In 1978, I was admitted to Harbin Institute of Technology

Chapter 163 The cost is shockingly low. If one shot is not enough, just add a few more.
"Principal, whether it succeeds or not, we have to make the product first. For our school, if we can get the technical data of individual rocket launchers from other units, it shouldn't be difficult to make a disposable individual rocket launcher, right?"

Xie Wei didn't know whether the school had any technical information.

Disposable individual rocket launchers, such as the Type 70 with double launch tubes, have low technical performance; the FHJ84 62mm individual rocket launcher mainly launches smoke bombs and incendiary bombs.

The one that the troops are really equipped with is the PF89, which not only has anti-tank bombs, but also different types of bombs such as fuel-air explosive bombs, assault bombs, and anti-personnel bombs.

"I'm not a technician, how do I know if it's difficult or not?"

Li Rui looked at Xie Wei unhappily.

Xie Wei really made him think.

Who doesn’t want every soldier in their country to have a gun?

Back then on the peninsula, we suffered a lot from the heavy firepower of the 17-nation coalition forces.

"Then what are you worried about?"

Xie Wei looked at the old man unhappily.

“Where will the money come from?”

"What does this have to do with me?"

Xie Wei didn't hesitate at all and directly retorted to the old man, "The school's projects, where the funds will come from is something the school leaders need to consider."

Seeing Li Rui's lips move, Xie Wei knew what he wanted to say and quickly added, "Even if you want to run the school-enterprise office, don't ask me. The person in charge of the school-enterprise office is Wang Zheng, you assign tasks to him!"

After saying that, without waiting for Li Rui's reaction, Xie Wei turned and left.

His abnormal behavior stunned the experienced Principal Li. By the time he reacted, Xie Wei had already walked a long way away.

"This kid is getting smarter and smarter! I haven't even said this yet!"

Principal Li felt extremely upset as Xie Wei blocked his words before he could even utter a word.

He wanted to call Xie Wei, but when he thought of Xie Wei's attitude, and also knew that many of the school's self-funded projects were pushed to the school-enterprise office, he could only smile bitterly and shook his head, "It seems that we have to think of other ways."

"What other options are there? The school had previously misappropriated funds, and the hole was finally filled after the ministry gave it 1200 million, but this year..."

Liu Debao looked at Li Rui and rubbed his forehead, which had few hairs left.

Wide headache.

He didn't want to get involved in this matter, but he supported Tang Daoxian's sniper grenade project.

It is not known whether Zhai Xinguo proposed the disposable rocket launcher project based on Xie Wei's reminder or by seeing the operation of other projects. He did not say that it was a new project, but rather used test data to tell them that the current technical reserves were insufficient and the experience was not rich enough, and that they needed to accumulate experience through other sub-projects...

"What's the big deal! As long as the projects can continue to operate and achieve results, we can ask the relevant units for funding!"

Principal Li does not think that misappropriation of funds is a problem.

The problem is that we don’t have enough results to ask our superiors for funding.

"Did you find out about the new rocket fuel?"

"Don't mention it! The ministry only gave 40 yuan, and they said the school just did some theoretical research and didn't spend any money..."

Speaking of this, Principal Li became angry.

The new fuel developed by the school has significantly improved the performance of launch vehicles and liquid intercontinental missiles, but the ministry simply refused to buy it, saying that the main research was being carried out by other units.

Tang Long and two teachers from the school worked in other units.

"We must never do this again! Even if we have to tighten our belts, we must first get some results from the project at school before asking the relevant units for funding..."

"..."

Liu Debao simply ignored this.

Tighten your belt?
My waist is about to break now, and I am completely robbing Peter to pay Paul, and my funds are still tight.

For a moment, both of them were silent.

······
"Squad leader, can you help me take a look at this design?"

As soon as the get out of class was over in the afternoon and Xie Wei just walked out of the classroom, Tang Daoxian jumped behind him and handed Xie Wei a few pages of paper with the school's letterhead printed on it.

the voice very low.

While he was speaking, he also looked around to see if there was anyone nearby who could hear or see what he was holding.

"Old Tang, you have a mentor!"

Xie Wei did not take the plan that Tang Daoxian handed to him, and looked at him helplessly.

He didn't follow Tang Daoxian out. When his classmates in the classroom saw him and Tang Daoxian at the door, they left directly through the back door, which made Xie Wei even more helpless.

If I had known this earlier, I would have ignored Tang Daoxian.

Damn it, it's like a dog-skin plaster that's sticking to me.

It is still summer vacation now. Perhaps because of the special nature of the experimental class, or in order to make up for the foundation of the experimental class, the experimental class did not have a holiday during the winter vacation, so it also did not have a holiday during the summer vacation.

There are still three large classes every day, and after class in the afternoon, students participate in "practical training".

Yes, the school changed its name.

For students in the experimental class, participating in the project is “practical training”!
Everyone wishes there were 48 hours in a day, and no one has any objections.

"Professor Zhai and I discussed this together and asked me to show it to you. I hope to hear your suggestions."

Tang Daoxian grinned.

It turns out that Zhai Xinguo is not a good person!
He betrayed me to the principal, and I haven't even settled the score with him yet, but now he has ordered Tang Daoxian to exploit my brain cells.

"Squad leader, the plan was proposed by you. In the past few days, Master Zhai and I have been discussing how to reduce costs and increase power as much as possible..."

Only then did Xie Wei realize that Tang Daoxian's eyes were bloodshot and he looked very haggard.

Hearing that Zhai Xinguo also felt the same way, he couldn't help but sigh inwardly.

People these days are always so impatient when doing things.

"If you want to reduce costs, don't use thin-walled aluminum alloy tubes for the launch tube; don't use the sight of the Type 69 rocket launcher, which can be used repeatedly. Your proposal is just using a previous mature design, which actually only reduces the R&D cost, but not the production and use costs."

After reading the plan, Xie Wei shook his head.

The entire plan does not involve much innovation or improvement. The launch tube has only been improved, with the rocket installed inside the launch tube. Unlike the Type 69 rocket launcher, the launch tube no longer has to bear the huge pressure during launch.

Even if this design is successful, the army will not want it.

The current PLA is so poor!
"What to do?"

"..."

Xie Wei was speechless and wanted to ask Tang Daoxian, is it you who wants to do the trick or me?

Why do you ask me everything?

But thinking that every soldier would have a rocket launcher in combat, he still told the other side the technical features of the PF89 rocket launcher, "From the rocket inside to the launch tube outside, the simpler the process can be, the simpler the process can be. To save costs, the process must be simplified, and the materials must meet the most basic needs..."

Tang Daoxian was confused.

"So, whether it's the launch tube or the warhead, we try to use a one-time molding process. As for the materials, it's easier to say. The launch tube is thrown away after it's used. You can't expect the troops to recycle the scrapped launch tubes after they fire rockets during combat, right? Even the worst aluminum alloy costs more than 10,000 yuan per ton!"

Xie Wei made a small smile.

Tang Daoxian couldn't laugh at all.

"So, the launch tube can be made of fiberglass or engineering plastics. We have all the materials for this. The most expensive part of the rocket is the engine. The three major parts of the engine, the connecting screw, the combustion chamber, and the nozzle with the tail seat, are directly made of aluminum alloy hot extrusion. The warhead can be stamped or pressed..."

In order to avoid Tang Daoxian's trouble, he directly told him the technical features of the PF89 rocket launcher. Can't produce it?
nonexistent.

These technologies and materials are now mature in China, but in the previous era of planned production, as long as they can be produced, cost is not a problem.

The PF89 rocket launcher was developed when the army was at its poorest, when it needed to maximize combat effectiveness at the lowest cost.

Many of the design proposals are extremely bold.

At least, in the eyes of military designers these days, it is not reliable enough.

"Sergeant, this is for military use!"

Military products must be reliable.

If the durability and endurance of the equipment were not considered during the design, how could the comrades in the army accept it?

Tang Daoxian's eyes suddenly widened and he looked at Xie Wei in astonishment.

He wanted to remind Xie Wei and let him think about what he said!
"Yes! For military products, as long as the launch tube can fire the rocket without blowing up the user, it's fine. As for rockets, it's even easier to say, as long as they can reach the designed power within the range..."

"..."

Tang Daoxian was dumbfounded.

He felt that he could no longer listen to Xie Wei.

If I continue like this and really succeed in designing it, I'm afraid I won't be able to wait until the troops try it out, and I might even get killed when I test it myself.

"Anyway, this is my suggestion. It's up to you whether you listen to it or not. Old Tang, although I am the squad leader, I am not omnipotent, and I have no interest in designing rocket launchers. Please don't come to me again."

Xie Wei didn't care what Tang Daoxian thought.

She warned him not to come to see her again before leaving.

The CNC system of the Mechanical and Electrical Engineering Department has reached the debugging stage, and the PLC programmable controller has also entered the sample trial production stage. He is very busy during this period.

After receiving Xie Wei's advice, Tang Daoxian's face was filled with sorrow and he did not dare to go back to find Zhai Xinguo at all.

He was afraid that his usually strict tutor would think he was stupid.

I ran to the study room, listed out what Xie Wei said, and then compared it with the previous plan. No matter how I looked at it, I felt that Xie Wei's proposal was not reliable at all.

He couldn't sleep all night.

The next morning, I had to muster up my energy and go to Professor Zhai to report.

"What? Did you miss another sleepless night?"

Seeing that Tang Daoxian's eyes were red and his whole body was unsteady when he walked, he couldn't help but frown.

"Teacher, I..."

The mentor, who was already strict, now had a gloomy face, and Tang Daoxian didn't know how to start talking.

"Xie Wei didn't give any advice?"

Zhai Xinguo asked.

"It's not...it's just..."

Being stared at closely by his tutor, Tang Daoxian was so panicked that he even stuttered when speaking.

He was worried that if he displeased his tutor, Zhai Xinguo would eventually stop teaching him.

The school couldn't find any other teacher who could teach him about gun design.

In desperation, he could only hand over the plan that Xie Wei had proposed yesterday to Zhai Xinguo.

"Bang~"

Before he even finished reading it, Zhai Xinguo flew into a rage.

He slammed the papers written by Tang Daoxian containing Xie Wei's proposals on the desk.

Tang Daoxian, who was already extremely nervous, was frightened by the sound of slapping the table and began to tremble.

"What nonsense! If it is really designed like this, such a weapon is a waste of money! Don't even mention whether the comrades in the army are confident. If it were you, would you dare to test-fire it? Have you forgotten what I told you on the first day?"

"As a weapon designer, you must first ensure that the weapons you design are safe to use! This is the responsibility of a weapon designer!"

Stared at by Zhai Xinguo's angry gaze, Tang Daoxian answered tremblingly.

"After designing such a plan, do you dare to test-fire it?"

Zhai Xinguo's voice was almost squeezed out from between his teeth.

"Teacher, this is the class monitor's suggestion. Yesterday I looked up some information and did some simple calculations. According to this plan, the safety performance should be guaranteed..."

"I don't want should! I want sure!"

Zhai Xinguo's face was twisted with anger.

At this moment, he wished he could slap the only student in front of him to death.

Seeing Zhai Xinguo's reaction, Tang Daoxian was not as flustered as before.

He knew very well that if his explanation was not reasonable, Professor Zhai would not teach him again.

Taking a few deep breaths to calm himself down, Tang Daoxian lowered his head and said, not daring to look at Zhai Xinguo's angry eyes:
"Teacher, the country's policies have been adjusted. Everything has been compromised for economic infrastructure construction, and the military has cut funding... I roughly calculated that if this design is followed, the cost of each rocket, including the launch tube, will not exceed 220 yuan."

"220 yuan?"

Zhai Xinguo was stunned.

This is a rocket!

The cheapest 40-round rifle costs 380 yuan per round.

"Yes. Since it's disposable, the scope doesn't need to be used repeatedly. And as long as the power is strong enough, at a distance of several hundred meters, the accuracy doesn't need to be too high... If you miss with one shot, just fire a few more..."

The cost is cheap anyway.

According to Xie Wei, when necessary, each member of the infantry squad will be given a round and will throw it away after firing.

In this case, an infantry squad can carry 10 rocket launchers, all attacking one target, which is comparable to a salvo from an artillery platoon.

Zhai Xinguo remained silent.

The military budget cuts have been felt not only by the troops but also by the military-industrial complex.

If new weapons cannot be made more cost-effective, the troops will certainly not equip them on a large scale unless they are strategic or represent a significant improvement in the overall national defense capability.

Which weapons designer doesn’t want the army to equip itself with weapons designed by him on a large scale?
"Teacher, if the production scale is large, the cost will be further reduced..."

"What you said is only theoretical. As for the details, let's refine the plan first. Let's get this done during this period of time."

Zhai Xinguo compromised.

The plan may not work, but you can give it a try.

Theoretical design is just dead brain cells. Once the theoretical demonstration proves that it is feasible, we will continue the design and then manufacture sample bullets for testing.

Give it a try, there's no harm in that.

If it really doesn't work, just treat it as doing homework with your only student.

So, the master and apprentice began to design this disposable rocket launcher with various materials and craftsmanship that were almost close to the minimum standards for use.
