In the process of developing a new fourth-generation fighter, the Air Force must first put forward requirements and predetermined targets, then select a plan, conduct preliminary research, and set up a project, and finally put it into mass production; I don't know what kind of difficulties it will encounter during the actual development period, and the length of the development cycle must at least span 15 to 20 years.

Z-1 prototype, after a long period of study and understanding, Zuo Xue through the absorption of various means and design ideas to improve stealth performance, combined with the design concept of J-20 and J-31, found a new way, directly pointed to the most important stealth performance, by the binary rectangular vector and the concept of reducing the radar reflection lobe, to strengthen it.

It's just that after the canard wing is canceled, this concept aircraft that exists in my mind has strong stealth performance, but its maneuverability is not as good as the J-20, which can be called against the sky.

No way, the aerodynamic efficiency given by the canard wing is too high to be compared at all.

However, she went to Chengfei, the world's most recognized player of the strongest canard aerodynamic layout, daring to be the first in the world, using canard wings in the field of fourth-generation aircraft, and trying to reduce the problem of canard aerodynamic layout for stealth walking.

From a practical point of view, this first work carefully studied on campus is estimated to be an alternative due to the cancellation of Cheng Fei's signature aerodynamic layout of canard wings, which is his best name, and there is a 99.9% chance that it will not be adopted.

Focusing on stealth, the Z-1 fourth-generation aircraft, which actually belongs to the mass market, wants to actually develop and mass produce and put into service, which is just an ethereal dream.

After the J-20 was born, it is understandable to squeeze out the status of the J-10 "Raptor" and become the most important core product sequence of Chengfei.

Of course, if it is really developed, God knows if the outside world will celebrate, Shen Huoyi successfully captured Chengluoma?

"It's already good, take your time, don't rush, I'll go back and see what your concept map looks like."

Zhou Hai looked at Zuo Xue's slightly lonely appearance and comforted: "At least this design idea and concept is stronger than the little devil's mind." ”

From a psychological point of view, if there is someone who is worse than you, the feeling of loss and pessimism will be reduced a lot.

"Strategically to despise the enemy, tactically to pay attention to the enemy, don't underestimate the mind, this is the use of YF-23 aerodynamic shape design of the fourth-generation fighter, although there are many shortcomings, but from the perspective of flight design alone, the mind due to the size of the compact size, edge strips and structure optimization, stealth ability to reach an excellent level, I analyze the heart of the reflection lobe only 10, second only to F-22."

Designing the excess of the other side of the ocean, Zuo Xue's face is solemn, his mentality is correct, and he has no contempt, pointing out the advantages and disadvantages one by one from the perspective of aircraft designers, and commented: "The little devil has the ambition to revitalize the aviation industry, and has expectations for the mind, but he lacks manufacturing experience and technology, and there is no shadow for decades before and after, and he is blind to a good aerodynamic layout." ”

Japan's ATD-X 'Shinshin' fighter is based on the YF-23 'Black Widow' fighter that was defeated that year, and its aerodynamic design is extremely excellent.

In that year, the YF-23 'Black Widow' and YF-22 'Raptor' competed for the development model of the U.S. military's advanced tactical fighter contract, and the reason for their defeat was not backward in technology and performance, but overall superiority over the Raptor.

At the beginning of the 21 st century, when the country on the other side of the ocean announced that it had set up a project to develop the ATD-X 'Xinshen' fighter, it could be described as a sensation all over the world and caused unprecedented pressure and shock to various Asian regions.

In 2000, our air force was still using a large number of second-generation aircraft such as J-6, J-7 and J-8, a small number of imported Su-27, J-10 was officially put into service and there was no shadow, and the F-15J fleet was already extremely chicken-eating.

however

A year has passed,

Ten years have passed,

Twenty years have passed.

At that time, the nervous aviation people who were scared went from having the courage to face it to moving forward bravely, from being frightened to looking puzzled, with a trace of confusion.

What about the goods?

What about things?

What about the mind?

The rumored mental aircraft group that has been overwhelming has not appeared in the Asian sky to show off its might, and it is still the F-15J and a small number of F-2 aircraft groups imitating the F-16 "Falcon" carrying the girder.

The mind based on the 'Black Widow' has been tossed back and forth so far, spanning 20 years, under the slogan of 'experimental aircraft', the eight-ton empty-weight experimental aircraft has only made a few first flights.

The experimental machine is not like the experimental machine, and the comprehensive performance of the mass production machine is too scum, unable to meet the standard, coupled with various technical problems and the pressure of the United States, it made everyone panic back then, and was in an embarrassing state.

After the J-20 was born and the FC-31 gradually matured, the status of the self-developed mind declined again, and the Japanese team had no choice but to purchase F-35 to confront.

Although the mind is not good, it is undeniable that the aerodynamic layout meets the stealth standard and is still excellent.

It is necessary to see not only the shortcomings, but also the shining points.

As an aircraft designer, when the engine is not powerful, you can only rack your brains, use your imagination and creativity, and design the most suitable aerodynamic layout for yourself to make up for the lack of engine thrust.

Seeing the high-spirited Zuo Xue, Zhou Hai smiled slightly, hugged the girl and walked back, looking forward to the works she created.

The sky was dark, the night fell, facing the river breeze, all the way out of the rooftop, stopped a taxi, and the two quickly returned to the Red Maple Hotel.

I didn't go shopping to buy clothes and shoes, mainly because the stamina of red wine slowly rose, Zuo Xue, the girl, was quite conscious, and her body was a little weak.

It's impossible to go shopping anymore, or go back to the hotel room.

……

Go upstairs, go back to your room, and lock the door.

Zuo Xue sat on the edge of the bed, exhaled a breath of heat, tried to straighten her back, opened the locked luggage backpack, took out a carefully kept picture album from it, handed it to Zhou Hai, and a smile appeared on her pretty face: "There is the Z-1 I created in it, and there are several designs that are biased towards the sci-fi avant-garde type, I like Z-3 the most, this is a small gift for you, keep it safe." ”

Other girls give gifts are small objects, but this girl is good, and she is directly a delicate fighter concept picture book, all original and carefully crafted.

Zhou Hai nodded, took the album, turned the first page, and the avant-garde and detailed Z-1 fourth-generation stealth concept map immediately came into view.

The concept map can barely be regarded as the initial blueprint, with three views on the front side in different directions, thin blue lines accurately outlining the entire fighter, no canard wings, central trapezoidal main wing, vertical tail camber 28.5 degrees, upper and lower areas of the fuselage, smooth lines and sharp corners, strictly maintain the design requirements of stealth theory, and minimize radar scattering.

The wing strips are processed to predict that the coefficient of favorable interference vortices can be increased, and the DSI inlet design on both sides is adopted to further reduce radar scattering, and the aileron and horizontal tail are trapezoidal planes.
