Chapter 118 - "v" Forward Sweep!

However, several large wind tunnels and supercomputers in china can easily be used to design and deduce the best aircraft, but the fighter jet produced in batches can not only be produced in the laboratory

The cost of a prototype is often several billion or even hundreds of millions of dollars, and it takes a long time

There are more than ten design institutes and several related manufacturing enterprises in the country

They can only launch a mature aircraft every few years

It is precisely because of the existing production conditions that they have to select the most compatible and most effective aircraft

Uncle yan's sketchbook had a deep background in hand-drawing, and he recorded the perfect shape of the plane that he had conceived on a shelf, vividly, as if it would jump out of the paper at any time

It was completely different from the model that could be seen at present, and the airframe design that only existed in the concept had a more futuristic feel, and some of them had been verified by wind tunnels and large computers and marked out some simple conventional data

These are the perfect aerodynamic arrangements

Although the idea was novel and advanced, it was of little value to other national intelligence organizations

In any aircraft design company, there were many of these types of drawings, and they were often limited to the drawings because of the production process and cost constraints

There is no value in making experimental machines, and how much threat can there be if there is no solid design, not to mention with the passage of time and scientific and technological progress, more advanced structural design will also emerge continuously with the imaginative brain of human beings

"The forward swept wing fighter is so beautiful, no wonder it can't be produced, and the requirements for the airframe have increased

The deformed wing is really bold

No other manufacturer can produce the current processing technology

The old f is already reaching its limit

" Lin mo flipped through it, and there were a lot of models in it that made him look quite mi

The forward-swept aircraft is an aircraft whose front and rear edges extend forward (forward-swept)

Its tip chord is in front of the root chord, and its left and right wing are projected into a v shape

The principle of delaying jibo generation of forward-swept and backward wings is exactly the same

Compared with the conventional backward swept wing, the forward swept wing can directly increase the load by 30 %, increase the angle change speed by 14 %, increase the combat radius by 34 %, and shorten the take-off and landing distance by 35 %, completely improving the controllable xing of the aircraft at low speed

It can improve the aerodynamics efficiency, reduce the stall speed, and ensure that the plane is not easy to enter the spiral in all flight conditions

Thus, the safe and reliable xing of the aircraft is greatly improved

Moreover, when combined with the thrust vector control system, its short-range air combat maneuverability will be doubled

This was a completely generational technological upgrade, and there were no large number of forward-swept aircraft in each country

This was not because every country's air force had no knowledge of forward-swept wings, but because the advantages of forward-swept wings were very obvious, and the defects were very obvious, because of the structure, Bending along the structural curve will increase the outer wing along the airflow direction

This phenomenon is called bending and twisting dispersion

At a high enough speed, this phenomenon will form a vicious circle until the wing bends and breaks

Because of this, there are only a few types of forward-swept aircraft, such as the german jun-289 bomber designed in 1944, the american x-29 and the russian su-47 golden eagle

However, the deformable wing is a more advanced type of aircraft proposed after 2000

The adaptability, maneuverability and survivability of the deformable wing have been improved more obviously

In many people's eyes, it is already a science fiction concept

It could even hover, fly backward, and glide sideways like a bird

At the same time, it also put forward higher requirements for new intelligent materials, ji exciters, sensors and locks, and it must be seamless deformation in the process of deformation

Otherwise, it would be torn apart by the air in flight

It had to be said that uncle yan's expert brand was steel and steel, and the design of the machine was mei lun mei huan, but the ideal was beautiful, the reality was cruel, these very perfect models, but because of the technical and material conditions, they could not be produced, and even if they were produced, It was also affected by the physical condition of the pilots

Think about it, even if the last Evil with a population of one billion could produce a super fighter just for them, which was physically and responsibly defying the heavens, would that be possible

A fighter plane could shoot down at most a few enemy planes even if it was a trump card, but in the end, it would fight more people and less people

At the end of the second world war, the technical advantage of the me262 jet fighter could not save the last hope of nazi germany

Because of this, Lin Mo could see Uncle yan's book, but it was a priceless treasure to him

Materials

Would there be a strong problem with Golden dragon that had devoured a variety of rare metals

The answer is: no 1 is a good hand at transforming the body, and this is not a problem

So, for Lin Mo, the aerodynamic layout of these models was only hu in the water, moon, and mirror

On the contrary, as long as the Golden dragon is willing, it can evolve and even be more perfect

The model in the picture book even indicated more sizes and specifications

For Lin Mo, it was full of deadly youhu power

He looked at him with bright eyes and wished he could run straight into his arms

"I say, professor Yan Da," Lin Mo suddenly said to Uncle yan, who was still eating, with a smile on his face

He changed the title one by one

"Well, obituary boy, tell me what happened

How did you know I was a professor

" Uncle yan could see that Lin Mo liked this book, and he was very happy in his heart

Hero knows hero

What a designer of a good plane needs most is the approval of the pilot

Or a professor

Lin Mo was overjoyed that a blind cat had run into a dead mouse

The book contained even more gold

"Let's discuss something

Can you give me this album

Sell it to me

Tell me the price

" Lin Mo even wanted to get the book quickly and trick Golden dragon Jin Bi into evolving it to give him a taste

"No, no, no

The actors don't sell for any money

" Uncle yan shook his head like a rattle drum and rolled his eyes

It was his life's work

Others liked it, but it was also his own treasure

Don't try to change the amount of money

Although he didn't have the chance to become a real person, he was just like his own child, condensing the efforts of himself and other experts

It was also the crystallization of wisdom and sweat

"It's not a military secret

Besides, it's not a beautiful color page, but I like it very much

Uncle, it's not as beautiful as being an adult

" When it came to tricking, Lin Mo's brazen face seemed natural

If it were an ordinary person, it wouldn't be a treasure

No one wanted it for free, but it meant a lot to Lin Mo

"No discussion

I only have this one

I'll leave it for myself when I retire

What do I do if you take it

" These books had a deeper meaning for Uncle yan

As he grew older, he loved them for the rest of his life

Although he couldn't work as hard at work as he used to, the knowledge he had accumulated in his life had never thought of giving up

Uncle yan even regretted letting this young man see his baby

"How about the photocopying

It should be fine

" Lin Mo was fixated on Uncle yan's precious heart, and didn't intend to float past him so easily

"Copy

That's not impossible

" Uncle yan hesitated for a moment and nodded

After all, it was not a valuable treasure

It was just something to entertain himself and play retirement time

"Ha, great

" Lin Mo almost jumped up, hugged the book and asked, "Uncle yan, is there anything else

" He was obviously in possession of long and looked back at shu

He guessed that Uncle yan had worked for so many years and had more than that

"Yes, if you really want it, you can come to my house when the exhibition is over

I'll show it to you

Remember, you can only copy it, you can't take it away

" Uncle yan sighed with relief

Since he didn't steal his treasure, it wouldn't hurt to share it

Suddenly, he heard the sound of a loudspeaker in the distance

Then, a huge roar began to sound

It was time for the flight performance

Uncle yan quickly finished the lunch box, took a piece of paper, wrote down his contact information, and handed it to Lin Mo

"Here you go

This is my name and my home phone

Use this to contact me

The flight show is about to start

Don't forget to take pictures for me

" Lin Mo took the paper

Yan Guoqiang, phone number: 0755 xxxxxx, it seems that Uncle yan still came from Shenzhen

"No problem

" He immediately adjusted the dv and started aiming it at the sky

"Look at the devil's side skin

" Someone nearby shouted

Soon, six j-10 squadrons flew through the sky in dense formation

"Quick, quick, quick

" Uncle yan couldn't wait to hold a telescope and aim it at the six j-10s, "Look at the air intake

It's the j-108s

This formation is dense enough

It's about ten meters away

" Lin Mo took the dv and aimed it at the formation

He kept adjusting the focus and taking pictures of every detail of the plane

According to his professional vision, what he took was definitely in line with Uncle yan's requirements

After that, the sky was filled with graffiti

The colorful smoke was set against the blue sky, depicting exquisite patterns

These were not standard tactical actions

But it tested the pilot's driving skills and the ability of the body

Followed by su-27 "Saber," f-16 "War falcon," jas-39 "Eagle lion

" They were all flying in shifts, performing a highly skilled fighter formation, but Lin Mo's eyes widened, and he used the dv to tightly lock the movements of these planes in the air, not even a single shake was spared

Uncle yan's nagging about the merits and demerits of each type of aircraft was like a voice-over note

It gave lin mo a deeper understanding

: It's only a few days after the end of the month

Give me all the remaining monthly votes
