Jiang Yanhai replied very simply, he did not hide the idea of these technologies, because Jiang Yanhai's experience in the expansion of the follow-up engine series was not as good as that of these old professors and the entire team led by the other party.

Secondly, he prefers to focus on his own combat rather than research.

If it weren't for the fact that these technologies could increase the overall scientific and technological strength of the entire country, Jiang Yanhai would be reluctant to engage in these, do you think he would be willing?

"Okay, you said that, then I'll take care of the rest of the expansion." Professor Qian also simply agreed, and the WS series was also finalized, but in the long run, it is obvious that Jiang Yanhai has more development potential, you must know that an engine can have both low-speed and high-altitude performance at low altitude.

This is a very difficult thing to do.

It is difficult for a conventional turbojet engine to reach such a high speed in terms of high altitude and high speed, because when a certain speed threshold is reached, the air compressor of the turbojet engine is useless, or it is not very useful.

Bombers such as the XB70, which the United States once experimented, use ramjet engines at high altitudes.

And Jiang Yanhai's brand-new design may be the direction of future engine development, of course, they have to focus on this direction.

"But in terms of overall design, we will definitely communicate with you at that time, after all, the entire engine was designed by you, and you obviously know more about this engine." Professor Qian said seriously.

"No problem." Jiang Yanhai also nodded.

"There's also the follow-up upgrade plan for the Phantom, haven't you already considered it? Don't forget to talk to us. Liu Lao also added.

"Don't worry, I'm still thinking about the moment when the Phantom can dominate the sky." Jiang Yanhai immediately said with a smile.

"Hahaha, don't worry, this won't be too far." Liu Lao also smiled directly, "By the way, I will inform you, if nothing else, the phantom will be completely finalized after making some adjustments in details." ”

"So fast?" Jiang Yanhai was a little surprised, you must know that since the first one was produced at the end of September, it has only been January, that is, 4 months, which is finalized?

"All the tests that should be done have been done, at present, the first and second test aircraft models have not had big problems, all the data are shown to be perfect, and the engine test has not stopped until now, so many engines are tested at the same time, the test data has been more than 20,000 hours, all the data shows perfect, why not finalize?" Liu Lao asked rhetorically.

"Jiang boy, I know what you're thinking, do you think that our previous fighter took so long to finalize, and this time it was so short, isn't it a bit unreliable?" Professor Li next to him asked with a smile.

Jiang Yanhai nodded, he really thought so.

"Boy, we all want to design it and set it directly, the length of training time is not important, these data show that even if we extend its training time to a few years, the actual increase in performance is limited."

"Of course, the upgrade standard you gave over there, if the upgrade can be completed in a short period of time, then it's nothing to finalize it later, anyway, now we have J20, and the Phantom is a little later, so you can go directly to the more advanced version."

"What are your main aspects of upgrading?" Liu Lao asked.

"It's mostly about electronic systems." Jiang Yanhai has seen a full set of phantom design drawings, all the designs in it are almost perfect, of course, the performance is also perverted, but many metamorphosis performance requirements for electronics and radar are relatively high.

"Then it is estimated that after you submit it, it will be difficult for us to research and produce." Liu Lao shook his head slightly, in terms of electronics, such as radar, domestic technology can be said to be the world's top, but there is still a gap in some other electronic aspects.

Jiang Yanhai couldn't help it, in fact, what he wanted to say was that he had also designed the phantom's electronic equipment, what was the concept of a full set of drawings? It's the same as the full set of drawings for that engine.

There are all the important materials and drawings of the important design, so the design of those electronic products is naturally there.

Jiang Yanhai felt that he still didn't want to say it, and he would say it slowly later.

In fact, the concept of designing it is still different from what you can make.

But at the very least, the design is out, and then you have a direction for what you want to manufacture.

Just like the infrastructure construction in China, our infrastructure construction used to be that we looked at what tools we had in hand, and we used these tools to find a way to complete the infrastructure construction, and this was how the Qinghai-Tibet Railway was completed step by step.

But what about now? Now, we produce whatever tools we need! There is no need to have any tools and use any tools like before.

That's a big step forward in technology! Therefore, as long as you design it, you can find a way to design and produce it in China.

This is the true essence of a great country.

So, don't look at the fact that many industries in the United States seem to be sluggish now, and the industrial system is not complete, but the background is there, and if they are given time, they can quickly restore the entire industrial system.

But you're like the Germanic chariot of the EU, the Gallic chickens, if they want to come up with a whole industrial system, it's almost impossible, even though they're also powerful countries!

Of course, it is also possible for the entire EU to come together to create an entire industrial system.

chatting with Liu Lao and eating at the same time, in fact, the amount of food of these old professors is very small, Li Ruobai eats more than them, and Jiang Yanhai not to mention, the strong physical fitness needs a huge amount of energy supplement.

So Jiang Yanhai's amount of food has always been not small, and the old professors at the last table all looked at Jiang Yanhai and Li Ruobai with a smile and two little girls eating, uh...... No, it's a young man and a little girl eating.

In the end, it was left to watch Jiang Yanhai eat alone.

Professor Li asked with a kind face, "What do you want to eat?" I'll give you the clip. ”

If this is estimated to be a different person, it is estimated that he will not be able to eat it, but Jiang Yanhai has no concerns in this regard, isn't it a waste not to eat the food on this table? So even if a circle of old professors looked at it with a smile, he was very happy to eat.

Even Li Ruobai is a little embarrassed, but he can't stop him from eating, forget it, let me eat Brother Hai, otherwise, it's not okay to starve Brother Hai.

After eating, in fact, Jiang Ling met with the old professors, lest these old professors don't know each other, wouldn't it be embarrassing to be exposed?
