It's like talking about the fuel consumption of a car and not talking about road conditions, these are of no practical significance, and when it comes to the range of shells, you have to talk about the types of shells.

Generally speaking, there can be grenades, concave grenades, anti-tank mine-laying bombs, bottom exhaust bombs, rocket range extender bombs, FLA smoke bombs, flare shells and bullet observation training bombs, etc., among them, to say that the range of artillery has an impact, it is also concentrated in several technical routes.

Ordinary grenade, that is, an ordinary warhead, the outside is brass, there is a fuse in front, the inside is mainly high explosive, and when it lands, rely on explosives to destroy the target, the larger the caliber, the stronger the power, to the kind of large shells of several hundred millimeters used on warships, one shot can kill all the people the size of the basketball court, and the power can be seen in general.

However, ordinary shells are subject to resistance in flight, especially when the shells are in flight, they have to break away from the air and move towards the front, and the air pressure in front is very large, and the tail of the shell is a blank area, and in the rapid flight, the air cannot be replenished in time.

This creates a situation: the air pressure faced by the warhead is very large, and there is almost no air pressure at the tail of the bullet, so there is air resistance, which is stopping the advance of the shell and slowing down the shell.

In this way, some people began to think that since the low-pressure area of the tail caused the increase in the resistance of the shell in flight, then, if I add a special gas device to the tail of the shell, and in the process of flight, constantly fill the low-pressure area of the tail of the shell with gas, wouldn't it be able to reduce the pressure difference between the two ends and reduce the air resistance?

This is the principle of the bottom exhaust projectile, referred to as the bottom exhaust projectile, which can significantly increase the range of the shell in this way.

But what if that's not enough?

That is, you have to use a rocket range extender projectile, as the name suggests, the principle of this shell is also very simple, the warhead of the shell not only has explosives, but also a small rocket engine!

When flying out, the rocket engine ignites, providing additional thrust to the shell, which naturally increases the range even further.

Compared with the bottom row bomb, it can increase the range longer, after all, it has its own power, but this kind of shell is destined to have a complex structure and high cost, and because of the rocket engine, it must squeeze the space of the explosive, so that the filling amount of the explosive is reduced and the power is reduced.

Therefore, on the regular battlefield, there are relatively few cases of using rocket range extender bombs, but now, if you want to compare the range, it must be that rocket range extender has an advantage.

You say that your shells can reach a distance of 39 kilometers, then we have them, and we can reach 40 kilometers.

When Best said this, he was still a little proud in his heart, and when it came to technology, it was naturally our most advanced.

"Bidding on something that hasn't been developed yet, Mr. Best, are you all fooling customers like this?" Qin Zhenhua heard the other party's words, with disdain on his face: "Whether you can install air conditioners or have this kind of extended-range shells, it is all on your paper, now let's bid and take the things on paper, is it appropriate?" ”

You say you can fight 40 kilometers, then try it with a shot, and compare it against the data on paper, what is going on?

"That's right, we haven't developed it yet, but it's not a difficult thing, in short, it's stronger than your thirty-nine kilometers!" Best said.

Now it's just messing around, that's how it's compared, what's the matter, not convinced?

"If it's on paper, then we can also take out what we have on paper, and our rocket range extender can hit up to 50 kilometers." Qin Zhenhua said there.

"You talk nonsense!" Hearing this, Best immediately retorted: "Didn't you just say thirty-nine kilometers? How is it possible for you to easily add ten kilometers? 155 mm guns, hit fifty kilometers? Who would believe it? ”

The normal 155-mm guns in the Western world can only hit 20 kilometers, and the early models of the M109 equipped a few years ago can only fight 18 kilometers, but the other side says that it will fight 50 kilometers, and there must be a limit to bragging.

"Our bottom-row bombs can hit 39 kilometers, so why can't our rocket range extender hit 50 kilometers?" Qin Zhenhua said.

Don't forget, in previous years, like the Soviet Union, we all advocated the doctrine of the Continental Army, and we did not lag behind in the research and development of artillery.

Just now, Qin Zhenhua said that he would hit 39 kilometers, and the other party thought it was a rocket range extender bomb, but now, Qin Zhenhua solemnly told them that our bottom row bomb can already hit 39 kilometers, and after getting on the rocket range extender bomb, the range can be increased by 25 percent or even 100 percent, so what is there to do if it hits 50 kilometers?

"You brag, I don't believe it!"

"I would never believe that your artillery can hit 39 kilometers when it fires a bottom row," Best said. ”

Your own cannon is 39 times the caliber, and the 45 caliber cannon, but the difference is only six times the caliber, multiplied by 155, that is, 0.93 meters, the barrel has increased by less than a meter, and the firing range has increased so much? From twenty-five kilometers to thirty-nine kilometers? Who believes!

Of course, it is impossible to only increase the barrel, but don't forget, Dr. Bull, an artillery maniac, can do anything for the range, and the medicine room has also increased a lot.

"Don't believe me? If you don't believe me, we'll try. Qin Zhenhua said: "Let's see if we can hit a distance of 39 kilometers with only the bottom row of ammunition!" ”

At the same time as the noise here, over there, the people of the Rainbow Country have been watching coldly, they know that it is very likely that they will come to play a supporting role this time, but they know their own positioning, and they also have their own purpose, they come here to show their weapons, even if the waterless country does not buy it, other countries also have a chance, they just want to seize such an opportunity.

Their artillery, and the artillery of the Eastern Powers, are all from the hands of Dr. Boole, but they did not expect that in just a few years, the Eastern Powers have mastered the technology of this artillery, and there is actually an improvement in performance!

Now, the topic has come back to winning or losing, and winning or losing is more than the range!

"Okay, let's try it first." Finally, Ibrahim spoke: "Let's see first, whether the artillery of the eastern powers can hit 39 kilometers." ”

After all, when I went to visit the International Defense Exhibition last year, the other party introduced a range of 30 kilometers, and this year I came to show it again, and it was already 39 kilometers, and there was even a 50-kilometer version in the later stage, which is really exciting.
