For Li Zhao's insistence, Su's father agreed, but he was quite concerned about his safety, and it was estimated that when the time came to test, he would definitely be present, and as long as Li Zhao had any dangerous moves, he would definitely stop it, but Li Zhao also knew that the gentleman did not stand under the dangerous wall, and he would be very careful.

In this way, the assembly was carried out as scheduled, Li Zhao was also gambling this time, after all, the aircraft that was ready to be engaged in this time had too much helplessness, the first time was very tight, Li Zhao hoped to complete the first flight before the advent of the special period, and the second lack of test equipment, although the ground interview platform, die forging machine, five-axis machine tool, etc. have been made, even if the wind tunnel is estimated to be built at the end of the year, but there are still many things that are lacking.

For example, there is really no air test platform for the engine, as for the test platform for the turbojet engine, first of all, Li Zhao didn't know if there was one, and he didn't ask at all. Even if there is, it is not suitable, after all, Li Zhao made this turbofan engine has a huge difference in weight and thrust, and the platform is not suitable for testing when it is tested, even if it wants to be transformed, there is no suitable platform.

If this test is not successful, then Li Zhao can only go back and carry out the test step by step, which also means that the date when Li Zhao wants to quickly realize the first flight of the aircraft will be extended indefinitely. Of course, the follow-up operation tests of each part are not undone, after all, if these tests are not carried out, the follow-up improvements will not be able to start.

But the current situation is that Li Zhao does not have so much time to wait, and he will complete his first flight in the first half of the next year at the latest. If it is delayed too long, then it is very likely that the project will be delayed, and just like that, the assembly began, Li Zhao is experienced in this area, but the most important thing for him now is to train personnel.

Said that he had experience, it could be regarded as lifting him, after all, he had assembled one, and that time it was still a joke, so he was also a newcomer to assembling him, but he knew the engine well, and all the steps of engine assembly had already been completed in his mind, and now it was just practice.

After all, for this complex engine, it is difficult to realize automatic assembly, there are too many parts, and the use of machine assembly will also bring many problems, such as rubbing, etc., once it appears, it is basically necessary to replace the corresponding parts, and even scrap, the use of manual labor does not need to care too much, and it also takes time to train a qualified assembly team.

With the passage of time, on Monday, July 27, after more than ten days of teaching and assembly, the first engine was finally completed, and looking at the five-meter-long big guy fixed on the test bench, Li Zhao was very worried. Since I don't know what the results of today's test will be, there are only a few people in the factory who came today, of course, there is Su's father, followed by Master Zhang, then there is Brother Su Ya, and then there are Li Zhao and the people from the project team.

Today's test run is very low-key, and for the sake of safety, Li Zhao almost has to take a telescope to start watching the test process, but the preparation is sufficient, the display tables of various sensors are connected here, Li Zhao can easily see the thrust data, speed, temperature of each part and so on. ….

With the completion of everyone's inspection, under Li Zhao's order, the engine was energized, the starting motor drove the engine to rotate, and when the speed reached the starting requirements, the fuel injection and ignition began, and in this process, everyone also paid attention to the operation of the engine, for fear of any accidents. Of course, the number of revolutions is still very low, and the motor drives the engine to run many times, of course, no problems are found, and the next test will be carried out.

The start of the turbofan engine is actually more troublesome, direct fuel injection ignition can not drive the engine to rotate, peers need to jet the engine or have a special motor to drive to reach the speed of starting, and Li Zhao here, obviously unwilling to use jet start, and itself is electric start. However, it is also necessary to install a generator for starting the aircraft, which can be regarded as having its own shortcomings.

As the engine started, everyone became nervous, including Li Zhao, at this time, Master Zhang was estimated to be the most relaxed, looking at the nervous Li Zhao and Father Su, and said, "What are you nervous, isn't it millions? Our factory is not short of this kind of funds, and the two of you will be tight for this point

Zhang Qi, when testing tanks at that time, Li Zhao, you were going to directly blow up the tanks worth three million, and this is only a million."

Li Zhao listened to Master Zhang's words, and said angrily: "How can that be the same as this, that is basically not a big problem, blow it up, mainly to test the armor ability." And the difficulty of this is incomparable to the tank, let's talk about the speed, the maximum speed of this engine is tens of thousands of revolutions per minute, which is ten times that of the tank engine, can this be the same? And if something goes wrong this time, it will be delayed for a long time."

Yes, if there is a major problem in this test, then it will have to be tested separately, and it may require very detailed research, knowing that this engine is tens of thousands of parts, even if it is a twelve-cylinder turbocharged engine, there are only so many parts, there is no comparison at all. And if the problem is not big, it will be the best thing, even if the service life is relatively short, only a few hundred hours, it can be studied and solved.

Now the most feared thing is to have a direct problem, such as a slight acceleration, there will be an abnormal noise, in that case, the problem will be big, and there may be a lot of problems that need to be solved by Li Zhao. Of course, on the first day of ignition, Li Zhao couldn't accelerate, so he ran at a speed close to the lowest speed for an hour, ready to disassemble and check it first. Of course, this disassembly will not be disassembled into individual parts, but will be disassembled again after several parts are inspected without problems.

At this time, Master Zhang asked, "Is this the end?" I don't seem to hear anything wrong, I've seen planes in the military region, and the sound is not much different from this, why did it stop? We are not short of oil, I remember that thousands of tons were just shipped back a few days ago, is it because the superiors have a request that we are not allowed to use too much?"

For Master Zhang's question, Li Zhao is also helpless, he doesn't understand technology, and now in this situation, it is just that the ignition is successful, and it has been running at low speed for a while, and I want to confirm the situation of the engine first, what are you talking about.

However, Li Zhao still wanted to explain, so he said: "Today's first ignition, we only conducted a low-speed test, and then we will dismantle it and check it first, and after confirming that there is no problem at all, we will carry out other ones." ….

Listening to Li Zhao's words, Master Zhang is no longer entangled, but ran to see the engine with great interest, today's test is considered a success, from the instrument, the speed, temperature are relatively normal, that is, the thrust reaches the value is relatively small, Li Zhao is not sure about this engine, so he does not dare to drive a very high speed at one time.

Seeing that Master Zhang went to see the engine, Li Zhao and Su's father said, "I plan to assemble the other one first, test it together, and produce three more at the same time, so that there are enough five units to test together, what do you think?"

If you want to complete the test car test as soon as possible, you can only throw money directly, under normal circumstances, you can directly take one for the test, and then study it carefully, and then make some improvements according to the test results, and then carry out the corresponding test, but Li Zhao obviously can't wait that long, if you test like that, then the test cycle is estimated to be at least three or five years, or even ten years, so isn't the daylily cold?

Father Su looked at Li Zhao at this time, and still couldn't understand why Li Zhao was so anxious, after all, while Li Zhao was talking about the difficulties, he had to increase the number of test machines, and then wanted to conduct tests on multiple lines at the same time.

At this time, Su's father asked: "Li Zhao, why are you in such a hurry about the plane, it is said that this aircraft is much more difficult than the tank, that is, the tank has been carried out for more than a year, and if you want to develop the aircraft, it will not take ten or eight years, even if it is three years or five years, it will be very fast, why are you in such a hurry?"

Seeing Father Su ask, Li Zhao had to give a convincing answer, so he said: "I don't know how long we have to have a good time, as far as my thoughts are concerned, it is likely that we will start to live a hard life in a year or two, and if we don't complete the plane as soon as possible, we may not have the funds to study it."

Seeing Li Zhao say this, Su's father also looked dignified, yes, Li Zhao has analyzed the problem of alloy steel exports, the current situation, it is difficult to guarantee when others will cancel the order, you must know that now the annual export order of three million tons has come down, but because of the arguments here, it means that it will take time to expand the scale of production, otherwise it will start to increase the supply now, and now the supply will be increased

The volume of goods is scheduled for September.

From next year, it will be guaranteed to supply three million tons to the other party every year, and there is no guarantee for this order, once the other party breaks the contract, then the blow will be very huge for the 998 factory, which will directly lead to the shelving of millions of tons of production capacity, and the loss will be at least hundreds of millions, and most of the annual research funds will disappear directly, and only hundreds of millions of research funds per year can be guaranteed, in this case, how can Li Zhao not be in a hurry?
