Wei Hongkun's actions frightened the people around him, and countless surprised eyes turned on Wei Hongkun, but they didn't understand why, they could make the old professor who was gloomy just now excited like this, others didn't know, but Wei Hongkun knew very well, you must know that he has been studying the layout of duck~~ wings for more than ten years.

To this end, he thought of countless matching wing structures, in order to find a suitable wing with a large sweep and small aspect ratio, so as to reduce the slope of the lift line, and finally achieve a good maneuverability and excellent low-altitude handling while reducing supersonic drag, so that the multi-mission ability of the new fighter with a duck~~ wing layout is revealed!

However, as the wise saying goes, the ideal is very plump, but the reality is very skinny, when Wei Hongkun was excited about the new changes brought about by the duck~~ wing layout, an invisible barrier made him stop there, and it was difficult to move an inch, and this barrier was nothing else, it was the matching wing mechanism;

That is, to have high-altitude and high-speed flight ability, but also to take into account the low-altitude and low-speed control, the choice of the wing is particularly important, a slight difference in the pool, not only does not reflect the advantages of the duck ~ ~ wing layout, but also may be counterproductive, resulting in the scrapping of the entire aircraft, because of this, Wei Hongkun has been diligently studying the duck ~ ~ wing layout and wing matching problem for more than ten years, and has made great progress, it seems that success is in front of you, as long as you reach out to explore, you can pick the ripe fruit.

Unexpectedly, the fruit of success was as if it was blocked by a thin layer of window paper, and his outstretched hand was ruthlessly blocked outside, although it was close at hand, it seemed to be thousands of miles apart, and because of this, it was finally impossible to get accurate data on the layout of the duck~~ wings, so that at a certain research institute technical conference, it was completely thrown into the cold palace, which became a pain that Wei Hongkun has been indelible so far

It's just that I didn't expect that today, that layer of transparent window paper, but let Lu Jiadong pierce a sentence without a tail three ~~ horn ~~ wings, yes, it is indeed pierced, and it is a big hole, he has tried edge strip wings, double triangle ~~ wings, and swept wings, but he never thought of tailless three ~~ horn ~~ wings;

The duck~~ wing layout technology accumulated for more than ten years burst out in an instant, making his somewhat bald brain become a high-speed computer, brain waves travel through the dense neural veins like a spider's web, and the rapid shining neurites mobilize the data from the depths of memory again, like a trickling stream, gathering into a vast digital ocean, and with an irrepressible excited tone, the conclusions drawn in the mind are quickly narrated:

"The tailless three~~angle~~ wing span aspect ratio is small, the shock wave resistance is small, the trans\ supersonic performance is high, and the focus change is balanced; and because the root chord is relatively long, it can obtain greater structural strength in the case of thin thickness, and after increasing the duck ~~ wing layout, it can alleviate the defects of the triangle~~ wing layout and improve the triangle~~The trim of the wing is difficult and the low-speed performance is poor, because the front wing is far away from the center to get a longer force arm, and it is not affected by the wing airflow, and the maneuvering efficiency is higher, especially in the case of low-altitude penetration, the penetration task can be better realized."

The more Wei Hongkun spoke, the more excited he became, the louder he became, and in the end, he simply leaned down, while talking, he picked up a pen and performed it on paper, all the experts present were experts in the field of aviation, maybe he didn't react at the first time, but after listening to Wei Hongkun's excited words like a broken thought, he didn't understand what was going on.

So, the venue was surprised again, you must know that the reason why Wei Hongkun is so excited is that Lu Jiadong just said that the duck~~ wing layout with tailless triangle~~ wings, and this simple sentence contains indescribable advanced technology, otherwise he would not have led a technical nerd like Wei Hongkun to become so crazy.

If the person who said this sentence is an expert and scholar in the field of aviation, the people present may feel the achievements of others, but they will never be shocked beyond measure, but the person who said this point of view is recognized by the big guys as a layman who does not understand aviation technology, but it is this "layman" who not only knows the most cutting-edge aviation technology, but also can wake up the old experts in the field with just a few words

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

"I said a long time ago, there are always some reasons for seeing Mr. Yang stay so willingly, now it seems that Mr. Lu is indeed a knowledgeable person, much stronger than those laymen, if it were me, I would choose to stay!"

"Hey~~ You didn't say that just now, and you muttered that Lu is always a layman"

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

Similar exclamations and discussions sounded silently in this humble conference room, and a group of experts whispered in pairs or twos, or muttered quietly together, all in all, there was no one who did not give a thumbs up to Lu Jiadong, and the eyes that looked at Lu Jiadong also became admiration and respect.

The original fluctuating thinking gradually calmed down between Lu Jiadong and Wei Hongkun's questions and answers, and then a long-lost hope came into being in the hearts of everyone; perhaps the multi-role fighter that Lu Jiadong just mentioned was not impossible to realize; perhaps in their hands they could really create a so-called super fighter; or perhaps in the near future, a high-performance fighter comparable to the United States and the Soviet Union would soar between China's sea and air

Looking at the changes in the emotions of the people around him, as well as the more and more condensed centripetal force, Yang Hongyi, who was sitting in the front row, couldn't help but nod comfortingly, and his zombie-like solemn expression also loosened at this moment, revealing a stiff smile that was not easy to detect, and at the moment when no one was paying attention, he gave Lu Jiadong a thumbs up, which seemed to say:

"I know that you can do it, and you should be like this, if you have the skills and skills, you should show it, otherwise how can you convince the public?"

At this moment, Lu Jiadong is just wearing an indifferent smile, whether it is facing everyone's admiring eyes, or Wei Hongkun's adoring look, or Yang Hongyi's secretly thumbs up, Lu Jiadong's response is without exception that gentle and indifferent smile, perhaps in the eyes of the audience, this is Lu Jiadong's modest and rigorous performance, but only Lu Jiadong himself knows that if he doesn't pretend to be calm and calm the scene, he may have to lose his face to his grandmother's house in the next moment!

Because Lu Jiadong knows very well that there is so much aviation ink in his stomach, as he often jokes with Yang Hongyi, he is a real aviation "theorist", and in fact, he is indeed a "theorist".

The general idea can also be said clearly, but if it comes to the actual calculation and test, it is really a smear, in any case, he has never developed a combat aircraft, the reason why he wants to point out the flaws in Wei Hongkun's paper in public is nothing more than to let Wei Hongkun divert the pain of the wound being torn, after all, everything he sees and thinks about technology is technology.

Since the pain caused by technology, then use technology to make up for it, there must be nothing more than this to heal the scar in Wei Hongkun's heart, and in fact, it is true, Wei Hongkun is excited like a child, as for the wound that was accidentally torn by himself, it is estimated that it has long been thrown out of the clouds, but Lu Jiadong is also taking some risks by doing this, after all, he knows so much about the duck~~ wing layout with tailless triangle~~ wing.

If Wei Hongkun asked a few words in depth, even if he didn't show his stuff, he would inevitably be incoherent, and it was estimated that the wound would not be healed by then, but would worsen, but fortunately, Wei Hongkun didn't ask any more, at least that technically difficult self-talk was not used as a stepping stone to himself, which made Lu Jiadong very happy and very lucky

However, just when Lu Jiadong secretly rejoiced that his "plan" had succeeded, his heart suddenly chuckled and his throat was raised, because Wei Hongkun, who was not far away, suddenly shook his head, and muttered inadequately: "No, no", he immediately raised his head, looked at Lu Jiadong suspiciously, and asked involuntarily:

"Now that the main structure is determined, what about the engine, do we have a suitable aero engine?"

Hearing this, the aviation experts present couldn't help but be solemn again, but Lu Jiadong breathed a sigh of relief, as long as he didn't ask about advanced aviation technology, this kind of general direction had been laid out as early as a few years ago, so Lu Jiadong cleared his throat and said calmly and firmly:

"We don't have a high-thrust engine now, but we still have a medium-thrust engine, as early as two years ago, we introduced a full set of production lines and manufacturing processes from the United Kingdom, and now the Northwest Power Plant has a preliminary production capacity,"

"Then how will the radar be implemented?" 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, and the Central Plains Electronic Radar Institute has mastered all the core technologies, relying on this, it should not be difficult to develop a high-performance airborne radar that can be used to the air and has the ability to look down and fire downward!"

"What should I do with the control system of the aircraft? Duck ~~ Although the wing layout has many advantages, the disadvantages are also obvious, one of which is that the mechanical-hydraulic control system currently applied in China cannot be applied, but must be controlled by wire, and we are blank in this regard!"

"This can rest assured, we have already cooperated with France in this regard, their latest wire-based control and flight control software and flight control data, has been provided to us as an important project of technical exchanges, you must know that France is a technology pioneer in the field of duck ~~ wing layout and tailless triangle ~~ wing, their control system and software programming, has extremely important reference significance for us!"

Wei Hongkun's eyes widened, and he exclaimed incredulously: "Really!"

"Really!" Lu Jiadong nodded very affirmatively, then stretched out a finger, and said confidently and firmly: "All in all, we will use these mature technologies to build first-class fighters!" (To be continued.) )
