Siheyuan: I eat melons while doing scientific research

Chapter 1128: Accompanying air defense system? More than that (two more chapters will be released after midnight)

The comrades from the Land Equipment Bureau were overjoyed, saying, "Well, it's finally our turn."

The reason why they are anxious is that they had a great time playing the dirty three last year, but at the same time they also realized the urgency of the aerial threat. After all, our target has never been the dirty three, but the two largest ones.

After all, if we can make these weapons, there is no reason why others cannot, especially when the enemy will spare no effort to fund our current biggest combat goal.

That is not an imaginary enemy, but a real enemy.

Coupled with the experience gained from Jiaozhi, helicopters are becoming more and more prevalent, fortunately there are portable air defense missiles.

When the irrelevant people dispersed, everyone sat down again. As soon as they sat down, the comrade from the Land Equipment Bureau spoke impatiently: "Accompany the air defense, Zhendong, tell me your ideas."

Gao Zhendong is one of us, so the people from the Luzhuang Bureau didn’t even need to use the word “comrade” to refer to him.

The leader of the Defense Work Committee also nodded, indicating that Gao Zhendong should speak first.

He estimated that the person with the most complete and thoughtful ideas in this regard should be Gao Zhendong himself. The comrades in the Research Institute could be responsible for implementation, but the planning might not be mature enough for the time being.

Gao Zhendong stood up and began to draw on the blackboard.

"My idea is that missiles are not the most important thing for air defense..."

Field accompanying air defense systems like the later JIN-17 are not urgent at the moment as their performance has been exceeded. Instead, other things are more urgent.

"Missiles are not the main thing? Then do you mean anti-aircraft guns?" said a comrade from the Land Equipment Bureau.

Gao Zhendong nodded and shook his head: "My idea is to make a combined missile and artillery, responsible for air defense within a range of 3 kilometers, and the main targets of attack are not only low-speed and low-altitude aircraft, but also ammunition!"

The comrades were shocked, "Ammunition?" they asked in unison.

It's not surprising that they were so surprised. As we all know, hitting a bullet or a shell is simply a fantasy.

Gao Zhendong nodded: "Yes, the ammunition I'm talking about is not artillery shells, but guided ammunition like laser-guided bombs! In other words, high-value ammunition. The target of the enemy's high-value ammunition must be our high-value target."

It's quite interesting. The comrades from the Defense Working Committee and the Army Equipment Bureau looked at each other and thought that in this matter, the enemy's aircraft might not be the main factor. Even if we use our own strike capability to evaluate the imaginary enemy, it would be almost impossible to stop the enemy from dropping precision-guided munitions without full control of the air superiority. Now it is better with mobile air defense missiles with a range of 30 kilometers, but the ammunition thrown out cannot be driven away.

If it is possible to defend against laser-guided bombs by affecting guided vehicles, then it would not be so easy to defend against TV-guided bombs that have no directional requirements for the carrier aircraft and long-range dispensers that win by quantity.

"But how did the ammunition hit the target?" Some comrades found this a little unbelievable.

Gao Zhendong smiled and said, "In fact, if you take away the outer layer of an air-dropped bomb, it is essentially just a small target with a limited flying speed. Its flying speed is not even as fast as that of an airplane."

The comrades felt that there seemed to be some trick. Yes, bombs have no power, and they may not fly as fast as airplanes, but the targets are really small.

Attack low, slow and small. Not to mention now, even when Gao Zhendong traveled through time, few countries in the world had truly solved this problem.

"Well, I have an idea. The plane may not be able to hit it, but the ammunition can be destroyed!" The leader of the Defense Committee laughed. It's true that Comrade Zhendong has a smart brain.

"And it can also take into account helicopters and low-altitude and low-speed aircraft... What a good idea. In this way, if an enemy plane slips through the air defense network, we will not be completely defenseless. As long as we can shoot down its ammunition, it will be enough." The comrades in the army felt that this thing was indeed a good idea.

"Then what is the concept of the integrated missile and artillery system you mentioned?" The comrades then remembered that Gao Zhendong had proposed a new concept.

At this time, Gao Zhendong had almost finished drawing the schematic diagram on the blackboard. He patted the chalk dust on his hands and pointed at the schematic diagram and said, "This is it. You can see it at a glance. Combine radar, missiles, and artillery into the same firepower unit. Missiles can hit far targets and aircraft, and artillery can hit near targets and ammunition. It forms an air defense system that can cover a range of about 10 kilometers."

Although 10 kilometers may not sound like a lot, it is actually a very exaggerated number for field air defense at that time. For example, the JINGQI-61, which is now confirmed to be gone, has a range of only 10 kilometers. Of course, this has a lot to do with our backward technology.

When necessary, I can play it flat, Gao Zhendong thought.

On the blackboard was a tracked combat vehicle with a turret in the middle and a short-looking gun on the turret. However, no one could figure out why such a large caliber was used with such a small multiple of caliber.

On both sides of the turret are several missile launch tubes.

Not to mention the army, other comrades all liked this thing at first sight, even if it was just a concept map, but it looked very martial.

Pipes, big pipes, and more pipes… Gao Zhendong’s mind was filled with the magical naan text sung by his comrades from Xinjiang.

"Well, Comrade Zhendong's idea is good..."

"But we don't have such a small missile with such a long range." Gao Zhendong said with a smile: "Our whole special missile is small in size and has a large booster! This kind of missile is not used to attack large aircraft anyway, so it doesn't matter if it is a little smaller."

After saying that, he drew another schematic diagram on the blackboard and roughly marked the dimensions.

The Russians' 2K22 Tunguska uses a missile with this architecture, and the earliest model has a range of 8 kilometers.

The comrades from the Institute of Guidance and Research estimated: "Well, this structure, this size, can indeed hit farther, but 10 kilometers is still a bit of a stretch."

"You don't have to worry about this. We now have a new type of propellant. It's not too expensive, but its specific impulse is good, better than what you are using now." The chief engineer of the Defense Work Committee said with a smile.

The Defense Work Committee has obtained HTPB propellant from Gao Zhendong, especially the manufacturing and synthesis of HTPB.

Looking at Gao Zhendong who just smiled and said nothing, the comrades in the Institute of Research understood that it was probably the work of this man again. After all, many new energetic materials came out of his hands and they had used them all.

"That's fine, but this gun looks so strange to me. The caliber is too large, so the rate of fire can't be increased. Also, the barrel is short, so the ballistic performance of the shells may not be good."

Well, I was lazy and caused my comrades to misunderstand me.

"This gun is not a single-barreled gun. In fact, it is a set of 25mm barrels." Gao Zhendong added a few small circles on the short and thick muzzle.

"Gatling gun?" This thing was invented a long time ago. Even those who are not familiar with guns and artillery know that it is a man's romance.

"Yes, and it's an electrically powered Gatling gun!" Gao Zhendong said with a smile.

"Isn't it a bit of a waste of materials?" Some comrades hesitated.

Gao Zhendong shook his head: "If you want a high rate of fire, Gatling is the best solution. If you want to intercept ammunition, barrage is better than shrapnel."

Comrades in the Army don’t care, they just want enough pipes.

"But if we want a high rate of fire, a revolver or a gast cannon would also work, right?"

Gao Zhendong shook his head again: "The Gaster Gun's firing rate is still not high enough. As for the revolving gun, it only has one barrel and cannot dissipate heat, so its continuous firing capability is not good."

"Then why not use the internal energy source of gunpowder gas?"

"Internal energy is naturally susceptible to disturbances, so it's hard to hit accurately." Gao Zhendong said with a smile.

At this time, the comrades in the army remembered that Comrade Gao Zhendong was also a gun expert!
"We have such good motors, speed control, and transmission devices?"

Gao Zhendong smiled even more happily.

"The GTO is almost done. It's perfect for use here. Gears are used for transmission. There are no special requirements for this thing. It can handle it. As for the motor, if it doesn't work, a slightly larger one will do. It's carried on the turret anyway."

No one is quite clear about what GTO is, but what everyone knows very well is that if Gao Zhendong says it can be used, then it really can be used.

"That seems pretty good... But what about the eyes? We have radars that can detect and track such a small target?"

Gao Zhendong nodded and looked towards the Land Construction Bureau.

"Our anti-artillery radar has been specially optimized for the detection and tracking of such small targets. We can learn from them and then use high-frequency radar combined with advanced technologies such as pulse Doppler to detect bombs without any problems."

Comrade Gao Zhendong is so familiar with the equipment that he can easily get these things and most of them are already prepared.

"If that's the case, we need new missiles and new cannons," the Defense Work Committee murmured.

"There is no big problem with this missile. Although the missile is new, the technology is mature." Comrades from the Institute of Navigation and Research are very confident that the technology of the JF-2, which has just been finalized, can be transferred down. Moreover, one of the major advantages of the JF-2 technology is that it is cheap.

Gao Zhendong knew it very well. After all, he knew it very well in his previous life. The Jingqi-12 and Jingqi-22 line was famous for being cheap, and the Jingqi-2 in this life happened to use similar guidance technology. In the large family of semi-active guidance missiles, it was considered the cheapest one, but the effect was not bad.

"The cannon is actually not a big problem. One big advantage of the external energy Gatling gun is its simple structure. Since it does not require internal energy to drive it, many things don't need to be considered at all. It is faster to build than the internal energy one." Gao Zhendong said.

Then he added another drastic measure: "Moreover, if this gun is completed, it can be separated and equipped with radar and optical systems, and placed on high-value ships to defend against enemy missiles! Or this entire turret can be moved to a small boat and used as the main gun or close-range air defense."

The comrades in the navy are still there. When they heard this, they were very excited. I want this, I want this!
"Defense against enemy anti-ship missiles?"
