In the research and development process of fighters, full-scale prototypes are a must, even if there are already advanced computer simulations, full-scale prototypes have their unique charm.

The drawings are always on the drawings, and there will be no visual sense of the real fighter, especially for ordinary people, looking at the drawings, there is no feeling, only when looking at the real machine, there will be that immersive feeling.

Now, they need to build a full-size model to let the Air Force take a look, the advanced nature of this fighter is beyond doubt, although the appearance of the Su-27 is very beautiful, but the shape of our J-10 fighter is absolutely unambiguous, this fighter adopts a canard layout, it is a trend of this era, look at Europe, the French study Rafale, Britain and other countries study the Typhoon, and Sweden's Gripen fighter, are designed according to the canard layout, when this fighter is majestically displayed in front of them, They will definitely be satisfied.

Of course, in addition to showing to the outside world, the full-size model, more importantly, for your own use, to create such a one-to-one model, is definitely not only the same on the outside, but also in accordance with the actual design of each part, so that you can test whether there is a problem with your own design, and whether there will be any unexpected situations when assembling, for example, the position of the screws designed here, the result is not able to be installed at all.

Even, some parts that have been developed can be directly installed for actual inspection, and various operations such as compatibility, adaptability, accessibility, reliability and maintenance can be coordinated.

Although the model can be fake, however, the various positions on the model, interfaces, etc., are made according to the actual one, so as to be able to test whether the design is reasonable, so it is absolutely not possible to directly enlarge the plexiglass model, the interior must be comprehensive, and even the cable must be simulated with a string, completely in accordance with the specific location.

"However, many of our subsystems have not yet been developed." Hearing Song Lao's words, Ma Haitao said, it is not yet to the point of building a prototype.

"If not, we will replace it with a box for the time being, in short, we must knock out our prototype as soon as possible and invite the personnel of the Air Force to visit." Song Lao said.

This is not to fool the Air Force, but a last resort, we must pass this model, give them confidence, and then explain, in order to win enough support, if there are more and more generals in the Air Force who like to buy a few more Su-27s, then there may be really no hope for their side.

If this is the case, the experience and team of independent positive research and development that have been accumulated in China will be hit hard.

After all, until now, the research and development of domestic military aircraft, mainly surveying and mapping, has not really been independently developed.

What's wrong with that?

It's okay to follow the cat and the tiger, but you can't improve it yourself.

Among them, there is an episode, when surveying and mapping a certain part, it was found that there was a piece of soap inside, the use of this piece of soap, the technicians had different opinions, some said that it was for lubrication, some said it was a counterweight, but what it was for, no one knew, and in order not to have problems, for the sake of insurance, therefore, all their own imitation equipment, also concocted in the same way, put a piece of soap in it, and then, more than ten years have passed, finally have the opportunity to ask people, why put soap in it?

The answer given by the other party was very simple, I washed my hands and put it away!

This is definitely not a joke, it is a real thing, if it is not developed by yourself, then you don't know the design ideas and principles of others, you can only copy, dare not have any changes, only self-research, everything is your own, how to change, how to change.

The current J-10 is an attempt, if this attempt stops, then later...

Song Lao didn't dare to think about what the situation would be in the future, what he needed most now was Tu Lao's indomitable spirit, no matter what difficulties he encountered, he had to move forward, move forward, and go all the way to the other side of victory!

The time was very short, Qin Feng sent Song Lao and the others to the car, and then returned to his residence, he still had one more thing, he didn't ask Song Lao, he said that he would go abroad for training, but then there was no follow-up.

Think about it, if you really decide to buy fighters from abroad, and you have to give up your own research and development, then there is no need to train pilots, of course, this situation will never appear, because Qin Feng believes that the superiors, the old leaders, will definitely not be short-sighted, they will definitely realize the importance of self-development, after all, just by buying, you can't buy the modernization of national defense.

In fact, since the founding of the People's Republic of China, it has attached great importance to this, no matter what you buy, it is not just to buy it, buy a part, you must introduce technology production, not to mention other industries, take the aviation industry as an example, Spey engine, buy an engine, to introduce technology, No. 8 bomb and A bomb, after buying a batch, it is also the introduction of technology, after all, the motherland is a big country, funds are also very lacking, relying on buying alone, there is not so much money at all, you must be able to produce your own, I didn't buy the Mirage 2000 back then, also because the French didn't let go of their mouths and didn't export technology.

Now, if the Air Force wants to buy the Su-27, it will not buy it all at once, and it will definitely have to introduce technology and produce it itself, so as to prevent being controlled by others in some cases.

Just look at Iran, the Tomcat fighters they bought back then made many people envious, and now, with the sanctions of the United States, their fighters have a fairly small intact rate, and they even have to tear down the east wall to make up the west wall, and use some planes to donate organs.

Of course, even if the technology is introduced, the person will not tell him how to design it, so it is best to do it yourself.

Qin Feng sighed, as soon as he stepped into the room, he saw the person sitting inside.

"You're back, boy? Old Song, they must be very anxious, right? It's time to put some pressure on them, there is pressure, there is motivation, our Air Force, still waiting for their fighters. "General Lin knows everything!

"Our Air Force, will we not give up J-10?" Qin Feng asked happily.

"Of course not, how is that possible! The Air Force has been waiting. General Lin said.

The Air Force likes the Su-27 and can't wait, but at the same time, the Air Force also knows that the number of heavy fighters purchased from outside, even if they are produced by themselves, cannot be too much, and the size of the Air Force is too huge, and there must be a medium-sized aircraft like the J-10.
