Chapter 1636: What a big "soil"

"Actually, you don't need to envy your classmate at all." Song Wenhua obviously guessed what he was thinking from the change in the expression on Yang Wei's face, and then, as if to prove that what he said was true, he handed it to Yang Wei A document said: "The Commission for Science, Technology and Industry for National Defense has already begun to demonstrate the performance parameters of the next-generation main fighter aircraft. The first formal demonstration meeting will also be held soon. This indicates that we may be in the near future. Ushering in the bidding for the next generation of main fighters, and this time, I want to give you this burden."
A sense of well-being that was trusted and recognized suddenly flooded into Yang Wei's heart. He couldn't help looking at Song Wenhua, who was already gray-haired, and called out: "Teacher..."
Song Wenhua ridiculed himself and wiped his wrinkled face and said: "Look, I'm so old, I can't always dominate this position and not leave, right? It was because the "No. 10 Project" did not end, how about me, I want to finish the last post steadily, so I haven't mentioned this matter with the above, but now that the ending work of "Project Ten" is going well, I, it's time to retire. It is time, the burden of the future will be handed over to young people of your generation to take over."
Yang Wei suddenly felt that his throat was blocked by something. He opened his mouth, but found that he couldn't say anything, so he called out again: "Teacher!"
Song Wenhua waved his hand and continued: "I'll talk about other things later, let's discuss the topic first. This time the next-generation main fighter aircraft bidding, we mainly have two opponents, one of which is naturally our old opponent Shengjing. , I guess, they will still compete with the further development plan of the three-wing K98 scheme. This plan has been pre-studied for a long time. You know the specific situation. The three-wing layout will help K98 gain more Large lift and better maneuverability, but this scheme obviously lacks consideration of radar stealth performance. This is its most critical weakness. From the results of our own research and demonstration combined with the technical route choice of the Americans, radar stealth, It should be the most important performance focus of the next generation of fighters. Therefore, I think that Shengjing's plan has obvious flaws. Compared with this, another competitor is more worthy of our vigilance."
Speaking of business affairs, Yang Wei also restrained his emotions. After thinking about it, he could not help but said with some worry: "Teacher, what you said is the same as my feeling. The technological development route chosen by Xijing coincides with ours. In terms of the situation, Xijing Institute’s "Flying Leopard II" plan also considers radar stealth as the first priority, and they have also adopted a large number of new technologies on this type of fighter, such as phased array radar, such as " Feihuo pushes the integrated flight control system, such as United Avionics and high-speed data link. With their accumulated experience on the "Flying Leopard" fighter, I think they are our biggest competitors."
There was a little lack of confidence in Yang Wei's words, but Song Wenhua smiled slightly and said: "But I feel that Xijing has a major oversight."
"Major negligence? What is it?"
"Our China has a vast land area and a sea area of ​​more than 3 million square kilometers. This determines that our main model fighter must have a larger range and carry ammunition. Therefore, we use double large thrust engines as the power system. The fighter jets of China are the most suitable for the needs of our military, and the double push fighters naturally have advantages in terms of power reserve and can obtain more powerful maneuverability-so our next-generation main fighters must be heavy double push fighters. , And Xijing Institute’s "Flying Leopard II" is just a mid-size fighter with double center thrusters. Although from the current design parameters, the size is only slightly smaller than the old "Flying Leopard", and the combat radius may not shrink much. However, its ammunition capacity and maneuverability will inevitably be affected and restricted. Unless the "Turbofan 12" can achieve a significant increase in thrust and thrust-to-weight ratio in the future, it will become an irreparable feature of the "Flying Leopard II" fighter. Major defects-and we all know the time and money needed to make these improvements to the first engine and the various technical difficulties that may be faced. Therefore, I think this defect is not technical, but route selection of."
Yang Wei thought for a while, and asked with some doubts: "Teacher, you are right. I also think that the double push is the standard for the power system of our next-generation fighter aircraft. But Xijing has this oversight. Teacher, don’t you? Do you think it’s weird? It’s obvious that Brother Tan has the most engine resources in his hands, except for the Raksha AL-31F used on our "J-10" and the unfinished "Taihang" on Shengjing. His domestic turbofan engines are all in his grasp. Even if the turbofan 15 engine led by the Gas Turbine Institute and Xihangfa has nothing to do in a short time, Xijing can at least adopt the "Qinling" as the first stage. Power, this engine is always a bit old, but it’s really reliable, but why didn’t they use it and instead used the "turbofan 12" mid-push?"
Hearing Yang Wei's question, Song Wenhua's mouth suddenly wore a playful smile, and his eyes became very strange. After a long silence, he said softly: "I think I should know why, but this conjecture It's so bizarre, so bizarre that I can't believe it."
"teacher?"
"Many years ago, before even the "No. 10 Project" was officially finalized, Zhenhua, who just went to study in the US, gave me two gifts.
Song Wenhua narrated softly, his hand was stroked on a transparent fighter plane model on the table, which was refracted by the sunlight coming in from the window, and the voice was a bit faint, "You are all familiar with one of them. The model I kept on the table. Later, the model became a reality and became the appearance of our "J-10". And Yang Wei, look at the intake part of this model, this mussel-like intake, until In the early 90s, I only saw the actual photos on foreign materials. The Americans installed it on an F16 for a test flight to test the performance of this new air inlet. After seeing the photo, I I finally made up my mind to adopt this brand new technology on our "J-10". Now after a series of tests, we all know that this DSI inlet can not only remove the boundary layer, but also achieve The effect of the traditional intake duct also simplifies the structure of the intake duct and greatly reduces the weight of this part. It is a very good design. Although the DSI part of the model on this model is wrong, the idea is very correct. In the early 1980s, how could a freshman who studied electronics know this?"
"Then you haven't asked Senior Brother Tan?" Yang Wei was also curious and couldn't help asking.
"Of course I am asking, but his answer is ambiguous, and you know, that kid, who runs the train with his mouth full, do you dare to believe what he said?"
This is another stubborn stubborn... Yang Wei smiled bitterly, and had to change the subject and continue to ask: "Teacher, you said that Brother Tan gave you two gifts, one of which is this "J-10" "The model, what about the other one?"
"The other one has been locked in the cabinet by me, but today, I will forward it to you."
While talking, Song Wenhua took out a bunch of keys and opened a cabinet door, took out a cardboard box from it, and then took out another thing from the cardboard box and put it on the table.
Actually, it's another model of an airplane!
When Yang Wei saw it for the first time, he couldn't help but blurt out and exclaimed: "It's such a big "soil"!"
