However, several large-scale wind tunnels and leapfrog computers in China can easily handle the design and deduction of the best aircraft models. However, mass-produced fighter jets cannot only be produced in a laboratory. The cost of a prototype aircraft is often as high as
Billions or even hundreds of millions of dollars, and it takes a long time. More than a dozen design institutes and several related manufacturing companies across the country can only launch a mature model every few years. It is precisely because they need to adapt to the existing production conditions.
The model that best matches it and is also the most combat effective is selected.
In the album, Uncle Yan's profound hand-drawing skills allowed him to vividly record the perfect aircraft shapes he conceived on paper, as if they would jump out of the paper at any time.
It is completely different from the models that can be seen currently. The body design that only exists in concepts is more futuristic, and some of them have been verified by wind tunnels and large computers, and some simple conventional data are marked. Even so,
It is also shocking enough to see. These are truly perfect aerodynamic layouts.
Although the concept is novel and advanced, it is of little value to the intelligence organizations of other countries. In any aircraft design company, there are many drawings of this type, and they are often limited to existing drawings because of the production process.
and cost constraints, there is no value in making an experimental machine. How much threat can there be without a physical design? What's more, with the passage of time and the advancement of science and technology, more advanced structural designs will also be developed with the rich imagination of human beings.
The brain is constantly emerging.
"The forward-swept wing fighter is so beautiful. No wonder it cannot be produced. The requirements for the aircraft body have increased. The deformable wing is really bold. No manufacturer can produce it with the existing processing technology. The F old one has already reached its limit.
." Lin Mo flipped through it, and he was fascinated by the many models of models in it.
A forward-swept wing aircraft is an aircraft with the front and rear edges of the wings stretched forward (swept forward). Its tip chord is in front of the root chord. The left and right wings form a V shape when viewed from above. The forward-swept wing and the rear-swept wing are delayed by jibo.
The principles of production are exactly the same.
Compared with conventional swept-wing aircraft, forward-swept wings can directly increase the load capacity by 30%, increase the transition angle speed by 14%, increase the combat radius by 34%, and shorten the take-off and landing distance by 35%, which completely improves the aircraft's ability to fly at low speeds.
It is controllable and can improve aerodynamic efficiency in all flight conditions, reduce stall speed, and ensure that the aircraft is not easy to enter a spiral, thus greatly improving the safety and reliability of the aircraft. It can also be used in combination with the thrust vector control system to achieve close air combat maneuverability.
Ability will be increased exponentially.
This is completely a cross-generation technological improvement. There are not a large number of forward-swept wing models in various countries. This is not because the air force of each country has no knowledge of forward-swept wings, but because the advantages of forward-swept wings are obvious and the shortcomings are
It is also very obvious that due to structural reasons, the bending deformation along the direction of the structural curve will cause the outer wing to increase in the direction of the airflow. This phenomenon is called bending and twisting. At a high enough speed, this phenomenon will form a vicious cycle until
causing the wings to bend and break.
Because of this, there are currently only a few forward-swept wing models such as the Junkers JU-289 bomber designed by Germany in 1944, the American X-29, and the Russian Su-47 Golden Eagle.
The morphing wing is a more advanced aircraft model proposed after 2000. The adaptability, maneuverability and actual combat survivability of the morphing wing have been significantly improved. In the eyes of many people, it is already a science fiction concept, and can even
Hovering, flying upside down and gliding sideways like a bird also puts forward higher requirements for new smart materials, actuators, sensors and locks and other mechanisms, and the deformation process must be seamless, otherwise it will
It will be torn apart by the air during flight.
It must be said that Uncle Yan’s signature brand of expertise is the hardness of steel and the beautiful designs of machines. However, the ideal is beautiful, but the reality is cruel. These perfect models cannot be produced due to technical and material conditions.
, and even if it is produced, it will be affected by the physical condition of the pilot. Just imagine, even if you select a monster with incredible physical fitness and reaction ability out of a billion people, and just produce a super fighter for them, is it possible?
?A fighter jet can only shoot down a few enemy planes at most, even if it is an ace. In the end, the battle is to have more people and fewer people.
At the end of World War II, the technical advantages of the Me262 jet fighter could not save Nazi Germany's last hope.
It was also because of this that Lin Mo was able to see Uncle Yan's album, but for him, it was a priceless treasure.
Material? Will a gold-type dragon that has swallowed many rare metals have strong problems? [Answer] The answer is: no1
Bianjujin Dragon Tianzhi is a master of body transformation, so this is not a problem.
So to Lin Mo, the aerodynamic layout of these models is just like a moon in the water or a huā in the mirror? On the contrary, as long as the golden dragon is willing, he can evolve the above models at any time, and even make them more perfect.
The models in the brochure even indicated more sizes and specifications. For Lin Mo, they were full of fatal energy, which made his eyes light up and he wanted to just hug him and run away.
"I say, Professor Yan Dadian, Yan Zhuanyan," Lin Mo suddenly put on a smile and said to Uncle Yan who was still eating next to him, changing his titles twice in a row.
"Well, boy, what are you talking about? How did you know that I am a professor?
"Uncle Yan could see that Lin Mo liked this album, and he was very happy in his heart. Heroes recognize heroes. Isn't what a plane designer needs most the pilot's approval?
Or Professor?! It was really a blind cat that encountered a dead mouse. Lin Mo was overjoyed. The value of the pictures in this book was even higher.
"Let's discuss something. Can you give this album to me? You can also sell it to me. Let's decide how much it will cost." Lin Mo even wanted to get this album quickly and then deceive the gold dragon.
The gold coins evolved and let him experience it.
"No, no, no, I won't sell it for any price." Uncle Yan shook his head like a rattle and rolled his eyes. This is his hard work for most of his life. If others like it, they will like it. This is also his treasure. No matter how much money he has, he can't change it.
Go, although there is no chance to become a physical entity, it is just like my own child. It is a condensed effort of myself and other experts, and it is also the crystallization of wisdom and sweat.
"This is not a military secret, nor is it an exquisite coloring page, but I like it very much, uncle, it's not as beautiful as an adult!" When it comes to playing tricks, Lin Mo's shamelessness seems to be natural. If it were an ordinary person, this would not be the case.
It’s not a treasure. It’s given away for free and no one wants it, but it means a lot to Lin Mo. “There’s no need to discuss it. I’ll just take this one and keep it as a souvenir for myself after I retire. If you take it, what should I do?”
Do?" These picture albums have a deeper meaning to Uncle Yan. As he gets older, he will only like this thing in his life. Although he can no longer be busy in the workplace as before, he has accumulated a lot of money in his life.
I never thought about giving up the knowledge I gained.
Uncle Yan even regretted letting this young man see his baby.
"What about copying? It should be no problem." Lin Mo kept his eye on Uncle Yan's beloved child and had no intention of passing it by so easily.
"Copying? That's not impossible." Uncle Yan hesitated for a moment, then nodded. After all, it wasn't a valuable treasure, it was just something for his own entertainment and retirement time.
"Ha, that's great." Lin Mo almost jumped up. He hugged the booklet and asked, "Uncle Yan, are there any more of this?" He obviously had acquired Long and looked back at Shu, guessing that Uncle Yan was working
After so many years, there should be more than this amount of inventory.
"Yes, if you sincerely want it, when the exhibition is over, you can come to my house and I will show it to you! Remember, you can only make copies and cannot take them away." Uncle Yan breathed a sigh of relief. Since he was not trying to steal his treasure,
So it doesn’t hurt to share it.
Suddenly, I heard the sound of a loudspeaker in the distance, and then a huge roar began to sound. It turned out that the flight show time had arrived.
Uncle Yan hurriedly finished the lunch, took a piece of paper, wrote down his contact information, and handed it to Lin Mo. "Look at it, this is my name and home phone number. Use this to contact me whenever you want to fly."
It’s about to start, don’t forget to help me take pictures.”
Lin Mo took the piece of paper, Yan Guoqiang, phone number: 0755xxxxxxx, it seems that Uncle Yan came over from Shenzhen. "No problem."
As he spoke, he immediately adjusted the DV player and started pointing it at the sky.
"Look at the devil's side," someone shouted nearby. Soon, six J-10s flew through the sky in a dense formation.
"Shoot, snap, snap!" Uncle Yan couldn't wait to hold a telescope and pointed it at the six J-10s, and said: "Look at the air inlet, it's the J-108. This formation is dense enough.
It’s probably only a dozen meters away.”
Lin Mo took a dv and pointed it at the formation and took a lot of shots, constantly adjusting the focus to take pictures of every detail of the aircraft. With his professional vision, what he took must meet Uncle Yan's requirements.
Then aerobatic maneuvers such as the Goddess Scattering Flowers and the Laying of Arhats were performed one by one. It was like graffiti was painted in the sky. With the blue sky as the background, the colorful smoke painted exquisite patterns. These are not standard tactical moves, but they are more special.
Test the pilot's driving skills and aircraft performance.
Immediately afterwards, the Su-27 "Sabre", the F-16 "Fighting Falcon", and the JAS-39 "Griffin" all took turns to fly into the sky, performing a highly skilled fighter formation. However, Lin Mo's eyes widened and he locked onto the DV
He noticed the movements of these aircraft in the air, not even a trace of shaking. In his ears, Uncle Yan's chatter about the pros and cons of each model of aircraft was like a voice-over comment, which gave Lin Mo a deeper understanding.
