In fact, adding length to the barrel of a tank gun is originally the easiest way to increase the power of a tank gun.
The shells fly forward, and the speed increases all come from the work of high-pressure gas inside the gun barrel. When the shells are pushed out, the remaining gas will fly out of the muzzle, forming a fireball at the muzzle.
These energy have actually been wasted, and the fireball that came out still contains huge energy.
If you want to continue to use this energy, you must lengthen the barrel and continue to allow the shells to receive the push of high-pressure gas inside, so that the speed can be further increased.
So, if you consider it from this perspective, the longer the tank gun barrel, the better.
But considering the actual situation, it has to be combined. Although the longer the barrel, the more work the launching medicine will do, the longer the barrel, the heavier the barrel will be.
This is a very important indicator. After all, the turret needs to rotate. If the barrel is too heavy, it will not rotate too fast. In this way, in an emergency, it will not be able to quickly aim and shoot.
On the other hand, the obstacles encountered during the journey are that the barrel is too long and will be more obstacles when traveling in some dense forest areas. Therefore, these restrict the unlimited increase in the length of the barrel.
Now, we have introduced the original L7 tank gun. If we want to loosen the export of this tank gun, we have to change it.
My purpose of coming here is to solve this problem.
To increase the length and solve the so-called export barrier, for the people in Yimai Factory, it seems that a crack was suddenly split in a dense dark cloud, and the golden light shone down, in everyone's heart,
They all began to become warm.
"Yes!" Ma Panshan slapped his thigh at once: "Our self-developed tank gun is our self-developed tank gun! Mr. Zhu, tell me, how can we change it?"
Mr. Zhu was originally a famous artillery expert, but now his empty sleeve was because of an accident during the shooting test. Now, he, the artillery expert, was in charge of himself, so naturally to preside over this specific improvement meeting.
I have been confirmed to be modified, so how to change it?
"This change must be cautious, so today we are going to brainstorm. At the same time, I will go to the Second Machine Factory to discuss it with the capable generals of the Second Machine Factory for the second time." Mr. Zhu said.
When designing a tank gun, it must have gone through many compromises. Now, the British L7 tank gun can become a NATO standard, which must be expedient in all aspects. If you change it, then
It's going to destroy this balance.
It may change the better, or even worse?
"Zhenhua, tell everyone what you think?" At this moment, Mr. Zhu spoke.
The idea for this change was proposed by Qin Zhenhua. Now that he sat at the end, he still couldn't escape Zhu Lao's eyes. Zhu Lao was looking forward to Qin Zhenhua talking about his ideas.
"Cough, cough." Qin Zhenhua cleared his voice and said the second sentence, which was even more surprising than the previous sentence.
"If I were asked to say something, add five centimeters, how about it?"
Everyone's eyes were about to fall off.
The artillery is based on the diameter. Now, the tank guns imported from the UK are already 51 times the diameter. If we want to change, we have to be longer, for example, to change to 56 times the diameter or even 60 times the diameter.
?
What do you mean by adding 5 cm? This is not even 1 times the diameter!
(East China's hero has checked a lot of information, and the statements of various information are different, even contradictory. This is of course due to the fact that the British L7 tank guns were too classified. Many of the information were directly used for the later L7 tank guns.
According to the data, the length of this gun is close to 6 meters. This is obviously not the data from the tank guns exported to us in the 1970s. After all, when we improved to the Type 94, it was only 6.3 meters. It is said that the L7/M68 type was introduced.
, Without finding this data, I took the L7A3 tank gun of Leopard 1 tank, which is 51 times the diameter, which is about the same length as our Type 83 tank gun, which should be the length of the early L7 tank gun, and,
Type 83 is a modified extended version. As for how much it has been lengthened? It is definitely not as long as Type 94, so just take 5 cm. If you have any major knowledge of the specific data, please give the East China Majesty a correction. Domestic information is too confidential
OK, no way to find out.)
Mr. Zhu showed a look of praise.
"Different lengths of the body tube will have different ballistic characteristics. After we rashly lengthen, it will definitely bring about great changes in other data." Qin Zhenhua said: "So, now we only need to solve the problem of export agreements and lengthen them a little bit.
Five centimeters will not have much impact on the ballistics, so it will make it easier for us to correct the shooting meter. This is also the easiest problem to solve at present."
Extending the barrel to obtain greater power is the way the tank gun develops. However, different lengths mean different ballistic characteristics, which means that the fire control system must be adjusted accordingly. In this way, it is estimated that it will be
I can't catch up with the export to Lao Ba.
People won't wait for their own side to struggle for several years.
Therefore, Qin Zhenhua proposed this plan. Let’s add five centimeters first, play word games with the British, export and make money first, and let’s talk about what’s going on in the future!
"If we consider it from the long term, in order to further increase the penetration depth, I suggest that we can increase the length of the barrel to more than 6 meters, so that we can greatly increase the armor-piercing ability. After all, for us, there is no deepest
, only deeper, of course, this plan probably takes ten years.”
For military research and development, ten years have not been long. I have been working on 100 slips for more than ten years. As for the planned 120mm smoothbore cannon, I have also made mental preparations for a protracted war.
Zhu Lao nodded: "Yes, this is also my idea. After we introduced the original L7 tank gun, we produced at low speed and understood the technology while conducting innovative research and development, and completely turned into our own products. At the same time, in order to solve the export problem.
The problem, so, divide it into two parts: short-term goals and long-term goals.”
Mr. Zhu was very satisfied with Qin Zhenhua's analysis, just like his own thoughts.
"Recently, we have only changed slightly to avoid the agreement. In the long run, we must increase the length of the body tube to increase the power of this tank gun by more than 50%. Once our self-developed 120mm smoothbore gun has problems, we will still
You can come up."
Zhu Lao stood tall and saw far, and after improving his power, he was also a substitute for his own 120mm tank gun. After all, the risk of self-developed self-developed is still very high.
After some research, we unified our thoughts and established our confidence again.
"Zhenhua, call me, the old man, over from all over the world, but in the end, I didn't seem to have done anything." After the discussion was made, Mr. Zhu couldn't help but sigh.
