Just like the fuel consumption of a car is not about the road conditions, these have no practical significance. Speaking of the range of shells, we have to talk about the type of shells.
Generally speaking, there can be grenades, bottom concave grenades, anti-tank mine-branch bombs, bottom exhaust bombs, rocket extended range bombs, FlA cigarette cartridges, flares and bounce observation training bombs, etc. Among them, the range of the gun is mentioned.
The influence is also concentrated on several technical routes.
An ordinary grenade is an ordinary warhead, with brass on the outside and a fuse in front, and a high-explosive inside. When it lands, it relies on explosives to eliminate the target. The larger the caliber, the stronger the power. When it arrives at the warship
The large shells with a caliber of several hundred millimeters used on them can kill all people of the basketball court with just one shot, and their power can be seen.
However, ordinary shells are subject to resistance during flight, especially when the shells are flying, they must rush out the air and move towards the front. The air pressure in front is very high, and the tail of the shell is a blank area, which is flying rapidly
In the middle, the air cannot be replenished in time.
This creates a situation: the air pressure faced by the warhead is very strong, and there is almost no air pressure at the tail of the bullet. In this way, air resistance occurs. This force is preventing the advancement of the shell and slowing down the shell. In the professional field, this is what it means.
It's called bottom resistance.
In this way, some people began to consider that since the low pressure zone at the tail causes the increase in resistance to the shell during flight, then, if I add a special gas device at the tail of the shell and constantly use gas during the flight
Will filling this low-pressure area at the tail of the shell reduce the pressure difference between the two ends and reduce air resistance?
This is the principle of the bottom exhaust bomb, referred to as the bottom exhaust bomb. This method can significantly increase the range of the shell.
But what if this isn't enough?
That is, rocket extended range bombs have to be used. As the name suggests, the principle of this shell is also very simple. The shell's warhead not only contains explosives, but also a small rocket engine!
When flying out, the rocket engine ignites, providing additional thrust to the shells, which will naturally further increase the range.
Compared with the bottom-mounted bomb, it can increase the range longer. After all, it has its own power. However, this shell is destined to be complex in structure and high in cost. Moreover, because of the rocket engine, it will definitely squeeze the space for explosives, so that the explosives can be
The filling amount is reduced and the power is reduced.
Therefore, on the regular battlefield, there are fewer cases of using rocket extended range bombs, but now, if you want to compare the range, it is definitely an advantage for rocket extended range bombs.
You said that your shells can hit thirty-nine kilometers away, so we have them, we can hit 40 kilometers away.
When Best said this, he was still a little proud. If we talk about technology, it is naturally our most advanced one.
"Tender with something that has not been developed yet, Mr. Best, are you all fooling customers like this?" Qin Zhenhua heard the other party's words and looked disdainful: "Whether you can install air conditioners, there is still such increase in the number of people."
Cheng Cannonballs, they are all on your paper. Now we bid to hold the things on the paper. Is it appropriate?"
If you say you can play forty kilometers, then try it out and compete with the data on paper. What's going on?
"Yes, we haven't developed it yet, but this is not a difficult task. In short, it's just better than your thirty-nine kilometers!" said Best.
Now I can only mess around. It’s just like this. Why don’t you accept it?
"If it's better than paper, then we can also take out our paper. Our rocket extended range bomb can hit 50 kilometers." Qin Zhenhua said there.
"You're talking nonsense!" Hearing this, Best immediately retorted: "Didn't you just say thirty-nine kilometers? How could you easily increase ten kilometers? 155mm cannon, fifty kilometers? Who would believe it?"
The normal 155mm cannon in the Western world can only hit twenty kilometers. The early models of the M109 equipped a few years ago could only hit eighteen kilometers, but the other party said they had to hit fifty kilometers, and there was a limit to bragging.
"Our bottom mount bomb can hit 39 kilometers, so why not for our rocket extended range bomb to hit 50 kilometers?" Qin Zhenhua said.
Don’t forget that in the past few years, like the Soviet Union, we advocated militaryism, and we did not fall behind in the research and development of artillery.
Just now, Qin Zhenhua said he would hit 39 kilometers, but the other party thought it was a rocket extended range bomb. Now, Qin Zhenhua solemnly told them that our bottom mount bomb could hit 39 kilometers, and he went on to the rocket extended range.
After the bullet, the range can be increased by 25% or even 100%. So, what's wrong with hitting fifty kilometers?
"You brag, I don't believe it!"
Best said: "I will never believe that your cannons can hit thirty-nine kilometers when they fire the bottom-mounted bomb!"
Our cannon is 39 times the caliber, and 45 times the caliber is just six times the caliber. Multiply by 155, that is, 0.93 meters, the barrel increases by less than one meter long, and the range is
So much has been added? From twenty-five kilometers to thirty-nine kilometers? Who believes it!
Of course it is impossible to only increase the barrel, but don’t forget that Dr. Boer, the artillery madman, has also added a lot of medicine rooms to do anything for the range.
"Don't believe it? If you don't believe it, let's try it." Qin Zhenhua said: "Look at whether we can hit a distance of 39 kilometers when we only use the bottom bomb!"
While there was a noise here, people from Rainbow Country were watching coldly. They knew that it was very likely that they would be a supporting role this time, but they knew their positioning and their own purpose.
Here, they are showing their weapons. Even if the waterless country does not buy them, other countries have opportunities. They just want to seize such opportunities.
Their artillery and the artillery of the Eastern Power were all from Dr. Boer, but they did not expect that in just a few years, the Eastern Power had mastered the technology of this artillery, and even
With performance improvements!
Now, the topic has gone back to the point, and the winning or losing is determined by one shot, which is closer than the range!
"Okay, then try the cannon first." Finally, Ibrahim spoke: "Let's see if the artillery of the great power of the East can be hit thirty-nine kilometers."
After all, when I visited the International Defense Exhibition last year, the other party introduced a range of 30 kilometers. This year, it will be 39 kilometers. There are even 50 kilometers later. It is really exciting.
