Chapter 802 Laser Guidance Problem
It’s not that Sha Zhu didn’t think of looking for Yi Zhonghai and the others. He just felt that it would be right to discuss this matter with a buddy. As for what the result of the discussion would be, he hadn’t really thought about it.

Now, after hearing Gao Zhendong's suggestion, he felt that he had it all together! He had an idea! As for whether this idea was the same as not coming up with it, he didn't think about it much.

Anyway, what we want is the feeling; the actual idea is not important.

"Oh, yes, yes, you can go with me later. What do you need? Can you help me figure it out?"

"Okay then, how about a TV? Four hundred and thirty for one." Gao Zhendong simply brought out some wine and food, and the two of them discussed while drinking. He started with the big stuff.

"How much? Four hundred and thirty? Can you really get it?" This price undoubtedly scared Sha Zhu, but televisions were really rare. To be honest, he knew that many people had money but couldn't buy one, so four hundred and thirty was not a big deal.

"It's so new, just tell me whether you want it or not. We do have a color TV, but the price has more than doubled. If you two are willing to spend, I can get you one. But let me make it clear, there is no signal now, so you can only use it in black and white." To Gao Zhendong, as long as it was produced within the scope of the 12th Ministry of Machine Building, there was nothing he couldn't get, but he rarely had to deal with it.

When he heard the word color TV, Sha Zhu's eyes lit up. This was the unique one he wanted. But when he heard the price of nearly a thousand yuan and the fact that it didn't even have any signal, he quickly calmed down.

Gao Zhendong himself didn’t make a color TV, mainly because we don’t have a TV signal for that thing now. Color TV signals were originally a thing in 73. Although we have color TVs 10 years earlier thanks to Gao Zhendong’s efforts, we don’t have color TV signals. The TV stations haven’t reacted yet. Now, after digesting and absorbing the technology, the color TVs we produce have only one goal - export.

"I'll discuss the TV with Sister Qin. Forget about the color TV. It's too hard to handle. Hehe. Well, three turns and one ring. You can solve the three turns for me first."

Three revolutions: sewing machine, bicycle, and watch.

Gao Zhendong turned around and took out the ticket from his pocket: "Hey, this is easy, come on, pick it yourself."

Looking at the handful of tickets in Gao Zhendong's hand, Sha Zhu's eyes widened, but he was not greedy. He picked two bicycle tickets, two watch tickets and one sewing machine ticket and stopped.

It's a favor that Gao Zhendong is willing to help, but if he takes a bunch of tickets to resell without caring whether he can use them or not, then things will go wrong.

He couldn't even handle these five tickets, and he had to save up for two months to buy them all. He also knew that Gao Zhendong must have cash on hand, but he couldn't just take advantage of one person. He had already shown great kindness by buying so many tickets, and it would be a bit too much for him to borrow money from him. He didn't want to lend his money unless it was absolutely necessary.

"Don't you want some cloth coupons or something? Not to mention you two, you need to get new ones for your sister and her kids, right? Oh, and for Old Mrs. Jia." In a case like Sha Zhu's, you really can't be careless at all. You have to take care of both ends of the hand, otherwise you will be remembered for the rest of your life if you are not careful.

"Hiss~~~~~~Yeah, you've thought this matter through carefully." Sha Zhu felt that Gao Zhendong was knowledgeable, as he himself had not considered these things.

"But I don't know how much cloth you need. Wait for me to discuss this with Sister Qin. I'll come to you for it after the quantity is confirmed." Sha Zhu is still the same, not greedy.

"Okay, fine." Gao Zhendong had no intention of using the ticket to attack anyone.

The two discussed for a long time. To be honest, Gao Zhendong didn't think so much about his own marriage. When he got married, he just let it go.

The two chatted for an hour or two, but in fact they didn't say much. All they heard was Sha Zhu expressing his feelings. As an old bachelor born in 1935, it is normal for him to be excited about getting married soon.

When Sha Zhu left, he was so excited that he said, "Zhen...Zhendong, tomorrow you and I will go find...find an uncle."

Gao Zhendong readily agreed and sent the brother back to the Intermediate Court. To be honest, it was okay if it was Gao Zhendong who sent him back. If it was someone else, He Yushui would probably start scolding him.

However, the next day, Gao Zhendong finally failed to go to see Yi Zhonghai with Sha Zhu. The next day, he received a call asking him to go to Chunlei Factory.

Gao Zhendong guessed that it was about the laser-guided bomb. Apart from this, there was nothing else at the Chunlei Factory that had anything to do with him. As for the long-range dispenser, small-scale production and trial use had already begun, and it was basically done.

There is no other way. If there is a problem with this thing, we really have to go to the scene. We can't fly a plane with a bomb to Beijing and drop it. That would be too much fun.

Gao Zhendong first called his father-in-law and made arrangements for Lou Xiao'e. In fact, there was nothing to worry about, as Lou Xiao'e was very safe over there. Now the old couple were really holding her in their hands for fear that she would fly away, and holding her in their mouths for fear that she would melt.

Then he made a special call to the cafeteria and told Sha Zhu that he could either wait for a few days or go first. Sha Zhu chose to wait for a few days without hesitation. He was nervous about going first.

Gao Zhendong took a plane directly with his men. It was very convenient for the Defense Work Committee to arrange a plane along the way. Although he could not reach the destination, he could save a lot of travel time.

It was still the flying tractor with super safety but poor comfort. I wonder if the National Defense Committee also knew about the safety of this aircraft and was very confident that they specially arranged this thing for him. Anyway, Gao Zhendong had never taken a plane of any other model. It was amazing to think about it. Chunlei Factory was not very far from Beijing, but the flying tractor was slow, so it took some time to fly there. After getting off the plane, he took a car for more than an hour to get to the location of Chunlei Factory.

Chief Engineer Zhang from Chunlei Factory was waiting at the factory gate early. Judging from the pile of melon seed shells in front of him, he should have brought most of his people here since the car that picked them up at the airport left.

"Mr. Gao, you are finally here. Welcome. Let's go and eat first. You must have been very tired from the journey. It's almost time. Let's eat something to fill our stomachs."

Gao Zhendong did not refuse. Firstly, it was indeed time for lunch. Secondly, some of his comrades had vomited their breakfast on the plane and needed to be replenished.

After dinner, Mr. Zhang brought Gao Zhendong to the conference room, where a large amount of materials had been prepared.

"Chief Engineer Gao, please take a look at our design first and familiarize yourself with the situation, then we can talk about other things." Mr. Zhang was not in a hurry to solve the problem.

Gao Zhendong opened the document in front of him and read it carefully.

Following Gao Zhendong's suggestion, Chunlei Factory did not choose the laser beam guidance method, as laser beam guidance has defects that are difficult to resolve when used in laser-guided bombs.

First, the guidance distance is short, and second, the laser beam basically requires that the launcher and the irradiator be the same. Otherwise, it is difficult for the missile to enter the range of the laser beam after launch, and beam guidance is out of the question.

These two factors basically determine that laser-guided bombs or airborne missiles are rarely guided by laser beams.

Following Gao Zhendong's suggestion, they chose laser semi-active guidance. The principle of this thing is actually the same as radar semi-active, except that the guidance medium has changed from radar waves to laser. Anyway, they are all electromagnetic waves.

Compared with radar, laser has the inherent characteristics of precise guidance due to its excellent monochromaticity and directionality. Under the premise of suitable weather conditions, the hit rate is very high.

Gao Zhendong watched the show from beginning to end and felt that it was all quite normal.

"Mr. Zhang, what problem are you facing now?"

Mr. Zhang took out a test record and said, "Mr. Gao, take a look at this first."

Gao Zhendong took a closer look and said, "It's pretty good. The hit rate is over 85%. And it also has good anti-interference performance against light rain and fog."

Judging from this test record alone, it can be said that the Chunlei Factory has basically achieved the goal of developing laser-guided bombs. The universal guidance head they developed, combined with tail fins and control surfaces of different sizes, can be installed on bombs of various calibers, up to 1000 kilograms.

The tail wing is stationary, and the one responsible for turning the bomb is the front half of the kit, the front control wing surface connected to the seeker. The advantage of this is that it greatly simplifies the design of the kit, and the tail wing part basically does not require much thought, and it is even completely separated from the front half.

For some bombs where the tail already provides sufficient stability, it is even possible to install only the head guidance and control system without moving the tail.

The test records also show that the efforts of the Chunlei Factory were effective. The bomb had a high hit rate, over 85%. Moreover, this hit meant directly hitting the bull's eye within a few meters, rather than a large target area. This is a hit rate and accuracy that ordinary bombs cannot achieve even with dive bombing technology.

That’s why Gao Zhendong said that they did a good job.

Mr. Zhang nodded. "If we talk about the effect of a single strike, it is true that under your guidance, we have achieved good results, but we have now encountered a new problem."

After saying that, he took out another test record.

"General Gao, look, this is the result of our simultaneous strike test with multiple ammunition. It's not very ideal. This strike method was proposed by our comrades in the Air Force and was not included in the original research plan."

Gao Zhendong looked at the requirements and couldn't say that there was something wrong with the Air Force. For some solid targets, in order to complete the strike in the shortest possible time and reduce the time of exposure to enemy anti-aircraft fire, this method of using multiple ammunition to attack the target at the same time was indeed necessary.
