Chapter 12 Surprise! Isn't this an F22 fighter? Where did this thing come from? (Please collect and read!)
"Lao Xu, this surprise may be bigger than you expected!" Song Qinyi said happily.
Hear the words.
All the J-20 project team leaders present, who had originally had a somewhat careless look in their eyes, now became extremely serious.
"Could it be that this barbarian Xu really guessed it right?" several people thought to themselves.
Could it be that there is really some new technological breakthrough in the recent J-20 project that can significantly improve the engine performance?
But it shouldn't be like this. As the project team leader, how come they haven't heard about these rumors recently? They are so good at keeping it secret!
"Old Song, stop hiding it and announce the news right away!" The old man with a weathered face next to him was a little impatient.
"Our R&D team's tasks are still waiting for me to handle. Don't waste time."
As a member of a team that develops avionics systems, he has a lot to do.
After all, which avionics equipment on a modern fighter can be worry-free? It's not like you can just install each module directly.
It would be very simple to develop a first-generation discrete avionics system like the J-7 and J-8.
After all, the radar modules, fire control systems, and so on are all independent of each other. You just need to install everything on it. 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 flight difficulty is high, and the combat capability is seriously insufficient.
However, the J-20 is a fifth-generation aircraft, and its design requirements are benchmarked against the F35 fighter jet, which has not yet been officially put into service in the United States, and it uses a fourth-generation advanced integrated avionics system.
The various subsystems need to be interconnected, work together perfectly, have highly integrated sensor linkage, and powerful core processing and computing capabilities. Even the pilot's human-computer interaction must reach a new level!
He was racking his brain over how to achieve this outrageous avionics system and just wanted to end the meeting quickly.
Hear this.
Song Qinyi didn't waste any time. He put away the smile on his face, stared at everyone and said, "Next, the confidentiality level of the news I am announcing 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 reveal this time?" Xu Qing handed over the phone he was carrying with a look of horror on his face.
He has attended so many meetings since joining the J-20 project, but this is the first time he has encountered such a situation!
The expressions of everyone present suddenly changed. As veteran aviation professionals, they knew exactly what this meant.
Even when the J-07 project was secretly launched in 20, it didn't reach this level, right?
This means that the news is much more confidential than it actually is.
What kind of big news is this that is even more important than the J-20 project?
"You will know soon!" Song Qinyi narrowed his eyes, put all the equipment in the next room, and then turned on the full-band signal interference to prevent any information leakage.
It's not that Song Qinyi doesn't trust the people present. On the contrary, the Americans are still unaware that Daxia's fifth-generation aircraft project is under intensive development.
This is enough to prove that no one has leaked any information.
However, faced with such absolutely confidential information, Song Qinyi could only choose this most cautious approach.
Returning to his position, he faced everyone's extremely curious gazes.
"First of all, we experimented with a brand new aircraft model some time ago, and the data we obtained are as follows!" Song Qinyi opened a PPT, and the data were listed on the screen above.
【RCS: 0.002m】(Radar reflection area)
[Lift coefficient: 1.65]
[Supercruise zero-lift drag coefficient: 0.035]
【.】
Looking at the data displayed on the screen and the extremely familiar model aircraft, everyone present changed their expressions.
This thing...why does it look more and more familiar to them?
Not only the appearance of the model aircraft in the picture, but also the data gave them an unusually familiar feeling. "Radar reflection area 0.002 per square meter Super cruise zero lift-drag coefficient. Why do these data look so familiar to me?"
"Except for the lift coefficient and a few other small parts, the other data are exactly the same!"
"Isn't this waverider structural data and aerodynamic layout an F22 fighter?"
It can be said that except for the fact that the exterior of this model aircraft is painted in Daxia's camouflage color, the rest of its appearance is very similar to the F22.
No, they can be sure that this model aircraft is definitely a replica of the F22 fighter.
Where did this thing come from?
However, this slight hesitation only flashed through everyone's mind.
Several R&D team leaders present shouted excitedly:
"Old man Song's skills are really good. The performance in all aspects is so excellent?"
"Now that stealth performance and supercruise resistance have been solved, this is going to be easy! Our research and development progress can be accelerated by at least a few months."
"Is it only about aerodynamic layout and materials? Is there no new technology in our avionics system?"
This TM comprehensive performance is so terrifying! !
They don't care where the technology for aircraft manufacturing comes from, they just need to see the results.
As long as the performance of the fighter jet is improved, it doesn’t matter even if it falls from the sky.
Are they going to stop using it just because it's a copy of the F22 fighter's technology?
Are you kidding? They will only use it more vigorously! Crossing the river with the help of the eagle sauce, isn't this a fine tradition of Daxia?
only.
"Old Song, this lift coefficient is not enough. Why is it only 1.65?"
"Don't even mention a significant improvement on the engine. It's good enough that it doesn't lag behind!" Xu Qing next to him said very dissatisfiedly.
You know, the set target value for the J-20 is a lift coefficient of 2.0, which is currently a long way off.
Such a poor lift coefficient will definitely lead to a decline in the fighter's flight capability.
Xu Qing shook his head: "Even if we add a canard layout to this model aircraft, the lift coefficient can only increase to 1.85-1.88 at most, which is still a little short..."
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 is that the lift coefficient does not meet the requirements.
Only by adding the canard layout can the lift coefficient be greatly improved.
Even though the maneuverability and difficulty of control will increase, and higher technical and tactical requirements will be placed on the pilot, 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 cannot fail to catch up with the most basic lift coefficient!
In that case, how can it be called a fifth-generation heavy air superiority aircraft?
Upon hearing this, everyone's excited expressions paused.
They all knew very well how great an impact the lift coefficient had on a fighter jet.
This is one of the most important data for a fighter jet, and it has a significant impact on all aspects of flight, including maneuverability, speed, etc. Each one 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!
With a large amount of new materials, the J-20 with a canard layout can achieve a lift coefficient of between 31 and 2.1 even when using the Russian AL-2.2F turbofan engine.
"Besides, who said the lift coefficient of F22 is 2.0!" Song Qinyi couldn't help but complain.
"The data we can't achieve, they definitely can't achieve it either."
The Eagle Sauce is really harmful to people. A piece of false data has tortured them for several years.
