Chapter 802 Problems with Laser Guidance
Silly Zhu actually didn't think of going to Yi Zhonghai and the others. He just felt that it was right to discuss this matter with a buddy. As for the outcome of the discussion, he really hadn't thought about it.
Now that he heard Gao Zhendong's suggestion, he felt relieved! Got an idea! As for the idea, he didn't give it much thought.
Anyway, what you want is the feeling, the actual idea is not important.
"Hey, yes, yes, you will come with me later. What am I missing...can you help me with the total?"
"Okay, how about a TV? Four hundred and thirty." Gao Zhendong simply brought out some food and drinks, and the two of them discussed it while drinking. He would have a big deal together.
"How much? Four hundred and three? Can you really get it?" This price undoubtedly scared Shazhu, but TVs are really rare. To be honest, he also knows how many people have money for TVs. If you can't buy it yet, it's not a matter of 430.
"It's so new. Just tell me whether you want it or not. There was a color TV originally, but the price of that thing is more than doubled. If you two are willing, I can also get you one. Let's talk about it first. There is no signal now. He can only be a black and white user." For Gao Zhendong, as long as it is within the production scope of the Twelve Machinery Department, there is nothing he can't get, but he rarely takes action.
When he heard the color TV, Shazhu's eyes lit up. What he wanted was this unique one. But when he heard the price of almost a thousand yuan and the ready-made TV without even a signal, he quickly calmed down.
Gao Zhendong didn't even own a color TV, mainly because we don't have a TV signal for that thing at all. Color TV signals were originally developed in 1973. Now, although we have color TVs 10 years ahead of schedule thanks to Gao Zhendong’s efforts, we do not have color TV signals. The TV stations have not yet reacted. Now after digesting and assimilating The color TVs produced have one goal - export.
"As for the TV, Sister Qin and I will discuss it. Let's forget about the color TV. It's too painful, hehe. What about, three turns and one beep, you can handle the third turn for me first."
Three turns: sewing machine, bicycle, watch.
Gao Zhendong turned around and took out the ticket from his body: "Hey, this is easy to handle. Come on, come on, you can choose it yourself."
Looking at the handful of tickets in Gao Zhendong's hand, Silly Zhu's eyes widened, but he was not greedy either. He picked two bicycle tickets, two watch tickets, and a sewing ticket and stopped.
Gao Zhendong was willing to help out of love, but if he took a bunch of tickets to resell them regardless of whether he could use them or not, that would be a mess.
He couldn't even digest these 5 tickets, and he had to save two months of money to buy them all. He also knew that Gao Zhendong must have cash on hand, but he couldn't catch one person to collect the wool. He had already reached the limit of his ambition to solve so many votes. It would be a bit too much to ask him to borrow money again. He still didn't want to extend his hand unless it was absolutely necessary.
"Why don't you get some cloth tickets or something? Not to mention you two, your sister and her children must get new ones, right? By the way, there is also Mrs. Jia." Like Silly Zhu In this situation, there is really no need to be careless at all. You have to take care of the palms and backs of your hands, otherwise you will be remembered for a lifetime if you are not careful.
"Hiss~~~~~~Yes, you are still thoughtful about this matter." Silly Zhu felt that Gao Zhendong was still knowledgeable, and he had not considered these things himself.
"But I don't know how much cloth is needed. Please wait until I discuss this with Sister Qin, and then come to you for it after I have determined the quantity." Silly Zhu is still the same, not greedy.
"Yeah, okay." Gao Zhendong had no intention of throwing tickets at others.
The two discussed it for a long time. To be honest, Gao Zhendong didn't even think about it so much when he got married. When he got married, he was completely hands-off.
The two chatted for an hour or two, but actually they didn't say much. They could hear Shazhu sighing with emotion all the way. As an old bachelor born in 1935, it was normal for him to be excited when he was about to get married.
When Silly Zhu left, his tongue was full: "Zhen... Zhendong, tomorrow you and I will look for... to find the uncle."
Gao Zhendong agreed wholeheartedly and sent this brother back to the middle courtyard. To be honest, Gao Zhendong was the only one who sent him back. If it had been anyone else, He Yuyu would have scolded him.
——
But the next day, Gao Zhendong finally failed to go to Yi Zhonghai with Shazhu. The next day, he received a call asking him to go to Chunlei Factory.
Gao Zhendong estimated that it was about the laser-guided bomb. Apart from this, Chunlei Factory had nothing else to do with him. As for the remote spreader, it has now begun small-scale production and trial use, and it is basically completed.
There is no way. If there is a problem with this thing, you really have to go to the scene. You can't just fly to the capital with a bomb and drop it. That would be great fun.
Gao Zhendong first called his father-in-law and arranged things for Lou Xiaoe. In fact, there was nothing to worry about. Lou Xiaoe was very safe there. Now the old couple really held it in the palm of their hands for fear of flying away, holding it in their hands. The fear melted in his mouth.
Then he made a special call to the cafeteria and told Shazhu that he could either wait a few days or go up first. Shazhu chose to wait a few days without hesitation and asked him to go up by himself. He was heartbroken.
With people, Gao Zhendong flew there directly. It was very convenient for the National Defense Work Committee to arrange a plane ride along the way. Although he couldn't reach the destination, he could save more than half of the journey.
It’s still that flying tractor that is extremely safe but has the lowest comfort. I wonder if the National Defense Work Committee also knows about the safety of this aircraft and is very confident, so it specially arranged this thing for him. Anyway, Gao Zhendong doesn’t fly. I have ridden in other models, and it is amazing when I think about it. Chunlei Factory is not very far from the capital, but the speed of the flying tractor is slow, so it still took a while to fly there. After getting off the plane, it took more than an hour of driving to get to the location of Chunlei Factory.
Chief Engineer Zhang of Chunlei Factory had been waiting at the factory gate early. Judging from the pile of melon seed shells in front of him, he should have been here with people since the pick-up car set off.
"Mr. Gao, you're here, welcome. Come on, let's eat first. You've been busy traveling all the way. It's about the same time. Let's eat something first to cushion our stomachs."
Gao Zhendong didn't refuse. Firstly, it was indeed time to eat. Secondly, one of his accompanying comrades had vomited all his breakfast on the plane and had to be replenished.
After dinner, Mr. Zhang took Gao Zhendong to the conference room, where a large amount of materials had been prepared.
"General Engineer Gao, please take a look at our design first and get familiar with the situation, and then we'll talk about other things." Mr. Zhang was not in a hurry to solve the problem.
Gao Zhendong opened the information in front of him and read it carefully.
According to Gao Zhendong's suggestion, Chunlei Factory did not choose the laser beam guidance method. Laser beam guidance has problems that are difficult to solve when used on laser-guided bombs.
First, the guidance distance is short, and second, the laser beam basically requires that the emitter and the irradiator are the same. Otherwise, it will be difficult for the launched missile to enter the range of the laser beam, and beam guidance will be impossible.
These two basically determine laser-guided bombs or airborne missiles, which are rarely guided by laser beams.
The latest chapter of this book
Take a look at the 16-9 book bar!
Following Gao Zhendong's suggestion, they chose laser semi-active guidance. The principle of this thing is actually the same as radar semi-active guidance, but the guidance medium is changed from radar waves to lasers, which are all electromagnetic waves anyway.
Compared with radar, lasers are inherently accurate in guidance due to their excellent monochromaticity and directionality. If the weather is suitable, the hit rate is very high.
Gao Zhendong felt quite normal watching it from beginning to end.
"Mr. Zhang, what problems are you encountering now?"
Mr. Zhang first took out a test record: "Mr. Gao, take a look at this first."
Gao Zhendong looked at it carefully: "It's very good. The hit rate is over 85%, and the anti-interference performance is also good against the interference of thin rain and fog."
Just looking at this test record, it can be said that Chunlei Factory has basically achieved the goal of developing laser-guided bombs. The universal seeker they developed can be installed on various calibers with tailfins and control surfaces of different sizes. On aerial bombs, the maximum weight can reach 1,000 kilograms.
The tail fin is immovable and is responsible for turning the bomb. It is the front half of the kit, the front control wing that is connected to the seeker. The advantage of this is that it greatly simplifies the design of the kit. The tail fin is basically not needed. No matter how hard you put it, this thing is even completely separated from the first half.
For some bombs whose tail fins already provide sufficient stability, it is even possible to install only the head guidance and control system without touching the tail fins.
The test records also show that Chunlei Factory's efforts are effective. The bomb's hit rate is very high, more than 85%, and this hit refers to a direct hit within a few meters of the bull's eye, rather than a large target area. , this is a hit rate and hit accuracy that ordinary bombs cannot achieve even with dive bombing technology.
That's why Gao Zhendong said they did a good job.
Mr. Zhang nodded: "If we talk about the effect of a single strike, indeed, under your guidance, we have achieved good results, but now we have encountered a new problem."
After speaking, he took out another test record.
"Mr. Gao, you see, this is the result of our simultaneous attack test with multiple munitions. It is not very ideal. This attack method was proposed by comrades from the Air Force and was not part of the original research plan."< br>
Gao Zhendong looked at the requirements and couldn't say that it was the Air Force's fault. For some solid targets, in order to complete the strike in the shortest time and reduce the time exposed to enemy anti-aircraft fire, this method uses multiple ammunition at the same time. The way to attack the target is indeed necessary.
