For the flight control system used by the aircraft, Li Zhao is very eager to use the fly-by-wire flight control, the reason is also very simple, the use of fly-by-wire flight control is light, but whether it can be completed is the biggest problem, Li Zhao very much hopes to complete the first flight of the aircraft next year, if the fly-by-wire flight control can not be done next year, then it must only be a mechanical flight control.

However, the thrust of the engine is large enough, and the focus is on it, for the engine that can reach 13,000 N without afterburner, the problem of increasing the weight is not big, Li Zhao estimates that no matter which flight control system is used, the final bomb load of 10 tons is not a problem, but the use of fly-by-wire flight control, the thrust-to-weight ratio can be larger.

Of course, there may be restrictions on the engine in the future, because if the thrust reaches this level, the service life is a little short, according to the results of the second round of tests, if it is this thrust, basically 600 hours should be the limit, if the thrust is reduced to about 120, it should be easy to break 1,000.

One hundred and twenty thousand N, the temperature before the turbine can be reduced a lot, and the damage to the engine can be reduced a lot, of course, it also depends on the follow-up research, after all, such a large thrust is too tempting, if the strength of the aircraft can pass the test, maybe this aircraft may also face the air-to-air missile, directly foot on the floor oil, two engines to reach three hundred and twenty thousand N thrust, directly out of Mach three, the missile may be thrown off.

It's just that now we need to find a better way to solve the problem of engine life, after all, five or six hundred hours is too little, this kind of engine up to more than one million, if you change two a year, then the cost of using the aircraft is too high, but it is difficult to find a very good way, which may take a long time.

But now Li Zhao's drawings are completed, but he didn't plan to take them out directly a year ago, and now take them out, so basically Li Zhao just wants to have a good year, and the period of time that he just took out will definitely be the busiest time, set up a complete project team, and then distribute the development tasks, and finally discuss the design details of each part as needed.

Of course, Li Zhao doesn't take out the design drawings now, and he is not lazy, he has now started to draw the single-shot version, relatively speaking, the cost of using the single-shot version will be lower, and the cost will be much lower, maybe it will be easier to be purchased, the current 998 factory, the order in the military industry is too small, if it is not for the relatively low salary of personnel, it is possible to lose money, and the loss will be a very serious thing for a factory.

Li Zhao has achievements here, and there are other achievements in the factory, one of the most important achievements is that the design of the 5,000-square-meter blast furnace has also been completed. It's just that the blast furnace design is completed, but the efficiency is definitely lower than in the future, whether it is the degree of automation or various auxiliary facilities and equipment, there is no way to compare with the future.

It's just that this design is completed, but Li Zhao doesn't know whether to build in the rolling mill anymore, so Li Zhao found Su's father, and after handing over the project report to Su's father, Li Zhao said: "This project, I feel that we shouldn't build it in the rolling mill again, now the raw material supply of the rolling mill is already very tight, if this project is arranged in the rolling mill again, we will face greater pressure on the transportation of raw materials, which is not conducive to production." ….

"In addition to the problem of transporting raw materials, there is also the problem of pollution, which we must also consider, after all, this is the capital, and it is impossible for the capital to keep a highly polluting industry like ours all the time. And there is a bigger question, that is, where should our iron ore come from, our current iron ore supply is almost the limit, and two 5,000 square meters of blast furnaces basically have a production capacity of 8 million tons."

Li Zhao knows what the future holds, although countries in the world do not pay much attention to the problem of pollution, even if it is a developed country, it will only pay attention to it in more than ten years, but for Li Zhao, it is very necessary to take precautions. Now two 3,000 square meters are okay, but two more 5,000 square meters, then it is a bit too much, and this is also very unfavorable for future development, once the large-scale relocation, the loss of production is too great.

After listening to Li Zhao's words, Father Su thought about it, his thoughts were still very different from Li Zhao, although he was very discerning, but the times

's limitation is a hard injury, but since Li Zhao said it, then there must be Li Zhao's reason, so he asked, "Then where do you think it's best to build?" It's too far away, it's definitely not going to work, it's impossible to manage."

Li Zhao actually has a headache, after the 5,000-square-meter blast furnace, the biggest problem is actually the source of ore, now to provide iron ore to the factory of the mine, the production capacity is limited, and the potential is also very limited, this era is not like the future, can import a large number of iron ore from abroad, after two 5,000-square-meter blast furnaces, the biggest problem may be the problem of insufficient supply of iron ore, which Li Zhao does not know how to solve.

Li Zhao didn't know about this situation, so he had to say: "I don't know where to build it, as long as there are large iron mines in China, there are basically steel mills around, which are smaller in scale compared to us, and now many factories are also surprised to prepare for the construction of new blast furnaces, and our converters have been shipped, so it is very difficult to find a better iron mine to build a factory in China."

"Now the only way out may be to import iron ore, if this is the case, then Shanghai is definitely the best place, then shipping is more convenient, the radiation area is also large enough, once a large steel plant is built, and then part of the alloy steel production capacity is transferred to the vicinity, then it will be more convenient than shipping from the capital."

After hearing this, Su's father said: "That's the reason, but it's obviously too far away, once the factory is built there, then after it is completed, it basically has nothing to do with our 998 factory, and the superiors directly send someone to take over, where do you still need our 998 factory management, and maybe, we need to divide some people over."

Li Zhao thought about it, this is the truth, such an operation, it is impossible to say that the 998 factory can hurt the bones, after all, such a large-scale factory, the demand for workers and various technical personnel will be very huge.

In particular, in the production of alloy steel, it is even more problematic, for the sake of secrecy, it is impossible to say that a group of people will go directly from the 998 Factory, and finally a part of the troops will be transferred from the vicinity to protect it, and at the same time, it may be necessary for the research institute to send some people to the new research institute, and in this case, it will be a great weakening of the 998 Factory. ….

At this time, Su's father couldn't sit still, and began to pace back and forth in the office, trying to find a way to get the best of both worlds, and said after a while: "We have also invested heavily in iron ore exploration and mining in the past two years, and now we have explored several rich ores near the original mining area, and now the proven reserves have reached hundreds of millions of tons, as long as we vigorously develop the mining industry now, we can alleviate the problem of iron ore shortage, as for imports, it is estimated that it is more difficult."

After Li Zhao heard this, although he thought about importing iron ore, but in the current situation, he could only do this, but Li Zhao then asked, "Then where should we build the new steel mill next?"

Father Su thought for a moment and asked, "How about building near the iron mine?" That would greatly reduce the cost of transportation."

Li Zhao was also stunned when he heard it, the good guy lifted a stone and hit his own feet, where can a steel plant be built, the earthquake more than ten years later is there, built there, it is better to build it directly in the capital, built in the capital, more than 100 kilometers away, although the earthquake is strong, but the destructive power is not so serious, directly build it, isn't it looking for death? And obviously there is no way to tell Su's father that there will be an earthquake there in more than ten years.

But now this situation can only be the next second, there is definitely not good, Li Zhao thought for a while and said: "It's good there, but the transportation is not convenient, we need to transport coal over, and at the same time, we also need to transport the steel produced there, either by railway or to Jinmen first, and then by shipping to the south, so it is better to build it directly in Jinmen, so that the coal transportation does not have to go through the capital, go directly to Jinmen."

Li Zhaoxin said that although it is slightly closer to the capital, it is better than building directly on the earthquake point, and the earthquake may be stronger, but as long as the construction is carried out, the requirements will be raised, and then try to arrange those days as the planned maintenance time, then the problem will be much smaller, after all, it is a larger blast furnace, and when it is built, the requirements are higher.

After hearing Li Zhao say that it was okay to transport coal without going to the capital, Su's father was directly moved, this is true, and he wanted to transport coal to the mining area

You must go to the capital, just with the current business of transportation in the capital, it is really not built in the capital, you can just avoid the busiest transportation point here in the capital, which can also reduce the pressure of transportation in the capital.

Su's father said at this time: "It's a better idea, although it is far away, but the shipping there is more developed, and the steel can be transported directly to the south through shipping, which is much lower than the cost of all trains, and at the same time, it can also separate the trains that transport coal and reduce the freight pressure in the capital, which is better."
