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

At the door of the conference room, two security guards with guns stood guard, and Jiang Yan's briefcase was taken and told that Jiang Yan was not allowed to record the whole meeting.

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

There were not many people in the conference room, less than 20 people, in addition to the main leaders of the Shengjing Aircraft Factory, the director of the Shengjing Engine Factory, Tan was also sitting there.

For the rest of the people, except for Mr. Xu, Jiang Yan only knew two senior engineers from the aircraft factory, and Jiang Yan didn't know any of the others.

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

"Next, Chief Engineer Xu will explain to you the basic situation of these materials."

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

As soon as Mr. Xu's words fell, someone took some information and distributed it, and Jiang Yan was also fortunate to get a copy of the information.

Jiang Yan quickly glanced at the information in his hand, and his face was shocked.

This is part of the information of the Mao Bear National MiG-21, which is later part of the information of our famous Zhan 7 aircraft.

Seeing these materials, Jiang Yan thought about it for a while, yes, at this time, our country has begun to introduce this aircraft.

In the original history, at the end of the 50s of the 20th century, China began to become interested in the MiG-21 fighter of the Hairy Bear country, and planned to introduce the MiG-21 from the Maoxiong. At that time, due to the rift in the relationship between the two countries, Mao Xiong did not want to provide this type of fighter to our family.

However, with the changes in the international situation at that time, Mao Xiong needed the support of our country at that time, so in 1961, the two countries signed an agreement to grant China a manufacturing license for MiG-21F-13 aircraft and R-11F-300 engines.

However, now most of these raw materials have been made out by Jiang Yan, and even some of the materials are better than those provided by Mao Xiong to our flower growers.

In March of this year, after more than 20 days of negotiations, our personnel signed an agreement on granting the flower planters the right to produce MiG-21Ф aircraft with К-13 missiles, technical data, and assistance to the planters in the production of MiG-21Ф aircraft with К-13 missiles.

The agreement stipulates that between August 1961 and October 1962, the Hairy Bear State will provide the planters with a complete set of production drawings and technical data for the MiG-21Ф-13 aircraft (including the Р-11Ф-300 turbojet engine and the К-13 infrared-guided air-to-air missile) free of charge.

In addition, 120 planes of raw materials, blanks, finished products and accessories needed for aircraft, engines, and missiles that could not be produced by the flower growers at that time were also provided for a fee.

At the same time, it also provided China with a prototype, two engines, and some bulk assemblies of aircraft, engines, and missiles, and the total cost of the entire agreement to be paid to Mao Xiongguo was RMB 90.32 million. At the same time, the Huajia Air Force will also directly purchase 12 MiG-21Ф-13 aircraft.

However, with the bad relations between the two countries, Mao Xiong did not fully fulfill the agreement, in fact, China only obtained a part of the technical information of the MiG-21, and there were many errors in the documents in hand.

In fact, there are only a few prototypes that are useful for the development and production of the Zhan-7, which brings difficulties to the trial production. However, later China still built a prototype of the Zhan-7 based on some information.

If you say which aircraft has the most improved models, it is undoubtedly the Zhan-7 aircraft, the later versions are countless, and it is also the most powerful aircraft in our country, until the time when Jiang Yan crossed, although China's new fighters emerged in endlessly, but the Zhan-7 aircraft, a veteran, naturally did not retire, and still protected the blue sky of our country.

Therefore, Jiang Yan has the deepest impression of this aircraft.

However, what made Jiang scratch his head was that his previous improvement of the Zhan-6 aircraft was estimated to be reversed.

Because, Jiang Yan's improved aircraft is based on a single engine to improve the aircraft, the single engine introduced by the battle-6 aircraft is not enough, Jiang Yan was designed as a double normal engine when it was designed, and now the power of the newly introduced engine is greater, because Jiang Yan started his idea, but this aircraft designed by Jiang Yan is also a derivative version of the historical war-7 aircraft, and he is also a disguised return to it.

"The superiors asked us to set up a team to attack the fortification as soon as possible, so that we could thoroughly understand their technology as soon as possible and produce our own fighters."

"This time, the attack team is headed by President Xu, and because of Comrade Jiang Yan's ability to research the Xinzhan-6 aircraft, he is now the deputy leader."

Hearing this news, Jiang Yan was completely blinded, and he felt that it was over, and he was afraid that he would not be able to go back in a short time.

This is because the first Battle-7 aircraft in our country rolled off the assembly line around 64. It's only the end of August 61, and if this situation is followed, it is estimated that I will stay here for another three years, which is a business trip! It felt like I was seconded, and it was a little too long.

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

Entering this key project, it is estimated that there is no day and night when he is busy, and what should he do with a big belly by himself.

Immediately, Jiang Yan considered that it was better to take advantage of the fact that his belly was not particularly big now, and he could not apply for her to return to Sijiu City, where there were grandmothers and them, and he could rest assured that he was by his side.

When Jiang Yan was scratching his head at the meeting, a train from Sijiu City to Shengjing was slowly entering Shengjing Station.

"Grandma, how is it, are you tired, or let's find a place to rest first, and then go to the boss after resting." Xu Damao hugged the old lady and persuaded the old lady while getting off the train.

"Tired! All the way is to eat and sleep, sleep and eat, don't mention the bed on this train, it's quite comfortable, and when you go back, let Jiang Yan also book such a train ticket for you. ”

"Now that there is a train, this speed is also fast, I remember when I followed my father to Shengjing, it was a full month of walking. The day came overnight, and it was very fast. The old lady chattered while getting off the train with the support of Xu Damao.

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

When they arrived this time, they didn't bring any less of these things, there were several big bags, everything to eat and drink, and most of these things were prepared by grandma for Jiang Sirui.

To tell the truth, this old lady is also quite a chicken thief, from the moment she decided to go to Shengjing, the old lady went out every day to exchange for national food stamps.

What he considered was that maybe he wouldn't come back in a short time, his food was in Sijiu City, and there was basically no need to prepare a little national food stamps in Shengjing.

This old lady is a snake on the ground, many merchants and old neighbors will give the old lady a little face, the old lady is like this, one two or two, one pound and two pounds are enough to buy for a small two hundred pounds.

What he didn't know was that in Xu Damao's pocket, he had thousands of catties of national food stamps, no way, he was Lou Bancheng's son-in-law, and this little thing was trivial to his father-in-law.

He Yuzhu also exchanged almost 100 catties of national food stamps, and this year, it is still necessary to bring more national food stamps when going out.

After leaving the station, Xu Damao found a few manpower three-wheelers, dragged the luggage with them, and walked over according to the address given by Wang Honghai.
