What should I do if the model is gone?

If there was a model, it would be the most spectacular, and now, without the model, it would be the most ordinary way!

Song Lao looked at everyone and said, "Quick, go to the brother unit immediately, borrow a few gelatins, let's draw our basic data and graphics on them, and tomorrow, let's use these gelatins to report." ”

In this era, the projector is still one of the most common tools, by enlarging the gelatin and projecting it to let many people see, which is the best way to report.

And now, that's all that's been done.

"I remember all the data." Qin Feng said: "Let's do it immediately!" ”

Although he only stayed in the 611 Institute for two days a week, and even because the project was very urgent, sometimes he just went around for a turn, but Qin Feng remembered some data about the new Jelf pre-research very clearly.

Now, I can only rely on my brain to recall all the data, draw it on the gelatin, and prepare for tomorrow's report.

It's like catching ducks on the shelves.

I really don't know how that model of mine fell, how could I be so careless! Qin Feng also secretly blamed himself in his heart.

It was a sleepless night, everyone was seriously recalling, the drawings, the data was not for nothing, it was calculated repeatedly.

What engine to use, aerodynamic layout, determines how big the maximum speed is, climb rate, etc., these data need to be calculated to know, now, can only be written silently by memory, if you recalculate, even if you have a slide rule at hand, it will be too late.

In the middle of the night, everyone went back to sleep, and a few hours later, they got up.

It was on such an ordinary day that the major event that went down in the annals of the entire domestic aviation history began.

The morning sun rises in the east, and the winter in the north is cold, and the sun is somewhat whitish and shining on the earth.

The snow had not yet melted, and the north wind was whistling and blowing on the ridge of the house, making a whining sound, as if calling for something.

Winter is coming to an end, and spring is coming!

The venue is lively, when Song Lao took a few people and entered the venue, you can see that the venue has been carefully arranged, and there are huge wall charts on the walls around the venue, which is the J-13 fighter that the big brother unit has made!

At this time, there was no computer drawing, no computer deliberately rendered renderings, and these wall charts hanging on the wall at this time were drawn by the draftsmen with one stroke.

You can clearly see its overall structure, just like a small F-16, it has edge wings, which is a new trend in the aviation industry, through the edge bar to pull the vortex, the use of the vortex to effectively improve the performance of the fighter with a high angle of attack.

After all, according to the requirements, the maneuverability required by the J-13 is quite high, which can only be achieved with this airfoil.

At the same time, in terms of air intake, the two layout methods of organic abdominal air intake and side air intake have not yet been finalized, so there are wall charts to show both forms.

Perhaps, after today's discussion, a group of experts will decide which way to use.

The bright red words on the wings are the most exciting, this will be the most advanced fighter project in China!

At the same time, in the center of the conference hall, there is also a table, on which a large-scale model has been arranged, more than two meters long, so that everyone can see clearly, this carefully crafted wooden model, showing everything clearly.

On the side of the model, there is also a nameplate detailing the basic technical specifications of this aircraft.

At this point, the meeting has not officially begun, and everyone is either looking at the flip chart or looking at this model.

J-13 has been carried out for ten years one after another, and Song Lao has always heard about this project, and now, looking at the airfoil has followed the trend of the times, and the overall design is still exquisite, at this time his heart is also excited, and he is proud of this project of the big brother unit.

However, when he got in and saw some of the parameters on the nameplate next to the plane, he couldn't help but start frowning.

"Old Song, what do you think of our project?" Just then, a voice came to my ear.

When he was in the 601 Institute, Song Lao was the director of the pneumatic room, and after he left, the pneumatic room was in charge of the old comrade who spoke beside him.

Director Fang, has been working with Mr. Gu on advanced aerodynamic layout, this J-13 fighter, can be regarded as the crystallization of their hard work, now, it is about to enter the final review stage, transferred to the development sequence, Director Fang is very excited.

Hearing his old friend's words, Song Lao didn't say anything, just laughed dryly, and then slowly returned to his seat.

"How? If you have different ideas, you can't communicate at all, right? At this moment, Qin Feng on the side spoke.

Qin Feng went to Shenyang, and a group of experts in Shenyang strongly invited Qin Feng to participate in the J-13 project, but Qin Feng finally tried his best and almost fled back to Chengdu, which almost became a joke in the aviation industry.

Even Song Lao actually didn't understand it, but now, looking at the introduction of this project, Song Lao finally understood.

In terms of fighter design concept, there are huge differences, this J-13 fighter, although it looks very powerful, but, because of the problem of design concept, it has congenital defects, if this finalization meeting, really let the J-13 project go on, it will make the Air Force lose valuable development opportunities, will take a big detour!

Originally, Song Lao did not plan to compete with the big brother unit, after all, this meeting is the J-13 design and finalization meeting, it can be said that the country convened relevant units to participate in this meeting, is to promote the J-13 project, but, now, Song Lao knows that he must fight and replace this J-13 project with his own new J-13 project.

Even if it fails, at today's meeting, we must explain to a group of experts, including the leaders of the Air Force, what the future air war should look like, and we must not take a detour because of the direction issue!

Song Lao made up his mind.

The meeting has finally begun.

The person in charge of presiding over the meeting was Deputy Director Ye of the National Defense Industry Office, who looked at the hundreds of people attending the meeting with a solemn face: "All comrades know that the goal of our meeting is to review the plan of the third-generation fighter, the performance of this fighter is higher than the current J-8, close to the American F-16, superior to the Soviet MiG-23, and can truly compete with the aircraft being equipped abroad, as the main combat aircraft of the Air Force in the nineties." ”

This is the historical mission entrusted by the times to Xinji, and this requirement must be met.
