Chapter 583 Leader, let me show you a gadget
Walk out of Classroom 61 and say goodbye to the leader of the 12th Machinery Department.
He has to go back to his own territory quickly. Once the integrated circuit is successful, he still has a lot to do.
The leader of the Defense Working Committee is not in a hurry, this is his territory.
Looking at him, Gao Zhendong thought that he could just take a look at the things he brought over.
"Boss, are you free? If you are, let's go to the shooting range. I'll show you a gadget, haha." Gao Zhendong took the initiative to invite.
Hearing this, the leader was very interested. Gao Zhendong's "gadget" may be really small, but its significance is not necessarily small.
"Is there such a good thing? Let's go!"
Not only him, but also a series of leaders from Beijing University of Technology who were accompanying him were also very interested. What's new about Professor Gao? Something?
Gao Zhendong picked up a large bag from the GAZ-69 waiting at the door of the lecture hall. It looked angular and heavy, but in Gao Zhendong's hand, it was as light as nothing. .
The group of people walked to the shooting range of Beijing University of Technology, where Professor Liu from the 61 Gun Clan was already waiting.
Seeing Gao Zhendong coming, he said hello: "Professor Gao, are you here? We are ready as you requested."
Just after he finished speaking, he saw a man behind Gao Zhendong. The leaders came together and were surprised: "Hey, leader, you are here too."
It seems that Professor Gao is going to do something big, even this person is alarmed.
Gao Zhendong smiled and said: "Thank you, Professor Liu, I have troubled you again."
Professor Liu was modest for a moment and pointed to the several light yellow transparent objects in front of him, like jelly: "This is ballistic gelatin. It is better than the soap bar you want, and you can see it more clearly."
< br>I hope I can’t see it, Gao Zhendong thought to himself.
Under everyone's curious eyes, Gao Zhendong took out something from the bag he was carrying.
This is a board. It looks a bit like a chest ring target, but it is smaller than a chest ring target. It looks like it is made of plastic extrusion, but the weight is not noticeable. Mainly Gao Zhendong Due to his strong strength, the thing seemed weightless in his hand, but looking at the texture, it seemed heavy.
The board is slightly curved, one or two centimeters thick, and its width and height seem to be just enough to cover a person's upper torso.
"This is..." The leader's heart moved, and he seemed to have thought of something. The main reason was that the shape of this thing was so recognizable.
Gao Zhendong did not answer directly, but smiled and said: "You will know it just by looking at it."
Needless to say, this is a bulletproof insert.
It is not troublesome to burn this thing, Liu Rongguo moves super fast.
The alumina ceramic hexagonal block is divided into two layers in the insert plate, and the joints between the two layers are staggered to each other. This is to prevent bullets from hitting the joints, resulting in a decrease in bulletproof capabilities.
Gao Zhendong did not have high-strength fiber, so he made a relatively thin 592 rolled sheet as the backing. As for the ABS plastic outside, it was the launch tube material of the 61 fire made by Xiang Zong and others.
The strength and weather resistance of this material are both good. Gao Zhendong had already asked them for a twin-screw extruder and a certain amount of ABS granular raw materials, so that when needed, he could It is no problem to directly process the mold and handle the testing of small workpieces.
Not the best, but it works.
After saying that, he called someone, placed a piece of ballistic gelatin 15 meters away, and then placed a board in front of the gelatin.
He walked back and asked Professor Liu for a gun.
"Give me a 61."
Although he didn't say it clearly, everyone knew what he took out, and they were just curious about how far he could do it.
The most excited person was undoubtedly the comrade from the Land Loading Bureau at the scene. He was here to talk about the 61 Gun Clan. When Professor Liu came here, he just followed suit.
General Manager Gao acted righteously and made spears, and now he is making shields.
Invite everyone to hide behind the bunker, mainly because they are afraid of ricochet flying around, although the chance is very small.
Just as Gao Zhendong was about to go up and fight himself, the leader stopped him and pointed to a comrade who came with him.
"Go!"
Gao Zhendong had no choice but to hand the gun over to him angrily. The comrade took the gun and asked: "General Engineer Gao, how many shots will you shoot?"
"Take a shot first." Gao Zhendong, who couldn't enjoy it with his own hands, was a little listless.
"Bang!" The comrade's movements were very fast. As soon as Gao Zhendong finished speaking, he shot out with a clean shot.
Just kidding, this distance is easy for him.
The gunfire rang out, the bullets were ejected from the gun, and everyone gathered around.
Comrade's marksmanship is very good. He only saw a small hole in the front of the board, almost in the middle.
The front is not important. The leader of the National Defense Working Committee turned the board over without saying anything.
“Hey, it didn’t penetrate!” He looked excited, this thing seems to work well.
It is very obvious that there is a small bump on the back of the board, but there is no sign of a puncture.
He turned to the comrade who fired the gun and said, "Let's go, let's fire a few more shots!"
After a while, several more shots rang out.
A group of people gathered around again, all amazed.
I saw that although there were many bumps on the back of the board, they were not penetrated. Although it looked a bit ugly, it was not penetrated.
After weighing the board, the leader asked: "How much does this thing weigh?"
This sentence is very particular. For bulletproof materials, the lighter the better. Speaking only of bulletproof capabilities, the steel plate dried to a few centimeters thick can still block 7.62*39M43 bullets, but the weight is needless to say.
The ordinary armor-piercing ability of M43 bullets is 100 meters of 6mm steel plate, and a 300*200*6mm steel plate weighs about 2.8 kilograms, and this 2.8 kilograms cannot be defended The M43's ordinary ammunition, let alone the current shooting distance, is only 15 meters!
Gao Zhendong smiled and said: "It's less than 3 kilograms." What's the point? The good products in Level 4 A that I saw in my previous life weighed 2.7~2.8 kilograms.
Even though this is 3 kilograms, and the 6mm thick steel plate is 2.8 kilograms, that thing can't be prevented at all.
This made all the comrades at the scene open their eyes in surprise. This weight has practical value. Even if it is not spread out, it can be inserted into the comrades who are attacking. The weight of less than 3 kilograms is basically It does not affect tactical movements very much. An empty gun weighs more than 3 kilograms.
Gao Zhendong smiled and said: "It's not over yet, I'll try again."
It's not over yet? what else?
Gao Zhendong’s board is designed to protect against 7.62*54R bullets. It is roughly equivalent to level 4 armor according to future American standards.
This is also the most powerful ammunition in the hands of light infantry at this time, not counting the 12.7.
He walked back and greeted Professor Liu's students.
"Shuilianzhu and Dabaliu, give me a handful of the same."
After saying that, he took out two more boards and placed them in front of two pieces of gelatin.
Shui Lianzhu, Lao Maozi’s Mosin-Nagant, uses 7.62*54R bullets. We have bought a lot of this gun from Lao Maozi, so naturally we have it.
Big eight grains, Citigroup's M1 Garand, uses 7.62*63 .30-06 rifle bullets. We have made a lot of this gun, but the method is not very gentle.
These two types of guns are typical of full-power rifle bullets. If they can carry these two, then the goalkeeper who can carry full-power rifle bullets - Ying 77, is not a problem.
Everyone is curious whether this thing can be defended against. These two items are much more powerful than M43 bullets.
The comrade who did the test picked up two guns and fired one shot at each of the two bulletproof plates.
When I looked over, the comrades from the Land Loading Bureau were the most excited.
"It's not penetrated! It's not penetrated!"
The bulge on the back of the bulletproof plate is very obvious, looking like a small hill, but it still has not been penetrated.
“Fight again!” The leader was very excited and wanted to see the limit.
Another burst of gunfire rang out, this time some were penetrated, mainly when repeated hits occurred in a small area.
All the comrades were very surprised by this result, which means that as long as the luck is not too bad, this thing can withstand several shots of water or big eight!
"Three kilograms, it's incredible to be able to achieve this level!"
"That's great. In this way, the lives of our soldiers will be even more protected."
"Listen It is said that Chief Engineer Gao was born in the infantry and has never forgotten his hometown."
"This thing doesn't look big, but it is much more useful than the turtle shell that the little devil used to have."
Hey, this comrade is so well-informed that he can actually see that weird little devil’s turtle shell.
But for the leader, he was a little worried about whether these protrusions could cause fatal injuries.
After thinking about it, he turned to the principal of Beijing University of Technology and smiled: "Do you have live pigs in your cafeteria?"
"Yes!" He answered without hesitation, jokingly, now Catch me and get one for you.
“Catch one and give it a try!”
There really was one at Beijing University of Technology. At this time, it was nothing new for universities and enterprises to run their own pig factories.
Not long after, the second senior brother who was shouting "ouch" was pulled to the shooting range.
Gao Zhendong took out the last bulletproof insert from his pocket and handed it to the comrades from Beijing Institute of Technology.
There was some trouble this time. Although the limbs were tied, the second brother, who was still struggling, could not place the board firmly on his body.
Later, the students found more rope and, under the guidance of the butcher, tied the board directly to the heart of the second senior brother.
The second senior brother also seemed to be tired from struggling. He just lay on the ground, moved slightly and hummed softly.
The big eight pills in the hands of the comrade who was trying to fire made a "pop" sound.
The second senior brother, who had already calmed down, let out a shocking howl like a slaughtering pig.
No, this is killing pigs.
But this long-lasting scream made the comrades present happy, which means that its vitality is still very strong.
The students rushed up, pulled open the rope, and took off the bulletproof insert.
They used the multifunctional bayonet of the 61 rifle to shave off the black hair on the pig.
The situation is very good. The second senior brother is still jumping around. There is obvious subcutaneous bleeding from the impact, but other than this, there is nothing wrong at all.
Everyone waited for another half an hour while chatting about Gao Zhendong’s gadget. It seemed that the pig was in good condition and nothing happened.
At Gao Zhendong's request, the butcher personally went into battle, cut the pig down with a knife, and cut open and inspected the ribs covered by the bulletproof plate.
It doesn’t stop!
