Siheyuan starts from a good life

A few days later, in the tenth workshop of the steel rolling mill, in a separate compartment of the 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, on behalf of the Third Aircraft Department, I am also entrusted by the Air Force comrades to read out the relevant awards given to you by your superiors."

"In view of Comrade Jiang Yan's significant contribution to my country's national defense construction, with the approval of the relevant superior departments, Comrade Jiang Yan is specially awarded the honorary title of "Aviation Meritorious Officer" and is awarded a first-class merit medal!"

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

Jiang Yan happily took the certificate and medal from Dean Tang and said with a smile: "Don't worry, Dean Tang. I understand this. It's better to keep it safe by yourself and not show it to others easily."

Dean Tang smiled and nodded, and then said: "Comrade Jiang Yan, I have finished talking about the rewards from superiors. Now let me talk about the relevant rewards given to you by our Third Machinery Department."

"After research and decision by the relevant leaders of the Third Ministry of Machinery, Comrade Jiang Yan, the relevant benefits of Level 3 Distinguished Honorary Researcher will be raised to Level 2. However, your matter is still the same as before, only a few people know about it, and you will receive relevant benefits. The welfare benefits are still the same as before. You can come to collect them once a month, or you can collect them all together. It depends on what time is convenient for you. If it doesn't work, we will send it to you."

Speaking of this, Dean Tang immediately laughed.

Then Dean Tang paused, and then continued: "In addition, your special design room needs to be retained for the time being. After the fifth master has gone through the two stages of adjustment test flight and finalization test flight, and is officially installed in the army, your That 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 Machinery Department. I have taken note of all the things you told me."

Today was originally an ordinary day, but after today, it may become a particularly memorable day. Because today is the day when Wu Ye will conduct his first test flight, and it is also a day worth remembering.

Originally, Jiang Yan also wanted to witness the historical moment when Master Wu successfully flew the test flight.

However, some time ago, the Fifth Machinery Department was established and assigned Jiang Yan a confidential imitation task through his superiors. Jiang Yan really couldn't leave for the time being.

Another Jiang Yan believes that he actually didn't put much effort into Wu Ye's improvement project. He just transferred the mature plans and various parameter data of later generations in advance, and also followed some prototypes. equipment, and imitated a lot of related equipment, which is really not a big achievement.

If we really want to talk about the merits, it is those aviation people headed by Mr. Lu who have gone through all kinds of twists and turns, arduous research and unremitting efforts to build the fifth master from scratch, bit by bit. The greatest contribution! It is a glorious moment for the aviation people, led by Mr. Lu and his team.

Jiang Yan, the "porter", was too embarrassed to take up the glory that originally belonged to Mr. Lu and the others at this time. He just made some improvements. This was far less important than them. That is, based on the above Because of this, Jiang Yan could only regretfully miss this opportunity to witness history.

With Aunt Yang's help, Jiang Yan's life got better. It was precisely because of this that Jiang Yan devoted all his body and mind to his work.

"After calculation, I think our Zhan-7 aircraft can adopt an enhanced retractable tricycle landing gear, with the rocker-type nose gear retracted into the front fuselage, the strut-type main landing gear with the wheels rotating and retracted into the fuselage, and the struts retracted into the fuselage. The advantage of the wing is that it can reduce protrusion and increase kinetic energy."

"The overall shape is a pointed triangular cantilever mid-single wing, with a dihedral angle of 2° and a leading edge sweep angle of 57°. The airfoil is symmetrical, with a relative thickness of 5% at the wing root and 4.2% at the wing tip. The aspect ratio is 2.22, with a pointed The cutting ratio is 12.5, the installation angle is 0°, the wing root chord length is 5.97 meters, and the wing tip chord length is 0.46 meters. The flap area is 2x0.92 square meters, and the axis compensation aileron area is 2x0.59 square meters."

At the Zhan-7 meeting, Jiang Yan drew a drawing of this aircraft with a large delta wing while talking.

"Would it be more difficult for us to make it this way?" Suddenly an expert came up with an opinion.

"Yes, but there is nothing we can do about it. The kinetic energy of our engines is limited, so we can only find ways to change the maneuvering layout." Jiang Yan said again slowly.

After hearing Jiang Yan's words, everyone fell silent.

In this way, the layout of the Zhan 7 aircraft was basically decided. Due to limited funds, the superiors, after comprehensive consideration, decided to first develop two versions of a fighter aircraft with nose air intake and an aircraft with chin air intake. As for the Zhan-MF aircraft proposed by Jiang Yan, which is the same as that of later generations, it was shelved first due to problems with research and development costs and technology.

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

Hearing the call from Dean Tang, Jiang Yan quickly returned to his office. The call from Dean Tang came from Nan Fei.

Dean Tang didn't go into details on the phone. He just said that he had already informed the relevant departments and that Jiang Yan needed to come to Nanfei as soon as possible. An hour later, the staff picked him up and asked him to go home. Clean up.

After receiving the call, Jiang Yan's first thought was, could there be something wrong with Master Wu? But now Jiang Yan didn't think too much and went directly to Jiang Sirui's office.

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

"How long will it take?" Jiang Sirui asked.

"I don't know, I guess 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 his secretary Xiao Gong to drive Jiang Sirui back home, and he would sort out the information for the meeting in the office.

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

Because it was an urgent special mission, Jiang Yan's car was not used. Instead, a special car sent by the institute came to pick him up. However, the driver Xiao Wei and secretary Xiao Gong still got into the car with Jiang Yan. When getting in the car, Jiang Yan looked back at the office and saw Jiang Sirui standing at the window looking at him. Jiang Yan waved to her and got into the car with her luggage.

The car that picked up Jiang Yan drove at full speed for about an hour and arrived at an airport.

Although in the 21st century, Jiang Yan often flew by plane, in this era, Jiang Yan only took it twice. After all, this place is a bit far away from the life of ordinary people!

After arriving at the airport, Comrade Qian said to Jiang Yan: "Mr. Jiang, because the situation on Nanfang Airlines is more urgent, in order not to waste too much time, Dean Tang specially coordinated with the Air Force. We need to fly there. Go aside."

"Director Lin, if this is your first time to fly, you may feel a little uncomfortable after you go up to heaven. Please be mentally prepared and try your best to adapt to it." Jiang Yan is afraid that Jiang Yan will not be used to flying for the first time, so Qian Comrade also gave a special reminder.

After getting on the plane, Comrade Qian felt a little uncomfortable and tended to get airsick, but Jiang Yan looked as if nothing had happened and did not feel any discomfort at all.

Taking a plane is nothing new to Jiang Yan. After all, in the 21st century in his previous life, when Jiang Yan first started working as an engineer, he needed to travel frequently across the country. He had to take several flights almost every month. When he came to this world, he took the plane twice, so he had already adapted to it.

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