Chapter 515: Imitation of K-5?

Naturally, the nephews scoffed at the newspaper's statement, calling it "the halo of admirers", "forced correctness", "thirty years ahead of the times", and "ignoring the facts".

However, many people think that this statement makes sense.

As for someone who once interviewed Mr. Gao about this matter, Mr. Gao just smiled with a childlike mischievous look on his face: "Guess?"
-
The Third Steel Rolling Mill acted very quickly regarding the adjustments to Gao Zhendong's work with the Security Department. As soon as Director Zhang finished communicating with Gao Zhendong, the notice was posted on the bulletin board.

"Due to work needs...,...from the date of this announcement, Comrade Gao Zhendong will no longer be responsible for the training-related work of the Security Department. His position as deputy chief of the Security Department's Training Section will be concurrently assumed by Comrade Xie Jianye of the Internal Security Section, Internal Security Section 5 of the Security Department..."

Comrades who passed by and saw this discussed it briefly, but no one took it seriously.

"Oh, the factory has finally decided to reassign Chief Engineer Gao's job in the training department. Chief Engineer Gao's burden is finally less heavy."

"We are all human. If it weren't for Chief Engineer Gao's comrade coming here, I don't think the Security Department would have been willing to let Chief Engineer Gao go."

"It should have been done a long time ago. With Chief Engineer Gao holding that position, I think the training section chief must be miserable all day long, haha."

"This Xie Jianye is incredible. He has risen to the position of deputy section chief so quickly."

"..."

In short, everyone has a similar opinion. This is normal and should happen. There is no other emotion. It is just an ordinary personnel adjustment.

There were only two people who were truly happy about it.

One person is naturally Xie Jianye himself. This notice means that he has officially entered the ranks of what can truly be called "cadres". Of course, he is still a long way from being a "leading cadre", but after all, he has started.

For this purpose, he even prepared a meal at home. Chen Yuehong happily prepared a large table and invited Gao Zhendong and Wang Dezhuo's families to celebrate together.

And the other one was happy, oh, yes, he got hit in the bangs.

"Look, what did I say? The factory has reduced Gao Zhendong's power again. Boil the frog in warm water, and take it slow. There are experts in the factory."

This old guy always uses his brain in the wrong places. What does this have to do with the masters?

Gao Zhendong was not aware of all this. After the Third Rolling Mill adjusted his security-related work, until the Chinese New Year, in addition to his own work, he only attended one meeting of the Security Working Committee.

Things were going smoothly in the 17th and 12th Ministries of Machine Building. On the contrary, he was rarely called to attend meetings, and there were not many meetings to hold.

The situation is different on the Defense Work Committee's side. Whenever there is something to do, they prefer to involve Gao Zhendong, because he is involved in everything. Materials, energetic materials, automatic control, electronic technology, it seems that he has a share in all of them and he seems to be involved in everything. The key is that the results of his involvement are generally pretty good.

Gao Zhendong had not expected this meeting, which was to discuss the work plan for imitating the Russian K-5 radar air-to-air missile, which was Gao Zhendong's Thunder-1 in his previous life. In this life, it was squeezed into Thunder-2 due to the early success of the infrared air-to-air missile.

Moreover, the imitation work seems to have been advanced, which may be somewhat related to Gao Zhendong's butterfly.

The K-5 was introduced together with the predecessor of the Type 6, the MiG-19, at a relatively early time, in 58. The actual decision to start imitation was originally made in July 1961.

To be honest, Gao Zhendong was not very interested in the K-5 missile. He knew a little about it, but not much. This was mainly because in his previous life, the missile was too old and its performance was too poor. It could only be said that it occupied a niche, but it had no presence at all.

We can't really say that our imitation of this thing is bad. Our comrades still managed to basically imitate it successfully according to the performance of the original even when the Russians tore up the agreement, withdrew their experts and stopped the supply of materials.

The problem with this bullet is that the original version was garbage, and even the Russians themselves retired it very quickly.

We were the same. We discontinued production very quickly, in 74, only ten years after it was finalized. This was very rare in that era. In those days when high-tech weapons were scarce, any weapon that could be of some use would not be completely useless. Yet production was discontinued in 74.

This thing is so unpopular that in Gao Zhendong's previous life, if he was not a slightly more experienced military fan, he would not have known about the existence of the Thunder-1 missile. He thought that our air-to-air missiles started with the Thunder-5, just as fighter jets started with the Z-2.

The research institute is also responsible for the preliminary work of replicating this thing, but it is a different team.

Gao Zhendong is very familiar with the person in charge of infrared missiles in the Missile Research Institute, as he is the deputy chief designer of the modified Thunderbolt-1. As for other comrades, except for the dean and chief engineer who he has had some dealings with, Gao Zhendong is not so familiar with them. The Missile Research Institute is not a small unit.

But it was obvious that the comrades in the Institute of Guidance and Research were quite familiar with him. Even if they had not met him, they had at least heard of his name. Before the meeting started, they came over to say hello to him, the technical consultant of the Institute of Guidance and Research, and wished him a Happy New Year.

As Gao Zhendong played an important role in the Lei Dian-1, served as the deputy chief designer of the modification, and was taking the course "Automatic Control Principles" at Beijing University of Technology, everyone thought that his opinions on air-to-air missiles were very important. The meeting started soon. Gao Zhendong sat next to the leader of the Defense Working Committee and listened to the report of the comrades of the Guidance Research Institute. Including the chief engineer of the Defense Working Committee on the other side, everyone had the same expression - not good.

This is not a good look. It is not directed at the work of the comrades in the Missile Research Institute, but directly at the K-5 missile itself.

The comrades from the Air Force also frowned. This thing, wow.

If the comrades in the Defense Work Committee and the Air Force did not realize how bad the Russian garbage was without any comparison, then after the success of the Thunder-1, this problem completely surfaced, even though the two have different guidance principles and are theoretically used in two different occasions.

After listening to the report from the comrades from the Institute of Guidance and Research, Gao Zhendong decided not to waste everyone's time and let himself be the bad guy.

According to his observations on the scene, even the comrades in the Institute of Research and Development were a little disgusted with this thing, and felt like they were giving a report with their noses pinched.

Gao Zhendong had heard about this kind of report from his mentor in his previous life. Even though he knew it was a mess, he still had to bite the bullet and do it. After finishing it, he felt terrible.

As soon as the report was finished, Gao Zhendong, contrary to his usual behavior of listening to his comrades speak first, asked to speak first this time.

This surprised the other comrades. This was rare. Comrade Gao Zhendong was used to listening to other comrades' opinions first. This time he spoke so early and so proactively. It seemed that this thing was very difficult for him to tolerate.

The first thing Gao Zhendong said when he came up was: "I think we should not continue with this project for now. We should think carefully about whether we should do the subsequent work."

Here it comes, the familiar "Gao Dapao" is here again.

"Tell me your reasons." The leader of the Defense Work Committee asked us to explain our reasons, but his tone and expression gave off the feeling of "kill this thing quickly so that our comrades can be freed up to do something else."

Gao Zhendong did not hesitate: "This bomb has no use. From the perspective of maneuverability, it can only chase after large bombers. But from the perspective of its range, it is completely unable to support it."

The K-5 uses a very rare guidance method - radar beam guidance.

This method is completely extinct in later radar air-to-air missiles, the reason is simple, it is difficult to use. By the way, the AIM-7 Sparrow of the United States is also like this, and the result is similar to the K-5. The United States even reacts faster and withdraws the equipment faster than the Russians.

Radar beam guidance looks similar in principle to laser beam guidance. The carrier aircraft emits a beam of radar waves pointing at the target. The missile detects this radar wave through the radar receiver at the tail of the missile, obtains the deviation, and outputs a control signal to control the missile to fly towards the target.

It looks like the missile is flying along on the radar waves, so it is called beam guidance.

It looks good, but there is a problem. The directionality of radar waves cannot be compared with that of lasers, which leads to the tragedy of this missile.

Its guidance method and its own maneuverability determine that it cannot hit highly maneuverable targets and can only hit targets such as bombers.

Comrades from the Institute of Guidance and Research still have to try to save the situation. After all, this is their job.

"Boss Gao, after receiving the propellant you provided, the maximum range of this missile has been increased from the original 4.5 kilometers to 6 kilometers."

The structure of the K-5 missile is extremely rare. It is not an exaggeration to say that it is one of the few wonders among air-to-air missiles.

Since this thing uses a radar beam guidance method, a radar signal receiving device must be arranged at the tail of the missile body. The Russians' habit of "as long as it works" has played a counter-effect here. Its rocket engine is the same as that of the Chijian-73 anti-tank missile - in the middle and rear part of the missile body, with a lateral nozzle.

This causes part of the thrust to be applied laterally. Although the symmetrically arranged nozzles can offset the lateral thrust and ensure that the missile does not yaw, this part of the thrust is actually wasted.

At this point, K-5 is not as good as Sparrow A.

After Lei Dian-1 obtained the new propellant, it was natural to consider applying it to Lei Dian-2. However, the structure of Lei Dian-2 not only has a side nozzle, but is also shorter and thicker, so the range is not increased much, at least not as long as that of Lei Dian-1.

However, this is not the fatal flaw of K-5/Thunder-2 in terms of range. The real fatal flaw is the range reduction caused by the guidance method.

Gao Zhendong smiled and said, "But the guided missile range is still the same, about 3 kilometers, right?"

The comrade from the Guidance Research Institute nodded sheepishly: "Yes, radar can only guide so far."
