A few days later, the rolling mill was in a separate compartment in the tenth workshop, a special design room.

Dean Tang first chatted with Jiang Yan for a few words, and then said to Jiang Yan very formally: "Comrade Jiang Yan, now on behalf of the Third Aircraft Department, and at the same time entrusted by the comrades of the Air Force, I will read out the relevant commendations given to you by my superiors. ”

"In view of the major contributions made by Comrade Jiang Yan in China's national defense construction, with the approval of the relevant departments at a higher level, Comrade Jiang Yan is hereby awarded the honorary title of "Aviation Meritorious Hero" and a first-class meritorious service medal! ”

After finishing the things assigned by his superiors, Dean Tang said with a smile: "Comrade Jiang Yan, about certificates and medals, we still have the old rules. ”

Jiang Yan happily accepted the certificate and medal handed over by Dean Tang, and said with a smile: "Don't worry, Dean Tang, I understand this, and I still keep it properly by myself and don't show it easily." ”

Dean Tang nodded with a smile, and then said: "Comrade Jiang Yan, I have finished talking about the reward of the superior, and now I will talk about the relevant reward given to you by our Third Machine Department." ”

"After the relevant leaders of the Third Machinery Department, it has been decided to upgrade the relevant benefits of Comrade Jiang Yan, your Level 3 Distinguished Honorary Researcher, to Level 2. However, this matter is still the same as before, only a few people know, and the relevant benefits are still the same as before, you can come to receive it once a month, and you can save it together to receive it, depending on what time is convenient for you, if it doesn't work again, we will send it to you. ”

Speaking of this, Dean Tang laughed directly.

Then Dean Tang paused, and then continued: "In addition, your special design room needs to be kept for the time being, and after the fifth master has gone through the two links of adjusting the test flight and finalizing the test flight, and officially installed the troops, your special design room will be officially abolished." ”

Jiang Yan nodded with a smile and said, "Thank you for the commendation and reward from your superiors and the Third Machine Department, I have written down all these things you have explained." ”

Today was originally an ordinary and ordinary day, but after today, it may become a particularly memorable day. Because today is the day when the fifth master is going to make his first test flight, and it is also a memorable day.

Originally, Jiang Yan also wanted to witness the historical moment of the successful test flight of the fifth master.

However, due to the fact that some time ago, the established Fifth Machine Department issued a confidential imitation task to Jiang Yan through his superiors, and Jiang Yan really couldn't leave for the time being.

Another Jiang Yan thinks that he really didn't make much effort in the improvement project of the fifth master, he just moved out the mature plans and various parameter data of later generations in advance, and also imitated a lot of related equipment according to some prototype equipment, which is really not a big credit.

If you really want to talk about the merits, it is still those aviation people who have gone through all kinds of twists and turns, arduous research and development, and unremitting efforts to build the five masters from scratch little by little, led by Chief Engineer Lu, and their contributions are the greatest! It belongs to the glorious moment of aviation people led by Chief Engineer Lu and his team

Jiang Yan, the "porter", was embarrassed to share the glory that originally belonged to Chief Engineer Lu at this time, but he just improved it, which was far less important than them, that is, based on the above reasons, Jiang Yan could only regretfully miss this opportunity to witness history.

With the help of Aunt Yang, Jiang Yan's life got better, and it was because of this that Jiang Yan better put all his body and mind into work.

"After calculation, I think our Zhan-7 aircraft can use a reinforced retractable front three-point single-wheel landing gear, the rocker arm nose landing gear into the front fuselage, the pillar main landing gear wheel rotation into the fuselage, and the pillar into the wing, so the advantage is that it can reduce protrusion and increase kinetic energy."

"The whole is a cut-out triangle cantilever type mid-wing, with a lower reverse angle of 2° and a leading edge sweep angle of 57°. Symmetrical airfoil, 5% relative thickness at the wing root and 4.2% at the wing tip. The aspect ratio is 2.22, the sharpness ratio is 12.5, the mounting angle is 0°, the wing root chord length is 5.97 m, and the wing tip chord length is 0.46 m. The flap area is 2×0.92 square meters, and the axle-compensated aileron area is 2×0.59 square meters. ”

At the battle-7 meeting, Jiang Yan said while drawing the drawings of this aircraft with a large delta wing.

"Won't it be more difficult for us to make it in this way?" Suddenly, an expert came up with an opinion.

"There is a point, but there is no way, the kinetic energy of our engine is limited, so we can only find a way to change the dynamic layout." Jiang Yan said again slowly.

Hearing Jiang Yan's words, everyone didn't say anything more.

In this way, the layout of the Zhan-7 aircraft was basically decided, and due to the limited funds, the superiors decided to first develop two versions, namely, a fighter with nose intake and an aircraft with jaw intake. As for the Zhan-7MF aircraft proposed by Jiang Yan and later generations, it was stranded first due to problems with research and development costs and technology.

"Leader, Dean Tang's phone call." As soon as he left the conference room, the secretary Xiao Gong greeted him and whispered to Jiang Yan.

Hearing Dean Tang's call, Jiang Yan quickly returned to his office, and Dean Tang's call was from Nanfei.

Dean Tang didn't elaborate on the phone, but just said that he had already greeted the relevant departments there, and he needed Jiang Yan to hurry up to Nanfei's side, and an hour later, the staff would pick him up and ask him to go home and clean up.

After receiving this call, the first thought in Jiang Yan's mind was, could it be that something was wrong with the fifth master? But now Jiang Yan didn't think much about it, and went directly to Jiang Sirui's office.

"My superiors arranged for me to go on a business trip to Nanfei, and I will leave immediately." Seeing Jiang Sirui, Jiang Yan was not polite, and spoke directly.

"How long is it going?" Jiang Sirui asked.

"I don't know, it won't be short, can you go home and help me pack my things, I need to sort out the information here."

Jiang Sirui nodded, and Jiang Yan arranged for the secretary Xiao Gong to drive Jiang Sirui back to his home, and he sorted out the materials of the meeting in the office

After a while, Comrade Qian, who was in charge of the contact between the research institute and Jiang Yan, came to pick up Jiang Yan.

Because it was an urgent special task, Jiang Yan's car was not used, but a special car sent by the research institute was used to pick it up, but the driver Xiao Wei and the secretary Xiao Gong still followed Jiang Yan into the car. When she got into the car, Jiang Yan glanced back at the office and saw Jiang Sirui standing at the window looking at herself, Jiang Yan waved her hand and got into the car with her luggage.

The car that picked up Jiang Yan drove all the way for about an hour and drove to an airport.

Although in the 21st century, Jiang Yan often took planes, but in today's era, Jiang Yan has only taken twice, after all, here, and the life of ordinary people, a little far away!

After arriving at the airport, Comrade Qian said to Jiang Yan: "Mr. Jiang, because the situation over there is more urgent, in order not to delay too much time, Dean Tang specially coordinated the Air Force side, and we need to fly there." ”

"Director Lin, if you are taking a plane for the first time, you may feel a little uncomfortable after you go to the sky, please be mentally prepared and try your best to adapt to it." Afraid that Jiang Yan would not be comfortable taking a plane for the first time, Comrade Qian also reminded him of it.

After getting on the plane, Comrade Qian was a little uncomfortable and had a tendency to get motion sickness, but Jiang Yan looked like nothing had happened, without any discomfort at all.

This plane ride is not a new thing for Jiang Yan at all, after all, in the 21st century in his previous life, when Jiang Yan first became an engineer, he needed to travel all over the country frequently, and he had to take the plane several times a month, and when he came to this world, he also took it twice, so he had already adapted to it.

It's just that he didn't say it.
