Chapter 443 The development of fire control system
If a college graduate's graduation design is a nuclear bomb or even a nuclear reactor, it will definitely be considered a lunatic by ordinary people.
However, you can also see news from some third-rate tabloids saying that a college student assembled a nuclear reactor in his own garage.
This is the technological progress. It may take a long time to develop a nuclear bomb in the early stage, but after the accumulation of time, it will be easier for people to study it later. Even in the developed United States and the Soviet Union, there is no need to try it out.
, just simulate it through a supercomputer.
In terms of tank sights, although this disturbed fire control system sounds difficult, and is even equipped with an introduction project of the L7 tank gun, in fact, this fire control system has long been behind.
The advanced fire control system is a stable and disturbed fire control system. The biggest problem lies in the matching of digital ballistic computers in the car. Now, the first machine factory has solved this problem by the most professional computers in the country.
So if you help, this kind of computer will be created soon. So it is not particularly difficult to use it to match and add a light spot inside.
Of course, even so, it is still too difficult for Xiaoyu. However, this system is definitely not something she has to complete alone. There is Professor Cao behind her. Professor Cao will definitely give various guidance. At the same time,
With Wang Xiaoqiang cooperating with computer programming and Qin Zhenhua next to him, what can I do?
Of course, this graduation design project will definitely be carried out in the first machine factory, which means that after Xiaoyu comes back this time, the first machine factory will be one of her main workplaces, although there is still one
It took more than a year to graduate. Before graduation, she only returned to Capital Institute of Technology when she needed it in sporadic times, and most of the time she spent in the Yimai Factory.
This means that you will have more time to spend with Brother Zhenhua in the future.
The premise of all this is to have Yimai Factory accept this project. Now, the main person in charge has made the decision, and Wang Xiaoyu's excitement is indescribable.
Mr. Zhu was beside him, looked at Professor Cao, and then smiled. It seemed that Professor Cao was determined. He killed many things in one fell swoop.
Qin Zhenhua had no choice but to spread his hands: "Professor Cao, your college is too ridiculous, right?"
When he said this, Wang Xiaoyu became unhappy and pouted: "What? You, an outsider, have you the right to comment on the arrangements of our college?"
"Zhenhua is not an outsider. When the graduation design is completed, you can sign Zhenhua's name on the instructor later." Professor Cao said from the side.
Qin Zhenhua shook his head quickly when he heard this, "Okay, I'm afraid of you, sign my name, what does this mean? I don't want to be a nominal teacher in your college. I'm not even a college student, how can I be a nominal teacher in your college?"
I've raised my head.
The topic was quickly reversed by Qin Zhenhua. He continued: "This disturbed aiming system is still behind after all. What our second-generation tanks still need is a stable aiming system. How has the progress been made in this regard?
”
Last time he went abroad, Professor Cao went out with him. When he came back, he got his wish and bought a second-hand NM-60 four-axis single-sided precision mill. Even because the country lacked foreign exchange, Qin Zhenhua got it from Mercedes-Benz Heavy Truck Company.
All the bonuses of 10,000 marks were used.
Qin Zhenhua didn't care about personal gains and losses at all. He puts the interests of the country first in everything. The help he provided to Professor Cao was naturally to enable Professor Cao to complete the research and development of this project as soon as possible.
"This system is currently under active development," said Professor Cao. "However, so far, there is still an important project that has not been conquered, so even if it is developed, it is still flawed."
"Glow light night vision device?" Qin Zhenhua asked.
Professor Cao nodded. He was indeed a sensible person. As long as he said that, his heart would be like a mirror.
Domestic tanks have not had night combat capabilities for a long time, or they also have night combat capabilities. They rely on tank hands to supplement vitamin A and eat more cod liver oil.
Technology is constantly developing, but in China, it has always been out of date.
In fact, as early as when the 59 tank was introduced, the night vision device of infrared headlights on the T-54 had matured. It is an active night vision method. At night, an infrared headlight is used to illuminate the road, because
It is not a visible light category, which cannot be seen by the naked eye, but it can be received by the tank's sights. Therefore, when it is shined and reflected back, the tank hand can see everything ahead clearly in the dark.
However, this method is quite primitive and backward. As long as there is an infrared receiving device on the opposite side, those infrared headlights are a way to expose their targets brightly, and the other party will hit each other accurately.
However, even such a device is not available in China. The domestic 59 tanks do not even have infrared headlights, and they have almost no night combat capabilities.
It was not until the 69 tank that it began to be equipped with infrared headlights, which had some night combat capabilities, which only solved the problem of whether there was or not.
The low light night vision device has been a relatively mature night vision device that has been developed over the years. Compared with infrared headlights, it does not emit any signal, only receives faint light, and then continuously amplifies the signal to change it.
If you are strong, you can see everything in the darkness clearly.
Unless there is absolutely darkness, you can't see your five fingers, this night vision device can work as long as there is a faint starlight.
"The low light night vision device has now developed to the third generation." Professor Cao said: "The first generation was in the early 1960s, using multi-alkali photocathode, optical fiber panels and concentric sphere electronic optical systems, first-level
A single tube can achieve about 50 times brightness gain, and through three-stage cascades, it can be visible to the naked eye."
"The second generation, using microchannel plate electronic multiplier, the gain of the first stage is as large as that of the original third stage, realizing the revolution of the low-light night vision device. Now most of the products abroad are still the second generation, but,
If you want to talk about advanced ones, it is already the third generation."
"The third generation emerged in the development of semiconductor technology. The development of gallium arsenide negative electron affinity potential reflective photocathode theory and the implementation of process have triggered a revolution in the field of low light night vision. It is related to the second
Compared with the second-generation low-light night vision device, the sensitivity has increased by 4 to 8 times and the life span has been extended by 3 times. In the dark night, it also has good observation ability."
"As for us, we don't even have the first generation of products now." Professor Cao said: "In this way, even if our fire control system is developed, it will continue to retain the defects of night battles."
