Thank you for the generous reward of Feng Dongliang Dada for two 588 coins, thank you for the generous reward of 150721153254100 588 coins, and thank you for the generous reward of Bing Zhihen. The editor has confirmed that this book will be available on the first day of next month. If you think this book can still be seen by brothers, save the reward money for subscribing to support it.

There will definitely be a burst update. I originally planned to be a burst update of 100,000 words, but it seems that there is not much possibility. Because of some things, the manuscript of Hulu has been abandoned. Of course, it is still early now. There is no decision on how much it will explode and how it will explode. Brothers who have ideas can suggest it!

·············

Liu Yijiu really didn't expect that there would be so many technicians in District 3. And they were all over 30 years old, and the young ones didn't see them at all!

Xie Heping and the others are really okay. They have so many people, but they can only give themselves three of them. It is simply too much. If they really have to design everything from beginning to end like other firearms institutes in China, they have to be designed and experimented, even if they give them dozens of technicians, they may not be able to design them in three years!

"There is no problem with the process. However, according to the current situation, the weight of the sniper rifle will be much higher than that of the magazine and bullets when assembling the sniper rifle. The service life of the barrel will be much lower than that of the designed one..." Yu Jianguo shook his head and introduced the situation to Liu Yijiu.

In order to save costs, trial production is used to obtain parts by mechanical processing.

No matter how hard the parts produced by mechanical processing are, they cannot achieve the surface processing quality of medium-pressure parts. It doesn’t matter if the gun cartridge is, but the service life of other parts is not as high as stamping parts.

"This is for sure. But the processing weight should not be too heavy, right?" Liu Yijiu asked with a frown.

"When you design the components of this gun, most of the structural parts are prepared to use stamping structures, right?" Seeing Liu Yijiu nodding, Yu Jianguo further said, "The stamping parts are stamped with cold-drawn plates with high surface roughness. The processing stress is relatively small and the processing deformation is smaller. However, during the cutting process, stress will be constantly generated..."

"How much will it weigh?" Liu Yijiu asked with a frown.

For the Type 77 12.7mm reverse equipment sniper rifle, Liu Yijiu modified some sniper rifles that are more in line with the use habits of ** based on the US Bartre M107. The muzzle retractor adopts the cylindrical design of the M107A1, which not only effectively reduces the recoil during the design, but also reduces the gunshot and muzzle fireworks when the bullet is out of the bore.

The total gun is 1326mm long, the barrel length is 680mm, the designed effective range is 2,000m, the total gun weighs 11.85KG, the capacity of ammunition is 10 rounds, and there is no mechanical sight. There is no sample of the sight yet, but Liu Yijiu requires that the weight cannot exceed 1.5KG. In other words, the theoretical design weight after the scope is installed shall not exceed 13.35KG! For each special forces thirty kilograms of weight, this is not too heavy.

After all, the bullets are carried by snipers and observers around them separately, and with other weapons and equipment, they do not exceed 30 kilograms.

"About one kilogram, after the original modification, didn't we leave the design drawings to you for signature?" Yu Jianguo said speechlessly.

When they were processing, they found that it was difficult to achieve the processing according to Liu Yijiu's requirements. During the mechanical cutting process, it was difficult to prevent the parts from deforming, especially in the current ordinary mechanical processing equipment.

Liu Yijiu was busy getting other gun drawings at the time, but he didn't ask in detail, and directly signed the design change form that Jianguo took.

But I didn't expect such consequences.

"And, this is just for the purpose of achieving the weight of strength. When stamping parts are used, the weight will still drop." Yu Jianguo comforted Liu Yijiu.

"Master Yu, this is not the case. The gun magazine and other components are much thicker. When we do various compression resistance experiments and other experiments, the parameters we obtain are basically not very useful..." Liu Yijiu was speechless.

If this thing changes slightly, the real data cannot be tested.

There is no problem with the experiment now, so it will definitely not work if it is replaced with thinner stamping parts. Then I have to conduct the experiment again...

"What should we do now? Just take this as the basis. When mass production is later, stamping parts also use sheets of this thickness? Or should we reprocess them now?" Yu Jianguo was speechless.

If I had known it, I would have had a good talk with Liu Yijiu at the beginning. I was about to pretend. Now that such a problem occurs, no one can do anything about it.

"It is not necessary to use a thickened gun magazine, and the production cost will also be increased. Not only will the material weight be higher, but the mold requirements will be higher, and the mold opening cost will also increase accordingly..." Liu Yijiu shook his head. Since he was wrong, he could only reprocess it.

"But if we reprocess, although we only processed five samples, which cost less than 10,000 yuan, it would have to be a lot of time at night..." Yu Jianguo knew that what Liu Yijiu needed most now was time.

"There is no time. In terms of gun design, we must be more cautious. If a kilogram of load is replaced with other equipment, we can carry more ammunition and individual rations, which will allow our snipers to improve the battlefield survivability. Even if the mission fails, the weight load of one kilogram can be reduced when retreating, and the soldiers can run faster and farther..." Liu Yijiu said firmly.

If this happens, it will never go on like this.

These heavy sniper rifles were originally intended to prepare for special forces and reconnaissance forces. Ordinary combat troops generally do not issue such weapons.

"Now, we all have to bear this consequence..." Yu Jianguo said with a wry smile when he heard Liu Yijiu's words.

"Fortunately, we only produced five of them this time, and it was only our own project. We did not report it. The funds were our own. We had little loss. Otherwise, I really don't know how to explain it. I immediately negotiated with the production side to re-fille these gun cartridges..." Liu Yijiu had no room for negotiation on this matter.

I really don’t know how Yang Shan and the others stared at this.

Liu Yijiu himself also had a responsibility for this, and he could not blame them. He had to give up the plan to invite Yu Jianguo to drink in the evening. The people from the technical department immediately held a meeting to discuss the processing plan, and he also gathered Yang Shan and others together to hold a special review meeting.

"This incident sounded a wake-up call for us. Under no circumstances, if the theoretical analysis and experiment were not conducted, the design could not be modified at will. I am wrong with this. But why didn't anyone realize this problem when you three people tracked production and communicated with the technical and technological department and the production department? We produced guns. Do you know what this aggravated kilogram means to soldiers?" Liu Yijiu first made a self-examination, and then said very seriously to the three apprentices below.

"Xiao Liu, this matter was discovered early. You are usually busy. Anyway, it did not cause any big impact. In addition, the bullets have not come out now, so these gun boxes can be reprocessed. The loss is less than 500 yuan. Just remember to teach a lesson in the future..." Xie Heping and Wang Shunyi were called over.

The other components are processed according to the design, and there will be no problem after the gun magazine is modified. The five lost gun magazines are mainly material costs, tool consumption, labor, and equipment wear can be ignored, and one is the heat treatment cost...

"Director, this is not just a matter of a few hundred yuan. I ask for punishment..." In order to make Yang Shan and others realize that all the links in weapon design and processing must not be careless. This is not the production in previous years, and it will be almost over.

Even Xie Heping and others had the inertial thinking that was ahead.

Liu Yijiu can't say anything about this kind of thinking now. The country will begin to pay attention to this matter until the border self-defense counterattack that occurred next year due to firearm quality problems and caused huge losses to the troops.

Even then, there will be such thoughts in the coming decades.

It is impossible to affect the whole country now, but it can influence the people around him.

"What kind of punishment is it? As a firearm designer, it's not a problem with your design. Besides, weren't you busy at the beginning?" Zheng Hao didn't know which kid was making a fuss. This was obviously a problem for himself.

I have to offend a lot of people.

"Director, we must not relax at all in the weapon design. If we still have the same attitude as before, we will eventually cause some irreparable consequences. None of us can bear this responsibility!" Liu Yijiu shook his head firmly, without taking advantage of Zheng Hao's steps.

Wang Shunyi understood what Liu Yijiu meant and nodded in praise, with the legacy of his father!

"Let's do this, we are all responsible for this matter. I was careless when I was responsible for the review. I also have the responsibility. Xiao Liu signed the design and revision opinion. Yangshan’s few people were not supervised properly, and each person was deducted a half-year bonus to make up for this loss. In addition, just report internal criticism, don't expand this matter. After the use of the seven-special agreement, the quality problems have been reduced a lot..." Wang Shunyi also knew that there would be no benefit if this matter continues like this.

If there are significant losses now, it will not be easy to smooth out.

The problem mainly occurs in their project team, which has nothing to do with the technical and technological department and the production department, so there is no need to bother with these things anymore.

"Everyone has no objection, right?" Zheng Hao glanced around and saw that Yang Shan and the others were dissatisfied and asked them.

"No objection!" Even if Yang Shan and the others had opinions, they knew that problems with the weapon design were not just a joke. The three of them should bear greater responsibility, but Liu Yijiu took the responsibility to them.

This modification plan is the result of the discussion between the three of them.
