Chapter 690

Can a duck shaped fighter plane have such a great attraction to the people of the kingdom of David?

Of course, it's still because of their own fighter development plan.

Although David imported F-15 fighters from Eagle, they did not give up their plan to develop their own fighters. In fact, they had developed lion cubs before, which was developed on the basis of phantom 5.

However, mirage 5 is the foundation of the second-generation aircraft after all. What they need is a high-performance third-generation aircraft. Due to the experience of mirage 5, their next-generation fighter is naturally delta wing. If they want to increase the performance of delta wing, they have to add canard wing.

Moreover, in this era, it happens that there is no finalized fighter with duck layout. How can you not be excited to see that there is such a smooth fighter here in the state of Han?

They said they would order super-7 fighters, which is also a compromise. By introducing the super-7 production line, they can have the ability to produce their own fighters. Then, they can transform the production line to produce their own duck layout fighters.

Others don't know, but Qin Guan knows very well that in history, this is the famous Lavi fighter. In fact, their project has begun.

Although we have started to develop a fighter from scratch, there must be many difficulties. What if we have the experience of a mature company for reference?

Unfortunately, although Qin Guan proposed to inadvertently expose the model of the J-10 prototype to them, the air force is still unwilling. This No. 10 project has the highest level of confidentiality and must not be displayed to foreigners.

The holy state is an exception. I've seen it before. That's because the relationship between the holy state and the Han state is the most iron. Other countries can't do it, nor can David.

At this time, Qin Guan made a compromise plan. Since the J-10 was not good, the j-9 was absolutely no problem.

The j-9 project is now regarded as a abandoned project, and 6611 institutes have achieved a lot after ten years of experience in the j-9 project. These achievements are also kept. They simply take them out to deceive people.

As for the release of the J-10 to the outside world in the future, some say that we have improved on the basis of the j-9.

Now, looking at the expressions of these people in the kingdom of David, it's like seeing women. Qin Guan knows that there must be a play.

Come on, let's take a look at the latest scientific and technological achievements of Han. I'm sure you'll be surprised.

"Can we see that fighter?" Rafael said, spitting.

If you accidentally see the other party's secret, it's ok if the other party doesn't pursue it. Now, you have to go and see what's going on. This requirement is a little too much, but they can't help it.

The expression on Tu Lao's face was very complicated. He also stamped his feet, as if to say, who did it? Didn't you let you cover the plane first?

Where's the cloth that covers it?

The cloth was on one side. I don't know what happened, but it slipped down?

"Then go and have a look." Qin Guan said, "everyone, please note that this is our top secret. It should never be publicized."

Qin Guan said that the visitors to the kingdom of David certainly nodded like chickens pecking rice: "OK, of course, we don't say anything. We don't say anything."

This is a fighter with a slender body and a huge triangular wing at the back, which constitutes its most symbolic aerodynamic layout. The nose adopts air intake on both sides, and the canard wing is above the air inlet. At this time, when the visitors of David approached, they found that this is not a real aircraft, but a full-size wooden model.

"This is our jian-9 fighter," Qin Guan said. "Our project has been going on for ten years."

In a simple sentence, it explains a lot of things.

For example, the super-7 fighter is named j-14. What's going on? From the jian-8 to the current jian-14, there are many models.

For example, the present is jian-9.

Why is it called jian-9? Because it has been going on for a long time for ten years, this number was determined at the time of initial development. Although the super-7 made the fastest progress, its project was the latest, so it was the turn of the j-14.

Qin Guan's explanation was acceptable to all the people of the kingdom of David present.

"Because this is our first canard type fighter and the basic problems of our aviation industry in recent years, this aircraft has been conducting aerodynamic research. We have blown the wind tunnel for several years and accumulated a lot of data. Now, it's time to accumulate a lot," Qin Guan said.

This is not a flicker. If the data of the jian-9 wind tunnel can be exchanged for more good things, Qin Guan is absolutely willing.

Qin Guan can't wait for so many good things in the kingdom of David. What's more, some of them said that they would improve and improve again!

"It's a pity that it doesn't use belly air intake. The performance at such a high angle of attack is not enough," lafar said.

As like as two peas in the air, it will be almost the same as their LAVI plan, so that if they are introduced, they will be able to speed up their project plan.

"Yes, if the belly air intake is adopted, the high angle of attack performance will be greatly increased. However, what we need for this aircraft is not high angle of attack, but long-distance interception capability." Qin Guan said: "our combat target is Xiong Guo's bomber."

Whether it is the J-8 or the j-9, when they are developing them, they are aimed at intercepting Xiong's bombers, which is the greatest threat.

Since it is an interceptor, it does not require high angle of attack performance, but high-speed attack capability.

Now, Qin Guan explained this, and the other party nodded and accepted, while Qin Guan continued to deceive: "of course, if it is changed to the air intake in the belly, there will not be too many problems. We have accumulated a lot of data. As long as we make a little improvement, for example, if we can get in touch with the F-16 fighter, we can graft its body."

Because of the limited technical capability of the people of David, although they say they are self-developed Lavi fighters, the whole body looks almost like the F-16.

It just changed the airfoil into a large delta wing at the back and a canard wing at the front, which gave the fighter better maneuverability.

Qin Guan's words almost hit the heart of the people of David, because almost this is their own plan!

Then, Qin Guan continued to say, which made them even more excited: "after a lot of experiments, we finally determined its flight control rate. If this kind of aircraft wants to have quite good performance, we must work hard on the control system. Relying on the progress of our country's electronic technology, we intend to adopt four redundancy digital telex."
