Chapter 883 Teacher Yao, come and stay in Darian for 7 or 8 years!
Having figured it out, Lao Wang felt that this matter really couldn't be delayed, so he led Staff Officer Xie slowly into the core area of the confidential workshop.
"Brother... there's something you need to know!"
Before Lao Wang could finish speaking, Jiang Xia shoved an oversized flashlight into his hand.
"Don't talk! Raise your hand!"
Old Wang shrugged at Staff Officer Xie and began to raise the extra-long flashlight, which contained a full eight No. 8 batteries.
At this moment, the debate between Jiang Xia and Professor Zhonghua reached a fever pitch.
Jiang Xia pointed to the tiny holes on the turbine disk that were faintly visible under the strong light, and said excitedly, "Professor Zhonghua, take a closer look! The distribution and orientation of these holes are definitely not defects or looseness in the material itself!"
These are meticulously designed and manufactured cooling film vents! And look at the 'fir tree-shaped' tenon joints at the base of the blades…
As he spoke, Jiang Xia beckoned to Old Wang with his finger, and Old Wang understood and shifted the flashlight in his hand at an angle.
As a result, tiny shadows were indeed cast on the otherwise smooth impeller. These tiny holes were arranged in a highly regular pattern.
After taking the picture, Jiang Xia moved his finger again, and Lao Wang precisely shone the flashlight beam on the mortise and tenon joint.
"Look, isn't this configuration unique? This is how the blades are firmly locked onto the rotor under the enormous centrifugal force of tens of thousands of revolutions per minute!"
Professor Zhonghua frowned and took out the magnifying glass hanging around his neck, wanting to carefully observe the air film cooling holes that Jiang Xia had mentioned.
However, he soon discovered that the old thing that had been with him for most of his life was not capable of doing such delicate work.
It's not clear from this perspective.
Just as Jiang Xia was about to reach into his pocket and take out the high-powered magnifying glass he had gotten from Professor Zu Tong, he saw the old professor make a new move.
Professor Zhonghua gestured to his students to adjust the tungsten iodine lamp that provided backlighting for the optical scale system, and then used a piece of thick cardboard that had been rolled up temporarily to shape and shield the intense light beam, creating a concentrated and bright side light.
He adjusted his posture, half-squatting, and pressed the magnifying glass tightly against the surface of the leaf, with one eye almost touching the lens. With the help of the precisely guided beam of light, he carefully observed the leaf again at an extremely close distance and a very tricky angle.
The strong light swept across the edge of the hole, creating tiny reflections inside. Now, some details that were previously difficult to detect were finally faintly visible.
Wow, you can use this method?
Isn't this just a microscope with a light source?
It's a bit old-fashioned...
But our backbone is truly capable of creating miracles no matter where it is placed!
Jiang Xia sighed and handed over a high-powered magnifying glass.
This magnifying glass has quite a history; it was made from the first batch of optical glass made by Professor Zu Tong. I originally wanted to keep it as a souvenir, but for now, let it play its true role!
Professor Zhonghua took the high-powered magnifying glass and began to observe carefully.
"Xiao Jiang," Professor Zhonghua said without looking up, his voice a little hoarse, but with a hint of caution after making a new discovery.
I admit that the design and machining precision of this fir tree-shaped tenon joint truly exceeded my expectations, demonstrating the other party's remarkable precision casting and CNC machining capabilities.
But you said that the inside of the blades, especially the inside of these seemingly uniform high-temperature alloys, is filled with man-made, honeycomb-shaped tiny cooling channels?
"Hmm..."
Professor Zhonghua straightened up, rubbed his sore eyes, and shook his head again. "It's not that I don't believe your deduction, but it's just too..."
According to current technological logic, if the inside of the blade is processed in that way, its strength will drop sharply, and it will inevitably collapse when rotating at high speed.
He pointed to the area he had just carefully observed with the help of strong side lighting: "I am more inclined to believe that the surface holes you see are traces left on the surface by the inherent dendrite shrinkage cavities or element segregation inside the material during some special directional solidification or single crystal casting process, in order to control the solidification direction or reduce internal stress."
They may objectively guide a very small amount of cooling airflow, playing a role in heat dissipation, but this is by no means the dominant cooling method designed actively.
After Professor Zhonghua finished speaking, he stroked his chin and pondered for a moment: "However, I can't say you're wrong..."
"Hey! My knowledge of materials science is a bit lacking. If Tong Bin were here, that would be great. He has a deep understanding of the microstructure and mechanical properties of materials and would definitely be able to see more of the intricacies."
"Is the person you're talking about surnamed Yao?" Jiang Xia's voice was choked with barely perceptible emotion.
"Yes, he should be working at the Aerospace Materials Institute now. I met him once a few years ago, and every time I tried to contact him after that, he said he was busy..."
"Bang!"...
The little guy's head bumped into the side of the impeller casing, and when he looked up again, his eyes were already red...
Professor Zhonghua, who was nearby, reached out his calloused hand and touched the large bump on the forehead of the idiot.
"You child, you're so big and still so impulsive!"
"Waaah..." Jiang Xia used the pain in her head to make her tears flow even more fiercely. These tears were not only for the pain at this moment, but also for the figure who was silently working hard in the field of materials science.
Do you really think that hairy little guy is so fragile?
He was just using this to express his feelings...
Dear Teacher Yao, whom I've never met, your former residence is the only provincial-level cultural relic protection unit in the Xibei area!
Did you know that the brazing structure you proposed still protects those little guys that were originally green but were painted white and transformed into rockets as they soar into the sky?
"Old Wang! Can you use your connections to get Teacher Yao here for me too?"
"what?"
"Hmph! Professor Zhonghua doesn't believe this passage was designed intentionally! Then I'll ask a professional to provide my argument!"
"Uh, I can give it a try. But I can't guarantee it!" Old Wang felt he couldn't let his brother lose face, so he reluctantly agreed.
"Don't just try, you have to succeed!"
"It's a bit difficult! Professor Zhonghua already mentioned that the others are from the aviation industry..."
"Brother Wang..."
"Stop! I'll take care of it right away! Also, Staff Officer Xie needs to see you. If you combine these two matters, I'll be more confident!"
"Okay!"
The boy answered with great confidence, having surpassed his master's skill in using the tactic of setting up smaller projects within larger ones—a tactic he learned from his teacher.
Whatever it is, I can always find a connection!
Oh ho ho, Teacher Yao, why don't you just settle down in Darian? It's so nice here.
The sandstorms in Beijing are too strong; it's really not suitable for you!
……
After walking a distance with Staff Officer Xie, Staff Officer Xie handed the telegram in his hand to Jiang Xia.
Then Staff Officer Xie began to explain to Jiang Xia, but after only hearing the beginning, the young man exclaimed, "What? We've run into each other! How are the comrades? Are they alright?!"
Hey, this kid's first reaction was exactly the same as Old Wang's.
"He's alright! He's alright!" Staff Officer Xie felt a warmth in his heart and quickly reassured him.
Jiang Xia didn't want to listen to Staff Officer Xie continue; her small frame couldn't handle such dramatic pronouncements. She'd rather read the telegram...
After reading.
Hey! Isn't this a golden opportunity?
No wonder Old Wang said that connecting these two things would make transferring people much easier...
"Is the commander still online?"
"Yes! They've given instructions that you can speak to him anytime!"
"Then what are we waiting for? Let's go!"
At this moment, Jiangxia had every reason to transfer people!
