Chapter 263 Reality is far more magical than fiction
“Hey, at that time, I thought that asphalt coke and sulfur-modified asphalt binder would be a match made in heaven. Focus is mainly on coke. "
In fact, this is not a mockery of the Carbon Research Institute. In the current lack of systematic theoretical support and complete testing and testing methods, this simple starting point is not a bad thing. .
However, the Carbon Research Institute cannot laugh at him. Old Duan can still laugh at him. Who calls him an acquaintance? This is called killing acquaintance.
However, the familiar old Duan did not mind at all, but looked happy: "Director Gao, say hello to me and let me use your confidential channel."
It would take several days for me to bring the news back, and I was wasted on the road. I just made a phone call and sent the news back first, and started working on it in the courtyard first.
Mr. Cai looked confused. Why don’t you ask a few more questions about the principle and reason?
But it was obvious that Duan Gong had no such idea at all. After Gao Zhendong called the confidential room, he happily followed the technician Gao Zhendong invited to lead the way.
Mr. Cai was a little dumbfounded as he watched Duan Gong go out. Gao Zhendong turned to him with a smile: "Mr. Cai, I just heard that Lao Duan said that you also have something to do with me?"
Mr. Cai won. He wiped the non-existent water vapor on his glasses and calmed down: "Yes, Director Gao, two things and one thing. It seems that you and Duan Gong have solved it just now."
He didn't know if it was really solved, but judging from Duan Gong's appearance, it should be fine.
Gao Zhendong nodded: "What about the other one?"
Mr. Cai pointed to the test results of the tungsten-molybdenum alloy that Lao Duan had just given to him. He had never seen this thing before. , but I know what it is.
“I’m sorry about this. When I was at the Carbon Research Institute, I overheard some test results of your material. It was very useful to us. I couldn’t help myself and came here. It was a bit presumptuous. Sorry." Mr. Cai said politely.
Gao Zhendong smiled and said: "Mr. Cai is serious. This is not a confidential thing. It is a material that I trial-produced on a whim. What aspect of it is Mr. Cai interested in? Let's communicate."
Really no confidentiality? Maybe this thing wasn't kept secret to begin with, but since you did it, it's hard to tell.
However, Mr. Cai did not dwell on this issue. Instead, he talked about his needs: "Can I see its complete performance and test results?"
He heard these contents. A small part, but the complete one has never been seen.
Gao Zhendong handed over the test report: "Whatever." Since he is a user of high-performance graphite throat linings from the Carbon Research Institute, his origin is self-evident, it is an institute related to rocket engines. And it's not an ordinary institution. As far as Gao Zhendong knows, the material is used on large and medium-sized flying monkeys.
However, the range of large and medium-sized flying monkeys is actually quite wide. It’s hard to say which one they are. Of course, there are not many models currently under development.
Mr. Cai read the test report carefully, his expression became more and more excited. He couldn't find anything after trying hard to find it. It took no effort to get it.
Gao Zhendong did not disturb him. Gao Zhendong maintained the highest respect for them.
After a long time, Mr. Cai raised his head: "Director Gao, this material is very meaningful to us. I would like to ask, can this material be produced stably?"
He didn't even ask. Cost issue! Gao Zhendong thought to himself.
The phrase "stable production" includes a lot, such as whether the technology and process are stable, whether they are obtained from outside but not copied, whether there are stable sources of raw materials, etc.
Gao Zhendong smiled and said: "This is no problem. This thing was produced by me and our factory's equipment using our factory's equipment. However, it uses a relatively scarce metal, which accounts for a large proportion, so it is very large." Not available in batches for the time being, but no problem in small batches. "
Molybdenum is used in it, accounting for up to 50%. If this is used as a common material in large batches, there will be some trouble. The remaining tungsten will not be used. Having said that, we are a country where even shotguns use tungsten alloy projectiles.
Mr. Cai heard this, but he was not disappointed. He was overjoyed and said: "Small batch is fine, small batch is fine."
Hearing his words, Gao Zhendong probably knew what he was going to use it for. .
There are really too many conditions given, the range to guess is too narrow, and the possibilities are too few.
Users of graphite throat linings must be rocket enthusiasts.
It is impossible to use tungsten-molybdenum alloy to make rocket engine throat lining. For them, the density of tungsten-molybdenum alloy is too high. When the performance of graphite throat lining is similar to that of tungsten-molybdenum alloy, it is definitely Graphite is preferred.
Similarly, the engine casing and nozzle are also unlikely. Although tungsten-molybdenum alloy can be used in many places, the main test projects Gao Zhendong sent to the Carbon Research Institute are all around the rocket. It is used in high-temperature applications, so the direction that Mr. Cai can apply after learning the test results will probably be in this direction.
High temperature application, not throat lining, not nozzle, not engine casing, and as long as the batch is small, there is only one possibility.
Gao Zhendong smiled and said: "Well, this thing is indeed suitable for use as a gas rudder."
As soon as this statement came out, Mr. Cai was directly assigned there. It was impossible! ! ! ! ! How did he know what I was going to do with it?
Is this a spy? No, no, you're kidding, it's impossible to expose yourself as a spy, not to mention judging from his situation, this is simply a fantasy.
Then how did he know that I was going to use it as a gas rudder? You must know that these days, even military workers, most do not understand what a gas rudder is and what is the difference between it and an air rudder. Did he just rely on his own knowledge and guess what he said? This is incredible.
The gas rudder is a device that controls the steering of the missile by deflecting it at a certain angle in the gas flow of the rocket engine.
Compared with air rudders, it has high efficiency, can be used at low speeds, and most importantly, can be used outside the atmosphere!
There are also disadvantages. The working conditions are harsh and the requirements for materials are high. When the rocket engine stops working, it stops working.
Gao Zhendong didn't have any psychological burden to say it directly. You didn't say it, so I just guessed it. However, he still added: "I'm also going to use it as a gas rudder."
< br>This thing is suitable for use as gas rudders for all missiles. Its mechanical properties, processing properties, melting point, ablation resistance, thermal shock resistance, storage performance, etc. are all top choices.
The graphite material is not good and its strength is not as good as this thing. The ring-shaped member is okay, but it is not so suitable as a protruding object working in high-pressure, high-speed, high-temperature airflow for a long time.
In that kind of environment, tens to hundreds of seconds can really be considered a long time of work.
Hearing Gao Zhendong's words, Mr. Cai felt a little relieved. It turned out that he was going for the gas rudder materials in the first place. This makes sense.
However, Mr. Cai was still shocked. It’s okay if you just wanted to make a gas rudder material from the beginning, but you can guess that I also want to use it to make a gas rudder. This is amazing.
But he no longer cares about this, but wants to settle the matter as soon as possible.
"Director Gao, can you process components of this material as required?"
Gao Zhendong nodded: "No problem, I have a whole research laboratory here, no problem in processing small batches, and the processing performance of this material is good, it can be used for rolling and forging cars."
Processing performance of tungsten Generally, it is too hard, but after forming the tungsten-molybdenum alloy, it becomes much better.
Mr. Cai was overjoyed and then thought of another question: "What is the confidentiality level of your factory?"
If the confidentiality conditions are not enough, it may not be able to produce this thing.
Gao Zhendong smiled: “There are special workshops and requirements, I can’t tell you more.”
Mr. Cai, who was boomeranged by him, was very happy. This was enough. Mr. Cai was not interested in knowing more. Everyone knew who was not a confidential personnel.
The rest of the things will be easy to handle, but it doesn’t need to be done here, and it doesn’t need to be done by the two of them in person. Duan Gong hasn’t come back yet, and it will be very troublesome to fight the confidential passage. While waiting for Lao Duan, they chatted casually.
"Director Gao, I see that you are also very interested in computers. Will it be of great help to you in researching materials?"
These days, the field of computational chemistry basically does not exist. It is basically impossible to simulate the empirical model, so Mr. Cai’s question can also show that he understands chemistry to some extent.
Gao Zhendong shook his head: "Well, I'm very interested. I made the DJS-59. However, in terms of materials, decisive assistance is not enough for the time being. Some auxiliary calculations can."
"Oh, it is already very trouble-free to assist in calculations. We got this thing, which will be of great help to our work."
Unlike making materials, for those who make Sky Monkeys, having a computer can indeed be even more powerful. effect.
There are so many things that can be calculated in aerodynamics, astronomy, ballistics inside and outside the atmosphere, changes in the center of mass of rockets, and control laws.
These words made Gao Zhendong very happy. Isn’t this the result I want, hahaha.
But at this time, Mr. Cai realized what the first half of Gao Zhendong's words meant. It wasn't that he was slow, but that he didn't think in this direction at all in the first place. It was simply science fiction.
He suddenly looked at Gao Zhendong, with a look of shock on his face, and his mood swings were even more intense than when Gao Zhendong told him just now that he wanted to use tungsten-molybdenum alloy as a gas rudder.
"Director Gao, you mean that you designed the DJS-59?" This was so magical that his tone trembled slightly.
Gao Zhendong nodded: "Well, I did it last year, and then handed it over to the computing institute for mass production. As long as I can help you, it means that my hard work was not in vain."
At this time, Mr. Cai remembered that among the authors of all DJS-59 textbooks, software instructions, assembly language textbooks, and even the latest C language textbook, one name has always been ranked first, Gao Zhendong.
So this Gao Zhendong is that Gao Zhendong? This can't be blamed on Mr. Cai's poor memory. It really makes no sense. Reality is far more magical than fiction.
