Ordinary tank guns have low elevation angles, and of course, lower elevation angles are determined by many factors.
First of all, from the perspective of the mission of the tank, it is a direct-firing weapon. Therefore, as long as there is a certain angle, it is enough to satisfy the parabola of the shell. There is no need to consider too many issues at all, so there is no need to put it into
The elevation and descent angles of the shells are made larger.
Secondly, it is due to technical limitations.
Tank guns are not only part of what can be seen outside, but also the tank guns also have things left inside the turret. This part can be simply called the tail of the gun, and then there is a shaft in the middle, hanging on the turret, so the barrel of the gun
You can perform pitch operations. If you have more imagery, it is like a seesaw, but it is not as long as it is long on the outside and short on the inside.
When the barrel is raised, the tail of the cannon will go down. When the barrel is down, the tail of the cannon will go up. In this way, the pitch of the cannon will be restricted, and the swing of the cannon tail inside the turret is restricted.
Downwards, it may hit the floor, upwards, it may hit the top of the turret.
Especially for the Soviet tanks, because the turret was originally very low, the angle of the gun tail turning upward inside the turret was limited, and its dive angle was not large. In Western tanks, they could reach ten.
When the angle of the degree is about the left and right, the angle of the Soviet tanks is often at four or six degrees. For this reason, the Soviet tanks also received a special title called the Soviet people never bow their heads.
On the battlefield, tilting corners are also useful, so that you can hide behind a bunker and engage in sneak attacks and hide yourself. In several wars in the oil area, the role of tilting corners is reflected.
When it comes to the wheeled vehicle in front of you, the dive angle and elevation angle of the tank gun have been greatly improved, especially this elevation angle, which is simply incredible.
The higher the elevation angle, the more the cannon tail is, the lower the cannon tail. Now, this way of looking up to the sky means that the cannon tail has hit the floor. How did they do it?
"That's right, it's just a plane." Wang Erzhu said: "It is said that recently, the Army attaches great importance to air defense issues. If our wheeled assault gun encounters an emergency, lift the barrel to masturbate the plane, that's it
It's absolutely fine."
Of course, in this era, it is already very difficult to use gun barrels to hit the plane. After all, if the anti-aircraft gun does not rely on a certain fire density, it will not be able to hit the enemy at all. Therefore, if such guns are used to hit the plane,
There are many difficulties, but they have this ability. In an emergency, you can still deal with the other party's flying helicopters, drones, etc. when loading the radio near-fighting shells to deal with the flying armed helicopters, drones, etc.
"Raise the barrel and it can be used as a howitzer." Wang Erzhu continued: "In this way, it can provide long-distance support to the army."
The most important thing is howitzer.
If the barrel of a tank gun is classified, it should be considered a cannon. In the past era, it was distinguished by the diameter of the tank. The smaller diameter was the howitzer. The flying shells were small at the beginning of the velocity and the trajectory was bent, which was used to perform the
Fire support, while high-caliber cannon shells have large initial velocity and straight ballistics, which are used for direct firing. Tank cannons are all long-barrel high-caliber cannons.
However, with the development of the times, the difference between these artillery is gradually fading. For example, howitzers are comprehensive, and can be used as cannons or howitzers.
The original tank gun could fire grenades, but the elevation angle of the gun barrel was limited, so the range of the grenades fired was limited. Normal howitzers were fired at high elevation angles, and the tanks could not reach it.
Now, this wheeled assault gun can make the barrel high, so that the shells can be hit farther.
"Our wheeled assault guns can reach 17 kilometers if they fire ordinary shells. If they use special bottom-mounted shells or rocket extended-range shells, then there is no problem with the range of 30 kilometers. They can be completely used to give the army a total of 30 kilometers.
Providing fire support.” Wang Erzhu continued.
Qin Zhenhua's eyes were so bright that it was a kind of versatile equipment? He could masturbate on the plane, hit tanks on the bottom, and also provide long-range support. It seems that this thing is a versatile thing and can do anything.
Wait, how did it technically solve it? Qin Zhenhua said: "With such a high elevation angle, how did it solve the problem of its gun tail?"
This sentence was considered as the key point. When Wang Erzhu heard Qin Zhenhua's question, he smiled and said, "I have to thank our Engineer Wang for inventing and perfecting the H-type transmission scheme to turn our wheels.
The bottom of the infantry fighting vehicle was vacant."
This is still the difference between central transmission and H-type transmission. If it is a central transmission, then there must be a transmission shaft and a differential at the bottom of the wheeled infantry fighting vehicle. These must occupy space. If this is used,
If you have a transmission plan, the bottom of the vehicle must be at least 30 centimeters high.
Of course, ordinary wheeled infantry fighting vehicles may not matter, but this type of wheeled assault gun is not good. After all, the bottom of the vehicle is raised by thirty centimeters, which means that the turret must also be raised by thirty centimeters.
Come on, the center of gravity of the entire chariot will move upwards. Not to mention the recoil problem of firing a cannon. Just talking about the fact that the center of gravity is too high when driving, it is easy to overturn.
Therefore, the H-type transmission solution has become the only solution to realize this type of wheeled assault gun. The transmission system is on both sides. The floor in the center of the vehicle body is a layer of steel plate, and the ground is under the steel plate, which greatly reduces the whole
The height of the car improves the utilization rate of internal space.
"It seems that we have decided to adopt the H-type transmission plan?" Qin Zhenhua asked.
When manufacturing wheeled infantry fighting vehicles, the two solutions were carried out simultaneously. Because the central transmission plan was technically difficult, the test run was carried out earlier, and this H-type transmission plan took longer time
However, since the development of the H-type transmission system has shown more and more advantages.
"Yes, we have decided to promote the H-type transmission plan." At this moment, Yang Zicheng, who was standing by, spoke. He used to be a supporter of the central transmission plan, but now he is convinced. The H-type solution,
It is obviously even better. Therefore, the two R&D teams were combined together, and this wheeled assault gun was the crystallization of everyone's work together.
