"I'll dictate it to you." The lights were turned on, and Boileau regained his composure.

I can't put it in the back, it's all specific structural drawings, design drawings, and top-secret information, who knew that I was so careless and brought these slides.

Boileau was already secretly scolding in his heart, and he had to pretend to be smiling, and began to understand to everyone, now it's okay, let's talk about it.

"Our Mirage 2000 adopts the same tailless delta wing aerodynamic layout as the Mirage III, in order to give full play to the advantages of small supersonic drag, light structural weight, good rigidity, low chatter at large angles of attack, low wing load interception, large internal space and more oil storage."

"Compared to the Mirage III, the wing load is reduced by about 10 percent, the wing area is increased by 15 percent, the approach speed is 20 percent lower, and the climb rate is twice that of the Mirage III. The progress of the process has allowed us to use a large number of carbon fiber and boron fiber composite materials, and the weight of structural components has been reduced by 15~20%. New technologies such as fly-by-wire control, relaxed static stability, and composite materials have been adopted to improve aerodynamic characteristics and flight performance, and a new turbofan engine has been adopted to increase the range. ”

Boileau said with a splash of foam, but such an explanation, after all, was dry, and by the time he finished the general content, everyone listened to it without enjoyment.

"Mr. Boileau, can we see the actual machine?" General Lin asked.

"This real plane will participate in tomorrow's air show, everyone can feast their eyes tomorrow, today, everyone came from afar, they are tired, please rest." Boileau said.

Instead of walking on the brightly lit streets, not going to experience life in the brightly lit capitalist world, after returning to the room, Qin Feng quickly opened a piece of paper, then took out the pencil on the hotel table and drew it quickly.

The structural diagram is often seen in aviation science and technology magazines, but it is a variety of models that have been in service for a long time, and a prototype like this has never been seen.

I happened to see the structural diagram today, apparently the other party inadvertently made a mistake, this aircraft is the most advanced, its structural diagram, that is also a great reference value, I rely on memory, draw it back, although the proportions may not be appropriate, there will be some mistakes, but, in short, it is a reference.

After I went back, I took the time to send it to Song Lao.

The Phantom 2000 is a delta wing layout without a tail, and the J-9 of the 611 Institute is equivalent to adding a canard wing in front of it, which leads to the difference in aerodynamic layout, but at least the fuselage is of reference significance, and he has gained a lot this time, and Song Lao will be happy to see it.

In the past, Qin Feng used to learn sketching, but now he draws very quickly, and sometimes he forgets it, and he will stop and recall.

"Knock knock." There was a knock on the door outside.

"The door is unlocked." Qin Feng shouted in English, in his eyes, he thought it was the service staff in this hotel, who came in with a garbage or something.

"Hey, what are you drawing?" General Lin's voice came from behind him, instantly making Qin Feng jump up: "I'm scared to death." ”

General Lin ignored Qin Feng, stared at this picture, and said, "You have such a good memory, it's just unforgettable." ”

"General Lin, the French must have taken it wrong today, this opportunity was not easy to come by, I want to take it back to Song Lao and them for study, by the way, you should know Song Lao's J-9 project, right?"

General Lin nodded.

"Our J-8, just to solve the problem of whether there is or not, if you want to have good performance, you have to look at the J-9, I also participated in the J-9 project, I feel, this project came out, not necessarily worse than the Mirage 2000, although it is designed in accordance with the high-altitude and high-speed indicators, but we also refer to a lot of modern fighter design indicators, out of it must be a good air control fighter."

General Lin patted Qin Feng on the shoulder, with a smile on his face: "Young man, the future of our Air Force depends on you." ”

Speaking of this, a trace of frustration suddenly flashed on his face, the J-9 project, although it looks more attractive, is a pity.

Now that the final decision of the superiors has not yet come down, don't hit the confidence of young people like Qin Feng, if the country wants to transform to economic construction, some projects must be cut, these are things that can't be helped.

"General Lin, listening to their introduction today, the avionics of the Mirage F1 are already good for us." Qin Feng finally seized this opportunity, he was a small pilot, a general of the Air Force came here to chat with him, it was a rare opportunity, report his thoughts!

"Yes, our country's electronic technology is too backward." General Lin said: "So we have to seize the current hard-won opportunity to introduce from abroad, Tu Lao has begun to talk to the British about the introduction of Marconi's avionics, and the superiors are discussing, taking this opportunity to introduce a few J-8 models." ”

"Let's introduce radar first." Qin Feng said, even if the 204 radar is successfully developed, it is still a backward single-pulse radar, and the West has long begun to pulse Doppler radar, if it can be introduced, it will instantly make the J-8 a generation ahead.

"In terms of radar, the superior has already issued instructions, the J-7 originally planned to introduce pulse Doppler radar, but now it has been changed to introduce radar rangefinders, pulse Doppler radar and inertial navigation systems, which are introduced by the J-8 project."

"That's great!" Qin Feng said excitedly, I didn't expect that there would be an inertial navigation system. That's standard for long-range fighters.

In fact, there is good news, the Air Force is backward in equipment, everyone knows it, the Air Force has been waiting for the domestic aviation industry, how many years have it been waiting, and there is no decent fighter, now that the country is open, if possible, the introduction of a batch of fighters from abroad will immediately improve the combat effectiveness of the Air Force.

It's just that there are many variables in this proposal, and the most critical point is that the country is poor.

General Lin couldn't help but feel a lot of emotion in his heart.

If we want to have a strong national defense, we must have a strong country, and now that the country wants to reform and engage in economic construction, the army will have to tighten its belts for a long time.

This time, France took the initiative to invite itself to see the world, that is the best, thinking of this, General Lin has some expectations, tomorrow at the air show, will definitely see France's most advanced Mirage 2000 fighter, right?

If the opportunity is good, the introduction of this fighter into the country, then it can solve the current urgent need, the J-8 engaged in 601, to be honest, General Lin doesn't like it at all, but there is no way.
