each other, with perfect coordination, highly integrated sensing linkage, and powerful core processing and computing capabilities. Even the pilot's human-machine interaction must reach a new level!
He was having a headache over how to achieve this outrageous avionics system, and just wanted to end the meeting quickly.
Hear this.
Song Qinyi didn't have any ink marks, and the smile on his face disappeared. He stared at everyone and said, "Next, the confidentiality level of the news I will announce is: top secret!"
"All communication equipment is turned off and handed over to me."
"Top secret? Old Song, what big news are you going to make this time?" Xu Qing handed over the phone he was carrying with a look of horror on his face.
He has participated in so many meetings since he entered the J-20 project, but this is the first time he has encountered this situation!
The expressions on the faces of everyone present suddenly changed. What this meant was very clear to them, old aviation people.
Even when the J-20 project was secretly established in 2007, it didn't reach this level, right?
This also means that the level of confidentiality of this news is far beyond that.
What is the big news that is even more important than the J-20 project?
"You'll know in a minute!" Song Qinyi narrowed his eyes and placed all these devices in the next room, then turned on full-band signal interference to prevent any information from leaking out.
It's not that Song Qinyi doesn't believe these people here. On the contrary, Yingjiang doesn't know that Daxia's fifth-generation aircraft project is in intensive development until now.
This is enough to prove that no one has leaked any information.
However, in the face of such absolutely confidential information, Song Qinyi could only choose the most cautious approach.
Returning to his position, he faced everyone's extremely curious eyes.
"First of all, we experimented with a brand new aircraft model some time ago, and the data obtained are as follows!" Song Qinyi opened a PPT, and the data were listed one by one on the upper screen.
[RCS: 0.002m] (Radar reflection area)
【Lift coefficient: 1.65】
[Super Cruise Zero Lift Drag Coefficient: 0.035]
【.】
Looking at the data displayed on the screen and the extremely familiar model aircraft, the expressions of everyone present changed.
Why does this thing look more and more familiar to them?
Not only the appearance of the aircraft model in the picture, but also the data give them an unusually familiar feeling. "The radar reflection area is 0.002 per square meter. The super patrol zero lift-drag coefficient. Why does this data look so familiar to me?"
"Except that the lift coefficient does not match a small part of the other data, the other data are exactly the same!"
“Isn’t this waverider structure data and aerodynamic layout an F22 fighter jet?”
It can be said that except for the appearance of this model aircraft, which is painted in the Daxia camouflage color, its appearance is very similar to the F22.
No, they can be sure that this model aircraft is definitely a fake F22 fighter jet.
Where did this thing come from?
However, this slight hesitation only flashed through everyone's mind.
Several heads of the R&D team present shouted excitedly:
"Old Man Song's technology is good, and its performance in all aspects is so excellent?"
"With the stealth performance and supercruise resistance solved, it will be easy to handle! Our research and development progress can be improved by at least a few months."
"Is it just about aerodynamic layout and materials? Don't we have any new technologies in our avionics system?"
The overall performance of this TM is terrifying! !
They don't care where the aviation simulation technology comes from, they just need to see the results.
As long as the performance of the fighter jets is improved, it is enough, even if it falls from the sky, it doesn't matter.
Could it be that they won’t use it just because it’s a technology that imitates the F22 fighter jet?
Just kidding, they will only use it more vigorously! Crossing the river by feeling the eagle sauce, isn’t this a fine tradition in Great Xia?
only.
"Old Song, the lift coefficient is not enough. Why is it only 1.65?"
"Not to mention the engine has been significantly improved, it's good if it doesn't hold back!" Xu Qing next to him said very dissatisfied.
You know, the set target value of the J-20 is to reach a lift coefficient of 2.0, which is currently far behind.
Such a poor lift coefficient will definitely lead to a decline in the fighter's flight capabilities.
Xu Qing shook his head: "Even if you add a canard layout to this aircraft model, the lift coefficient will increase to 1.85-1.88 at most, which is still a little bit behind..."
Although it is better than the current lift coefficient, it is not much.
The most critical reason why the J-20 does not use this traditional layout method is that the lift coefficient does not meet the requirements.
Only by adding a canard layout can the lift coefficient be greatly improved.
Even though the controllability and control difficulty will increase, and the pilot's technical and tactical requirements will be higher, this is a necessary sacrifice in order to achieve a lift coefficient of 2.0.
After all, the J-20 lags behind the F22 in terms of engines and other aspects. It can't even catch up with the most basic lift coefficient!
How can it be called a fifth-generation heavy-duty air superiority aircraft like that?
Hearing this, everyone was filled with excitement.
All of them knew how much the lift coefficient affected fighter jets.
This is one of the most important data of a fighter jet. It has a significant impact on all aspects of flight, such as maneuverability, speed, etc., each of which is related to the lift coefficient.
"Yes, so we use new materials!" Song Qinyi clicked on the next PPT!
"This high-strength carbon fiber composite material improves the layout of the J-20, and the lift coefficient will successfully reach 2.2!"
All I saw was a brand new set of data listed on the picture!
After using a large amount of new materials, the J-20 with a canard layout can achieve a lift coefficient of between 2.1 and 2.2 even if it uses Lao Maozi's AL-31F turbofan engine.
"Also, who said that the lift coefficient of F22 is 2.0!" Song Qinyi couldn't help but complain.
"It is absolutely impossible for them to achieve the data that we cannot achieve."
Yingjiang's bastard is really harmful to people. A false data has tortured them for several years.
