Super military empire

(The new book "Sanjie Tea House" asks, asks for collection!)

Of course, this is not to say that the Ninth Five-Year Plan is really so rubbish. Compared with the foundation that China has, it is considered good, but ergonomics was not considered in the design, which caused many defects.

This is a firearm specially designed for Chinese motorized infantry.

At present, the 77-1 foldable automatic rifle is commonly used in China, but it is only the folding of the butt. There is not much improvement in the overall length of the gun. It is only convenient for armored soldiers to use, not because of firearms. Too long makes the soldiers inside the armored vehicle, causing various inconveniences.

Fortunately, Liu Yijiu didn't wait long, and Luo Tong took the initiative to come to him.

The look on this kid's face shows that he has had a good time these days.

"Did you figure it out?" Liu Yijiu looked at Luo Tong who was somewhat restrained, and asked him.

Li Rui made the tea, then greeted him, and went out to play with the two children.Leave enough space for the two brothers.

"Little Jiu'er, I'm sorry!" Luo Tong did not call Director Liu again, but called Liu Yijiu's nickname.At the beginning, several of them were called that.

Now there is no one named Liu Yijiu, except for some old men at the base.

"Okay, just figure it out. If you are a technical person, you can't let the family drag you down. A few of us brothers, so we can see each other often. You know, I am a special person and I don’t have many real friends. ......" Liu Yijiu confided the truth, even if he and Li Rui were respectful as guests, they still had such a sense of strangeness.

Without too much polite and greetings, I entered the subject facing Luotong, "What kind of problems are facing the problem of small-caliber rifle design? I haven't made a breakthrough for so many years. Let me tell you first, I called Chen Dashan over. , Let’s discuss it together."

Liu Yijiu first called Chen Dashan, and then he had tea with Luo Tong to find out the situation.

"Small-caliber rifle design itself is not too problematic. There is the foundation you left behind, but when designing, especially when we conduct various sample gun tests, there are many problems..."

Luo Tong devoted himself, almost the same concentration as Liu Yijiu.

When I talked about this issue, I kept talking, "The first is the problem of our design. So far, many solutions have been revised, but I am still not very satisfied, especially some details. The ergonomics problem is also a brand new topic. ..."

"The aspect of ergonomics cannot be bypassed in the future firearms. It must be considered when designing. The 77 series, which can be said to be used for emergency situations, did not consider too much when designing. You give the design plan Let me see what the situation is..." Liu Yijiu actually has no experience in gun design.

But he knows the design of many classic firearms.

Therefore, there is no problem with some suggestions for improvement.

"95?" When he saw Luo Tong's design, he suddenly exclaimed.

"What 95?" Luo Tong couldn't help but wonder.

He has worked on this plan for quite a while, and then has been making changes all the time.

"No. This design, have you ever thought about it. Although the front design has a small grip and is integrated with the trigger guard, how should the soldier hold the gun at such a distance?" Liu Yijiu sighed In one breath.

Is Roton the designer of the original Type 95 rifle?

This is impossible.

Now that Luotong has come up with such a plan, what is the design of the gun research institute?

"Indeed, but the entire layout is too compact. I also thought about the layout design in the traditional way, but it would take longer for soldiers to change their magazines. This gun was originally used for assaults by special operations forces. Rifle..." Luo Tong frowned.

Ergonomics is what must be considered in the design of future firearms.

The reason why 95 makes a lot of soldiers despise and prefer to use 81 bars is largely because of this.

"At the same time, with this design, the shooter sticks his cheeks too close to the source of smoke when shooting, and the incompletely burned gunpowder gas overflows from the shell ejection window, the pull handle slot and the upper cover heat sink, which directly stimulates the shooter's eyes or diffuses on the aiming baseline. , And even affect the shooter's continuous aiming and shooting. This situation also brings inconvenience to the use of weapons. It does not meet the requirements of special operations..."

In foreign assault equipment, not many firearms adopt this design.

The m4, mk18, etc. used by the US military are not designed like this, mainly considering ergonomics.There is also the impact of the performance of weapons and equipment on soldiers' combat effectiveness.

95 is not good, the biggest problem is these aspects.

At the same time, there are material problems and the problems that parts are easy to drop during disassembly and maintenance.Even engineering plastics become white after being used for a long time after being blackened, which is a problem.

Even if it does not consider the use of the country's troops, but only special operations forces, such a design will not work.

Chen Dashan obviously attaches great importance to the improvement of firearms. After all, he hopes that his special forces can have stronger combat effectiveness.

It has been impossible to unearth much potential from the soldiers.

To improve combat capabilities, we can only consider weapons and equipment.

"How to say? Can there be improvements?" Chen Dashan asked this when he came.

"What are you worried about? You weren't so worried when you had been using 56 and a half before?" Liu Yijiu gave Chen Dashan a white look. "You come here to ask you to make suggestions and tell the problems you encountered. Even though the experiment has not been completed. , The sample gun has also been used by the army. Only with your suggestions can we design better guns."

Chen Dashan nodded, "I told you about the problem I encountered before..."

"Then I might as well not call you over..." Liu Yijiu was a little speechless, "You guys who use guns naturally have to have ideas too?"

"This is true. Before, the person in charge of logistics collected the requirements of the soldiers. The main thing was to strengthen the distance between the front grips, otherwise the hands could not move forward, and the back smoke source had to be away from the cheeks. Farther, otherwise, during the battle, our soldiers would have to be killed by the enemy just after they had only shot a few shots..." Chen Dashan immediately took out several thick pages of printing paper from his pocket.

All of these are requirements for improvement.

While handing it to Liu Yijiu, he said, "I knew you would need these, so I asked them to investigate clearly these days, and then organize them together."

When Luo Tong saw this, the corners of his mouth twitched, "Lao Chen, you are not kind, you didn't give this to me before!"

Chen Dashan directly despised Luo Tong, "These things were given to you before, but you don't have much thoughts, and there are not many people in your firearms shop. How much have you improved yourself?"

If it is elsewhere, Chen Dashan will consider that he is Liu Yijiu's brother and will not raise this question.

Hearing this, Luo Tong's face turned red.

Liu Yijiu didn't say much, but said directly, "Let's make improvements on this plan. If we need to change all of these, then, first of all, the front grip position must be modified forward. At the same time. To keep the soldiers' cheeks away from the source of smoke and not affect the combat, then the current design of the unsupported structure must be changed..."

While talking, constantly modify the design drawings provided by Luotong.

Luo Tong looked at him and frowned, but he didn't react at all, just frowned.

Even Chen Dashan can't stand it anymore, "I said the boss, how long is this gun if you continue to do this? We might as well use the 77-2. Although the gun has a lot of problems, it won't be too long... …"

"How much does the gun weigh with this design?" Liu Yijiu asked Chen Dashan.

Although the previous Type 77 was also designed from Type 81, Liu Yijiu made a lot of changes for higher accuracy, making the weight of the firearm up to 4 kg, plus the grenade launcher, which is more suitable. Don't need it.

"About 3.5 kilograms." Luo Tong said.

"Isn't engineering plastics used? It's still that heavy?" Liu Yijiu frowned.

The m4 used by the US military weighs only 2.68 kg with an empty gun and only 3.13 kg with a 30-round magazine.Under the same load conditions, American soldiers even carry 60 more bullets than Chinese soldiers!

“The weight of the firearm, especially the empty weight, is best reduced to about 2.5 kg. The overall length of the gun is preferably no more than 800 mm, or even no more than 750 mm. We can’t just consider shortening the length of the firearm. We have to consider the power of the firearm. In this case, we need to increase the kinetic energy of the muzzle to make the bullet eject faster. At the same time, we must have a faster shooting speed..." Liu Yijiu said to Luotong .

Luo Tong saw Liu Yijiu's revised plan, and then he quickly figured out how to incorporate such changes into his shooting.

"Of course, at this time, we can refer to some foreign designs." After Liu Yijiu finished speaking, he didn't say any more. He threw the requirements listed by Chen Dashan Luo to Luotong and asked him to proceed according to the follow-up situation. modify.

Currently they only need to complete the overall design first.

Chen Dashan was also happy, and after robbing Liu Yijiu's home a lot of good cigarettes and wine, he slipped away without even eating.

After Liu Yijiu put forward some suggestions, Luo Tong returned to the design office with the drawings.

After freeing up, Liu Yijiu was scurrying around the base of the Ninth Hospital, making some suggestions for various projects, and waiting for Ye Xuan's return.

Due to the US government's obstruction, it is not easy for many students who have studied in the US to return to China.
