In this way, in the process of constantly discovering problems and dealing with problems, the project slowly ran up, and Li Zhao, who had followed the project for a period of time, also returned to his work, the agricultural project is basically like that now, he has more important things to do, and when the agricultural project is seriously lacking, he will go on top, that is, it is obviously unrealistic to want him to stay there to help, after all, the aircraft project is more important.

In fact, to put it bluntly, it is unlikely that the higher authorities will leave so much land and population in the name of the 998 factory, especially in the capital, and now the factory has basically taken over nearly half of the population of the capital, at most three or two years, when these projects are smoothed out, the farm will definitely be split directly according to the town level.

Such a farm of two or three hundred thousand people, even if it is not much or less, the difficulty of management will be much smaller, after all, now Li's father is already very busy, every day a small half of the time, is to run around by car, he has to inspect the construction site every day, and all aspects of things need to be checked, in case there is a mistake, of course, he is far more than one person who does these things, but who made him the general person in charge of the agricultural project, it is not normal if he is not busy.

At this stage, Li Zhao's most important work is to complete the wind tunnel test of the aircraft model as soon as possible, only when the aerodynamic layout is finally determined, can the development of the aircraft be promoted to the next stage, that is, the trial production stage of the verification machine, as long as the aerodynamic layout does not need to be changed, then the basic design will not need to be changed for the time being, and the trial production of the verification machine can be entered as soon as possible.

Shortly after Li Zhao returned to work, the aircraft wind tunnel test model arranged by Li Zhao years later was completed, to be honest, the people of the UAV project team really understood this small model aircraft, and the processing speed was fast enough, and they also had an idea, and directly made the current startup layout into a mold, that is, as long as they needed, they could transform the current model into a drone.

This is also a good idea, but Li Zhao needs to come up with a small special engine, but Li Zhao will not have time to do this for a while, maybe they will develop the corresponding components themselves, after all, for a period of time, they have also been fully involved in the aircraft project, and they have an understanding of each part.

In addition to the fast processing speed, the more important thing is to do it fine enough, looking at the model that is fixed on the bracket, Li Zhao is also emotional, he didn't expect that the model made by these people can directly control the flaps and rudder, which is much stronger than the general model, if there is a suitable engine, this model can be directly used as a drone, of course, this is very friendly to the test.

Li Zhao doesn't know much about wind tunnel testing, he used to follow others to run on the simulation software, this kind of real thing in the wind tunnel test is the first time, so during the test, he has been watching from the side, all the work has been handed over to the drone team, other interested people, have also come over, ready to follow the learning, and most importantly, the best pilots are also the participants in today's test, they are more experienced.

But this is actually very good, Li Zhao now has no need to do a lot of work himself, what he needs to do most is to cultivate talents, to be honest, the projects he can complete alone are very limited. Just like alloy research, he basically just went to a meeting after a while, and then paid attention to their various reports, and now he rarely interfered with their thinking, after all, Li Zhao did very little work in this regard.

A lot of times, if you don't get involved, you'll quickly fall behind, and if you wait for a while, and then you want to participate, then you need to learn for a long time. Of course, now Li Zhao also has projects that he pays more attention to, which he has spent a lot of energy, such as CNC machine tools, generator sets, tanks, etc., these relatively large projects, such as bicycles and other small projects, he has completely ignored, after all, the energy is really limited.

Just like the agricultural projects that Li Zhao wants to do, he will rarely do them in the end, especially in the past two years, he basically rarely spends weekends, and he really has no time. For example, the bicycle project is a project that Li Zhao completely lets go, and many times, such projects have been reduced to projects to cultivate new people, but anyone with a little strength is not very willing to pay attention to these projects, of course, this is not out

Now what is the problem of the situation.

The method used in the current wind tunnel test is called the smoke flow method, which is to mix a certain amount of smoke into the air flow, and when the smoke flows through the model, it can be very obvious to see the flow of air in various states. What needs to be done in the test is to adjust the attitude of the model and the state of the flaps and tail rudder from time to time to see the changes in the airflow under each attitude, so as to determine whether each part of the aircraft is suitable.

This method can observe the state of the airflow in real time, especially in what kind of attitude will produce turbulence, which is very important for the future control of the aircraft, after all, when there is serious turbulence, the aircraft is likely to directly lose lift, which will lead to disaster, so the smoke flow method is a more commonly used method.

With the operation of the testers, the model began to change various states, Li Zhao is still very satisfied with the results, without him, the current results, and the results of running on the software are not much different, the aerodynamic layout of the aircraft is decent, or more reasonable, it is more suitable for the aircraft situation of this era.

You must know that the electronic technology of this era is very backward, so Li Zhao basically did not engage in components that require multi-faceted cooperation, such as canard wings, which can only play a role after computer coordination. Coupled with Li Zhao's self-confidence in the engine, when designing the aerodynamic layout of the aircraft, he directly focused on simplicity, and of course did not engage in any variable sweep wings, which had too many requirements for the production process.

Although the variable swept wing is very good for high altitude and high speed, it is also not available in order to reduce the difficulty of manufacturing. All operations in this era are basically manual, if you make something complicated, I really don't know what the consequences will be, and it is very possible to destroy people if you want to come to the machine, of course, it is not without advanced places, the famous clam air intake, Li Zhao still knows, this item, added in.

After getting the conclusion that the aerodynamic layout is reasonable, the development of the aircraft has also entered a new stage, yes, Li Zhao is ready to directly carry out the manufacture of the verification machine, at this time everyone is very excited, to be honest, they never thought that the wind tunnel test could be completed so smoothly, and Li Zhao is a little confident.

Of course, the verification machine has entered the manufacturing stage, also because there has been good progress in other aspects, such as radar, which has basically completed the design and is ready to be manufactured, and according to the statement given by the project team, the performance of this radar is still good, of course, the weight is also okay, the weight of 300 kilograms is directly reached, but the detection distance is given a mark of 200 kilometers, and the power consumption is OK, only 20 kilowatts.

It's just one point, there is no guarantee of reliability now, and it needs to be tested after it is manufactured, but on this data, Li Zhao feels very good, but I don't know how the real thing is, I hope there will be no problems, this is also the best design that radar research has come up with in the past few years, and there should be nothing better than this in a short time.

In addition to the radar system, there are electronic systems, and now they have come up with a set of plans, ready to test, but I don't know how the effect is, it is estimated that at the beginning, it may be necessary to install two sets of flight control systems, and now the electronic systems are generally backward, and the test personnel do not dare to guarantee the reliability of the electronic system, even if the fly-by-wire flight control can be used, but no one dares to guarantee the stability of the system, if there is a problem, it is a big deal.

In this case, it can only be like this, put the two sets of flight control systems into it, if the fly-by-wire flight controller can be used, then it is the fly-by-wire flight control, if it is unstable, then use the hydromechanical flight controller. Li Zhao must put the fly-by-wire flight controller into it, after all, when this matures, it can greatly reduce the weight of the aircraft, every bit of weight on the plane is very important, it is impossible to give it casually, and it must have an effect.

In fact, in order to reduce the weight now, Li Zhao is ready to use a part of the composite material, of course, it also depends on the final cost and results, if the cost of carbon nanofiber tubes is not high, a part will be used, of course, this completely depends on the actual situation, Li Zhao will not be reluctant. In addition to these, the most progress is the engine, and now the development of the engine has also entered a new stage, and Li Zhao is already working hard for the final finalization.

Through three batches of tests, Li Zhao has been able to do so now

It's almost time to come up with all the process tests, and it's time to come up with the final process, so it can be said that after taking out the processing technology this time, it is basically finalized. Of course, there are still many new tests before finalization, such as foreign object damage tests.

The previous test is to test the damage of parts under various thrust, the new batch is to determine the processing technology, it is necessary to test the specific situation of the engine after the foreign body enters, such as water mist, ice crystals, birds, etc., which is very easy to encounter some scenes at high altitude, test the engine, these environments must be taken into account.
