Of course, Li Zhao is entangled in these at the same time, but also to solve other problems, that is, the strength and toughness of some parts, in the case of 13,000 newtons, can only be used for five or six hundred hours to overhaul, the reason is that the processing technology of some parts is not suitable, the strength of parts, wear resistance and other properties are not up to standard, and there are many such parts.

For this situation, it can only be solved by optimizing the processing technology, of course, some parts still need to be redesigned, these are solved, Li Zhao estimates that the service life can be pushed up in a section, of course, this is just a way, in fact, there is one of the simplest ways, that is, to reduce the requirements, the thrust is set lower.

For example, one hundred and twenty-five thousand N, this thrust is a thrust commonly used by many engines in the future, and Li Zhao is not dissatisfied with this thrust, which is a range that can be considered. If the problem of other parts can be solved, and the thrust requirement can be reduced a little, then the service life is likely to be greatly improved.

However, Li Zhao is a little undecided about this, but the performance of the final engine does not need to be determined in such a hurry, and it can be determined when the final aircraft is mass-produced. The most important thing now is to see if we can solve the problem of the maximum temperature and other components, and there is no rush for anything else.

With the gradual scrapping of the first engines, many of the most parts of the engine have been figured out, which is very helpful for the subsequent process improvement and redesign, but this work is quite cumbersome.

And when Li Zhao was busy with work, the new school year also started, and with the start of school, Li Xing and Wang Jun, who were arranged in Lijia Village, were also sent by Li Zhao's eldest brother, and now Li Zhao's position is not low, and the factory has also allocated a car, but when Li Zhao saw the two, he couldn't believe his eyes, it was really too tanned for the two, Li Xing didn't care, but Wang Jun was also so tanned, it was a bit too much.

Wang Jun has been following Su Ya for a long time, and she has learned how to dress up, that is, the clothes of this era are relatively simple, otherwise there is not much difference from the more ordinary clothes after sixty years. It's just that this two months in the village really made Li Zhao not know what to say, when he went back, he was beautiful, and this time he came back was a little black girl, her face and arms were tanned.

Especially the arms, it is particularly obvious, the place where the sleeves are covered and the place that is not covered are completely two colors, seeing this situation, Su Ya couldn't help it at first, and asked, "Why are you so tanned?"

Seeing Su Ya ask her, Wang Jun was still happy and said, "It's so interesting to grow things in that greenhouse, I go to help every day, and it's like this for a long time, Li Xing is also tanned with me, darker than me."

Li Zhao said angrily at this time, "Can you be the same as him? He's a leather monkey, he's used to tanning, and you haven't seen him before, when I was in high school, his favorite thing to do in the summer vacation was to go to the ditch to fish, sometimes just splash the water out, a sun is half a day, can you compare with him?"

At this time, Li Xing was unhappy and said, "Second brother, why did you start exposing my shortcomings? It's the same as the fish I caught, you haven't eaten it, besides, we are doing the right thing this time, I have been in the village for free clinics, and I have helped deal with many heat strokes, Wang Jun has helped a lot, she has helped manage a lot of things in the village, and she has helped the eldest sister-in-law, and the sister-in-law is considered to have been taught by her."

Li Zhao was still a little surprised when he heard it, knowing that his sister-in-law was helping to do things, but he didn't expect this master to be Wang Jun, but thinking about it, it was really possible, after all, his sister-in-law's culture was not high, and it was really normal for Wang Jun to give an idea when he encountered problems, but they were a little too hard, think about the big summer, two months of sunburning, how dark it must be.

At this time, Wang Jun also said: "I'm okay, the people in the village are very good, I will also help, basically there is no heavy work for me to do, and this greenhouse is really interesting, I also learned a lot, I really don't know how you thought of this, second brother, the land can still be planted like this." In the first two days, some of the greens in the field have been harvested, with an average of 3,000 catties per mu, and the most important thing is that you can plant almost six stubbles, which is almost 20,000 catties per mu, and there are fish and mushrooms, which is really profitable."

When Li Zhao heard this, he couldn't help but ask, "The first crop has already been harvested?" It's about the same, more than 50 days, plus the time for raising seedlings, there are also more than 70 days, only about ten days later than the research institute. How are the fish surviving? I'm quite worried about this, after all, it's just starting such a large-scale fish farming, and if something goes wrong, it's a big problem, and I've been busy lately, so I haven't paid attention to it, but you two know better."

At this time, Wang Jun said: "The survival rate is quite high, and there are always people in the Agricultural Research Institute who conduct sampling and analysis every day, and they will adjust it according to the water quality.

Of course Li Zhao knows this, but he doesn't have time to pay attention to these at all, and now he is asking Wang Jun about the work of the Agricultural Research Institute, and now he seems to be doing it very seriously, so he said: "I've been very busy recently, and I don't have much time to pay attention to these. But if you're interested, you can check it out, it's more interesting here than in the village."

At this time, Su Ya also said, "Yes, we are relatively busy, we don't go much, you can go and see it at night, there will be red and blue lights at night, and there is a tropical plant greenhouse, you can also go shopping."

They obviously didn't know the situation here, and seeing that both of them had bright eyes, Li Zhao couldn't help but quip: "Yes, it is still a love mecca in the factory, and many couples will go over there on dates, it is just right for you two to go, and we can also sponsor you a camera, you can take a few photos."

Where can Wang Jun withstand Li Zhao's jokes, he said that he would go to see Li's mother, and ran away, Li Zhao looked at this situation, and it was also funny, but it was still very interesting to see this situation.

Seeing that Wang Jun was gone, Li Zhao also put away his joke thoughts, and inquired with Li Zhao about the situation in the village, now that there are such big changes in the village, Li Zhao needs to know the specific situation, so as to provide some reference for the management of the next factory, so Li Zhao asked directly: "How do you feel about staying in the village for almost two months this time?"

Seeing that Li Zhao became serious, Li Xing also put away his laughter and said, "If you feel it, the people in the village are much more cheerful than before, although they felt good in the past, they have never been as relaxed as now, and they have not worked as hard as they do now. Let's just say that in the past, if there was no eldest brother to take the lead in the work, many people in the village would be lazy, but now it is different, everyone is very hardworking, and those who like to be lazy in the past are not lazy much, otherwise why do you think Wang Jun and I would be so tanned?"

After hearing this, Li Zhao also understood, and then asked, "Then have you gone to other villages?" What is their situation, they are only engaged in ecological agriculture there, although the investment is not small, but it is not comparable to the village."

Li Xing thought for a while and said, "I don't know the specific situation, if you want to know more clearly, it's best to ask the eldest brother, but as far as the places I have been to the free clinic are concerned, they should be pretty good." They are different from our village, our village plus the time you started the experiment, until now, it has been seven or eight years, and it has only developed to this extent, they can be regarded as one step to the sky, at most two years, they can catch up with the time in the first six or seven years of us."

Li Zhao thinks about it, it really took seven or eight years for Lijia Village to have today's situation, and they only need two years from this year to next year to catch up with the previous six or seven years of Lijia Village, only the glass greenhouse is missing. It's just that the glass greenhouse is not ready to be built in a short period of time, one is that the demand for vegetables in the capital is not so big, and the second is that the investment is too large, and the factory needs to see if it can maintain the current profits.

Seeing that Li Zhao didn't speak, Li Xing said, "By the way, second brother, why don't the factories hold free clinics for each village? My eldest brother and I went to the villages below, and their health conditions are still quite worrying, and my experience is relatively lacking, but if I go to the free clinic, there are not many problems that can be solved."

When Li Zhao heard this, it was really like this, and he never thought of this, then Su Ya said: "It's really like this, we have been ignoring this, the affiliated hospital has actually been having free clinic activities, but we are targeting the streets near the factory, and most of the people living here are the families of our workers, and we really haven't considered the village."

When Li Zhao heard this, he said: "Recently, let's see when it is more appropriate, let's start free clinics for people in the village, I think September is more suitable, this will need to do relatively less farm work, this will be the most work is to mow the grass and deworm the field, in general, it is not very busy, of course, it can be put after the autumn sowing to the year before, the village under our name is not much, and the time should not be too much."

After Su Ya heard this, she also wrote down the matter, and she was responsible for these things.
