And what about the other two Gatling guns, that is, heavy firepower. Among them, this is still based on the project proposed by Jiang Chen, developed and designed. Do you remember the projectile and cannon integration system mentioned before, these two Gatlings were developed for this purpose? One is a 12.7 mm heavy machine gun line. The other is a 20mm Gatling gun. These two guns, no, and the cannon, were developed for that.

First of all, let's talk about the 12.7mm version, which is the heavy machine gun version. The development of this version is not just about having this anti-aircraft machine gun, in fact, it is very versatile. The entire R&D team envisions that this gun can be installed on this vehicle in the future and used as a high-level dual-purpose machine gun. It can also be used as a stationary weapon on top of a fortified position. Of course, because the weight of this gun is too heavy, it is not suitable for infantry handling and use. Although it can still be handled, it can be disassembled into several parts, transported separately, and assembled when needed. However, the ammunition it needed was a 12.7 mm heavy machine gun, and at this weight each person could take as much as they could. Even if you take too much, how can you withstand this consumption of a minimum launch rate of two thousand per minute. Therefore, this gun was mainly developed for this vehicle-mounted weapon and positional suppressive heavy firepower.

But considering that this 12.7 has limited power. Yes, although it is very powerful, but after all, it is still a bullet, or a gun, and it is still more effective to use it against light targets on the ground, and the infantry is still relatively effective, but when it is used to deal with air targets, the firepower is a little weak. So under Jiang Chen's construction, the R&D personnel have developed a larger caliber Gatling gun, no, it should be said that it is a Gatling gun. After comprehensive consideration, the R&D team chose the 20 mm caliber as the caliber for the Gatling gun. One of these 20 mm is the dividing line between guns and guns, which can be said to be the lowest caliber guns. The other, the 20 mm caliber, is also available in the world and is not original, so it is more suitable for the logistics and supply needs of most countries, and is more conducive to its promotion and sales in the international market. The reason why it was chosen instead of the domestic millimeter caliber was mainly a sales relationship. At present, large-scale disarmament is being carried out in the country, and the economy is vigorously developed. With weapons and equipment like this, Jiang Chen wasn't sure if they needed it. So I still think it's better to study the international version first, such as →dǐng→diǎn→小→ said, .●.o□s_(); If there is a need in China later, we are developing a domestic version, so that we can better avoid risks.

However, although only a few millimeters of caliber have been added, the difficulty of such research has greatly increased. Let's talk about this 12.7 version first, although it is a few millimeters more, but the difficulty has increased several times. First of all, there is the problem of firearm materials, and the materials in different positions also have different requirements. This barrel, for example, had to be made of hard, high-carbon steel. However, as we all know, our country has always been a short board in the development of this special steel. Although with the previous 12.7mm large-caliber sniper rifle research and development experience and technical accumulation, but this is far from enough, the sniper rifle used materials and requirements are different from this heavy machine gun, especially under such a high rate of fire, the test of materials will be more severe. Because to fire a 12.7 large-caliber bullet, this means that the bullet has more ******, resulting in more kinetic energy, and the pressure on the barrel will also increase exponentially. The speed of the bullet is faster, which means that it corresponds to the increased wear and tear of the barrel trajectory. So if there is no hard material, the rifling of a barrel may be smoothed out in a few shots. And the chamber pressure is an important factor in controlling whether the bullet accurately hits the target, if this is gone, then the gun will not be long before it explodes.

There is also the problem of the strength of this gun body, which is also a difficult problem that cannot be ignored. 12.7 large-caliber bullets, which means that the bullet has more ****** and thus produces more kinetic energy. This also means that its recoil will be stronger, and its force on the body of the gun will also be stronger. Moreover, there are many transmission devices on this gun, under such a large force, how to make this transmission device and other parts intact, and how to enhance the mechanical strength of the gun body on the premise of reducing the weight of the gun body, this is also a more difficult problem in front of Jiang Chen and them.

is also lucky, that is, when this large-caliber sniper rifle was developed before, I found a research and development idea for this material. So since then, they have been continuously researching materials with greater strength, better toughness, more wear resistance, and high temperature resistance. During this period of time, there has also been a certain accumulation of results. Therefore, after encountering this dilemma, the firearms room contacted the material research and development room in a timely manner, and quickly got their support. With the support of their materials, the speed of development of this gun has increased significantly, and it will be developed quickly, and then the relevant comprehensive performance tests will be carried out.

However, on this 20mm Gatling gun, the entire research and development work was not so smooth. Again, the strength of the material is not up to the requirements. The 20 mm caliber anti-aircraft shell has a larger charge, so it has a longer range, and the force acting on the cannon is stronger. Therefore, according to the accumulated technical achievements of the current material room, there is still a certain distance from reaching the standard.

I have to say that the wisdom of our people is infinite, and after encountering this technical bottleneck, they did not give up research, but took another path. What's that, it's sacrificing weight to meet this strength requirement. This sacrifice is not about discarding or losing weight, but about adding weight and volume accordingly. This increases the robustness of the parts. However, the price to pay for this is also huge, and the weight and volume of this Gatling have increased significantly, which makes it lose the advantage of being able to maneuver quickly. As a result, researchers have continued to develop materials that emphasize larger sizes, which can then be used to reduce the weight and bulkiness of the Gatling cannon.

Of course, this is a previous thing, and in recent times, R&D personnel have made new breakthroughs in this aspect. First of all, through the cooperation with other domestic research institutions to carry out technology exchange, so that the material room can obtain a relatively strong material. With the introduction of this material, the weight and size of the 20mm Gatling gun will be further reduced. And another thing, that is, the breakthrough of the material real yàn room in the alloy material, which makes the firearms research and development real yàn room is also making a similar attempt, replacing more parts with stronger and lighter alloy materials, and this 20mm Gatling gun is one of them. It is believed that with the use of this alloy material, this Gatling cannon will be successfully developed and put into test equipment sooner. (To be continued.) )
