Li Zhao didn't dare to take this credit on himself, if he did this, would he not be able to do the work of the Agricultural Research Institute in the future? After all, the main people who do things now are the people from the Agricultural Research Institute, and Li Zhao has at most come up with a few ideas and just use his mouth, so Li Zhao needs to share this credit as much as possible, but now it has reached an impasse, and the leader keeps giving credit to Li Zhao, and Li Zhao is constantly refusing to accept it.

At this time, the leaders of the military industrial system couldn't stand it anymore, so they said: "Li Zhao, you don't have to shirk, you have all the credit, the efforts of everyone in the research institute can be seen by the superiors, and your credit, the superiors will not forget, after all, the overall planning is all from you, and the initial practical application was also carried out by you, and now there are just a few hundred more people to help with the research, so everyone is rewarded, it should be yours, you don't need to shirk."

At this time, Division Commander Zhang also came out to play a round and said: "This merit will be handed over to the superiors to evaluate, we are mainly looking at the fighter drawings today, why don't we go to the study now, I don't know how much has been completed?"

Li Zhao also said at this time: "I almost forgot about the business, let's go and take a look together, now I have only completed the general layout drawings, and about one-third of the engine drawings, and it is still a long time before it is completely completed." The project is so complex, there are more than 20,000 parts for the engine alone, and I estimate that I will not be able to complete the engine drawings until the end of next year, and then probably all the drawings will be completed the year after that, and the first prototype will be produced in '65."

At this time, Master Zhang asked, "Why is it taking so long? Wouldn't it take four years before and after, which doesn't match your style, I think you usually make other drawings very quickly, isn't it? Even the die forging machine was completed in just half a year."

Li Zhao saw that Division Commander Zhang asked this, and wanted to give him a thumbs up, Li Zhao replied: "The reason is very simple, the fighter is too difficult, let's just say that this engine is based on the turbojet engine, and another layer of duct is added, and then several levels of turbines are added, and the overall complexity is several levels higher than that of the turbojet.

This speed is very fast, after all, only Li Zhao himself can draw now, and others have no way to understand Li Zhao's design now, after all, they have never participated in such a design. Moreover, this project is an absolutely confidential project, and if production really starts in the future, a new factory will be set up, so Li Zhao will not take out the drawings casually before selecting the corresponding specialized personnel.

Moreover, which country does not develop an aircraft in ten years, and there is another country that directly spent 40 years in order to develop a third-generation aircraft, and in the end it was not considered a success. Of course, these words must not be said, Li Zhao can only say the difficulty of his side, let the leaders compare themselves with the current fighters, and they will be able to understand in their hearts that Li Zhao's is not easy.

Of course, this is also related to the fact that although Li Zhao had made engines before, he had not really tested them, and he just went to see them at that time, and the specific performance was only heard to be good. Therefore, after the engine is manufactured, it needs to be tested to see if it can meet the design requirements, if it can be achieved, then it is good to say, if it cannot be reached, it will be troublesome, just the engine may require Li Zhao to spend a lot of time to modify, of course, Li Zhao is still quite confident. ….

Despite this, Li Zhao doesn't dare to say this now, but now he wants his superiors to agree to invest in the construction of die forging machines, if he says this, his superiors will probably hesitate, after all, the investment amount is too high.

When he came to the study, Li Zhao went to the safe and took out the drawings, these drawings were too many, Li Zhao had already done binding, basically fifty sheets, Li Zhao hugged five or six times before he finished hugging, it was too much, and when the safe was installed, the installation was big enough, otherwise it couldn't be put down.

Li Zhao worked very hard to hold these drawings, but it is estimated that they were taken for nothing, and the leaders should not be able to understand them. Of course, the reason why Li Zhao took out so much was also to show his superiors his workload, otherwise the leaders would not know how much he had done, and the drawings he brought out were the best evidence and had strong convincing power.

At this time, Li Zhao said: "These drawings are, about more than 3,000, almost the same

It's about six or seven thousand parts, and it's estimated that 10 percent of the total number of drawings will be there, and the total number of parts will be estimated to be 80,000 or 90,000."

After listening to Li Zhao's words, everyone stopped talking, there are too many parts, Li Zhao only knows it in his heart now, but if the design is not finally completed, he doesn't know how many parts there will be, but it is estimated that there should be eighty or ninety thousand, after all, the two engines account for about forty-five thousand parts.

Master Zhang asked, "Then why don't you let the people from the Mechanical Research Institute get involved, isn't that faster?"

Li Zhao was speechless at this time, and Father Su said at this time, "Lao Zhang, what are you talking about? This project is a confidential project, you didn't see it at today's meeting, Li Zhao didn't dare to say it directly, we don't complete the special manufacturing plant, after forming a special team, these drawings will not be put in the factory, here may be safer than the factory."

Master Zhang didn't speak at this time, he just wanted to be faster, but he ignored the safety issue, but put it in Li Zhao's house, it would indeed be safer than putting it in the factory, Li Zhao's office in the factory, there are too many kinds of drawings, and there are many people receiving every day, all of which are about the discussion and review of drawings in all aspects, and there are far more people in his office than in his house, and generally do not think that Li Zhao will put the drawings at home.

Speaking of this, Li Zhao also took out the overall drawings and showed them to everyone, this is a display map of the fighter from all angles, mainly showing the back, belly, front view, side view, and rear view, which can be regarded as showing the overall situation of the fighter, which can make people understand the overall situation of the aircraft at a glance.

As you can see, there are some data marked above, the length of the aircraft is 20 meters, the wingspan is 14 meters, the height of the aircraft is 5.6 meters, the wing area is 60.6 square meters, the dead weight is 13.9 tons, the maximum take-off weight is 30 tons, the range is more than 4,000 kilometers, the combat radius is 1,500 kilometers, the practical ceiling is 20,000 meters, and the maximum flight speed is not less than Mach 2.2.

Looking at the data marked on the drawings, several people looking at the drawings are excited, this fighter is really not what they can imagine, compared with the existing fighters, it is too big, but the length is five meters longer than the current fighter, and the wingspan is also five meters wider, it is really not comparable to the fighters of this era, not to mention the advantages of speed, ceiling, range, load and so on, how can it be that the current fighter can be compared. ….

Of course, this is only a preliminary plan, Li Zhao doesn't know what the specific performance will be, after all, the engine has not yet come out, and I don't know if the engine can meet the design requirements, after all, if you want this fighter to fly to a speed of Mach 2.2, the thrust of the two engines needs to be at least 25,000 N, and the engine power can be excessive, but it must not be able to pull the crotch, otherwise this aircraft will be a little unsatisfactory.

Li Zhao also said at this time: "This aircraft is a twin-engine, tandem two-seater, double-tail, swept wing conventional layout, using two sides of the air intake. Now because our electronic system may be relatively poor, it may be difficult for one person to control the aircraft, so I have adopted a two-seat mode, so that one person can operate the aircraft and one person can operate the weapons, in this case, it should be able to better ensure the combat power of the aircraft."

However, Li Zhao also has something not to say, that is, he is ready to directly engage in fly-by-wire flight control, and he may encounter more difficulties at that time, but he feels that the early models do not engage in so many bells and whistles maneuvering, and should be able to achieve it, after all, the hydraulic mechanical control system is too cumbersome, Li Zhao is afraid that the thrust of the aircraft engine is not up to standard, and when the load is not up to standard, it will give him a headache, but he doesn't know whether the simple operation at the beginning can be successfully completed.

Of course, Li Zhao will also make preparations with both hands, if the electronic research institute can't finish talking by then, then Li Zhao will also directly change to the hydraulic mechanical control system, after all, although it is bulky, but it is mature, it is really not good and can only make do with it, but Li Zhao still hopes to directly realize the fly-by-wire flight control system, and it is okay to pull the crossing point in the early stage.

After all, the direction of future development at this time, as long as the initial goal of flying up can be successfully completed, there is no problem at all, after all, this fighter has huge room for improvement in the future, as long as the problem of whether there is or without can be solved, Li Zhao believes that each aircraft factory can finally play with him, and the future upgrade is not a problem at all, the biggest problem is to have a platform first.

At this time, the leader of the military industrial system said: "Okay, if this fighter can be put into service smoothly, our safety will be greatly guaranteed, and this fighter is much more advanced than other countries."

Li Zhao said at this time: "It is estimated that there is still a long way to go if I want to enter service, and I can't do anything about the various systems that are matched, such as various weapons, which I have never been exposed to at all. Then there are electronic systems, and I am still in the stage of knowing how to use them, and it is difficult for me to develop electronic related systems."
