Thank you Tianhai Xiangyun for your reward.

There are many things happening these days, so I have always been a single update, but Hulu promises that as long as the matter is done, I will definitely compensate for the updates I owe!

············

"Our factory is ahead. Leader, please prepare a letter of introduction and your work permit..." Yunguang Factory's factory buildings are brick-concrete structures. Compared with Su-style factories, they are less domineering and heavy, giving people a very depressing feeling.

When Liu Yijiu saw the dilapidated factory that caught his eye, he could not imagine that this factory had already built an active infrared night vision device and a complete machine industrialization base in the 1960s, setting a precedent for night vision instruments in China.

After handing over the certificate and letter of introduction to the armed forces for inspection and registration, the jeep entered the factory through the iron railing door.

Because the factory was built before liberation, even if it was expanded after the founding of the People's Republic of China, the roads of the factory appeared narrow because they were not well planned.

Before Wang Xinyue brought several people to an old three-story building with blue brick structure, he took several people into the office of the External Relations Office. Inside, an old man wearing a white-washed Zhongshan suit was frowning and looking at the documents in his hand.

"Director, I have brought back the comrades from Base 002..." Wang Xinyue said to the old man.

"Thank you a few comrades. After receiving the notice from our superiors, we are looking forward to your arrival..." The old man showed great enthusiasm when he saw Liu Yijiu and Chen Dashan. "My name is Xiao Siwei, the director of the External Liaison Department of Factory 298. He is responsible for receiving you..."

No one knows very well about Factory 298, and no one knows the organizational structure of this factory.

"Director Xiao, we are here for technical matters. I hope to get technical support from my brothers..." Liu Yijiu said in confusion.

The external relations department can manage technology?

"No problem, our external relations office is different from the external relations offices of other factories. We are responsible for everything that communicates with the outside world, including technology. Even the aid to build a brother factory is our business. The superior leaders have told us that our technicians are looking forward to it. Since we developed production technologies such as active night vision components in the early 1960s, there has been no technological breakthrough until now..." Xiao Siwei showed very high enthusiasm.

"This..." Liu Yijiu was very worried. Does this guy in front of him really understand technology?

In the past years, all research work was basically at a standstill. Only some projects such as nuclear submarines, intercontinental missiles, large aircraft, etc. that were launched in the early 1970s were moving forward with difficulty, and other factories were basically like that.

"No problem, Master Liu, let's not rush to rest and ask them the technical requirements. If you have any questions, let's find a way together and go back quickly. What do you think?" Chen Dashan was eager to get the sniper rifle now.

Along the way, I heard Liu Yijiu tell him the benefits of this sniper rifle and the usage of sniper rifle in the Soviet Patriotic War, the Korean War and the Vietnam War. Of course, there were also the situations where the Russians invaded Afghanistan and other large-scale wars, snipers became the main force in carrying out many important tactical tasks.

Other countries have been developing in this area for decades, and China has not yet started, so he has no choice but to be in a hurry!

Liu Yijiu did not object to this.

Sniper rifle is the first hurdle to prove his ability. Only when his ability is proved, some design plans he proposed in the base can be adopted. He is still very confident about this sniper rifle. As long as there is no problem with the scope.

"Everyone, I believe everyone knows the code of confidentiality. We come from the 9th Institute of Machinery and Machinery under the Fifth Machinery Department. I will not introduce the situation of the base here. This time, we mainly undertake the task of developing high-precision tactical rifles issued by the superior department. Time is tight and the task is heavy. We have completed the design work, but the aiming system is not our strength. Let us ask Liu Yijiu, deputy leader of the high-precision tactical rifle research project team, to introduce the situation to you..." Chen Dashan, as the person in charge of the base, did not introduce his identity.

Although the Ninth Academy Base is top secret, now that the superiors have already made up their minds to arrange scientific research tasks for them, collaboration is necessary.

If you don’t explain the situation clearly, how can you cooperate in the future?

"So young? Isn't it a joke?" Seeing that Liu Yijiu was so young, he was actually the deputy leader of the research project team, the technicians and managers of Factory 298 were immediately surprised.

There were many discussions.

Liu Yijiu didn't care about such a thing.

He is too young, and no one has succeeded in sniper rifle?

"Everyone, the high-precision tactical rifle we designed this time has an effective range of 1,000 meters and a maximum range of 1,500 meters. Just this requires that a scope must be installed on the rifle. Here is the appearance diagram of the sniper rifle we designed. We hope that your factory can help us develop a magnification of at least six times, with a viewing angle of about 6°. The appropriate distance between the sight mask and the shoulder is 190-200mm, which is determined to be 195mm; the distance between the watch door of the watch door is 245mm; the height of the cheek joint according to the human-machine ring design requirements is 50-75mm. In order to avoid excessive height when using the scope, so that the entire gun centroid is close to the axis of the barrel, our design requirements are 51mm; the height of the cheek joint of the 8-digit gauge is 50-53mm..."

Everyone did not expect that Liu Yijiu came up and had such a series of technical requirements.

This shocked all the technical people.

Although these seem to have little to do with their work, they know that the other party proposed these parameters limiting their design of the scope's appearance structure. They are truly cooperative and collaborative!

"In addition, our design idea is to hope that this sniper rifle can operate all-weather, so we hope that active infrared optical systems can be added when designing. In addition, in order to make the rifle reach the highest power, we hope that the scope can accurately measure the distance and orientation of the target within the maximum range..." Liu Yijiu's requirements are the upgraded version of his scope equipped with the 85 sniper rifle.

Originally, the domestically produced Type 79 sniper rifle was a copy of the Soviet SVD seized on the Vietnam battlefield. Due to domestic technical conditions and quality system problems, the quality of the four-fold scope is very poor, and the design did not consider how the gun and scope were combined, which made Type 79 very criticized.

Even the eighty-five styles that were improved by the seventy-nine styles still have many flaws...

Liu Yijiu needs to minimize these defects from the beginning.

"Comrade Liu, although we created the 62-type telescope more than ten years ago, the scope is different from the telescope. With such many requirements, we..." A slightly fat middle-aged man with a low height and a little bald forehead said to Liu Yijiu.

At the beginning, they guessed that this young man with great background was a big background. Just by hearing these words, they confirmed that he really had a big background, but this background was completely different from what they thought.

"Xiao Xue, what's the matter? Have you forgotten the difficulties we had in solving the Type 62 telescope? We have not made any technological progress in many years? As the first optical instrument factory in China, we now have nothing to do with the ground aiming system of the army. After so many years of idleness, do you want to continue? Do you give this project to other factories? If you have difficulties, you have to go on, and if you have no difficulties, you have to go on! Will our 298 factory care about the technical difficulty?" Regarding this matter, Cao Jingui, a thin factory manager in his sixties, slapped the table and said.

"Don't care!" Perhaps it was because Cao Jingui was well-managed, or perhaps it was because many people came from the army. When he said this, everyone answered firmly! This voice made Liu Yijiu see hope.

"Director Cao, are you willing to assist us in this project?" Liu Yijiu asked the old man very seriously.

If not, they can find Factory 358. Although it is built later, the technicians and equipment are all from Factory 298.

"Of course I'm willing. Comrade Xiao Liu, we have recorded your requests. Starting today, we will work hard to solve the problems. How much time have you left for us?" There must be time for these projects.

As for research funds, they don't need to consider them.

"At most two months!" Chen Dashan also knew that these studies could not be completed in a short period of time, and there were more than two months left for the Spring Festival. He hoped to get a new gun before the New Year! Then use this to fight rabbits and add vegetables, that's right!

"This..." Cao Jingui was a little embarrassed.

"Is there any problem?" Others don't know Chen Dashan's identity, but Cao Jingui, who also came from the army, could not have known it.

"No problem, let's take action as a mountain!" Cao Jingui said, patting his chest.

Some technical discussions were conducted, mainly because Liu Yijiu explained their detailed requirements for this scope, and then the technicians of Factory 298 raised the difficulties in it, and then the technicians of 298 discussed it. Within just a few hours, they came up with a preliminary plan.

In order to improve the defect that the 79/85 sniper rifle and scope cannot be well combined, Liu Yijiu made special modifications when designing this sniper rifle to rush into bamboo shoots. The front handle was removed directly by him, and it was changed to a mechanical sight that could be turned over.

Factory 298 has experience in researching the 62 telescope, it is relatively easy to meet Liu Yijiu's requirements in terms of sniper lenses.

"Director Cao, I hope you can take out the initial samples as soon as possible. At the beginning, there is no problem with the design. As long as there is a sample, you can completely modify the design while experimenting. This is what the superior leader means..." Chen Dashan was worried that he would not seize the time here, so he learned a lot from Liu Yijiu on the way, and he did not reveal the situation here.

As Liu Yijiu said, he raised the wind deviation, height, and magnification to the other party.

However, no one in the 298 factory dares to guarantee the adjustable multiplier, so they can only do fixed multiplier first...
Chapter completed!
