Although there have been patrols around the factory, Li Zhao is still a little uneasy, like such an important drawing, he does not dare to be sloppy at all, of course, this also has something to do with too many drawings, directly is a few boxes, if he moves it himself, he has to move many times, after moving the drawings into the office of the aircraft factory, Li Zhao also began to transfer personnel to various research institutes, such as the radar research group, and now they have to move directly to the aircraft factory to work.

In addition to them, the personnel in electronics, communications, computers, machinery, metals, non-metals, medicines, weapons, unmanned aerial vehicles, etc., the project team formed this time is the largest and most complex project team since the establishment of the 998 factory. Of course, the people in the weapons research institute let them study machine guns and aerial bombs, but they can't do it with missiles, and as for the medical research institute, they are engaged in life-sustaining systems.

As an aircraft with an altitude of more than 20,000 meters, there is no life-sustaining system, which is simply not possible, and they need to improve it according to the existing life-sustaining system, after all, this is a more demanding fighter, and there are higher requirements for pilots, even if it is to select test pilots in the future, it is necessary to re-select and train before it can be operated on the plane, after all, the overload of this fighter can be greater than that of previous aircraft.

Personnel notice selection in place, early the next morning, all the personnel arrived at the aircraft factory, Li Zhao began to open an aircraft project meeting for everyone, Li Zhao first introduced the details of the aircraft, and then began to describe the requirements of each part, and gave the corresponding drawings and other aircraft drawings for reference, as for the physical object, you need to wait a while, the application has not been handed in, after the need to come down, the personnel of each part of the application themselves.

The reason for this is that Li Zhao has no concept of many things, and needs the corresponding professional personnel to study on their own, of course, this is not such an abrupt thing, after all, Li Zhao has asked many departments to start the preliminary research work last year, which will not be like a headless fly, after all, Li Zhao's drawings have not been seen here, but they have seen the drawings of other aircraft, and they are no strangers to various parts.

After the introduction, Li Zhao sent down the drawings of each part, and then said: "Last year, our wind tunnel was completed, and the first thing to do now is to make a model for wind tunnel testing, and hand over the work of making the model to your drone project team, no problem, right?" You're pretty familiar with this."

At this time, the person in charge of the drone project team said: "No problem, we have done many wind tunnel tests, we are very experienced in making models, and we also have the records and test methods of wind tunnel tests done by others, we are already very experienced in these, and there will be absolutely no problems."

After listening to this, Li Zhao said: "In the future, it is estimated that everyone will have more times to deal with wind tunnel tests, so the content related to wind tunnel tests, the personnel of the mechanical part will try to participate in it, and in the follow-up research, you will also have more contact, and learning with them will allow you to learn how to use it faster."

Li Zhao's words, they naturally knew that it was for their good, so they readily agreed, and now the most used wind tunnel in the factory is the UAV project team, followed by the weapons research institute and the vehicle research institute.

Because the drawings on Li Zhao's side were not completed, the aircraft project was not fully formed, and all parts were rehearsed according to the tasks arranged by Li Zhao at that time, so the wind tunnel has been useless, which gave the UAV project team and the people from the Weapons Research Institute a chance, not to mention the UAVs, they are verifying the aerodynamic layout, and the Weapons Research Institute is mainly conducting fluid dynamics research on various shells and rockets.

For this piece Li Zhao also knows that there is such a thing, but to what extent the specific progress, Li Zhao does not know, but it will definitely be useful, Li Zhao is convinced of this, after all, flying in the sky, the flight process will definitely be affected by the air, study the shape, it is possible to fly farther, hit more accurately.

As for the aerodynamic layout of the aircraft designed by Li Zhao, there should be no problem, after all, he has reference objects, and there are many, and there are many ways of aerodynamic layout of the aircraft in his mind, all of which have been run through wind tunnel simulation software. To be honest, the wind tunnel simulation software after 60 years is already quite powerful, and it should be no worse than going directly to the wind tunnel in this era, why

It is also necessary to conduct wind tunnel tests, also to be safe.

After all, when the wind tunnel test, it is still necessary to test the working condition of the rudder surface, because it is the first verification machine to be made, so Li Zhao's design is still a bit conservative, such as the turning radius, Li Zhao's design is estimated to be about three or four hundred meters, after all, when turning, it is controlled by the tail rudder, Li Zhao does not dare to guarantee that when the turning radius is too small, there will be any problems, so the design is more conservative.

It is impossible to compare with the heavy fighter with a turning radius of only more than 100 meters in the future, of course, because this is the first verification aircraft, so many designs are relatively conservative, even the aerodynamic layout, which is the most classic mode, there are no bells and whistles at all, and there is no complex operating system.

After arranging the wind tunnel model, Li Zhao began to arrange other things, and listened to Li Zhao say: "I have designed two modes for the flight controller, one is the hydraulic transmission mode, which is the mode mainly used by the aircraft now, which is very mature and has good reliability, but it is relatively heavy, for us, if the aircraft can reduce the weight, it can save fuel and fly higher and faster, so I came with a fly-by-wire flight controller."

"The fly-by-wire flight controller is a more concise and lighter control system, and in the case of difficult operation, it is also easier to operate, but the fly-by-wire flight controller, I can only complete the mechanical part, the control part needs you to complete, and you need to design the corresponding control system, you also know that I have not studied much on the electronic part, and basically cannot give you any useful reference, but I can handle the mechanical part."

"It is for this reason that I have designed two flight control systems, if you can't solve the problem of fly-by-wire flight control when you make the prototype, then we will be a fly-by-wire flight control system, and the use of fly-by-wire flight control will be delayed, we need to come up with results as soon as possible, this project has spent more than a billion dollars, from the very beginning of the preparation of equipment, it has been more than three years now, so I want to come up with a little bit of results as soon as possible."

As soon as Li Zhao's words fell, the electronics and computers said that there was no problem, and they would do their best to complete the design of the fly-by-wire flight control and ensure that it would be taken out when the first prototype was produced.

Just after arranging the flight control, Li Zhaoyou said to the people in the radar project: "Radar is the top priority, only excellent radar can ensure the combat effectiveness of the aircraft, you also know, I give you the weight limit is not to exceed 300 kilograms, the farther the detection distance, the better, my basic requirement is not less than 80 kilometers, but it is best to more than 100 kilometers, it is best to reach 200 kilometers, I don't know if you have the confidence to complete this radar?"

As soon as Li Zhao's words fell, the person in charge of the radar project said: "Chief Engineer Li, there is no problem at all, my research in the past few years has not been in vain, we have been designing radar, although when testing, the effect is not very good, but I have figured out the key in the middle, I dare not say more, I can still guarantee the detection distance of more than 100 kilometers, after all, the weight you allow is 300 kilograms, not 100 kilograms."

Li Zhao's requirement is actually not high, after all, this is a radar that uses chips and transistors, not an electron tube radar, and the weight is relaxed to 300 kilograms, you must know that the more classic APG 63 pulse Doppler radar, weighing 220 kilograms, has a detection distance of 185 kilometers, while Li Zhao gave a weight of 300 kilograms, and the required detection distance is only required to be at least 80 kilometers, which is very low.

Of course, for radar, it is best to be able to detect 200 kilometers, but Li Zhao estimates that the possibility of them completing it is very small, and there is no need to daydream at all, after all, the technology gap is still relatively large, and at the same time of starting late, there are few researchers, although the factory gives sufficient expenses, but where is the gap easy to erase? It takes time, even though they've been working on it for years.

Just when Li Zhao finished arranging these, someone from the Mechanical Research Institute said: "Chief Engineer Li, in fact, we don't have any specific concept of aircraft, can you apply for an aircraft to come over, let's take it apart and study it, so that we can get started faster

。」

After Li Zhao heard this, he thought for a while and said, "It's okay, not only you, but also the Medical Research Institute, I guess I don't have any concept of the life-sustaining system, I'll see if I want to take you to the barracks for a visit, or let the superiors put one directly to us for us to study, you go back and study the drawings first, if you have any questions, we will communicate in detail, but the time for this project will be relatively tight, everyone must be prepared."
