Chapter 615: Useful things are usually good looking (first two chapters, and one more chapter in the evening)
Gao Zhendong stood by the window, watching Sha Zhu and his gang wearing red flowers and walking by on the road below, beating drums and gongs. Like everyone else, he stood by the window and applauded enthusiastically.

After the parade passed, he turned back and looked at the pile of drawings on his desk.

The drawing looks similar to the mask of CPU and RAM. This is a math coprocessor, which is the result of Gao Zhendong's ICization of 32-bit hardware single-cycle multiplier.

The drawings have not been completed yet, but everyone has already used the hardware multiplication circuit board assembled with logic circuit chips. The time for this matter is not very urgent for him.

He sat down and continued his work.

At this time, the phone rang. He picked up the phone and found that it was the comrade who was working on the Zhengxian-1 anti-ship missile.

"Hello, Advisor Gao. We have received a mission to launch an air-to-air anti-ship missile. I have some questions for you. I wonder if you have time."

Gao Zhendong then remembered that he had mentioned air-launched anti-ship missiles when discussing air force equipment earlier. The comrades from the Air Equipment Bureau must have started this matter and found them.

"Yes, you can come anytime." Gao Zhendong said.

"That's great. We've already arrived in the capital and will come visit you soon."

It has already arrived?

Before the afternoon, Gao Zhendong met Engineer Qi, Su Weihua, and their chief model designer Mr. Li in his office.

They got down to business quickly; after all, they were here to do business.

"Advisor Gao, this is our preliminary plan. Please take a look at it first."

Gao Zhendong took it and took a look, and found that the overall plan was a smaller version of Zhengxian-1.

It has the shape of a small airplane, but because it is an air-launched missile, it does not have boosters, liquid engines, active radar guidance, or shaped-charge blasting warhead.

Seeing Gao Zhendong frowning, Mr. Li smiled and said, "Counselor Gao, is there a problem?"

Gao Zhendong put down the information in his hand and said, "Boss Li, is the liquid bullet not suitable?"

"We have considered this, but we have no experience with solid bullets."

"I remember that I provided a solid propellant to the Institute of Guidance Research. If we modify the formula, it can be used here."

"The main reason is that the changes are too big. As a result, the experience gained from No. 1 will be useless."

Gao Zhendong smiled: "Zhengxian-1 is for attacking large ships, and this one is for attacking small and medium-sized ships. The aerodynamic layout experience of Zhengxian-1 is not very useful. Moreover, the aerodynamic layout and fuel form of Zhengxian-1 are a bit outdated. If this plan is submitted, the Air Equipment Bureau will probably not accept it."

Liquid fuel is not a problem, but liquid rocket engines are a bit tricky, unless there is a small turbofan or turbojet engine of 500kg class. That thing is fuel-efficient, can fly far, and is lighter in weight.

However, Gao Zhendong did not have this intention, mainly because there was no such engine and it was unlikely to be produced in a short time.

Moreover, the solid rocket engine, which is about the same size as the previous Yingji-8, can reach a range of about 40-80 kilometers, which is enough for the current distance. If it is farther, the system's guidance system will not be able to keep up.

"So what do you mean, Counselor Gao?"

"I suggest using a solid rocket engine, a cylindrical body, and 4 cross-shaped wings at the front and 4 at the rear. Although air launch does not require folding wings and boosters, it is still recommended to consider this first."

The reason why Gao Zhendong particularly emphasized the front and rear cross-shaped wings was that he was afraid that these comrades would get carried away and come up with something weird like the ten-X-shaped wings that they had seen on air defense missiles in their previous lives.

"As for the weight, it's best to be below 750kg. As for the size..." Gao Zhendong basically copied the data of the air-launched version of the Y-81 from his previous life.

The ship-based version of the Y-8 anti-ship missile weighs more than 800 kilograms, but the air-launched version is lighter because it has no booster.

Therefore, Gao Zhendong's requirement to control it below 750kg is basically reliable. In this way, even with a payload of 1.5 tons, two bombs can be carried, posing a great threat to enemy ships.

The comrades from the Institute of Guidance and Research looked at Gao Zhendong's request and felt that it was a bit difficult and small.

"Advisor Gao, with such a thin bullet, the effect of the shaped charge blast may not be very good." The power of the shaped charge blast is directly linked to the caliber. If the diameter of the Zhengxian-1 is large enough to hold a powerful enough warhead, then the diameter of Advisor Gao's bullet is more difficult to deal with.

Gao Zhendong shook his head: "We don't need shaped charge blasting. We use semi-armor-piercing warheads. Small and medium-sized ships are not very good at defending against such warheads."

With the gradual disappearance of giant ships and cannons and the popularization of missile weapons, basically most small and medium-sized ships are fragile.

A semi-armor-piercing warhead may not be able to penetrate the main armor belt of a battleship, but it is not meant to attack large ships.

When it comes to dealing with large ships, the Russians are more direct and just send out Little Ivan.

The Russians really love Ivan. They use Ivan to build a reservoir, Ivan to open a road, and Ivan to prevent missiles...

"Well, semi-armor-piercing warhead, what about the seeker?" "Still use a single-pulse radar seeker."

"Advisor, given the diameter of this missile, wouldn't it be very effective if it used a seeker?"

"This is not a big problem. Some people working on radar are working on radar clutter removal technology, and other radar-related technologies are also being developed. I think we can handle it."

Mr. Li and his team didn't know how Gao Zhendong knew so much about radar, nor did they want to know. At least it was good enough that they could make a new radar.

"Advisor, then the range should still be based on the 1 of the first-level -50?"

Gao Zhendong shook his head and said, "It should be bigger, maybe 80. The ZX-1 can only hit targets 50 kilometers away because the radar on warships can only see that far, but air-launched aircraft don't have that problem. My suggestion is to try to push the range to the limit of the radar's performance."

"80 kilometers? Can the airborne radar support that?"

Gao Zhendong smiled and said, "Boss Li, this is going to be mounted on a plane of the size of the Z-5. The nose of that plane has a lot of space, so it has enough potential."

Mr. Li then remembered that this matter was mentioned in the proposal submitted to them by the Air Equipment Bureau. There is enough space in the nose of the B-5 to install a radar.

"Yes, yes, yes, look at my memory. But is it necessary to fold the wings for air-launch?" Gao Zhendong just mentioned the folding wings.

"An air-launched missile doesn't need to be folded, but I suggest you consider it early. If an air-launched missile is really developed and its performance is good enough, it wouldn't be strange to have one missile for multiple uses."

Mr. Li then remembered the reason why Gao Zhendong emphasized the size. In addition to air-launch, he even wanted to install it on missile boats and warships.

He looked at the sketch he had drawn based on Gao Zhendong's description, and the more he looked at it, the more he liked it: "Counselor Gao, you know what, the more I look at this missile, the better it looks."

Gao Zhendong smiled and said, “Good design usually has some aesthetics in it.”

—Except John Bull’s.

Mr. Li was moved: "Hey, what Mr. Gao said is interesting. Yes, it's interesting."

Hi, I copied this too.

General Li looked at the layout of the new missile and said, "Advisor Gao, everything else is easy. We have experience with the missile-borne computer and guidance system, and the semi-armor-piercing warhead is not too difficult to design. The only thing we don't have experience with is the solid rocket engine."

Gao Zhendong smiled and said, "As for the solid rocket engine, you can first communicate with the comrades in the Institute of Missile Research who are working on air-to-air missiles. Although their missiles are much smaller than this one, they still have some experience in solid rocket engines."

However, Mr. Li is obviously very clear about the strength of the Institute of Guidance and Research: "Well, I will go to them to take a look first. However, it is okay to improve the old ones, but if it comes to making new ones, I think their theories are still not perfect."

Gao Zhendong smiled and said, "If you have any questions, you can come to me after you start the specific design work. I have done a little research in this area."

He hasn't finished using the book on solid rocket engines that he won before, and there is still a lot of potential for him to explore.

When General Manager Li, Engineer Qi, Su Weihua and others heard what Gao Zhendong said and looked at the environment they were in, they even felt a little unreal.

"Okay, Mr. Gao, let's go back and revise the plan first, and report it to the Defense Work Committee and the Air Equipment Bureau for them to take a look. We'll come back to bother you when we start working on the relevant designs."

Anyway, at least we have found a possible way.

Gao Zhendong was working when several comrades from the Third Factory came to see him.

Director Yan of the Third Factory brought along several senior masters including Yi Zhonghai. What they were holding in their hands was a part of a round metal shell.

There are several wires connected to the part, and there is an axis extending out from the center of the front.

This is an industrial photoelectric encoder developed by the Guangyang Factory. Different from the one used in tanks, this one strikes a balance between cost, performance, and reliability, and can be used on a large scale.

Director Yan's face was full of joy: "Chief Engineer Gao, after we old comrades got this new equipment, we thought about it for a long time and have some ideas that we want to report to you."

This thing was obtained by Gao Zhendong to improve the automation level of the lithography machine. It can be said that this thing was made just for the lithography machine.

But in the eyes of these old masters, this dish of vinegar is naturally more useful than just that.

No matter how to do it, Gao Zhendong is good, but no matter how to use it, he can't compare with these comrades.

He quickly asked the old comrades to sit down and speak slowly.

"Chief Engineer Gao, after we got this thing, we thought about it for a long time and felt that it was really good. We thought about it for a long time, and with the current technology of the lithography machine workpiece stage and this photoelectric encoder, if we work harder, maybe we can make our machine tools better."

Gao Zhendong knew that the motion accuracy of the servo system of the worktable had reached several microns. Since they could make the silicon wafer worktable for the lithography machine, they could make other things not far from this.
