Chapter 609 "Simple" Craftsmanship

Gao Zhendong had a "teachable" expression on his face, which almost made Lin Lianwei go crazy.

Seeing that Lin Lianwei was about to explode, Gao Zhendong quickly threw out a bait to block his mouth: "You have thought of the problem, but have you thought of a solution?"

"Ah, this..." This question stumped all the comrades in the Missile Research Institute, including Lin Lianwei. If they had this ability, then the Thunder-2 missile that Gao Zhendong saw in his previous life would not have been solved only after it became outdated.

"Use an infrared dual-color guidance head?" Lin Lianwei thought of the suggestion made by Gao Zhendong's own master, Mr. Lu, to solve the flame interference of terminal-sensitive projectiles.

As for advanced products such as thermal imagers, they can solve this problem, but the price and size of infrared surface-to-air missiles obviously cannot support this technology.

Gao Zhendong shook his head: "The spectrum of sunlight is very complete, and using infrared two-color is of little use. However, completeness is also a characteristic."

It denies an idea, but through this denial it provides a lead to an answer.

Simply put, the infrared characteristics of an aircraft have wavelengths that are also present in sunlight. It is very difficult to distinguish the infrared characteristics of an aircraft from sunlight through infrared sensors, to the point where it has no engineering significance.

After all, Lin Lianwei has been studying infrared sensors for a long time, and he has some experience with this kind of special electromagnetic wave sensors. As a graduate of China University of Political Science and Law, except for being incomparable with Gao Zhendong who is of super specifications, he is a well-known figure no matter where he is.

He frowned and muttered, "Complete...complete...two-color..."

After a long while, he raised his head and said, "Lao Gao, you mean ultraviolet?"

Gao Zhendong smiled and nodded: "Oh, yes, that's what I mean, a red and purple dual-color guidance head."

In fact, the so-called red-ultraviolet dual-color guidance head is more accurate. The reason is not that the ultraviolet characteristics can guide the missile to the target, but that the ultraviolet rays can prevent the missile from flying to the wrong target. This thing is used to resist interference and filter out false targets.

Sunlight contains a large amount of ultraviolet rays. It is these ultraviolet rays that are often used to supplement calcium and disinfect the body.

Gao Zhendong installed a red and purple dual-color sensor in the automatic fire extinguishing and explosion suppression system of the second-generation tank in order to use an ultraviolet head to lock the gas injection system to avoid misoperation under sunlight.

"Using ultraviolet light to distinguish the sun, the ability to resist solar interference is greatly enhanced. Moreover, this is also a very important auxiliary ability for head-on attacks."

"Can ultraviolet rays distinguish head-on attacks?" This was a big turn and Lin Lianwei obviously hadn't thought it through.

Gao Zhendong smiled: "No, it has nothing to do with the sensor detection capability, but with the tactics. If conditions permit, enemy aircraft always like to attack with their backs to the sun, otherwise they will also be affected by the sun. If infrared portable air-to-air bombs become popular, it will be even more so. If you want to fight head-on, you must try your best to solve the problem of enemy aircraft attacking from the direction of the sun!"

To put it simply, head-on enemy planes often come from the direction of the sun.

This reason is very powerful, so powerful that even the comrades in the Missile Research Institute feel ashamed of themselves. This reason has nothing to do with the missile's hard indicators, but it does exist in actual combat. If Gao Zhendong had not said it, with their current experience, they would never have thought of this.

In fact, there is one more thing Gao Zhendong didn’t mention - the reflection of sunlight by snow-capped mountains is also very strong. When fighting in a snowy mountain environment, the ability to distinguish sunlight is also very important.

This is too targeted and it’s not appropriate to talk about it here.

"Where do we get the UV sensor?" We are back to the old question: we don't have this thing.

Mr. Feng, who asked the question, looked at Gao Zhendong's smiling face and suddenly realized that the question was right!

What does this person in front of me do? I really don't know how capable he is. He does this and that, and he does them all very well.

But one thing is very clear - the materials!
The Lei Dian-1 did not use much of it - just the engine casing and propellant, but the Lei Dian-3 had it all over its body, especially the infrared seeker!

Since he can solve the infrared problem, then ultraviolet should be no problem, right?
As he expected, upon hearing this question, Gao Zhendong directly pointed them to a place.

"After the project is officially launched and work begins, I'll write you a note. You can ask the National Defense Committee for permission, and then go find a unit that is using a red-ultraviolet dual-color detector. You can't use the infrared part, but the ultraviolet part is just right for you."

It goes without saying that the reason why this unknown unit can use high-end products such as red and ultraviolet dual-color sensors is closely related to the young chief engineer in front of him.

Grassland Tractor Factory: It’s not very advanced, it’s all used for fire fighting.

Lin Lianwei happily kept this matter in mind. Following Lao Gao's lead, things would be safe!
For him, it was such a blessing that the first project of the subsystem he was responsible for happened to keep up with Gao Zhendong's project!
After seeing off his comrades from the Institute of Research, Gao Zhendong received a call from Lecturer Zhang from Beijing University of Technology, informing him that the tear gas had been officially launched.

Naturally, for such a small project, Gao Zhendong would not be required to personally attend the project establishment meeting. Lecturer Zhang could just write a report and that would be the end of it.

Lecturer Zhang chose the thermal dispersion smoke generator, a structure that was familiar to her and not difficult to use.

The only difficulty is the synthesis of tear gas. This call is for this purpose. Professor Gao said last time that we can just ask him when it is officially launched. Gao Zhendong put down the phone, wrote an encrypted email, and sent it to Lecturer Zhang. The synthesis of this thing is actually quite simple.

However, Gao Zhendong's understanding of the word "simple" was obviously different from that of the general public. The comrade who was responsible for cooperating with Lecturer Zhang to synthesize the tear gas widened his eyes when he saw Gao Zhendong's email.

"Teacher Zhang, is this craft real or fake?"

Lecturer Zhang didn't quite understand what he meant: "Engineer Huang, is there something wrong with this process?"

That's impossible. Professor Gao is from Beijing University of Technology. He is known for his reliability. He is a reliable person and his skills are also reliable.

"No problem, no problem. What I mean is that I'm afraid I can't achieve the final target. It's too high!"

Engineer Huang looked at the final process indicators and became a little worried about his own skills, mainly because the indicators seemed a bit high.

"The yield is greater than 95%, which is very rare." This means that with 100 kg of feed, more than 95 kg of product can be obtained. This is not a chemical reaction, it is a physical mixing, right?

Just pile several reactants together, stir them, and serve, right? Cooking is not as efficient as this, even stewing soup is not.

Not only this, other indicators also look extremely outrageous.

"The CS content of the product is 98%, the reactant residue is no more than 1%, and the product is 100% particles no larger than 30 mesh. It feels like synthesis, purification, crystallization, and crushing are all done at the same time."

Lecturer Zhang didn’t know how Mr. Huang felt, she only knew that she had found the right person.

The craftsmanship that could make an aging worker so amazed must be extraordinary. It sounds like this thing can be put directly into tear gas.

"Mr. Huang, please try your best. It should be fine. This process comes from an expert with very advanced technology, so its reliability should be guaranteed. Don't worry, even if it doesn't meet the above requirements, it is good enough for me."

In Gao Zhendong's case, it is hard to say that he is very famous, but it is almost certain that he is very profound.

Only someone like Lecturer Zhang, who is obsessed with academics, can say the second half of the sentence. It can be said to be comforting, but it doesn't seem to be the case.

"Well, I'll try my best. I can't let such good craftsmanship go to waste."

Mr. Huang doesn't care. The most important thing is to do a good job.
-
At night, somewhere in the suburbs of Beijing, a figure hurriedly ran into a room.

As soon as he entered the house, he took off his hat. The weather in April was not that cold, but his bluish scalp was still slightly steaming.

Holding a small flashlight, he carefully observed the various secret buttons he had left in the room. Only after confirming that they had not been touched did he feel slightly relieved.

Walking to a corner, he pushed open a cabinet and took out a notebook wrapped in oilcloth from the secret compartment on the ground.

This notebook is very strange. It is rolled up together with a grenade. The method is very clever. In a hurry, there is absolutely no way to separate the two things, at least within the few seconds after the grenade string is pulled.

He carefully put the notebook into his arms, then took out the pull ring of the grenade and tied it to a cloth button inside his clothes.

After testing the distance to ensure that he would not accidentally pull the ring with his various movements, he buttoned up his clothes. He wanted to die, but he didn't want to die inexplicably.

After doing this, the figure patted his chest, as if the heaviest stone in his heart had been put down.

Turning around, he began to pack up the other things in the secret compartment, some gold bars, some banknotes, and some blank papers, which seemed to be stamped with an official seal and should be blank letters of introduction.

For him, apart from the notebook, this blank letter of introduction was the most important thing, as it determined whether he could escape or not.

Without a letter of introduction, it means that he will not be able to obtain any normal supplies on his escape journey, nor can he take any long-distance transportation. It is simply a fantasy to want to escape by walking or hitchhiking for short distances.

The roads and bicycles these days are not suitable for people to ride.

If you can steal or rob when you have no money, then getting a letter of introduction is not so easy.

After putting away the letter of introduction, the figure put the gold bars and most of the large-denomination banknotes into the secret pockets of his clothes and trousers, leaving some small change and two large black tens in the outer pockets.

After doing all this, he groped in the dark in the house with the dim light of a flashlight to find water and food and started eating. The rest of the journey would surely be very difficult.
