Chapter 345: I spent the whole afternoon thinking about the recipe

Everyone cheered loudly, this result was really amazing.

Although they did not invent this warhead, they were the ones who manufactured and tested it.

Moreover, regardless of whether it matters or not, we now have such an excellent anti-tank warhead, which is something worth cheering for no matter who looks at it.

The penetration rate of 420mm vertical steel armor is 90%, which means that this warhead can proudly claim that the static armor-piercing capability is 420mm vertically.

Mr. Luo said to Gao Zhendong: "Mr. Gao, congratulations, today is a good start, a good start!"

Gao Zhendong laughed loudly: "Congratulations!"

After laughing, Gao Zhendong looked at the 420 and thought about the original 630. He always felt that something was not right. The current charge still didn't work.

Mr. Luo was very sharp in noticing this problem: "Mr. Gao, you look like you are still not very satisfied?"

Gao Zhendong nodded: "Well, I feel it's still a little short of the mark."

The comrades at the Long Sword Factory looked at him in shock. Are you going to the sky? That's not enough? What else do you want to do?
Gao Zhendong turned around and asked General Luo: "What kind of charge is used in this warhead?"

The main difference between the two lies in the charge in the warhead.

"TNT-XX." Mr. Luo replied. This is a mixed charge made of TNT and RDX.

Gao Zhendong nodded and said nothing more. No matter what, this was something worth being happy about. He recalled the past frantically in his head and said to Mr. Luo, "Let's continue with the next experiment. We need to see in full detail how far we can go."

At General Luo's command, the test of the armor-piercing capability of the inclined armor began.

The test results were very ideal and basically consistent with the vertical armor-piercing capability.

It's stable! If nothing else, this warhead is stable.

After the warhead armor-piercing capability test was completed, it was already noon, and the people from the Changjian Factory and Gao Zhendong went to the cafeteria to eat.

While eating, Gao Zhendong seemed to be thinking about something. It was almost there, almost there. It was not worth wasting four lottery chances for this matter. He could only try hard to search for it in his long-forgotten memories.

Looking at his expression, General Luo thought he was still dissatisfied with the power of the warhead, and comforted him: "General Gao, take a rest and don't think about it. Today's test results are already amazing. The power of the Tihei is already great enough, 420mm. In the past, we couldn't even think about it! General Gao, I want to use this technology to improve our anti-tank missiles. Hahahaha, now I really believe what you said. Although ours is a single-soldier missile, its power is no worse than others' vehicle-mounted heavy bullets!"

Gao Zhendong put aside his thoughts for the time being and said with a smile: "When the test is successful, you can also inform the user representatives and the Defense Work Committee. Although it is not an anti-tank missile, I think they are still interested in the disposable individual rocket launcher."

"Disposable individual rocket launcher? This is a complete product?" Mr. Luo always thought that Gao Zhendong was conducting principle tests on anti-tank missile components, so the fuse, firing mechanism, launch tube and the like were chosen so casually. He didn't expect that this was actually a serious product?

Gao Zhendong smiled: "Of course, otherwise why would I invite you to make such a big fuss?"

Chief Luo was a little worried: "A disposable one, will the higher-ups be willing to spend money on it? Such a large steel tube is not cheap, and it is also much heavier than the old rocket launcher. The infantry can't withstand many rounds."

Gao Zhendong smiled and said, "That launch tube is just for transition. I have already contacted the relevant units and am working on a plastic launch tube."

"Plastic launch tube? Can you bear it?" Mr. Luo found it even more strange. The scene of the old 40 gun firing was truly incredible.

"It's disposable, so the requirements are much lower. And it uses the rocket launch principle, so the tube only plays a directional role. If the requirements are not high, there should be hope."

"Then we can consider reporting it. Just think of it as the second product you and I have developed. Hahaha."

The two of them ate and talked until they finished their meal. Gao Zhendong still couldn't remember the last key point, so he simply let it go. Anyway, the current power was already amazing enough. Not to mention this generation of tanks, even the next generation of tanks would be in a bad way.

Well, apart from my own, it’s really a bit difficult to beat those two.

What we did in the afternoon was the test of the rocket launcher-like bullet, so to speak.

The sample bullets were the same as the pure warhead tests, with no problem with power. Those that could fire basically continued the warhead test data in the morning.

The key issue is that not all of them may explode, especially when Gao Zhendong requires large-angle armor tests and soft target tests above 55 degrees, the probability of a dud ricocheting becomes significantly greater.

The fuse of the old 40 fire still doesn't work, it needs to be replaced!
Although Gao Zhendong has added an anti-slip cap to the design, the inherent defects of the old 40 fire fuse still result in a certain probability of misfiring at large angles and against soft targets.

In fact, this problem is more serious with Old 40 Fire, because that thing doesn’t even have an anti-slip cap.

Mr. Luo and his colleagues felt very embarrassed about this matter. After all, the missile was a success, but it was held back by its own matching fuse.

Moreover, this is not good news for the anti-tank missiles under development. If all of them use this kind of base mechanical fuse, then no one will be much better than the other.

Gao Zhendong looked at the situation and made up his mind: "Mr. Luo, let's use a piezoelectric fuse, which is more reliable than this." Due to structural reasons, it is difficult to arrange a mechanical ignition fuse on the tip of the armor-piercing projectile, so if a mechanical fuse is used, it is generally a base fuze.

As a result, it is impossible to directly utilize impact to ignite, resulting in its reliability being much lower than that of the bullet tip.

The advantage of a piezoelectric fuze is that the tip of the bullet can still be used as the ignition device, and then connected to the detonator in the charge with a wire.

Mr. Luo readily agreed. The fuse issue has always been a difficult problem for the old 40 fire, and it is time to solve it once and for all.

Fortunately, the difficulty of the piezoelectric fuse is not too high. They can organize and solve this problem by themselves, and Gao Zhendong does not need to look up materials.

The range is not bad, because the direct firing distance is 40 meters, which is better than the 100 meters of the old 150 fire.

This direct firing distance means that within this distance, its trajectory can ensure an accurate hit, not that the rocket can only fly 150 meters before falling to the ground.

Although its direct firing distance is slightly less than 89 meters of the 200 barrel, it is definitely enough at this time.

The reason for this is that the burning rate of the propellant is low.

The burning rate of the propellant in the 89 barrel is as high as over 50 mm/s, which is much higher than that of the X12.

Although Gao Zhendong had used a propellant loading method that first appeared in China ten years later, which greatly increased the combustion surface of the propellant and greatly increased the actual burning rate of the propellant, it was still difficult to completely shorten the length of the rocket's active section to within the length of the launch tube.

Simply put, after leaving the launch tube, the propellant continues to burn even after it has lost the directional capability of the launch tube, which has a certain impact on uncontrolled rockets.

However, this is not a big problem, or at least it is more than 50% better than the original stuff, and Gao Zhendong is not going to solve it for the time being.

This cannot be solved by simply adding a little burning rate regulator such as carbon black, the data difference is too big.

It is not the case that the problem can be solved by simply changing from X12 to STD as the Institute of Advanced Technology did. The biggest difference between the two, DNT (dinitrotoluene), has nothing to do with the burning rate.

Thinking of this, Gao Zhendong suddenly remembered.

Holy shit! That's it!

DNT!

Gao Zhendong knew the name of the warhead charge of the Type 89 barrel. He even knew that this charge had a different component from its previous generation to solve the problem of acid corrosion caused by the hydrolysis of the acidic component No. 4.

This medicine No. 4 has a very difficult to pronounce name, and it is probably for this reason that it is referred to as medicine No. 4. As for what No. 1, 2, and 3 are, that is another question.

Gao Zhendong remembered that the composition of the previous generation of propellants was RDX, No. 4 propellant, polyvinyl acetate, and calcium stearate, and he even knew their proportions, but he just couldn't remember what was used to replace No. 89 propellant in the Type 4 warhead.

Polyvinyl acetate is used as an adhesive here, and agent No. 4 is an energetic plasticizer.

Just when he was thinking of STD, he suddenly remembered that the thing that replaced No. 4 medicine was DNT (dinitrotoluene). This magical replacement solved the problem of poor thermal stability of the original charge and easy acid corrosion.

The reason why it is magical is that this problem caused tens of millions of rounds of various ammunition to be scrapped, and this seemingly simple replacement took our respected scientific and technological workers several years.

If we make a simple calculation based on the factory price of 40 yuan per round for the new Type 280 round, the loss of that batch of scrapped ammunition is about 30 billion yuan. That's 30 billion yuan in the s.

We did it, not for anything else, just to skip the previous generation with poor thermal stability and reduce the loss of 30 billion. Even if the power is not improved at all, we have to do it.

Not to mention that after the Ti-XX was replaced with the new propellant, its power increased visibly.

Seeing Gao Zhendong suddenly look ecstatic and muttering something, Mr. Luo became a little worried.

Mr. Gao couldn't be too happy, maybe he was so happy that his brain went wrong, because the results of today's test were so good.

"Mr. Gao, do you want to take a break?"

Gao Zhendong shook his head and excitedly pulled Mr. Luo over.

This is where warheads are produced. We have everything you need!

"Boss Luo, do you have unmixed RDX?"

Mr. Luo finally understood that Gao Zhendong was still thinking about the power. Using pure RDX?
"Boss Gao, pure RDX won't work. It's too sensitive."

Pure black metal is completely useless. It can cause combustion and explosion when exposed to open flames, high temperatures, vibrations, impacts, or friction. What's more, it's also poisonous.
