Siheyuan: I eat melons while doing scientific research

Chapter 1204: High Advisor's Anger (5k)

This is what it means to have food in hand and not be afraid.

"Will there be a delay in progress?" Some comrades still think that they should continue to make repairs and complete the project first.

Gao Zhendong shook his head: "The trouble this configuration will bring to long-range air-to-air missiles will delay your progress even further, and you may not even be able to complete it."

Judging from what Gao Zhendong knew in his previous life, with our original technical capabilities, we did not have usable medium-range interception capability until the Shoe Country provided A bullets. From this perspective, if there is no major change, there is actually no hope of converting the Sparrow into a long-range bullet.

Even if comrades have the experience of imitating sparrows in this life, it will not work. The congenital defects of the configuration are problems that are born with, which are difficult to cure, extremely costly and may even be incurable.

However, Gao Zhendong did not just keep a high profile. If he did things that way, he would be hated by everyone no matter how high his position was.

"Comrades, don't worry about the time issue. I will take charge of this matter. I will coordinate and resolve the opinions of the Defense Work Committee and the Air Equipment Bureau."

Gao Zhendong's words made the comrades smile, and everything was fine.

After all, work is done within a time limit, and they don't have the confidence of a senior consultant to influence the opinions of the Defense Work Committee or even the Air Equipment Bureau. Especially the latter, who always want more and more, and wish they could approve the project today, test-fire tomorrow, finalize the design the day after tomorrow, and mass-produce equipment in a week.

And what Gao Zhendong said is probably the difference between "Brothers, follow me" and "Comrades, follow me". The feelings of the comrades who are doing the actual work are very different.

"Then, Consultant Gao, do you have any recommended plans?" It's time to strike while the iron is hot.

Gao Zhendong nodded: "We will discuss the details later, but I can give you a rough idea now. You can consider whether this plan is suitable. If it is not suitable, we can discuss it again."

I can’t go into detail because I just got the book and haven’t finished reading it yet.

But the big plan can be talked about. Gao Zhendong already had a plan in his mind. Even if he didn't get the book, he would have chosen this plan because the background of this plan is very impressive.

The top two are carefully selected. Just ask yourself if they are awesome or not?
The overall configuration that we chose together with the Citigroup guys is a small central wing + a small fully movable tail wing. As for the details, we can leave it aside for later.

It is no exaggeration to say that this configuration can be used until the 21st century!

Of course, there is a prerequisite for using this configuration, and that is the need for good solid propellant. Otherwise, even a powerful American like the United States had to make the AIM-70 Phoenix thick and strong in order to hit targets over 100 kilometers away in the 54s.

What a coincidence, isn't it? We actually have this thing now.

As for the R-77 configuration, it is actually not a good choice for air-to-air missiles because the resistance is too large. This resistance comes from both the large wetted area of ​​the middle wing and the grille tail wing that does not look large but is actually quite large.

Why do military fans in the 21st century laugh at the American people for using standard missiles as ultra-long-range air-to-air missiles when there are no ultra-long-range air-to-air missiles? It is because of that structure, which is fine for ship-to-air missiles and even has a long life, but it is not suitable for air-to-air missiles, and it is more of a forced move.

"With such a small wing, won't the lift be enough?" When the comrades saw Gao Zhendong draw this configuration on the blackboard, they expressed some concern.

Gao Zhendong said: "Actually, you all should know that the main lift of a missile comes from the missile body itself. If the missile body is well designed, there will be no problem with lift."

It is not known whether the comrades knew this originally, but they know it now.

"This tail wing is so small, will the control torque it provides be insufficient?" Just ask while people are still here.

"There are many ways to solve this problem. The one with the simplest principle, the best effect, and the most difficult one is to make the missile statically unstable. In that case, a small torque can make it make a big move."

The AIM-120 is statically unstable. As for our later Thunderbolt-12 and Thunderbolt-15, Gao Zhendong didn't know about this and he didn't dare to ask at that time.

When the comrades heard this, they suddenly realized that it was no wonder that they had to start over again. This was no small change. With Gao Zhendong's explanation of static stability just now, the comrades knew how big a change this sentence would bring.

That requires closed-loop flight control, not to mention the resulting changes in the overall layout of the missile.

Although it is more difficult, the comrades are more interested and more motivated. They are determined to do their best.

This is also the confidence brought by the newly finalized Thunder-45 with a range of 2 kilometers.

Even if we take our time, the Thunder-2 is already ahead of everyone else, and not just by a little bit. So we have the time to calm down, take our time, and make a good missile.

In other words, there are two, one long-range and one ultra-long-range.

Some comrades even think that these two things should not be developed too quickly. If they are developed too quickly, Lei Dian-2 will cry to death. What does it mean? They have to be laid off just after taking up the post for a few years?

However, given our current economic situation, this possibility is not very high. Even if a better one is developed, the Thunder-2, which has far superior performance but is cheaper, is expected to have to stand for a long time.

"Chief Engineer Gao, I think there is an airfoil that can solve the problem of insufficient control torque even in the case of a statically stable structure." A comrade raised his hand.

Wouldn't it be great if the problem of missile maneuverability could be solved under a statically stable structure? In that case, missiles wouldn't be so difficult to build.

Gao Zhendong turned his head with interest: "Oh? Tell me about it."

The comrade stood up excitedly, walked to the blackboard and began to draw his idea.

As the chalk in his hand flowed across the blackboard, the smile on Gao Zhendong's face became more and more obvious.

It's not a mockery or a laugh, I'm really happy. Our comrades are still very supportive.

What this comrade drew is the grille wing, which is the grille wing used on the R-77.

"...This airfoil has a large effective total area, can provide a greater deflection moment within a limited size, and has a higher control efficiency than ordinary delta wings or trapezoidal wings..."

The principle of this tail wing is simple and clear. It is the kind that you don’t know until it is explained, but once it is explained, you will understand it clearly and you can tell it at a glance.

The comrades looked at it and nodded, saying that this method was indeed a good one and it did not require a very large tail wing.

It seems that there is hope of solving the problem under static stability, so there is no need to make it so difficult.

The comrades discussed the matter at once, and then turned their attention to Gao Zhendong.

Gao Zhendong smiled happily and said affirmatively as soon as he opened his mouth: "Very good! Very good! This wing shape can indeed greatly improve the control efficiency of the tail fin and enhance the maneuverability of the missile..."

The comrade was very happy. Although there is a saying that goes "Praise first before criticizing", no matter what, it was something to be proud of to be praised by the senior consultant.

"However, I still suggest that we go the route of static instability. As long as this problem is overcome, this configuration can be used for a very long time. Once the configuration is determined, it will be difficult to change it later, unless a new model is made. Of course, I don't recommend using this tail wing. The main reason is that in addition to the advantage of high control efficiency, this tail wing has a huge disadvantage - high resistance! This is a huge problem for long-range and ultra-long-range air-to-air missiles that focus on range. At the same time, according to aerodynamic analysis, this airfoil will not perform well in the transonic section, and the control efficiency will be reduced."

The last two sentences are the conclusions in the book. As for the other defect, the large radar cross-section, it can basically be ignored at this stage, because fighter jets are much larger than it, so there is no need to care about this little bit. Although the R-77 has been praised a lot, Gao Zhendong has never been very interested in it. The range is greatly discounted. The actual range is probably the lowest among the same generation of medium-range active air-to-air missiles with a range of 2.5 kilometers.

In addition to the fact that rocket engine technology has not kept up, another major reason is the great resistance.

Rumor has it that the Russians used this structure to give the R-77 a certain level of combat capability. After all, it is even equipped with a gas rudder.

However, Gao Zhendong felt that this type of configuration would most likely fail to control the flight of a statically unstable missile. The gas rudder was useless after the propellant burned out, and in order to obtain the large maneuvering control torque required for a statically stable missile, this type of tail had to be used.

After all, when the R-77 appeared, the Russians' electronic technology was not very good. The statically unstable flight control in such a small body of an air-to-air missile should have been a big challenge for the Russians.

However, this view is also Gao Zhendong's own analysis and cannot be taken seriously. Anyway, an obvious fact is that the R-77 really cannot fly far.

These words, of course, cannot be said here, but his words did remind his comrades that for long-range and ultra-long-range weapons, the most important thing is the range.

It is better that the senior consultant has a clearer mind and can always focus on the core issues. He is not like a bear trying to pick corn - picking and dropping it as he goes along.

The comrade who proposed the grille wing was a little frustrated. After all, it was a very useful idea, but it did go against the core goal of this missile.

At this moment, Gao Zhendong changed the subject and said, "However, regarding this airfoil, I suggest that you can dig deeper into it as a technical reserve. After all, its advantages and disadvantages are very distinct, and it can really be used in certain situations."

This thing can really be used in other places. Gao Zhendong thinks that since the comrades have brought it up, it would be a waste not to make good use of it.

This statement made the comrade who proposed the grille wing change from sadness to joy. Look, the attitude of the high-level consultant is so scientific and his consideration is so thorough.

Upon hearing this, Vice President Zhou smiled and said, "Well, Consultant Gao's suggestion is very good. We will study it when we go back." Since Gao Zhendong has taken the initiative to propose a study, the Institute of Advanced Studies, as the beneficiary, must take the initiative to express its opinion.

"Are there any problems with the project or funding?" Gao Zhendong asked with a smile.

"No problem. We are too embarrassed to ask our superiors for research of this level. We can just digest it within our institute. Maybe when it is used, we can even publicize our hard work, self-raised resources, and not causing trouble for the country. Hahaha." Vice President Zhou is also a wonderful person. He speaks very frankly and does not even hide his little tricks for publicity. Instead, he appears very frank.

"Okay then, I won't interfere for now."

With this comrade's example, other comrades became more motivated. The senior consultant can not only provide technology, but also has the ability to provide resources for the comrades' new ideas.

"Advisor Gao, if we add gas rudders to this missile, can we improve its maneuverability?" This person came over after the development of the Thunder-3 air-to-air missile was completed and is familiar with the gas rudders.

Well, you guys are going to grab all the R-77s. Gao Zhendong thought it was quite interesting. The comrades were not weak at all when they started brainstorming.

However, Gao Zhendong was still not interested in this suggestion.

"I don't recommend it. The gas rudder will increase the complexity of the tail structure and increase the cost. This thing is expensive to begin with, so it's better to save as much as possible. At the same time, the gas rudder will lose its function after the fuel is burned out. Even for dual-pulse engines, this situation is very common..."

It is normal for long-range air-to-air missiles to burn out their fuel, and at this time the gas rudder becomes a dead weight.

In terms of cost, the Air Force is definitely willing to pay more for this missile, but it cannot just spend it recklessly. Moreover, what is more important is what Gao Zhendong said next: "Moreover, as long as the statically unstable structure flight control is successful, the maneuverability brought by the small tail wing will be sufficient for the needs of medium-range interception missiles. This is not a close-range combat missile, so there is no need for such a large overload. We must be restrained in the use of technology and not be greedy."

Restraint and non-greed. Many comrades have only now realized the importance of these two words in scientific research. This principle requires standing at a very high level to be understood. Many comrades had no idea about it before.

Many comrades wrote down these two words thoughtfully in their notebooks.

Gao Zhendong continued, "Anyway, we are still doing preliminary work on long-range and ultra-long-range air-to-air missiles. Comrades can go back and study this configuration and suggestions to see if there is any progress. If it doesn't work out, we can consider other things."

If you really can't do it, the big, black and bulky AIM-54 Phoenix is ​​not a bad choice. It's just that in that situation, ordinary fighter jets can hardly carry it, or can only carry one.

This thing is not only heavy, but also thick. It is impossible to hang two of them on it. Hanging one will affect the balance, so it can only be hung on the belly of the aircraft. However, the space in the belly is limited and the available models are extremely limited. In short, Gao Zhendong would not consider this thing unless it is absolutely necessary.

"Okay, let's go back and think about it carefully. Try to move in this direction." said the chief designer of the ultra-long-range air-to-air missile model.

Having said that, he was still worried, mainly because the relevant theories were too weak, or even blank, which made them more or less worried.

Hearing this, Gao Zhendong looked at him and smiled without saying anything.

After finishing this matter, Gao Zhendong turned to the comrades in the surface-to-air/ship-to-air medium-range missiles and said, "I don't have any suggestions for you. Your changes are minimal. My suggestion is to conduct more experiments and make careful adjustments. In fact, there is no big problem..."

The chief designer of this type of missile had already vaguely anticipated this. He was well aware of the long-term coexistence of radicalism and conservatism in technology of the senior advisor, and their missile was just the kind that was suitable for being more conservative. The main reason was that the current situation was already close to being usable, so there was no need for drastic changes. If anything, it would be that adding boosters to achieve a longer range might take a lot of thought, but that would be after the improvement of the existing missile body was completed.

But Gao Zhendong did not completely disappoint him, or rather, he gave his comrades more surprises.

"As for the overall design of the missile, I have a lot of ideas just now. So, I will summarize them later and put my ideas on the overall design of tactical missiles into a manuscript. If you have time, you may want to take a look at it." Gao Zhendong said with a smile.

Hmm? This is simply a pie in the sky. Senior designers including Vice President Zhou were all overjoyed, except that the word "just now" made them feel a little uncomfortable.

Senior consultant is so angry!
The quality of Comrade Gao Zhendong's summary materials is quite guaranteed, which is unbelievable. Although he covers many industries, whenever he publishes a monograph, he always hits the pain points of that industry and solves many problems. Moreover, many of them are theoretical guidance, which makes comrades with weak theoretical foundation look forward to it.

It would be fine if it was like this in one industry, but it is like this in many industries. It is hard to believe, but we have to believe it. The facts are there and we cannot help but accept it.

Comrades who work on hair growth have a deep understanding of this. Advisor Gao’s previous monograph is still in the archives of the Defense Work Committee, and ordinary people have no chance to see it.

"That's great! Mr. Gao, we are waiting for your masterpiece." Vice President Zhou was the first to respond.

"I guess we'll have to run to the archives of the Defense Work Committee every day for this thing, hehe." A comrade joked. He said he would have to run there every day, but there was no complaint in his tone. If this thing really existed, he would be willing to run there every day.

"It's just some ideas on the overall design, not much." Gao Zhendong felt to himself that this was not modesty, but there really was not much.

It was impossible to take out the book all at once. There was really no way to explain it. Although he didn't need to explain anything now, others would not believe it when they saw the thickness of the book. It was better to be safe.

Fortunately, everyone is in the early stages of their work, and now we just need to come up with the overall design part according to their progress, which will not delay the work and can be explained away.

As for the others, I will bring them out bit by bit as I progress and help my comrades solve problems.

There's no problem later? That's impossible. Even if there is no problem, Gao Zhendong will have to create some problems, otherwise it will be inconvenient to unload the goods.

After talking about the matter for a while, Vice President Zhou smiled and said, "Advisor Gao, the meal you mentioned at the beginning about Master He..."

The comrades all laughed happily.
