Chapter 952

The season has entered autumn, but it has not yet reached the time when the leaves become withered and yellow and a large number of leaves fall with the wind.

Located in the south of Chang'an, near the Qinling Mountains, there is a small military camp on the edge of the mountains.

The existence of the barracks is to block the surrounding areas. Looking at the perfect blockade lines and the pass leading into the Qinling Mountains, it is not difficult to imagine what facilities do not want to leak.

"Your Majesty." Zhang Shi, holding a rifle in his hand, said: "this rifle is improved on the basis of the twelve types. The length of the gun body has not changed, the weight of one kilogram has been increased, and the caliber has been reduced to 14mm. Its barrel has been changed into two styles: linear bore style and smooth bore style. After testing, its accuracy and range have been increased."

To put it bluntly, it is a breech gun, which should have reached the level of the middle of the 15th century.

"The barrel is spiral and linear." Ma Zihuan is an expert. He introduced in detail the results of the changes in the barrel structure. Later, he commented: "after repeated tests, the spiral barrel is obviously superior to the straight barrel."

Liu Yan's attempt at guns has not been completely abandoned despite the years.

Of course, the spiral gun management office will be better than the straight barrel. The spiral barrel can make the long lead shot rotate when firing the projectile, and the flight is stable after being discharged, which improves the firing accuracy and increases the range.

There is a machine tool next to everyone. Naturally, it can't be driven by electricity, but it uses animal power.

The most conspicuous part of the machine tool is the drilling rod, which itself is a spiral style. When drilling, spiral lines will be left in the barrel.

In terms of the current scientific and technological level, such machinery should adopt the best hydraulic power, but it is not easy to find a suitable river first. The machine tool has been successfully developed for less than half a year. For the time being, a suitable section has not been found, so it is temporarily set as an animal style in Qinling.

Two or three years ago, some craftsmen were able to make the barrel of the barrel by hand, but the yield was not high. Moreover, there were too few craftsmen who could do this. No matter how low the output was, it didn't matter if they became a "toy" for several people, but as a gun that needed to be packed, it was too few.

Liu Yan just put forward an idea, the Shaofu made the greatest efforts to study and test, and developed the machine tool after three years.

The new machine tool placed in this factory in Qinling is unique at present. After trying, it can drill up to five barrels a day, and the yield is four barrels. It can be said that the yield is a little frightening.

"If it is changed to hydraulic drive, Chen estimates that the efficiency can be increased by about twice." Ma Zihuan already knows what dynamics and what efficiency a machine can play. Generally, it is a drive decision: "it takes half a month to manually make a threaded barrel. Chen deeply feels the gap between manpower and machinery."

There is only one new machine tool, but it does not mean that there is only one machine tool in the country. For example, before building an ordinary gun barrel, machine tools were also used. Those machine tools are divided into animal power and hydraulic power.

Some previous scientific research achievements are the basis for ensuring the renewal of generations. Any science and technology has indeed become more advanced from generation to generation. Unless there is any miracle, it is impossible to throw stones at people for a while, but the next moment it is launched with Gauss guns.

Accumulation is an inevitable process for science and technology. In fact, that process is also to understand the elements, and then extend all kinds of science. Only a variety of scientific research achievements can combine a product.

"This rifle was named 'twelve style modification'." Liu Yan took the rifle. Generally, there was no big change. He compared a gun shooting posture: "the longest range is 920 meters?"

"Your Majesty, yes." Zhang Shi said modestly, "the accurate shooting range has reached 280 meters."

Liu Yan remembers that the emergence of rifles has changed the playing method of shooting in rows. Soldiers holding rifles are no longer in a close formation. They are in a loose array. They make use of the range advantage. They are no longer close to each other and shoot together. It is a playing method of retreating when the other party can shoot to their own distance.

Liu Yan, the first person to let soldiers with rifles become snipers, has forgotten that after the first one did so, the war in the firearms era entered a new mode. After repeated sniping, no commander foolishly went to death.

"Your Majesty." Zhang Shi asked pleasantly, "do you want me to bring gunpowder?"

Liu Yan really wanted to shoot himself. He came to the shooting range and loaded the ammunition skillfully. After that, he made a standard gun posture and aimed at the gun target 100 meters away. When he pulled the trigger, his body felt recoil, and a "pa" sound came from his ear.

In the distance, a mounted target made a "poof" when the projectile hit, and a burst of dust and smoke was soon dispersed by the wind.

Someone lifted the target. The hole in the center of the gun target ring shows that Liu Yan hit it very accurately, which also proves that this twelve style modification can be used as a sniper gun.

"Try 150 meters." After cleaning the gun bore, Liu Yan was doing ammunition loading: "maybe the butt of this gun should be changed and lengthened by about three centimeters?"

The person holding the notebook nearby immediately recorded it.

What's the use of making a three centimeter change in a gun? That's a question for people who don't know what to do.

Not to mention guns, even if it is a war knife, a little change will produce different hand feel.

The length or length of the gun, and even the weight of the gun, can give full play to its power when it reaches the most reasonable design.

The feel of holding a gun is very important for the shooter, even if it is only a little more comfortable when holding a gun. With different thoughts and feelings, the posture is more reasonable, and each shooting can be more accurate.

Otherwise, you don't have to distinguish between standard equipment and customized equipment. For example, in modern sports, who will use standard equipment will spend a lot of money on customization.

After loading, Liu Yan once again became the standard gun holding position, but he maintained the aiming action for a longer time than the previous time. He was not only aiming at three points and one line, but also observing the plants around the gun target.

Whether a gun is accurate or not, not only considering the gun itself, but also more testing the gunman, at least we should understand that the wind direction and wind force are also one of the factors that can be accurate.

Liu Yan observed the plants around the wall to determine the wind direction and wind force. When aiming, he adjusted the aiming device to make the three points and one line change.

The adjustment of gun parts is a very professional move. For example, aiming at a 100 meter target and a 200 meter target, the aiming device must make subtle adjustments, and corresponding adjustments should be made for different wind forces. Otherwise, shooting a 100 meter target will meet the standard, but the same three-point line shooting a 200 meter target is a lot biased.

Although the standard device of the twelve type transformation is an adjustable mode, it does not have a professional scale, and it still requires users to have sufficient knowledge and common sense (proficiency). Although it is just to add a scale, it is only such a small part, and the time required by the current scientific and technological level is absolutely not short.

With a sound, Liu Yan's body swung back. After he shot, his eyebrows frowned.

After the target was lifted, the hit position was within the seven rings. Although Liu Yangang frowned, he did not mean to appreciate the rifle.

Whether he can fight accurately is not only the quality problem of guns, but also the reason of shooters. Liu Yan will not deny the excellence of guns with his own mistakes.

Liu Yan was obviously not a person who gave up after one unsuccessful experience. He fired twice later and stopped the test firing only after hitting the tenth ring.

There are professional test shooters in the shooting range. They have been waiting nearby. When they see that Liu Yan can hit the tenth ring in just three shots, they show an expression of worship whether he is pretending or not.

After the three test shots, they took turns to test fire, 50 meters, 100 meters, 150 meters, 200 meters, 250 meters and 300 meters. The farther away the target is, the lower the accuracy is. In a total of 30 shots, the best result is to hit the third ring of the target at 300 meters, which is largely luck.

After the test firing, the test firing personnel will evaluate the firearms in a professional direction, and the recorder will record them one by one, trying to do the best.

There were evaluations and records. The accompanying military generals and schools lined up to test fire. It seemed that they had a good time.

"It's excellent." With a smile on his face, Liu Yan said to the generals who watched the whole process and shot himself: "excellent shooters should be selected to use this weapon."

"Your Majesty is right." Huan Wen just test fired a 50-200 meter target. Although he didn't hit ten rings, his performance was not too bad: "it is a weapon that can kill the enemy on the battlefield."

Ran min didn't play with fire less. He shot several times just now, and the worst result within 200 meters was to hit the eighth ring: "I thought the flint gun was powerful enough. I didn't expect that it would be so terrible to change the barrel."

The emergence of firearms will certainly change the way of war. The simplest thing is that the value of force will be reduced. An expert who has worked hard for decades will die if shot, and a person who does not know any fighting skills will die if shot. The value of immersing himself in practicing fighting skills will become a matter of little significance.

Xu Zheng saw the bitterness on ran min's face and didn't want to comfort him at all.

With the change of the form of war, the simple bravery has little effect. What can reflect the value is in the art of command and all kinds of experience.

In short, the history of relying on simple military courage to obtain meritorious service will soon pass, and those who fail to keep up with the pace of the new era are doomed to be eliminated.

"Your Majesty." No matter what the mood of the military general was, Zhang Shicai asked Liu Yan, "do you want to visit the next place?"

Liu yanneng guessed that there must be some new achievements in the ordnance research and Development Department of Shaofu, so that Zhang Shi would ask such a question.

They left this rifle range and did not go far to another range.

It is also a shooting range, but the location needs to be changed, just because the shooting range is also different. For example, rifles and artillery shoot at the same time, and the shooting distance and attack degree are different.

Liu Yan thought he would go to the gun test site. Unexpectedly, the place he came over was also a gun range. He didn't have time to have any doubts. His eyes saw a big guy in the test position.

It was a multi barrel instrument with a base supporting the barrel. It looked both strange and ferocious as a whole.

"You got it!" Liu Yan will be surprised that the guy is infinitely close to the Gatling machine gun, but it seems much larger. He approached the hanging bullet chain and asked Zhang Shi, "can bullets be produced in mass?"

The flint gun also needs to carry out the steps of charging and projectile, and then evolution is the post loading gun.

The emergence of cartridge bullets is a revolution in the evolution of firearms, so that rifles no longer need gunpowder and bullets to operate separately. It should not appear until the 18th century, and it has been developed and matured again and again, and finally become a modern bullet style.

The bullets loaded into the bullet chain are about four centimeters long. Liu Yan goes to the next table, picks up a bullet neatly placed, observes the whole, and finds that it is no different from his own requirements. After disassembly, the cartridge case, primer, propellant and warhead are fully equipped.

"Your Majesty." Zhang Shi looked embarrassed: "the maximum output can be 1300 hair a day."

If a person or a machine can produce 1300 rounds a day, it will indeed be a very good result. The key problem is that the relevant institutions of the whole Shaofu have such efficiency.

"Still improving..." Zhang Shi seems to have to look to Ma Zihuan for help: "continue to improve, and the master knows more."

Liu Yan nodded expressionless to Zhang Shi and looked at Ma Zihuan.

"Your Majesty, I have found out the manufacturing process." Ma Zihuan was full of confidence: "the new machine tool has been successfully developed. As long as we can develop special parts, we will be able to increase the output."

To do something, there must be special parts. The Han Empire now has no shortage of metal. What it needs is to accumulate on the road of science. As long as there is enough perseverance, diversified talents and sufficient funds, the pace will never stop. On the contrary, it will go faster and faster because of the continuous accumulation of basic science.

Liu Yan was regarded as a big guy of machine gun. It started shooting under the operation of professional personnel.

There is no pulling the trigger, but the operator constantly shakes a handle. Each shaking is a primer firing of the bullet, and then presents the explosion and lasing process of the bullet.

Under the constant "click click" movement, the distant target was torn to pieces, but the big guy became dumb in less than 20 seconds.

"This is..." the professional engineer checked it and reported with sweat: "it's stuck."

Just now, most people were stunned. They knew that the ferocious weapon still had major defects. On the one hand, they were relieved and more regrettable.
