"Didn't you tell us to come to the meeting to review the new machine plan?"

Song Wencong was a little surprised, the difference between this selection and participation is big. The main job is to listen to the introduction of the fighter design plan and then evaluate the plan.

First of all, it is necessary to have a candidacy plan, right? How long did it take for a fraternal unit to come up with a candidacy plan? The country's largest design institute, with hundreds of designers, took two months.

Now, if he wants Song Wencong to run for election, what time will he have to organize the plan? It will not take more than three days.

How many people can be used? No more than four people.

If you want the 611 Institute to run for election, at least when you were notified, it shouldn't be for him to come over to advise and improve this rhetoric, right?

Deputy Director Wang was also stunned, his face changed slightly, but he still reluctantly nodded and said: "Yes, this meeting is mainly to review the new annihilation plan, but it does not exclude that there are other better new annihilation plans! Have you done many new annihilation plans in the past?"

Song Wencong thought about it and nodded.

Since the dismount of the Jian-9 fighter, Song Wencong has continued to study the overall layout of the fighter and tactical interception. At the 611 Institute, he organized a new specialty, tactical performance and vision development group, which was responsible for broadening the minds of the people to explore new options. The work of this group is to be responsible for innovation, and every year several new annihilation plans must be put forward for discussion so that they can be selected when necessary.

When Guizhou received a call from the institute to go to Beijing, he asked the people who had rushed to the institute to bring all the materials of the research work in the past few years for backup.

Obviously, the matter of this group opened up by Song Wencong has also reached the ears of the leaders of the Ministry of Aviation Industry.

"We've done some plans, but the meeting didn't ask us to bring a new plan!" he was still a little strange.

Deputy Director Wang said bitterly: "This meeting has attached great importance to this meeting from the Central Military Commission, the Commission of Science, Technology and Industry for National Defense to the Ministry of Aviation Industry, and so many experts have come. Although the time you have not been in place for a long time has been very long, after all, it is also a fighter aircraft research institute! Since you have come here, it is a rare opportunity, and at the meeting the day after tomorrow, you should talk about your basic ideas on the development of the new war. In addition, Lu Xiaopeng of Nanchang also brought a plan for changing the swept wing, the radar of the 607 institute and the engine of the 606 institute, and they also had to talk about it. ”

Song Wencong actually had an intention in his heart, but he didn't show a smile on his face, and asked again: "But I see that on the agenda of the meeting, there is no time for us to speak, right?"

"In this way, I'll tell the meeting when I go back!" Deputy Director Wang hesitated for a moment and said, "Let's make a temporary arrangement, you see, how much time will it take?"

Song Wencong's heart was overjoyed, but he still pretended to be very embarrassed, and muttered: "I see—it's only about a quarter of an hour." ”

"Okay, that's it! You should hurry up and make preparations, and when you introduce the plan at the meeting, try to be as concise as possible. ”

After Deputy Director Wang finished speaking, he hurriedly went to the conference affairs team.

It will be arranged on a temporary basis without prior notice. The Ministry of Aviation Engineering gave Song Wencong a surprise attack, and the four of them waited for Deputy Director Wang to leave, and hurriedly held a meeting.

Time was tight, and there was no chance to complain, so the four of them anxiously began to prepare.

No tools, no materials, nothing to prepare. The four of them had to go around to find a few blank gelatin sheets that they could use to make slides.

Fortunately, in the past few years, Song Wencong has long been familiar with their new annihilation plan, and Xie Pin even simply spent the three views and performance tables of the new annihilation plan with his bare hands.

It will not be until the dead of night, in the middle of the moon, that the preparations will be completed. Song Wencong and the four of them barely slept for a while with apprehension, and the morning meeting time had already begun.

The venue of the General Staff Guest House is not small, and it is a professional place specially used to hold such a national meeting.

As soon as Song Wencong and others entered the venue, almost everywhere they could see were the display materials of the design plans of the brother units. The venue was surrounded by aircraft schematic diagrams and various design data, and the aircraft models and wall charts were stained with experts and leaders, who were excitedly commenting and discussing.

The name of the brother unit can be described as thunderous in the system, and Song Wencong immediately walked over urgently, wanting to have a sneak peek of their new annihilation plan.

He stood in front of the introduction materials of the new annihilation plan, but his expression was a little stunned after a while. The smile on his face froze before, replaced by a furrowed brow and a deep thought.

After the participants had a basic understanding of the new annihilation plan, the meeting officially began.

Ye Zhengda, deputy director of the Commission of Science, Technology and Industry for National Defense, stepped onto the podium and said straight to the point: "The new fighter is the third-generation fighter we want to develop, and its main air combat performance is better than that of the Jian-8II model, close to the F-16 of the United States, and superior to the MiG-23 of the Soviet Union. ”

Hearing his words, everyone below was both excited and a little worried about the tactical and technical indicators determined by the new annihilation.

Immediately after that, the brother units began to report on their new annihilation plan.

The preparation of the program was very sufficient, the introduction information was full of pictures and texts, the speaker's ideas were clear and expressive, combined with the explanation of the aircraft model, and it took more than two hours to talk.

It can be seen that the new warfighter program has spent a lot of effort on the designer, put forward a lot of new design concepts, learned from the research results of some advanced countries in the world today, and also realistically considered the reality faced by the domestic aviation industry.

However, with the intuition of many years of aircraft design and research, Song Wencong felt the essence of the new J-8 of his brother unit, and still did not get rid of the J-8.

It's not so much a new J-8+. How come their old units, after so many years, have not yet stepped out of the layout of the J-8, how can they adapt to the trend of the development of world fighters in the nineties?

If you do it like this, you are just following the old path of Jianjiu. On the basis of the Jian-8, how can we build an aircraft that will not lag behind the world in the next 10 or 20 years? Only by jumping out of the old road of learning and imitation and building an advanced fighter truly designed by the Chinese can we achieve national defense independence and surpass the world's advanced fighters.

With such contemplation, Song Wencong carefully studied the design plan of the brother unit inside and out in his heart.

Only by knowing oneself and knowing one's opponent can one not be defeated.

On the third day, the meeting continued. To the surprise of brother units and many expert leaders, the host actually ordered Song Wencong to speak on behalf of the 611 Institute.

"For leaders and experts, the meeting gave us a temporary opportunity to speak. We did not prepare adequately, and here I apologize. ”

Song Wencong, who was in his fifties, stepped onto the podium and tried his best to keep himself calm: "For the development of the new annihilation, Deputy Director Ye has clearly put forward tactical and technical indicators, and I think this is the most basic goal that we must achieve. Otherwise, the new annihilation we have made will be of strategic significance......"

Song Wencong's first words on the stage made the faces of the brother units change color.

The new plan of the brother unit is based on the level of the domestic aviation industry. On the basis of the Jian-8 fighter, a considerable number of improvements have been made, which has indeed made great progress in the technical and tactical capabilities of the fighter.

But then again, the second-generation aircraft is no matter how much it is improved, after all, it is still a second-generation aircraft.

At the meeting, Deputy Director Ye made it clear that what he wanted was a third-generation aircraft and an advanced fighter that could confront international fighters.

The foundation of J-8 has no way to meet this requirement.

Song Wencong was like the little boy who exposed the emperor's new clothes, and suddenly pierced the atmosphere that the brother unit was trying to create.

If the Air Force's demand for third-generation aircraft cannot be satisfied, how can the state's strategy of formulating a new destroyer be realized just by tinkering with the second-generation aircraft? What is the significance of the existence of the new destroyer of the second-generation aircraft?

It is not a new J-1 of the third generation aircraft, and it has no meaning at all.

Song Wencong seized the opportunity and began to sell his views on the third-generation aircraft: "In recent years, judging from the local wars that have occurred in the world, it is no longer the situation when we fought with the US military on the Korean battlefield. The concept of modern warfare has changed substantially. First of all, we must understand what is war under the conditions of modern science and technology, how various types of aircraft conduct air combat, and what kind of weapons are used? Modern aircraft radars must not catch several targets at the same time, and bombs are submunitions and bombs. As soon as you fly together, people will know about it, and you have to track it, it can set false targets, and it can interfere with you......"

After stating his views on modern warfare, Song Wencong began to sum up the performance of the third-generation aircraft he envisioned: "So the new J we built must be fought at angular speed and be flexible. The overload should be large, the turning radius should be small, and the pilot should be able to maneuver easily. ”

……

Song Wencong's plan for the new annihilation made the higher-level leaders shine, and the plan of tailless + front wing was only adopted on the Swedish Saab 37.

The so-called tailless + front wing is actually a canard wing scheme. If purely from this point of view, the J-10 is indeed quite similar to the Saab-37.

This is also the reason why many people later accused Jian-10 of plagiarism, but in fact, Song Wencong's plan came from the dismounted Jian-9 fighter.

Since 1970, the accumulation of more than ten years of experience in the Jian-9 fighter is the reason why Song Wencong dared to boldly adopt static instability and canard wings on the new J-9.

And in the seventies, the Swedish Saab 37 had not yet come out. In a closed country, we will not be able to obtain any information.

In terms of the study of canard wing layout, China started very early. However, Song Wencong was still inevitably questioned by the experts attending the meeting.

The static instability of canard wings is a very difficult technology, can China achieve self-digestion and research and development? Once the static instability cannot be completed, what is the countermeasure?

The important question is whether Song Wencong can come up with a theoretical basis and experimental data that convince the experts and leaders attending the meeting. In this kind of debate, all the relationships, forces, and levels are imaginary, and what really plays a decisive role is the attitude toward science and the rigor of objective data.

At this time, the data and information accumulated by the 611 Institute in the past few years played a decisive role.

In the spare time of the past few days of attending the conference, in order to make the canard layout aircraft scheme have an intuitive effect, Song Wencong and everyone drew a pattern and made a model of the aircraft.

In the borrowed small carpentry room, they used grinding wheels, files, sandpaper and toothpaste – yes, you read that right, in the absence of abrasives, Song Wencong wittily used toothpaste to polish the model airplane.

It took two nights for a model airplane made of plexiglass to be created.

The things in the king's imagination and on the pattern have become physical models, and Song Wencong can't put them down.

Now, he brought the model to the jury.

In the face of the doubts of experts and leaders, Song Wencong only had a few slides and dry language in his hands, which dwarfed the complete materials prepared by the brother units.

At this moment, Xie Guang, who was sitting in the front row, saw Song Wencong gesturing with his hand on it, and he hurriedly handed over the plexiglass airplane model placed in his hand.

Models are obviously much more convincing than diagrams and language. Explain according to the physical model, which is obviously more intuitive and clearer.

Song Wencong held the model in his hand, and just after saying two sentences, he suddenly found a problem.

The model is too small for the person behind to see clearly.

At this moment, he saw a projector with a gelatin sheet on the table, and the pillar of light was visibly shining on the projection screen. With an idea, he pulled the model straight from the stand and put it on the projector!

This fully transparent plexiglass model of the airplane is projected on the curtain behind it - good guys, the plane looks like a fierce fighter jet, majestically passing through the sea of clouds and mist!

In an instant, the venue burst into warm applause.

A small model of a glass airplane that saved the fate of a generation of classic fighters.

Although Song Wencong's explanation was short, it was more touching than the introduction of the brother unit for a whole day. The static and unstable layout, the belly air intake and the four-degree redundant telex can be said to be an extremely bold attempt in China at that time.

In general, there is an unwritten international convention. If the research and development of a new aircraft is based on the previous generation of fighters, 30% of the spare parts are changed, the success rate is relatively high.

But the J-10 has so much innovation that 60% of its spare parts need to be developed from scratch. It is the first Chinese aircraft to jump out of the Soviet-style fighter mode, and it is also different from the American fighter.

Project No. 10 is a process in which the Chinese have gone their own way and others have no way out.

Hu Wenhai looked at the note in his hand that had Tu Jida's message, and looked at the familiar and unfamiliar name on it, and couldn't help but feel a little excited.
