For the troops, it is not a big problem to have a heavier tripod. If you put on a heavier tripod, it is for battalion. Heavy little bit is not a problem. However, as a light machine gun configuration for a company machine gun, the weight of the gun body is very high, and the troops only recognize a number - 7.5kg mentioned by Chief Engineer Gao.

If we don’t recognize anything else, we just recognize this 7.5, can’t we do it? That's your problem.

This puts Zhao Gong, who already has a certain understanding of PK machine guns, into a dilemma. He originally thought of thinking about a solution at the beginning, but after getting the PK, he found that things were not simple.

This gun is very well done. It means that it is difficult to start anywhere, and you dare not change it here, and you dare not change it there.

Only then did he realize the value of Chief Engineer Gao. How could he be sure to have a way to change it to 7.5kg? The difference of 1.5kg is not something that small surgery can solve the problem.

He was also very curious about how Chief Engineer Gao would change this thing.

Gao Zhendong pointed his hand at the front of the gun: "Swap this thing."

He pointed to the long barrel.

Hot Knowledge, PK/PKM's barrel is a bit bigger than similar equipment.

Mr. Zhao was a little surprised. Can the barrel be replaced at will?

"General Manager Gao, do you think this gun barrel is too long?"

This is the only explanation. The length of the barrel of this gun is indeed exaggerated. What's amazing is that the overall length of the gun is okay and acceptable.

Gao Zhendong laughed. How could it be shortened? The troops disagreed as the first one. Within a certain limit, the length of the barrel is directly linked to accuracy, power, and range. If there is no barrel, it depends on luck to kill a 12.7mm heavy machine bullet. The 9*19mm pistol bullet can only scrape.

As the same as the Russians, we are afraid that the power and range are not enough. If you cut off the barrel, the first thing you are anxious about is the army.

Gao Zhendong shook his head: "No, no, no, let's thin it."

"Flipping? Can the strength be withstand it? Look, the reinforcement ribs in the second half of the barrel can take into account the heat dissipation function. If it is too thin, not to mention whether the strength is enough, but heat dissipation is a problem, right?" Professor Liu also joined the discussion. He knew that Gao Zhendong was a material, so he was not too entangled in strength. If Professor Gao took out another material with his backhand, he would not be able to talk about it.

However, the heat dissipation is solid. No matter what steel, the heat conductivity and specific heat capacity are similar. If there is less material, the heat dissipation will be weaker. This is impossible to avoid.

Gao Zhendong said: "Yes, there is no need to worry about the strength. As for heat dissipation, it will be affected. But this gun has a removable barrel."

The removable barrel of PKM has always been a core point that has been criticized, which is that it feels that the heat dissipation is not good and the replacement speed is slow.

In fact, this cannot be said to be completely wrong, but it cannot be said to be correct. Anyone who has seen PKM's barrel change knows that changing barrels is indeed not fast, but it is definitely not slow. It can be replaced within 30 seconds. If it cannot be replaced, then you have to find the reason for your training.

In fact, there are two more steps to change the barrel of PKM than to remove the barrel quickly. Open the cover and then open a cover under the cover. These two steps are about breaking the clip. Then you can use the handle to beat the barrel to the side and pull it out.

It looks very cumbersome, but compared with the "quick removable barrel" of Hans MG42, which doesn't want to change without gloves, it's hard to say who is faster on the battlefield.

The disassembly and assembly structure of the PKM barrel is related to the overall structure. It is really not easy to modify it. Otherwise, PKP would not have taken a different approach to solve this problem, so Gao Zhendong had no idea to modify it. This thing is good if the Russians and mainland army patients use it, but it doesn’t matter what others say.

In fact, our heavy machine gun has a similar structure. Changing the barrel requires opening the bullet cover, but it is not a big problem for the 12.7 heavy machine gun and PKM heavy machine gun mode that does not require close contact.

As for the light machine gun mode that is close to each other, the possibility of shooting a red tube is not that great. The close fight is an explosion, but it does not require long-term success.

Moreover, if you want to say how much you can carry this kind of barrel with reinforcement and heat dissipation tank, it may not be possible. When the battle is fierce, it will be hot, and it may not be much better than changing the tube quickly.

"It can be removed the barrel...it seems to make sense." Gong Zhao and Professor Liu looked at Gao Zhendong skillfully disassembling and installing the gun barrels, and felt that the speed seemed to be quite fast.

This can save at least one kilogram, and with the spare barrel, it is at least two kilograms, which is not a small amount.

"And..." Hearing Gao Zhendong's words, Gong Zhao might not feel anything, but Professor Liu's eyes lit up immediately, and Chief Executive Gao must have a backup plan.

"What else is there to do? Mr. Gao."

Gao Zhendong drew out the only design on the PKP he was planning to learn from.

"You can design such an air duct that uses hot air to flow and force heat dissipation. This design was quite common in previous light machine guns."

Simply put, add a layer of iron tube with a window at the tail to the outer periphery of the barrel, forming an air duct with the barrel, and use the gunpowder gas during shooting to force the cold air to dissipate heat.

That's how PKP does it, but PKP removes the replaceable barrel function and moves the bipod from the gas regulator position to the muzzle. In the end, this improvement was criticized very much. Forced heat dissipation, this thing is not new, so Mr. Zhao and others understand.

"But in this way, the gun may gain weight, right?" The most important thing about this gun is to lose weight.

Gao Zhendong laughed: "You can try the lightweight barrel + removable, and the forced refrigeration barrel of the induction fire cannot be replaced, and the forced refrigeration barrel of the induction fire fire should be made. Several solutions have been modified and will be given to the comrades in the army. They will naturally know what they want. Let them choose the heavy or lighter."

In experimental research, it is impossible to take out the finished product directly at any time. It is rare for Gao Zhendong to do things against the will of heaven. Generally, multiple plans are compared.

"Hey, yes, yes, this method is good. We all do it to the extreme, and then ask the comrades from the army to choose."

In fact, Gao Zhendong is still confident that they have improved the total gun weight of the shooting barrel according to their own improvement. The PKP is 8.2 kg, but Gao Zhendong is confident that what they made can reach below 8kg, because the materials they have in their hands are much better than those of the Russians.

Except for parts like bolts that cannot be reduced at will, it should be no problem to pick up a little more or less weight, such as bipods.

"By the way, this butt stock part, I suggest you find someone, ask for high-strength engineering plastics, and use engineering plastics as a butt stock."

Compared with PK's original wooden butt stock, engineering plastic is a better choice, with much higher strength, and wood is expensive. The old men once liked to use good wood on guns, which was heavy and expensive, but they were not as durable as engineering plastic.

The high-strength engineering plastics produced by Mr. Xiang and others have been used in many places such as the plateau and snowy areas, and have proved that they have good performance and can be used as butt stocks.

The newest ⊥Xiao⊥Speak⊥Send⊥Six⊥9⊥Book⊥⊥⊥⊥Back⊥⊥⊥⊥!

"Okay." Not to mention Mr. Zhao, even Professor Liu thought this idea was good, although he didn't know what his gun and butt stock looked like now.

Everything was communicated almost the same, so Gao Zhendong turned to greet the Beijing University of Technology students at the shooting range.

"Classmate, come on, give me a few more cables."

All the bullet link machine guns can be called logistics fun instruments. Gao Zhendong is preparing to make the logistics comrades of the Beijing Institute of Technology happy.

This is called loading for ten minutes and splashing water for ten seconds.

This is a new imported weapon, and I have to help my comrades test it carefully.

——

As the beginning of the new year of the Gregorian calendar, there are naturally many things that need to be carried forward and open up the past.

At this time, a comrade in charge of science and technology committee members in a certain place in the capital was watching the recommendations of various ministries and commissions.

The science and technology committee members are very interesting. The recommendations in natural science are relatively concentrated, but due to the large number of technical branches in technical science, the recommendation votes are very scattered. Basically, each of them is in charge of their own, and they have almost no understanding of those outside their respective fields.

This made it impossible for scientific committee members of the technology science to be selected through industry recommendations. In the end, there was no way to change the method, and the Academy of Sciences and Technology discussed with leaders of various ministries and commissions, and finally selected the list.

What they were looking at at this time was the list pushed by various ministries and commissions.

"Haha, they finally couldn't help it, so they pushed this comrade out." A comrade smiled.

Another person heard this and stretched his head over to look at the name on his hand, and smiled: "It's natural. If you drag it out, it will lose objectivity. Whether it's for protection or anything, you can't continue like this. A laser from two years ago is basically enough."

"He has achieved many qualified results. Has he been delayed until now considering his family situation?"

This committee member has three requirements, which seem very simple: academic achievements, contributions to the cause of science and technology, and a cause of loyalty to the masses.

Although the people here do not know all about Gao Zhendong's situation, they only know the part, and the first two items are sufficient. But what each of them knows about Gao Zhendong is different. It can be said that you want the city gate tower, and I want the hip axis.

As for the third item, some people know more or less about Gao Zhendong's family situation, especially from the Medical Department.

"Impossible, he...he...is very strong." This comrade should have known something, hesitated for a moment, and used a very vague statement.

Someone laughed and said, "It's far more, but his situation is not suitable for discussion. We should focus on the election of scientific committee members." This person should be a leader and knows a lot.

"Yes, yes, but now there is a big problem with him. Do you think about how to solve it?"

The other comrades were very surprised. What big problems could this comrade have? It's impossible.
