Chapter 118 - "v" Forward Sweep! (1/2)
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
