Reborn in 1976, teach him how to be an official

According to Liu Hongyi's initial design, if the launch device and grenade meet the design standards, in light mode, the maximum effective killing distance of the high-explosive grenade can reach more than 1500 meters, and the effective killing distance can also reach more than 1000 meters.

After the grenade explodes, the lethal range can reach 7 meters, and the effective killing range can reach 15 meters.

Armor-piercing grenade can penetrate 400 mm homogeneous steel armor within 50 meters.

When dealing with unarmored civil engineering works and transport vehicles, it is basically possible to hit them with one shot.

It is an absolute weapon to deal with group charges and "human wave tactics".

The rifle's under-barrel grenade is different from the later products that Liu Hongyi is familiar with. The biggest difference is that the caliber is increased by 5 mm, from 35 mm to 40 mm.

Liu Hongyi knew that the reason why our army set the caliber at 35 mm was to distinguish it from the MK79 of the United States and the RGM40 grenade launcher of Russia.

So that others won’t accuse us of “plagiarism”.

Both grenade launchers are 40mm caliber.

But for now, let’s first solve the problem of “whether or not”. Liu Hongyi doesn’t care whether it is plagiarism or not.

I'm a student at Chuzhou No. 1 Middle School. I've never been to either the United States or Russia. Even if I wanted to plagiarize, I have nowhere to go. If you have the guts, prove that I'm a time traveler!

Reducing the grenade caliber by 5 mm means that its power will also be reduced and it will be more difficult to process.

There is no need to set obstacles for yourself.

Just get the 40mm one, bite me!

There are mainly two types of artillery shells with grenades hanging below.

The first one is naturally a high-explosive grenade, and the second one is a smoke bomb.

As for stun grenades, flash grenades, flares, and door-breaking grenades, we will develop them slowly in the future.

After lowering the requirements for the fuse, the sample was finally produced after two failures.

In order to improve the shooting accuracy and armor-piercing performance of the under-barrel grenade, Liu Hongyi designed a muzzle-loading rifled mode. This ensures that the shot is farther and more accurate with a lower muzzle velocity.

At the same time, it can further reduce the chamber pressure required for firing, so that the projectile can be fired with a smaller amount of propellant. The barrel of the launch tube can be made thinner, and the overall weight is reduced.

Rifled design naturally has its pros and cons.

The biggest disadvantage is that when loading the grenade, it must be aligned with the rifling before it can be loaded. The loading speed is not as fast as the smoothbore design, resulting in a lower overall rate of fire.

However, compared with the successful development and production of this product, such disadvantages are naturally acceptable.

The design and production of new weapons are a success.

Privately, there were also undercurrents at Factory 576.

That night, in the valley of Factory 576, a light came on in the window of a bungalow.

This was the residence of Wang Zhigao, Deputy Director of the Revolutionary Committee. Jiang Guoyong, another Deputy Director of the Revolutionary Committee and a member of the Maoist faction, was also there. On the table lay three stir-fried dishes, two cold dishes, and a bottle of Chuzhou Daqu.

The Chuzhou Daqu was already more than half empty, and both Wang Zhigao and Jiang Guoyong blushed, feeling a little interested.

"Zhi Gao, this won't work..."

Jiang Guoyong took a sip of Chuzhou Daqu, smacked his lips and said.

Wang Zhigao glanced at him.

"I didn't expect them to have developed both of these weapons. At first, I thought that old bastard Tan Dexi was just messing around..."

As a veteran of Factory 576, Jiang Guoyong knew that Tan Dexi had previously developed a 40mm underslung grenade launcher, but had to abandon the project due to the difficulty of machining the mechanical fuse.

At that time, Jiang Guoyong was just an ordinary worker. He had also participated in the production of grenades and was quite familiar with the process.

This time, Tan Dexi started working on a small-caliber grenade launcher again. Jiang Guoyong didn't take it seriously at first, and was just trying to have fun, waiting for Tan Dexi to make a fool of himself again.

Who knew it would work this time?

"If this happens, maybe Tan Dexi will come back..."

This is what Jiang Guoyong and Wang Zhigao are most worried about.

They are not afraid of Song Anhua.

Although Song Anhua's prestige in the factory is relatively high, it is not as high as Tan Dexi, who is the real soul of Factory 576. The key is that Tan Dexi has a bad temper and is stubborn.

Wang Zhigao and Jiang Guoyong can deal with Song Anhua, but once Tan Dexi comes back, their days will be difficult.

Although Old Tan couldn't remove the deputy director of their Revolutionary Committee, he couldn't even dream of continuing to lord it over the factory like he was doing now. Many of the old workers in the factory listened to Tan Dexi.

Whoever Lao Tan asked them to "do", they would do it.

Deputy Director of the Revolutionary Committee, that's useless.

In the past, they took advantage of the situation and branded Tan Dexi as "opposing a certain academic authority," sending him straight to the Yanggou Cadre School to work the land. But over the past two years, the tide has turned somewhat, and they can no longer just accuse people of whatever they want as they did before.

Thanks to his great contribution in developing two new weapons, Tan Dexi could implement the policy and return to Factory 576 to continue serving as chief engineer as long as someone from above gave the order.

Wang Zhigao sneered and said, "He wants to, but I, Wang Zhigao, am not a dead man!"

Jiang Guoyong's eyes suddenly lit up, and he quickly leaned over and said in a low voice, "Zhi Gao, do you have any good ideas?"

They all came from the "Xuan-Xuan" faction and were now deputy directors of the factory's Revolutionary Committee, but there was still a hierarchy. Wang Zhigao was the first deputy director. When they were working together on the "Xuan-Xuan Revolutionary Alliance," Jiang Guoyong was also the "second in command," and Wang Zhigao was still the boss.

Jiang Guoyong always listened to him and admired his quick thinking.

"You forgot that his assistant, Liu Hongyi, who's said to be the deputy leader of the research team, is actually just a high school student. I've learned that Liu Hongyi's father, Liu Chuan, is now the director of the Revolutionary Committee and Party Secretary of the Yanggou Cadre School. He was also demoted to the school because he made a mistake. He used to be the deputy leader of the Agricultural Work Leading Group of the Regional Revolutionary Committee."

"That Liu Hongyi, what is his identity? He's neither a technician at the research institute nor from our 576 Factory. I heard he was even expelled from Chuzhou No. Middle School for assaulting someone. How could a traitor like him be involved in such an important research project and even serve as deputy team leader?"

"I've already reported this to Director Kang Jisheng of the Local Revolutionary Committee. He'll send someone to the factory tomorrow to verify it. Let's work together and mobilize some people to write dozens of posters tonight. We'll post them tomorrow morning to build momentum."

"When the time comes, I'll see who dares to protect him!"

"Even Tan Dexi, that anti-revolutionary and old rightist, should be driven back to the Yanggou Cadre School."

"Don't we, Factory 576, deserve the credit for these two new weapons?"

"You are the deputy director of the Revolutionary Committee, and I am also the deputy director of the Revolutionary Committee. This great achievement cannot be left out without either of us!"

Wang Zhigao had a sinister smile on his face and was talking with saliva flying around him, looking very proud.

Jiang Guoyong was immediately impressed and gave him a thumbs up.

"Zhi Gao, it still has to be you!"
