"Okay, then we'll call and meet at a certain time!" Li Yishen nodded. Wu Tong is not a three-year-old child. Even though they are worried about Wu Tong's safety, they cannot follow him too closely, lest the child feel constrained and easily rebel.
The security of the conference venue is guaranteed. Wu Tong is not a willful child. He will not leave the venue and will do what he says, so he is relieved.
"If you encounter any problems, don't get into any fights with anyone. Contact us immediately!" Li Yisheng repeatedly instructed as they signed separately. "Keep our phones turned on."
The venue was politely silent, but that didn't affect their ringtones, which were switched to vibrate, making them easier to feel when held in their hands. Their most important task at this conference was to take good care of Wu Tong.
"No problem!" Wu Tong made an OK gesture and headed towards her first goal, a report on partial differential equations. Partial differential equations are necessary content for studying fluid mechanics.
"The existence and uniqueness of solutions, their extensibility, and their dependence on initial conditions, and further consideration of linear equations..." The lecture on dynamical systems and ordinary calculus equations was given by Professor Fu from China.
Wu Tong arrived quietly, found an inconspicuous corner, listened quietly and attentively, and made some important notes from time to time, or recorded the fragments of insights aroused by the collision of thoughts.
Different fields have different meanings. Her knowledge of mathematics can be said to be top-notch in the country, but when it comes to dynamics or engines, she is a complete newbie.
Most of the information she found online was general and incomplete. After returning from Mount Tai, she found a lot of books and information on this subject from Peking University and international channels.
After careful study, she was able to understand the theoretical knowledge section, but her knowledge and foundation were too shallow. She felt that she was still learning castles in the air and had not officially started.
When Wu Tong saw the title of this group, he became interested and arranged time to come and listen.
"···According to the power··conversion model···"
At the end of the report, Wu Tong nodded slightly, feeling somewhat enlightened! Why did she have to embarrass herself in the dynamics community? Wouldn't it be better to transform it into a mathematical problem and build a mathematical model? Mathematics was her foundation at the moment.
What she wanted to achieve was not to build a new engine from scratch, but to find an optimization direction and angle, and use mathematical models to calculate and deduce better parameters. This was her strong point!
It's really putting the cart before the horse, getting half the result with twice the effort, and being limited by inherent thinking!
However, her research on dynamics was not in vain. Conversion problems also require some basic knowledge. Recently, research on fluid mechanics and dynamics has increased day by day. Her ideas have gradually extended from the engine that she was initially interested in to all the areas within her sight.
Several parameters jumped into her mind, and Wu Tong lowered her head and began to calculate them smoothly on her notebook.
With the central axis as the horizontal, the wind resistance is X, the maximum flight speed is 2.5 Mach, the length is 18.90 meters, the wingspan is 13.56, the height is 5.08 meters, the fuselage area is 78.04, and the empty weight is...
The impact force of the rectangular cross section is..., with a medium sweep angle, it is calculated that the inclination angle of the side of the middle machine is 35 degrees... Synchronous lift-to-drag ratio...
Based on some of the parameters she had seen, Wu Tong began to transform the mathematical problem into a mathematical model, calculating and converting it into ideal data. Because of the sensitive issues involved, Wu Tong directly used metaphors or circled specific symbols for many of the terms, and the entire complex calculation and deduction became a cipher that only Wu Tong could understand.
At the side, there was a Western student who came to study with the teacher. During the test, he accidentally saw a corner of Wu Tong's notes. He was instantly frightened and looked away. He couldn't understand it. Where did this big guy come from? Are all Orientals so good at mathematics?
Any random Oriental student you meet is so impressive! And what about the internationally renowned Wu Tong? It's no secret that this year's rise has been nothing short of overwhelming.
After the report, Wu Tong closed his notebook and followed the crowd out of the venue. He met Li Yishen at the entrance and returned to his hotel room.
It was already the afternoon of the second day after the opening ceremony, and Wu Tong had some thoughts after the last report of the day.
After dinner, I told Teacher Li that she would prepare for the afternoon lecture tomorrow at noon and sort out what she had learned in the past few days. She would not go out at noon tomorrow, so there was no need to wait for her.
After returning to the room, Wu Tong seemed like a child who had discovered a new toy. He continued to calculate with great interest, filling in the gaps in the mathematical model he had initially built in the afternoon.
In the absolute space where she was the only one, Wu Tong did not hide anything any more. As she calculated, she picked up a ruler and tried to draw a picture. The half-blurred shape of the plane gradually took shape under her hands. She marked the calculated data in the appropriate position step by step.
The F-22 Raptor, a highly advanced fighter jet of our time, officially entered combat service in 2007. For countless countries, it was a force to be reckoned with, day and night, for its sudden beyond-visual-range appearance, dimensionality-reduction strike, and commanding air superiority. It was also a force that countless Chinese researchers toiled tirelessly, day and night, to catch up with and surpass.
Wu Tong's impression and data about it came from an inadvertent glance in her future memory. It had been quietly buried in her memory before, but at today's report meeting, she was suddenly touched and inadvertently extended her association, awakening this bit of memory.
Based on what she had recently learned, she began to convert some of the data she had dug out from her memory into a mathematical model from the perspective of fluid mechanics, aerodynamics, etc., and then, with the help of absolute direction and absolute deduction capabilities, she began to reversely restore the appearance data.
Some of the data may not match the original, missing precise data, but this is the optimal data calculated by Wu Tong using a mathematical model based on various perspectives of mechanics and dynamics. If it doesn't match the original data, Wu Tong is confident that her data is the optimal choice. The actual model may not achieve the optimal data because the materials and process conditions are not yet able to meet the optimal data.
She actually didn't realize what she was doing at the moment. The definition she gave herself was just a way for her to do some confirmatory inferences and calculations at the right time.
At one o'clock in the afternoon on August 23, a drawing of a fighter jet with a complete shape was born from Wu Tong's pen.
The ridged forebody, sharp wing strips, fuselage, wings, dual vector nozzles... the fuselage layout diagram appears on the plan view, with detailed data densely marked on it with arrows.
In addition to the general shape of the fighter, Wu Tong further calculated the engine's thrust-to-weight ratio. From a materials science perspective, he analyzed the maximum pressure-bearing capacity, density, and mass of the fuselage materials. Which materials currently offer the closest approximation given a limited weight? With limited data at hand, Wu Tong could only make a vague, rough estimate.
Titanium aluminum alloy?
