Scientific research results.
This word is familiar to everyone, and to those involved in the national defense scientific research system and the national scientific research system, it is a word of extraordinary significance that is often spoken all day long.
Compared with national defense researchers who have scientific research achievements and those who have no scientific research achievements, they are completely different things.
The former shows that they are mature and qualified and have officially joined the scientific research team, while the latter shows that they still have shortcomings and are still struggling in the mud.
In other words, if you have a result, it is still an important second-class achievement. To those peers who are still struggling with proposal reports and dissertations, you are the father.
Well, daddy, the kind of person who makes people obey you when you meet him.
There are results. No matter where you are, once you speak, others will listen silently and have the right to speak.
No results, no matter how boastful your experience is, in the eyes of others, you are just a transparent person who can be ignored at any time. If you talk, others will tell you to shut up and stop disturbing you.
Today, Zuo Xue, who is only 20 years old and still studying for a master's degree in aircraft design at the University of Defense Technology, has won the second-class appearance design award of the Army Science and Technology Award with this second-class personal merit and the "Pufferfish" underwater micro-propulsion project. , can be said to have officially joined the ranks of national defense scientific researchers, with a certain identity and status, as well as the right to speak.
Like a young star that has just been condensed and formed in the starry sky, nuclear fusion occurs in the inner core and is officially ignited, releasing light and heat into the surrounding space, announcing its existence.
The light and heat of newborn stars are insignificant and cannot compare with those middle-aged stars that have burned for billions of years, but they belong to stars after all and are by no means small and fragile planets.
With the second prize of the Military Science and Technology Progress Award awarded by the Equipment Development Department of the National Military Commission, Zuo Xue, like a newborn star, announced her existence to the national defense scientific research system. She is no longer the unknown existence she was before.
"Thank you, teacher." After hearing what the teacher Yang Wei said, Zuo Xue knew what it meant. Su Rui's gentle and smiling face appeared in her mind. Her words were full of respect, and she said thank you in a solemn voice.
Thanks to Yang Wei and Su Rui.
The move of his mentor Su Rui to ask his teacher Yang Wei to announce the news is of great significance. It is equivalent to conveying two pieces of information to relevant insiders——
First, Zuo Xue belongs to the Chengdu Flying System and has long been famous.
Second, Zuo Xue is a student of Yang Wei, and there is someone standing behind him.
After completing the thesis defense in two months and officially receiving a master's degree in aircraft design, Zuo Xue should leave the National University of Defense Technology and work at Chengdu Aircraft Manufacturing Company.
"Thank you. It's a small thing. As long as you do a good job in research and give full play to your talents, that's enough. I'm still waiting for you to take over my class."
Yang Wei's voice was gentle, and he didn't care about the false etiquette. Then he remembered something and asked curiously: "By the way, I heard from Lao Su that you are interested in fifth-generation aircraft. How is the situation? Do you have any ideas?"
talent.
In Zuo Xue, Yang Wei saw with his own eyes that he had a top-notch aircraft design talent that was no different from his own, and even slightly exceeded it.
This is a surprising discovery.
Moreover, Zuo Xue was actually from Sichuan Province, which made Yang Wei feel a sense of intimacy.
It is precisely because of this that Yang Wei, who is an academician but has never taught a doctoral student, really became interested in accepting Zuo Xue as a disciple after meeting Zuo Xue in person last time. He immediately accepted Zuo Xue into the Chengfei system, and Train according to the standards of successors.
Take over!
Take over the banner and team that belongs to Chengfei alone, and lead Chengfei to continue moving forward towards glory and glory!
Yang Wei, who became famous after launching the J-20 Veyron project, is now 57 years old, just like an old star who is about to countdown to his death.
In three years, he will be sixty, and he is already old.
But Zuo Xue is different. She is only twenty years old this year and her scientific research path has just begun.
Being young means infinite possibilities.
"Teacher, you are joking. You are Chengfei's pillar. I am still early. I do have some ideas about the fifth-generation aircraft. I just wrote the first draft of the research on the fifth-generation aircraft today." Zuo Xue responded with a smile and sat down again. Next, current information about the fifth-generation aircraft project is given.
On the phone, Yang Wei showed a hint of interest, and his words were full of interest. He wanted to hear the opinions of his apprentice: "Oh? Tell me what you think."
"I use a small aspect ratio aerodynamic layout with no vertical tail and variable forward sweep wing. The specific structure is close coupling canard + side wing + variable forward sweep wing. The maximum forward sweep angle is 40°. The forward sweep angle is retracted and the body changes. It is a wedge-shaped waverider, and the lift coefficient in the subsonic stage is about 3.5."
Zuo Xue glanced at the first draft of the paper on the Z-2 fighter aircraft with the cursor symbol flashing on the computer screen, and told her teacher Yang Wei about the basic parameters and design ideas of the Z-2 fifth-generation aircraft.
The other end of the phone fell into silence. As Zuo Xue gave the basic parameters and information of the Z-2 fifth-generation machine, Yang Wei did not refute, thinking quietly, and conceived in his mind based on a series of information.
silence.
There was a dead silence on the phone.
Zuo Xue held the confidential mobile phone, her breathing was steady, her face was natural, and she waited quietly, even though she knew how shocking and unorthodox her fifth-generation machine design idea was.
Well, yes, shocking and outrageous.
The former is attributed to the basic aerodynamic parameters of the Z-2 fifth-generation fighter. Anyone with a little knowledge of aerodynamics can understand the significance of the wedge-shaped waverider and the lift coefficient of 3.5.
If nothing else, take the two most cutting-edge fourth-generation fighters in the world as examples. The F-22, which is full of brilliance and is known as the best in the world, has a lift coefficient of about 1.6. The J-20' has been controversial and criticized. Dragon', lift coefficient 2.1.
The lift coefficient difference between the two is exactly 0.5, which is almost the same level.
The small aspect ratio fighter has a lift coefficient of 3.5, which is an extremely exaggerated and terrifying aerodynamic performance parameter.
The latter is rooted in the idea of variable forward-swept wings. The aerodynamic design performance of forward-swept wings is extremely excellent, much higher than that of swept wings and delta wings, but there is an unavoidable fatal problem - aeroelastic divergence.
"Your idea is very bold, and I am very satisfied with this. Variable forward-swept wings without vertical tails are generally feasible and meet the high maneuverability and high stealth requirements of fifth-generation aircraft."
At this time, Yang Wei's gentle and natural voice came from the other end of the phone, and said seriously: "The forward sweep angle of the wing is 40°, which meets the performance of subsonic high maneuverability and supersonic speed. The forward sweep angle of the wing is reduced and then transformed into a wedge shape. The waverider can achieve the aerodynamic requirements for hypersonic flight above Mach 5, but how to solve the aeroelastic divergence problem of forward-swept wing design?"
Aeroelastic divergence.
How to solve this problem that can never be avoided in the field of forward swept wings?
PS: I wrote it wrong before, it’s not mid-range, it’s close-coupled canard.
