"Tang Gang, are you the second? That's great! When he returned to the 611 Institute, Qin Feng got a piece of news that made him even happier, the cumbersome YES/NO experiment, in addition to Qin Feng's pass, a second person appeared, this person was Tang Gang!

No one thought that Tang Gang, the youngest and the least experienced Tang Gang, passed this experiment for the second, and the other people had envious expressions on their faces, and at the same time, they were also secretly cheering themselves up, come on, they would definitely pass!

After completing this experiment, what is next? Before going to Israel to learn how to control, you have to learn the knowledge of the third-generation aircraft yourself!

There is no third-generation aircraft in China, where can the knowledge be learned? From the researchers, of course.

"Li Jun, Haitao, you all have followed Comrade Xiao Yang." When Qin Feng took Tang Gang to the newly established flight control department of the design institute, he saw several familiar faces.

Seeing Qin Feng, they were also very happy: "Yes, we have been busy with the J-9 project, and our No. 10 project is inherited from the J-9 project, so we are the most familiar with it, and with Comrade Xiao Yang, we can get familiar with it as soon as possible and lay the foundation for the development of the flight controller." ”

Although the J-9 project was discontinued, they have been sorting out the information of J-9, and now it has finally come in handy.

Although Comrade Xiao Yang only came last year, he was a top student of the Western University of Technology, and Zhang Lijun and Ma Haitao were just draftsmen, so they were already very satisfied with Comrade Xiao Yang entering the new department.

"Let's also learn together, mainly because of the flight control of our third-generation aircraft, please give me more advice in the future." Qin Feng said quite politely.

The information here, they can flip through it casually, and after entering here, Tang Gang is like jumping into the ocean of knowledge.

"The fly-by-wire control of the third-generation aircraft is mainly to replace the operation of people with computers, it is only to sense people's intentions, push the operating lever, that is, to dive, at this time, you don't have to care about the specific operation of the aircraft, how to turn the canard wing in front, how to move the tail rudder behind, the angle of your push rod is large, the plane dives fiercely, the angle you push is small, and the dive is slow." Qin Feng gave Tang Gang a preliminary introduction.

"In the same way, if you let go of the operating stick, it means that if you don't operate, the plane will be automatically leveled, of course, what is the state of the aircraft at this time, how to level it, it is not necessary for the pilot to control, it is automatically judged by the on-board computer." Qin Feng continued.

This is different from the flight of the second-generation aircraft, you have to take care of the rudder surfaces, you have to react how to operate, if you release the operating stick, the fighter will definitely not level itself, will continue to fly in the original direction, this is the huge difference between the third-generation aircraft and the second-generation aircraft.

"All the control is calculated by the computer itself, as for how to calculate, such as when you push the rod, which rudder surface moves, how much it moves, this requires a complete set of programs, and this set of procedures is the control rate of the aircraft, whether the control of the aircraft is appropriate, completely depends on this set of control rate."

Qin Feng's introduction is already very detailed.

"So, who determines the control rate?" Tang Gang asked.

Qin Feng pointed to Xiao Yang's back: "It's them." ”

They're going to develop a new brain! The electrical signals controlled by wire are transmitted to the on-board computer, and how to control them is all programmed by them.

As if knowing what Qin Feng was talking about, Xiao Yang turned his head: "Of course not, the control rate of this system, as long as we do it, but the task of the test pilot is also very large, the test pilot has to study this set of control rate, determine whether this set of control rate is appropriate, and give us suggestions for improvement, so that we can make progress together." ”

This is an important role for test pilots to get involved, to study whether the control system of the aircraft is suitable!

"Yes, we will definitely do it, this overseas training is to find experience in this area, in the future, maybe we will have frequent quarrels." Qin Feng said with a smile.

This kind of quarrel has been seen by Qin Feng more than once, starting from the initial issue between Tu Lao and Song Lao about the mapping and imitation of the MiG-21MF.

After all, Qin Feng knows that in scientific research, it is not appropriate to obey other people's opinions, when he has objections, he must be brave to put forward, to explain his own views and opinions, quarrels are not terrible, in quarrels, to find the right conclusion, this is the most important thing.

"yes, I'm ready." Xiao Yang said.

"By the way, our group is mainly studying the software aspect, but how to solve the hardware aspect?" Qin Feng asked towards Xiao Yang.

This kind of digital telex system, including software and hardware, of which software is the most important, a small parameter is not set properly, may lead to the test flight accident of the fighter, and the hardware, is also very important, after all, the hardware is to carry instructions, to make actions.

"In terms of hardware, we are also considering it." Xiao Yang said: "What we need is a three-axis and four-redundancy digital control system, and now, what we have made in China is the single-axis control system on the BW-1." Now, the hardware of this system has been equipped, the software is in the final debugging stage, we have also heard, they are based on this system, the development of a set of three-axis and four-redundant fly-by-wire control system, code name 634 system, now our plan, is to transplant this system over, as our hardware, and then, on this basis, we write our own flight control software, and finally realize the development of this control system. ”

The hardware of this system needs to be ported, and there is no need for 611 to develop it itself, the main thing 611 does is to write software, which is also the most appropriate way.

"So, Comrade Qin Feng, it would be better if you mobilized your wife to join our project, our side lacks a talent who understands hardware." Xiao Yang said to Qin Feng.

Qin Feng's wife, Gu Tingting, has been involved in the research and development of the BW-1 stabilization machine project and has sufficient experience, and at the same time, with Qin Feng returning to Chengdu, if Gu Tingting also returns, the two will be together in the future.

Therefore, Xiao Yang can't wait to dig people.

Qin Feng smiled bitterly: "This, I respect her personal opinion, for her, the BW-1 stabilization machine is her career, and she has to make her own choice." ”

Qin Feng knows Gu Tingting, she has paid a lot for the stabilization machine, and now that the stabilization machine has not made its first flight, how could she leave? When this project is brought to a successful conclusion, she should not think about other aspects, right?
