In later generations, the F-22 of Eagle Kingdom has existed as a king for a long time, dominating the sky. Therefore, Eagle Kingdom also uses it as a weapon of killer mace, which is the trump card among trumps.

Why is it so powerful? People rely on alien technology. The powerful F119 engine developed has a thrust weight ratio of 10.

For a long time, even by 2020, there is no such technology in China. However, China has also achieved this goal. The jian-20 of China is a stealth fighter in service outside the eagle country. You know, China's aviation technology has been making continuous progress, but the engine is still a weakness.

Even generally speaking, the j-20 still uses an engine like San Yifu, but what does it rely on to achieve the design goal? Of course, it is the outstanding aerodynamic layout to make up for it.

Aerodynamics and stealth seem to be contradictory. If the aerodynamic layout is taken into account, the invisibility will be poor. If the invisibility is taken into account, the aerodynamics will be terrible. How to compromise? It depends on the people in front of you.

At the beginning, after building the J-10, old song handed over the remaining tasks to Xiao Yang. Later, old song continued to develop new fighters with his pneumatic team. When the j-20 came out, the perfect combination of aerodynamics and stealth was built by old song.

In the past, Mr. song could do it, so now, Mr. Song must be able to do it.

In his life, Mr. Song was best at pneumatic layout.

Now, hearing the question of old song, Qin Guan smiled: "old song, this question should not be asked by you, but by me."

Old song's body was shocked. Yes, he was the aircraft designer.

"Mr. Song, it will take some time for our Raptor test flight. When the Raptor test flight is over and the troops are equipped, you can pre research the next project. In this way, once the air force needs and puts forward the indicators of the next generation of fighters, you can come up with a mature scheme."

In later generations, in the 1980s, the air force needed three generations of aircraft, but now, with the breakthrough of the Raptor, the air force will certainly continue to keep up with the world's advanced level. For example, the stealth fourth generation aircraft will be developed almost synchronously when Eagle country puts forward the standard. Perhaps, its progress will be faster!

Well, by the time the bear state disintegrated and the eagle state dominated the world in the 1990s, the Han state had achieved a significant leap forward development of the army, and there would be no humiliation in the 1990s, and even the rise of the Han state could be realized in advance.

Yes, that's it!

Qin Guan thought of this and became very excited.

On the fourth generation aircraft, I don't have much help. After all, I can't exchange either the F-22 or the j-20, because they don't enter the aircraft cemetery, even the prototype.

I can't exchange the whole machine and I can't get the technical data. I can only put forward the scheme. If I want to do it, I only have the F-117.

Wait until later.

"Now, our fighter has been calling the Raptor." at this time, an air force officer said, "General Zhang, after the test flight of the Raptor, it will certainly enter our air force. Should we give it an official number?"

After three rounds of drinking, everyone's topic is still inseparable from the Raptor. At this time, when we heard the officer's words, we remembered that, yes, we haven't numbered it yet?

What number should I give?

6611 Institute, which has been studying in advance before, is the j-9, which is also a duck layout aircraft, but now this one is also a duck layout, or is it also called j-9?

General Zhang was thinking, and Qin Guan had said, "I remember when the project was approved last year, it was called project 10? How about simply calling it J-10?"

Yes, last year, when the imitation was carried out, there was no military number. It was inside the system. It was called project 10. Now if you want to number it, it's called J-10.

Historically, it is J-10 and j-9. It is a project destined to be dismounted. Who can achieve the target of double 26? Look at the F22 of later generations. The fastest speed is Mach 2, but people can go to Mach 1.6 without afterburner.

Stealth is to keep the fighter from being discovered by the enemy and can approach secretly, while supersonic cruise is to reach the battlefield faster.

Today's fighters are supersonic, but only when the afterburner is turned on can they achieve supersonic speed. As we all know, after the afterburner is turned on, the engine is like injecting stimulants. Although the power is greatly increased, the fuel consumption rate is soaring. If the normal flight can fly for one hour, the afterburner will be turned on and the fuel will be gone in ten minutes.

If supersonic cruise can be realized without afterburner, it can greatly increase the dispatch efficiency, reach the battlefield as soon as possible, and facilitate rapid withdrawal from the battlefield.

Because the engine is abnormal, there is no problem with short-range takeoff. As for the final super mobility, it is actually a little chicken rib, which is used for close combat. However, no user of the expensive stealth fighter is willing to use it for close combat, and generally uses medium-range bombs to end the battle.

It's not cost-effective to fight. If you get killed and lose too much, it's entirely possible in the battle. You can kill the teacher with random fists.

Think more. Now, Qin Guan proposed to call it J-10, and no one objected. General Zhang, the commander of the air force, made a decision almost immediately: "yes, it's J-10. This is our new third-generation aircraft. It's different from j-9. It's also called j-9. It's easy to be misunderstood. I thought I kept the original target."

Although they are all duck layout, after all, they are different from the previous j-9.

Now, Xinjian has the number given by the air force, that is to say, it is almost certain that Xinjian will be purchased by the air force, and everyone present is very excited.

"Come on, cheers to our J-10!" old song raised his glass.

"Old song, you can't drink any more." Qin Guan said quickly.

Everyone is very happy today, but there must be no accident at this celebration. It doesn't sound good.

However, Mr. Song obviously didn't listen. After all, Mr. Song held back for so many years for the duck layout of the fighter. Today, he finally saw it rise in the air. No one feels more excited than Mr. Song. His child is finally going to be born.

Therefore, Qin Guan could only quickly switch off the topic.

"So, does the air force also give a number to our super seven fighters?"

Hearing Qin Guan's words, everyone stopped immediately. It seems that something is wrong?
