A professor's rebirth: I entered Tsinghua University in 1977.

Time flies and it is the end of August.

The development and sample production of new weapons have achieved gratifying results.

The launch mechanism for the 35mm automatic grenade launcher has been developed, as have two types of shells: a high-explosive grenade and an armor-piercing shell.

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 is equipped with an under-mounted grenade launcher, which is 40mm in caliber.

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 a mountain valley near Factory 576, a light shone from the window of a bungalow.

This is the residence of Wang Zhigao, the factory's second-in-command. Jiang Guoyong, another deputy director who is on good terms with him, is also there. On the table are three stir-fried dishes, two cold dishes, and a bottle of Chuzhou Daqu liquor.

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 their deputy director, he couldn't expect him to continue lording it over the factory like he did now. Many of the factory's veteran workers listened to Tan Dexi.

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

Deputy director? That's useless.

With his great contribution in developing two new weapons, Tan Dexi could potentially end his labor at Yangou Farm and return to Factory 576 as chief engineer, provided someone in charge gives 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?"

Jiang Guoyong had always admired Wang Zhigao for his quick thinking and was willing to listen to him.

"You forgot, his assistant, Liu Hongyi, is supposed to be the deputy leader of the research group, but he's actually just a high school student. I've looked into it; Liu Hongyi's father, Liu Chu'an, is currently the director and party branch secretary of Yanggou Farm. He was demoted to Yanggou Farm because he made a mistake. He used to be the deputy leader of the Chuzhou Regional Agricultural Work Leading Group."

"What is Liu Hongyi's background? He's neither a technician at the research institute nor someone from our Factory 576. I heard he was even expelled from Chuzhou No. 1 Middle School for assaulting someone. How could a bastard like him participate in such an important research project and even become the deputy team leader?"

"Let me tell you, I have already reported this situation to Director Kang Jisheng of the region. He will send someone to the factory tomorrow to verify it. Let's cooperate and mobilize some people to write dozens of documents tonight and post them out first thing tomorrow morning to create a buzz."

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

“Even that old bastard Tan Dexi, we’re all being sent back to Yanggou Farm.”

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

"You are the deputy director of the factory, and so am I. This great achievement deserves credit for both 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!"
