When I am reborn, I just want to be a top student

No one would have thought that a meeting on technology updates would develop to this point.

When Wang Dong mentioned radar, Chief Hu's face became extremely serious, completely losing his previous ease and comfort.

Even the leaders in the aerospace field are like this.

As one of the world's major powers, it is natural that China cannot be without ideas about the sixth-generation aircraft.

However, this is top secret and will never be leaked.

If a leak occurs, it will be a huge accident.

Wang Donglai's experience is clearly traceable, so there is no way he could be related to the leak.

But it is this that makes people feel shocked.

An outsider who doesn't understand these things can actually have such a deep understanding of the sixth-generation aircraft.

Chief Hu didn't know whether to say that Wang Donglai was gifted or that he was naturally intelligent.

Being able to become the head of the military, Chief Hu’s military capabilities must be strong and his theoretical knowledge is also excellent.

Therefore, when Wang Donglai mentioned some ideas about the sixth-generation aircraft, he quickly constructed a rough data structure in his mind.

It has to be admitted that even by strict military standards, Wang Donglai's plan must be given a very high evaluation.

After understanding this.

Chief Hu immediately interrupted Wang Donglai, suspended the meeting, and gave a look to several other leaders.

Afterwards, several leaders left the meeting room.

In another quieter meeting room, Chief Hu spoke up first, "I think today's matter needs to be kept confidential. I propose this as a committee member. Please raise your hands and vote."

When the other leaders heard Chief Hu's words, they were stunned at first.

Then, Deng Tao, deputy director of the space agency, said, "Director Hu, can I know the reason?"

Commander Hu glanced at the others, then nodded slowly and said, "Okay, let me tell you that the idea of ​​the sixth-generation aircraft mentioned by Academician Wang just now is not aimless. As a soldier, I will comment on the plan proposed by Academician Wang. I think this plan is very valuable and feasible."

"Is this reason enough?"

Deng Tao nodded slightly, not really surprised.

After just a moment, Deng Tao made a decision and said, "I agree!"

Soon, everyone else nodded in agreement.

A brief meeting ended and a very important decision was made.

When several leaders returned to the original meeting room, a staff member quickly took out a confidentiality agreement.

Chief Hu said to everyone seriously: "Comrades, the content of today's meeting is somewhat sensitive, and you need to sign this confidentiality agreement."

After hearing Chief Hu's words and looking at the confidentiality agreement in front of them, everyone turned their eyes to Wang Donglai.

Everyone is not a fool. They have all fought their way out of the single-plank bridge of the college entrance examination.

Therefore, it is natural to understand that this sudden confidentiality agreement is most likely related to what Wang Donglai just said.

Thinking of this, many people's eyes brightened.

The design of the sixth-generation aircraft is a huge project.

For many people, being able to participate in this project would be something they would scramble for.

No one refused to sign a confidentiality agreement.

Those who can appear here have been exposed to countless state secrets and have signed countless confidentiality agreements. They don’t care about this one at all.

After everyone signed the confidentiality agreement, a smile reappeared on Chief Hu's face, and he said to Wang Donglai, "Academician Wang, I'm sorry to interrupt you just now. I wonder if you have any ideas or thoughts about the sixth-generation aircraft."

"Now, everyone has signed a confidentiality agreement. I will record everything you said and submit it to the higher-ups for decision-making."

"So at this time, you can boldly speak your mind."

When Chief Hu said this, his tone was calm, but there was a hint of expectation in his eyes.

It was obvious that Chief Hu wanted to see if Wang Donglai had anything better or more advanced technology.

Wang Donglai naturally understood the meaning of Chief Hu's words.

He quickly organized his words in his mind and said, "Commander, actually, the reason why I am so aggressive in promoting the development of the sixth-generation aircraft is actually for another consideration."

"Everyone knows that I have another identity, that is, the founder of Galaxy Technology, so I am more sensitive to changes in the business market."

"We are now our largest foreign market, and everyone knows that."

“Since we joined the world market, our technology and markets have developed tremendously.”

"However, such rapid development cannot continue forever."

"I paid attention to some data, and through data analysis, I keenly realized that the bald eagle has created a huge trade deficit with us."

"Based on these data, I judge one thing, that we may have a trade dispute with the most powerful country in the world."

"Before, my inclusion in the Bald Eagle Economic Sanctions List was a sign that such things will only happen more and more in the future."

"It is for this reason that I think we should step up the development of the sixth-generation aircraft."

"It will be finalized within one year, deployed within three years, and officially put into service before 2020. This is the most appropriate time in my opinion."

When Chief Hu heard Wang Dong announce the schedule, he remained silent.

An academician who was listening nearby could not stand it any longer and immediately retorted, "Academician Wang, I think the time you set is totally unrealistic and unscientific." "Finalizing within one year and deploying within three years, this is simply a joke!"

"Let's start with the J-20 as an example. The design of the J-20 was proposed in the last century, but it was not officially presented at the military exhibition until this year."

"But even so, the J-20 still needs to be continuously updated and equipped with more advanced weapons technology."

“I believe everyone should be clear about this.”

"Just now, Academician Wang mentioned the sixth-generation aircraft. Some of the concepts are indeed very advanced, but at the same time, they are also technically difficult."

"Earlier, Academician Wang also said that the R&D investment for a fighter jet can be as low as tens of billions, or as high as hundreds of billions. With such a large-scale investment, there is no room for error."

“To finalize it within a year, in my opinion, is simply an impossible task!”

As the academician finished speaking, several other academicians nodded in agreement.

Even Deng Tao was prepared to give Wang Donglai some basic knowledge about the research and development of fighter jets.

However, before Deng Tao could say anything, Chief Hu took the lead and said, "Academician Wang, can I ask why you chose this time of one year?"

"In other words, where do you get the confidence that you can finalize it within a year?"

Wang Dong glanced at the academician who had spoken earlier, then at Deng Tao, and finally at Chief Hu.

The smile on his face did not diminish at all, and he said, "Then I will briefly explain it. If there is anything wrong with what I said, I hope everyone can give me some advice."

"The key to whether the sixth-generation fighter jet can be realized lies in weapons and engines. As for engines, I believe everyone is clear that they have always been the weak link in my country's aviation industry. There are many reasons for this, such as the late start of our basic disciplines, weak foundations, and few professional talents, etc. These need not be mentioned again."

"At present, the WS-10 engine we use cannot meet the J-20's super maneuverability and supersonic cruise requirements. Although I have not seen this, I can analyze it from various data."

"The fourth-generation WS-15 high-thrust engine indicates that my country's aviation engine technology has entered the ranks of the world's aviation engine powers, but it is not yet the most advanced."

"As someone who independently developed the Hercules engine, I feel I have the qualifications and confidence to say this. I think you all should have no objection, right?"

Wang Dong said this, looking around at everyone.

No one objected and everyone agreed.

"The engine of the sixth-generation aircraft is indeed a difficult problem, but that is for others, not for me."

"Then the next thing is weapons. In many people's impressions, the weapons carried by fighter jets are only those artillery shells, and there is nothing else."

"But I have a different opinion. The sixth-generation aircraft is a product that spans an era and is more advanced and scientific."

"I think the sixth-generation aircraft should be equipped with laser weapons. The killing principle of laser weapons is to ablate and destroy the aircraft's structure and optoelectronic devices. The aircraft shell is generally made of aluminum alloy with a melting point of 1500°C. The critical damage value is 1-10 kilowatts per square centimeter. The power density of a single pulse of a 100-kilowatt carbon dioxide laser within 5 kilometers is between 100 kilowatts and 10 megawatts per square centimeter."

"Assuming the airborne laser reaches a volume of one cubic meter and a weight of two tons, the output power can reach 2 kilowatts, which can destroy the aircraft skin within a range of 100 to 5 kilometers within one second."

"In addition, the optical lens of laser weapons can emit laser beams in all directions, and enemy aircraft can be brought into attack range without maneuvering flight, so the sixth-generation aircraft no longer needs close combat, and aircraft cannons and infrared-guided air-to-air missiles may disappear completely!"

"No, they will definitely disappear, because in front of laser weapons, they are completely useless and are just a burden."

"I know that some experts will talk about the error problem of laser weapons. The accuracy gap caused by projection optical components, optical coatings and jitter is about 200 microradians. At 100 kilometers, the error is 380 mm, and the spot diameter is 2760-10 mm. When the spot diameter increases from 20 kilometers to 20 kilometers, the power density decreases. When the distance increases to 3 kilometers, the irradiation time is about 5 to 10 seconds. If the target maneuvers, the irradiation may reach 20-100 seconds. A 4-kilowatt laser weapon irradiates for 60 seconds and requires 10 seconds of cooling. This greatly increases the heat dissipation requirements. Clouds, haze, and sandstorms will greatly reduce the range, so the effective attack distance of airborne laser weapons is only about kilometers."

"The sixth-generation aircraft still needs to carry medium- and long-range air-to-air missiles in its internal magazines. If an attack is launched at a distance of 100-150 kilometers, an air-to-air missile with a speed of Mach 4 will only take 100-160 seconds to hit the target. I believe our country should have had this kind of air-to-air missile a long time ago."

“可是六代机的空战探测距离会局限在5-20千米范围内，假设仅供战斗机以2马赫的飞行速度在20千米以3秒间隔发射4枚空空导弹，这需要9秒的时间。”

"It takes 12 seconds for the first missile to hit the target, and 5 seconds for the fourth missile to hit the target. In theory, during this time period, the fighter jet flies 6 kilometers forward and the distance between the two sides reaches 10 kilometers. The attacked sixth-generation aircraft uses airborne laser weapons to intercept air-to-air missiles. If it takes one second to destroy a missile, it takes 3 seconds to transfer the target, that is, 4 seconds, and it can intercept 9 air-to-air missiles launched within 4 seconds."

"An offensive fighter needs six air-to-air missiles to break through the interception of the defensive fighter. If the aircraft and the missile maintain the same course and do not need to change the target, 6 missiles are needed to break through the interception. If the offensive fighter approaches the irradiation range of the airborne laser weapon, the two sides will compete in the lethality and protection capabilities of the laser. The party that irradiates first may directly destroy the opponent's optoelectronic tracking laser aiming and launching equipment, but if the irradiation timing is too early and the power density is not enough to destroy the opponent before the laser overheats and shuts down, the opponent may take the opportunity to irradiate when the laser cools down and win."

"In short, the sixth-generation aircraft must solve the contradiction between laser power and shortened cooling time and weight and size."

"There are several solutions to this problem, and I won't go into details here."

"In addition, the sixth-generation aircraft I envision will also eliminate the large protruding cockpit and replace it with a semi-enclosed or fully enclosed cockpit with an anti-laser coating. The cockpit will also abandon the flat-panel display. All information will be provided by AR helmets and networked avionics systems. The system will automatically communicate with other fighters, automatically capture and identify enemies, and the pilot will even only need to control the aircraft through virtual reality equipment."

"Of course, it is very difficult to do this."

"However, the sixth-generation aircraft is currently the most advanced fighter in the world and still exists on the drawings of various countries."

"You should all be able to see and feel how fast science and technology are developing right now."

"The design concept of the sixth-generation aircraft must be forward-looking. It should lead the development of other technologies, rather than wait for other technologies to achieve breakthroughs before moving them to aircraft."

"To do so would be putting the cart before the horse. The sixth-generation aircraft is a national treasure and a decisive strategic weapon for safeguarding national security."

"For a weapon of this status, we cannot attach too much importance to it!"

"So, the earlier we start research and development and produce it, the greater the benefits we will get."

"The above are my design concepts and ideas. Please correct me!"

After saying that, Wang Donglai sat down by himself.

After Wang Dong finished speaking, everyone present fell into deep thought.

If it was just boasting, everyone would have jumped out to refute it long ago.

But Wang Donglai is not like that. He has a complete design concept for the sixth-generation aircraft, which surpasses many people.

Secondly, Wang Donglai really understands technology. He knows the research and development information of some key technologies, as well as the shortcomings of some technologies, and can provide corresponding solutions.

The combination of these factors makes Wang Donglai's plan more feasible.

That's why everyone present fell into deep thought.

Even leaders like Chief Hu were hesitant. (End of this chapter)
