Chapter 583 Leader, let me show you a little gadget
Walked out of classroom 61 and said goodbye to the leaders of the th Ministry of Machine Building.

He had to hurry back to his own territory. Once the integrated circuit was successful, he had a lot of things to do.

The leader of the Defense Work Committee was not in a hurry because this was his territory.

Looking at him, Gao Zhendong had an idea that it would be a good opportunity for him to take a look at the things he brought.

"Leader, are you free? If you are, let's go to the shooting range. I'll show you a little gadget, haha." Gao Zhendong took the initiative to make an invitation.

The leader was very excited when he heard this. Gao Zhendong’s “little gadget” might be really small, but its significance might not be small.

"There's 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 new things did Professor Gao have?
Gao Zhendong carried down a large bag from the GAZ-69 that was waiting at the entrance of the classroom. The bag looked angular and heavy, but in Gao Zhendong's hand, it was as light as a feather.

The group walked to the shooting range of Beijing University of Technology, where Professor Liu from the 61 gun family was already waiting.

Seeing Gao Zhendong coming over, he greeted him: "Professor Gao, are you here? I've prepared everything according to your request."

Just as he finished speaking, he saw a group of leaders behind Gao Zhendong and was 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 am sorry to trouble you again with my matter."

Professor Liu was modest and pointed to the yellowish transparent objects in front of him, which looked like jelly. He said, "This is ballistic gelatin. It's better than the soap you asked for. It can be seen more clearly."

I hope I can’t see it, Gao Zhendong thought.

Under everyone's curious gaze, Gao Zhendong took something out of his bag.

This is a piece of board. It looks a bit like a chest ring target, but is smaller than a chest ring target. It seems to be made of one-piece plastic extrusion. The weight is not very obvious. It is mainly because Gao Zhendong is very strong. This thing looks like weightless in his hand, but looking at the texture, it feels heavy.

The board is slightly curved and about one or two centimeters thick. Its width and height seem to be just enough to cover a person's upper torso.

"This is..." The leader's heart moved, as if he had thought of something, mainly because of the shape of this thing, which was too recognizable.

Gao Zhendong did not answer directly, but smiled and said, "You will know when you see it."

Needless to say, this is a bulletproof plate.

This thing is not difficult to burn, and Liu Rongguo is super fast.

The alumina ceramic hexagonal blocks are divided into two layers in the plug plate, and the joints between the two layers are staggered. This is to prevent bullets from hitting the joints, resulting in a decrease in bulletproof capability.

Gao Zhendong did not have high-strength fiber, so he used a relatively thin 592 rolled sheet as a backing. As for the ABS plastic on the outside, it was the material used for the 61 fire launch tube that Xiang and his team had made.

The strength and weather resistance of this material are both good. Gao Zhendong had long ago asked them for a twin-screw extruder and a certain amount of ABS granular raw materials, so that when needed, they can directly process the mold and there is no problem in coping with the testing of small workpieces.

Not the best, but it works.

After saying that, he called for someone to place 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 the gun.

"Give me a 61-gun."

Although he didn't say it explicitly, everyone knew what he took out, and they were just curious about how far he could go.

The most excited person was undoubtedly the comrade from the Land Equipment Bureau who was present at the scene. He was here to discuss the matter of the 61 gun family. Since Professor Liu came here, he just followed along.

Chief Engineer Gao was so righteous that he created the spear, and now he is creating the shield.

Ask everyone to hide behind the cover, mainly to avoid ricochets, although the chance is very small.

Just as Gao Zhendong was about to go up and fight himself, his leader stopped him and pointed at a comrade who came with him.

"You go!"

Gao Zhendong had no choice but to hand the gun to him in dismay. The comrade took the gun and asked, "Chief Engineer Gao, how many shots do you want to fire?"

"Let's shoot first." Gao Zhendong was a little listless as he couldn't have fun with his own hands.

"Bang!" This comrade moved very quickly. As soon as Gao Zhendong finished speaking, he fired a shot cleanly.

Just kidding, this distance is easy for him.

After the gunshot, the bullet was ejected from the gun and everyone gathered around.

The comrade’s shooting skills were very good, and he only saw a small hole almost in the middle of the front of the board.

The front side is not important. The leader of the Defense Work Committee flipped the board over without saying a word.

"Hey, it didn't penetrate!" He looked excited. This thing seemed to be quite useful.

It was very obvious that there was a small bulge on the back of the board, but there was no sign of a hole.

He turned to the comrade who had fired the gun and said, "Go, go, go, fire some more shots!"

After a while, a few more gunshots were heard.

A group of people gathered around again, all marveling at the sight.

Although there were many bumps on the back of the board, none of them were pierced. Although it looked a bit ugly, it was not pierced.

After weighing the board, the leader asked, "How heavy is this thing?"

This sentence is very particular. The lighter the bulletproof material, the better. If we only talk about bulletproof ability, then if the steel plate is made several centimeters thick, it can still block 7.62*39M43 bullets, but the weight is not worth mentioning.

The normal armor-piercing capability of the M43 bullet is 100 meters of 6mm steel plate, and a 300*200*6mm steel plate weighs about 2.8 kilograms. Moreover, this 2.8 kilograms cannot defend against ordinary M43 bullets, not to mention the current shooting distance, which is only 15 meters!
Gao Zhendong smiled and said, "Less than 3 kilograms." What's the big deal? The good stuff in the level 4 armor that I saw in my previous life weighed 2.7 to 2.8 kilograms.

Even though it weighs 3 kilograms, and 6mm thick steel plate weighs 2.8 kilograms, it is still not enough to defend against it.

This made all the comrades present open their eyes wide in surprise. This weight has practical value. Even if it is not spread out, a piece can be inserted into the comrades who are attacking the enemy. The weight of less than 3 kilograms will basically not affect the tactical movements. An empty gun weighs more than 3 kilograms.

Gao Zhendong smiled and said, "It's not over yet, I'll try again."

Not finished yet? What else?
Gao Zhendong's board is designed to protect against 7.62*54R bullets. According to the later American standards, it is about level 4 armor.

This is also the most powerful type of bullet in the hands of light infantry at this time, 12.7 is not counted.

He walked back and greeted Professor Liu's students.

"Give me a handful of both Shui Lianzhu and Da Baliang."

After saying that, he took out two more boards and placed them in front of the two pieces of gelatin.

Water-fired bullet, the Russian Mosin-Nagant, uses 7.62*54R bullet. We got a lot of this gun from the Russians, so of course we have it.

The big eight-grain M1 Garand of the Citigroup uses the 7.62*63 .30-06 rifle bullet. We also got a lot of this gun, but the means were not very peaceful.

These two types of guns are typical of full-power rifle bullets. If they can withstand these two, then the goalkeeper of full-power rifle bullets, the English Type 77, will be no problem.

Everyone is very curious whether this thing can be defended, these two are much more powerful than M43 bullets.

The comrade who was testing the shooting picked up two guns and fired one shot at each of the two bulletproof plates.

Looking over, we saw that the comrades from the Land Equipment Bureau were the most excited.

"Not through! Not through!"

The bulge on the back of the bulletproof plate was very obvious and looked like a small hill, but it was still not penetrated.

"Hit again!" The leader was very excited and wanted to see the limit.

Another burst of gunfire was heard, and this time some were shot through, mainly due to repeated hits in a small area.

All the comrades were very surprised by the result, which meant that as long as the luck was not too bad, this thing could withstand several bursts of water or eight big bullets!

"3 kilograms, it's incredible to be able to achieve this level!"

"Great! This way, the lives of our soldiers will be more protected."

"I heard that Chief Engineer Gao was originally an infantry soldier and he has never forgotten his hometown."

"This thing may not look big, but it's much more useful than the turtle shell the Japanese used to use."

Wow, this comrade is very knowledgeable. He can actually see the strange turtle shell of the Japanese devils.

But for the leader, he was a little worried whether these protrusions could cause fatal damage.

After thinking for a while, he turned to the president of Beijing University of Technology and said with a smile: "Do you have live pigs in your cafeteria?"

“Yes!” He answered without hesitation. Just kidding, I’ll catch one and get one for you right now.

"Catch one and give it a try!"

There really is one in Beijing University of Technology. At this time, it is not uncommon for university enterprises to run their own pig farms.

Not long after, the second brother, screaming "Ah Ah", was pulled to the shooting range.

Gao Zhendong took out the last bulletproof plate from his pocket and handed it to his comrade from Beijing University of Technology.

This time there were some problems. Although his limbs were tied up, the board could not be placed steadily on the second brother who was still struggling.

Later, the students found more ropes and, under the butcher's guidance, tied the board directly to the second brother's heart.

The second brother seemed to be tired of struggling. He just lay on the ground, moving slightly and humming softly.

The big eight-bullet gun in the hands of the comrade who was testing the gun made a "bang" sound.

The second brother, who had been quiet, let out a terrifying howl like a pig being slaughtered.

No, this is killing pigs.

However, the prolonged screams made the comrades present very happy, as it meant that it still had a lot of vitality.

The students rushed forward, pulled the ropes apart, and removed the bulletproof plates.

They used the multi-functional bayonet of the 61 rifle to shave off the black hair on the pigs.

The situation is very good. The second brother is still alive and kicking. There is obvious subcutaneous bleeding caused by the impact, but other than that, there is nothing wrong.

While everyone was chatting about Gao Zhendong's little gadget, they waited for another half an hour. It seemed that the pig was in good condition and nothing was wrong.

At Gao Zhendong's request, the butcher personally took action, cut the pig down with a knife, cut it open and checked the ribs covered by the bulletproof plate.

Not broken!
