In 1978, I was admitted to Harbin Institute of Technology

Chapter 156 Range is truth, caliber is justice
"Aside from the explosive part of the warhead, the 40mm ammunition can also hold a lot of propellant. The 1000-meter precision range can increase the effectiveness of this design in combat and gain the favor of the troops."

"Just think about it, if you can accurately fire a 1000mm grenade into the entrance of an enemy bunker at a distance of 40 meters, what will the troops' reaction be?"

Xie Wei became more and more excited as he spoke.

"..."

Tang Daoxian was completely dumbfounded.

A 20mm machine gun cannot accurately hit the target at a range of 1000 meters.

His design combines the power of an artillery shell with the accuracy of a sniper rifle. Although it is not as powerful as a bazooka, it has a much longer range, is more accurate, and is easier to carry.

However, Xie Wei told him that the caliber was too small, and even if the accuracy was improved, it would not be favored by the troops because of its lack of power.

Xie Wei’s proposal was even more difficult to accept.

The 40mm caliber, even if the range is longer than the 40mm round, its power cannot be compared with the 40mm round.

40mm can not only be used for fortifications, but also for countering armored vehicles.

"Squad leader, a 40mm grenade launcher has to have an effective range of 1000 meters and the same accuracy as a gun, so it's not light. Also, the ammunition is heavy and inconvenient to carry... The troops have 40mm or even 60mm grenade launchers, and they don't count towards the establishment, so everyone can have one in wartime."

Tang Daoxian reminded Xie Wei.

What I want to make is a single-soldier support firepower with a longer range and higher hit rate than a single-soldier rocket launcher.

According to the design proposed by Xie Wei, it cannot be compared with the more powerful 40 fire and 60 fire.

"20mm machine guns are usually mounted on vehicles or warships. The 14.5mm anti-tank guns were eliminated during World War II because they were too heavy and inconvenient to carry. In addition, the recoil was too strong, and almost one shot would cripple a soldier. I'm afraid that ordinary soldiers cannot withstand the recoil of 40mm..."

Tang Daoxian believed that he understood this aspect better than the squad leader.

The monitor's proposal is completely an outsider's opinion.

"No!"

Xie Wei shook his head and looked at Tang Daoxian with a firm expression.

He knew that Tang Daoxian had fallen into a misconception.

The 14.5mm anti-tank gun is almost the limit of individual weapons. This is because when firing such a large-caliber ammunition, in order to make the huge warhead obtain a very high initial velocity, in order to increase the range and power, more propellant must be installed.

The huge impact force generated by the propellant instantly creates a recoil force that can directly shatter the shoulder blade of the soldier who fired the shot.

This is a misconception.

"Have you ever considered reducing the instantaneous impact force by reducing the amount of propellant when the huge recoil force generated by the propellant is too much for the soldiers to bear..."

"That's impossible! If the amount of propellant is reduced, the initial velocity will be insufficient and the range and power will not be sufficient."

Tang Daoxian interrupted Xie Wei before he could finish.

Xie Wei's words broke his defense.

Although the monitor is very capable, it seems that he does not know nothing.

If you really understood, you wouldn’t be able to say these words.

"Old Tang, don't get excited yet."

Xie Wei was a little speechless. He knew that technical people always believed they were right until they were convinced. If he hadn't known about the LG-5 sniper grenade launcher equipped by the PLA, he would have thought that such a plan was too crazy.

After the LG-5 grenade launcher, the grenade launchers equipped by the troops began to develop in the direction of high intelligence.

"The dose is reduced when the launcher is fired, but what if the grenade itself carries some propellant? Like a rocket..."

"what?"

Xie Wei's suggestion immediately made Tang Daoxian's eyes widen, and his mouth was big enough to fit a fist.

The grenade loads its own propellant?
Is this still a grenade launcher?
Guns and cannons don’t have such a design.

"Think about it. The tail doesn't need an engine, but it can provide some power after it leaves the barrel. It doesn't need to be too fast, it just needs to steadily push the warhead to the target within the range to stabilize the trajectory..."

Xie Wei was just making a suggestion.

It doesn’t matter whether Tang Daoxian can do it or not.

"Of course, in the early stages, we can actually ignore such a long range and improve the accuracy and power."

Seeing the confusion in Tang Daoxian's eyes, Xie Wei knew that his proposal had a great impact on the other party and it would take time to digest.

He let Tang Daoxian leave directly, and he took the 20mm sniper grenade design plan provided by Tang Daoxian to find his class instructor Luo Yang.

"Weapon design major? The school hasn't had it for many years."

When Luo Yang heard Xie Wei asking about his major, he looked at him in confusion.

Harbin Institute of Technology used to have a weapons design major, and could even design rocket launchers and heavy artillery, not to mention ordinary firearms.

However, for those who work in the military industry, after studying related majors, most people choose to design heavy artillery rather than firearms.

This may also be because since the beginning of the century of humiliation, the entire country and nation have suffered too much from artillery fire.

“It doesn’t matter if there is no major, as long as there is a teacher in this field.”

Xie Wei knew the situation of Harbin Institute of Technology.

The college entrance examination has just been resumed, and this year is only the third year.

The school originally had only 10 majors for enrollment, and with the three new majors in aerospace and two additional core majors added this year, there are only 15 majors for enrollment in total.

Firearms design falls into the category of engineering.

There are currently almost no specialized enrollment majors in the country.

A lot can be seen from the resumes of some domestic firearms design masters.

"how?"

Luo Yang looked at Xie Wei in confusion, "Are you interested in gun design again?"

"No. Tang Daoxian, are you familiar with him?"

"He? Isn't he in the computer project team? He usually doesn't say a word and has almost no presence."

Luo Yang and Xie Wei have highly consistent views on Tang Daoxian.

Even if I look at it every day, I won’t think of it if no one mentions it.

The sense of presence is very low.

“This is his design.”

Xie Wei handed Tang Daoxian's plan to Luo Yang. The reason why he did not let Tang Daoxian come to Luo Yang in person was that Xie Wei knew very well that a student like Tang Daoxian would find it difficult to attract the attention of his superiors anywhere.

If the 40mm sniper grenade launcher can be developed in advance, it will provide a new business growth point in the upcoming Two Camel War.

Internationally, there are not many individual grenade launchers with a range of over 100 meters.

Not to mention the accuracy.

The 20mm caliber is not large, and the design is somewhat feasible, but for combat troops, it is completely useless.

From all aspects, Luo Yang would not be too supportive.

"he?"

Luo Yang took the design plan handed over by Xie Wei with surprise on his face.

When he saw the 20mm caliber "big gun", he instinctively thought it was nonsense. The fact that Xie Wei came to him alone meant that the plan should have some potential.

He immediately looked through the design plan patiently.

"Xie Wei. This is a good idea. We can launch grenades at a distance of 400 meters to accurately destroy the enemy's fortifications, but the power of 20mm ammunition is too small. At this distance, the 60 mortar is sufficient..."

Luo Yang didn't know what Xie Wei valued about this plan.

If he didn't know the situation of the whole class, he would really suspect that Xie Wei came to him because of his personal relationship with Tang Daoxian.

"Can the mortar accurately fire shells into the firing port of the bunker?" "Of course not."

"Can mortars be distributed to infantry squads?"

"The minimum company-level supporting firepower. The infantry squad's supporting firepower is the rocket launcher."

"The range of the rocket launcher is not that far. The power of a single 20mm shell is not very strong. We need to rely on quantity..."

Luo Yang understood what Xie Wei meant.

The plan in hand is really useless.

The caliber is still too small.

When facing individual enemy forces, a gun is enough; for clustered targets, the killing radius of a 20mm artillery shell is too small.

"Xie Wei, 20mm machine guns are generally used for close-range air defense on warships or close-range combat on fighter planes... The army, even armored vehicles, rarely choose 20mm machine guns as weapons."

Luo Yang reminded Xie Wei.

Even though he is the school's principal, he has had a military career and is familiar with the basic equipment of the troops.

The position of the 20mm machine gun is indeed very embarrassing.

"What if the caliber is increased to 40 mm, the range is increased to 1000 meters, and the shells can be accurately delivered to the firing port of the bunker within a range of 1000 meters?"

"impossible!"

Without even thinking about it, Luo Yang denied what Xie Wei said without hesitation.

Just kidding!
If it can really achieve the range and accuracy that Xie Wei described, wouldn't it become a sniper gun?

"Let alone other things, the recoil alone is something that the human body cannot bear! Xie Wei, you should just focus on the work at hand."

Seeing Xie Wei looking at him with a smile and not refutating, Luo Yang felt uneasy.

I kept thinking whether there was anything I had not considered.

"Class instructor, the purpose of the experimental class is to allow students to grow quickly according to their interests. Although the possibility of achieving this parameter is relatively small at present, I think we can let Tang Daoxian develop in this direction. This is his interest direction... If we really make it, the demand for it in the army is still very high."

"How?"

Luo Yang was stunned.

He didn't expect that even though he had explained it so clearly, Xie Wei still insisted.

"Find an experienced teacher in gun design to guide him and let him study this. The army's weapons and equipment have long been outdated."

Xie Wei's eyes were firm. "If there is no professional teacher, the school will give him some funds and let the relevant professional teachers guide him, and wait for him to figure it out. If it succeeds, the army's squadron-level support firepower will have one more option; if it fails, the school will not lose anything. This is a single-soldier weapon, easy to carry, and can be used for support at any time, without waiting for the support of the artillery squad."

LG-5 sniper grenade is not equipped by many PLA troops.

But the export market is huge.

The real reason why this thing produces huge power is when it is installed on a robot dog. With the robot dog's huge ammunition capacity and powerful power, it directly becomes a walking high-precision individual sniper turret!
It is still a long way to go before we can make a robot dog.

You can make the robot dog’s weapons first.

No problem.

"I can't make the decision on this matter."

Seeing Xie Wei's firm attitude, Luo Yang felt helpless and directly passed the ball to the school leaders: "Why don't you talk to Principal Li or Principal Liu?"

Seeing that Luo Yang didn't want to interfere in this matter, Xie Wei despised him in his heart, but there was no change on the surface.

"Ranger is truth, caliber is justice? Well said! Well said!"

After hearing what Xie Wei said, Liu Debao repeated it and clapped his hands.

The larger the caliber, the greater the power.

The greater the power, the more just it is.

"Sniper cannon? That's great! Do you have a complete design plan?"

In front of the powerful Principal Li, Liu Debao's presence is also very low, at least to Xie Wei and others.

But after all, he is the second in command of the school besides Li Rui.

Principal Li is not in school now, and Xie Wei has no intention of going to old man Li Rui for such a small project.

"Yes, it's just a preliminary plan. After I talked to him, he went back to prepare to modify the design. The caliber was increased to 40 mm, and the range was increased to 1000 mm..."

Xie Wei also knew Secretary Liu's personality very well.

There was news a few years ago that Li Rui would be transferred to the department and Liu Debao would take over the position of principal, but somehow an accident happened.

Normally, Liu Debao is more involved in various projects than Li Rui.

Even though every project was decided by Li Rui.

"so?"

Liu Debao couldn't believe the data Xie Wei presented. He felt Xie Wei was just bragging. "How much funding do you need?"

Whenever there was a project, Xie Wei would look for Li Rui, and Liu Debao knew about it.

If Li Rui wasn't in school right now, the other party probably wouldn't have looked for him either.

"About 5 yuan for the initial stage. But for now, funding is not a problem."

The design plan provided by Tang Daoxian has not been verified.

Now Xie Wei asked him to increase the caliber to 40 mm, increase the effective range to 800~1000 meters, and even let the ammunition carry a certain amount of propellant itself. The entire design needs to start over and needs to be demonstrated.

Due to staff shortage, theoretical design and demonstration will take a long time, and no funds are needed in the early stages.

"That?"

Liu Debao was confused.

Xie Wei went to Li Rui to ask for money, but now he comes to me to talk about the project and doesn’t want money anymore?

"Teacher! This plan was designed by a student in the experimental class. He has a certain foundation in this area, but he is not professional. The information related to gun design in the school library is also more than 20 years old..."

"Is that so?"

After listening to this, Liu Debao weighed the pros and cons quickly and made a decision, "You go back first, I'll think about it and then I'll find you, how about that?"

Seeing that Liu Debao did not directly refuse, Xie Wei naturally did not waste Secretary Liu's time here.

Say goodbye and leave directly.

As long as there is no direct refusal, it basically means that Liu Debao agrees.

"What's this kid up to?"

After Xie Wei left, Liu Debao pondered for a long time and couldn't understand why Xie Wei suddenly came to him.

After thinking about it, I felt that there was only one possibility: this guy asked for too much money from Li Rui, so Principal Li didn't want to see him at all. He couldn't get support from Principal Li, so he came to me.

Why is this a crazy 40mm sniper gun project?
Test!

He was testing whether he, the second-in-command of the school, could support his project.

The more Secretary Liu thought about it, the more he felt that this was Xie Wei's purpose.

Must support!

Even if Principal Li objects.

"Xiao Yao, go and find Zhai Xinguo to come with me."

After making the decision, Liu Debao directly asked his secretary to find someone according to Xie Wei's requirements.
