Obviously, the leader also knows what Li Zhao said, and after looking at this processing center for a while, the leader can only sigh, and he also knows that what Li Zhao said is the truth, and this estimate is a huge pit of spending money.

Continuing to look back, the leader asked, "This is a jet engine, why is it different from what we usually use?" We usually use only one layer, and there is no front and rear impeller, what are you? Li Zhao saw the leader asking, and explained: "What you usually see is a turbojet engine, this is a turbofan engine, compared with it, the front and rear impellers are added, as well as an outer duct, this engine has stronger thrust." ”

"Foreign studies have found that the slower and lower the temperature of the gas ejected by the turbojet, the higher the energy utilization rate, and the turbojet engine must increase the jet speed and combustion temperature if it wants to achieve greater thrust."

In order to solve this contradiction, you can add a tail impeller to the tail of the turbojet, so that the exhaust gas can drive the tail impeller, so as to use more energy. But this can also lead to problems, such as insufficient air intake, all of which transfer the energy absorbed by the tail to the front, driving the fan at the front to increase the air intake. This will cause the temperature of the turbojet duct to be too high, so an outer duct is added to cool down with high-speed air. ”

"This significantly reduces the speed and temperature of the tail jet, which improves energy efficiency. Of course, the internal temperature will also be very high, and the internal mechanical operation also needs to use lubricating oil, so the internal is cooled with lubricating oil, if the cooling efficiency is not reached, you can also burn a part of the lubricating oil, which is probably the principle. Seeing that the leader nodded, indicating that he probably understood Li Zhao's words, Li Zhao continued: "The length of this engine is five meters, the maximum diameter is 1.18 meters, and the thrust can theoretically reach more than 12,000 N, that is to say, if it is installed on the sixth master, if the fuselage strength is enough, a single engine can make the sixth master fly above Mach 2.5, of course, the sixth master can't use this kind of engine, after all, the fuselage is too small to fit." Saying that, Li Zhao took out the rough drawings of an aircraft and handed it to the leader, asking him to take a look at it first, and then speak.

Seeing that the leader looked at it for a while, Li Zhao said: "At this time, I probably designed an aircraft, and the rating I gave is a third-generation aircraft, with a maximum take-off weight of more than 35 tons, a maximum speed of more than Mach 2.2, and an estimated load of five to six tons of ammunition, a combat radius of 1,500 kilometers, and a practical ceiling of 20,000 meters. Li Zhao is actually worried now, without him, he has never made a real plane, originally planned to let Father Su and them make some real aircraft drawings to study and study first, and then design, but I didn't expect to be driven to the shelves now.

In the current situation, if you don't come up with a few shocking enough things, you can't convince people at all.

The aerodynamic layout of Li Zhao's aircraft is actually run by enthusiasts on the wind tunnel software, and the shape is somewhat similar to the F15, which is the best aerodynamic layout among all Li Zhao's drawings.

But if you want to zoom in on the parameters that Li Zhao said, there is still a long way to go, and Li Zhao doesn't know what it will look like in the end.

However, Li Zhao wanted to exert force in this regard, so he continued: "This aircraft will use fly-by-wire flight control and abandon hydraulic control. The development is divided into three steps, the first step is to fly, the first step will not be too many flight actions, the second step is to enrich the flight attitude, and the third step is to realize the digitization of the aircraft. ”

"The duration of this project will be about 20 years, and I was originally going to start the demonstration research after the research institute of the 998 factory was in place. Strive to achieve results within five years, that is, to complete the goal of flying in the first step, and to be able to complete simple control, which is a bit difficult to apply to actual combat estimates. ”

"After completing the second step in about ten years, after this step is completed, it basically has actual combat ability, and it should be able to have relatively strong actual combat ability. The three steps will be completed in 20 years, and by then it should be able to have all-round combat capability. However, the investment will be very large, and I don't know how much it will cost. I originally wanted to announce it after completing the first step, and there would be a lot of manpower needed at that time, but now there is no way, and the 998 factory will not be able to support it at all. "How much does it cost Li Zhao really doesn't know, Li Zhao hasn't really studied the aircraft, but he has a turbofan engine in his hand that he doesn't know the specific model, and he has a good aerodynamic layout.

But now the cost is obviously a big problem, let's just say to build an engine, Li Zhao remembers, at that time, the factory received more than 20 million people, this is because the one produced at that time is only a prototype, if it is really installed on the plane for use, it is estimated that it can run for 100 hours is considered very good.

After reading Li Zhao's drawings, the leader sighed again and said: "I have always heard that you are going to make a series of engines and cars, but I didn't expect you to be ready to do these, and those don't cost much money, even if your factory invests, it can't use up the profits given to you by your superiors." Therefore, some people propose to appropriately reduce the price of steel, I think the profit is still very considerable, there is no objection, and now the price has been determined, basically there is no possibility of changing. Li Zhao already knew that this was the result, and then said: "Leader, you only consider the cost of materials, at most the cost of equipment, but have you ever thought that the factories that provide us with electricity and raw materials need to treat the polluted environment, should not?" If you don't pay attention to it now, it doesn't mean that pollution doesn't exist, and we will need to treat it sooner or later, and then you will understand that the price we are selling now is at a loss. The leader didn't expect Li Zhao to talk about the environment, so he said: "This is not enough, right?" Li Zhao smiled and said: "Just wait and see, when will the rivers in the capital become stinky ditches, will the superiors pay attention to it?" When the time comes, you will know how much it will cost to govern, and this is only the capital, what if the whole country? Li Zhao didn't want to dwell too much on this matter, and continued;

"The latter are all drawings of the vehicle, mainly a series of engine drawings, which will not cost too much, and it is estimated that a few billions should be enough, unlike the previous ones, each of which may be tens of billions." At this time, the leader was already angry with Li Zhao and said: "In your mouth, billions are all small money? How much is that big money? Don't you know, our military spending is only a few billion yuan, and it's all small money in your mouth. Li Zhao was also angry, and directly replied: "The annual profit of our 998 factory is a lot of money, 20 billion yuan a year, and the reduced income in one year is enough for the army to use for two or three years." Let's see how much money you can approve for our factory every year, right? In addition, I am afraid that the construction projects in the factory will not be able to continue, and we also need to be funded by the superiors, and after the construction of these projects, our research funds will be even more insufficient. Seeing that Li Zhao had begun to show signs of anger, Su's father, who had not spoken, said at this time: "What do you say, Li Zhao, if you have any opinions, go back and tell me, you just need to report the matter here." Li Zhao also knew that it was a bit excessive, so he sat next to him and stopped talking, at this time Father Su said: "Leader, what do you think we are doing now?" Otherwise, Li Zhao's research will not be carried out, and we have these things in the 998 factory, which is enough for us to live a good life for ten or eight years, or these materials will be left here, how about you hand them over to other research institutions for research? All the profits in the factory should be handed over, and let's just do a good job of production. "Where did the leader not understand Su's father's thoughts at this time, and also knew that Su's father saw that he was unwilling to allocate funds to the 998 factory, so he directly took retreat as advance, and directly picked his son to quit.

At this time, Li Zhao also smiled, now at this time, he directly asked the leader for money, and he asked for more than ten or two billion yuan a year, and the leader was definitely unwilling to give it, but directly picking the child is the biggest bargaining chip, and we will guard the current factory in a big deal.

At this time, the leader said: "Your gap is too big, how can we have so much money for you in our department?" Besides, you still have more than a billion dollars a year, which is much better than most departments. None of the other research institutes have only a few million dollars, and the few may only be hundreds of thousands, but you already have a lot. Li Zhao saw that it was impossible to get support from the leader, so he gave up, and then said: "Then leader, let's do it, some of the drawings are civilian, I will take them back directly to the rolling mill, and we will not bring back the military part, do you think it is okay?" "Those parts of the military should be shelved now, anyway, these are all possible to start after the current machine tool manufacturing, let the research institute pre-research.

Later, I studied CNC machine tools, and if I really couldn't do it, it would be a big deal in the rolling mill. Li Zhao didn't care whether the leaders agreed or not, and directly pulled out a series of things prepared for the rolling mill and held them in his hands.

Then he looked at Father Su, and when he spoke, Father Su saw that Li Zhao seemed to him, and he also knew Li Zhao's thoughts and said: "Then we will go back first, and if there are any projects in the future, we will report directly, if there is money, we will study it, if the funds are insufficient, we will have nothing to do." ”
