Siheyuan starts from a better life

Chapter 468, news from afar
"Mr. Jiang, don't worry, I will take care of the bullet issue."

"About how long." Jiang Yan asked.

"I'll go take care of it now and get it back in the afternoon." After saying this, Shen Chong hurriedly picked up his hat and bullet drawings and prepared to go out.

As soon as he reached the door, he stopped, turned to look at the two pistols on the table and spoke to Jiang Yan.

"Mr. Jiang, can you let me take away one of these guns? This will be more convincing."

Jiang Yan listened and waved his hand.

Seeing Jiang Yan's action, Shen Chong walked quickly to the table where the two pistols were placed, and picked one up. After picking it up, he shook it with his hand. After giving it a try, he walked out with a smile. Office door.

Seeing the military representative leaving, Jiang Yan was a little overwhelmed. This man was really hot-tempered, and he was still in the office!
The masters had all left, and Jiang Yan had no intention of staying here. He put away the remaining guns and took his secretary back to his office.

When Jiang Yancong came to the office, he took out a drawing from the drawer. This drawing was the holster of the gun.

Jiang Yan also designed two types of condoms, one for the waist and one for the strap. After taking it out, he arranged for his secretary to find someone to give birth to the baby while he was busy processing the documents.

At the Shengjing Aircraft Research Institute, a thousand kilometers away from Sijiu City, Jiang Sirui came to the director's office with an anxious mood.

"Comrade Jiang Sirui is here, sit down quickly, sit down quickly."

Seeing Director Zhou Wei's enthusiasm, Jiang Sirui was a little overwhelmed.But he still sat there.

After seeing Jiang Sirui sit down, Zhou Wei took the opportunity to sit on Jiang Sirui's right side.

"Comrade Jiang Sirui, your design of adding a wing knife to the aircraft has been approved today. I hope you will continue your efforts and strive to come up with a better design."

When Jiang Sirui heard the leader's words, his heart finally settled in his stomach.

In the past, my superiors had always emphasized that the craftsmanship standards of the Mao Xiong Country should be strictly adhered to for production. However, after my own calculations, adding wing blades to the wings would increase the stability a lot, so I submitted this design plan as soon as I got excited.I originally thought my boss would criticize me, but I never expected to be praised.This made him overjoyed.

It turns out that the project Jiang Sirui participated in was none other than my country's first supersonic fighter jet. It was also the fighter jet with the largest amount of equipment, the longest service time, and the most glorious results in the People's Liberation Army.

This fighter is copied from Mao Xiong’s MiG-19 fighter.Speaking of which, the origin of this fighter jet is quite bumpy.

This aircraft is a complete set of drawings, technology and materials transferred from Mao Xiong to my country for a fee.So our country purchased three models of MiG-19, including S, P, and PM types.

Not only has the imitation cycle been shortened from two years to half a year, but a rapid trial production policy that ignores production rules has also been proposed.The so-called rapid trial production means not waiting for the data to be collected, using self-made process equipment, substituting geotechnical equipment and earth parts, producing parts and tooling simultaneously, modifying process procedures at will, etc. The result has a great negative impact on aircraft trial manufacturing.

The lessons of ignoring objective laws are painful.Overestimating domestic technical strength, coupled with the withdrawal of experts from Mao Xiong, resulted in unprecedented setbacks in aircraft imitation.

During the development process, the technological equipment required for trial production was greatly reduced. The aircraft's technological equipment was only half of the normal, and the engine's technological equipment was only one-seventh of the normal. As a result, aircraft parts could not be interchanged for a long time.Because they did not pay attention to Mao Xiong's information, they even required technicians to prepare technical information themselves and changed the design at will, resulting in process procedures full of errors and omissions.The management of aircraft manufacturing is chaotic, and a large amount of materials are made into parts that do not meet the requirements at all. The phenomenon of parts out of tolerance is serious.

Production discipline was lax and there were too many remnants from aircraft assembly. As a result, the first aircraft had 1400 faults. A large amount of iron filings, sand, rubber, etc. appeared inside. The rubber parts were aging and needed to be replaced. The rivets were of poor quality and could only be replaced. Big rivets.

The engine factory also found 15000 problems with the aircraft engines. Some necessary processes were even omitted, making them unfit for use. During use, the life of the aircraft was shortened, the aircraft was not strong enough, the entire aircraft vibrated, the horizontal stabilizer vibrated, and the components were uncoordinated. Major problems such as the air intake rivets falling off.

When the superiors inspected the airport and saw this situation, they became furious and asked the factory to immediately stop production for rectification and restart the imitation.After learning from the experience, the institute decided to restart trial production, requiring that some products must be made from scratch, some in accordance with the process standards of the Bear Country.

In order to gain access to Mao Xiong's technical information as soon as possible, the state transferred a group of aircraft design talents from across the country to work at the Shengjing Aircraft Manufacturing Factory.

Jiang Sirui's group is mainly responsible for the research on airfoils, and has made great progress so far.

Not long ago, a large number of high-alloys arrived at the research institute. This batch of alloys is not only lighter than the alloys imported from the Bear Country, but its hardness is three points harder than the alloys from the Bear Country. That is why everything is different. It was necessary to tear it down and start over again, which is why Jiang Sirui came up with the plan of adding wing knives to the wings.

In fact, Jiang Yan told her this plan when she was chatting with Jiang Yan in Sijiucheng.

I originally thought that Jiang Yan was just talking, but through his own calculations, he found that the stability of the aircraft has indeed increased a lot after the wing blades were added to it.

Jiang Sirui thought about it for a moment, then said: "It was not my first idea to add wing blades to the aircraft."

"Who came up with it?" The director said this with a bit of severity.

This aircraft was still a highly confidential matter, but suddenly an outsider knew about it. He felt that this was a bit of a leak.

Jiang Sirui regretted it when he said this. If he didn't explain it, it might be treated as a leak.

So Jiang Sirui quickly explained: "My husband, Comrade Jiang Yan, once studied in the Bear Country and saw the MiG-19 aircraft in the Bear Country. When chatting with him before, he said that this aircraft The wing has some flaws, and adding a wing blade will solve some problems."

When Zhou Wei heard Jiang Yan's name, he finally felt relieved.

"I didn't expect Comrade Jiang Yan to be your husband." The voice was slightly surprised.

"Director Zhou, you know my husband." Jiang Sirui said a little surprised.

We know Zhou Wei very well. A year ago, there was a problem with the equipment in his research institute and no one could solve it. So he found Jiang Yan. He not only repaired the equipment for him, but also upgraded it.

Moreover, he also led the technicians of the entire institute to repair all the equipment in the institute. Not only did he repair it, he also brought out a group of technicians. Zhou Wei was quite impressed with Jiang Yan's skills and character. Satisfied, the two became good friends.

There is also the arrival of this batch of special alloys, the inventor of which is Jiang Yan.

Therefore, when Jiang Sirui said Jiang Yan's name, he knew that there was no leakage of secrets. Jiang Sirui's confidentiality qualifications were higher than his own.

"I know you. I didn't expect you to be his wife. From now on, don't call me director, call me brother. Your husband and I are good friends. If you have any difficulties here in the future, remember to come to me."

At this time, Jiang Sirui said hello in one head. Why did his husband still know the director here? He had never heard of him!
After the two exchanged some pleasantries, Jiang Sirui left the director's office with greetings. When she was going back, she wrote a letter to ask Jiang Yan to find out what was going on.

After Jiang Sirui left, Zhou Wei sat there and smoked a cigarette. Before, he had only known that Jiang Yan was doing research on mechanical equipment, but he didn't expect that he was also doing research on aircraft. This kid hid it too deeply.

Thinking of this, Zhou Wei picked up the phone and dialed a number. After a while, he hung up the phone happily, but he smiled like a fox who stole a chicken.
