Siheyuan: The Era of Struggle.

Chapter 236 Yang Ning talks about future fighters (please subscribe)

"With the development of missile technology, future fighter jets will definitely not pursue high altitude and high speed."

"Compared to missiles, fighter jets need humans to pilot them after all, and humans have a limit to what they can bear. The limit of what humans can bear is the limit of the height and speed of future fighter jets."

"Missiles do not have this limitation. With the development of technology, the speed and altitude of missiles will definitely far exceed those of fighter jets. Moreover, compared with fighter jets, the cost of missiles can be said to be very cheap."

"If fighter jets continue to pursue high altitude and high speed, they will become sitting ducks when facing missiles in the future."

"Isn't this impossible?" Director Nie was surprised when he heard Yang Ning's analysis. "Except for ballistic missiles, the maximum speed of all missiles has just exceeded Mach 21. The speed and height of the big brother MiG- far exceed all current air defense missiles."

"Missile technology is developing, and aircraft technology cannot remain stagnant. Moreover, the flexibility of aircraft is far beyond the reach of missiles."

"Although I don't want to admit it, before there is a major breakthrough in guidance technology and electronic technology, the probability of shooting down a fighter jet with a missile is indeed low."

After hearing what Director Nie said, Mr. Qian looked at Yang Ning thoughtfully and said.

"Is this probably why you are so anxious to develop electronic technology?"

Director Nie now understood why Yang Ning had been so eager to develop the lithography machine. Combined with Yang Ning's analysis just now, everything made sense.

Because only when electronic technology makes breakthroughs can our computer technology, guidance technology, radar technology, remote control technology and other fields related to electronic technology continue to develop.

"That's true. If integrated circuits can be produced, then in the future only a thumb-sized integrated circuit would be needed to greatly improve the guidance capability of missiles."

"And after the use of integrated circuits, the performance of both radar and computers will be further improved. This way, when facing high-altitude and high-speed fighter jets, our chances of shooting them down will be greatly increased."

"Just think about it. Once a high-altitude, high-speed aircraft enters our airspace, it will be detected by our radar, and the system's computer will quickly calculate its distance and speed, and then control several anti-aircraft missiles with a speed of up to Mach 4 to attack it. What kind of scene would that be?"

Following Yang Ning's description, Director Nie and Mr. Qian thought about what the fighter pilot might have done if he encountered that situation. He could only pray for God's protection.

Otherwise, no matter who it is, faced with such a situation, they will inevitably be shot down.

"So according to what you said, what is the future development trend of fighter jets?"

If it is true as Yang Ning said, that high-altitude, high-speed fighter jets will eventually die, then does that mean fighter jets will have to exit the stage of history?

Even Mr. Qian, who has always opposed us following Big Brother and Eagle Sauce in the field of fighter jets, couldn't help but worry about the development of fighter jets.

"According to my vision, the development trend of future fighter jets is high stealth, high maneuverability, high posture perception and supersonic cruise."

What Yang Ning said is the standard of the fifth-generation aircraft. Although our technology cannot reach it now, it does provide a correct direction for the development of our future fighter jets.

"In my opinion, the way of future fighter jets is to use low altitude and high speed to break through the enemy's radar detection, and then use high posture control to evade the enemy's air defense firepower, and finally strike the enemy's key targets."

"Supersonic cruise can also maximize the fighter's survival rate and combat efficiency."

"Hiss~" After hearing Yang Ning's vision for future fighter jets, both Mr. Qian and Director Nie couldn't help but take a breath. Isn't this standard too high?
Not to mention high maneuverability, they can still understand that, but if they want their fighter jets to achieve supersonic cruise, let alone us, even the most advanced fighter jets of Big Brother Eagle cannot meet this requirement.

Not to mention stealth technology and high-profile perception, which they had never heard of.

"Can you tell me in detail what technologies we need to overcome if we want to develop such a fighter?"

As a leader in our scientific research field, Director Nie is very interested in things that have guiding significance for our future science and technology.

"If you want to study this kind of fighter, you must first consider the fuselage material. Otherwise, the fuselage will be torn apart during high-G maneuvers."

"Engine technology cannot be ignored either. If you want a fighter jet to meet that requirement, the engine requirements are very high, and turbojet engines are not enough. We must switch to turbofan engines that are more fuel efficient and have greater thrust."

"If you want fighter jets to achieve high-level awareness, then you cannot do without the development of electronic technology and the fly-by-wire control system used on the CF105 of Maple Leaf Country."

"As for the final high stealth, we need to start with the fuselage layout design and stealth materials."

When Yang Ning finished speaking, Director Nie only understood a little bit, while Mr. Qian lowered his head and thought for a while, then asked Yang Ning: "The stealth technology you mentioned here should only reduce the reaction area of the fighter jet on the radar, right?"

"Of course. If fighter jets want optical stealth, that technology is too far away from us and unrealistic." Yang Ning replied with a smile.

"We will slowly study the stealth materials first, but you mentioned that the fuselage layout can also reduce the fighter's radar response area. What is the principle behind this?"

It will take time to make a breakthrough in materials science, but the fuselage layout can also reduce the radar response area of the fighter. This is the first time that both Director Nie and Mr. Qian have heard of it.

"This is what we need..." Yang Ning was just about to say, isn't this the theory in the paper "Edge Wave Behavior in Physical Diffraction Theory" by the big brother mathematician Ufimotchev?

However, he immediately realized that this theory was proposed by Ufimchev in 64, and it is only 58 now, which means that the theory has not yet been proposed.

But that's not necessarily the case. The design principles of the Horten 2-29 fighter built by Hans during World War II are the same principles that Ufimchev talked about in "Edge Wave Behavior in the Physical Theory of Diffraction". The birth of this fighter was almost 20 years earlier than "Edge Wave Behavior in the Physical Theory of Diffraction".

This fighter jet is also the ancestor of the Eagle Sauce B2, half a century earlier than the Eagle Sauce B2.

Yang Ning thought about it and felt that this matter was extremely outrageous.

However, since "Edge Wave Behavior in Physical Diffraction Theory" has not been published yet, but with the Horten 2-29 fighter in front, Yang Ning did not hesitate to take the theory in this paper for himself.

So he explained: "During World War II, Hans produced a very strange fighter, the Horten 2-29, which used a tailless flying wing fuselage design." "When I learned about this fighter, I thought it was very strange and completely contrary to the mainstream thinking of fighter design at the time."

"I was thinking that with Hans's scientific and technological and industrial level at the time, it couldn't be that he designed this fighter just for fun, right?"

"So I calculated the data of the fuselage layout of this fighter, and then combined it with the working principle of the radar, I found an interesting phenomenon."

"Because of the design of the fuselage edge of this fighter, the radar has almost no reaction when facing this fighter."

"After calculations, I found that the intensity of an object's reflection of radar electromagnetic waves has nothing to do with the size of the object, but is proportional to the edge layout."

Then Yang Ning asked Director Nie for a piece of paper and drew on the paper how to calculate the radar reflection surface of the aircraft surface and edges.

Mr. Qian carefully looked at the schematic diagram drawn by Yang Ning, pondered for a long time, and then took a deep breath: "This is incredible. This development will completely change the future development pattern of fighter jets."

Director Nie, as our leader in the field of science and technology and also a military strategist, instantly understood the important role of Yang Ning's theory in the military field.

So he looked at Yang Ning with a serious expression and asked, "Who else have you told this theory to?"

"That's it. If you hadn't asked me about the future development trend of fighter jets, I would have almost forgotten this theory. Now in our country, only three of us know about it."

"In our country, you mean people from other countries have also discovered this theory?"

Director Nie's expression became even more serious after hearing what Yang Ning said. If foreign countries had already started researching stealth aircraft, then we would be far behind.

"Not sure, but even if other countries haven't discovered this phenomenon yet, this theory won't be hidden for long."

"Don't forget, during World War II, all of Hans's technology and scientists were eventually divided up by Eagle Sauce and Big Brother."

"Hans was able to develop the Horten 2-29 fighter during World War II. I'm afraid they had discovered this phenomenon a long time ago. No one knows whether Big Brother and Eagle Sauce have obtained research data in this regard from Hans?"

Yang Ning wasn't sure whether Eagle Sauce and Big Brother had noticed this phenomenon.

"Indeed, even if Big Brother or the Eagle Sauce have obtained this theory, they are unlikely to make it public. After all, this theory is too important for the future development of aviation."

"But now we have this theory, it's not too late!"

Director Nie smiled at first, then looked at Yang Ning and said sternly: "You are also fooling around. You didn't report such an important theory as soon as you found it."

"Hehe, I just thought this phenomenon was interesting at first, so I didn't think much about it." Yang Ning smiled embarrassedly and explained hastily: "It was when I was thinking about the future development of fighter jets recently that I realized the importance of this theory."

"Okay, that's it for now. Remember to organize this theory when you go back. It will be kept as our internal confidential information in the future."

"I understand." Yang Ning nodded and said.

"By the way, Yang Ning, how is your project at the Institute of Optics going? I've encountered some problems with my research here, and the computing center is mostly occupied by the Institute of Atomic Research. If you have time, please help us process the data."

Mr. Qian then remembered why he came to see Director Nie today. He was so focused on listening to Yang Ning talk about the future development of fighter jets that he almost forgot about the business.

"Just send the information you need to process directly to the data processing institute tomorrow. I'll be there in the first half of the day."

Yang Ning looked at Mr. Qian in confusion and wondered why he didn't send the information directly to the data processing institute, but went directly to Director Nie.

"You misunderstood. In the next period of time, our research project will have a large amount of data to process every day. If it cannot be processed in time, it will delay the research progress. Besides, it is not convenient for us to send the data back to Sijiu City every day, so I would like to ask you to come to our side."

This time, Mr. Qian and his team are researching a solid-fuel medium-range missile with a range of more than 1 kilometers. Therefore, the single-stage design of Dongfeng can no longer meet the requirements of this missile, and multi-stage propulsion is required to enable the missile to reach its designed range.

Moreover, we are now studying solid-state missiles, and the implications of this are very intriguing.

If Yang Ning remembers correctly, Chief Engineer Huang should have already started working at this time, right?
"Hiss~" After figuring out the connection here, Yang Ning couldn't help but take a breath, and then he curiously asked Director Nie: "Has our Big Black Fish project been researched yet?"

"How did you know?" Director Nie asked subconsciously, then he reacted and looked at Yang Ning seriously and said, "This project is still under construction, and not many people know about it. Since you have already guessed it, don't spread it around."

"But how did you guess it?" Director Nie and Mr. Qian asked curiously.

"The only ship that can allow us to abandon the research experience we have accumulated and the easier research of liquid missiles, and instead research solid missiles, which we have no experience in and are more complicated, is probably the Blackfish. After all, the Blackfish can only be equipped with solid missiles."

"But are we planning to study strategic nuclear submarines and attack nuclear submarines together?"

"You are such a quick thinker that you can even make that connection." Director Nie said with a smile.

"We do plan to study the two types of nuclear submarines together. After all, the two projects have many similarities. Studying them together can not only save a lot of time and energy, but also facilitate confidentiality."

"But you don't have to worry. This is just the preparation stage. It's not time for you to take action yet."

"But speaking of which, how is the progress of the lithography machine project?"

"Haha~" Yang Ning smiled confidently: "Don't worry, I can definitely design it before my child is born."

"In fact, there is no need to rush Mr. Qian. If we can wait until the integrated circuit is produced, the accuracy of our missiles can be further improved. Now that the design is out, it will need to be modified by then."
