Not good for the armor-piercing? You can't do that。
The impact of head-loading can be much better than that of ammunition in general, although there are still some critical technologies that have not broken down, which has led to some delay in replication。
So we'll give you an example。
First of all, let's say, what's a head bullet
It is also known as embezzled ammunition or cartridges, and even a small partner who has not heard of it can probably know what it looks like。
The ammunition we often see, his warheads are at the front end of the entire munition, and the propellants behind his ass are packed in a metal cartridge。
And where's the bullet? The shape is similar to that of an easy-to-hear can, where the entire warhead is hidden in a cartridge, shrunk into the shell like a turtle, and the side of the warhead is packed with propellant。
So how does he shoot? This is a two-stage launch, so the side of the buttock is a side charge, while the propellant package is called the primary charge。
When the first level of equipment is fitted, the fire starts with a primer, which ignites the auxiliary propellant, which can immediately put the warhead to the top of the chamber and then follow the auxiliary charge to burn, thereby lighting the primary charge。
Once the main charge is ignited, it enters into the second stage of the launch, and the gas that is burned is then released to the top of the barrel of the gun, thus achieving the firing of the munition。
And what good is this ammunition
That's a lot of good。
First of all, the same type of munition, which is buried in a head bomb of a shorter length than the normal munition and, if a shellless or plastic shell is used, the amount of ammunition is lighter than the normal munition。
That alone, his benefits are self-evident。
Shorter length means that when such ammunition is carried, limited space can be inserted into more munitions. A lighter weight would have allowed the carrying of 120 rounds of ammunition, and 200 rounds of ammunition could have been carried without one infantry。
You don't doubt that, do you
This is also a gun, and the benefits are even greater if the technology is extended to artillery。
The shorter length of the head is such that the ammunition boxes will be more compact and the speed at which the shells will enter the chamber will be faster, meaning that the speed of firing will increase。
And when the length is shorter, it also means the same gun, which you can plug in with more propellants when the pharmacy remains unchanged。
That's not very intuitive, so you'll understand。
Take the leadArmour-piercingCome on。
The armour-piercing bullet in his head was fixed in the front of his warhead with a tight ring and a closed-air nylon belt, and the tail was supported by a star-shaped support。
The size of a 40-mm penetrating bullet, which is just a 25-mm automatic gun, do you know what that means
The 25- to 30-millimeter cannon in the active vehicle can be retrofitted directly to a 40-millimetre-calibre head bomb, the power of which will be broken, and you will consider the concept of doubling fire。
Moreover, in the current state of research, the whole of the beam was virtually plastic except for warheads and charges。
Another set of data you'll understand。
The size of the munition used with the head bomb would be about 30 per cent less than the normal ammunition, and the weight could equally be about 30 per cent less. Don't look at this 30% and 30%, but he's got 30% overall performance。
This does not count, as the cost of ammunition is reduced by the use of plastic parts. His cost has been reduced by 40 per cent throughout the life of the weapon system (at last, a figure of not 30 per cent!)
We're talking about his first speed and range。
Take as an example the 40 mm radiant tail-stabilized de-hull penetrators。
The first speed of a head-bursted gun was 1640 metres per second, and that rate was maintained at 1400 metres per second when the warhead flew over 2,000 kilometres。
If the core were to spend money using long dry tungsten alloy, a target of 5 km could easily penetrate。
Speaking of which, we have to ask, why does that work
Because the length of the buried head is reduced, we can increase the diameter of the buried head, so the size of the pill becomes larger, and the load goes up。
The warheads buried in the head are lighter than the normal munitions, and the propellants go up, the initial speed of the warheads will inevitably increase and the range will increase。
That's fine, because it's a two-stage ignition, when the auxiliary charge pushes the warhead into the chamber. After that, the absence of warheads in the pharmacy left more room for the combustion of the primary charge, at which point the primary charge could be applied to the pressure process。
So in this series of changes, isn't the cannon going at a much faster rate than the regular one
Of course, there's a lot of that, and there's no intuitive impression, and you'll see the next few data sets。
The cannon energy of the 40 mm head was 15 per cent higher than that of the same conventional ammunition。
The capability of armour-piercing is twice as high as that of normal ammunition of 25 mm, which is the result of the replacement of the 40 mm skull with a normal ammunition of 25 mm。
What about the lethality? The power of the 40 mm head was six times greater than that of the 30 mm howitzer. Even more surprising to you, his backseat has become smaller, only nine tons, two thirds of the 25 mm automatic gun。
There is another difference from the general ammunition, which, after firing a shell, you have to draw the shell and open the cannon to the back。
It's not as loud as that. It's not a shell. It's not a shell
Finally, the metal cylinders are going to swell at the time of launch, and this expansion is also an attack on the artillery itself for a long time。
The cartridges used to bury the head are small, so it's cheaper for the bomber, and the entire structure becomes simpler. You know, in the field, any kind of mechanical device means being reliable。
Why is ak-47 so popular? You need to know that ak-47's powerful recoil makes his superstar unstable, but because his structure is simple and reliable, he still has traces of this guy。
In other words, it is assumed that the problem of the subject is no longer self-defeating, so that there is no reduction in the charge, but more。
Then how did he get here
This is something that the americans have come up with, and we have to live with it, because the american military equipment ideology of the last 1950s and 1960s, and even the 1980s, is so advanced that much of the equipment is actually coming from that time。
By the time of this century, it was felt that the american people were a little bit weak, not to say that he had something ahead of him, even though he was afraid to publish it。
Why? Because his front foot was published, and the back foot was designed and implemented according to his concept。
It's embarrassing that we've made everything in his way and that americans are still crouching about their conceptualization。
That's a little far. Let's move on to the headshot。
In other words, in the 1950s, the united states air force suddenly had the idea of reducing the ammunition for the cannons and machine guns to a little bit。
According to this idea, they start to think about what their own ammunition is, or reduce it, and you're talking about reduction. Or is it a reduction charge? Or just drop the fire
The fact that the warhead is responsible for the killing of the opponent must not be reduced, the fact that the bottom fire is responsible for the ignition, even more so, can only be reduced by a small amount of propellant, less can be fired and less firepower。
Then, to figure out the size of the munition, if we narrow it down, we'll just have to put the warhead in the propellant。
So this introduces the concept of head-loading, and, of course, the subsidiary practice, which he does not have in time。
By the 1980s, the united states army had begun to wonder about the firepower of their infantry combat vehicles, how to give them a far greater range of artillery and greater penetrating power。
At that time, they had conducted an analytical study of the performance of the various munitions of 30 to 35 mm calibres。
In the end, they were able to figure out a way to combine the head-burst theory of the 1950s, which led to the introduction of a 45 mm shell-piercing project。
See, these research programmes prove, once again, that the subject was fundamentally wrong about the impact on the armour-piercing bomb as a result of a reduction in the number of charges fired。
What do you mean? Plans are often good and prospects are usually good, but they are often defeated by reality。
In the view of that time, the general ammunition was sufficient, so the input in the area of head-bombing would certainly not be too great, i. E., head-loading would have been available for a long period of time because of financial problems。
Of course, it wouldn't have been that way if you had been completely interrupted, at least the american army arms research, development and engineering center had been financing an american company called the elliott technology system。
Of course, these funds are just for him to sustain, not for development。
For example, from 1954 to 1957, funding for three years was $9. 1 million, with the highest period between 1985 and 1988, three years spent $75 million。
By the end of the 1990s, it had reached a low level, with investments at $2-3 million every three years。
After all, it's new ammunition, too much change, and hundreds of millions of dollars have been thrown into it。
Of course, as americans were studying this thing, france joined the group from the 1980s, and the british also joined the group in the 1990s, when the two families were jointly developed。
This joint venture, known as headbone international, has now developed four headblasts, long-barrel armour-piercing, anti-aircraft armour-breaking, grenades with coded fuses and corresponding training rounds。
Don't look at the british and the french as being behind the americans, but in practical terms, the joint development of english and french is better than that of americans。
In 1998, in connection with this joint anglo-french project, a ct2000 40 mm head-burst weapon system was created and the first gun was also tested。
By the end of 1999, the system had been installed in the united states of america's bradley vehicle and had been successfully tested with no fire。
Speaking of which, we have to say that americans like to eat what's available。
Finally, there is a status quo in which head bullets are buried。
The most famous is the technical upgrade of the british samurai, whose main project is the installation of head-loading weapons systems。
The project was carried out by the british-french consortium, which was to deliver to the british army in 2006 the first weapons system of 40 mm head-loading。
If the vehicle's experimental effects are satisfactory to the british army, they will be purchasing the 40 mm head-burst weapon system。
As far as success is concerned, it's a long time ago
That's why chief can't give you a positive answer。
In any case, there's a little bit of data in the author's hand, and you can look at it alive and see how powerful it is。
Since head-laying munitions are more shaped than conventional munitions, and are cylindrical and not sophisticated, the same ammunition chamber can carry half of the same calibre of ammunition and increase its lethality by 40 per cent。
With only two seconds to load with a delivery machine, the system can also pick ammunition from a screen, and within three seconds the system can select the type of ammunition by command。
So one round of ammunition is stuck in the chamber for up to five seconds, while the fastest and seven seconds of manpower, which is no longer than 10 seconds long, is not enough。
So from these data, you can see the power of the head bomb, but there are some technologies that need to be broken
What do you mean? At present, to improve precision and combat effectiveness, the british-french consortium intends to develop a guide to the project, which began as early as 1999, and to place the guidance and flight control technology of the star-light anti-aircraft missile in the project with the aim of making it an anti-aircraft weapon。
So head-laying constitutes a future direction in the area of ammunition, and so far the head-laying has been divided between shelled and shellless。
