When Gu Tingting came back, it was already twelve o'clock in the evening, Qin Feng hugged the little tiger's head and slept very sweetly in his arms, but Qin Feng himself had insomnia.

As a test pilot, Qin Feng worked very hard and had to risk his life at any time, but, like him, there are thousands of scientific and technological workers, who are also busy day and night for the cause of scientific research.

In Guizhou, he saw such a scene, in order to make the first flight of Jianjiao 7 as soon as possible, day and night, here, for the first stable aircraft, they are also constantly struggling, it is precisely because of their spirit, the country's science and technology, will continue to progress, the motherland's aviation industry, will continue to achieve the goal of catching up with the world's advanced level, although the motherland is still very backward, but as long as this spirit is there, there will definitely be that day.

He was also proud of his wife.

When Gu Tingting came back, almost her body was soft, and she fell on the bed, she wanted to say a few words to Qin Feng, but she hadn't seen her for a long time, and she should have had a lot of words, but when she got into bed, there was already a gentle sound of sleeping.

Qin Feng's hand was placed on Gu Tingting's hand, held her hand, and slowly fell asleep.

When Qin Feng woke up, the sunlight had already shone into the room, and he touched his side, Gu Tingting was gone.

Qin Feng sat up and looked at the bedside table on the side, there was a note, it turned out that Gu Tingting had already gone to work again, and when she saw that Qin Feng and Xiaohutou were sleeping soundly, she didn't wake them up.

So, Qin Feng patted Xiaohutou's buttocks, told Xiaohutou to get up, brush his teeth, wash his face, eat breakfast, and send Xiaohutou to kindergarten.

Xiaohutou is very well-behaved, many children will cry and shout when they go to kindergarten, but Xiaohutou didn't, he obediently said goodbye to Qin Feng, but when he waved his hand, he asked Qin Feng: "Dad, will you come to pick me up at night?" ”

Qin Feng nodded: "During this time, I will be here, I will come to pick you up every day." ”

"Dad, I love you." The little tiger head said, and ran inside with a smoke, leaving Qin Feng stunned outside, this sentence made Qin Feng's heart warm.

Qin Feng looked at the back of Xiao Hutou leaving, and an inexplicable feeling emerged in his heart, he looked there for a few seconds, and finally turned his head, Xiao Hutou was already so sensible, and he had to do the right thing.

As soon as he walked back to the office building of the test flight institute, Qin Feng saw a familiar figure, and immediately shouted: "Old Tu, why are you here?" ”

Tu Lao's thin body turned around, looked at Qin Feng who appeared in front of him, and was also happy: "Qin Feng, I haven't seen you for a long time, I saw the Seven Sect Destroyers flying over yesterday, and I guess you are here too." ”

"What? Have you been here lately? ”

Tu Lao nodded: "Yes, but I haven't been here all the time, I'm mainly in the 618 Institute, and I'll stop by to do something." ”

The 618 Institute, founded in the sixties, this research institute is mainly used to study aviation flight control systems, and it is said that it is also developing domestic independent aviation inertial navigation systems to make up for the gaps in the country.

Tu Lao has almost nothing else to do now, just busy with the improvement of Jianqi, coming here, he must not be able to engage in the cooperation project with Pakistan, in addition to this project, what else must be done here?

Qin Feng quickly understood: "Is it about the improvement of the J-7M?" ”

Tu Lao smiled and nodded: "Yes, we found the Western University of Technology, but only the Western University of Technology is not enough, so we have pulled up 618 institutes, funded by our 132 factory, and asked them to help us complete the performance calculation of the J-7M." ”

Tu Lao patted Qin Feng on the shoulder: "How about it, come over with me?" ”

Of course, Qin Feng wanted to go, but he still had a task to do.

"I'm going to fly to destroy the Seventh." Qin Feng said.

"You, it's late today, look at it, Annihilation Sect Seven has already taken off." Tu Lao said.

Qin Feng returned to the test flight yard, his wife and children were here, and he got up late again today, so no one called him, Tang Gang himself had already begun to fly.

This young man can finally be on his own, Qin Feng secretly sighed in his heart, since this is the case, then it is okay to go out and have a look by yourself.

This is also an important task, if it is done well, maybe it can be applied to the body of the Annihilation Sect Seven? Qin Feng used this reason to convince himself.

"Okay, then I'll go over and have a look."

The two research institutes were not far away, and soon, Qin Feng arrived with Tu Lao and others, and in the conference room of the 618 Institute, Tu Lao happily introduced Qin Feng to everyone.

"Okay, let's get down to business, this time it's mainly our tripartite alliance to complete the most important improvement plan of our Jian-7M." Tu Lao said: "In the past, we didn't completely eat Jianqi, so when we changed, we couldn't do what we wanted, this time, we just want to thoroughly eat it, and we have two main tasks." ”

Qin Feng has already taken out two contracts from Tu Lao, one is "J-7M Stable Quality Calculation", and the other is "Cancel the counterweight and relax the calculation of the static stability control law." ”

This kind of purely theoretical calculation, the 132 factory itself really can't do it, but now, the 132 factory earns foreign exchange through exports, and the waist bag has been bulging, so you can also carry out some projects by yourself, if these two projects can be completed, it will be another improvement for the J-7 M, because the cumbersome counterweight can be canceled, and I didn't dare to do it before, there is a reason, the shock of the J-7 this time is caused by the problem of the center of gravity.

Now, through the scientific way, eat it and solve it!

The control rate of the aircraft is a very important thing, and now Gu Tingting has been busy with the programming, which also relies on the control rate of the flight, and when he thought of this, Qin Feng suddenly had a flash of inspiration.

"Since we can all relax and stabilize, why not just do an ACT?"

Relaxing static stability, you can further improve the performance of the aircraft, if you apply active control technology, then the J-7M and F-16 grappling, it is not impossible.

As soon as Qin Feng said this, Tu Lao was stunned, he hadn't learned to walk yet, was he going to run?

ACT technology, which is based on the digital fly-by-wire flight control system, now, the experimental aircraft of the test flight institute has not yet been seen, and it is very difficult to do it yourself, but this idea is very good and can be retained.
