After arranging all kinds of things, Li Zhao let everyone go about their own affairs, basically the work has been difficult to carry out in the past few days, many of these researchers who have come over need to move, most of them have not worked in the aircraft factory, and it will take them a few days to move, but after this move, there should be no need to move in a short time, and they will basically work here in the future.

Aircraft projects will be one after another, in a short period of time is twin engine and single engine these two models, but obviously the follow-up research is impossible to stop, Li Zhao estimates, before the emergence of a new generation of fighters, only double engine is estimated to be able to develop ten models in the follow-up, three to five years to launch an improved model, and then thirty to forty years later to develop a new generation of fighters, in short, the research project is very many.

After saying goodbye to these people, Li Zhao went directly to Su's father, he needed to continue to apply for materials and personnel, and after meeting, Li Zhao said: "Today, the aircraft research project team has been formed, and now we need to apply for some aircraft test pilots and at least one aircraft to come over, and the test pilots also need further training, and the current pilots are unlikely to be able to withstand the overload of our new aircraft, and they may be in trouble if they don't train."

After hearing this, Father Su said, "You tell me in detail, what you need, and I will apply for you as soon as possible."

Now that the project has advanced here, there is no possibility of retreat at all, you must know that this project has spent more than a billion, although the preliminary preparations, the results are very useful, but after all, it is the pre-position of this project, if the aircraft project cannot be carried out now, then the responsibility must still be carried, so as long as Li Zhao is in need, it must be fully supported, and now Su's father is also very anxious.

Li Zhao was not polite at this time, and said: "It is best to have one or more Mi-21s, this fighter is similar to ours in terms of maximum speed and flight altitude, but there is a big gap between the climb rate, maximum overload, maneuverability, radar, weight, etc.

After hearing this, Father Su smiled instead, and then said: "Now it's going to be cheaper Lao Zhang, he is in the army, these people are here, then the management must basically be handed over to him, and it is definitely inappropriate to stay in the Air Force, can't we train people with hard work, and the Air Force will transfer them directly after they take a fancy to them, right?"

After listening to this, Li Zhao said: "Now Uncle Zhang is going to raise his eyebrows, he has been complaining that he can't touch our good things, now it's okay, all the planes will pass through his hands first, I just don't know how he will feel when the plane finally flies away, but it is indeed more appropriate to put it there for him."

Although there are many retired personnel in the factory, the test pilots are obviously not retired personnel, not only are they not retired personnel, but they may be the handful with the highest technical level among all pilots, after all, the performance of the aircraft depends on their tests, and it is also on the premise that they do not understand the performance of the aircraft at all.

Father Su also smiled and said: "Let's not tell him about this first, let's build the training base first, and our test flight site also needs to arrange personnel and equipment, although it has been built, but because there are no aircraft, we have not installed equipment, let alone arranged personnel, it seems that we need to arrange it as soon as possible."

When the aircraft factory was under construction, the runway and the accusation center had already been built, but because there were no planes in the factory, the equipment of the accusation center was basically not installed, and now it is ready to station the aircraft and personnel, so it is obvious that the equipment and personnel need to be completed as soon as possible, and it needs to be done as soon as possible.

After hearing this, Li Zhao nodded and said: "Yes, especially the pilot training center, we must also speed up, we may also need to make a series of improvements to the equipment of the training center, the overload of the Mi 21 is only 6.5, and the overload of our aircraft will be nine, such an overload has higher requirements for the pilot, once the physical fitness is not up to standard, then the consequences will be fatal, and relevant training must be carried out first."

After listening to Li Zhao's words, Father Su also recorded Li Zhao's requirements and began to write a report, which were all things that needed to be handed in as soon as possible

The sooner you arrive, the better, especially in the future, you don't know how long it will take to train the right pilots, and you know that in 60 years, it will take a long time.

Future pilots, if they want to meet the standards of piloting a third-generation aircraft, the first is the arduous ground training and learning, after all qualified, they also need to carry out flight simulations, and only after passing can they go to the first six, after the first six is to change to fly higher education six, after the completion is to get off the troops, contact with real fighters, generally may start from the J-7, reach a certain flight time, and the physical value is up to standard, and finally complete the corresponding learning.

In this way, you can start to fly the third-generation aircraft, which takes a very long time, generally at least more than three years, and this is just the beginning, if you want to fly the third-generation aircraft, you still need to complete a series of training to be possible, and it may take more than five or six years to really become a qualified third-generation pilot.

And now the training center set up in the factory, obviously there is no simulator, so there will be more problems in the middle, and the exploration of aircraft performance will take longer, so you can only walk slowly step by step.

Farewell to Su's father, Li Zhao will be fine for the time being, he came directly to the engine group, continue the unfinished test, at this time is testing the third batch of engines, and now twenty-seven units have been manufactured, for the final result of the test, in fact, Li Zhao has been able to roughly know, in a short period of time, if there is no big improvement in the process, basically the performance can only be like this, after all, many things are hard indicators, and if they can't be reached, they can't be reached.

After coming here, looking at the ongoing test, Li Zhao also began to compare the data of the three rounds of tests, hoping to find a better way, for the current situation, it is basically impossible to improve the overall design of the engine, which takes a lot of time to complete, Li Zhao refers to this engine He does not know the specific model, but it must have been in service, but because the overall thrust is too small, Li Zhao directly improved.

After all, the original afterburner thrust is only one hundred and thirty thousand Newtons, and the thrust-to-weight ratio has not exceeded eight, which of course does not meet Li Zhao's requirements, so it must be improved, but now if you want Li Zhao to redesign an engine, when it is needed, it is at least one to two years to be possible, and the calculations required in the middle are too much, not to be completed in a short time, you must know that now under the maximum thrust, the thrust-to-weight ratio has reached 9.4.

Of course, if Li Zhao limits the thrust to the original level, then the service life can be greatly improved, Li Zhao tried, if the afterburner thrust is only one hundred and three, the maximum thrust is set at one hundred and one, then the first overhaul life, should be able to reach three thousand to four thousand hours, after all, one hundred and thirty thousand newtons, this engine can be used for six or seven hundred hours, one hundred and one cases, of course, the life is much longer.

In this case, only a small number of parts can be optimized, the rest is to find a way to improve the processing process, those parts that need to be optimized, mainly those parts that are easy to be damaged in high-speed operation, Li Zhao and the project team, now do the most thing, is to detect the cause of wear or damage of these components, have made some improvements, there are effects, but the effect is not significant, after all, the overall design of this engine is very perfect.

In the face of this situation, the best way Li Zhao can think of is to improve the processing technology of various components, such as fragile parts, and continue to enhance the strength of parts, such as enhancing the strength of the surface layer of parts.

In particular, the surface shot peening technology used in it, which is a better technology to enhance the surface in the future, the effect is still more significant after use, and the chrome plating treatment is a bit effective. It's just that Li Zhao doesn't know much about the coating, although he knows that there are wear-resistant and temperature-resistant coatings, but there is still no eyebrows, and the research institute in the factory is also conducting corresponding research, but it takes a lot of time.

Li Zhao also hopes that through a series of process treatment, the service life can be greatly improved, but there are too many processes that need to be tested, and Li Zhao estimates that it is unlikely to complete all the tests in a short time, such as the third batch of nine engines, in fact, each one

It's not the same anymore, and the intermediate process difference is still relatively large.

Judging from the current test results, if there is no big process improvement, after this batch of tests, only need to combine a series of excellent processes according to the test results, and then manufacture so many units for corresponding tests, you can first preliminarily finalize an engine, after all, according to the test, the final service life, it is estimated that there will be about 800 hours, if the thrust is limited, 1,000 hours is not a big problem.
