Chapter 299 Super Fire Rate

Peng Yixing's firearms modification workshop has a relatively complete set of tools. After all, Peng Yixing not only uses this firearms modification workshop to modify guns, but also uses this workshop to produce high-charge bullets!
The strong charge is naturally to add more propellant to the original bullet, so that the bullet will shoot out of the barrel faster. Of course, this also means greater recoil.

But this is what Peng Yixing wanted, because Peng Yixing specially used a spring with a faster rebound speed in order to pursue the continuous firing speed of the firearm most. It means that the speed of the back seat is faster, and the combo can be played very quickly.

Of course, the process of modification is naturally to draw the design drawings first, and after all, Bailixiu knows the principle of AN94, so the speed of drawing the drawings is also very fast.

After that, it is natural to process the parts required in the drawings.

But at this time, Bailixiu's super precision talent came into play. Bailixiu directly took out the indestructible Xingyun carving knife, and carved out the parts of the firearm with just three strokes and five divisions.

This operation stunned Peng Yixing on the side, and then asked Bailixiu:

"Where did you get the carving knife in your hand? It's so sharp, can you get me one?"

Naturally, Bailixiu couldn't explain to Peng Yixing that it was made by opening the box in Chaowan Space, so she said:

"I bought this from a street vendor. It is said that it was dug out of the soil. I also found an expert to identify it. The expert said that it seems to be some kind of meteorite! Therefore, if you want me to get a second one, I can't do anything. !"

When Peng Yixing heard what Bailixiu said, he naturally didn't say anything more, after all, a gentleman doesn't steal people's love!
Of course, what surprised Peng Yixing even more was that the parts made by Bailixiu's hands were of very high precision, which was a grade higher than those made by high-precision machine tools.

After Peng Yixing assembled the parts of the firearm, he couldn't find the gaps between the parts without looking carefully.

bang bang!

Bai Lixiu's ears burst from almost one shot, but Bai Lixiu only pulled the trigger once after two shots.

However, what made Bailixiu feel the difference was that the impact points of the two bullets did not form a bullet hole as imagined, but a difference of more than ten centimeters.

Just when Bai Lixiu felt a little overwhelmed by the difference, Peng Yixing who was on the side said:
"Remove the muzzle suppressor and try it!"

And Bai Lixiu's eyes lit up when he heard Peng Yixing's words, and he also understood the reason why the impact point was so large, and the reason was naturally the muzzle suppressor.

You must know that the original function of this muzzle suppressor is to open a few holes above the muzzle so that the high-speed airflow of the gunpowder sprays upward to generate downward force, which can offset the problem of the muzzle jumping up after the pistol is fired.

But now the AN94 version of the pistol in Bailixiu's hand, because of the movement of the slider, the second shot has been fired before the recoil of the first shot reaches the wrist.

However, the muzzle recoil of the first shot did not reach the wrist, so naturally there would be no muzzle upward. In this way, the downforce generated by the muzzle suppressor would naturally cause the muzzle to press down without the offset of the upward force. The distance between the bullet holes formed by Lixiu's two shots was naturally larger.

Of course, the solution is naturally very simple, just cancel the muzzle suppressor.

After canceling the muzzle suppressor, Bai Lixiu was very satisfied with the result of the gun test again.

If the bullet holes left by the two bullets are not carefully identified, they may be thought to be the bullet holes of one bullet!
Although the shooting effect met Bailixiu's expectations, Bailixiu still wanted to know how long the interval between the two bullets was. Fortunately, the gun shooting hall is well-equipped and has a special speedometer for testing the fire rate of firearms.

The principle is naturally very simple, that is, use a row of infrared light, and then use the first bullet to trigger the infrared light to time, and stop when the second bullet triggers the infrared light, so that you can get the shooting time interval of the two bullets .

zero thirty one
zero thirty one
zero thirty two

zero thirty two

zero thirty one
Bai Lixiu conducted five consecutive double-shots and found that the average interval between the two bullets was [-] seconds.

Such a shooting time interval also means that the rate of fire of this gun has exceeded the 94 rounds per minute of the AN[-].

You must know that even the AN94's extremely fast two-shot burst is just to make the time interval between the two bullets reach 94 seconds.However, the pistol version of the AN900 produced by Bai Lixiu and Peng Yixing in partnership has a time interval of only [-] seconds. If it is converted into a rate of fire per minute, it has reached [-] per minute. Too many hairs.

Of course, the rate of fire of this is naturally not comparable to that of a multi-barreled rotary machine gun like Gatling, but this is a single-barreled firearm!

At present, the artillery with the fastest rate of fire is the 1130 close-in anti-aircraft gun, with a maximum rate of fire of more than 1 rounds per minute.The AK630 close-in anti-aircraft gun equipped by Ross has a maximum rate of fire of 5000 rounds per minute.However, it should be noted that the modern near-anti-gun system uses a design similar to the Gatling design in which the barrel moves and the barrel does not move. When firing, only one tube is firing, and the others are rotating in line. Wait to fire.So if you want to calculate the rate of fire of a single barrel, you need to divide the maximum rate of fire by the number of barrels.

Therefore, the 11 near-anti-cannon with 1130 barrels has an average rate of fire of 1000 rounds per minute. Ross's AK630 near-anti-cannon has 6 tubes, and the average rate of fire per tube is 833 rounds.Because at present, whether it is a firearm or a gun barrel, its highest single-tube limit rate of fire is 2000 rounds per minute, and there are still no guns and cannons that exceed this value until now.Therefore, in order to increase the rate of fire, it is necessary to combine multiple barrels in order to increase the burst rate of fire of the artillery.

The so-called burst rate of fire is the maximum number of bullets fired by the artillery within a given short period of time, usually 10 to 30 seconds.The greater the density of firepower formed in this way, the more shells fired per unit time, the wider the killing area, so as to increase the probability of hitting the target and the probability of damaging the target.As the last trump card in the naval air defense system, this high-firing near-defense gun can intercept incoming anti-ship missiles in a short time.

For example, the single-barreled rate of fire of aviation machine guns can reach up to 1500 per minute, and the maximum rate of fire of the German MG42 general-purpose machine gun during World War II can also reach 1200 per minute. , and the reason why the single-tube rate of fire of the near-anti-gun is not high is mainly due to the limitation of the bomb supply system.The near-anti-gun system belongs to the external energy revolving tube gun. In theory, as long as the external energy is large enough, the rotation speed of the barrel will be higher, and a higher rate of fire can be achieved in theory.However, if the speed of the gun barrel is higher, the movement speed of the matching ammunition system will be greater, and the mechanical system of ultra-high-speed movement will often fail frequently, making it difficult for the ammunition supply system to supply ammunition in time, so this will also affect the revolving tube. The reason for the low rate of fire of weapons.
