Siheyuan starts from a good life

After the meeting, Jiang Yan was just about to leave when he was stopped by Mr. Xu's secretary and took Jiang Yan to a conference room on the third floor.

There were two security guards with guns standing guard at the door of the conference room. The briefcase that Jiang Yan carried with him was taken over and Jiang Yan was told that the whole meeting was not allowed to be recorded.

This made Jiang Yan feel that this meeting was very unusual. With some curiosity, Jiang Yan walked into the conference room.

There were not many people in the conference room, less than twenty people. In addition to the main leaders of Shengjing Aircraft Factory, Director Tan of Shengjing Engine Factory was also sitting there.

Among the rest of the people, except Mr. Xu, Jiang Yan only knew two senior engineers from the aircraft factory, and Jiang Yan did not know anyone else.

At the beginning of the meeting, Director Ma of the Shengjing Aircraft Factory set the tone for today's emergency meeting: "Comrades, all information in today's meeting needs to be kept confidential. The materials can only be circulated, not recorded, and not taken away. "

"Now, Chief Engineer Xu will explain to you the basic information about these materials."

"Comrades, let's take a look at the information first."

As soon as Mr. Xu finished speaking, someone took some information and distributed it, and Jiang Yan was lucky enough to get one.

Jiang Yan quickly looked at the information in his hand, with a look of shock on his face.

This is part of the data of the Mao Xiongguo MiG-21, which later became the famous Zhan- aircraft of our flower growers.

After seeing this information, Jiang Yan thought about it and said, yes, our country has already begun to introduce this type of aircraft at this time.

Historically, my country began to become interested in the MiG-20 fighter jets of the Mao Xiong country in the late 50s, and planned to introduce MiG-21s from Mao Xiong. At that time, because the relationship between the two countries had already cracked, Mao Xiong did not want to provide this model of fighter jet to our flower growers.

However, with the changes in the international situation at that time, Mao Xiong needed my country's support at that time, so the two countries signed an agreement in 1961 to grant China the manufacturing license for the MiG-21F-13 aircraft and R-11F-300 engines, which were provided by Mao Xiong. Including a full set of production technical data, aircraft and engine bulk parts, as well as finished products and raw materials that were lacking in the country at the time.

But now most of these raw materials have been produced by Jiang Yan, and some of them are even better than those provided by Mao Xiong to our flower growers.

Calculate the time, if I remember correctly, in March this year, after more than 3 days of negotiations, our country’s personnel signed a production license for the MiG-13Ф aircraft equipped with K-21 missiles. , technical information and agreement on assistance to florists in the production of MiG-13Ф aircraft equipped with K-21 missiles.

协定规定毛熊国将在1961年8月至1962年10月期间将无偿地向种花家提供米格-21Ф-13型飞机（含p-11Ф-300型涡喷发动机和k-13型红外制导空空导弹）的全套生产图纸和技术资料。

It also provided some raw materials, blanks, finished products and accessories for 120 aircraft, engines, and missiles that the flower growers could not produce at that time.

同时还向我国提供一架样机、两台发动机以及飞机、发动机、导弹的部分散装组合件，整个协议共需支付给毛熊国的费用为人民币9，032万元。同时种花家空军还将直接购进12架米格-21Ф-13型飞机。

However, as relations between the two countries soured, the Bear Country did not fully implement the agreement. In fact, our country only obtained part of the technical data of the MiG-21, and the documents it received contained many errors.

Only a few prototypes are actually useful for the R&D and production of Zhan-7, which makes trial production difficult. However, our country later built the Z-7 prototype based on some information.

If there is an aircraft that has the most improved models, it is undoubtedly the Z-7 aircraft. There are countless versions in later generations. It is also the most important aircraft in our country. Until the time when Jiang Yan traveled through time, although our country's new fighter aircraft were emerging one after another, However, the veteran Zhan-7 aircraft has naturally not retired and is still protecting our country's blue skies.

Therefore, Jiang Yan was most impressed by this aircraft.

But what makes Jiang scratch his head is that his previous improvements to the Zhan-6 aircraft will probably have to be overthrown and restarted.

Because the aircraft that Jiang Yan improved is based on a single engine. The thrust rate of the single engine introduced by the Zhan-6 aircraft is not enough. Jiang Yan designed it to have a dual engine when designing it. Now, The newly introduced engine was more powerful, so Jiang Yan came up with his idea. However, the aircraft designed by Jiang Yan was also a derivative version of the historical Z-7 aircraft, so he was giving it back in disguise.

"Our superiors have asked us to set up a task force as soon as possible so that we can fully understand their technology as soon as possible and produce our own fighter jets."

"This time the task force is headed by Mr. Xu. Due to Comrade Jiang Yan's ability in researching the Xinzhan-6 aircraft, he is now the deputy team leader."

Hearing the news, Jiang Yan was completely confused and felt that he was done. He might not be able to go back in a short time.

This is because my country’s first Zhan-7 aircraft rolled off the production line around 64. It's only the end of August 61. If things go according to this situation, I will probably stay here for another three years. This is a business trip! I felt like I was being seconded, and the time was too long.

But now Jiang Yan is more worried about his daughter-in-law Jiang Sirui, who is newly pregnant and has joined the project again.

Entering this key project, he was probably so busy that there was no day or night. What should he do alone with a big belly?

Jiang Yan then thought that it would be better to apply for her to return to Sijiu City while his belly is not very big now. If there is no grandma and the others, he would feel relieved to have them around.

While Jiang Yan was scratching his head at the meeting, a train from Sijiucheng to Shengjing was slowly entering Shengjing Station.

"Grandma, how are you? Are you tired? Otherwise, let's find a place to rest first, and then go find the boss after we have rested." Xu Damao persuaded the old lady while helping her get off the train.

"Why are you so tired? You ate and slept all the way. Not to mention the bed on the train, which is quite comfortable. When you go back, ask Jiang Yan to book a train ticket like this for you. "

"Now that we have trains, they are very fast. I remember when I came to Shengjing with my father, it took a full month. We arrived in one day and one night. It was really fast." The old lady babbled while receiving Xu Damao's support. Got off the train.

After arranging the old lady, Xu Damao asked Lou Xiao'e to look at the old lady, then turned around and boarded the train again.

This time when they arrived, they brought a lot of things with them. There were several large bags, and they had everything to eat and drink. Most of these things were prepared by grandma for Jiang Sirui.

To be honest, this old lady is also quite a thief. Ever since she decided to go to Shengjing, the old lady has been shopping for national food stamps every day.

What he was thinking about was that he might not be back soon. His food supplies were in Sijiu City, and there was basically no need to prepare some national food stamps in Shengjing.

This old lady is a local snake. Many merchants and old neighbors will give the old lady a little face. The old lady just buys one or two taels, and a catty or two catties is exchanged for two hundred catties.

What he didn't know was that Xu Damao carried thousands of kilograms of national food stamps in his pocket. He had no choice but to do so because he was Lou Bancheng's son-in-law, so this was nothing to his father-in-law.

He Yuzhu also exchanged nearly a hundred kilograms of national food stamps. In these days, it is still necessary to carry more national food stamps when going out.

Carrying these large and small bags was too tiring. After leaving the station, Xu Damao found a few man-powered three-wheelers. With them dragging the luggage, he walked over according to the address given by Wang Honghai.
