Chapter 645: Chief Engineer Gao’s rebellious period?
In the past, Gao Zhendong had to wait for his name to be called before speaking. I guess he just couldn't wait any longer today? I don’t know if it’s a good thing or a bad thing.
But no matter what, when Gao Zhendong opens his mouth to speak, he will basically stop and wait for him to speak.
As for those who don't know how to stop, it's not his turn to stop them.
"Comrade Zhendong, do you have any suggestions? Just say it, don't worry."
Although Gao Zhendong had not made much achievements in supporting artillery except tank guns in the past, who knows if he didn't have time? He seems to have never set foot in it, but there are so many areas where he can become famous.
This person cannot use common sense to judge. No, this person is unreasonable.
Fortunately, although they are unreasonable, they are still scientific and not mystical. The things they propose may be inappropriate in terms of timing, but they are basically not unreliable in terms of technology.
The comrades in the army, the National Defense Work Committee, and the artillerymen all looked at him intently.
Gao Zhendong cleared his throat: "Leave aside the cannon used for anti-artillery operations. That thing is heavy and long. Whether it is 130 plus or 122 plus, it is impossible to get on the vehicle for the time being. My suggestion is to focus on it in the near future. It’s a 122 self-propelled howitzer.”
122 pomegranates?
Comrades from the Land Loading Bureau were a little puzzled: "Chief Engineer Gao, the range of the 122mm is not very good."
We have been thinking about upgrading the 122 melon, but in Gao Zhendong’s previous life, the upgrade was not successful until the 1980s. Before that, we had been using a replica of the Lao Maozi M-1938, which has a long range, haha.
——Maximum 11.8 kilometers.
As a medium-caliber gun, this S2 technical level thing is basically pressed to the ground and rubbed.
Therefore, Gao Zhendong's suggestion puzzles everyone. If nothing else, you are not satisfied with the first one.
Gao Zhendong shook his head: "I know that the range of the Su-38 imitation is only a little over 10 kilometers, but let's not discuss the range issue first and see if the 122mm is suitable."
Su-38, short for Lao Maozi M-1938.
Although the caliber of 122mm is close to 130mm, it is actually used as a medium-caliber gun in the equipment sequence of Lao Maozi and us. Its status is similar to that of Citigroup's 105mm. What determines the range of the gun is mainly the internal ballistic design.
When Gao Zhendong said these words, the eyes of comrades who knew him better lit up, eh, what do you mean...
Let it go, let it go, especially the comrades in the Land Loading Bureau and the Army. They feel a little bit inferior in their hearts, but the comrades in artillery are still a little confused.
After not considering the 122mm range, the remaining problems are easy to think about.
In terms of power, although the 122 grenade is worse than the 152 grenade, there is no qualitative difference, especially in terms of anti-artillery, and it is not a hard target.
But 122 solves one of the most important problems: weight.
The weight of the 152 melon is over 5 tons. It is really not easy to find a chassis to carry it. For comrades who are engaged in artillery, they are not familiar with vehicle chassis. There are few mature chassis in our hands. We want to find one. It is really difficult to carry it on a chassis.
But the 122 pomegranates are about 2 and a half tons, which is different. There are more things to choose from.
"If you don't consider the range, the 122mm is really good."
"But the most important thing is the range, how can we not consider it?"
"If it's more than 2 tons, 4DL's body can barely carry it."
"It's too much, just try to force it."
"Don't worry about whether you force yourself or not, at least you can bear it."
"..."
In fact, using 4DL to transport and carry imitation Su-38 was originally our first-generation self-propelled artillery plan that Gao Zhendong knew in his previous life.
It's a convertible with a fixed shooting angle, but it's as simple as it gets. It's on the same technical level as the S2. It wasn't until the 1980s that we solved the problem and could really use it.
What Gao Zhendong wants is not this.
He also considered truck cannons, but the traffic conditions and combat environment at this time made using truck cannons really inappropriate. The off-road performance of domestic trucks was not that good. If he wanted to accompany the mechanized troops in combat, he had no choice but to give up. At least it cannot be used as main battle equipment.
At this time, there was a clear distinction between mechanized troops and motorized troops, and it was not without reason. To put it simply, tracked vehicles are mechanized, and running on tires is motorized.
Seeing that his comrades were all thinking about 4DL, Gao Zhendong quickly pulled them back. Who said they were going to 4DL? There is also a very magical chassis, but at this time, everyone never thought that this thing could be used, and it was quite good. Easy to use.
Originally, we came up with the idea of this thing in the 1980s when we were forced to have no other choice. Later we found that it worked really well.
In this regard, Gao Zhendong has no skills and is so poor that he only has the knowledge from his previous life. "Comrades, my idea is not to use 4DL. I am very familiar with this thing. Even if it is carrying 122 grenades, it is still very nervous and will seriously limit the technical and tactical performance of the self-propelled artillery." Gao Zhendong said with a smile.
The artillery comrades don't know where Gao Zhendong's words are based, but the comrades in the Land Loading Bureau know that Gao Zhendong made great efforts to improve 4DL before it was finalized, so he said that he is familiar with 4DL, which is absolutely not true. problematic.
The comrades of the Land Loading Bureau immediately threw away the idea of 4DL carrying 122 pomegranates.
"Chief Engineer Gao, what site are we using? 5DL tanks?" They thought that since Gao Zhendong was working on second-generation tanks, it was a matter of course to lower the first-generation 5DL tanks and use them as self-propelled artillery chassis.
Gao Zhendong shook his head: "No, the 5DL is based on a serious tank. The entire structure, protection, and load-bearing are all based on a tank. It is not suitable as a self-propelled artillery chassis."
The tank's armor doesn't just have to be thinned. Part of the armor also serves as a load-bearing structure. If it needs to be modified, the workload will be huge.
Seeing that everyone was a little puzzled, Gao Zhendong said: "Aren't we imitating Lao Maozi's PT-76 amphibious tank? We modified it using that chassis. I think it is very useful."
Amphibious tank? Gao Zhendong's imagination is so imaginative that everyone is confused.
Chief Engineer Gao made all his subversive opinions today. It seems that he is in his rebellious phase?
"Comrade Zhendong, land and amphibious tanks have nothing to do with this. Aren't there more things that need to be changed?" the chief engineer of the National Defense Work Committee raised an objection.
Gao Zhendong smiled and said: "Amphibious tanks are actually structurally stronger than infantry fighting vehicles. The weakness of weak protection is actually an advantage here. As a self-propelled artillery chassis that does not attach great importance to protection, this thing has a natural Advantages, easy to change.”
After speaking, he enumerated the advantages of the amphibious tank chassis.
"An amphibious tank is naturally large in body, has ample space, and has just enough protection. Moreover, its engine power is 1.5 times that of the 4DL, so it has sufficient power redundancy. With some modifications, as a universal chassis, it can even be used in more than just self-propelled artillery. ”
Universal chassis? That’s a good idea! The comrades in the Land Loading Bureau suddenly felt that their ideas had been opened up. Now they are thinking about setting up a mechanized force. It is not only self-propelled artillery that needs to be loaded onto the vehicle.
"Hey, that's a good idea!"
"Interesting, if you think about it carefully, an amphibious tank is really suitable for such modification."
"Where is this comrade from? He is very familiar with various vehicles."
"Don't ask around, pay attention to discipline. Talk about technology, talk about technology."
"Well, I think it can be changed..."
"..."
Seeing that everyone was attracted by Gao Zhendong's suggestion, the chief engineer of the National Defense Work Committee smiled and said: "Comrade Zhendong, what do you think should be changed?"
Don't bother me with anything. I'll perfect your suggestion first.
"Simple, remove the amphibious requirement, maintain at most the most basic buoyancy capability, appropriately reduce the overly large body, and then move the engine to the front to leave operating space for the rear. The body's bulletproof capabilities do not require too high a level and can prevent 12.7mm armor-piercing bullets are enough.”
This kind of general-purpose chassis is not used to face the opponent's tanks, and even the firepower threat faced by the tank is greater than it. This protection is almost enough, and the weight can be saved for other purposes.
Although the front-mounted engine of a high-target tank is extremely unpopular, as a self-propelled artillery chassis, the front-mounted engine is very popular, and the back is left for personnel to get on and off, replenish ammunition, etc.
As for amphibious conversion to floating ferry, it is necessary. Amphibious tanks have sacrificed too much in other aspects for amphibious purposes. The requirements for water speed, reserve buoyancy and other indicators are different between the two.
Gao Zhendong's suggestion plunged everyone into a heated discussion. The arguments became clearer and more energetic.
The Land Installation Bureau and the troops were delighted. In any case, even if the problem of the self-propelled artillery was not solved, the problem of the universal mechanized chassis was inadvertently solved.
The National Defense Work Committee and the Land Loading Bureau simply decided on the spot that no matter what gun or chassis was used, this thing would not be changed!
After settling this matter, the comrades of the Land Loading Bureau were still not satisfied: "General Engineer Gao, what do you think of the turret of this gun?"
Gao Zhendong shook his head: "I'm not engaged in this. I'm not familiar with it and can't explain clearly. But I just have a suggestion. You don't need as much bullet protection as 12.7mm. The turret can only protect against 7.62mm, unless there is enough weight to spare."
< br>
Only guard against 7.62? This is not like Gao Zhendong's style.
In order to upgrade the 4DL defense from 7.62 to 12.7, he almost jumped up and pointed at the researcher's nose and cursed him. Why did he change his temper today?
The artillery comrade was a little embarrassed: "Isn't the 7.62 a bit thin?"
The comrades in the army were thoughtful: "Chief Engineer Gao's suggestion is very good. If there is no spare weight for armor, 7.62 is enough. This thing is far behind and does not face the battlefield directly. It only needs basic protection." ”
Gao Zhendong added: "The important thing about this equipment is that it is sealed to facilitate the layout of the three defenses. For protection, it is almost enough. It depends on the final design result. It is good if it can be stacked. If it is not, it is not a big problem. ”
Those who knew him were relieved. He had not changed and was still thinking about the soldiers. For self-propelled artillery, three defenses are indeed more important than direct protection.
