In the development process of a new fourth-generation fighter aircraft, the Air Force must first put forward requirements and predetermined indicators, then select a plan, pre-research, and project approval, and finally reach mass production and service. It is unknown what difficulties will be encountered during the actual development period, and the length of the development cycle It should span at least fifteen to twenty years.
After long-term study and understanding of the Z-1 prototype, Zuo Xue absorbed various means and design ideas to improve stealth performance, combined with the design concepts of the J-20 and J-31, and found a new way to focus on the most important thing. Stealth performance is enhanced by the concept of binary rectangular vectors and reduced radar reflection lobes.
However, after canceling the canards, this concept aircraft that exists in the mind has strong stealth performance, but its maneuverability is not as good as the J-20, which is said to be incredible.
There is no way, the aerodynamic efficiency given by the canard is too high, it is completely incomparable.
However, she went to Chengfei, the world recognized as the strongest canard aerodynamic layout player, dared to be the first in the world, used canards in the field of fourth-generation aircraft, and tried to reduce the problems of canard aerodynamic layout on stealth walking.
From a practical point of view, this first work, which was carefully studied on campus, is expected to become an alternative due to the cancellation of the iconic aerodynamic layout of the canard that Chengdu Aircraft is best at, and there is a 99.9% chance that it will not be adopted.
The Z-1 fourth-generation aircraft, which focuses on stealth and is actually a mass product, is just a vague dream if it is actually developed and put into mass production.
After the birth of the J-20, it is understandable that it has dethroned the status of the J-10 Raptor and entered the most important core product series of Chengdu Aircraft. The country can no longer spend tens of billions of dollars to develop this mediocre product. A concept main fighter focused on stealth.
Of course, if it is really developed, God knows whether the outside world will celebrate that Shen Hoy successfully captured Chengluoma?
"It's already very good. Take your time and don't be in a hurry. I'll go back and see what your concept map looks like."
Zhou Hai looked at Zuo Xue's somewhat lonely look and comforted him: "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 off than you, your feelings of loss and pessimism will be reduced a lot. After all, isn’t it right to enjoy hardship?
"Strategically, we must despise the enemy. Tactically, we must pay attention to the enemy. Don't underestimate the mind. This is a fourth-generation fighter aircraft designed with the YF-23 aerodynamic shape. Although it has many shortcomings, from the perspective of flight design, the mind is small due to its size. It is reduced and compact, the edges and structure are optimized, and the stealth capability reaches an excellent level. According to my analysis, there are only 10 reflection lobes, second only to the F-22."
When it comes to the country on the other side of the ocean, Zuo Xue has a solemn face, a correct mentality, and no slightest contempt. He points out the advantages and disadvantages one by one from the perspective of an aircraft designer, and comments: "The little devil has the ambition to revitalize the aviation industry. There was hope, but there was a lack of manufacturing experience and technology. After decades of hard work, nothing came of it, and a good aerodynamic layout was lost."
Japan's ATD-X 'Shin' fighter is based on the YF-23 'Black Widow' fighter that was defeated that year, and has extremely excellent aerodynamic design.
At that time, the YF-23 'Black Widow' and the YF-22 'Raptor' competed for the development model of the US military's advanced tactical fighter contract. The reason for their defeat was not that they were lagging behind in technology and performance, but that they were overall superior to the Raptor.
At the beginning of the 21st century, when it was announced that the countries on the other side of the ocean were planning to develop the ATD-X "Psychic" fighter jet, it caused a sensation all over the world and caused unprecedented pressure and shock to various regions in Asia.
In 2000, our own Air Force was still using a large number of second-generation aircraft such as J-6, J-7 and J-8, and imported a small amount of Su-27. The J-10 had not officially entered service. Facing the F- The 15J fleet was already having a hard time, but suddenly something came to their mind, which scared many people and kept them awake all night.
However,
A year has passed,
Ten years have passed,
Twenty years have passed.
The airline crew, who were so frightened at the time, went from having the courage to face it to moving forward bravely, from being frightened to looking confused, with a hint of confusion.
Where's the goods?
Where's the stuff?
Where is your mind?
The rumored overwhelming aircraft fleet has not appeared in the skies of Asia to show off its power. It is still the F-15J and a small number of F-2 fleets that imitate the F-16 'Falcon' that carry the main beam.
The idea based on the 'Black Widow' has been going back and forth to this day, spanning twenty years. Under the slogan of 'experimental machine', the eight-ton empty-weight experimental machine has only made a few first flights.
The experimental machine is not like the experimental machine, and the overall performance of the mass-produced machine is too poor to meet the standards. Coupled with various technical problems and pressure from the United States, everyone was panic-stricken at that time, and was in an embarrassing state of neither getting better nor worse.
After the J-20 was born and the FC-31 gradually matured, the status of self-research and development dropped again. In desperation, the Japanese team had no choice but to purchase F-35 to counter it.
Although I am not feeling well, it is undeniable that the aerodynamic layout meets the stealth standard and is excellent.
We should not only see the shortcomings, but also see the shining points.
As an aircraft designer, when the engine is not powerful, he can only rack his brains, use his imagination and creativity, and design the most suitable aerodynamic layout 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 work she created.
The sky was dark and night was falling. Facing the river wind, they left Wentian Terrace all the way and hailed a taxi. The two of them quickly took the taxi back to the Red Maple Hotel.
She didn't go shopping to buy clothes or shoes, mainly because the red wine was gradually getting stronger. The girl Zuo Xue was still conscious, but her body was a little weak.
It is impossible to go shopping anymore, it is better to 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 hot air, tried to straighten her back, opened the locked luggage backpack, took out a carefully kept picture album, and handed it to Zhou Hai, with a smile on her pretty red face: "There's me in it. I created Z-1 and several other designs that are more sci-fi and avant-garde. I like Z-3 the best. This is a small gift for you, keep it safe."
Other girls give gifts only small items, but this girl is better, just an exquisite concept picture book of fighter planes, all original and carefully crafted.
Zhou Hai nodded, took the album, and turned to the first page. The avant-garde and detailed Z-1 fourth-generation stealth concept drawing came into view.
The concept drawing can barely be regarded as an initial blueprint. It contains three views of the front and upper sides with different directions. Thin blue lines accurately outline the entire fighter aircraft. There are no canards, a central trapezoidal main wing, and the vertical tail is cambered in the upper and lower areas of the fuselage. , with smooth lines and sharp edges, strictly maintaining the design requirements of the stealth theory and minimizing radar scattering.
The wing edge strips are processed to increase the coefficient that is beneficial to interference vortices. DSI air inlets on both sides are designed to further reduce radar scattering. The ailerons and horizontal stabilizers are both trapezoidal surfaces.
