A few days later, Liu Haotian, deputy chief of the general staff, finished his inspection of the Wanshan military industrial production complex and returned to Beijing alone, followed by Lu Jiadong and Jiang Huichuan jointly drafted the "small steps and fast running" weapons and equipment development plan, for this development plan of great practical significance and value, the leaders of the military ~ ~ committee and high-level leaders attached great importance to it;

At the meeting, Liu Haotian, deputy chief of the general staff, made a briefing on the situation, Navy Commander Jiang Huichuan gave a briefing on the results of the Navy's experiments, and Lu Jiadong, who was ordered to give an explanation, gave a detailed account on the development of weapons and equipment in "small steps and fast running."

It is not difficult to understand the development of weapons and equipment in "small steps", and the long-term development plan and gradual catch-up with the world's advanced level are also in line with the actual national conditions of China at present, and because of this, this development plan was quickly approved by the leaders and high-level leaders of the military ~ ~ committee;

And at the enlarged meeting of the Military ~~ Committee at the end of 85 years, it was officially determined as a feasible way of development, and at the same time, based on this mode of development, several pilot projects such as the Navy's new missile destroyer, new main battle tank, and universal tracked chassis were determined!

Not only that, but it has also been listed as a key national project in the "Seventh Five-Year Plan" (the Seventh Five-Year Plan 1986-1990) and has been supported by special state funds

With this strong spring breeze, the development process of the new multi-role fighter, which is already in full swing, is like sprinkling a layer of oil on the fire, and its development momentum is even more unstoppable, the "Yinhe No. 1" mainframe computer located in the national defense ~~science and technology~~ university, the wind tunnel group located in the southwest mountainous area, and the fluid experiment center in Beijing have all opened the door to the new multi-role fighter;

Yang Hongyi, Cheng Yuanhang, Wei Hongkun and other experts from Wanshan Aviation Research Institute, relying on so many advanced research and development equipment and basic experimental facilities, can be said to be like a tiger with wings, you must know that these old experts have extremely rich experience and incomparably profound knowledge;

A lot of aerodynamic shapes, advanced structural ideas, has long been sketched in their minds, but due to the limitation of equipment, can not carry out relevant theoretical demonstration, now in Wanshan factory with abundant financial support, in the country's key support, a large number of advanced basic equipment for its use, suddenly glow with strong creativity!

By the beginning of 86, the first draft of the new multi-role fighter with three basic types was increased to nine, and the optically coupled duck ~~ wing shape was made more than 20, not only that, Yang Hongyi and Wei Hongkun redesigned the nose and air intake in order to make the new aircraft have a more perfect aerodynamic shape, so that the wide air intakes on both sides of the old Jianjiu became inverted, and the wings and fuselage were organically integrated, thereby reducing flight resistance and improving flight performance;

In the selection of imports, Yang Hongyi and Wei Hongkun have also made great efforts, from the current popular wedge-shaped air intake, to a rectangular air inlet similar to J-8II; from the French semi-buried air intake, to the unique smile type air intake, the two old experts have tested no less than 100 kinds of before and after, just when people are looking forward to what kind of innovative solutions the two old experts will come up with, a big surprise happened, Yang Hongyi and Wei Hongkun's air intake plan is indeed very unique, unique and simply speechless.

Because their intake scheme is not the shape of the inlet in the usual sense, but a slightly arc-shaped semi-circular shape, if only this is good, the most important thing is that two large bulges like cheek raisers are installed at the inlet, and the auxiliary air intake and air vent are canceled at the same time, such a subversive design, it is difficult to imagine whether this is the foresight of two old experts, or the willful move of a pair of old naughty boys!

When the model of the aircraft with the new air inlet scheme was presented in front of Lu Jiadong, it really made him, a military expert who had traveled from later generations, startled, and looked directly at the two experts on the sofa opposite, and looked directly at the aircraft model on the desk in disbelief:

"This is what you did?"

Lu Jiadong rarely has such a shocked appearance, especially in the field of military industry, to say that the shock is given by him to others, and because of this, in the Wanshan military production complex, Lu Jiadong always gives people a sense of indifference and stability, at least in the eyes of Wei Hongkun, who has not been joining for a long time, so when he saw Lu Jiadong's shocked expression, he did not feel that it was his almost perfect design that surprised Lu Jiadong, but felt that something was wrong.

After all, this kind of "bulging" air inlet structure is a new thing without precedent, and it has caused a lot of controversy within the aviation institute, and now seeing that Lu Jiadong is so similar to those opponents at first sight, Wei Hongkun's heart is in his throat for no reason, and his hands are also tightly clutching his cotton clothes!

Yang Hongyi and Lu Jiadong have worked together for many years, not to mention close relatives and friends, they are also one of the best New Year's friends, so Yang Hongyi is not as nervous as Wei Hongkun, but seeing Lu Jiadong's expression, he couldn't help frowning, took a sip of the tea in front of him and moistened his throat, and then explained:

"Xiao Lu, this air intake is unique to me and Lao Wei based on decades of experience, maybe because it is too new, it may be a little lacking, and it may be unacceptable, but I can responsibly say that this air intake is indeed more beneficial than disadvantageous, I and Lao Wei have used the wind tunnel and the 'galaxy' computer to verify:

First of all, we use the "cone flow" wave-riding design, the total pressure recovery is higher; this streamlined bulge reduces the resistance of the windward side of the aircraft, covering the turbine blades of the aircraft engine, so as to reduce the detection effect of the radar; and finally and most importantly, the application of such a simple bulge not only does not design the auxiliary intake valve and air release valve, but also can cancel the attached surface layer partition, so that the aircraft can reduce the weight of hundreds of kilograms, greatly reducing the structural weight of the aircraft. Overall, this bulge inlet has the characteristics of simple structure, light weight, low resistance, and invisibility."

Yang Hongyi talked eloquently, telling the characteristics and performance of the new air intake designed by him and Wei Hongkun one by one, but Lu Jiadong didn't seem to hear what Yang Hongyi was saying at all, and kept staring at Yang Hongyi, who was a little dry-mouthed, which made Yang Hongyi also wonder, and said What happened to Xiao Lu today? So the words froze, and he also stared at Lu Jiadong for a while, and then slowly asked:

"Xiao Lu, are you okay today? Why are you just staring at us two old men? Did you understand what I just said?"

"I understand, I don't understand!"

"What I said, to understand is to understand, not to understand is not to understand, you wait, I'll take out the paper, write you a few equations, draw a few drawings and you will understand"

Yang Hongyi didn't say a word, he directly picked up his briefcase, took out paper and pen, wrote two mathematical formulas on it, and handed them to Lu Jiadong.

"Lao Yang, what is your WeChat ID?"

"What is WeChat?"

This time it was Yang Hongyi's turn to be puzzled, but Lu Jiadong didn't care about this, turned his eyes to Wei Hongkun's side, and continued to ask, "Old Wei, what about yours?"

"Mine?" Wei Hongkun replied in surprise, but then frowned and asked, "What is WeChat?

Lu Jiadong waved his hand again and again: "No, no!"

The two old experts sometimes have one thing to say, and there are two people who say two, and the lie can't be hidden on their faces at all, and because of this, when Lu Jiadong looked at Yang Hongyi and Wei Hongkun's surprised and puzzled expressions, the pounding heart in his chest finally calmed down a little, no way, the new air inlet scheme proposed by the two old experts was too shocking, so shocking that Lu Jiadong felt that the two people in front of him were not people of this era at all;

You must know that the "bulging" air intake in Yang Hongyi's mouth was officially called DSI air intake in later generations, also known as the "mussel" air intake, which was originally developed by the American Lockheed Martin Company in the 90s and successfully applied to the fourth-generation fighter F-35.

China has gradually mastered this advanced air intake technology from the beginning of the new century, and applied it to the "Snapdragon", the improved J-10, the fourth-generation fighter J-20, and the J-31, but I didn't expect that this air inlet mode that should appear in later generations was actually studied by Yang Hongyi and Wei Hongkun, which could not help but shock Lu Jiadong, and even wondered if these two old experts were also traversers like themselves.

Because of this, Lu Jiadong will ask if there is a WeChat account that only future generations can understand, and the results obtained made Lu Jiadong even more shocked, the two are not crossers, as for the DSI air intake is created through hundreds of experiments and the experience of the two experts for many years, after learning the truth, Lu Jiadong had to admire the profound knowledge of these two old experts

"I think this kind of air intake is very good, if it is perfected, it can be applied to our new multi-role fighter, by the way, is there a name for this new air intake?"

Lu Jiadong, who returned to normal, quickly determined the new air intake to be the aerodynamic mode of the multi-role fighter, which made Wei Hongkun, who had been worried, finally settle down, and shook his head with a smile:

"We all call it a bulge! Lao Yang thinks he wants a mussel, so he also calls it a 'mussel' air intake!"

"It's not good, it's not good!" Lu Jiadong waved his hand again and again: "Let me see, since it is the air intake developed by the two of you, it is simply called 'Yang Wei' air intake, and this name will be used!" (To be continued.) )
