Early the next morning, after breakfast, Li Zhao, Su Ya and Lou Xiao'e, helped Nastya with her luggage and went to the meeting place, which is the company's dormitory.

When they came here, most of the people had already gathered, and they would leave by bus after a while, at this time, whether Su Ya, Lou Xiao'e or Nastya, they were all in tears, this time Nastya could be regarded as an unexpected joy, and seeing each other again was far away, but time always went without looking back, and soon it was time to depart, Nastya was also urging, got into the car, and as the vehicle went away, she could still be seen waving her hand.

Looking at Su Ya, who was in a bad mood, Li Zhao was also very uncomfortable, took her into his arms, and hugged her hard, at this time Li Zhao said, "If you don't go to work today, how about I go out with you for a walk?"

Su Ya was embarrassed to be taken by Li Zhao like this, but still said: "Forget it, you have been too busy for a while, you have been delayed a lot of time recently because of agricultural matters, and your project is also a critical period now, I am just a little lost when my friend left, just go back and get busy."

Li Zhao heard Su Ya say this, and also said, "Is it really okay? If I get busy, I won't have time recently, and if I want to have time, I guess it will be half a month at the earliest, and if there is nothing to do, I will be in the test workshop for a long time recently, so I really don't have time."

After nearly two months of hard work, the aircraft is now almost assembled, the project team is now summarizing the installation process, and Li Zhao is also organizing the next stage of static testing, of course, there are some other small experiments will be done together, such as the calculation of mass distribution, although the design has been taken into account, but obviously it is necessary to make a calculation to clarify whether it meets the design requirements, after all, there will be errors when producing.

The second is the system detection, although the overall completion of the verification machine, but whether there will be problems in each part, now no one knows, especially the electronic system, if it can not operate normally, the problem is very big, and then radar, the total weight has reached 300 kilograms, the final design energy consumption is 15 kilowatts, when running on the aircraft will not have any problems, these need to be tested first.

The problem of these things can not be brought to the sky, if there is a problem in these places in the sky, then it may bring very serious consequences, of course, this plane wants to fly into the sky, it is impossible, after all, the final static test, there will be a certain amount of destructiveness, may directly make the aircraft with hidden dangers, in this case, it is obviously not suitable for flying, and after these tests are carried out, you can start to produce the second one.

Basically, the flight test will start on the second one, Li Zhao does not know how other aircraft factories operate, but he will definitely not dare to let the plane take off before verifying the structural strength of the aircraft, you must know that the thrust of this aircraft is very strong, once the strength is insufficient, then it is very easy to have problems, just like many aircraft, because of insufficient strength, there has been a direct disintegration in the air.

And these experiments will be concentrated in the next period of time, so Li Zhao will be very busy, of course, Su Ya obviously knows about this situation, leaned in Li Zhao's arms for a while, adjusted her mood, and said: "It's better to be busy with work, I also have a lot of things to do in my hands, and I have delayed a lot of time in the previous period, if I still go to play today, I may have to work overtime at night again, but you can't finish your things at night."

Seeing this, Li Zhao no longer insisted, sent her to the office, and went to the test workshop, as for Lou Xiao'e, she has not returned to work yet, and she will go home after sending people off, of course, she is estimated to be going to work soon, it is estimated that it will be after He Yushui's college entrance examination, after all, at that time, she has also been cultivating for two months.

When I arrived at the test workshop, I greeted everyone, and Li Zhao also started to work, at this time the plane was almost finished, but it was not painted, and the bolts could be seen on the silver-white fuselage, but they were not convex, Li Zhao did not use the more popular riveting structure in this era, but used the future countersunk self-locking screws as skin fasteners, this kind of thing, of course, Li Zhao is very

Distinct.

Of course, the cost will be much more expensive, but relatively speaking, there are still many advantages, at least it will not increase the resistance, and at the same time, there is no need to thicken the surface coating in order to cover the rivets.

The test that will be carried out today is very simple, that is, to measure the weight distribution of the aircraft, and the maintenance personnel are very skilled in this work, which makes Li Zhao very surprised, because of the surprise, Li Zhao can't help asking, "Why are you so skilled in measuring this?" Do you want to measure these often?"

In response to Li Zhao's question, the captain said: "Of course, you may not know, in fact, measuring the weight distribution of the aircraft is a very important test, once the center of gravity of the aircraft is offset, then the aircraft will be very difficult to control in flight, so one of our usual jobs is to measure this."

Hearing this, Li Zhao knew what was going on, and soon the measurement was completed, and everyone looked at the measurement results together, and quickly concluded that it met the design requirements, yes, the weight distribution is very good, but the matter is far from over, the next thing is to refuel, and then continue to measure, the fuel on the plane is very much, and with the use, the fuel of the aircraft will change, so the situation under various oil levels must be measured.

Of course, in order to measure more accurately, this measurement is more troublesome, first fill up the oil and start the measurement, the result is still unsurprising, and the weight distribution is still no problem. There are a total of 14 fuel tanks in this fighter, and one of them is a consumption tank, and during the flight of the aircraft, the oil in the fuel tank is not directly extracted, but the oil in the other fuel tanks must be pumped into the consumption tank before it will be used.

This can ensure the stability of the fuel supply to the greatest extent, and at the same time ensure that the oil will not bring hidden dangers to the aircraft because of the maneuvering action, of course, the fuel supply is also a more troublesome thing, the oil pump needs to be controlled by the chip to pump the oil from other fuel tanks according to the order and quantity, and supply fuel to the consumption tank, and then it will be sent to the engine for combustion.

Of course, this design is not something that Li Zhao can come up with, it all comes from that drawing, but Li Zhao is now convinced by that drawing, the reason is very simple, judging from the current results, the drawing is very mature, although Li Zhao has modified it in order to adapt to the current situation, but obviously there is no problem.

Of course, this time is only a basic test, as long as there is no problem with the system, then in the manufacture of narrow aircraft, you can directly use the current design, as for the new improvement, that is a matter of the future, far from the present.

The next thing to carry out is the test of each system, first of all, the electronic system, directly use the power supply of the workshop to power the aircraft first, so that the situation of each part of the test can be relatively stable, including various instruments, radar, flight control, etc., have been tested, and the results obtained are of course also gratifying, obviously because this project is very important, everyone attaches great importance to it, and the components of each part have obviously been tested repeatedly.

Now assembled together, there is no problem, so the test tossed for more than an hour, began the most important ignition test, with the operation of the motor on the engine, the engine began to turn, the next is the ignition of the fuel, soon the engine is running, and with the successful ignition of the engine, everyone began to applaud, to be honest, today's test is relatively sloppy, but I didn't expect it to be so smooth.

With the successful ignition, the power supply on the aircraft was also provided by the aircraft itself, and then the various systems were tested again, and the results were also gratifying.

However, after some discussion, the plane stopped and began a new round of mass distribution testing, which will be measured once after each certain ratio of fuel consumption to ensure that the aircraft can be under the best mass distribution at all times, only in this way, the aircraft can be easier to control.

After the measurement was completed, the plane was slowly dragged to the runway, and everyone wanted to further test the aircraft's run, after all, this aircraft, after the test was completed today, it was necessary to carry out the static test, and it was impossible to carry out these tests in a short time, and now if there is no problem with the test, then there is no big problem with the static test, then the aircraft can

The construction of the second aircraft began, and at that time, it was time for a test flight.

After all, the static test of the aircraft, need to apply a certain force to each part, after such a test, whether the aircraft can still ensure the strength of the body, no one knows, after all, when the limit of the force, there will generally be deformation, at that time the aircraft can not be guaranteed integrity is not known.
