The doors of this Soviet armored vehicle are indeed a little smaller, but the people in the car may not have to get off the door. They have left two holes on the top, and the soldiers inside can poke their heads out from it at any time.
, and even half of the body can be poked out.
What are the benefits of this? Is it probably for shooting while walking? Or is it for the purpose of opening the roof when you can't open the door after turning over?
Yang Zicheng sighed at this design.
For a long time, the ones designed and manufactured in China are actually armored conveyor vehicles, not infantry combat vehicles.
As the name suggests, an armored conveyor is to transport soldiers to the battlefield. With armor protection, it is better than just riding a truck. It is just a transporter and cannot be used in combat. This is an armored conveyor.
Infantry fighting vehicles not only need to be able to sit in the car and go to the battlefield, but also can fight directly in the car and shoot at the outside world.
Therefore, next to each seat, there is a special shooting hole left. In addition to this, there is a special hatch door that opens upwards, so that you can stick your head out to fight.
Yang Zicheng praised this design until Qin Zhenhua, who was beside him, said: "This cabin door design is unique, but you have to be careful of hitting people with a turret."
A turret hits people?
When everyone heard this, they suddenly realized it.
The openings on the top of the hatch are close to the turret. When the turret is in the front half of the ball, there is no problem. However, if this turret turns around, the barrel will probably be like a big stick.
He was stunned by the two people behind.
There is obviously something wrong with this design.
However, the Soviet designers had no other choice. They could not be arranged backwards because the engine was behind! Due to the engine design problem, the structure of this infantry fighting vehicle was quite strange.
Of course, the Soviet soldiers didn't think there was anything wrong with this design. After all, on the battlefield, they liked to sit directly outside the car. Few people would get into the car. This thing has thin skin and big stuffing.
If an RPG comes over, they can be reimbursed, and it is safer to be outside.
These two hatch covers have been very inspiring to the designers of infantry fighting vehicles of the Eastern Powers. Although the gun barrel will hit the people behind, there is still a great benefit to one more passage.
.
"I think our infantry fighting vehicles can also be designed in this way. The space behind us is spacious, and every soldier can have a hatch above his head. However, the flip form of this hatch is really particular."
The details are revealed. An infantry fighting vehicle, or a tank, or a small hatch on the top, is very particular.
First of all, the hatch cover has two ways of rotary opening and flip opening. Generally speaking, there are many ways to use flip opening, and this flip opening has two terms: inward opening and outward opening.
No one designed it to open inward. First of all, there are a lot of internal equipment and the space is so small. If the hatch cover is opened inward, it is impossible. At the same time, this is also in line with people's habits.
Accustomed to "pushing", and when entering, it is used to "pulling". In addition to these, it can also have other benefits. For example, if a bomb explodes outside and the shock wave is pressed down, the hatch will be covered tighter once the inside is
If you have pressure, you will be exploding and you can turn it up directly to relieve pressure. Of course, in this case, you will probably be useless.
It must have been opened outwards. At this time, there is another question: where is the axis arranged? That is to say, does the hatch cover turn forward, backward, or sideways?
Generally speaking, there are many benefits to turning forward. After turning it open, it can be used as a shield. When a person comes out of it, it can block the oncoming bullets.
At the same time, there is another advantage. When the oncoming bullet flies over, it hits the hatch cover. The impact force may push the hatch cover and close it backwards. At this time, if someone behind it, the hatch cover may be hit by the hatch cover.
However, this is better than back-turning. If back-turning, the bullet will kill the person and will also be pressed against the back-turning hatch.
However, there are also disadvantages of forward flipping. If a person wants to come out from the inside to check the situation, he has to stand up and stand high enough. If he flipping back, he can just stick his head out. At the same time, if he is in the hatchback, he can just sit up.
If there is a machine gun outside, it will block the machine gun by turning forward, and it can only be turned backward. This is the most obvious in the tank.
At the same time, if you turn forward, the person should be in the right position, otherwise it will be uncomfortable to push the hatch cover.
Now, in this infantry fighting vehicle, the hatch covers are turned on. The two positions in the front are turned forward and the other side and backward, and the two hatch covers at the back are opened on the side.
At the same time, in terms of shape, the two in the front are round and the two in the back are square, which is also different.
It can be said that seeing the real thing will cause a lot of associations, and there are knowledge everywhere. If you don’t study it carefully, you really don’t know how to design your own infantry fighting vehicle and completely adopt the other party’s plan?
The Russians’ plan may not be the best. Only by truly understanding it can we make a choice and design the best plan.
"Yes, there are some considerations, but it is best for us soldiers to decide on how to use it." At this moment, Liu Dajun spoke again.
His purpose is also very obvious. They need to operate these tanks. After operating for a long time and being proficient, they will understand the advantages and disadvantages of various advantages and disadvantages. They also have a say in how to open a hatch door.
Just like when an aircraft designer designs an aircraft, he has to ask the opinions of the test pilot, the designer of an armored vehicle must also ask the opinions of the users, that is, the soldiers, when designing.
"Yes, now the customer is God." Qin Zhenhua, who was standing by, teased: "If we had designed anything in the past, you would have to use whatever we wanted. There was no say in this. Now, the times are different."
The experience learned from Western market economy is that customers are God. This is a truth, and Liu Dajun really can say that in order to be able to operate these infantry fighting vehicles, he spared no effort.
"Yes, we have the right to speak now." Liu Dajun said: "With this infantry fighting vehicle, we can take the essence and remove the dross, so that our equipment can be more advanced.
Some designs are good, some are bad, some are suitable for us, and some are not suitable for us. Blindly imitating it directly is absolutely impossible.”
Yang Zicheng nodded repeatedly: "That's right, we absolutely cannot agree with the rear design of the engine."
