Chapter 345: I thought about the recipe all afternoon
Everyone burst into laughter, the result was really amazing.
Although they did not create this warhead, the manufacturing and testing were done by them.
Moreover, regardless of whether it is related or not, we have such an excellent anti-tank warhead anyway. No matter who looks at it, this is something worthy of cheering.
The penetration rate of 420mm vertical steel armor is 90%, which means that this warhead can proudly claim that its static armor penetration 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: "Same joy!"
< br>After laughing, Gao Zhendong looked at the 420 and then thought about the original 630. He always felt a little bit uncomfortable in his heart. The current charge still didn't work.
Mr. Luo discovered this problem very keenly: "Mr. Gao, it seems that you are still not satisfied?"
Gao Zhendong nodded: "Well, I still feel Almost meaningless.”
The comrades in the Changjian Factory all looked at him in shock. Are you going to go to heaven? Isn't this enough? What else do you want to do?
Gao Zhendong turned to ask Mr. Luo: "Which type of charge is used in this warhead?"
The main difference between the two lies in the charge of the warhead.
“TNT-XX.” Mr. Luo replied, this is a mixed charge made of TNT and RDX.
Gao Zhendong nodded and said no more. In any case, this was already something to be happy about. While he was recalling crazily in his head, he said to Mr. Luo: "Continue with the subsequent experiments. Well, let’s take a complete look at how far it can go.”
Mr. Luo gave an order, and the test of the armor-breaking ability of the inclined armor began.
The test results are very satisfactory and are basically consistent with the vertical armor-piercing ability.
Stable! If nothing else, this warhead is stable.
After the warhead's armor-breaking capability test was completed, it was already noon. The people from the Changjian Factory and Gao Zhendong went to the canteen to eat.
While eating, Gao Zhendong was thoughtful, just a little bit close, just a little bit close. It’s not worth spending 4 lottery opportunities on this matter. I can only search hard in the memory that has been dusted for a long time. .
Mr. Luo looked at him, thinking that he was still dissatisfied with the power of the warhead, and comforted him: "Mr. Gao, take a rest, don't think about it. The results of today's test are already amazing. Tihei's power has already been It's big enough, 420mm. I couldn't even think about it before! Mr. Gao, I want to use this technology to improve our anti-tank missiles. Hahaha, now I really believe what you said, even though we are engaged in a It’s an individual soldier bomb, but it’s no worse than other people’s vehicle-mounted heavy-duty bombs!”
Gao Zhendong temporarily put down his thoughts and said with a smile: “When the test is successful, you can also report it to the user representatives and the National Defense Work Committee! Bian informed that although it is not an anti-tank missile, I think they are still interested in the disposable individual rocket launcher. "
"Is this a complete product?" Mr. Luo always thought. Gao Zhendong was conducting principle testing of anti-tank missile components, so the fuze, firing mechanism, launch tube, etc. were chosen so casually. Who would have expected that this would actually be a serious product?
Gao Zhendong smiled: "Absolutely, otherwise why would I ask you to engage in such a big battle?"
Mr. Luo was a little worried: "It's a one-time thing, will the boss be willing to do it? So? The big steel pipe is not cheap, and it is heavier than the old rocket launcher. The infantry cannot withstand a few rounds.”
Gao Zhendong smiled and said: "That launcher is for transitional use. I have contacted the relevant units and are working on a plastic launcher."
"Plastic launcher? Can you stand it?" Mr. Luo felt even more curious. Okay, the battle that the old 40 fire launched was incredible.
“The requirements will be much lower for one-time use, and it adopts the principle of rocket launch. The tube only plays a directional role. If the requirements are not high, there should be hope.”
“Then you can consider reporting it. Just think of it as the second product you brought us to develop, hahaha.”
The two of them just chatted while eating. Until they finished eating, Gao Zhendong still didn’t think of the last key point. Come on, let's put it down for now. Anyway, the power now is already amazing enough. Not to mention this generation of tanks, it is enough to give them a face if they encounter the next generation of tanks.
Well, except for my own family, if you want to penetrate those two, it's really not fun.
What we did in the afternoon was the test of the rocket launcher prototype, so to speak.
The sample bomb is the same as the pure warhead test, and its power is no problem. As long as it can be fired, it basically continues the test data of the warhead in the morning.
The key problem is that it may not always succeed. Especially when Gao Zhendong requires armor tests and soft target tests at a large inclination angle of more than 55 degrees, the chance of a dumb bomb ricocheting is obviously higher.
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 problems caused by the old 40 fire fuse in the womb still lead to a certain probability of not firing at large inclination angles and soft targets.
Actually, this problem is more serious with the old 40, which doesn’t even have an anti-slip cap.
Mr. Luo and the others were very embarrassed about this matter. After all, the bomb was successful, but it was held back by its own matching fuse.
And this is not good news for the anti-tank missiles under development. If they all use this kind of mechanical fuse at the bottom of the missile, no one will be any better than the other.
Gao Zhendong looked at this situation and made up his mind: "Mr. Luo, let's make a piezoelectric fuse. It 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 bullet. Yes, so for mechanical fuzes, they are generally bottom fuzes.
As a result, it cannot directly use the impact to fire, resulting in its reliability being much worse than that on the bullet tip.
The advantage of the piezoelectric fuze is that the tip of the bullet can still be used as the ignition device, and then a wire can be connected to the detonator in the charge.
Mr. Luo readily agreed. The fuze issue was originally a long-standing problem for Lao 40 Fire, and it was time to completely resolve it.
Fortunately, the difficulty of the piezoelectric fuze is quite good, not too high. They can organize and solve this problem by themselves, and there is no need for Gao Zhendong to dig up the materials.
The range is not bad, because the direct range is 150 meters which is better than the 100 meters of the old 40 fire.
This direct shooting distance means that within this distance, its ballistic trajectory can ensure a precise hit, not that the rocket can only fly 150 meters before falling to the ground.
Although the direct range of the 89 tube is more than 200 meters, it is slightly closer, but at this time, it is definitely enough.
The reason is that the burning rate of the propellant is low.
The propellant burning rate of the 89 cylinder is as high as more than 50 mm/s, which is much higher than that of the X12.
Although Gao Zhendong has used a propellant filling method that first appeared in China ten years later, which has greatly improved the burning surface of the propellant and greatly increased the actual burning rate of the propellant, it is still difficult to reduce the length of the active section of the rocket. Completely shortened to within the length of the launch tube.
To put it simply, after leaving the launch tube, the propellant is still burning after breaking away from the directional ability of the launch tube. This has a certain impact on uncontrolled rockets.
But this is not a big problem, or at least it has improved by more than 50% compared to the original thing. Gao Zhendong is not ready to solve it yet.
This is not just a matter of adding a little burning rate regulator such as carbon black. The data difference is too big.
The problem is not solved by changing from X12 to STD like the Guangdong Research Institute. The biggest difference between the two is DNT (dinitrotoluene) which has nothing to do with the burning speed.
Thinking of this, Gao Zhendong suddenly remembered.
Fuck me! That's it!
DNT!
Gao Zhendong knew the name of the 89-cylinder warhead charge. He even knew that this charge had a different component from its previous generation to solve the problem of the acidic No. 4 charge. Hydrolysis leads to acid corrosion problems.
This No. 4 drug has a very hard-to-pronounce name. It is probably for this reason that it is referred to as No. 4 drug. As for what No. 1, 2, and 3 are, that is another question.
Gao Zhendong remembered that the previous generation of explosives was composed of RDX, No. 4, polyvinyl acetate, and calcium stearate, and even knew their proportions, but he just didn’t remember what the 89 barrel warhead charge was replaced with. I took medicine No. 4.
Polyvinyl acetate is used as an adhesive, and No. 4 drug is an energy-containing plasticizer.
Just when he was thinking about STD, he suddenly remembered that the thing that replaced Drug No. 4 was DNT (dinitrotoluene). This magical substitution solved the problem of the original drug. Poor thermal stability can easily lead to acid corrosion problems.
The reason why it is said to be magical is that this problem has led to the scrapping of tens of millions of rounds of various ammunition, and this seemingly simple replacement has taken our respected scientific and technological workers several years.
Based on the simple calculation based on the ex-factory price of the new 40-fire 280 yuan per round, the loss of that batch of scrapped ammunition is about 3 billion, which is 3 billion in the past seven years.
I did it, for no other reason than to skip the previous generation with poor thermal stability and reduce the loss of 3 billion. Even if the power cannot be improved at all, I still have to do it.
Not to mention that after the Tihei-XX was replaced with a new charge, its power increased visibly to the naked eye.
Seeing Gao Zhendong suddenly look ecstatic and muttering words, Mr. Luo was a little worried.
Mr. Gao shouldn't be too happy, maybe so happy that his head is broken, because the results of today's test are really great.
"Mr. Gao, do you want to take a break?"
Gao Zhendong shook his head and pulled Mr. Luo over excitedly.
This is the place where warheads are produced, everything you need is available!
"Mr. Luo, do you have unmixed black cord gold men?"
Mr. Luo then realized that Gao Zhendong was still thinking about power, using pure black cord gold gold?
“Mr. Gao, pure RDX won’t work, it’s too sensitive.”
Pure black lead metal cannot be used at all. It can cause combustion and explosion when exposed to open flames, high temperatures, vibrations, impacts, and friction, and it is also poisonous.
