Chapter 461: Enough with the top armor
Seeing his actions, the comrades in the Communications Academy were surprised and happy.
The good news is that Mr. Gao never speaks in vain. He will solve it for you right away.
What’s surprising is that even in the face of such a temporary request, he can even come up with two materials for you to choose!
After a while, Comrade Xiao Li came over with two small samples: "Teacher, here are the samples and desensitization instructions you want."
All samples have a desensitization instruction material, which hides what should be hidden, changes what should be modified, and even the names WT-2 and WY-1 have been changed.
Xiao Li put down the materials, then said hello to the comrades from the Institute of Communications and went out.
Gao Zhendong picked up the desensitization instructions and handed them to Mr. Feng: "Mr. Feng, look at which of these two materials is more suitable."
These two materials , in Gao Zhendong's spare time, he asked the former research laboratory, now the technical department of the No. 3 Factory, to develop tungsten copper and tungsten silver materials.
There is only one type of tungsten copper, which is the one with a relatively high copper content.
There is tungsten, which has a high melting point and is also hard.
With copper or silver, it has good conductivity.
Mr. Feng and the comrades at the telephone office looked at these two materials. Although they didn’t know what they were about, the performance parameters were clear.
“This conductivity is 35% IACS, which is about the same as magnesium. That’s enough.”
“What do you mean by that? Didn’t you see that there is another one with 50% IACS?”
%IACS, roughly speaking, is the percentage of the electrical conductivity of international standard annealed copper. The larger the value, the better. 35% is already very high. For example, H90 brass (a copper alloy mainly containing 90% copper and 10% zinc) is 25% IACS.
“The hardness and melting point are very high. With this, general arc ablation and fusion welding are basically no problem.”
“The processing performance is also pretty good, not Like tungsten, it’s too hard to chew, and its electrical performance is not as good as this.”
“This thing alone can save us half the time on the relay. The biggest headache now is this contact. ”
The comrades at the telephone station looked at these two things with joy on their faces. At the same time, they became entangled in the two things with obvious differences in conductive properties.
Because except for the electrical conductivity, other properties are far beyond what is required, and in their opinion, higher electrical conductivity is better.
"Mr. Gao, apart from the visible performance, what is the main difference between these two materials?"
Gao Zhendong smiled and said: "The price, the one with better conductivity is more expensive. Quite a bit, if you calculate a 10,000-door switch, you will need to use several kilograms or even dozens of kilograms of precious metal. If 6007 with poor conductivity can already meet the requirements, I recommend using this one."
Tungsten copper, 6013 is tungsten silver.
As for the specific project implementation, if there are no special requirements, Gao Zhendong’s tendency is to use enough. To the extent that it is sufficient, just leave some margin. If it is too high, it has no meaning anymore. Big.
Especially for things that involve mass production, they have to be replaced due to new demands. You can consider changing them. Until then, the principle is to use enough.
When Gao Zhendong’s previous mentor reviewed projects, he often scolded him, “What the hell, just put up a promotional web page. The hardware should be equipped with a dual-machine hot standby with 32 cores and 128G memory. Hang it up and do nothing. ! It’s better to add safety configurations. If you look at the waste, it will block the way of other projects in the future. They will not even raise the budget.”
The comrades at the telephone office definitely don’t have this idea. , but Gao Zhendong still gave his own suggestions very clearly.
After listening to his suggestion, President Feng of the Institute of Communications nodded: "Mr. Gao makes sense, then let's choose the cheaper one."
A few kilograms or even dozens of kilograms of precious metals , although I don’t know which one it is, but there is no doubt that this dosage is a bit high.
Gao Zhendong did not say anything: "Take these two materials back and give them a try in detail, and then make a decision. In short, my opinion is based on what is sufficient. The performance of the equipment is not a single one." Indicators can determine it.”
Lao Maozi: You are right!
Little devil: It makes so much sense!
Mr. Feng and the others, who had received strong support from Gao Zhendong, rushed directly to Factory 1237 with the newly obtained materials.
The Communications Institute does not directly produce relays itself. The imitation of relays is done in cooperation with the professional No. 1237 Factory of the 12th Machinery Department.
The Postal and Communications Commission and the 12th Machinery Department have a deep relationship.
The comrades of Factory 1237, who were struggling with contact materials, almost jumped three feet high after getting 6007 and 6013.
"General Engineer Feng, where did you find these two materials? They are just like custom-made! Did you ask comrades from the north for help?"
Can you get them so quickly? To come up with such qualified materials, he couldn't think of any other channel except this channel.
Mr. Feng couldn't say anything, so he had to smile and said: "Don't worry about this. Just try to see if this works. The source is stable. As long as it is used, we can get a stable supply. .”
The comrades of Factory 1237 heard the clue and asked: "Is this domestic material?"
If it is not domestic, the words "stable supply" are not very reliable, even if it is made by Lao Maozi. The same goes for , even more unstable. This one can be said: "Well, it's from China. We also found it after a lot of effort across the country."
In fact, it didn't take much effort. I just went to that person's place.
But you have to say this, otherwise it will be easy to frame the scope of the source.
The comrades of Factory 1237 were so happy not just because of the relay.
"Mr. Feng, come on, let's talk here."
Comrades from 1237 invited Mr. Feng aside. What he said next was that the fewer people know about it, the better. Everyone understands. Regulation.
"Mr. Feng, to be honest, these two materials are very useful for an important topic we are doing, especially this 6013, with its mechanical properties, melting point, combined conductivity and corrosion resistance. , is very important to us.”
Tungsten silver material is originally an important contact material in the electronics industry. It is used across many industries. Factory 1237, which specializes in relays and other electronic devices, cannot take its eyes away when it is seen. It's so normal.
As for where it was used and which industry, he didn't say. The reason is probably the same as Mr. Feng's inability to say where he found it.
Mr. Feng understood what he meant: "Old Yao, I understand your mood, and I also understand the excellence of this material. But please understand my difficulties, and you also know the discipline. Even I wouldn’t dare to use it for anything other than our project. However, in our project, you always need to conduct comprehensive testing of the materials. This is what you have to do.”
< br>What he means is very direct. I don’t dare to give you the stuff to use in any other place, not even a gram.
But you can conduct comprehensive testing. For your own projects, first test whether it can really be used. If you find hidden flaws after testing and you can't use it, then don't use anything. explain.
If it comes into use after testing, you can think of another way.
Yao Gong from Factory 1237 also understood what he meant and his approach.
It’s all for the same reason, and no one dares to take a step beyond the limits.
No matter what, it was at least certain that this thing was domestic, and could be mass-produced with a stable source. These two points alone made him overjoyed.
Thinking of this, Yao Gong nodded: "Well, thank you. If it is really available by then, please ask Mr. Feng to show me the way."
It means to show the way, I asked Mr. Feng to tell him how to get permission to inquire about the source of this material.
Mr. Feng smiled and said: "I also hope it can be used. While solving our problems, we can solve your problems together. That would be great."
It's all for the comrades at work, this kind of As long as it doesn't violate the rules, Mr. Feng is still willing to help.
——
Beijing University of Technology, Professor Gao Zhendong, Professor Luo, and Lu Gong from the Guidance and Research Institute got together.
For no other reason than for the terminally sensitive ammunition.
Gao Zhendong is the general manager, Professor Luo is in charge of the war department, and Lu Gong has experience in infrared detection and is responsible for infrared detectors and detection logic.
The person in charge of the parachute is also a comrade in aerodynamics from the Institute of Guidance and Research.
When the project was established, Gao Zhendong formed the team in this way, which was just right.
Lu Gong is very interested in this thing. The improvement work of Thunderbolt-1 modification belongs to him. The core problem has been solved and he can spare his energy.
As a brand-new concept weapon, the terminally sensitive bullet is a hot commodity in the eyes of those who make weapons, purely for the sake of hunting.
Although the Guangdong Research Institute is engaged in missiles, it can still be obtained by Gao Zhendong's strings.
What they are discussing at this time is the basic structure of the terminally sensitive bomb.
"Mr. Gao, I have analyzed that at a distance of 100 meters, air resistance will have a certain impact on penetration depth." Professor Luo has already started working.
Once the self-forged fragment warhead EFP is formed, its shape and initial velocity mainly affect its penetration.
In his previous life, Gao Zhendong read through the papers and saw the testing of tantalum and zirconium energetic EFP. Because the zirconium layer was a little thick, it affected the shape of the EFP. As a result, the penetration depth, structure and copper cover of the charge could not be used. of.
Therefore, many things are not as simple as you take them for granted. If you just take a piece of material and apply it, the result may not be that good.
"What was the result?" Gao Zhendong knew how big the impact was, but he couldn't say it directly. It would be a bit scary, so he had to ask.
“We conducted preliminary analysis and conducted tests using ready-made standard charges and mold covers. The armor-piercing diameter dropped by 60% to 65% at this distance, but it is still sufficient.”
The standard charge he mentioned has now been replaced by Black Mix 60, and the charge diameter, length, filling density, charge cover size and structure, etc. are all clearly defined.
Everyone has long expected that the armor-piercing magnification will decrease. The original armor-piercing magnification of gun-mounted grenades was about 2.0, but now there is still 0.7 to 0.8 left, which is not bad.
This has nothing to do with flying high, it's a matter of aerodynamics.
Gao Zhendong had expected it and had already let it pass. He smiled and said: "Well, it seems that the 110mm caliber warhead can still hit about 80mm, which is enough."
