050 Rockets also have to do wind tunnel experiments
Thanks to Tianhai Xiangyun Dada for giving 1888 coins for generous rewards.
"To be precise, the architecture we are currently using should be an instruction set. As you said, the chip circuit is not sure whether our domestic monocrystalline silicon production can meet our performance requirements..." Liu Yijiu said to Liang Qiang after a moment of surprise.
Since Liang Qiang has researched on this, this is the best.
In this regard, it can be said that it is basically a blank in China and a weakness in materials. The production process of single crystal silicon is not complicated, but the process requirements are very high. He wanted to create a light brain with faster computing speed and better performance, but found that there were not many possibilities in this era.
The main electronic component of the optical brain is the memristor, and the carrier is graphene that will only be developed for more than 20 years! It is very easy to prove that graphene exists, but to study this and put it into practical application, there are too many funds and scientific research equipment required.
The most suitable one is obviously silicon-based chips that have dominated the world for more than half a century.
"Comrade Xiao Liu, this aspect of materials is not a big problem. If we talk about industrial production, our process cannot provide high-quality materials. Under laboratory production conditions, there is still no problem with a small amount of materials used for experiments." Liang Qiang knew what Liu Yijiu was worried about.
Materials are the weakness of the country.
"Does our base have this ability?" The materials research side in the second zone is mainly responsible for the research of some metal materials. The most important thing is strategic materials related to aerospace, such as high-temperature alloys, titanium alloys, aluminum alloys and alloy materials used in metal machining.
In fact, each of these departments has an organizational structure in each partition, but it is not as professional as a specialized partition.
Just like the state-owned factory, sparrows are small and have all the internal organs!
"This is not very clear. However, there is no hope for the materials in the second zone. What we can count on is the fourth and seventh zones that are specifically responsible for electronic research. When it really doesn't work, we can only ask for help from the space base next door. They are studying guided missiles. When the missiles find targets during flight, they need chips to calculate. They have researchers in this regard..." Liang Qiang's understanding of the base is obviously better than Liu Yijiu.
Liu Yijiu has not been in the base for a long time, but he has only been to the 8th district of the tertiary industry, and has never even been to the tertiary materials area 2 and tertiary electronic area 4 near the tertiary area!
"It's better to get the design drawings out first. When trial production, then consider the material aspect." Whether the material performance can meet the production requirements? This needs to be measured after trial production. The better the material, the better the effect. This is what everyone knows, but in this regard, it is not possible to have good materials if you want good materials.
Materials are the shortcomings of the Republic's military industry.
Everyone knows that the Republic has no problems with space rockets and missiles, but it is very weak in aviation.
The reason is that the aerospace rocket engine is a disposable product, and each missile or rocket engine is scrapped after use. However, aircraft engines are different and need to be used repeatedly.
When Liu Yijiu heard that there was a chip project research team at the aerospace base, he was immediately moved.
But he has no choice now. The space base will probably not belong to their strategic reserve base.
"What a complicated circuit diagram design?" Liang Qiang screamed when he saw Liu Yijiu's circuit design drawing that had not been completed.
Liu Yijiu is just a young man who has just left the school gate. How could he design such a complex circuit diagram? This obviously makes people think it is impossible.
"This is just part of the circuit diagram. Nowadays, large-scale design research on the miniaturization of integrated circuits has begun abroad. Their small processors have more than 7,000 transistors. At their speed, it is very likely that integrated circuits with tens of thousands of transistors will be launched in the past two years..." Liu Yijiu shook his head and said.
Without a brain, there is no oldest computer. He has no way to use these auxiliary equipment and can only rush on the drawings. He has no way to free up chips with better performance. Unless the supercomputer at the base is used for him, but is this possible?
At least not possible now.
"We can't understand..." The other maintenance personnel who followed Liang Qiang were really not very clear about the circuit diagram.
Liu Yijiu has already drawn dozens of A2 drawings, but he said that there is no one-quarter of this...
"It's okay, just take it slowly. These are logic circuits, which are not much different from our supercomputers. We don't use circuits used by large computers, but miniaturize them, which allows researchers to use personal computers that each have..." Liu Yijiu's words reassured Liang Qiang and his group.
Instead of being idle in the mountains, it’s better to design this with Liu Yijiu!
"Uncle Wang, what's the matter? I'm so anxious to look for me?" Liu Yijiu didn't expect that Wang Shunyi hadn't entered the base for just two days, so he called him and asked him to hurry to the area where the rocket launcher was researching.
After arriving, I saw a group of two old men with dark circles, bloodshot eyes, and their spirits were in an excited state.
"Comrade Liu, you are finally here!" Qin Yuan rushed towards Liu Yijiu with excitement when he saw Liu Yijiu.
Liu Yijiu watched him wandering when he walked, worried that the old man, who was in his fifties, would fall to the ground, so he could only stand there in depression.
"Come and take a look at the new design drawings of our rocket body..." Wang Shunyi also shouted at Liu Yijiu with red eyes.
"How many days have you not slept?" Liu Yijiu asked in surprise. These old men should have not slept for several days! He even regretted telling them how to make the rockets fly more stable.
"After you proposed the finite element analysis and how to better adapt to aerodynamics, we are improving the appearance design of the missile body. But how do you look at this thing? How do you look at it? It's a missile rather than a rocket!" Wang Shunyi said to Liu Yijiu excitedly.
"It doesn't matter whether the appearance looks like a missile. After all, this thing is much cheaper than the production of missiles. As long as it can achieve the effect..." Liu Yijiu was a little depressed by the conservative thinking of these old technicians.
Rockets, missiles, and these are simply not distinguishable based on their appearance. They may look like missiles, but their internal structure is a simple rocket; they may look like missiles, such as the thing in front of them, which is actually a rocket.
From the beginning, the standard for distinguishing rockets from missiles was whether there was a guidance system.
As the range of the rocket becomes longer and longer, reaching hundreds of kilometers, for better accuracy, the rocket has also begun to install guidance parts...
"Our thoughts cannot be limited to this aspect. Just let the weapons we designed use the simplest structure to achieve the maximum power. We don't need to consider anything else." Liu Yijiu's words touched these old experts very much.
They have been bound by various rules and regulations for too long.
Therefore, Liu Yijiu has successfully made a sniper rifle that has been built many times in China and has not been produced for a long time. Now he has started a small batch trial production stage...
"If there is no problem with data verification this time, we will start sample trial production..." Wang Shunli said to Liu Yijiu happily.
"Don't you need to do wind tunnel experiments?" Liu Yijiu was speechless.
To detect the impact of air resistance on the rocket's flight posture and movement during high-speed flight in the air, a wind tunnel experiment must be conducted.
After all, these things are very fast.
"This is not a strategic missile, what wind tunnel experiment is going to do!" Qin Yuan said indifferently. "Anyway, we don't need much accuracy. At that time, we can launch hundreds or thousands at a time to launch a series of attacks on the enemy..."
Qin Yuan’s statement is not wrong.
But Liu Yijiu thought it was wrong.
"Uncle Wang, Teacher Qin, I want to ask you, what is the purpose of studying rocket launchers with such long-range range? The fast launch speed, high power and low cost are its own characteristics. If the error diameter of this bullet point is 500 meters, or even one thousand meters or higher, what else can these rocket launchers be used to bomb the enemy's city..." Liu Yijiu's mouth was tilted, and he asked Qin Yuan and Wang Shunyi very seriously.
His words made them fall into deep thought.
"Xiao Liu, ours is just a rocket launcher, not a missile..." Qin Yuan emphasized.
"I know. But our rocket has a range of more than 90 kilometers! There is no guidance system. If the impact of the mainstream air on the ballistic during flight is not tested, who knows how many kilometers it will be? I think we cannot pursue range and power too one-sidedly, but must consider the accuracy issue! For example, in the Vietnam War, if the US military's missiles can be controlled within a radius of five meters or even more accurately, how long can Vietnam take?" Liu Yijiu's words made a group of old technicians look at each other.
They did not expect that after living for so many decades and doing such a long research work, they were actually educated by a young man who had just left school for a while.
"It is not possible to just verify theoretical data. Wind movement experiments must be conducted to obtain more experimental data, so that our rocket shape design can be more aerodynamics and can also have high accuracy without installing the system! What we are studying is not just rockets! But missiles!" Liu Yijiu said gritting his teeth.
With limited funds, these funds must be made to achieve more results!
