Chapter 690: Introducing our J-9

Can a duck-type fighter plane be so attractive to the people of the Kingdom of David?
Of course it is because of their own fighter development plan.
Although David Nation imported F-15 fighters from Eagle Nation, they did not give up their plans to develop their own fighters. In fact, they had developed the Cub fighter before, which was developed on the basis of Mirage 5.
But the Mirage 5 is the foundation of a second-generation aircraft after all. What they need is a high-performance third-generation aircraft. Because of the experience of the Mirage 5, their next-generation fighters are naturally delta wing. If you want to add performance to the delta wing, then Need to add duck wings.
Moreover, in this era, there hasn’t been any aircraft with a duck-like layout. How can you not be excited when you see a fighter with such a smooth appearance in Han?
They said they wanted to order Super Seven fighters, which was also a compromise. By introducing the Super Seven production line, they were able to produce their own fighters. Then, they could transform the production line to produce their own duck-shaped fighters. .
Others don't know, but Qin Guan knows very well that in history, this is the famous LAVI fighter, and their project has actually begun.
Although it has started, developing a fighter aircraft from scratch will definitely encounter a lot of difficulties. If there is a mature company's experience to refer to it?
It is a pity that although Qin Guan proposed to expose the prototype of the J-10 to them inadvertently, the Air Force was still unwilling. The No. 10 project has the highest level of confidentiality and must not be shown to foreigners.
The exception is the holy country. I have seen that because the relationship between the holy country and the Han country is the most ironic. Other countries will not work, nor will the David country.
At this time, Qin Guan made a compromise plan. Since the J-10 is not enough, then J9 is absolutely no problem.
The J-9 project is now considered to be an abandoned project, and the 6611 Institute, which has experienced ten years on the J-9 project, has also had a lot of results. These results are kept, and they are simply taken out to fool people. .
As for the future release of the J-10 and open it to the outside world, some people say that we have improved on the basis of the J-9.
Now, looking at the expressions of these people from the Kingdom of David, it was like seeing a woman, Qin Guan knew that there must be a show.
Come on, let's take a look at the latest scientific and technological achievements of Han Guo, I promise to surprise you.
"Can we look at that fighter?" Rafael said after swallowing.
I accidentally saw the secret of the other party, and the other party didn't pursue it. Now, I have to go and see what happened. This request is a bit excessive, but they can't help it.
The expression on Old Tu’s face was very complicated. He also stomped his feet, as if saying, who did it, didn’t you let you cover the plane first?
What about the cloth covering it?
That piece of cloth was on the side. I don’t know what happened, but it slipped down?
"Then go over and take a look." Qin Guan said, "Everyone, please pay attention to this. This is our top secret, and it should never be disclosed to the outside world."
Qin Guan said that the few visitors from the Kingdom of David, of course, are like chickens pecking rice: "Okay, of course, we don't say anything, we don't say anything."
This is a slender fighter plane. The large delta wing at the back constitutes its most iconic aerodynamic layout. The nose adopts air intake on both sides, and the canard is above the air inlet. At this time, when After the visitors of the Kingdom of David approached, they realized that this was not a real machine, but a full-size wooden model.
"This is our J-9 fighter." Qin Guan said: "Our project has been underway for ten years."
A single sentence can explain a lot of things clearly.
For example, the Super Seven fighter was named F-14. What's going on? From the J-8 announced to the public to the current J-14, there are still many models.
For example, the current one is J-9.
Why is it called Jian Jiu? Because it has been in operation for ten years and it has taken a long time, this number was determined when it was first developed. Regardless of the fastest progress of Super Seven, its project is the latest, so it is the J-14's turn.
Qin Guan explained that it was acceptable to all the people in the Kingdom of David.
"Because this is our first duck-type fighter aircraft, and the basic problems of our aviation industry over the years, this aircraft has been conducting aerodynamic research. We have been blowing wind tunnels for several years and accumulated A lot of information, now it's finally time to accumulate a lot of information." Qin Guan said.
This is not a flicker. If the information on JJJiu's blowhole can be exchanged for more good things, Qin Guan is absolutely willing.
With so many good things in the Kingdom of David, Qin Guan can't wait long ago. More importantly, if he improves and improves, some have said!
"It's a pity, why doesn't it use belly air intake, so the performance at such a high angle of attack is not enough." Rafael said.
If it is replaced with belly air intake, it will be almost identical to their LAVI plan. In this way, if this technology is introduced, their project plan can be greatly accelerated.
"Yes, if you use belly air intake, the high angle of attack performance will greatly increase, but what our aircraft needs is not high angle of attack, we need long-range interception capabilities." Qin Guan said: The combat target is the bomber of the bear country."
Whether it is the J-8 or J-9, when they are developing, they are all aimed at intercepting the bear country's bombers. This is the biggest threat.
Since it is an interceptor, it does not require high angle of attack performance, but requires high-speed attack capability.
Now, Qin Guan explained that, the other party nodded and expressed acceptance, and Qin Guan continued to flicker: "Of course, if it is changed to belly air intake, there will not be too many problems. We have accumulated a lot of data. Now, just a little improvement. For example, if we can get access to the F-16 fighter, we just need to graft its body."
Because of the limited technical capabilities of the David Nationals, although they say they are self-developed LAVI fighters, the entire body looks almost copied from F-16.
It just changes the airfoil into a large delta wing at the back and a canard at the front, which gives the fighter more excellent maneuverability.
What Qin Guan said was almost exactly what David's nation wanted, because it was almost their own plan!
Then, what Qin Guan continued to say made them even more emotional: "After a lot of experiments, we finally determined its flight control rate. For this kind of aircraft to have quite good performance, it must be up and down the control system. Kungfu. Relying on the advancement of our country’s electronic technology, we intend to adopt more than four-degree digital telex."
