Chapter seven hundred and sixty fifth gun mantlet and trunnion
Since entering the workshop, Mr. Zhu's eyes have been staring at the sky cart. The sky cart above his head is being lifted, with turrets one by one.
The tank's turret is a heavy iron lump. The small domestic 59 series tank has a very small turret, and it is more than ten tons. The turret of the M1 tank is a giant, and the weight of this turret is also very large.
of.
29 tons! This is the public data. Thinking about this number, it is extremely surprising. This order of magnitude is almost the same as the 59 tank. (Baidu, I don’t know if this data is reliable)
The turret of a tank was almost overwhelmed by the weight of a tank on its own.
why is that?
Because Westerners are tall, they must have enough space. From the side, the turret's tailstock is almost flush with half of the engine compartment behind the tank body. Such a tailstock can
It is used to balance the weight of the turret and can also be equipped with shells. This is the design idea of the West.
Three huge iron chains, hanging a turret, are slowly passing overhead, towards a tank that has been installed on the chassis. When the turret is buckled on the body of the vehicle, a tank is roughly
Assembled.
Zhu Lao was looking at this turret carefully. Now, the design of the new third-generation tank is about to be unfolded. The body has generally been outlined, but there is still no specific plan in terms of the turret, and it is still learning from everyone's strengths.
The turret of the M1 tank is also worth considering research.
Unlike the vertical side of the Leopard 2 tank, the sides of the M1 tank turret are inclined. Although the internal space is reduced, the protection ability of the turret can be greatly improved by tilting the armor.
This design is quite suitable, so our third-generation tank can also be used according to this plan. However, this turret is too big, and on our tank, this turret should be reduced as much as possible.
At this time, the turret was still lifting forward. The turret basket below was made of alloy steel, reflecting white light, and looked very beautiful. Then, slowly descending and turning, finally, I saw the front of the turret.
Cannon shield!
In the design of tank turrets, gun shields are a key and a top priority for designers.
The tank's gun barrel must be able to move, and the left and right movements are achieved through the rotation of the turret, while the up and down rotation can only be achieved by setting a rotation axis in front of the turret, which is the trunnion.
The gun barrel rotates up and down with the trunnion. At the same time, the turret has to leave a space in front for the gun barrel to move up and down. How to solve the bulletproof problem in this part of the space? Then the gun shield needs to be used.
As the name suggests, the cannon shield is a shield used to block the gaps in the cannon installation holes that existed when the tank first appeared. It is installed in the center of the turret. The design of the cannon shield also has a lot of knowledge.
.
First of all, this gun shield can be installed outside or inside, which forms the term "internal and external gun shield".
If you look at the tanks in the east, take the common 59 tanks as an example. What is the root of the gun barrel? Canvas! What is inside the canvas? No one knows because it has not been taken apart.
In fact, this one is a built-in gun shield like a plug. (Some say it is called an external gun shield, after all, it is not in the turret)
The position of the gun shield is very important because the probability of being hit here is too high. Therefore, the turrets designed in the West use a large gun shield that is enlarged and thickened. The trunnions are fixed in the turret armor and external guns are used.
The shield blocks the cannon installation hole and blocks part of the front of the turret, using a heavy cannon shield as the armor that mainly absorbs damage.
From the appearance, here is a piece of armored steel with a large angle curve, moving along with the pitch of the gun barrel!
Western gun shields should be used as the main force of protection, but Soviet tanks are not. Soviet tanks are just like plugs to plug the gap left after the gun is installed to prevent shells and shrapnel from shooting into this gap.
Inside the car, that's all.
The main protection is achieved by tank turrets, which can reduce the projection area of this cannon shield as much as possible.
As for the canvas outside, they are mainly imitated and fallen into dust.
Although the plug is small, it is thick! At the same time, the outer edge angle is very large. If you hit it, the chance of jumping is quite high and the protection is good.
However, because this design fixes the gun trunnions behind the main armor, it will seriously affect the pitch of the gun barrel, and the low turret design, resulting in the strange "Oriental tank never bows its head" and the tilt angle is small
It's incredible.
Technology is constantly improving and has developed to the third generation of tanks. The design of this cannon shield and trunnion has naturally gone further. Looking at the cannon shield of the turret, you can find that it has changed its thinking.
It abandoned the protection idea of using a cannon shield to absorb damage and only acted as a plug. However, in order to avoid limiting the pitch of the cannon, the plug should be more external and at the same time be larger in area. This is a design of a cannon shield.
Now, from here, you can also see a huge bullet zone, which is definitely a terrible result if it is hit by a shell.
Try to absorb the advantages of the other party's design. For those disadvantages, you must try every means to avoid them. Mr. Zhu's mind has already turned quickly, considering the design scheme that his side can adopt, and considering how to combine the East and the West.
, learn from others' strengths and design your own advanced tanks.
Qin Zhenhua followed Mr. Zhu's gaze and also knew what Mr. Zhu thought, so he continued to ask questions to the other party.
"Your turret is beautifully designed."
The other party will definitely not disclose the true meaning, but you can use the line to figure out the other party’s design ideas. How much you can gain this time depends on everyone’s ability to comprehend.
"Yes." Speaking of this turret, Dr. Wright is also quite proud: "In our design philosophy, it is a key to protect the life of the tank hands, so we must separate the ammunition room from the crew.
To do this, we have added space for the turret, and most of the ammunition is stored at the tail."
This is actually a popular design concept in the West. In order to protect the safety of the tank handle, the ammunition and the crew members must be separated. However, the tanks are for war, and the tank handles must take shells!
