Jiang Yanhai's answer was very simple. He did not hide these technical ideas, because Jiang Yanhai's experience in subsequent engine series expansion is not as good as these old professors and the entire team led by the other party.

Secondly, he prefers to focus on combat instead of research.

If it weren't for these technologies to increase the overall scientific and technological strength of the entire country, Jiang Yanhai would not be willing to do this. You think he would.

"Okay, you said so, and I will be responsible for the subsequent expansion of the series." Professor Qian also agreed, and the WS series is also finalized, but in the long run, it is obvious that Jiang Yanhai is more developed here. Potential, it is necessary to know that a kind of engine can have both low-to-low-altitude low-speed and high-altitude high-speed performance at the same time.

This is very difficult.

Conventional turbojet engines are difficult to achieve such high speeds at high altitudes and high speeds, because when a certain speed threshold is reached, the air compressor of the turbojet engine is useless, or not very effective.

Bombers such as the XB70 that the United States has experimented with use ramjet engines at high altitudes.

And Jiang Yanhai's brand-new design may be the direction of future engine development. Of course, they should mainly study this direction.

"However, in terms of overall design, we will definitely communicate with you at that time. After all, you designed the entire engine. You obviously have a better understanding of this engine." Professor Qian said seriously.

"No problem." Jiang Yanhai also nodded.

"There is also a follow-up upgrade plan for the Phantom, haven't you already considered it? Remember to communicate with us." Liu Lao also added.

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

"Hahaha, don't worry, it won't be too far away." Old Liu also smiled directly, "By the way, let me know. If nothing happens, the Phantom will adjust some details. Completely finalized."

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

"All the tests that should be done have been done. At present, there are no major problems with the first and second test aircraft. All the data show perfect, and the engine test has not stopped until now. With so many engines tested at the same time, the test data has been more than 20,000 hours, and all the data shows perfect, why not finalize the model?" Liu Lao asked rhetorically.

"Jiang boy, I know what you are thinking. You think our previous fighters took so long to finalize their design. This time is 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 just set it up. The length of the set-up time is not important. These data show that even if we extend the set-up time to several years, the actual added performance is limited."

"Of course, if the upgrade standard you gave over there can be completed in a short period of time, it will be fine at a later date. Anyway, now we have J20, and the Phantom is a little bit later, so you can directly follow the more advanced version. "

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

"Mainly related to electronic systems." Jiang Yanhai has seen a full set of Phantom design drawings. All the designs inside are almost perfect. Of course, the performance is abnormal. However, many abnormal performances have more requirements for electronics and radar. 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, the domestic technology can be said to be the world's top, but in other electronic aspects, there are still some. Gap.

Jiang Yanhai held back it. In fact, what he wanted to say was that he also designed the Phantom’s electronic equipment. What is the concept of the full set of drawings? It's the same thing as the full set of drawings for that engine.

All the important materials and drawings of important designs are all in it, so there are naturally also designs for those electronic products.

Jiang Yanhai felt that he still had to stop speaking out, and waited for the later to speak slowly.

In fact, the design is different from what you can make.

But at the very least, if the design is done, you will have a direction when you want to make it.

Just like domestic infrastructure construction, our infrastructure construction used to be, we look at what tools we have in our hands, and we use these tools to find ways to complete infrastructure construction. The Qinghai-Tibet Railway was completed gradually in this way.

But now? Now, we will produce whatever tools we need! You don’t need to have any tools or tools like before.

This is a major advancement in technology! Therefore, as long as you design it, you can think of ways to design and produce in construction.

This is the true foundation of a big country.

Therefore, despite the fact that many industries in the United States seem to be sluggish now, and the industrial system is incomplete, but the foundation is there. If they are given time, they can quickly restore the entire industrial system.

But you are like the Germanic tanks of the European Union and the Gallic chickens. If they want to create a full industrial system, it is almost impossible, although they are also powerful countries!

Of course, it is also possible for the entire European Union to unite to create an entire industrial system.

Chatting with Lao Liu ~lightnovelpub.net~ while eating, in fact, these old professors have very little appetite, Li Ruobai eats more than them, and let alone Jiang Yanhai, strong physical fitness needs. It is a huge energy supplement.

Therefore, Jiang Yanhai's appetite has always been not small, and the old professor at the last table was smiling and watching the two young girls, Jiang Yanhai and Li Ruobai, eating, uh...no, it was a young man and a young girl eating.

In the end, all that was left was watching Jiang Yanhai eating by himself.

And Professor Li asked with a kind face next to him: "What are you going to eat? I'll give you a clip."

If you change someone else, you probably won’t be able to eat it, but Jiang Yanhai has no worries about this. Isn’t it a waste of the food at this table if you don’t eat it? So even if a circle of old professors watched with a smile, he was very happy to eat.

Even Li Ruobai is a little embarrassed, but he can't help but let him eat it. Forget it, let my Haige eat it. Otherwise, he can't be hungry.

After dinner, it was actually Jiang Ling meeting with the old professors, so as not to prevent these old professors from not knowing, wouldn't it be embarrassing to expose?
