Chapter 23 Laser Guidance Technology Sanmenxia Reservoir Program

Seeing Li Wei's anxious appearance, Zhang Zhimu, Yang Chang and others all laughed "hehe". Yang Chang said: "General Li, if the rocket you are working on now wants to automatically fly to the target, you must first get out the gyroscope we just talked about. The gyroscope is then used to determine its own position and deviation, and then to correct it. ”

"Speaking of which, it's not too early!" Li Wei was in such a hurry.

"There is another way," Zhang Zhimu said, "we can use the kind of radio detectors used on ships today to detect the altitude and distance of your rockets flying up, calculate their positions, measure a few points to calculate their trajectory, and then we can launch commands to control the rudder surface and rest the trajectory." ”

"Hey! It's a bit interesting," Li Wei still knows a little about radio detectors, "The rocket flies very fast, and we calculate the speed ....." Li Wei wanted to say that "the calculation speed can't keep up", but he immediately understood, "Mr. Zhang, do you mean to use a computer to calculate?" ”

"Huh! That's right! Zhang Zhimu smiled and said, "We are desperately spending a lot of money on computers, do you think we are having fun?" ”

"No, no, I knew you wouldn't do anything wrong!" Li Wei was convinced, "However, when I looked at the computers in the computing center, they were all piled up like a small mountain, and we couldn't pull a few cars." ”

"Yang Chang, one of the directions of your computer development in the next step is to miniaturize, and it must be sturdy and durable, so that it can be pulled and used by special vehicles." Zhang Zhimu said, "Of course, there is no need for the computer to do all kinds of functions to meet special needs." Your core processors should be as integrated as possible. It can't be integrated on one piece, it can be divided into several pieces. Monolithic processors, which do not need to be too complicated at the beginning, can start from one bit and slowly develop into four bits and eight bits. With a monolithic processor, rocket guidance equipment can be installed on the rocket in the future, when the rocket sets a target before takeoff, and after takeoff, it can fly on its own. ”

"What's an eight?" Li Wei didn't understand at all, "You just put the computer on the car, cooperate with the radio measuring device to calculate the trajectory, and then correct it!" ”

However, Yang Chang and the others listened to Zhang Zhimu's words, and even though they were all engaged in computers, they were all very shocked. They know that the core processor that Zhang Zhimu said, with the continuous improvement of integrated circuit technology, will not take long to make a monolithic, such a simple computer, can be installed on a rocket, and then with a gyroscope can fly by itself, which is simply amazing.

Yang Chang said: "Mr. Zhang, this goal will not be too far. We have thoroughly understood the technology of the processor, and the next step is to improve the integration of the problem, our brothers on the integrated circuit side are also very attentive, and their progress is also very great. I think that if any device is equipped with a computer, then it will be like a tiger with wings! ”

"Let me tell you so!" Zhang Zhimu said, "In the future, all kinds of our instruments and meters will use monolithic processors, so that all kinds of corrections will be completed automatically." Even our home appliances use monolithic processors. This thing will be ubiquitous and will have a great impact on our entire social life and production.

"Oh my God! I think it's too early for that! Li Wei said disappointedly.

"A journey of a thousand miles begins with a single step!" Zhang Zhimu said, "If you don't start doing it today, you will never have a harvest in the future." ”

"Alas! I can't make any effort no matter how anxious I am," Li Wei said, "and what's going on with the guidance of the line-of-sight range you mentioned!" ”

"That's right, Mr. Lu's students came up with a ruby laser very early. In physics, I told you that lasers are very well collimated, and we can use lasers for guidance. ”

"Lasers can also guide?" Li Wei also came to the spirit.

"Well, we shine a laser beam at the target, because the target will reflect the laser in all directions. Let's assume that if a rocket flies in the direction of the target, there will be a laser reflected on the rocket. We have a set of filters on the front of this rocket that filter out all other light and only allow this laser wavelength to pass through. Behind the filter, we use a convex lens to focus the reflected laser, and the focused laser falls on a plane perpendicular to the direction of the rocket, which is composed of four sectors. If the light falls on the left fan, it means that the laser light comes from the right side of the rocket's forward direction, that is, the rocket deviates from the target direction to the left, then the rudder should be controlled to correct to the right. In this way, we can constantly guide the correction rocket to the target as the rocket flies towards the target, until the target is destroyed. Zhang Zhimu was drawing pictures on the blackboard while introducing them to Yang Chang and Li Wei.

"It's very simple!" Li Wei said, "However, we need someone to use the laser to shine on the target all the time!" ”

"You're right, this way you need someone to point the target with a laser." Zhang Zhimu said, "Let's make this assumption, Li Jing and their special forces ambush outside the enemy's camp, hide up, choose the right time, use a laser to irradiate the enemy's command tent, you launch rockets at the target from a distance, wait for the rockets to reach the sky above the camp, receive the laser reflected by the target, correct the direction and smash into the target's tent, and directly destroy the enemy's command center, what will be the effect?" ”

"Oops! In that case, our rockets will be a magic weapon! Li Wei said, "However, if you take a laser and shine on others, they can also see it!" ”

"We'll experiment with ruby lasers first, and then we'll work on infrared lasers. Then the human eye will not be able to see! Zhang Zhimu said.

"Oops! Interesting," Li Wei said, "Yang Chang, you have to hurry up on this matter!" ”

"Huh!" Yang Chang smiled and said, "General Li, what do you say we don't need to hurry?" ”

"Li Wei, you will soon research a rocket that is not a ballistic flight, just like an airplane, with wings and a rocket to boost the flight. This will allow you to use laser guidance to attack enemy ships! Zhang Zhimu said.

"Huh?" Li Wei touched his head, "In that case, isn't it a rocket that can blow up and sink an enemy ship?" ”

"Huh!" Zhang Zhimu smiled bitterly and said, "Now the enemy's ship is worth silver without a rocket like ours, and we will also suffer a loss if we sink it!" ”

"What?" Li Wei was stunned for a moment and said, "That's not appropriate, but the battle can't be counted like this, sometimes in order to ensure victory, you have to do it at a loss!" ”

"Oh this! The main thing is to prepare for the enemy to be able to build steel-hulled ships in the future. We must have weapons that are generations ahead of the enemy. The cannons and rifles we are using now are known to the enemy, and they will not be able to build them in a short time, but there is no guarantee that they will not be able to build them in the future. We must have weapons that are ahead of our time, and we must have them ready if we don't need them. Zhang Zhimu said.

Yang Chang said: "Mr. Zhang, this has opened up a new field for us. Our people are even more nervous! ”

"The computer school you are preparing to build, although everything has not been built, will start recruiting students this year, and those who can borrow classrooms from other schools will borrow them first. School construction should be accelerated. Your school should not only have a software major, but also a hardware major. In short, everything that can be used in electronics must be available. Four years later, there will be an explosion of demand for computer talents, and at that time, there will not be enough people! We need to take precautions, plan ahead, and recruit as many students as we can. ”

"Good! We also feel that people are not enough for more and more months, and the more they do, the more they do! Yang Chang said.

Li Wei was not very interested in these, "Mr. Zhang, do you think our shells can also be guided?" ”

"Yes, of course!" Zhang Zhimu said, "In the future, it is necessary to study laser-guided artillery shells. This thing is more difficult and needs to be studied later. However, we can study the ** that is dropped from an airplane for guidance. The ** dropped on the plane can be guided by gravity as power, and we use a laser to illuminate the target on the flight, can it fall directly on the target? ”

"This is amazing," Li Wei said, "our aircraft will start mass production immediately, and this guidance ** must be carried out." ”

"I estimated that laser-guided ** is dozens to a hundred times more expensive than ordinary **!" Zhang Zhimu said.

"Oh my God! Is this still something that works? Li Wei exclaimed.

"Have you thought about it, suppose that when the enemy escapes, there is a bridge as a path, and it is difficult for our ordinary aircraft to accurately hit the enemy bridge, but our aircraft carrying laser guidance ** will accurately destroy the enemy's bridge, is this ** worth it?" Zhang Zhimu said.

"That's worth it!" Li Wei said, "Can we settle the big account!" Also, is this also the case, just like a TV radio, the batch size of production is large, and the cost can be reduced? ”

"Of course you can, but you can't change the difference by an order of magnitude. Now there is no need to think about the price, if the country is in danger, what price will have to be paid! Zhang Zhimu said.

Li Wei nodded and said, "What I said is that if the capital of the country dies, you don't have to worry about anything expensive and cheap." We can develop this thing first, we don't have to, we don't need it. Again, it's better to be prepared than to be prepared! ”

Whether it is **, submarines or guided rockets, Zhang Zhimu simply said hello to the relevant personnel separately, and finally had to meet Lu Bingyi to summarize these things and arrange them in a unified manner.

After today's incident, Zhang Zhimu asked Yang Chang: "How is your construction of the pager?" ”

"We reported to Mr. Lu, who was very supportive of this matter, and he asked us to immediately mass-produce pagers. He also said that he would have to think about other things. Yang Chang said.

"That's good! Leave this matter to Mr. Lu, he is an expert in making money. Zhang Zhimu said, "One more thing, I suggest to you, your pager can be connected to two computer terminals. All your user information can be stored on the computer, and the user's payment information and special needs information are very convenient to manage with the computer. For example, message inquiries, as well as those users who have not renewed their subscriptions when they expire, can be grasped at any time. ”

Listening to Zhang Zhimu's suggestion, Yang Chang patted his head and said, "That's right! Otherwise, each of our pagers needs to get a big book to record the message information, and the query is very inconvenient. It would be much easier to plug in the computer terminal! ”

"And! You have to urge those who are engaged in light-emitting diodes to come up with products as soon as possible, and the next generation pager must be able to display the pager number! Zhang Zhimu said, "Tomorrow you will go with me to Master Qingfengzi's side, and we will study the matter of liquid crystal display." ”

"What? LCD? What is liquid crystal? "Yang Chang has never heard of LCD.

"Tomorrow I will go to Master Qingfengzi's side and talk together." Zhang Zhimu didn't want to talk to Yang Chang now, and he would talk about it again tomorrow when he saw Master Qingfengzi.

Zhang Zhimu immediately called Qingfengzi's office and agreed to see him tomorrow, but Qingfengzi went to the smelting field to participate in an experiment and couldn't come back tomorrow, and the office staff didn't know anything else.

Zhang Zhimu had no choice but to say to Yang Chang: "Master Qingfengzi is not here tomorrow, we will make an appointment to go." ”

During this time, it was impossible for Zhang Zhimu to be quiet.

Early the next morning, Lu Bingyi, Tang Jingyao, Duan Jingzhong and Lu Chengxiang came to Zhang Zhimu's office together.

Lu Bingyi, Tang Jingyao, and Duan Jingzhong made an appointment to come together, and Lu Chengxiang had other things to do, so he caught up and came to Zhang Zhimu's office together.

Tang Jingyao's entourage was holding a large number of drawings, and Zhang Zhimu knew that they were the drawings of the Sanmenxia Reservoir.

After everyone sat down, they were not too polite, and Lu Bingyi said directly: "Mr. Zhang, it just so happens that Mr. Lu is also here today, let's talk about the Sanmenxia Reservoir." Several of us have studied it many times, and now we have some ideas about other things on the Yellow River, and we should study them together. Mr. Tang Jingyao has always personally grasped the matter of Sanmenxia, and I don't know how many trips he has made to the field. ”

Tang Jingyao said politely: "This is a matter related to future generations, and it is not sloppy at all." All of us involved in this are 100% careful. What I brought was a drawing of the overall plan of the Sanmenxia Reservoir. As he spoke, Tang Jingyao took the drawings and spread them on the table.

Everyone got up and surrounded them, and Tang Jingyao said: "According to what Mr. Zhang said, first, we must have a certain flood control function; the second is to improve the capacity of ships; the third is to have sand dredging capacity; Fourth, the water level of the reservoir should be controlled, so as not to affect the water level of Weishui upstream of Tongguan; Fifth, it is necessary to have a certain power generation capacity. Our solution is that the dam will not only have floodgates, but also rolling dams on both sides, and when the flood level is too high, the flood can be discharged through the floodgates, and the flood can also be discharged through the rolling dams. The water level of the reservoir ensures that all reefs are submerged, large ships are allowed to navigate, and there are two levels of locks. We have learned from the experience of the Hutuo River Reservoir Dam and the Jialing River and Tianshui Class I Reservoir Dams, which have sand discharge outlets at the bottom and sand flushing holes at the upper part to assist in sand discharge. Of course, we also have to install several large generators. ”

Lu Bingyi said: "Another thing is that the water level of this reservoir has risen, and there will be a lot of more water on both sides of the reservoir to irrigate the land. It is also much easier to carry water for irrigation at a higher level. ”

"Huh! What interests me the most is that the big ships can easily pass through, otherwise this section of rail transportation will be too stressful. Water transport is too affected by seasonality. Lu Chengxiang said.

"The amount of work in this reservoir is the Hutuo River Reservoir, and the two reservoirs can't be compared, the amount of work is too large. I'm afraid Mr. Tang will have to preside over this matter himself! Zhang Zhimu said.

"I don't feel at ease when I leave this matter to someone else." Tang Jingyao said, "However, now we can do things with a lot of people, I just go to help the helm, we have not only done a lot of projects over the years, the most important thing is that we have trained the team, but also trained some generals." When we operated the Hutuo River Reservoir, we almost used our kiln to say that there was a living force, but now it is different, and Mr. Zhang can rest assured about the personnel! ”

"This is probably the longest preparation time for our kiln, and I originally wanted to let everyone discuss it at the people's congress, but after thinking about it again, time does not allow." Zhang Zhimu said, "We all know about this matter. I think that's it, don't hesitate to do this, let's hold a meeting of senior cadres in Yaogang, discuss it, if there is no other opinion, let's start it immediately! After speaking, he asked Lu Chengxiang, "Mr. Lu wants to prepare the silver!" ”

"Huh! You don't have to worry about the money! Tomorrow if you have time, I will organize people to make a good budget for the project. We do engineering, and we need to be wide and strict. But don't be like the Hutuo River, too much! Lu Chengxiang said.

Lu Bingyi said: "But isn't it? If we had known that the Hutuo River Reservoir had cost so much money in the end, we would not have dared to embark on this project. But now it seems that the Hutuo River project is the most successful project that we have done so far. Needless to say, electricity meets our needs, and how much more water is available around the reservoir to irrigate the ground. After the reservoir was built, the lower reaches of the Hutuo River have not been interrupted, and there have been major floods. ”

Duan Jingzhong said: "The first reservoir on the Yellow River has the significance of surpassing the Hutuo River!" As long as this reservoir is completed, the sea transportation from Tongguan to Dahai will be unimpeded. Many of our kiln goods can be loaded from Tongguan and go directly to sea. According to Mr. Zhang, we mentioned Tongguan when we went to the sea. ”

Lu Chengxiang said: "To be honest, we can say today that we have the strength to build such a project that no one dared to think of since ancient times." Not only do we have the money to build such a large project, but our reinforced concrete is also enough to meet the needs of the project. In particular, we can basically meet the needs of our tractors and various excavators. We are lucky to have the opportunity to do such a good deed for future generations in this life! ”

Lu Chengxiang, who has always been calm, spoke very emotionally, and it also infected everyone present.

Tang Jingyao said: "Not only that, but I also brought the plan for the Hukou Reservoir this time. Of course, it hasn't been designed yet, it's just a simple solution! ”

"Oops! The wonder of Hukou Waterfall is a must in the world! Lu Chengxiang said in surprise.

"But this spectacle has also cut off the entire Yellow River!" Tang Jingyao said.

Zhang Zhimu smiled bitterly and said, "Hehe! Don't think about the spectacle yet, let's talk about your plan! ”
