What Hu Wenhai said is actually the "reflective scope" of later generations, which is commonly known as the red dot scope and the fast scope.

It can be fixed on the aiming line of the gun, and even replaces the past three-point and one-line mechanical sights. It has the advantage of fast aiming and shooting quickly, and it is possible to form a straight line between the eyes and sights. What you see is what you get.

Since the mid-1990s, the US military has equipped this type of reflective red dot sight on a large scale. Even its magnification version is part of the ACR program, the advanced combat rifle of the United States. Other countries in the world, and even China, have introduced this technology one after another to equip conventional armies, even rapid response and special forces.

By the 21st century, the global market of red dot sights can even reach a scale of 10 billion US dollars. But of course, this thing is mainly purchased by military forces from various countries, leaving little profit margin for private enterprises. But even so, it is still a touching market.

There are two difficulties in manufacturing a reflective scope. One is its sight lens, which directly determines its aiming accuracy. The other is its lens coating, which can reflect light sources into people's eyes.

Hu Wenhai doesn't need to worry about the manufacturing of sight lenses. As the same goes, who told me that we had a Level 8 technician to touch Mr. Hu Shiwu? The mold used for lens processing is absolutely no problem if it is opened by him. The problem of reflective coating is better solved. It is the same as the material of automotive head-up displays in later generations, mainly using silicon monoxide. The refractive index of this material is 1.98, which is much greater than the refractive index of ordinary glass.

In this way, after several light interferences, you can obtain virtual image light spots from infinite distances.

However, whether it is HUD refractive technology, silicon monoxide material, or reflective lenses, all of them are! No! Yes! What! High technology!

This is what Hu Wenhai valued the most. Later generations had patent restrictions, so the price of red dot sights would remain high. Otherwise, a Chinese counterfeit factory would be eyeing them, and there were no toys on TB that were sold without bargain prices. Even in China in the 1980s, these materials were ready-made. As long as raw materials could be purchased, products with reasonable quality could be produced.

To put it bluntly, the red dot sight is just a layer of window paper. The principle is not much different from the HUD on the fighter. It’s just that in the subconscious mind, the high-tech used on the fighter is not enough to use the rifle.

Hu Wenhai's father Hu Jiefang is the director of the military factory, and the 64th Institute, as an optoelectronics research institute, has never done military projects. Even if Bai Shi does not understand military affairs, he always understands this simple truth at once.

After all, the aiming method of two points forming a line is definitely better than that of three points forming a line, and the market here is unquestionable.

The sound of the clanging train wheels pressing over the rails sounded regularly. In this green-skinned tank truck with the style of the 1980s, Hu Wenhai was bored and reading a book.

"Pippilu and Luxixi? Why do you see this?" Si Guxin looked at the cover of the book in Hu Wenhai's hand in surprise. A silly boy wearing overalls was scratching his head. If you don't say the content, at least the design of this cover is really a bit young.

Hu Wenhai was not embarrassed at all, and smiled and shook the book, saying, "Grandpa Si, don't underestimate Zheng Yuanjie. Although he wrote a fairy tale, he is definitely more thoughtful than 90% of Chinese literary writers. To be honest, this thing is a pity to show to children with no social experience. It's better for adults to receive education."

Hu Wenhai was talking when he suddenly heard the radio in the carriage start to broadcast. The two of them calmed down and listened carefully. It turned out that it was Shengjing Station, the provincial capital of Bohai Province, was about to arrive.

When Hu Wenhai and Si Guxin heard that the destination was about to arrive, there was no conversation. The two of them put away all the food and books they ate along the way, and then took the salute off the luggage rack early.

In 2015, it took only two or three hours to get from Xiucheng to Shengjing, and in the 1980s, the journey would take more than eight hours. After so long, it was not a good experience for Hu Wenhai, who had never suffered much, and Si Guxin, who was already a little older, was not very beautiful.

So as soon as the train stopped, the two of them had already picked up their salutes and walked out quickly along the flow of people.

As a heavy industrial city, Shengjing can even be said without hesitation that the cradle of the industry in New China is here. Even in the 1980s, the population of Shengjing city had reached five or six million. With so many people gathered in a planned economic industrial city, you can imagine how many factories this city has.

As soon as Hu Wenhai and Si Guxin came out of the train station, they saw someone waiting at the exit with signs. A thin middle-aged man with two beards, hair looks like a bird's nest, and wearing a fat navy blue suit, leaning lazily under a telephone pole.

"Xiao Jiang, we are here!" Si Guxin waved his hand and shouted loudly at the middle-aged man.

"Hello, Principal Si, Director Wang asked me to pick you up." Xiao Jiang reluctantly took the salute from the newbie of Si Gu. The old man was half-filled, carrying a canvas bag of at least one meter long, and many people were aiming here.

Xiao Jiang took the two of them for a while, passed through the square in front of the railway station, and arrived at a dilapidated van on the side of the road. It looked like the type of "no sound except the horn, but no sound everywhere". But even so, in this era of bicycles everywhere, it stands out.

"Is this your child? Alas, why haven't you heard you mention it?" Xiao Jiang jumped into the car skillfully, twisted the key a few times before starting the car. The van made a grunting sound, panting and moving forward with difficulty.

"If my grandson has one-tenth of Wen Hai's ability, I can wake up laughing when I sleep!" Si Guxin waved his hand and said with a smile: "This is the grandson of a friend of mine. This time I brought him to 601 to discuss cooperation."

"I'm so old to bring it out to see the world? Why, have you been to college?" Xiao Jiang's words exuded a sense of pride and pride, as if he hadn't gone to college, he could not even enter the 601 gate.

"This year's senior year, going to college is probably no problem. Right?" Si Guxin turned his head and looked at Hu Wenhai and asked, "By the way, Wenhai, I haven't asked you which university you are going to take next year?"

"I haven't thought about it yet, but I think it's probably either the National Defense Technology University or the University of Science and Technology of China."

"Hey, aren't you going to take the Tsinghua University and Peking University?" Si Guxin was stunned and asked subconsciously.

"Haha, the President of the Department said that Tsinghua University and Peking University are his family. Can you pass the exam if you want to? "Xiao Jiang shook his head and said in disbelief: "Don't talk about Tsinghua University and Peking University, even the National Defense University and the University of Science and Technology of China, it would be great to pass the exam!"

"Haha, it's hard to say about other children, but if it's Wenhai, I think it's okay for domestic universities to go to any of them!"

"Principal Si... you really value him." Xiao Jiang smiled unquestionably and turned around and drove there intently.

I had no words all the way, and the van was set up in Shengjing and walked through the streets and alleys. It took me a full hour to drive, and then I arrived at a gate.

Hu Wenhai jumped out of the car and saw the inconspicuous plaque hanging on the edge of the door, with black paint on it saying: Shengjing Aircraft Design Institute.

This is Chen Huoy...

In the future, there will be many snoring in the military aggression around this compound on the Internet. The name Chen Huoyi is always on the verge of Huoyi, but this does not mean that he has any prejudice against "Chen Huoyi".

In any case, if Sukhoi's technology can defend the sky of the motherland, what does it matter if he follows the Soviet Union's technical route? From Su27 to J-11, China has completed the transformation from the Land Defense Force to the Strategic Air Force. Shen Hokhoi has made great contributions and has made indelible contributions.

After all, it is just that everyone has always had too high expectations for it, so that in the competition for the fourth-generation aircraft, Shen Huoyi was angry that he did not fight and hated him for nothing. But we should also think about it, sometimes manpower is poor, which research institute can fight on both sides while developing third-generation heavy aircraft?

After all, this is a holy place for Chinese fighter jet development, and a place where a group of people who have made great contributions to the country will throw their youth and passion.

Standing in front of this door, Hu Wenhai unconsciously looked solemn.

After a tedious verification process in front of the door, Hu Wenhai and Si Guxin followed Xiao Jiang and finally walked into 601.

The space inside the gate was unexpectedly large. After more than ten minutes of sitting in Xiao Jiang's van, Hu Wenhai and Si Guxin were only able to really get to the place.

This is a two-story, square building with some flowers, plants and trees in front of the building, but it is obviously not very careful to take care of. The vigorous growth of grass and trees in midsummer makes the place feel a little messy.

There was already someone waiting there at the entrance of the building early. A middle-aged and elderly man in a white coat and half-white hair hurriedly walked down the steps and grabbed Si Guxin's hand without saying a word.

"Brother Si, it's been a long time since we met!"

"It's been more than two years, I miss me so much!"

The two men with white hair hugged each other excitedly, greeted each other, and then they had time to introduce Hu Wenhai. Si Guxin pointed to the man in a white coat and said, "This is your grandfather Wang, the director of a certain laboratory. I won't tell you about your specific identity. You are not unfamiliar with confidentiality regulations."

After saying that, Si Guxin turned around and said to Director Wang: "Old Wang, this is what I told you, Hu Wenhai, the inventor of that small turbojet engine."
