Wei Hongkun's actions frightened the people around him, and countless surprised eyes were turned to Wei Hongkun, but he didn't understand why it was so exciting that the old professor who was so sad just now was so sad. Others didn't know, but Wei Hongkun knew very well. He had been studying duck ~~the layout of wings for more than ten years.

For this reason, he thought of countless matching wing structures in order to find a suitable large sweep and small aspect ratio wing, so as to reduce the lift line slope, and finally achieve good maneuverability and excellent low-altitude driving while reducing supersonic resistance. In this way, the multi-tasking ability of the new fighter with a duck wing layout is revealed!

However, as the famous saying says, ideals are full, but reality is skinny. When Wei Hongkun was excited about the new changes brought by the wing layout, an invisible barrier made him stop and unable to move forward. This barrier is nothing else, but is the matching wing mechanism;

That is, you need to have high-altitude and high-speed flight capabilities, and take into account low-altitude and low-speed control. The choice of wings is particularly important. If there is a slight mistake, it will not only not reflect the advantages of the wing layout, but may also backfire, causing the entire aircraft to be scrapped. Because of this, Wei Hongkun has been pursuing the problem of matching the wing layout and wings for more than ten years and has made great progress. It seems that success is right in front of you. As long as you reach out and you can pick the ripe fruit.

But unexpectedly, the fruit of success seemed to be blocked by a thin layer of window paper, blocking his outstretched hand ruthlessly outside. Although it was close, it seemed to be thousands of miles apart. Because of this, it was ultimately impossible to obtain the precise data of the wing layout, so it was completely thrown into the cold palace at a certain research institute technical conference, becoming a pain that Wei Hongkun could not erase so far...

But I didn't expect that today, the transparent window paper made Lu Jiadong pierce the wings without tail three ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~

The wing layout technology that has accumulated for more than ten years burst out instantly, turning his somewhat bald brain into a computer that is running at high speed. The brain waves pass through the nerve veins as dense as a web. The rapid and shiny neural protrusions mobilize the data deep in memory again, like a trickle of streams, gathering into a vast ocean of digital, and quickly narrating the conclusions drawn in my mind with an irrepressible tone:

"The wingspan ratio is small, shock resistance is small, span and supersonic performance is high, and the focus change is balanced. Because the root chord is relatively long, it can obtain greater structural strength under thin thickness. After increasing the wing layout, the defects of the triangle wing layout can be alleviated, and the difficulty of triangular wing matching and poor low-speed performance are improved. It is precisely because the front wing is far away from the center, which can obtain a longer force arm, and is not affected by the wing airflow, and has high maneuvering efficiency, especially in low-altitude penetration situations, which can better achieve penetration tasks..."

Wei Hongkun became more excited and the more he spoke, the louder heavier he spoke. In the end, he simply bent down and picked up the pen and calculated it on paper. He was all experts in the aviation field, and perhaps he didn't react at the first time, but after listening to Wei Hongkun's excited words, he didn't understand what was going on.

So, the venue was surprised again. You should know that the reason why Wei Hongkun was so excited was that it was Lu Jiadong's words just now, with a wing layout with a tailless triangle. However, this simple sentence contained in the indescribable advanced technology, otherwise he would not have led a technical mate like Wei Hongkun to become so crazy.

If the person who said this is an expert and scholar in the field of aviation, the people present may sigh at the achievements of others, but they will never be shocked. But the person who says this view is a layman who is recognized by everyone as an outsider who does not understand aviation technology. However, it is this "outsider" who not only knows the most cutting-edge aviation technology, but also can awaken the old experts in the field with just a few words. Is this still an "outsider"? He is even more expert than an expert......

"I really didn't expect that Mr. Lu would have such advanced aviation technology!"

"I have said a long time ago that there are always some reasons to see Chief Yang staying so willingly. Now it seems that President Lu is indeed a knowledgeable person. He is much better than those laymen. If I were to stay, I would choose to stay!"

"Hey~~ You didn't say that just now, and you were muttering that Lu always had an amateur..."

"Yes? Did I say it? No, how do I remember what you said?"

.........

Similar sighs and discussions sounded silently in this simple conference room. A group of experts either whispered in pairs or whispered in a low voice. In short, there was nothing that was not bad at Lu Jiadong, and the look at Lu Jiadong also became more admirable and respectful.

The original fluctuating thoughts gradually calmed down between Lu Jiadong and Wei Hongkun's questions and answers, and a long-lost hope came into being in the hearts of everyone. Perhaps the multi-purpose fighter that Lu Jiadong just mentioned is not impossible to achieve; perhaps the so-called super fighter can be created in their hands; perhaps in the near future, a high-performance fighter that is comparable to the United States and the Soviet Union will soar between China's sea and air......

Looking at the changes in the emotions of people around him and the increasingly concentrated centripetal force, Yang Hongyi, who was sitting in the front row, couldn't help but nodded comfortably. The solemn expression of zombie also loosened at this moment, showing a stiff smile that was not easy to detect. In the moment when no one noticed, he gave Lu Jiadong a thumbs up, and that seemed to be saying:

"I knew you could do it, and you should do it too. If you have the skills and abilities, you should show it out, otherwise how can you convince the public?"

At this moment, Lu Jiadong only had a calm smile. Whether it was facing the admiring eyes of everyone, the admiration of Wei Hongkun, or the thumbs up secretly by Yang Hongyi, Lu Jiadong's response was all that gentle and indifferent smile. Perhaps in the eyes of the people in the audience, this was Lu Jiadong's modest and rigorous expression, but only Lu Jiadong himself knew that if he didn't pretend to be calm and calm, he might have to throw his face to his grandma's house in the next moment!

Because Lu Jiadong knew very well that there was only so much aviation ink in his stomach. As he often said when he joked with Yang Hongyi, he was a real aviation "theoretical school". In fact, he was indeed a "theoretical school". He could tell all the decrypted aviation theories that were circulated in later generations.

The general idea can be explained clearly, but if we go to actual calculations and tests, it would be really dark. No matter what, he had never developed a combat aircraft. The reason why he pointed out the flaws in Wei Hongkun's paper in public was nothing more than to allow Wei Hongkun to transfer the pain of his wound being torn. After all, what he saw, thought and thought were technology.

Since the pain caused by technology, it is better to use technology to make up for it. I believe there is nothing that can heal the scar in Wei Hongkun's heart than this. In fact, it is true. Wei Hongkun was as excited as a child. As for the wound that was accidentally torn by him, he probably had already been thrown out of the sky. However, Lu Jiadong took some risks when doing this. After all, he only knows so much about duck wing layout and tailless triangle.

If Wei Hongkun asked a few questions in depth, even if he didn't reveal his feelings, he would definitely be incoherent. By then, the wound would probably be worse than healing. Fortunately, Wei Hongkun did not ask any more. At least the technically difficult words did not act as a stepping stone to him. This made Lu Jiadong very glad and very lucky...

However, just as Lu Jiadong was secretly happy that his "scheme" had succeeded, his heart suddenly stumbled into his throat, because Wei Hongkun, not far away, suddenly shook his head and muttered inadequately: "No, no...", then raised his head, looked at Lu Jiadong in confusion, and questioned without saying a word:

"Since the main structure is determined, what should we do with the engine? Do we have a suitable aircraft engine?"

Hearing this, the aviation experts present couldn't help but become solemn again, but Lu Jiadong breathed a sigh of relief. As long as he stopped asking about advanced aviation technology, such a general direction had been planned a few years ago. So Lu Jiadong cleared his throat and said calmly and firmly:

"We don't have a large thrust engine yet, but we still have medium thrust. As early as two years ago, we introduced the complete production line and manufacturing process of Spey engines from the UK. Now the Northwest Power Plant has initial production capacity,"

"How to implement the radar?" Wei Hongkun continued to ask.

"A year ago, we obtained the an/awg-9 pulse Doppler radar on the Iranian F-14 fighter from a special channel and completed the source code cracking. The Central Plains Electronic Radar Institute has mastered all the core technologies. Based on this, it should not be difficult to develop a high-performance airborne radar that can be used to air and has the ability to shoot downwards and has the ability to shoot downwards. "

"What should I do with the control system of the aircraft? Although the wing layout has many advantages, its disadvantages are also obvious. One of them is that it cannot use the mechanical-hydraulic control system currently used in China, but must use line-transfer control. We are blank in this regard!"

"We can rest assured that we have already cooperated with France in this regard. Their latest line-transmission control and flight control software and flight control data have been provided to us as an important project for technical exchange. You should know that France is a technological pioneer in the field of wing layout and tailless triangles. Their control system and software programming are of great reference significance to us!"

Wei Hongkun widened his eyes and exclaimed incredibly: "Really!"
