"By the way, I have a document for you." Lin Hongfei said with a smile, "About the American Lockheed. Martin recently newly designed a completely new fighter air intake. ”

"Lockheed. A fighter air intake recently designed by Martin? Director Jing's eyes widened, Lin Hongfei's words were really beyond his expectations, he was particularly aware of the impact of the design of the air intake on the performance of the fighter, and to put it bluntly, such an air intake that seems to have no characteristics and no technical content is one of the most technical places on the fighter fuselage! Although I don't know what the difference between this air intake is different from the one that everyone is using now, Director Jing's tone has become urgent, "Brand new? ”

"Brand new!" Lin Hongfei nodded affirmatively, thought about it, seemed to feel that it was not enough, and then added, "Revolutionary!" I don't think that in the next 20 years, even Russia and Europe as a whole will not be able to master this intake technique, except that we have the opportunity. ”

Director Jing's exhalation suddenly became extremely urgent, but after all, he was engaged in technical arts, and people who were born in technical techniques were usually more serious, even if his eyes were red, but his eyes were still wide-eyed, "Mr. Lin, you ...... There is evidence. ”

"Yes! The information is here, and after you read it, you will know that what I said is true or false. Lin Hongfei said, stretched out his hand to the back, and a young man standing behind Lin Hongfei respectfully handed the briefcase he was holding into Lin Hongfei's hand...... This young man is Lin Hongfei's new secretary, Uncle Wang's youngest son Wang Guoliang, as for Cao Jun, after the New Year, he has begun to take charge on his own.

Taking out a document from his bag, Lin Hongfei smiled and handed it to Director Jing. "Director Jing is an expert in aerodynamics and shape, and you will know whether it is feasible or not."

This is true, Director Jing also has this pride in his heart, whether this information is true or false, as long as you look at it, you can know that knowledge and science cannot be false...... Strictly speaking, from a scientific point of view, the Americans' "Star Wars" plan is also achievable. The only problem is that the level of science and technology in the current world has not reached the level of realizing the "Star Wars plan".

Almost snatched it, Director Jing snatched the information handed over by Lin Hongfei, but when he saw it at first glance, he was stunned: DiverterlessSupersonicInlet Inlet Inlet Technique. Supersonic air inlet without surface layer partition, also known as "three-dimensional bulge without surface layer partition air intake".

Below. is a hand-drawn diagram of a fighter's air intake and surrounding structures. This is a fighter with air intake design on both sides of the fuselage, but the structure of the air intake of the fighter is unusually simple, in the position of the air intake, it is neither the air intake cone design commonly used by the first and second generation jet fighters, nor the two-stage adjustable air intake ramp design commonly used now, it looks like a bulge. The position of the air intake of the fuselage was "swollen" with an irregular shape of a "pimple".

As if he had seen what Director Jing saw, Lin Hongfei added on the side, "The DSI air inlet uses a fixed bulge to simulate the first and second stage adjustable ramps in the conventional air intake, and can achieve compression of the airflow. If it is well designed, it can not only achieve the full performance of the conventional air intake, but also achieve the purpose of simplifying the structure, reducing weight and stealth. ”

Director Jing's hands were shaking: Baby! This is the real baby!

He is a high-tech man, and he is also an expert in aerodynamics and fluid mechanics in China, although the efficiency of this scheme is still to be discussed and calculated, but whether it is feasible he can see at a glance: feasible! It's so doable! If the air intake can really be designed in this way, it is equivalent to directly canceling the traditional air inlet channel one or two adjustable air intake control ramp plates and the entire control system, air release system, bypass system, etc., the future development trend of the fighter is the fuselage on both sides of the air intake or belly large import design...... This DSI intake alone can save almost 150 kilograms of aircraft weight!

150 kg, which is almost equivalent to being able to carry one more air-to-air missile!

"Isn't that possible?" Lin Hongfei breathed a sigh of relief.

"Feasible!" Director Jing nodded heavily, and then looked greedily down, and at the same time there was a hand-drawn air intake simulation diagram below, the difference is that this is a color drawing, which vividly shows the characteristics of the air flow before and after the air intake in different colors, which makes it clear at a glance.

Reluctantly closed this information, Director Jing smiled bitterly and shook his head, "I can't read it, I'll look at it after Mr. Lin leaves, or we won't be able to talk about it today." ”

He is "self-aware", and he knows that this information is a poison for any fighter designer.

"It's okay, Director Jing will watch it for a while if he likes it." Boss Lin breathed a sigh of relief and said hypocritically...... He was really afraid that this guy would not be able to stop if he fell into it.

Director Jing was really moved by Lin Hongfei's proposal, but after hesitating for a moment, he finally shook his head, "I'll look at it for a while, I'll watch it for a while," but he finally couldn't help it, hesitated for a moment, and said to Lin Hongfei, "This ...... Well, Mr. Kun, the most difficult part of DSI's inlet technique should be the design, processing and manufacturing of this 'bulge', right? ”

"Director Jing is really powerful!" Lin Hongfei gave a thumbs up, "That's right, in my opinion, the DSI inlet technique is much more difficult than the intake technique used on the current fighter jet, first of all, the design of this bulge requires a very high level of aerodynamics and computer technology, according to my understanding, this DSI intake is Lockheed. Martin has developed its own computer modeling tools based on computational fluid dynamics, which are not yet perfect; ”

"Secondly, its manufacturing precision requirements are very high, and it is very difficult for metal materials to be processed, and I personally believe that in 20 years, composite materials should be the first choice...... Of course, this is just my personal opinion, and how to do this thing well is still up to you people in the scene to explore. ”

Director Jing nodded again and again, and he also saw that the design of this three-dimensional surface is very difficult, and the amount of calculations that need to be done is very large, and it is necessary to ensure the air intake efficiency and engine working conditions of the aircraft at low speed, high subsonic speed, and supersonic speed, and also consider the materials and manufacturing process.

"By the way, there is another matter that may need the help of our comrades in the office." Lin Hongfei struck while the iron was hot and spoke.

"Mr. Lin, even if you say that as long as we can help 611, we will definitely not be ambiguous." Just got such a treasure from Lin Hongfei, Director Jing was in a good mood, "The superior leader said, let us fully cooperate with you without affecting the work, but first of all, we really don't have many good people here except for people." ”

"I'm interested in you people here," Lin Hongfei said with a smile, and after speaking, he hesitated for a moment, because even now, he was not very sure whether it was a good thing or a bad thing to do this, but in the end he gritted his teeth and said, "Possibly...... More than three months ago, Ukraine and the U.S. government reached an agreement on the "Treaty on U.S. Assistance to Ukraine in the Destruction of Strategic Nuclear Weapons and the Prevention of the Proliferation of Weapons of Mass Destruction". ”

"Zhilu said," Director Jing nodded again and again, and when he talked about this matter, Director Jing's face was full of regret, "This is the foundation of a country's stability and development, without these weapons and equipment, what does Ukraine rely on to defend its country?" How can their politicians be so short-sighted......"

"Ukraine's current domestic economic situation is simply not able to feed such a huge strategic nuclear weapons and strategic offensive equipment, after the collapse of the Soviet Union, in the foreseeable future, Ukraine will not be able to become a world power, even regional power is difficult, these things are not much use for Ukraine, for the current Ukraine, the most important thing is to fill the stomach, it seems to be quite cost-effective to be able to exchange these things that they cannot use in the future for money......" Lin Hongfei said, But there was clearly a bit of ridicule in his eyes.

"That being said, but ......" Director Jing shook his head with a sad face, he is a person from the military industrial system, and he is naturally particularly concerned about these strategic military equipment related to the development of a country's strategic space, and the importance of these things to a country is naturally very clear, but Lin Hongfei's words also make sense, the current situation in Ukraine, it is really better to keep these things than to dismantle them and sell them for money.

"Our company is in contact with the Ukrainian side to establish a National Air and Space Museum of Ukraine in Ukraine, modeled after the National Air and Space Museum of the United States, well...... This collection not only has all the exhibits since Ukraine's aviation industry, but also exhibits of Ukraine's achievements in the aerospace industry, and we also seek to establish a flight demonstration team......" Lin Hongfei said, "We hope that our 611 Institute can send some comrades to help us train a group of ground staff and technicians to assist us in the maintenance of aircraft. ”

Lin Hongfei said very vaguely, but who is Director Jing? It is definitely not possible to let him engage in politics, but the sensitivity of his technique is beyond the reach of Lin Hongfei, his eyes instantly widened, his whole body leaned forward hard, and almost everyone was stuck on the table, "Mr. Lin, what do you mean...... These planes, are they all well preserved? ”

Because he was too excited, Director Jing's fists were clenched very closely, and his voice trembled slightly: If these planes are all well-preserved and able to fly, even if they only preserve the basic flight ability, it will be of great significance to the 611 Institute and even the entire republic!
